text: "We build upon the recent papers by Weinstein and Yu (FOCS'16), Larsen (FOCS'12),
and Clifford et al. (FOCS'15) to present a general framework that gives amortized
lower bounds on the update and query times of dynamic data structures. Using our
framework, we present two concrete results.\r\n(1) For the dynamic polynomial
evaluation problem, where the polynomial is defined over a finite field of size
n1+Ω(1) and has degree n, any dynamic data structure must either have an amortized
update time of Ω((lgn/lglgn)2) or an amortized query time of Ω((lgn/lglgn)2).\r\n(2)
For the dynamic online matrix vector multiplication problem, where we get an n×n
matrix whose entires are drawn from a finite field of size nΘ(1), any dynamic
data structure must either have an amortized update time of Ω((lgn/lglgn)2) or
an amortized query time of Ω(n⋅(lgn/lglgn)2).\r\nFor these two problems, the previous
works by Larsen (FOCS'12) and Clifford et al. (FOCS'15) gave the same lower bounds,
but only for worst case update and query times. Our bounds match the highest unconditional
lower bounds known till date for any dynamic problem in the cell-probe model."

text: Cross-coupling reactions mediated by dual nickel/photocatalysis are synthetically
attractive but rely mainly on expensive, non-recyclable noble-metal complexes
as photocatalysts. Heterogeneous semiconductors, which are commonly used for artificial
photosynthesis and wastewater treatment, are a sustainable alternative. Graphitic
carbon nitrides, a class of metal-free polymers that can be easily prepared from
bulk chemicals, are heterogeneous semiconductors with high potential for photocatalytic
organic transformations. Here, we demonstrate that graphitic carbon nitrides in
combination with nickel catalysis can induce selective C−O cross-couplings of
carboxylic acids with aryl halides, yielding the respective aryl esters in excellent
yield and selectivity. The heterogeneous organic photocatalyst exhibits a broad
substrate scope, is able to harvest green light, and can be recycled multiple
times. In situ FTIR was used to track the reaction progress to study this transformation
at different irradiation wavelengths and reaction scales.

text: Differentially protected galactosamine building blocks are key components
for the synthesis of human and bacterial oligosaccharides. The azidophenylselenylation
of 3,4,6-tri-O-acetyl-d-galactal provides straightforward access to the corresponding
2-nitrogenated glycoside. Poor reproducibility and the use of azides that lead
to the formation of potentially explosive and toxic species limit the scalability
of this reaction and render it a bottleneck for carbohydrate synthesis. Here,
we present a method for the safe, efficient, and reliable azidophenylselenylation
of 3,4,6-tri-O-acetyl-d-galactal at room temperature, using continuous flow chemistry.
Careful analysis of the transformation resulted in reaction conditions that produce
minimal side products while the reaction time was reduced drastically when compared
to batch reactions. The flow setup is readily scalable to process 5 mmol of galactal
in 3 h, producing 1.2 mmol/h of product.

text: A carbon nitride material can be combined with homogeneous nickel catalysts
for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions.
The metal-free heterogeneous semiconductor is fully recyclable and couples a broad
range of electron-poor aryl bromides with primary and secondary alcohols as well
as water. The application for intramolecular reactions and the synthesis of active
pharmaceutical ingredients was demonstrated. The catalytic protocol is applicable
for the coupling of aryl iodides with thiols as well.

text: The transcription coactivator, Yes-associated protein (YAP), which is a nuclear
effector of the Hippo signaling pathway, has been shown to be a mechano-transducer.
By using mutant fish and human 3D spheroids, we have recently demonstrated that
YAP is also a mechano-effector. YAP functions in three-dimensional (3D) morphogenesis
of organ and global body shape by controlling actomyosin-mediated tissue tension.
In this chapter, we present a platform that links the findings in fish embryos
with human cells. The protocols for analyzing tissue tension-mediated global body
shape/organ morphogenesis in vivo and ex vivo using medaka fish embryos and in
vitro using human cell spheroids represent useful tools for unraveling the molecular
mechanisms by which YAP functions in regulating global body/organ morphogenesis.

text: 'Cryptographic security is usually defined as a guarantee that holds except
when a bad event with negligible probability occurs, and nothing is guaranteed
in that bad case. However, in settings where such failure can happen with substantial
probability, one needs to provide guarantees even for the bad case. A typical
example is where a (possibly weak) password is used instead of a secure cryptographic
key to protect a session, the bad event being that the adversary correctly guesses
the password. In a situation with multiple such sessions, a per-session guarantee
is desired: any session for which the password has not been guessed remains secure,
independently of whether other sessions have been compromised. A new formalism
for stating such gracefully degrading security guarantees is introduced and applied
to analyze the examples of password-based message authentication and password-based
encryption. While a natural per-message guarantee is achieved for authentication,
the situation of password-based encryption is more delicate: a per-session confidentiality
guarantee only holds against attackers for which the distribution of password-guessing
effort over the sessions is known in advance. In contrast, for more general attackers
without such a restriction, a strong, composable notion of security cannot be
achieved.'

text: We propose a new non-orthogonal basis to express the 3D Euclidean space in
terms of a regular grid. Every grid point, each represented by integer 3-coordinates,
corresponds to rhombic dodecahedron centroid. 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 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.
A characterization of a 3D digital sphere with relevant topological features is
proposed as well with the help of a 48 symmetry that comes with the new coordinate
system.

text: We give non-degeneracy criteria for Riemannian simplices based on simplices
in spaces of constant sectional curvature. It extends previous work on Riemannian
simplices, where we developed Riemannian simplices with respect to Euclidean reference
simplices. The criteria we give in this article are in terms of quality measures
for spaces of constant curvature that we develop here. We see that simplices in
spaces that have nearly constant curvature, are already non-degenerate under very
weak quality demands. This is of importance because it allows for sampling of
Riemannian manifolds based on anisotropy of the manifold and not (absolute) curvature.

text: We construct a verifiable delay function (VDF) by showing how the Rivest-Shamir-Wagner
time-lock puzzle can be made publicly verifiable. Concretely, we give a statistically
sound public-coin protocol to prove that a tuple (N,x,T,y) satisfies y=x2T (mod
N) where the prover doesn’t know the factorization of N and its running time is
dominated by solving the puzzle, that is, compute x2T, which is conjectured to
require T sequential squarings. To get a VDF we make this protocol non-interactive
using the Fiat-Shamir heuristic.The motivation for this work comes from the Chia
blockchain design, which uses a VDF as akey ingredient. For typical parameters
(T≤2 40, N= 2048), our proofs are of size around 10K B, verification cost around
three RSA exponentiations and computing the proof is 8000 times faster than solving
the puzzle even without any parallelism.

text: In this paper, we address the problem of synthesizing periodic switching controllers
for stabilizing a family of linear systems. Our broad approach consists of constructing
a finite game graph based on the family of linear systems such that every winning
strategy on the game graph corresponds to a stabilizing switching controller for
the family of linear systems. The construction of a (finite) game graph, the synthesis
of a winning strategy and the extraction of a stabilizing controller are all computationally
feasible. We illustrate our method on an example.

text: Fejes Tóth [5] and Schneider [9] studied approximations of smooth convex hypersurfaces
in Euclidean space by piecewise flat triangular meshes with a given number
of vertices on the hypersurface that are optimal with respect to Hausdorff distance. They proved that this
Hausdorff distance decreases inversely proportional with m 2/(d−1), where m is the number of vertices and
d is the dimension of Euclidean space. Moreover the pro-portionality constant
can be expressed in terms of the Gaussian curvature, an intrinsic quantity. In
this short note, we prove the extrinsic nature of this constant for manifolds
of sufficiently high codimension. We do so by constructing an family of isometric
embeddings of the flat torus in Euclidean space.

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\r\nneeded
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: Chemical labeling of proteins with synthetic molecular probes offers the possibility
to probe the functions of proteins of interest in living cells. However, the methods
for covalently labeling targeted proteins using complementary peptide tag-probe
pairs are still limited, irrespective of the versatility of such pairs in biological
research. Herein, we report the new CysHis tag-Ni(II) probe pair for the specific
covalent labeling of proteins. A broad-range evaluation of the reactivity profiles
of the probe and the CysHis peptide tag afforded a tag-probe pair with an optimized
and high labeling selectivity and reactivity. In particular, the labeling specificity
of this pair was notably improved compared to the previously reported one. This
pair was successfully utilized for the fluorescence imaging of membrane proteins
on the surfaces of living cells, demonstrating its potential utility in biological
research.

text: "In phase retrieval, we want to recover an unknown signal \U0001D465∈ℂ\U0001D451
from n quadratic measurements of the form \U0001D466\U0001D456=|⟨\U0001D44E\U0001D456,\U0001D465⟩|2+\U0001D464\U0001D456,
where \U0001D44E\U0001D456∈ℂ\U0001D451 are known sensing vectors and \U0001D464\U0001D456
is measurement noise. We ask the following weak recovery question: What is the
minimum number of measurements n needed to produce an estimator \U0001D465^(\U0001D466)
that is positively correlated with the signal \U0001D465? We consider the case
of Gaussian vectors \U0001D44E\U0001D44E\U0001D456. We prove that—in the high-dimensional
limit—a sharp phase transition takes place, and we locate the threshold in the
regime of vanishingly small noise. For \U0001D45B≤\U0001D451−\U0001D45C(\U0001D451),
no estimator can do significantly better than random and achieve a strictly positive
correlation. For \U0001D45B≥\U0001D451+\U0001D45C(\U0001D451), a simple spectral
estimator achieves a positive correlation. Surprisingly, numerical simulations
with the same spectral estimator demonstrate promising performance with realistic
sensing matrices. Spectral methods are used to initialize non-convex optimization
algorithms in phase retrieval, and our approach can boost the performance in this
setting as well. Our impossibility result is based on classical information-theoretic
arguments. The spectral algorithm computes the leading eigenvector of a weighted
empirical covariance matrix. We obtain a sharp characterization of the spectral
properties of this random matrix using tools from free probability and generalizing
a recent result by Lu and Li. Both the upper bound and lower bound generalize
beyond phase retrieval to measurements \U0001D466\U0001D456 produced according
to a generalized linear model. As a by-product of our analysis, we compare the
threshold of the proposed spectral method with that of a message passing algorithm."

text: The construction of anisotropic triangulations is desirable for various applications,
such as the numerical solving of partial differential equations and the representation
of surfaces in graphics. To solve this notoriously difficult problem in a practical
way, we introduce the discrete Riemannian Voronoi diagram, a discrete structure
that approximates the Riemannian Voronoi diagram. This structure has been implemented
and was shown to lead to good triangulations in $\mathbb{R}^2$ and on surfaces
embedded in $\mathbb{R}^3$ as detailed in our experimental companion paper. In
this paper, we study theoretical aspects of our structure. Given a finite set
of points $\mathcal{P}$ in a domain $\Omega$ equipped with a Riemannian metric,
we compare the discrete Riemannian Voronoi diagram of $\mathcal{P}$ to its Riemannian
Voronoi diagram. Both diagrams have dual structures called the discrete Riemannian
Delaunay and the Riemannian Delaunay complex. We provide conditions that guarantee
that these dual structures are identical. It then follows from previous results
that the discrete Riemannian Delaunay complex can be embedded in $\Omega$ under
sufficient conditions, leading to an anisotropic triangulation with curved simplices.
Furthermore, we show that, under similar conditions, the simplices of this triangulation
can be straightened.

text: "A Valued Constraint Satisfaction Problem (VCSP) provides a common framework
that can express a wide range of discrete optimization problems. A VCSP instance
is given by a finite set of variables, a finite domain of labels, and an objective
function to be minimized. This function is represented as a sum of terms where
each term depends on a subset of the variables. To obtain different classes of
optimization problems, one can restrict all terms to come from a fixed set Γ of
cost functions, called a language. \r\nRecent breakthrough results have established
a complete complexity classification of such classes with respect to language
Γ: if all cost functions in Γ satisfy a certain algebraic condition then all Γ-instances
can be solved in polynomial time, otherwise the problem is NP-hard. Unfortunately,
testing this condition for a given language Γ is known to be NP-hard. We thus
study exponential algorithms for this meta-problem. We show that the tractability
condition of a finite-valued language Γ can be tested in O(3‾√3|D|⋅poly(size(Γ)))
time, where D is the domain of Γ and poly(⋅) is some fixed polynomial. We also
obtain a matching lower bound under the Strong Exponential Time Hypothesis (SETH).
More precisely, we prove that for any constant δ<1 there is no O(3‾√3δ|D|) algorithm,
assuming that SETH holds."

text: Randomness is an essential part of any secure cryptosystem, but many constructions
rely on distributions that are not uniform. This is particularly true for lattice
based cryptosystems, which more often than not make use of discrete Gaussian distributions
over the integers. For practical purposes it is crucial to evaluate the impact
that approximation errors have on the security of a scheme to provide the best
possible trade-off between security and performance. Recent years have seen surprising
results allowing to use relatively low precision while maintaining high levels
of security. A key insight in these results is that sampling a distribution with
low relative error can provide very strong security guarantees. Since floating
point numbers provide guarantees on the relative approximation error, they seem
a suitable tool in this setting, but it is not obvious which sampling algorithms
can actually profit from them. While previous works have shown that inversion
sampling can be adapted to provide a low relative error (Pöppelmann et al., CHES
2014; Prest, ASIACRYPT 2017), other works have called into question if this is
possible for other sampling techniques (Zheng et al., Eprint report 2018/309).
In this work, we consider all sampling algorithms that are popular in the cryptographic
setting and analyze the relationship of floating point precision and the resulting
relative error. We show that all of the algorithms either natively achieve a low
relative error or can be adapted to do so.

text: Consider the problem of constructing a polar code of block length N for a
given transmission channel W. Previous approaches require one to compute the reliability
of the N synthetic channels and then use only those that are sufficiently reliable.
However, we know from two independent works by Schürch and by Bardet et al. that
the synthetic channels are partially ordered with respect to degradation. Hence,
it is natural to ask whether the partial order can be exploited to reduce the
computational burden of the construction problem. We show that, if we take advantage
of the partial order, we can construct a polar code by computing the reliability
of roughly a fraction 1/ log 3/2 N of the synthetic channels. In particular, we
prove that N/ log 3/2 N is a lower bound on the number of synthetic channels to
be considered and such a bound is tight up to a multiplicative factor log log
N. This set of roughly N/ log 3/2 N synthetic channels is universal, in the sense
that it allows one to construct polar codes for any W, and it can be identified
by solving a maximum matching problem on a bipartite graph. Our proof technique
consists of reducing the construction problem to the problem of computing the
maximum cardinality of an antichain for a suitable partially ordered set. As such,
this method is general, and it can be used to further improve the complexity of
the construction problem, in case a refined partial order on the synthetic channels
of polar codes is discovered.

text: "We establish connections between the problem of learning a two-layer neural
network and tensor decomposition. We consider a model with feature vectors x∈ℝd,
r hidden units with weights {wi}1≤i≤r and output y∈ℝ, i.e., y=∑ri=1σ(w\U0001D5B3ix),
with activation functions given by low-degree polynomials. In particular, if σ(x)=a0+a1x+a3x3,
we prove that no polynomial-time learning algorithm can outperform the trivial
predictor that assigns to each example the response variable \U0001D53C(y), when
d3/2≪r≪d2. Our conclusion holds for a `natural data distribution', namely standard
Gaussian feature vectors x, and output distributed according to a two-layer neural
network with random isotropic weights, and under a certain complexity-theoretic
assumption on tensor decomposition. Roughly speaking, we assume that no polynomial-time
algorithm can substantially outperform current methods for tensor decomposition
based on the sum-of-squares hierarchy. We also prove generalizations of this statement
for higher degree polynomial activations, and non-random weight vectors. Remarkably,
several existing algorithms for learning two-layer networks with rigorous guarantees
are based on tensor decomposition. Our results support the idea that this is indeed
the core computational difficulty in learning such networks, under the stated
generative model for the data. As a side result, we show that under this model
learning the network requires accurate learning of its weights, a property that
does not hold in a more general setting. "

text: 'Polar codes have gained extensive attention during the past few years and
recently they have been selected for the next generation of wireless communications
standards (5G). Successive-cancellation-based (SC-based) decoders, such as SC
list (SCL) and SC flip (SCF), provide a reasonable error performance for polar
codes at the cost of low decoding speed. Fast SC-based decoders, such as Fast-SSC,
Fast-SSCL, and Fast-SSCF, identify the special constituent codes in a polar code
graph off-line, produce a list of operations, store the list in memory, and feed
the list to the decoder to decode the constituent codes in order efficiently,
thus increasing the decoding speed. However, the list of operations is dependent
on the code rate and as the rate changes, a new list is produced, making fast
SC-based decoders not rate-flexible. In this paper, we propose a completely rate-flexible
fast SC-based decoder by creating the list of operations directly in hardware,
with low implementation complexity. We further propose a hardware architecture
implementing the proposed method and show that the area occupation of the rate-flexible
fast SC-based decoder in this paper is only 38% of the total area of the memory-based
base-line decoder when 5G code rates are supported. '

text: "We consider the graph class Grounded-L corresponding to graphs that admit
an intersection representation by L-shaped curves, where additionally the topmost
points of each curve are assumed to belong to a common horizontal line. We prove
that Grounded-L graphs admit an equivalent characterisation in terms of vertex
ordering with forbidden patterns. \r\nWe also compare this class to related intersection
classes, such as the grounded segment graphs, the monotone L-graphs (a.k.a. max
point-tolerance graphs), or the outer-1-string graphs. We give constructions showing
that these classes are all distinct and satisfy only trivial or previously known
inclusions."

text: "In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the qualitative winner or quantitative
payoff of the game. In bidding games, in each turn, we hold an auction between
the two players to determine which player moves the token. Bidding games have
largely been studied with concrete bidding mechanisms that are variants of a first-price
auction: in each turn both players simultaneously submit bids, the higher\r\nbidder
moves the token, and pays his bid to the lower bidder in Richman bidding, to the
bank in poorman bidding, and in taxman bidding, the bid is split between the other
player and the bank according to a predefined constant factor. Bidding games are
deterministic games. They have an intriguing connection with a fragment of stochastic
games called \r\n randomturn games. We study, for the first time, a combination
of bidding games with probabilistic behavior; namely, we study bidding games that
are played on Markov decision processes, where the players bid for the right to
choose the next action, which determines the probability distribution according
to which the next vertex is chosen. We study parity and meanpayoff bidding games
on MDPs and extend results from the deterministic bidding setting to the probabilistic
one."

text: 'The fundamental model-checking problem, given as input a model and a specification,
asks for the algorithmic verification of whether the model satisfies the specification.
Two classical models for reactive systems are graphs and Markov decision processes
(MDPs). A basic specification formalism in the verification of reactive systems
is the strong fairness (aka Streett) objective, where given different types of
requests and corresponding grants, the requirement is that for each type, if the
request event happens infinitely often, then the corresponding grant event must
also happen infinitely often. All omega-regular objectives can be expressed as
Streett objectives and hence they are canonical in verification. Consider graphs/MDPs
with n vertices, m edges, and a Streett objectives with k pairs, and let b denote
the size of the description of the Streett objective for the sets of requests
and grants. The current best-known algorithm for the problem requires time O(min(n^2,
m sqrt{m log n}) + b log n). In this work we present randomized near-linear time
algorithms, with expected running time O~(m + b), where the O~ notation hides
poly-log factors. Our randomized algorithms are near-linear in the size of the
input, and hence optimal up to poly-log factors. '

text: In this paper, we design novel liquid time-constant recurrent neural networks
for robotic control, inspired by the brain of the nematode, C. elegans. In the
worm's nervous system, neurons communicate through nonlinear time-varying synaptic
links established amongst them by their particular wiring structure. This property
enables neurons to express liquid time-constants dynamics and therefore allows
the network to originate complex behaviors with a small number of neurons. We
identify neuron-pair communication motifs as design operators and use them to
configure compact neuronal network structures to govern sequential robotic tasks.
The networks are systematically designed to map the environmental observations
to motor actions, by their hierarchical topology from sensory neurons, through
recurrently-wired interneurons, to motor neurons. The networks are then parametrized
in a supervised-learning scheme by a search-based algorithm. We demonstrate that
obtained networks realize interpretable dynamics. We evaluate their performance
in controlling mobile and arm robots, and compare their attributes to other artificial
neural network-based control agents. Finally, we experimentally show their superior
resilience to environmental noise, compared to the existing machine learning-based
methods.

text: 'In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the winner of the game. Such games
are central in formal methods since they model the interaction between a non-terminating
system and its environment. In bidding games the players bid for the right to
move the token: in each round, the players simultaneously submit bids, and the
higher bidder moves the token and pays the other player. Bidding games are known
to have a clean and elegant mathematical structure that relies on the ability
of the players to submit arbitrarily small bids. Many applications, however, require
a fixed granularity for the bids, which can represent, for example, the monetary
value expressed in cents. We study, for the first time, the combination of discrete-bidding
and infinite-duration games. Our most important result proves that these games
form a large determined subclass of concurrent games, where determinacy is the
strong property that there always exists exactly one player who can guarantee
winning the game. In particular, we show that, in contrast to non-discrete bidding
games, the mechanism with which tied bids are resolved plays an important role
in discrete-bidding games. We study several natural tie-breaking mechanisms and
show that, while some do not admit determinacy, most natural mechanisms imply
determinacy for every pair of initial budgets. '

text: 'A vector addition system with states (VASS) consists of a finite set of states
and counters. A configuration is a state and a value for each counter; a transition
changes the state and each counter is incremented, decremented, or left unchanged.
While qualitative properties such as state and configuration reachability have
been studied for VASS, we consider the long-run average cost of infinite computations
of VASS. The cost of a configuration is for each state, a linear combination of
the counter values. In the special case of uniform cost functions, the linear
combination is the same for all states. The (regular) long-run emptiness problem
is, given a VASS, a cost function, and a threshold value, if there is a (lasso-shaped)
computation such that the long-run average value of the cost function does not
exceed the threshold. For uniform cost functions, we show that the regular long-run
emptiness problem is (a) decidable in polynomial time for integer-valued VASS,
and (b) decidable but nonelementarily hard for natural-valued VASS (i.e., nonnegative
counters). For general cost functions, we show that the problem is (c) NP-complete
for integer-valued VASS, and (d) undecidable for natural-valued VASS. Our most
interesting result is for (c) integer-valued VASS with general cost functions,
where we establish a connection between the regular long-run emptiness problem
and quadratic Diophantine inequalities. The general (nonregular) long-run emptiness
problem is equally hard as the regular problem in all cases except (c), where
it remains open. '

text: 'We study Markov decision processes and turn-based stochastic games with parity
conditions. There are three qualitative winning criteria, namely, sure winning,
which requires all paths to satisfy the condition, almost-sure winning, which
requires the condition to be satisfied with probability 1, and limit-sure winning,
which requires the condition to be satisfied with probability arbitrarily close
to 1. We study the combination of two of these criteria for parity conditions,
e.g., there are two parity conditions one of which must be won surely, and the
other almost-surely. The problem has been studied recently by Berthon et al. for
MDPs with combination of sure and almost-sure winning, under infinite-memory strategies,
and the problem has been established to be in NP cap co-NP. Even in MDPs there
is a difference between finite-memory and infinite-memory strategies. Our main
results for combination of sure and almost-sure winning are as follows: (a) we
show that for MDPs with finite-memory strategies the problem is in NP cap co-NP;
(b) we show that for turn-based stochastic games the problem is co-NP-complete,
both for finite-memory and infinite-memory strategies; and (c) we present algorithmic
results for the finite-memory case, both for MDPs and turn-based stochastic games,
by reduction to non-stochastic parity games. In addition we show that all the
above complexity results also carry over to combination of sure and limit-sure
winning, and results for all other combinations can be derived from existing results
in the literature. Thus we present a complete picture for the study of combinations
of two qualitative winning criteria for parity conditions in MDPs and turn-based
stochastic games. '

faulty. In the\r\napproximate agreement task, each processor i receives an input
value xi and has to decide on an\r\noutput value yi such that\r\n1. the output
values are in the convex hull of the non-faulty processors’ input values,\r\n2.
the output values are within distance d of each other.\r\n\r\n\r\nClassically,
the values are assumed to be from an m-dimensional Euclidean space, where m ≥
1.\r\nIn this work, we study the task in a discrete setting, where input values
with some structure\r\nexpressible as a graph. Namely, the input values are vertices
of a finite graph G and the goal is to\r\noutput vertices that are within distance
d of each other in G, but still remain in the graph-induced\r\nconvex hull of
the input values. For d = 0, the task reduces to consensus and cannot be solved
with\r\na deterministic algorithm in an asynchronous system even with a single
crash fault. For any d ≥ 1,\r\nwe show that the task is solvable in asynchronous
systems when G is chordal and n > (ω + 1)f,\r\nwhere ω is the clique number of
G. In addition, we give the first Byzantine-tolerant algorithm for a\r\nvariant
of lattice agreement. For synchronous systems, we show tight resilience bounds
for the exact\r\nvariants of these and related tasks over a large class of combinatorial
structures."

text: In this paper, we introduce a novel method to interpret recurrent neural networks
(RNNs), particularly long short-term memory networks (LSTMs) at the cellular level.
We propose a systematic pipeline for interpreting individual hidden state dynamics
within the network using response characterization methods. The ranked contribution
of individual cells to the network's output is computed by analyzing a set of
interpretable metrics of their decoupled step and sinusoidal responses. As a result,
our method is able to uniquely identify neurons with insightful dynamics, quantify
relationships between dynamical properties and test accuracy through ablation
analysis, and interpret the impact of network capacity on a network's dynamical
distribution. Finally, we demonstrate the generalizability and scalability of
our method by evaluating a series of different benchmark sequential datasets.

text: 'We consider the primitive relay channel, where the source sends a message
to the relay and to the destination, and the relay helps the communication by
transmitting an additional message to the destination via a separate channel.
Two well-known coding techniques have been introduced for this setting: decode-and-forward
and compress-and-forward. In decode-and-forward, the relay completely decodes
the message and sends some information to the destination; in compress-and-forward,
the relay does not decode, and it sends a compressed version of the received signal
to the destination using Wyner–Ziv coding. In this paper, we present a novel coding
paradigm that provides an improved achievable rate for the primitive relay channel.
The idea is to combine compress-and-forward and decode-and-forward via a chaining
construction. We transmit over pairs of blocks: in the first block, we use compress-and-forward;
and, in the second block, we use decode-and-forward. More specifically, in the
first block, the relay does not decode, it compresses the received signal via
Wyner–Ziv, and it sends only part of the compression to the destination. In the
second block, the relay completely decodes the message, it sends some information
to the destination, and it also sends the remaining part of the compression coming
from the first block. By doing so, we are able to strictly outperform both compress-and-forward
and decode-and-forward. Note that the proposed coding scheme can be implemented
with polar codes. As such, it has the typical attractive properties of polar coding
schemes, namely, quasi-linear encoding and decoding complexity, and error probability
that decays at super-polynomial speed. As a running example, we take into account
the special case of the erasure relay channel, and we provide a comparison between
the rates achievable by our proposed scheme and the existing upper and lower bounds.'

text: 'The aim of this short note is to expound one particular issue that was discussed
during the talk [10] given at the symposium ”Researches on isometries as preserver
problems and related topics” at Kyoto RIMS. That is, the role of Dirac masses
by describing the isometry group of various metric spaces of probability measures. This article is of survey character, and it does not contain any essentially new
results.From an isometric point of view, in some cases, metric spaces of measures
are similar to C(K)-type function spaces. Similarity means here that their isometries are driven by some nice transformations
of the underlying space. Of course, it depends on the particular choice of the metric how nice these
transformations should be. Sometimes, as we will see, being a homeomorphism is
enough to generate an isometry. But sometimes we need more: the transformation
must preserve the underlying distance as well. Statements claiming that isometries
in questions are necessarily induced by homeomorphisms are called Banach-Stone-type
results, while results asserting that the underlying transformation is necessarily
an isometry are termed as isometric rigidity results.As Dirac masses can be considered as building bricks of the set of all Borel measures, a natural
question arises:Is it enough to understand how an isometry acts on the set of
Dirac masses? Does this action extend uniquely to all measures?In what follows,
we will thoroughly investigate this question.'

text: A recent class of topological nodal-line semimetals with the general formula
MSiX (M = Zr, Hf and X = S, Se, Te) has attracted much experimental and theoretical
interest due to their properties, particularly their large magnetoresistances
and high carrier mobilities. The plateletlike nature of the MSiX crystals and
their extremely low residual resistivities make measurements of the resistivity
along the [001] direction extremely challenging. To accomplish such measurements,
microstructures of single crystals were prepared using focused ion beam techniques.
Microstructures prepared in this manner have very well-defined geometries and
maintain their high crystal quality, verified by the observations of quantum oscillations.
We present magnetoresistance and quantum oscillation data for currents applied
along both [001] and [100] in ZrSiS and ZrSiSe, which are consistent with the
nontrivial topology of the Dirac line-node, as determined by a measured π Berry
phase. Surprisingly, we find that, despite the three dimensional nature of both
the Fermi surfaces of ZrSiS and ZrSiSe, both the resistivity anisotropy under
applied magnetic fields and the in-plane angular dependent magnetoresistance differ
considerably between the two compounds. Finally, we discuss the role microstructuring
can play in the study of these materials and our ability to make these microstructures
free-standing.

text: We present a high magnetic field study of NbP—a member of the monopnictide
Weyl semimetal (WSM) family. While the monoarsenides (NbAs and TaAs) have topologically
distinct left and right-handed Weyl fermi surfaces, NbP is argued to be “topologically
trivial” due to the fact that all pairs of Weyl nodes are encompassed by a single
Fermi surface. We use torque magnetometry to measure the magnetic response of
NbP up to 60 tesla and uncover a Berry paramagnetic response, characteristic of
the topological Weyl nodes, across the entire field range. At the quantum limit
B* (≈32 T), τ/B experiences a change in slope when the chemical potential enters
the last Landau level. Our calculations confirm that this magnetic response arises
from band topology of the Weyl pocket, even though the Fermi surface encompasses
both Weyl nodes at zero magnetic field. We also find that the magnetic field pulls
the chemical potential to the chiral n = 0 Landau level in the quantum limit,
providing a disorder-free way of accessing chiral Weyl fermions in systems that
are “not quite” WSMs in zero magnetic field.

text: "In the Ca1−x La x FeAs2 (1 1 2) family of pnictide superconductors, we have
investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure,
high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition
at T N = 120 K, well above the one at lower doping (0.15 < x < 0.27).\r\n\r\nBelow
the onset of long-range magnetic order at T N, the electrical resistivity is strongly
reduced and is dominated by electron–electron interactions, as evident from its
temperature dependence. The Seebeck coefficient shows a clear metallic behavior
as in narrow band conductors. The temperature dependence of the Hall coefficient
and the violation of Kohler's rule agree with the multiband character of the material.
No superconductivity was observed down to 1.8 K. The success of the high-pressure
synthesis encourages further investigations of the so far only partially explored
phase diagram in this family of Iron-based high temperature superconductors.\r\n"

text: Although crystals of strongly correlated metals exhibit a diverse set of electronic
ground states, few approaches exist for spatially modulating their properties.
In this study, we demonstrate disorder-free control, on the micrometer scale,
over the superconducting state in samples of the heavy-fermion superconductor
CeIrIn5. We pattern crystals by focused ion beam milling to tailor the boundary
conditions for the elastic deformation upon thermal contraction during cooling.
The resulting nonuniform strain fields induce complex patterns of superconductivity,
owing to the strong dependence of the transition temperature on the strength and
direction of strain. These results showcase a generic approach to manipulating
electronic order on micrometer length scales in strongly correlated matter without
compromising the cleanliness, stoichiometry, or mean free path.

text: Loss of functional cardiomyocytes is a major determinant of heart failure
after myocardial infarction. Previous high throughput screening studies have identified
a few microRNAs (miRNAs) that can induce cardiomyocyte proliferation and stimulate
cardiac regeneration in mice. Here, we show that all of the most effective of
these miRNAs activate nuclear localization of the master transcriptional cofactor
Yes-associated protein (YAP) and induce expression of YAP-responsive genes. In
particular, miR-199a-3p directly targets two mRNAs coding for proteins impinging
on the Hippo pathway, the upstream YAP inhibitory kinase TAOK1, and the E3 ubiquitin
ligase β-TrCP, which leads to YAP degradation. Several of the pro-proliferative
miRNAs (including miR-199a-3p) also inhibit filamentous actin depolymerization
by targeting Cofilin2, a process that by itself activates YAP nuclear translocation.
Thus, activation of YAP and modulation of the actin cytoskeleton are major components
of the pro-proliferative action of miR-199a-3p and other miRNAs that induce cardiomyocyte
proliferation.

text: "We show that statistical criticality, i.e. the occurrence of power law frequency
distributions, arises in samples that are maximally informative about the underlying
generating process. In order to reach this conclusion, we first identify the frequency
with which different outcomes occur in a sample, as the variable carrying useful
information on the generative process. The entropy of the frequency, that we call
relevance, provides an upper bound to the number of informative bits. This differs
from the entropy of the data, that we take as a measure of resolution. Samples
that maximise relevance at a given resolution—that we call maximally informative
samples—exhibit statistical criticality. In particular, Zipf's law arises at the
optimal trade-off between resolution (i.e. compression) and relevance. As a byproduct,
we derive a bound of the maximal number of parameters that can be estimated from
a dataset, in the absence of prior knowledge on the generative model.\r\n\r\nFurthermore,
we relate criticality to the statistical properties of the representation of the
data generating process. We show that, as a consequence of the concentration property
of the asymptotic equipartition property, representations that are maximally informative
about the data generating process are characterised by an exponential distribution
of energy levels. This arises from a principle of minimal entropy, that is conjugate
of the maximum entropy principle in statistical mechanics. This explains why statistical
criticality requires no parameter fine tuning in maximally informative samples."

text: "In this work, we use algebraic methods for studying distance computation
and subgraph detection tasks in the congested clique model. Specifically, we adapt
parallel matrix multiplication implementations to the congested clique, obtaining
an O(n1−2/ω) round matrix multiplication algorithm, where ω<2.3728639 is the exponent
of matrix multiplication. In conjunction with known techniques from centralised
algorithmics, this gives significant improvements over previous best upper bounds
in the congested clique model. The highlight results include:\r\n\r\n1. triangle
and 4-cycle counting in O(n0.158) rounds, improving upon the O(n1/3) algorithm
of Dolev et al. [DISC 2012],\r\n2. a (1+o(1))-approximation of all-pairs shortest
paths in O(n0.158) rounds, improving upon the O~(n1/2)-round (2+o(1))-approximation
algorithm given by Nanongkai [STOC 2014], and\r\n 3. computing the girth in O(n0.158)
rounds, which is the first non-trivial solution in this model.\r\n \r\nIn addition,
we present a novel constant-round combinatorial algorithm for detecting 4-cycles."

text: Aprotic alkali metal–oxygen batteries require reversible formation of metal
superoxide or peroxide on cycling. Severe parasitic reactions cause poor rechargeability,
efficiency, and cycle life and have been shown to be caused by singlet oxygen
(1O2) that forms at all stages of cycling. However, its formation mechanism remains
unclear. We show that disproportionation of superoxide, the product or intermediate
on discharge and charge, to peroxide and oxygen is responsible for 1O2 formation.
While the overall reaction is driven by the stability of peroxide and thus favored
by stronger Lewis acidic cations such as Li+, the 1O2 fraction is enhanced by
weak Lewis acids such as organic cations. Concurrently, the metal peroxide yield
drops with increasing 1O2. The results explain a major parasitic pathway during
cell cycling and the growing severity in K–, Na–, and Li–O2 cells based on the
growing propensity for disproportionation. High capacities and rates with peroxides
are now realized to require solution processes, which form peroxide or release
O2via disproportionation. The results therefore establish the central dilemma
that disproportionation is required for high capacity but also responsible for
irreversible reactions. Highly reversible cell operation requires hence finding
reaction routes that avoid disproportionation.

text: Non-aqueous lithium-oxygen batteries cycle by forming lithium peroxide during
discharge and oxidizing it during recharge. The significant problem of oxidizing
the solid insulating lithium peroxide can greatly be facilitated by incorporating
redox mediators that shuttle electron-holes between the porous substrate and lithium
peroxide. Redox mediator stability is thus key for energy efficiency, reversibility,
and cycle life. However, the gradual deactivation of redox mediators during repeated
cycling has not conclusively been explained. Here, we show that organic redox
mediators are predominantly decomposed by singlet oxygen that forms during cycling.
Their reaction with superoxide, previously assumed to mainly trigger their degradation,
peroxide, and dioxygen, is orders of magnitude slower in comparison. The reduced
form of the mediator is markedly more reactive towards singlet oxygen than the
oxidized form, from which we derive reaction mechanisms supported by density functional
theory calculations. Redox mediators must thus be designed for stability against
singlet oxygen.

text: Singlet oxygen (1O2) causes a major fraction of the parasitic chemistry during
the cycling of non‐aqueous alkali metal‐O2 batteries and also contributes to interfacial
reactivity of transition‐metal oxide intercalation compounds. We introduce DABCOnium,
the mono alkylated form of 1,4‐diazabicyclo[2.2.2]octane (DABCO), as an efficient
1O2 quencher with an unusually high oxidative stability of ca. 4.2 V vs. Li/Li+.
Previous quenchers are strongly Lewis basic amines with too low oxidative stability.
DABCOnium is an ionic liquid, non‐volatile, highly soluble in the electrolyte,
stable against superoxide and peroxide, and compatible with lithium metal. The
electrochemical stability covers the required range for metal–O2 batteries and
greatly reduces 1O2 related parasitic chemistry as demonstrated for the Li–O2
cell.

text: Li–O2 batteries are plagued by side reactions that cause poor rechargeability
and efficiency. These reactions were recently revealed to be predominantly caused
by singlet oxygen, which can be neutralized by chemical traps or physical quenchers.
However, traps are irreversibly consumed and thus only active for a limited time,
and so far identified quenchers lack oxidative stability to be suitable for typically
required recharge potentials. Thus, reducing the charge potential within the stability
limit of the quencher and/or finding more stable quenchers is required. Here,
we show that dimethylphenazine as a redox mediator decreases the charge potential
well within the stability limit of the quencher 1,4-diazabicyclo[2.2.2]octane.
The quencher can thus mitigate the parasitic reactions without being oxidatively
decomposed. At the same time the quencher protects the redox mediator from singlet
oxygen attack. The mutual conservation of the redox mediator and the quencher
is rational for stable and effective Li–O2 batteries.

text: In this issue of Joule, Dongmin Im and coworkers from Samsung in South Korea
describe a prototype lithium-O2 battery that reaches ∼700 Wh kg–1 and ∼600 Wh
L–1 on the cell level. They cut all components to the minimum to reach this value.
Difficulties filling the pores with discharge product and inhomogeneous cell utilization
turn out to limit the achievable energy. Their work underlines the importance
of reporting performance with respect to full cell weight and volume.

text: Telencephalic organoids generated from human pluripotent stem cells (hPSCs)
are emerging as an effective system to study the distinct features of the developing
human brain and the underlying causes of many neurological disorders. While progress
in organoid technology has been steadily advancing, many challenges remain including
rampant batch-to-batch and cell line-to-cell line variability and irreproducibility.
Here, we demonstrate that a major contributor to successful cortical organoid
production is the manner in which hPSCs are maintained prior to differentiation.
Optimal results were achieved using fibroblast-feeder-supported hPSCs compared
to feeder-independent cells, related to differences in their transcriptomic states.
Feeder-supported hPSCs display elevated activation of diverse TGFβ superfamily
signaling pathways and increased expression of genes associated with naïve pluripotency.
We further identify combinations of TGFβ-related growth factors that are necessary
and together sufficient to impart broad telencephalic organoid competency to feeder-free
hPSCs and enable reproducible formation of brain structures suitable for disease
modeling.

on the orientable surface M_g of genus g. A drawing of a graph on a surface is
independently even if every pair of nonadjacent edges in the drawing crosses an
even number of times. The Z_2-genus of a graph G, denoted by g_0(G), is the minimum
g such that G has an independently even drawing on M_g. By a result of Battle,
Harary, Kodama and Youngs from 1962, the graph genus is additive over 2-connected
blocks. In 2013, Schaefer and Stefankovic proved that the Z_2-genus of a graph
is additive over 2-connected blocks as well, and asked whether this result can
be extended to so-called 2-amalgamations, as an analogue of results by Decker,
Glover, Huneke, and Stahl for the genus. We give the following partial answer.
If G=G_1 cup G_2, G_1 and G_2 intersect in two vertices u and v, and G-u-v has
k connected components (among which we count the edge uv if present), then |g_0(G)-(g_0(G_1)+g_0(G_2))|<=k+1.
For complete bipartite graphs K_{m,n}, with n >= m >= 3, we prove that g_0(K_{m,n})/g(K_{m,n})=1-O(1/n).
Similar results are proved also for the Euler Z_2-genus. We express the Z_2-genus
of a graph using the minimum rank of partial symmetric matrices over Z_2; a problem
that might be of independent interest. '
