text: Recent advances in synthetic posttranslational protein circuits are substantially
impacting the landscape of cellular engineering and offer several advantages compared
to traditional gene circuits. However, engineering dynamic phenomena such as oscillations
in protein-level circuits remains an outstanding challenge. Few examples of biological
posttranslational oscillators are known, necessitating theoretical progress to
determine realizable oscillators. We construct mathematical models for two posttranslational
oscillators, using few components that interact only through reversible binding
and phosphorylation/dephosphorylation reactions. Our designed oscillators rely
on the self-assembly of two protein species into multimeric functional enzymes
that respectively inhibit and enhance this self-assembly. We limit our analysis
to within experimental constraints, finding (i) significant portions of the restricted
parameter space yielding oscillations and (ii) that oscillation periods can be
tuned by several orders of magnitude using recent advances in computational protein
design. Our work paves the way for the rational design and realization of protein-based
dynamic systems.

text: "We settle the complexity of the (Δ+1)-coloring and (Δ+1)-list coloring problems
in the CONGESTED CLIQUE model by presenting a simple deterministic algorithm for
both problems running in a constant number of rounds. This matches the complexity
of the recent breakthrough randomized constant-round (Δ+1)-list coloring algorithm
due to Chang et al. (PODC'19), and significantly improves upon the state-of-the-art
O(logΔ)-round deterministic (Δ+1)-coloring bound of Parter (ICALP'18).\r\nA remarkable
property of our algorithm is its simplicity. Whereas the state-of-the-art randomized
algorithms for this problem are based on the quite involved local coloring algorithm
of Chang et al. (STOC'18), our algorithm can be described in just a few lines.
At a high level, it applies a careful derandomization of a recursive procedure
which partitions the nodes and their respective palettes into separate bins. We
show that after O(1) recursion steps, the remaining uncolored subgraph within
each bin has linear size, and thus can be solved locally by collecting it to a
single node. This algorithm can also be implemented in the Massively Parallel
Computation (MPC) model provided that each machine has linear (in n, the number
of nodes in the input graph) space.\r\nWe also show an extension of our algorithm
to the MPC regime in which machines have sublinear space: we present the first
deterministic (Δ+1)-list coloring algorithm designed for sublinear-space MPC,
which runs in O(logΔ+loglogn) rounds."

text: "We consider the following decision problem EMBEDk→d in computational topology
(where k ≤ d are fixed positive integers): Given a finite simplicial complex K
of dimension k, does there exist a (piecewise-linear) embedding of K into ℝd?\r\nThe
special case EMBED1→2 is graph planarity, which is decidable in linear time, as
shown by Hopcroft and Tarjan. In higher dimensions, EMBED2→3 and EMBED3→3 are
known to be decidable (as well as NP-hard), and recent results of Čadek et al.
in computational homotopy theory, in combination with the classical Haefliger–Weber
theorem in geometric topology, imply that EMBEDk→d can be solved in polynomial
time for any fixed pair (k, d) of dimensions in the so-called metastable range
.\r\nHere, by contrast, we prove that EMBEDk→d is algorithmically undecidable
for almost all pairs of dimensions outside the metastable range, namely for .
This almost completely resolves the decidability vs. undecidability of EMBEDk→d
in higher dimensions and establishes a sharp dichotomy between polynomial-time
solvability and undecidability.\r\nOur result complements (and in a wide range
of dimensions strengthens) earlier results of Matoušek, Tancer, and the second
author, who showed that EMBEDk→d is undecidable for 4 ≤ k ϵ {d – 1, d}, and NP-hard
for all remaining pairs (k, d) outside the metastable range and satisfying d ≥
4."

text: 'Scientific research is to date largely restricted to wealthy laboratories
in developed nations due to the necessity of complex and expensive equipment.
This inequality limits the capacity of science to be used as a diplomatic channel.
Maker movements use open-source technologies including additive manufacturing
(3D printing) and laser cutting, together with low-cost computers for developing
novel products. This movement is setting the groundwork for a revolution, allowing
scientific equipment to be sourced at a fraction of the cost and has the potential
to increase the availability of equipment for scientists around the world. Science
education is increasingly recognized as another channel for science diplomacy.
In this perspective, we introduce the idea that the Maker movement and open-source
technologies have the potential to revolutionize science, technology, engineering
and mathematics (STEM) education worldwide. We present an open-source STEM didactic
tool called SCOPES (Sparking Curiosity through Open-source Platforms in Education
and Science). SCOPES is self-contained, independent of local resources, and cost-effective.
SCOPES can be adapted to communicate complex subjects from genetics to neurobiology,
perform real-world biological experiments and explore digitized scientific samples.
We envision such platforms will enhance science diplomacy by providing a means
for scientists to share their findings with classrooms and for educators to incorporate
didactic concepts into STEM lessons. By providing students the opportunity to
design, perform, and share scientific experiments, students also experience firsthand
the benefits of a multinational scientific community. We provide instructions
on how to build and use SCOPES on our webpage: http://scopeseducation.org.'

text: In this paper, we establish convergence to equilibrium for a drift–diffusion–recombination
system modelling the charge transport within certain semiconductor devices. More
precisely, we consider a two-level system for electrons and holes which is augmented
by an intermediate energy level for electrons in so-called trapped states. The
recombination dynamics use the mass action principle by taking into account this
additional trap level. The main part of the paper is concerned with the derivation
of an entropy–entropy production inequality, which entails exponential convergence
to the equilibrium via the so-called entropy method. The novelty of our approach
lies in the fact that the entropy method is applied uniformly in a fast-reaction
parameter which governs the lifetime of electrons on the trap level. Thus, the
resulting decay estimate for the densities of electrons and holes extends to the
corresponding quasi-steady-state approximation.

text: We explore the time evolution of two impurities in a trapped one-dimensional
Bose gas that follows a change of the boson-impurity interaction. We study the
induced impurity-impurity interactions and their effect on the quench dynamics.
In particular, we report on the size of the impurity cloud, the impurity-impurity
entanglement, and the impurity-impurity correlation function. The presented numerical
simulations are based upon the variational multilayer multiconfiguration time-dependent
Hartree method for bosons. To analyze and quantify induced impurity-impurity correlations,
we employ an effective two-body Hamiltonian with a contact interaction. We show
that the effective model consistent with the mean-field attraction of two heavy
impurities explains qualitatively our results for weak interactions. Our findings
suggest that the quench dynamics in cold-atom systems can be a tool for studying
impurity-impurity correlations.

text: 'We define and study a discrete process that generalizes the convex-layer
decomposition of a planar point set. Our process, which we call homotopic curve
shortening (HCS), starts with a closed curve (which might self-intersect) in the
presence of a set P⊂ ℝ² of point obstacles, and evolves in discrete steps, where
each step consists of (1) taking shortcuts around the obstacles, and (2) reducing
the curve to its shortest homotopic equivalent. We find experimentally that, if
the initial curve is held fixed and P is chosen to be either a very fine regular
grid or a uniformly random point set, then HCS behaves at the limit like the affine
curve-shortening flow (ACSF). This connection between HCS and ACSF generalizes
the link between "grid peeling" and the ACSF observed by Eppstein et al. (2017),
which applied only to convex curves, and which was studied only for regular grids.
We prove that HCS satisfies some properties analogous to those of ACSF: HCS is
invariant under affine transformations, preserves convexity, and does not increase
the total absolute curvature. Furthermore, the number of self-intersections of
a curve, or intersections between two curves (appropriately defined), does not
increase. Finally, if the initial curve is simple, then the number of inflection
points (appropriately defined) does not increase.'

text: 'We prove general topological Radon-type theorems for sets in ℝ^d, smooth
real manifolds or finite dimensional simplicial complexes. Combined with a recent
result of Holmsen and Lee, it gives fractional Helly theorem, and consequently
the existence of weak ε-nets as well as a (p,q)-theorem. More precisely: Let X
be either ℝ^d, smooth real d-manifold, or a finite d-dimensional simplicial complex.
Then if F is a finite, intersection-closed family of sets in X such that the ith
reduced Betti number (with ℤ₂ coefficients) of any set in F is at most b for every
non-negative integer i less or equal to k, then the Radon number of F is bounded
in terms of b and X. Here k is the smallest integer larger or equal to d/2 - 1
if X = ℝ^d; k=d-1 if X is a smooth real d-manifold and not a surface, k=0 if X
is a surface and k=d if X is a d-dimensional simplicial complex. Using the recent
result of the author and Kalai, we manage to prove the following optimal bound
on fractional Helly number for families of open sets in a surface: Let F be a
finite family of open sets in a surface S such that the intersection of any subfamily
of F is either empty, or path-connected. Then the fractional Helly number of F
is at most three. This also settles a conjecture of Holmsen, Kim, and Lee about
an existence of a (p,q)-theorem for open subsets of a surface.'

text: 'Let K be a convex body in ℝⁿ (i.e., a compact convex set with nonempty interior).
Given a point p in the interior of K, a hyperplane h passing through p is called
barycentric if p is the barycenter of K ∩ h. In 1961, Grünbaum raised the question
whether, for every K, there exists an interior point p through which there are
at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly
resolved affirmatively by showing that this is the case if p=p₀ is the point of
maximal depth in K. However, while working on a related question, we noticed that
one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample;
this re-opens Grünbaum’s question. It follows from known results that for n ≥
2, there are always at least three distinct barycentric cuts through the point
p₀ ∈ K of maximal depth. Using tools related to Morse theory we are able to improve
this bound: four distinct barycentric cuts through p₀ are guaranteed if n ≥ 3.'

text: In the recent study of crossing numbers, drawings of graphs that can be extended
to an arrangement of pseudolines (pseudolinear drawings) have played an important
role as they are a natural combinatorial extension of rectilinear (or straight-line)
drawings. A characterization of the pseudolinear drawings of K_n was found recently.
We extend this characterization to all graphs, by describing the set of minimal
forbidden subdrawings for pseudolinear drawings. Our characterization also leads
to a polynomial-time algorithm to recognize pseudolinear drawings and construct
the pseudolines when it is possible.

text: 'Relaxation to a thermal state is the inevitable fate of nonequilibrium interacting
quantum systems without special conservation laws. While thermalization in one-dimensional
systems can often be suppressed by integrability mechanisms, in two spatial dimensions
thermalization is expected to be far more effective due to the increased phase
space. In this work we propose a general framework for escaping or delaying the
emergence of the thermal state in two-dimensional arrays of Rydberg atoms via
the mechanism of quantum scars, i.e., initial states that fail to thermalize.
The suppression of thermalization is achieved in two complementary ways: by adding
local perturbations or by adjusting the driving Rabi frequency according to the
local connectivity of the lattice. We demonstrate that these mechanisms allow
us to realize robust quantum scars in various two-dimensional lattices, including
decorated lattices with nonconstant connectivity. In particular, we show that
a small decrease of the Rabi frequency at the corners of the lattice is crucial
for mitigating the strong boundary effects in two-dimensional systems. Our results
identify synchronization as an important tool for future experiments on two-dimensional
quantum scars.'

text: "We present a generative model of images that explicitly reasons over the
set\r\nof objects they show. Our model learns a structured latent representation
that\r\nseparates objects from each other and from the background; unlike prior
works,\r\nit explicitly represents the 2D position and depth of each object, as
well as\r\nan embedding of its segmentation mask and appearance. The model can
be trained\r\nfrom images alone in a purely unsupervised fashion without the need
for object\r\nmasks or depth information. Moreover, it always generates complete
objects,\r\neven though a significant fraction of training images contain occlusions.\r\nFinally,
we show that our model can infer decompositions of novel images into\r\ntheir
constituent objects, including accurate prediction of depth ordering and\r\nsegmentation
of occluded parts."

text: "Here, we employ micro- and nanosized cellulose particles, namely paper fines
and cellulose\r\nnanocrystals, to induce hierarchical organization over a wide
length scale. After processing\r\nthem into carbonaceous materials, we demonstrate
that these hierarchically organized materials\r\noutperform the best materials
for supercapacitors operating with organic electrolytes reported\r\nin literature
in terms of specific energy/power (Ragone plot) while showing hardly any capacity\r\nfade
over 4,000 cycles. The highly porous materials feature a specific surface area
as high as\r\n2500 m2ˑg-1 and exhibit pore sizes in the range of 0.5 to 200 nm
as proven by scanning electron\r\nmicroscopy and N2 physisorption. The carbonaceous
materials have been further investigated\r\nby X-ray photoelectron spectroscopy
and RAMAN spectroscopy. Since paper fines are an\r\nunderutilized side stream

to prepare carbonaceous materials with outstanding performance in electrochemical\r\napplications. "

text: Physical and biological systems often exhibit intermittent dynamics with bursts
or avalanches (active states) characterized by power-law size and duration distributions.
These emergent features are typical of systems at the critical point of continuous
phase transitions, and have led to the hypothesis that such systems may self-organize
at criticality, i.e. without any fine tuning of parameters. Since the introduction
of the Bak-Tang-Wiesenfeld (BTW) model, the paradigm of self-organized criticality
(SOC) has been very fruitful for the analysis of emergent collective behaviors
in a number of systems, including the brain. Although considerable effort has
been devoted in identifying and modeling scaling features of burst and avalanche
statistics, dynamical aspects related to the temporal organization of bursts remain
often poorly understood or controversial. Of crucial importance to understand
the mechanisms responsible for emergent behaviors is the relationship between
active and quiet periods, and the nature of the correlations. Here we investigate
the dynamics of active (θ-bursts) and quiet states (δ-bursts) in brain activity
during the sleep-wake cycle. We show the duality of power-law (θ, active phase)
and exponential-like (δ, quiescent phase) duration distributions, typical of SOC,
jointly emerge with power-law temporal correlations and anti-correlated coupling
between active and quiet states. Importantly, we demonstrate that such temporal
organization shares important similarities with earthquake dynamics, and propose
that specific power-law correlations and coupling between active and quiet states
are distinctive characteristics of a class of systems with self-organization at
criticality.

text: Discrete Morse theory has recently lead to new developments in the theory
of random geometric complexes. This article surveys the methods and results obtained
with this new approach, and discusses some of its shortcomings. It uses simulations
to illustrate the results and to form conjectures, getting numerical estimates
for combinatorial, topological, and geometric properties of weighted and unweighted
Delaunay mosaics, their dual Voronoi tessellations, and the Alpha and Wrap complexes
contained in the mosaics.

text: The main idea behind the Core Project is to teach first year students at IST
scientific communication skills and let them practice by presenting their research
within an interdisciplinary environment. Over the course of the first semester,
students participated in seminars, where they shared their results with the colleagues
from other fields and took part in discussions on relevant subjects. The main
focus during this sessions was on delivering the information in a simplified and
comprehensible way, going into the very basics of a subject if necessary. At the
end, the students were asked to present their research in the written form to
exercise their writing skills. The reports were gathered in this document. All
of them were reviewed by the teaching assistants and write-ups illustrating unique
stylistic features and, in general, an outstanding level of writing skills, were
honorably mentioned in the section "Selected Reports".

text: Understanding how the activity of membrane receptors and cellular signaling
pathways shapes cell behavior is of fundamental interest in basic and applied
research. Reengineering receptors to react to light instead of their cognate ligands
allows for generating defined signaling inputs with high spatial and temporal
precision and facilitates the dissection of complex signaling networks. Here,
we describe fundamental considerations in the design of light-regulated receptor
tyrosine kinases (Opto-RTKs) and appropriate control experiments. We also introduce
methods for transient receptor expression in HEK293 cells, quantitative assessment
of signaling activity in reporter gene assays, semiquantitative assessment of
(in)activation time courses through Western blot (WB) analysis, and easy to implement
light stimulation hardware.

text: Birch pollen allergy is among the most prevalent pollen allergies in Northern
and Central Europe. This IgE-mediated disease can be treated with allergen immunotherapy
(AIT), which typically gives rise to IgG antibodies inducing tolerance. Although
the main mechanisms of allergen immunotherapy (AIT) are known, questions regarding
possible Fc-mediated effects of IgG antibodies remain unanswered. This can mainly
be attributed to the unavailability of appropriate tools, i.e., well-characterised
recombinant antibodies (rAbs). We hereby aimed at providing human rAbs of several
classes for mechanistic studies and as possible candidates for passive immunotherapy.
We engineered IgE, IgG1, and IgG4 sharing the same variable region against the
major birch pollen allergen Bet v 1 using Polymerase Incomplete Primer Extension
(PIPE) cloning. We tested IgE functionality and IgG blocking capabilities using
appropriate model cell lines. In vitro studies showed IgE engagement with FcεRI
and CD23 and Bet v 1-dependent degranulation. Overall, we hereby present fully
functional, human IgE, IgG1, and IgG4 sharing the same variable region against
Bet v 1 and showcase possible applications in first mechanistic studies. Furthermore,
our IgG antibodies might be useful candidates for passive immunotherapy of birch
pollen allergy.

text: "Classic Byzantine fault-tolerant consensus protocols forfeit liveness in
the face of asynchrony in order to preserve safety, whereas most deployed blockchain
protocols forfeit safety in order to remain live. In this work, we achieve the
best of both worlds by proposing a novel abstractions called the finality gadget.
A finality gadget allows for transactions to always optimistically commit but
informs the clients that these transactions might be unsafe. As a result, a blockchain
can execute transactions optimistically and only commit them after they have been
sufficiently and provably audited. In\r\nthis work, we formally model the finality
gadget abstraction, prove that it is impossible to solve it deterministically
in full asynchrony (even though it is stronger than consensus) and provide a partially
synchronous protocol which is currently securing a major blockchain. This way
we show that the protocol designer can decouple safety and liveness in order to
speed up recovery from failures. We believe that there can be other types of finality
gadgets that provide weaker safety (e.g., probabilistic) in order to gain more
efficiency and this can depend on the probability that the network is not in synchrony."

text: "Reverse firewalls were introduced at Eurocrypt 2015 by Miro-nov and Stephens-Davidowitz,
as a method for protecting cryptographic protocols against attacks on the devices
of the honest parties. In a nutshell: a reverse firewall is placed outside of
a device and its goal is to “sanitize” the messages sent by it, in such a way
that a malicious device cannot leak its secrets to the outside world. It is typically
assumed that the cryptographic devices are attacked in a “functionality-preserving
way” (i.e. informally speaking, the functionality of the protocol remains unchanged
under this attacks). In their paper, Mironov and Stephens-Davidowitz construct
a protocol for passively-secure two-party computations with firewalls, leaving
extension of this result to stronger models as an open question.\r\nIn this paper,
we address this problem by constructing a protocol for secure computation with
firewalls that has two main advantages over the original protocol from Eurocrypt
2015. Firstly, it is a multiparty computation protocol (i.e. it works for an arbitrary
number n of the parties, and not just for 2). Secondly, it is secure in much stronger
corruption settings, namely in the active corruption model. More precisely: we
consider an adversary that can fully corrupt up to \U0001D45B−1 parties, while
the remaining parties are corrupt in a functionality-preserving way.\r\nOur core
techniques are: malleable commitments and malleable non-interactive zero-knowledge,
which in particular allow us to create a novel protocol for multiparty augmented
coin-tossing into the well with reverse firewalls (that is based on a protocol
of Lindell from Crypto 2001)."

text: "Discrete Gaussian distributions over lattices are central to lattice-based
cryptography, and to the computational and mathematical aspects of lattices more
broadly. The literature contains a wealth of useful theorems about the behavior
of discrete Gaussians under convolutions and related operations. Yet despite their
structural similarities, most of these theorems are formally incomparable, and
their proofs tend to be monolithic and written nearly “from scratch,” making them
unnecessarily hard to verify, understand, and extend.\r\nIn this work we present
a modular framework for analyzing linear operations on discrete Gaussian distributions.
The framework abstracts away the particulars of Gaussians, and usually reduces
proofs to the choice of appropriate linear transformations and elementary linear
algebra. To showcase the approach, we establish several general properties of
discrete Gaussians, and show how to obtain all prior convolution theorems (along
with some new ones) as straightforward corollaries. As another application, we
describe a self-reduction for Learning With Errors (LWE) that uses a fixed number
of samples to generate an unlimited number of additional ones (having somewhat
larger error). The distinguishing features of our reduction are its simple analysis
in our framework, and its exclusive use of discrete Gaussians without any loss
in parameters relative to a prior mixed discrete-and-continuous approach.\r\nAs
a contribution of independent interest, for subgaussian random matrices we prove
a singular value concentration bound with explicitly stated constants, and we
give tighter heuristics for specific distributions that are commonly used for
generating lattice trapdoors. These bounds yield improvements in the concrete
bit-security estimates for trapdoor lattice cryptosystems."

text: "Background: The mitochondrial pyruvate carrier (MPC) plays a central role
in energy metabolism by transporting pyruvate across the inner mitochondrial membrane.
Its heterodimeric composition and homology to SWEET and semiSWEET transporters
set the MPC apart from the canonical mitochondrial carrier family (named MCF or
SLC25). The import of the canonical carriers is mediated by the carrier translocase
of the inner membrane (TIM22) pathway and is dependent on their structure, which
features an even number of transmembrane segments and both termini in the intermembrane
space. The import pathway of MPC proteins has not been elucidated. The odd number
of transmembrane segments and positioning of the N-terminus in the matrix argues
against an import via the TIM22 carrier pathway but favors an import via the flexible
presequence pathway.\r\nResults: Here, we systematically analyzed the import pathways
of Mpc2 and Mpc3 and report that, contrary to an expected import via the flexible
presequence pathway, yeast MPC proteins with an odd number of transmembrane segments
and matrix-exposed N-terminus are imported by the carrier pathway, using the receptor
Tom70, small TIM chaperones, and the TIM22 complex. The TIM9·10 complex chaperones
MPC proteins through the mitochondrial intermembrane space using conserved hydrophobic
motifs that are also required for the interaction with canonical carrier proteins.\r\nConclusions:
The carrier pathway can import paired and non-paired transmembrane helices and
translocate N-termini to either side of the mitochondrial inner membrane, revealing
an unexpected versatility of the mitochondrial import pathway for non-cleavable
inner membrane proteins."

text: The mitochondrial Tim chaperones are responsible for the transport
of membrane proteins across the inter-membrane space to the inner and outer mitochondrial
membranes. TIM9·10, a hexameric 70 kDa protein complex formed by 3 copies of Tim9
and Tim10, guides its clients across the aqueous compartment. The TIM9·10·12 complex
is the anchor point at the inner-membrane insertase complex TIM22. The mechanism
of client transport by TIM9·10 has been resolved recently, but the structure and
subunit composition of the TIM9·10·12 complex remains largely unresolved. Furthermore,
the assembly process of the hexameric TIM chaperones from its subunits remained
elusive. We investigate the structural and dynamical properties of the Tim subunits,
and show that they are highly dynamic. In their non-assembled form, the subunits
behave as intrinsically disordered proteins; when the conserved cysteines of the
CX3C-Xn-CX3C
motifs are formed, short marginally stable α-helices
are formed, which are only fully stabilized upon hexamer formation to the mature
chaperone. Subunits are in equilibrium between their hexamer-embedded and a free
form, with exchange kinetics on a minutes time scale. Joint NMR, small-angle X-ray
scattering and MD simulation data allow us to derive a structural model of the
TIM9·10·12 assembly, which has a 2:3:1 stoichiometry (Tim9:Tim10:Tim12) with a
conserved hydrophobic client-binding groove and flexible N- and C-terminal tentacles.

text: "Arnold diffusion, which concerns the appearance of chaos in classical mechanics,
is one of the most important problems in the fields of dynamical systems and mathematical
physics. Since it was discovered by Vladimir Arnold in 1963, it has attracted
the efforts of some of the most prominent researchers in mathematics. The question
is whether a typical perturbation of a particular system will result in chaotic
or unstable dynamical phenomena. In this groundbreaking book, Vadim Kaloshin and
Ke Zhang provide the first complete proof of Arnold diffusion, demonstrating that
that there is topological instability for typical perturbations of five-dimensional
integrable systems (two and a half degrees of freedom).\r\nThis proof realizes
a plan John Mather announced in 2003 but was unable to complete before his death.
Kaloshin and Zhang follow Mather’s strategy but emphasize a more Hamiltonian approach,
tying together normal forms theory, hyperbolic theory, Mather theory, and weak
KAM theory. Offering a complete, clean, and modern explanation of the steps involved
in the proof, and a clear account of background material, this book is designed
to be accessible to students as well as researchers. The result is a critical
contribution to mathematical physics and dynamical systems, especially Hamiltonian
systems."

text: Chaperones are essential for assisting protein folding, and for transferring
poorly soluble proteins to their functional locations within cells. Hydrophobic
interactions drive promiscuous chaperone–client binding, but our understanding
of how additional interactions enable client specificity is sparse. Here we decipher
what determines binding of two chaperones (TIM8·13, TIM9·10) to different integral
membrane proteins, the all-transmembrane mitochondrial carrier Ggc1, and Tim23
which has an additional disordered hydrophilic domain. Combining NMR, SAXS and
molecular dynamics simulations, we determine the structures of Tim23/TIM8·13 and
Tim23/TIM9·10 complexes. TIM8·13 uses transient salt bridges to interact with
the hydrophilic part of its client, but its interactions to the transmembrane
part are weaker than in TIM9·10. Consequently, TIM9·10 outcompetes TIM8·13 in
binding hydrophobic clients, while TIM8·13 is tuned to few clients with both hydrophilic
and hydrophobic parts. Our study exemplifies how chaperones fine-tune the balance
of promiscuity vs. specificity.

text: We present the results of a friendly competition for formal verification of
continuous and hybrid systems with nonlinear continuous dynamics. The friendly
competition took place as part of the workshop Applied Verification for Continuous
and Hybrid Systems (ARCH) in 2020. This year, 6 tools Ariadne, CORA, DynIbex,
Flow*, Isabelle/HOL, and JuliaReach (in alphabetic order) participated. These
tools are applied to solve reachability analysis problems on six benchmark problems,
two of them featuring hybrid dynamics. We do not rank the tools based on the results,
but show the current status and discover the potential advantages of different
tools.

text: 'A vector addition system with states (VASS) consists of a finite set of states
and counters. A transition changes the current state to the next state, and every
counter is either incremented, or decremented, or left unchanged. A state and
value for each counter is a configuration; and a computation is an infinite sequence
of configurations with transitions between successive configurations. A probabilistic
VASS consists of a VASS along with a probability distribution over the transitions
for each state. Qualitative properties such as state and configuration reachability
have been widely studied for VASS. In this work we consider multi-dimensional
long-run average objectives for VASS and probabilistic VASS. For a counter, the
cost of a configuration is the value of the counter; and the long-run average
value of a computation for the counter is the long-run average of the costs of
the configurations in the computation. The multi-dimensional long-run average
problem given a VASS and a threshold value for each counter, asks whether there
is a computation such that for each counter the long-run average value for the
counter does not exceed the respective threshold. For probabilistic VASS, instead
of the existence of a computation, we consider whether the expected long-run average
value for each counter does not exceed the respective threshold. Our main results
are as follows: we show that the multi-dimensional long-run average problem (a)
is NP-complete for integer-valued VASS; (b) is undecidable for natural-valued
VASS (i.e., nonnegative counters); and (c) can be solved in polynomial time for
probabilistic integer-valued VASS, and probabilistic natural-valued VASS when
all computations are non-terminating.'

text: A graph game is a two-player zero-sum game in which the players move a token
throughout a graph to produce an infinite path, which determines the winner or
payoff of the game. In bidding games, both players have budgets, and in each turn,
we hold an "auction" (bidding) to determine which player moves the token. In this
survey, we consider several bidding mechanisms and study their effect on the properties
of the game. Specifically, bidding games, and in particular bidding games of infinite
duration, have an intriguing equivalence with random-turn games in which in each
turn, the player who moves is chosen randomly. We show how minor changes in the
bidding mechanism lead to unexpected differences in the equivalence with random-turn
games.

text: "The design and implementation of efficient concurrent data structures have\r\nseen
significant attention. However, most of this work has focused on\r\nconcurrent
data structures providing good \\emph{worst-case} guarantees. In real\r\nworkloads,
objects are often accessed at different rates, since access\r\ndistributions may
be non-uniform. Efficient distribution-adaptive data\r\nstructures are known in
the sequential case, e.g. the splay-trees; however,\r\nthey often are hard to
translate efficiently in the concurrent case.\r\n In this paper, we investigate
distribution-adaptive concurrent data\r\nstructures and propose a new design called
the splay-list. At a high level, the\r\nsplay-list is similar to a standard skip-list,
with the key distinction that\r\nthe height of each element adapts dynamically
to its access rate: popular\r\nelements ``move up,'' whereas rarely-accessed elements
decrease in height. We\r\nshow that the splay-list provides order-optimal amortized
complexity bounds for\r\na subset of operations while being amenable to efficient
concurrent\r\nimplementation. Experimental results show that the splay-list can
leverage\r\ndistribution-adaptivity to improve on the performance of classic concurrent\r\ndesigns,
and can outperform the only previously-known distribution-adaptive\r\ndesign in
certain settings."

text: Several realistic spin-orbital models for transition metal oxides go beyond
the classical expectations and could be understood only by employing the quantum
entanglement. Experiments on these materials confirm that spin-orbital entanglement
has measurable consequences. Here, we capture the essential features of spin-orbital
entanglement in complex quantum matter utilizing 1D spin-orbital model which accommodates
SU(2)⊗SU(2) symmetric Kugel-Khomskii superexchange as well as the Ising on-site
spin-orbit coupling. Building on the results obtained for full and effective models
in the regime of strong spin-orbit coupling, we address the question whether the
entanglement found on superexchange bonds always increases when the Ising spin-orbit
coupling is added. We show that (i) quantum entanglement is amplified by strong
spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states
are possible. We complete the latter case by analyzing how the entanglement existing
for intermediate values of spin-orbit coupling can disappear for higher values
of this coupling.

text: Machine learning and formal methods have complimentary benefits and drawbacks.
In this work, we address the controller-design problem with a combination of techniques
from both fields. The use of black-box neural networks in deep reinforcement learning
(deep RL) poses a challenge for such a combination. Instead of reasoning formally
about the output of deep RL, which we call the wizard, we extract from it a decision-tree
based model, which we refer to as the magic book. Using the extracted model as
an intermediary, we are able to handle problems that are infeasible for either
deep RL or formal methods by themselves. First, we suggest, for the first time,
a synthesis procedure that is based on a magic book. We synthesize a stand-alone
correct-by-design controller that enjoys the favorable performance of RL. Second,
we incorporate a magic book in a bounded model checking (BMC) procedure. BMC allows
us to find numerous traces of the plant under the control of the wizard, which
a user can use to increase the trustworthiness of the wizard and direct further
training.

text: 'From rock salt to nanoparticle superlattices, complex structure can emerge
from simple building blocks that attract each other through Coulombic forces1-4.
On the micrometre scale, however, colloids in water defy the intuitively simple
idea of forming crystals from oppositely charged partners, instead forming non-equilibrium
structures such as clusters and gels5-7. Although various systems have been engineered
to grow binary crystals8-11, native surface charge in aqueous conditions has not
been used to assemble crystalline materials. Here we form ionic colloidal crystals
in water through an approach that we refer to as polymer-attenuated Coulombic
self-assembly. The key to crystallization is the use of a neutral polymer to keep
particles separated by well defined distances, allowing us to tune the attractive
overlap of electrical double layers, directing particles to disperse, crystallize
or become permanently fixed on demand. The nucleation and growth of macroscopic
single crystals is demonstrated by using the Debye screening length to fine-tune
assembly. Using a variety of colloidal particles and commercial polymers, ionic
colloidal crystals isostructural to caesium chloride, sodium chloride, aluminium
diboride and K4C60 are selected according to particle size ratios. Once fixed
by simply diluting out solution salts, crystals are pulled out of the water for
further manipulation, demonstrating an accurate translation from solution-phase
assembly to dried solid structures. In contrast to other assembly approaches,
in which particles must be carefully engineered to encode binding information12-18,
polymer-attenuated Coulombic self-assembly enables conventional colloids to be
used as model colloidal ions, primed for crystallization. '

text: The goal of this study is to understand the mechanisms controlling the isotopic
composition of the water vapor near the surface of tropical oceans, at the scale
of about a hundred kilometers and a month. In the tropics, it has long been observed
that the isotopic compositions of rain and vapor near the surface are more depleted
when the precipitation rate is high. This is called the “amount effect.” Previous
studies, based on observations or models with parameterized convection, have highlighted
the roles of deep convective and mesoscale downdrafts and rain evaporation. But
the relative importance of these processes has never been quantified. We hypothesize
that it can be quantified using an analytical model constrained by large‐eddy
simulations. Results from large‐eddy simulations confirm that the classical amount
effect can be simulated only if precipitation rate changes result from changes
in the large‐scale circulation. We find that the main process depleting the water
vapor compared to the equilibrium with the ocean is the fact that updrafts stem
from areas where the water vapor is more enriched. The main process responsible
for the amount effect is the fact that when the large‐scale ascent increases,
isotopic vertical gradients are steeper, so that updrafts and downdrafts deplete
the subcloud layer more efficiently.

text: Nearly all regions in the world are projected to become dryer in a warming
climate. Here, we investigate the Mediterranean region, often referred to as a
climate change “hot spot”. From regional climate simulations, it is shown that
although enhanced warming and drying over land is projected, the spatial pattern
displays high variability. Indeed, drying is largely caused by enhanced warming
over land. However, in Northern Europe, soil moisture alleviates warming induced
drying by up to 50% due to humidity uptake from land. In already arid regions,
the Mediterranean Sea is generally the only humidity source, and drying is only
due to land warming. However, over Sahara and the Iberian Peninsula, enhanced
warming over land is insufficient to explain the extreme drying. These regions
are also isolated from humidity advection by heat lows, which are cyclonic circulation
anomalies associated with surface heating over land. The cyclonic circulation
scales with the temperature gradient between land and ocean which increases with
climate change, reinforcing the cyclonic circulation over Sahara and the Iberian
Peninsula, both diverting the zonal advection of humidity to the south of the
Iberian Peninsula. The dynamics are therefore key in the warming and drying of
the Mediterranean region, with extreme aridification over the Sahara and Iberian
Peninsula. In these regions, the risk for human health due to the thermal load
which accounts for air temperature and humidity is therefore projected to increase
significantly with climate change at a level of extreme danger.

text: This paper reviews recent important advances in our understanding of the response
of precipitation extremes to warming from theory and from idealized cloud-resolving
simulations. A theoretical scaling for precipitation extremes has been proposed
and refined in the past decades, allowing to address separately the contributions
from the thermodynamics, the dynamics and the microphysics. Theoretical constraints,
as well as remaining uncertainties, associated with each of these three contributions
to precipitation extremes, are discussed. Notably, although to leading order precipitation
extremes seem to follow the thermodynamic theoretical expectation in idealized
simulations, considerable uncertainty remains regarding the response of the dynamics
and of the microphysics to warming, and considerable departure from this theoretical
expectation is found in observations and in more realistic simulations. We also
emphasize key outstanding questions, in particular the response of mesoscale convective
organization to warming. Observations suggest that extreme rainfall often comes
from an organized system in very moist environments. Improved understanding of
the physical processes behind convective organization is needed in order to achieve
accurate extreme rainfall prediction in our current, and in a warming climate.

text: This study investigates the feedbacks between an interactive sea surface temperature
(SST) and the self‐aggregation of deep convective clouds, using a cloud‐resolving
model in nonrotating radiative‐convective equilibrium. The ocean is modeled as
one layer slab with a temporally fixed mean but spatially varying temperature.
We find that the interactive SST decelerates the aggregation and that the deceleration
is larger with a shallower slab, consistent with earlier studies. The surface
temperature anomaly in dry regions is positive at first, thus opposing the diverging
shallow circulation known to favor self‐aggregation, consistent with the slower
aggregation. But surprisingly, the driest columns then have a negative SST anomaly,
thus strengthening the diverging shallow circulation and favoring aggregation.
This diverging circulation out of dry regions is found to be well correlated with
the aggregation speed. It can be linked to a positive surface pressure anomaly
(PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling.
The latter cools and dries the boundary layer, thus increasing PSFC anomalies
through virtual effects and hydrostasy. Sensitivity experiments confirm the key
role played by boundary layer radiative cooling in determining PSFC anomalies
in dry regions, and thus the shallow diverging circulation and the aggregation
speed.

text: The couplings among clouds, convection, and circulation in trade-wind regimes
remain a fundamental puzzle that limits our ability to constrain future climate
change. Radiative heating plays an important role in these couplings. Here we
calculate the clear-sky radiative profiles from 2001 in-situ soundings (978 dropsondes
and 1023 radiosondes) collected during the EUREC4A field campaign, which took
place south and east of Barbados in January–February 2020. We describe the method
used to calculate these radiative profiles and present preliminary results sampling
variability at multiple scales, from the variability across all soundings to groupings
by diurnal cycle and mesoscale organization state, as well as individual soundings
associated with elevated moisture layers. This clear-sky radiative profiles data
set can provide important missing detail to what can be learned from calculations
based on passive remote sensing and help in investigating the role of radiation
in dynamic and thermodynamic variability in trade-wind regimes. All data are archived
and freely available for public access on AERIS (Albright et al. (2020), https://doi.org/10.25326/78).

text: 'Inversions are chromosomal rearrangements where the order of genes is reversed.
Inversions originate by mutation and can be under positive, negative or balancing
selection. Selective effects result from potential disruptive effects on meiosis,
gene disruption at inversion breakpoints and, importantly, the effects of inversions
as modifiers of recombination rate: Recombination is strongly reduced in individuals
heterozygous for an inversion, allowing for alleles at different loci to be inherited
as a ‘block’. This may lead to a selective advantage whenever it is favourable
to keep certain combinations of alleles associated, for example under local adaptation
with gene flow. Inversions can cover a considerable part of a chromosome and contain
numerous loci under different selection pressures, so that the resulting overall
effects may be complex. Empirical data from various systems show that inversions
may have a prominent role in local adaptation, speciation, parallel evolution,
the maintenance of polymorphism and sex chromosome evolution.'

text: Active navigation relies on effectively extracting information from the surrounding
environment, and often features the tracking of gradients of a relevant signal—such
as the concentration of molecules. Microfluidic networks of closed pathways pose
the challenge of determining the shortest exit pathway, which involves the proper
local decision-making at each bifurcating junction. Here, we focus on the basic
decision faced at a T-junction by a microscopic particle, which orients among
possible paths via its sensing of a diffusible substance's concentration. We study
experimentally the navigation of colloidal particles following concentration gradients
by diffusiophoresis. We treat the situation as a mean first passage time (MFPT)
problem that unveils the important role of a separatrix in the concentration field
to determine the statistics of path taking. Further, we use numerical experiments
to study different strategies, including biomimetic ones such as run and tumble
or Markovian chemotactic migration. The discontinuity in the MFPT at the junction
makes it remarkably difficult for microscopic agents to follow the shortest path,
irrespective of adopted navigation strategy. In contrast, increasing the size
of the sensing agents improves the efficiency of short-path taking by harvesting
information on a larger scale. It inspires the development of a run-and-whirl
dynamics that takes advantage of the mathematical properties of harmonic functions
to emulate particles beyond their own size.

text: Rhombic dodecahedron is a space filling polyhedron which represents the close
packing of spheres in 3D space and the Voronoi structures of the face centered
cubic (FCC) lattice. In this paper, we describe a new coordinate system where
every 3-integer coordinates grid point corresponds to a rhombic dodecahedron centroid.
In order to illustrate the interest of the new coordinate system, we propose the
characterization of 3D digital plane with its topological features, such as the
interrelation between the thickness of the digital plane and the separability
constraint we aim to obtain. We also present the characterization of 3D digital
lines and study it as the intersection of multiple digital planes. Characterization
of 3D digital sphere with relevant topological features is proposed as well along
with the 48-symmetry appearing in the new coordinate system.

text: We call a multigraph non-homotopic if it can be drawn in the plane in such
a way that no two edges connecting the same pair of vertices can be continuously
transformed into each other without passing through a vertex, and no loop can
be shrunk to its end-vertex in the same way. It is easy to see that a non-homotopic
multigraph on n>1 vertices can have arbitrarily many edges. We prove that the
number of crossings between the edges of a non-homotopic multigraph with n vertices
and m>4n edges is larger than cm2n for some constant c>0 , and that this
bound is tight up to a polylogarithmic factor. We also show that the lower bound
is not asymptotically sharp as n is fixed and m⟶∞ .

text: In 1989, Rota made the following conjecture. Given n bases B1,…,Bn in an n-dimensional
vector space V, one can always find n disjoint bases of V, each containing exactly
one element from each Bi (we call such bases transversal bases). Rota’s basis
conjecture remains wide open despite its apparent simplicity and the efforts of
many researchers (e.g., the conjecture was recently the subject of the collaborative
“Polymath” project). In this paper we prove that one can always find (1/2−o(1))n
disjoint transversal bases, improving on the previous best bound of Ω(n/logn).
Our results also apply to the more general setting of matroids.

text: An n-vertex graph is called C-Ramsey if it has no clique or independent set
of size Clogn. All known constructions of Ramsey graphs involve randomness in
an essential way, and there is an ongoing line of research towards showing that
in fact all Ramsey graphs must obey certain “richness” properties characteristic
of random graphs. Motivated by an old problem of Erd̋s and McKay, recently Narayanan,
Sahasrabudhe, and Tomon conjectured that for any fixed C, every n-vertex C-Ramsey
graph induces subgraphs of Θ(n2) different sizes. In this paper we prove this
conjecture.

text: It is a classical fact that for any ε>0, a random permutation of length n=(1+ε)k2/4
typically contains a monotone subsequence of length k. As a far-reaching generalization,
Alon conjectured that a random permutation of this same length n is typically
k-universal, meaning that it simultaneously contains every pattern of length k.
He also made the simple observation that for n=O(k2logk), a random length-n permutation
is typically k-universal. We make the first significant progress towards Alon's
conjecture by showing that n=2000k2loglogk suffices.

text: "Second-order information, in the form of Hessian- or Inverse-Hessian-vector
products, is a fundamental tool for solving optimization problems. Recently, there
has been significant interest in utilizing this information in the context of
deep\r\nneural networks; however, relatively little is known about the quality
of existing approximations in this context. Our work examines this question, identifies
issues with existing approaches, and proposes a method called WoodFisher to compute
a faithful and efficient estimate of the inverse Hessian. Our main application
is to neural network compression, where we build on the classic Optimal Brain
Damage/Surgeon framework. We demonstrate that WoodFisher significantly outperforms
popular state-of-the-art methods for oneshot pruning. Further, even when iterative,
gradual pruning is allowed, our method results in a gain in test accuracy over
the state-of-the-art approaches, for standard image classification datasets such
as ImageNet ILSVRC. We examine how our method can be extended to take into account
first-order information, as well as\r\nillustrate its ability to automatically
set layer-wise pruning thresholds and perform compression in the limited-data
regime. The code is available at the following link, https://github.com/IST-DASLab/WoodFisher."

text: Various kinds of data are routinely represented as discrete probability distributions.
Examples include text documents summarized by histograms of word occurrences and
images represented as histograms of oriented gradients. Viewing a discrete probability
distribution as a point in the standard simplex of the appropriate dimension,
we can understand collections of such objects in geometric and topological terms. Importantly,
instead of using the standard Euclidean distance, we look into dissimilarity measures
with information-theoretic justification, and we develop the theory needed for
applying topological data analysis in this setting. In doing so, we emphasize
constructions that enable the usage of existing computational topology software
in this context.

text: The ability to leverage large-scale hardware parallelism has been one of the
key enablers of the accelerated recent progress in machine learning. Consequently,
there has been considerable effort invested into developing efficient parallel
variants of classic machine learning algorithms. However, despite the wealth of
knowledge on parallelization, some classic machine learning algorithms often prove
hard to parallelize efficiently while maintaining convergence. In this paper,
we focus on efficient parallel algorithms for the key machine learning task of
inference on graphical models, in particular on the fundamental belief propagation
algorithm. We address the challenge of efficiently parallelizing this classic
paradigm by showing how to leverage scalable relaxed schedulers in this context.
We present an extensive empirical study, showing that our approach outperforms
previous parallel belief propagation implementations both in terms of scalability
and in terms of wall-clock convergence time, on a range of practical applications.

text: The visualization of data is indispensable in scientific research, from the
early stages when human insight forms to the final step of communicating results.
In computational physics, chemistry and materials science, it can be as simple
as making a scatter plot or as straightforward as looking through the snapshots
of atomic positions manually. However, as a result of the "big data" revolution,
these conventional approaches are often inadequate. The widespread adoption of
high-throughput computation for materials discovery and the associated community-wide
repositories have given rise to data sets that contain an enormous number of compounds
and atomic configurations. A typical data set contains thousands to millions of
atomic structures, along with a diverse range of properties such as formation
energies, band gaps, or bioactivities.It would thus be desirable to have a data-driven
and automated framework for visualizing and analyzing such structural data sets.
The key idea is to construct a low-dimensional representation of the data, which
facilitates navigation, reveals underlying patterns, and helps to identify data
points with unusual attributes. Such data-intensive maps, often employing machine
learning methods, are appearing more and more frequently in the literature. However,
to the wider community, it is not always transparent how these maps are made and
how they should be interpreted. Furthermore, while these maps undoubtedly serve
a decorative purpose in academic publications, it is not always apparent what
extra information can be garnered from reading or making them.This Account attempts
to answer such questions. We start with a concise summary of the theory of representing
chemical environments, followed by the introduction of a simple yet practical
conceptual approach for generating structure maps in a generic and automated manner.
Such analysis and mapping is made nearly effortless by employing the newly developed
software tool ASAP. To showcase the applicability to a wide variety of systems
in chemistry and materials science, we provide several illustrative examples,
including crystalline and amorphous materials, interfaces, and organic molecules.
In these examples, the maps not only help to sift through large data sets but
also reveal hidden patterns that could be easily missed using conventional analyses.The
explosion in the amount of computed information in chemistry and materials science
has made visualization into a science in itself. Not only have we benefited from
exploiting these visualization methods in previous works, we also believe that
the automated mapping of data sets will in turn stimulate further creativity and
exploration, as well as ultimately feed back into future advances in the respective
fields.

text: Predicting phase stabilities of crystal polymorphs is central to computational
materials science and chemistry. Such predictions are challenging because they
first require searching for potential energy minima and then performing arduous
free-energy calculations to account for entropic effects at finite temperatures.
Here, we develop a framework that facilitates such predictions by exploiting all
the information obtained from random searches of crystal structures. This framework
combines automated clustering, classification and visualisation of crystal structures
with machine-learning estimation of their enthalpy and entropy. We demonstrate
the framework on the technologically important system of TiO2, which has many
polymorphs, without relying on prior knowledge of known phases. We find a number
of new phases and predict the phase diagram and metastabilities of crystal polymorphs
at 1600 K, benchmarking the results against full free-energy calculations.

text: Water molecules can arrange into a liquid with complex hydrogen-bond networks
and at least 17 experimentally confirmed ice phases with enormous structural diversity.
It remains a puzzle how or whether this multitude of arrangements in different
phases of water are related. Here we investigate the structural similarities between
liquid water and a comprehensive set of 54 ice phases in simulations, by directly
comparing their local environments using general atomic descriptors, and also
by demonstrating that a machine-learning potential trained on liquid water alone
can predict the densities, lattice energies, and vibrational properties of the
ices. The finding that the local environments characterising the different ice
phases are found in water sheds light on the phase behavior of water, and rationalizes
the transferability of water models between different phases.

text: Game of Life is a simple and elegant model to study dynamical system over
networks. The model consists of a graph where every vertex has one of two types,
namely, dead or alive. A configuration is a mapping of the vertices to the types.
An update rule describes how the type of a vertex is updated given the types of
its neighbors. In every round, all vertices are updated synchronously, which leads
to a configuration update. While in general, Game of Life allows a broad range
of update rules, we focus on two simple families of update rules, namely, underpopulation
and overpopulation, that model several interesting dynamics studied in the literature.
In both settings, a dead vertex requires at least a desired number of live neighbors
to become alive. For underpopulation (resp., overpopulation), a live vertex requires
at least (resp. at most) a desired number of live neighbors to remain alive. We
study the basic computation problems, e.g., configuration reachability, for these
two families of rules. For underpopulation rules, we show that these problems
can be solved in polynomial time, whereas for overpopulation rules they are PSPACE-complete.

text: A regular language L of finite words is composite if there are regular languages
L₁,L₂,…,L_t such that L = ⋂_{i = 1}^t L_i and the index (number of states in a
minimal DFA) of every language L_i is strictly smaller than the index of L. Otherwise,
L is prime. Primality of regular languages was introduced and studied in [O. Kupferman
and J. Mosheiff, 2015], where the complexity of deciding the primality of the
language of a given DFA was left open, with a doubly-exponential gap between the
upper and lower bounds. We study primality for unary regular languages, namely
regular languages with a singleton alphabet. A unary language corresponds to a
subset of ℕ, making the study of unary prime languages closer to that of primality
in number theory. We show that the setting of languages is richer. In particular,
while every composite number is the product of two smaller numbers, the number
t of languages necessary to decompose a composite unary language induces a strict
hierarchy. In addition, a primality witness for a unary language L, namely a word
that is not in L but is in all products of languages that contain L and have an
index smaller than L’s, may be of exponential length. Still, we are able to characterize
compositionality by structural properties of a DFA for L, leading to a LogSpace
algorithm for primality checking of unary DFAs.

text: We prove some recent experimental observations of Dan Reznik concerning periodic
billiard orbits in ellipses. For example, the sum of cosines of the angles of
a periodic billiard polygon remains constant in the 1-parameter family of such
polygons (that exist due to the Poncelet porism). In our proofs, we use geometric
and complex analytic methods.

text: The brain vasculature supplies neurons with glucose and oxygen, but little
is known about how vascular plasticity contributes to brain function. Using longitudinal
in vivo imaging, we reported that a substantial proportion
of blood vessels in the adult brain sporadically occluded and regressed. Their
regression proceeded through sequential stages of blood-flow occlusion, endothelial
cell collapse, relocation or loss of pericytes, and retraction of glial endfeet.
Regressing vessels were found to be widespread in mouse, monkey and human brains.
Both brief occlusions of the middle cerebral artery and lipopolysaccharide-mediated
inflammation induced an increase of vessel regression. Blockage of leukocyte adhesion
to endothelial cells alleviated LPS-induced vessel regression. We further revealed
that blood vessel regression caused a reduction of neuronal activity due to a
dysfunction in mitochondrial metabolism and glutamate production. Our results
elucidate the mechanism of vessel regression and its role in neuronal function
in the adult brain.

text: A look at international activities on Open Science reveals a broad spectrum
from individual institutional policies to national action plans. The present Recommendations
for a National Open Science Strategy in Austria are based on these international
initiatives and present practical considerations for their coordinated implementation
with regard to strategic developments in research, technology and innovation (RTI)
in Austria until 2030. They are addressed to all relevant actors in the RTI system,
in particular to Research Performing Organisations, Research Funding Organisations,
Research Policy, memory institutions such as Libraries and Researchers. The recommendation
paper was developed from 2018 to 2020 by the OANA working group "Open Science
Strategy" and published for the first time in spring 2020 for a public consultation.
The now available final version of the recommendation document, which contains
feedback and comments from the consultation, is intended to provide an impetus
for further discussion and implementation of Open Science in Austria and serves
as a contribution and basis for a potential national Open Science Strategy in
Austria. The document builds on the diverse expertise of the authors (academia,
administration, library and archive, information technology, science policy, funding
system, etc.) and reflects their personal experiences and opinions.

Die vorliegenden Empfehlungen für eine nationale Open Science Strategie in Österreich
orientieren sich an diesen internationalen Initiativen und stellen praktische
Überlegungen für ihre koordinierte Implementierung im Hinblick auf strategische

dar. Dabei richten sie sich an alle relevanten Akteur*innen im FTI System, im
Besonderen an Forschungsstätten, Forschungsförderer, Forschungspolitik, Gedächtnisinstitutionen
wie Bibliotheken und Wissenschafter*innen. Das Empfehlungspapier wurde von 2018
bis 2020 von der OANA-Arbeitsgruppe "Open Science Strategie" entwickelt und im
Frühling 2020 das erste Mal für eine öffentliche Konsultation veröffentlicht.
Die nun vorliegende finale Version des Empfehlungsdokuments, die Feedback und
Kommentare aus der Konsultation enthält, soll ein Anstoß für die weitere Diskussion
und Umsetzung von Open Science in Österreich sein und als Beitrag und Grundlage
einer potentiellen nationalen Open Science Strategie in Österreich dienen. Das
Dokument baut auf der vielfältigen Expertise der Autor*innen auf (Wissenschaft,
Administration, Bibliothek und Archiv, Informationstechnologie, Wissenschaftspolitik,
Förderwesen etc.) und spiegelt deren persönliche Erfahrungen und Meinung wider.

text: "We develop algorithms and techniques to compute rigorous bounds for finite
pieces of orbits of the critical points, for intervals of parameter values, in
the quadratic family of one-dimensional maps fa(x)=a−x2. We illustrate the effectiveness
of our approach by constructing a dynamically defined partition \U0001D4AB of
the parameter interval Ω=[1.4,2] into almost 4×106 subintervals, for each of which
we compute to high precision the orbits of the critical points up to some time
N and other dynamically relevant quantities, several of which can vary greatly,
possibly spanning several orders of magnitude. We also subdivide \U0001D4AB into
a family \U0001D4AB+ of intervals, which we call stochastic intervals, and a family
\U0001D4AB− of intervals, which we call regular intervals. We numerically prove
that each interval ω∈\U0001D4AB+ has an escape time, which roughly means that
some iterate of the critical point taken over all the parameters in ω has considerable
width in the phase space. This suggests, in turn, that most parameters belonging
to the intervals in \U0001D4AB+ are stochastic and most parameters belonging to
the intervals in \U0001D4AB− are regular, thus the names. We prove that the intervals
in \U0001D4AB+ occupy almost 90% of the total measure of Ω. The software and the
data are freely available at http://www.pawelpilarczyk.com/quadr/, and a web page
is provided for carrying out the calculations. The ideas and procedures can be
easily generalized to apply to other parameterized families of dynamical systems."

text: Given l>2ν>2d≥4, we prove the persistence of a Cantor--family of KAM tori
of measure O(ε1/2−ν/l) for any non--degenerate nearly integrable Hamiltonian system
of class Cl(D×Td), where D⊂Rd is a bounded domain, provided that the size ε of
the perturbation is sufficiently small. This extends a result by D. Salamon in
\cite{salamon2004kolmogorov} according to which we do have the persistence of
a single KAM torus in the same framework. Moreover, it is well--known that, for
the persistence of a single torus, the regularity assumption can not be improved.

text: "Mosaic analysis with double markers (MADM) technology enables concomitant
fluorescent cell labeling and induction of uniparental chromosome disomy (UPD)
with single-cell resolution. In UPD, imprinted genes are either overexpressed
2-fold or are not expressed. Here, the MADM platform is utilized to probe imprinting
phenotypes at the transcriptional level. This protocol highlights major steps
for the generation and isolation of projection neurons and astrocytes with MADM-induced
UPD from mouse cerebral cortex for downstream single-cell and low-input sample
RNA-sequencing experiments.\r\n\r\nFor complete details on the use and execution

text: 'The fundamental and practical importance of particle stabilization has motivated
various characterization methods for studying polymer brushes on particle surfaces.
In this work, we show how one can perform sensitive measurements of neutral polymer
coating on colloidal particles using a commercial zetameter and salt solutions.
By systematically varying the Debye length, we study the mobility of the polymer-coated
particles in an applied electric field and show that the electrophoretic mobility
of polymer-coated particles normalized by the mobility of non-coated particles
is entirely controlled by the polymer brush and independent of the native surface
charge, here controlled with pH, or the surface–ion interaction. Our result is
rationalized with a simple hydrodynamic model, allowing for the estimation of
characteristics of the polymer coating: the brush length L, and the Brinkman length
ξ, determined by its resistance to flows. We demonstrate that the Debye layer
provides a convenient and faithful probe to the characterization of polymer coatings
on particles. Because the method simply relies on a conventional zetameter, it
is widely accessible and offers a practical tool to rapidly probe neutral polymer
brushes, an asset in the development and utilization of polymer-coated colloidal
particles.'

text: In the quest for alternate and efficient electrode materials, ternary metal
electrocatalysts (TMEs), part of the perovskite family, were synthesized and tested
for methanol electro-oxidation in alkaline media. La0.5Ca0.5MO3 (M = Ni, Co, or
Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that
the perovskite crystal structure possesses characteristic sharp and crystalline
peaks for all synthesized ternary electrocatalysts. The average particle size
calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO)
> La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as
prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The
qualitative and quantitative analysis revealed the presence of La, Ca and Co in
parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82%
respectively. The particle size distribution was homogenous, as determined by
scanning electron and transmission electron microscopes. The electrocatalytic
activity of the synthesized ternary electrocatalysts was studied electrochemically
by cyclic voltammetry. The calculated diffusion coefficient values showed that
electrode surface of LCNO and LCCO have limited efficiency for diffusion related
phenomenon. The heterogeneous rate constants inferred better electrode kinetics
of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic
peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V,
respectively. Methanol electro-oxidation was found minimal in case of LCMO sample.
We have observed that Co substitution at B-site of perovskite electrode materials
attains better electrochemical properties, thus in relation with reported literature.

text: Gadolinium silicide (Gd5Si4) nanoparticles are an interesting class of materials
due to their high magnetization, low Curie temperature, low toxicity in biological
environments and their multifunctional properties. We report the magnetic and
magnetothermal properties of gadolinium silicide (Gd5Si4) nanoparticles prepared
by surfactant-assisted ball milling of arc melted bulk ingots of the compound.
Using different milling times and speeds, a wide range of crystallite sizes (13–43
nm) could be produced and a reduction in Curie temperature (TC) from 340 K to
317 K was achieved, making these nanoparticles suitable for self-controlled magnetic
hyperthermia applications. The magnetothermal effect was measured in applied AC
magnetic fields of amplitude 164–239 Oe and frequencies 163–519 kHz. All particles
showed magnetic heating with a strong dependence of the specific absorption rate
(SAR) on the average crystallite size. The highest SAR of 3.7 W g−1 was measured
for 43 nm sized nanoparticles of Gd5Si4. The high SAR and low TC, (within the
therapeutic range for magnetothermal therapy) makes the Gd5Si4 behave like self-regulating
heat switches that would be suitable for self-controlled magnetic hyperthermia
applications after biocompatibility and cytotoxicity tests.

text: 'We introduce LRT-NG, a set of techniques and an associated toolset that computes
a reachtube (an over-approximation of the set of reachable states over a given
time horizon) of a nonlinear dynamical system. LRT-NG significantly advances the
state-of-the-art Langrangian Reachability and its associated tool LRT. From a
theoretical perspective, LRT-NG is superior to LRT in three ways. First, it uses
for the first time an analytically computed metric for the propagated ball which
is proven to minimize the ball’s volume. We emphasize that the metric computation
is the centerpiece of all bloating-based techniques. Secondly, it computes the
next reachset as the intersection of two balls: one based on the Cartesian metric
and the other on the new metric. While the two metrics were previously considered
opposing approaches, their joint use considerably tightens the reachtubes. Thirdly,
it avoids the "wrapping effect" associated with the validated integration of the
center of the reachset, by optimally absorbing the interval approximation in the
radius of the next ball. From a tool-development perspective, LRT-NG is superior
to LRT in two ways. First, it is a standalone tool that no longer relies on CAPD.
This required the implementation of the Lohner method and a Runge-Kutta time-propagation
method. Secondly, it has an improved interface, allowing the input model and initial
conditions to be provided as external input files. Our experiments on a comprehensive
set of benchmarks, including two Neural ODEs, demonstrates LRT-NG’s superior performance
compared to LRT, CAPD, and Flow*.'

text: We investigate the role of a warm sea surface temperature (SST) anomaly (hot
spot of typically 3 to 5 K) on the aggregation of convection using cloud-resolving
simulations in a nonrotating framework. It is well known that SST gradients can
spatially organize convection. Even with uniform SST, the spontaneous self-aggregation
of convection is possible above a critical SST (here 295 K), arising mainly from
radiative feedbacks. We investigate how a circular hot spot helps organize convection,
and how self-aggregation feedbacks modulate this organization. The hot spot significantly
accelerates aggregation, particularly for warmer/larger hot spots, and extends
the range of SSTs for which aggregation occurs; however, at cold SST (290 K) the
aggregated cluster disaggregates if we remove the hot spot. A large convective
instability over the hot spot leads to stronger convection and generates a large-scale
circulation which forces the subsidence drying outside the hot spot. Indeed, convection
over the hot spot brings the atmosphere toward a warmer temperature. The warmer
temperatures are imprinted over the whole domain by gravity waves and subsidence
warming. The initial transient warming and concomitant subsidence drying suppress
convection outside the hot spot, thus driving the aggregation. The hot-spot-induced
large-scale circulation can enforce the aggregation even without radiative feedbacks
for hot spots sufficiently large/warm. The strength of the large-scale circulation,
which defines the speed of aggregation, is a function of the hot spot fractional
area. At equilibrium, once the aggregation is well established, the moist convective
region with upward midtropospheric motion, centered over the hot spot, has an
area surprisingly independent of the hot spot size.

text: We see them in our everyday lives. They make skies and sunsets even more beautiful,
inspiring painters all over the world. But what are clouds? What are the physical
processes occurring within a cloud? Do they all look alike, or are there different
types of clouds? Why? Beyond our small human scale, how are clouds distributed
at large, planetary scales? How do they couple and interact with the large-scale
circulation of the atmosphere? What do the physics of cloud formation tell us
about the hydrological cycle, including mean and extreme precipitation, in our
current climate and in a warming world? What role do they play in the global energetics
of the planet, for instance by reflecting the incoming shortwave radiation from
the Sun, and by reducing the outgoing longwave radiation to space, because of
their high altitudes and thus cold temperatures? These are the questions that
will be addressed in these five lectures.

text: The goal of this study is twofold. First, we aim at developing a simple model
as an interpretative framework for the water vapor isotopic variations in the
tropical troposphere over the ocean. We use large-eddy simulations to justify
the underlying assumptions of this simple model, to constrain its input parameters
and to evaluate its results. Second, we aim at interpreting the depletion of the
water vapor isotopic composition in the lower and mid-troposphere as precipitation
increases, which is a salient feature in tropical oceanic observations. This feature
constitutes a stringent test on the relevance of our interpretative framework.
Previous studies, based on observations or on models with parameterized convection,
have highlighted the roles of deep convective and meso-scale downdrafts, rain
evaporation, rain-vapor diffusive exchanges and mixing processes. The interpretative
framework that we develop is a two-column model representing the net ascent in
clouds and the net descent in the environment. We show that the mechanisms for
depleting the troposphere when precipitation rate increases all stem from the
higher tropospheric relative humidity. First, when the relative humidity is larger,
less snow sublimates before melting and a smaller fraction of rain evaporates.
Both effects lead to more depleted rain evaporation and eventually more depleted
water vapor. This mechanism dominates in regimes of large-scale ascent. Second,
the entrainment of dry air into clouds reduces the vertical isotopic gradient
and limits the depletion of tropospheric water vapor. This mechanism dominates
in regimes of large-scale descent.

text: 'Bending-active structures are able to efficiently produce complex curved
shapes from flat panels. The desired deformation of the panels derives from the
proper selection of their elastic properties. Optimized panels, called FlexMaps,
are designed such that, once they are bent and assembled, the resulting static
equilibrium configuration matches a desired input 3D shape. The FlexMaps elastic
properties are controlled by locally varying spiraling geometric mesostructures,
which are optimized in size and shape to match specific bending requests, namely
the global curvature of the target shape. The design pipeline starts from a quad
mesh representing the input 3D shape, which defines the edge size and the total
amount of spirals: every quad will embed one spiral. Then, an optimization algorithm
tunes the geometry of the spirals by using a simplified pre-computed rod model.
This rod model is derived from a non-linear regression algorithm which approximates
the non-linear behavior of solid FEM spiral models subject to hundreds of load
combinations. This innovative pipeline has been applied to the project of a lightweight
plywood pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted
arch that fits a bounding box of 3.90x3.96x3.25 meters. This case study serves
to test the applicability of this methodology at the architectural scale. The
structure is validated via FE analyses and the fabrication of the full scale prototype.'

text: "Recent works have shown that gradient descent can find a global minimum for
over-parameterized neural networks where the widths of all the hidden layers scale
polynomially with N (N being the number of training samples). In this paper, we
prove that, for deep networks, a single layer of width N following the input layer
suffices to ensure a similar guarantee. In particular, all the remaining layers
are allowed to have constant widths, and form a pyramidal topology. We show an
application of our result to the widely used LeCun’s initialization and obtain
an over-parameterization requirement for the single wide layer of order N2.\r\n"

text: 'Optimizing convolutional neural networks for fast inference has recently
become an extremely active area of research. One of the go-to solutions in this
context is weight pruning, which aims to reduce computational and memory footprint
by removing large subsets of the connections in a neural network. Surprisingly,
much less attention has been given to exploiting sparsity in the activation maps,
which tend to be naturally sparse in many settings thanks to the structure of
rectified linear (ReLU) activation functions. In this paper, we present an in-depth
analysis of methods for maximizing the sparsity of the activations in a trained
neural network, and show that, when coupled with an efficient sparse-input convolution
algorithm, we can leverage this sparsity for significant performance gains. To
induce highly sparse activation maps without accuracy loss, we introduce a new
regularization technique, coupled with a new threshold-based sparsification method
based on a parameterized activation function called Forced-Activation-Threshold
Rectified Linear Unit (FATReLU). We examine the impact of our methods on popular
image classification models, showing that most architectures can adapt to significantly
sparser activation maps without any accuracy loss. Our second contribution is
showing that these these compression gains can be translated into inference speedups:
we provide a new algorithm to enable fast convolution operations over networks
with sparse activations, and show that it can enable significant speedups for
end-to-end inference on a range of popular models on the large-scale ImageNet
image classification task on modern Intel CPUs, with little or no retraining cost. '

text: DNA methylation and histone H1 mediate transcriptional silencing of genes
and transposable elements, but how they interact is unclear. In plants and animals
with mosaic genomic methylation, functionally mysterious methylation is also common
within constitutively active housekeeping genes. Here, we show that H1 is enriched
in methylated sequences, including genes, of Arabidopsis thaliana, yet this enrichment
is independent of DNA methylation. Loss of H1 disperses heterochromatin, globally
alters nucleosome organization, and activates H1-bound genes, but only weakly
de-represses transposable elements. However, H1 loss strongly activates transposable
elements hypomethylated through mutation of DNA methyltransferase MET1. Hypomethylation
of genes also activates antisense transcription, which is modestly enhanced by
H1 loss. Our results demonstrate that H1 and DNA methylation jointly maintain
transcriptional homeostasis by silencing transposable elements and aberrant intragenic
transcripts. Such functionality plausibly explains why DNA methylation, a well-known
mutagen, has been maintained within coding sequences of crucial plant and animal
genes.

text: How long a monotone path can one always find in any edge-ordering of the complete
graph Kn? This appealing question was first asked by Chvátal and Komlós in 1971,
and has since attracted the attention of many researchers, inspiring a variety
of related problems. The prevailing conjecture is that one can always find a monotone
path of linear length, but until now the best known lower bound was n2/3-o(1).
In this paper we almost close this gap, proving that any edge-ordering of the
complete graph contains a monotone path of length n1-o(1).

text: The problem of finding dense induced bipartite subgraphs in H-free graphs
has a long history, and was posed 30 years ago by Erdős, Faudree, Pach and Spencer.
In this paper, we obtain several results in this direction. First we prove that
any H-free graph with minimum degree at least d contains an induced bipartite
subgraph of minimum degree at least cH log d/log log d, thus nearly confirming
one and proving another conjecture of Esperet, Kang and Thomassé. Complementing
this result, we further obtain optimal bounds for this problem in the case of
dense triangle-free graphs, and we also answer a question of Erdœs, Janson, Łuczak
and Spencer.

text: "We show that for any \U0001D45B divisible by 3, almost all order- \U0001D45B
\ Steiner triple systems have a perfect matching (also known as a parallel class
or resolution class). In fact, we prove a general upper bound on the number of
perfect matchings in a Steiner triple system and show that almost all Steiner
triple systems essentially attain this maximum. We accomplish this via a general
theorem comparing a uniformly random Steiner triple system to the outcome of the
triangle removal process, which we hope will be useful for other problems. Our
methods can also be adapted to other types of designs; for example, we sketch
a proof of the theorem that almost all Latin squares have transversals."

text: Macroscopic models of nucleation provide powerful tools for understanding
activated phase transition processes. These models do not provide atomistic insights
and can thus sometimes lack material-specific descriptions. Here, we provide a
comprehensive framework for constructing a continuum picture from an atomistic
simulation of homogeneous nucleation. We use this framework to determine the equilibrium
shape of the solid nucleus that forms inside bulk liquid for a Lennard-Jones potential.
From this shape, we then extract the anisotropy of the solid-liquid interfacial
free energy, by performing a reverse Wulff construction in the space of spherical
harmonic expansions. We find that the shape of the nucleus is nearly spherical
and that its anisotropy can be perfectly described using classical models.

text: Equilibrium molecular dynamics simulations, in combination with the Green-Kubo
(GK) method, have been extensively used to compute the thermal conductivity of
liquids. However, the GK method relies on an ambiguous definition of the microscopic
heat flux, which depends on how one chooses to distribute energies over atoms.
This ambiguity makes it problematic to employ the GK method for systems with nonpairwise
interactions. In this work, we show that the hydrodynamic description of thermally
driven density fluctuations can be used to obtain the thermal conductivity of
a bulk fluid unambiguously, thereby bypassing the need to define the heat flux.
We verify that, for a model fluid with only pairwise interactions, our method
yields estimates of thermal conductivity consistent with the GK approach. We apply
our approach to compute the thermal conductivity of a nonpairwise additive water
model at supercritical conditions, and of a liquid hydrogen system described by
a machine-learning interatomic potential, at 33 GPa and 2000 K.

text: Hydrogen, the simplest and most abundant element in the Universe, develops
a remarkably complex behaviour upon compression^1. Since Wigner predicted the
dissociation and metallization of solid hydrogen at megabar pressures almost a
century ago^2, several efforts have been made to explain the many unusual properties
of dense hydrogen, including a rich and poorly understood solid polymorphism^1,3-5,
an anomalous melting line6 and the possible transition to a superconducting state^7.
Experiments at such extreme conditions are challenging and often lead to hard-to-interpret
and controversial observations, whereas theoretical investigations are constrained
by the huge computational cost of sufficiently accurate quantum mechanical calculations.
Here we present a theoretical study of the phase diagram of dense hydrogen that
uses machine learning to 'learn' potential-energy surfaces and interatomic forces
from reference calculations and then predict them at low computational cost, overcoming
length- and timescale limitations. We reproduce both the re-entrant melting behaviour
and the polymorphism of the solid phase. Simulations using our machine-learning-based
potentials provide evidence for a continuous molecular-to-atomic transition in
the liquid, with no first-order transition observed above the melting line. This
suggests a smooth transition between insulating and metallic layers in giant gas
planets, and reconciles existing discrepancies between experiments as a manifestation
of supercritical behaviour.

text: Obtaining detailed information about high mountain snowpacks is often limited
by insufficient ground-based observations and uncertainty in the (re)distribution
of solid precipitation. We utilize high-resolution optical images from Pléiades
satellites to generate a snow depth map, at a spatial resolution of 4 m, for a
high mountain catchment of central Chile. Results are negatively biased (median
difference of −0.22 m) when compared against observations from a terrestrial Light
Detection And Ranging scan, though replicate general snow depth variability well.
Additionally, the Pléiades dataset is subject to data gaps (17% of total pixels),
negative values for shallow snow (12%), and noise on slopes >40–50° (2%). We correct
and filter the Pléiades snow depths using surface classification techniques of
snow-free areas and a random forest model for data gap filling. Snow depths (with
an estimated error of ~0.36 m) average 1.66 m and relate well to topographical
parameters such as elevation and northness in a similar way to previous studies.
However, estimations of snow depth based upon topography (TOPO) or physically
based modeling (DBSM) cannot resolve localized processes (i.e., avalanching or
wind scouring) that are detected by Pléiades, even when forced with locally calibrated
data. Comparing these alternative model approaches to corrected Pléiades snow
depths reveals total snow volume differences between −28% (DBSM) and +54% (TOPO)
for the catchment and large differences across most elevation bands. Pléiades
represents an important contribution to understanding snow accumulation at sparsely
monitored catchments, though ideally requires a careful systematic validation
procedure to identify catchment-scale biases and errors in the snow depth derivation.

text: Information about end-of-winter spatial distribution of snow depth is important
for seasonal forecasts of spring/summer streamflow in high-mountain regions. Nevertheless,
such information typically relies upon extrapolation from a sparse network of
observations at low elevations. Here, we test the potential of high-resolution
snow depth data derived from optical stereophotogrammetry of Pléiades satellites
for improving the representation of snow depth initial conditions (SDICs) in a
glacio-hydrological model and assess potential improvements in the skill of snowmelt
and streamflow simulations in a high-elevation Andean catchment. We calibrate
model parameters controlling glacier mass balance and snow cover evolution using
ground-based and satellite observations, and consider the relative importance
of accurate estimates of SDICs compared to model parameters and forcings. We find
that Pléiades SDICs improve the simulation of snow-covered area, glacier mass
balance, and monthly streamflow compared to alternative SDICs based upon extrapolation
of meteorological variables or statistical methods to estimate SDICs based upon
topography. Model simulations are found to be sensitive to SDICs in the early
spring (up to 48% variability in modeled streamflow compared to the best estimate
model), and to temperature gradients in all months that control albedo and melt
rates over a large elevation range (>2,400 m). As such, appropriately characterizing
the distribution of total snow volume with elevation is important for reproducing
total streamflow and the proportions of snowmelt. Therefore, optical stereo-photogrammetry
offers an advantage for obtaining SDICs that aid both the timing and magnitude
of streamflow simulations, process representation (e.g., snow cover evolution)
and has the potential for large spatial domains.

text: As glaciers adjust their size in response to climate variations, long-term
changes in meltwater production can be expected, affecting the local availability
of water resources. We investigate glacier runoff in the period 1955–2016 in the
Maipo River basin (4843 km2, 33.0–34.3∘ S, 69.8–70.5∘ W), in the semiarid Andes
of Chile. The basin contains more than 800 glaciers, which cover 378 km2 in total
(inventoried in 2000). We model the mass balance and runoff contribution of 26
glaciers with the physically oriented and fully distributed TOPKAPI (Topographic
Kinematic Approximation and Integration)-ETH glacio-hydrological model and extrapolate
the results to the entire basin. TOPKAPI-ETH is run at a daily time step using
several glaciological and meteorological datasets, and its results are evaluated
against streamflow records, remotely sensed snow cover, and geodetic mass balances
for the periods 1955–2000 and 2000–2013. Results show that in 1955–2016 glacier
mass balance had a general decreasing trend as a basin average but also had differences
between the main sub-catchments. Glacier volume decreased by one-fifth (from 18.6±4.5
to 14.9±2.9 km3). Runoff from the initially glacierized areas was 177±25 mm yr−1
(16±7 % of the total contributions to the basin), but it shows a decreasing sequence
of maxima, which can be linked to the interplay between a decrease in precipitation
since the 1980s and the reduction of ice melt. Glaciers in the Maipo River basin
will continue retreating because they are not in equilibrium with the current
climate. In a hypothetical constant climate scenario, glacier volume would reduce
to 81±38 % of the year 2000 volume, and glacier runoff would be 78±30 % of the
1955–2016 average. This would considerably decrease the drought mitigation capacity
of the basin.

text: We examine the spatial patterns of near-surface air temperature (Ta) over
a melting glacier using a multi-annual dataset from McCall Glacier, Alaska. The
dataset consists of a 10-year (2005–2014) meteorological record along the glacier
centreline up to an upper glacier cirque, spanning an elevation difference of
900 m. We test the validity of on-glacier linear lapse rates, and a model that
calculates Ta based on the influence of katabatic winds and other heat sources
along the glacier flow line. During the coldest hours of each summer (10% of time),
average lapse rates across the entire glacier range from −4.7 to −6.7°C km−1,
with a strong relationship between Ta and elevation (R2 > 0.7). During warm conditions,
Ta shows more complex, non-linear patterns that are better explained by the flow
line-dependent model, reducing errors by up to 0.5°C compared with linear lapse
rates, although more uncertainty might be associated with these observations due
to occasionally poor sensor ventilation. We conclude that Ta spatial distribution
can vary significantly from year to year, and from one glacier section to another.
Importantly, extrapolations using linear lapse rates from the ablation zone might
lead to large underestimations of Ta on the upper glacier areas.

text: The seasonal dynamic changes of Tibetan glaciers have seen little prior investigation,
despite the increase in geodetic studies of multi-year changes. This study compares
seasonal glacier dynamics (“cold” and “warm” seasons) in the ablation zone of
Parlung No. 4 Glacier, a temperate glacier in the monsoon-influenced southeastern
Tibetan Plateau, by using repeat unpiloted aerial vehicle (UAV) surveys combined
with Structure-from-Motion (SfM) photogrammetry and ground stake measurements.
Our results showed that the surveyed ablation zone had a mean change of −2.7 m
of ice surface elevation during the period of September 2018 to October 2019 but
is characterized by significant seasonal cyclic variations with ice surface elevation
lifting (+2.0 m) in the cold season (September 2018 to June 2019) but lowering
(−4.7 m) in the warm season (June 2019 to October 2019). Over an annual timescale,
surface lowering was greatly suppressed by the resupply of ice from the glacier’s
accumulation area—the annual emergence velocity compensates for about 55% of surface
ablation in our study area. Cold season emergence velocities (3.0 ± 1.2 m) were
~5-times larger than those observed in the warm season (0.6 ± 1.0 m). Distinct
spring precipitation patterns may contribute to these distinct seasonal signals.
Such seasonal dynamic conditions are possibly critical for different glacier responses
to climate change in this region of the Tibetan Plateau, and perhaps further afield.

text: Mountains are the water towers of the world, supplying a substantial part
of both natural and anthropogenic water demands1,2. They are highly sensitive
and prone to climate change3,4, yet their importance and vulnerability have not
been quantified at the global scale. Here we present a global water tower index
(WTI), which ranks all water towers in terms of their water-supplying role and
the downstream dependence of ecosystems and society. For each water tower, we
assess its vulnerability related to water stress, governance, hydropolitical tension
and future climatic and socio-economic changes. We conclude that the most important
(highest WTI) water towers are also among the most vulnerable, and that climatic
and socio-economic changes will affect them profoundly. This could negatively

text: 'Rock debris can accumulate on glacier surfaces and dramatically reduce glacier
melt. The structure of a debris cover is unique to each glacier and sensitive
to climate. Despite this, debris cover has been omitted from global glacier models
and forecasts of their response to a changing climate. Fundamental to resolving
these omissions is a global map of debris cover and an estimate of its future
spatial evolution. Here we use Landsat imagery and a detailed correction to the
Randolph Glacier Inventory to show that 7.3% of mountain glacier area is debris
covered and over half of Earth’s debris is concentrated in three regions: Alaska
(38.6% of total debris-covered area), Southwest Asia (12.6%) and Greenland (12.0%).
We use a set of new metrics, which include stage, the current position of a glacier
on its trajectory towards reaching its spatial carrying capacity of debris cover,
to quantify the state of glaciers. Debris cover is present on 44% of Earth’s glaciers
and prominent (>1.0 km2) on 15%. Of Earth’s glaciers, 20% have a substantial percentage
of debris cover for which the net stage is 36% and the bulk of individual glaciers
have evolved beyond an optimal moraine configuration favourable for debris-cover
expansion. Use of this dataset in global-scale models will enable improved estimates
of melt over 10.6% of the global glacier domain.'

text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
motivated alternative to backpropagation (BP), by substituting the computations
that are unrealistic to be implemented in physical brains. While FA algorithms
have been shown to work well in practice, there is a lack of rigorous theory proofing
their learning capabilities. Here we introduce the first feedback alignment algorithm
with provable learning guarantees. In contrast to existing work, we do not require
any assumption about the size or depth of the network except that it has a single
output neuron, i.e., such as for binary classification tasks. We show that our
FA algorithm can deliver its theoretical promises in practice, surpassing the
learning performance of existing FA methods and matching backpropagation in binary
classification tasks. Finally, we demonstrate the limits of our FA variant when
the number of output neurons grows beyond a certain quantity.

text: "A natural approach to generative modeling of videos is to represent them
as a composition of moving objects. Recent works model a set of 2D sprites over
a slowly-varying background, but without considering the underlying 3D scene that\r\ngives
rise to them. We instead propose to model a video as the view seen while moving
through a scene with multiple 3D objects and a 3D background. Our model is trained
from monocular videos without any supervision, yet learns to\r\ngenerate coherent
3D scenes containing several moving objects. We conduct detailed experiments on
two datasets, going beyond the visual complexity supported by state-of-the-art
generative approaches. We evaluate our method on\r\ndepth-prediction and 3D object
detection---tasks which cannot be addressed by those earlier works---and show
it out-performs them even on 2D instance segmentation and tracking."

text: Molecular mechanisms enabling the switching and maintenance of epigenetic
states are not fully understood. Distinct histone modifications are often associated
with ON/OFF epigenetic states, but how these states are stably maintained through
DNA replication, yet in certain situations switch from one to another remains
unclear. Here, we address this problem through identification of Arabidopsis INCURVATA11
(ICU11) as a Polycomb Repressive Complex 2 accessory protein. ICU11 robustly immunoprecipitated
in vivo with PRC2 core components and the accessory proteins, EMBRYONIC FLOWER
1 (EMF1), LIKE HETEROCHROMATIN PROTEIN1 (LHP1), and TELOMERE_REPEAT_BINDING FACTORS
(TRBs). ICU11 encodes a 2-oxoglutarate-dependent dioxygenase, an activity associated
with histone demethylation in other organisms, and mutant plants show defects
in multiple aspects of the Arabidopsis epigenome. To investigate its primary molecular
function we identified the Arabidopsis FLOWERING LOCUS C (FLC) as a direct target
and found icu11 disrupted the cold-induced, Polycomb-mediated silencing underlying
vernalization. icu11 prevented reduction in H3K36me3 levels normally seen during
the early cold phase, supporting a role for ICU11 in H3K36me3 demethylation. This
was coincident with an attenuation of H3K27me3 at the internal nucleation site
in FLC, and reduction in H3K27me3 levels across the body of the gene after plants
were returned to the warm. Thus, ICU11 is required for the cold-induced epigenetic
switching between the mutually exclusive chromatin states at FLC, from the active
H3K36me3 state to the silenced H3K27me3 state. These data support the importance
of physical coupling of histone modification activities to promote epigenetic
switching between opposing chromatin states.

text: Meiotic crossovers (COs) are important for reshuffling genetic information
between homologous chromosomes and they are essential for their correct segregation.
COs are unevenly distributed along chromosomes and the underlying mechanisms controlling
CO localization are not well understood. We previously showed that meiotic COs
are mis-localized in the absence of AXR1, an enzyme involved in the neddylation/rubylation
protein modification pathway in Arabidopsis thaliana. Here, we report that in
axr1-/-, male meiocytes show a strong defect in chromosome pairing whereas the
formation of the telomere bouquet is not affected. COs are also redistributed
towards subtelomeric chromosomal ends where they frequently form clusters, in
contrast to large central regions depleted in recombination. The CO suppressed
regions correlate with DNA hypermethylation of transposable elements (TEs) in
the CHH context in axr1-/- meiocytes. Through examining somatic methylomes, we
found axr1-/- affects DNA methylation in a plant, causing hypermethylation in
all sequence contexts (CG, CHG and CHH) in TEs. Impairment of the main pathways
involved in DNA methylation is epistatic over axr1-/- for DNA methylation in somatic
cells but does not restore regular chromosome segregation during meiosis. Collectively,
our findings reveal that the neddylation pathway not only regulates hormonal perception
and CO distribution but is also, directly or indirectly, a major limiting pathway
of TE DNA methylation in somatic cells.

text: Let be a sequence of points on an elliptic curve defined over a number field
K. In this paper, we study the denominators of the x-coordinates of this sequence.
We prove that, if Q is a torsion point of prime order, then for n large enough
there always exists a primitive divisor. Later on, we show the link between the
study of the primitive divisors and a Lang-Trotter conjecture. Indeed, given two
points P and Q on the elliptic curve, we prove a lower bound for the number of
primes p such that P is in the orbit of Q modulo p.

text: "We investigate the structural similarities between liquid water and 53 ices,
including 20 known crystalline phases. We base such similarity comparison on the
local environments that consist of atoms within a certain cutoff radius of a central
atom. We reveal that liquid water explores the local environments of the diverse
ice phases, by directly comparing the environments in these phases using general
atomic descriptors, and also by demonstrating that a machine-learning potential
trained on liquid water alone can predict the densities, the lattice energies,
and vibrational properties of the\r\nices. The finding that the local environments
characterising the different ice phases are found in water sheds light on water
phase behaviors, and rationalizes the transferability of water models between
different phases."

text: Desorption electrospray ionization (DESI), easy ambient sonic-spray ionization
(EASI) and low-temperature plasma (LTP) ionization are powerful ambient ionization
techniques for mass spectrometry. However, every single method has its limitation
in terms of polarity and molecular weight of analyte molecules. After the miniaturization
of every possible component of the different ion sources, we finally were able
to embed two emitters and an ion transfer tubing into a small, hand-held device.
The pen-like interface is connected to the mass spectrometer and a separate control
unit via a bundle of flexible tubing and cables. The novel device allows the user
to ionize an extended range of chemicals by simple switching between DESI, voltage-free
EASI, or LTP ionization as well as to freely move the interface over a surface
of interest. A mini camera, which is mounted on the tip of the pen, magnifies
the desorption area and enables a simple positioning of the pen. The interface
was successfully tested using different types of chemicals, pharmaceuticals, and
real life samples. Moreover, the combination of optical data from the camera module
and chemical data obtained by mass analysis facilitates a novel type of imaging
mass spectrometry, which we name “interactive mass spectrometry imaging (IMSI)”.

text: 'Linear tetrapyrroles, called phyllobilins, are obtained as major catabolites
upon chlorophyll degradation. Primarily, colorless phylloleucobilins featuring
four deconjugated pyrrole units were identified. Their yellow counterparts, phylloxanthobilins,
were discovered more recently. Although the two catabolites differ only by one
double bond, physicochemical properties are very distinct. Moreover, the presence
of the double bond seems to enhance physiologically relevant bioactivities: in
contrast to phylloleucobilin, we identified a potent anti-proliferative activity
for a phylloxanthobilin, and show that this natural product induces apoptotic
cell death and a cell cycle arrest in cancer cells. Interestingly, upon modifying
inactive phylloleucobilin by esterification, an anti-proliferative activity can
be observed that increases with the chain lengths of the alkyl esters. We provide
first evidence for anti-cancer activity of phyllobilins, report a novel plant
source for a phylloxanthobilin, and by using paper spray MS, show that these bioactive
yellow chlorophyll catabolites are more prevalent in Nature than previously assumed.'

text: Quantization converts neural networks into low-bit fixed-point computations
which can be carried out by efficient integer-only hardware, and is standard practice
for the deployment of neural networks on real-time embedded devices. However,
like their real-numbered counterpart, quantized networks are not immune to malicious
misclassification caused by adversarial attacks. We investigate how quantization
affects a network’s robustness to adversarial attacks, which is a formal verification
question. We show that neither robustness nor non-robustness are monotonic with
changing the number of bits for the representation and, also, neither are preserved
by quantization from a real-numbered network. For this reason, we introduce a
verification method for quantized neural networks which, using SMT solving over
bit-vectors, accounts for their exact, bit-precise semantics. We built a tool
and analyzed the effect of quantization on a classifier for the MNIST dataset.
We demonstrate that, compared to our method, existing methods for the analysis
of real-numbered networks often derive false conclusions about their quantizations,
both when determining robustness and when detecting attacks, and that existing
methods for quantized networks often miss attacks. Furthermore, we applied our
method beyond robustness, showing how the number of bits in quantization enlarges
the gender bias of a predictor for students’ grades.
