text: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. By analogy with the bipolaron, we introduce the biangulon quasiparticle
describing two rotating molecules that align with respect to each other due to
the effective attractive interaction mediated by the excitations of the bath.
We study this system in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, we introduce a diagonalization scheme that allows us to describe
the transition from two separated angulons to a biangulon as a function of the
distance between the two molecules.

text: "One of the most striking hallmarks of the eukaryotic cell is the presence
of intracellular vesicles and organelles. Each of these membrane-enclosed compartments
has a distinct composition of lipids and proteins, which is essential for accurate
membrane traffic and homeostasis. Interestingly, their biochemical identities
are achieved with the help\r\nof small GTPases of the Rab family, which cycle
between GDP- and GTP-bound forms on the selected membrane surface. While this
activity switch is well understood for an individual protein, how Rab GTPases
collectively transition between states to generate decisive signal propagation
in space and time is unclear. In my PhD thesis, I present\r\nin vitro reconstitution
experiments with theoretical modeling to systematically study a minimal Rab5 activation
network from bottom-up. We find that positive feedback based on known molecular
interactions gives rise to bistable GTPase activity switching on system’s scale.
Furthermore, we determine that collective transition near the critical\r\npoint
is intrinsically stochastic and provide evidence that the inactive Rab5 abundance
on the membrane can shape the network response. Finally, we demonstrate that collective
switching can spread on the lipid bilayer as a traveling activation wave, representing
a possible emergent activity pattern in endosomal maturation. Together, our\r\nfindings
reveal new insights into the self-organization properties of signaling networks
away from chemical equilibrium. Our work highlights the importance of systematic
characterization of biochemical systems in well-defined physiological conditions.
This way, we were able to answer long-standing open questions in the field and
close the gap between regulatory processes on a molecular scale and emergent responses
on system’s level."

text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
family, which are activated at defined times and locations in a switch-like manner.
While this switch is well understood for an individual protein, how regulatory
networks produce intracellular activity patterns is currently not known. Here,
we combine in vitro reconstitution experiments with computational modeling to
study a minimal Rab5 activation network. We find that the molecular interactions
in this system give rise to a positive feedback and bistable collective switching
of Rab5. Furthermore, we find that switching near the critical point is intrinsically
stochastic and provide evidence that controlling the inactive population of Rab5
on the membrane can shape the network response. Notably, we demonstrate that collective
switching can spread on the membrane surface as a traveling wave of Rab5 activation.
Together, our findings reveal how biochemical signaling networks control vesicle
trafficking pathways and how their nonequilibrium properties define the spatiotemporal
organization of the cell.

text: "Algorithms in computational 3-manifold topology typically take a triangulation
as an input and return topological information about the underlying 3-manifold.
However, extracting the desired information from a triangulation (e.g., evaluating
an invariant) is often computationally very expensive. In recent years this complexity
barrier has been successfully tackled in some cases by importing ideas from the
theory of parameterized algorithms into the realm of 3-manifolds. Various computationally
hard problems were shown to be efficiently solvable for input triangulations that
are sufficiently “tree-like.”\r\nIn this thesis we focus on the key combinatorial
parameter in the above context: we consider the treewidth of a compact, orientable
3-manifold, i.e., the smallest treewidth of the dual graph of any triangulation
thereof. By building on the work of Scharlemann–Thompson and Scharlemann–Schultens–Saito
on generalized Heegaard splittings, and on the work of Jaco–Rubinstein on layered
triangulations, we establish quantitative relations between the treewidth and
classical topological invariants of a 3-manifold. In particular, among other results,
we show that the treewidth of a closed, orientable, irreducible, non-Haken 3-manifold
is always within a constant factor of its Heegaard genus."

text: Asynchronous programs are notoriously difficult to reason about because they
spawn computation tasks which take effect asynchronously in a nondeterministic
way. Devising inductive invariants for such programs requires understanding and
stating complex relationships between an unbounded number of computation tasks
in arbitrarily long executions. In this paper, we introduce inductive sequentialization,
a new proof rule that sidesteps this complexity via a sequential reduction, a
sequential program that captures every behavior of the original program up to
reordering of coarse-grained commutative actions. A sequential reduction of a
concurrent program is easy to reason about since it corresponds to a simple execution
of the program in an idealized synchronous environment, where processes act in
a fixed order and at the same speed. We have implemented and integrated our proof
rule in the CIVL verifier, allowing us to provably derive fine-grained implementations
of asynchronous programs. We have successfully applied our proof rule to a diverse
set of message-passing protocols, including leader election protocols, two-phase
commit, and Paxos.

text: "During bacterial cell division, the tubulin-homolog FtsZ forms a ring-like
structure at the center of the cell. This so-called Z-ring acts as a scaffold
recruiting several division-related proteins to mid-cell and plays a key role
in distributing proteins at the division site, a feature driven by the treadmilling
motion of FtsZ filaments around the septum. What regulates the architecture, dynamics
and stability of the Z-ring is still poorly understood, but FtsZ-associated proteins
(Zaps) are known to play an important role. \r\nAdvances in fluorescence microscopy
and in vitro reconstitution experiments have helped to shed light into some of
the dynamic properties of these complex systems, but methods that allow to collect
and analyze large quantitative data sets of the underlying polymer dynamics are
still missing.\r\nHere, using an in vitro reconstitution approach, we studied
how different Zaps affect FtsZ filament dynamics and organization into large-scale
patterns, giving special emphasis to the role of the well-conserved protein ZapA.
For this purpose, we use high-resolution fluorescence microscopy combined with
novel image analysis workfows to study pattern organization and polymerization
dynamics of active filaments. We quantified the influence of Zaps on FtsZ on three
diferent spatial scales: the large-scale organization of the membrane-bound filament
network, the underlying\r\npolymerization dynamics and the behavior of single
molecules.\r\nWe found that ZapA cooperatively increases the spatial order of
the filament network, binds only transiently to FtsZ filaments and has no effect
on filament length and treadmilling velocity. Our data provides a model for how
FtsZ-associated proteins can increase the precision and stability of the bacterial
cell division machinery in a\r\nswitch-like manner, without compromising filament
dynamics. Furthermore, we believe that our automated quantitative methods can
be used to analyze a large variety of dynamic cytoskeletal systems, using standard
time-lapse\r\nmovies of homogeneously labeled proteins obtained from experiments
in vitro or even inside the living cell.\r\n"

text: 'Even though Delaunay originally introduced his famous triangulations in the
case of infinite point sets with translational periodicity, a software that computes
such triangulations in the general case is not yet available, to the best of our
knowledge. Combining and generalizing previous work, we present a practical algorithm
for computing such triangulations. The algorithm has been implemented and experiments
show that its performance is as good as the one of the CGAL package, which is
restricted to cubic periodicity. '

text: 'We address the following question: How redundant is the parameterisation
of ReLU networks? Specifically, we consider transformations of the weight space
which leave the function implemented by the network intact. Two such transformations
are known for feed-forward architectures: permutation of neurons within a layer,
and positive scaling of all incoming weights of a neuron coupled with inverse
scaling of its outgoing weights. In this work, we show for architectures with
non-increasing widths that permutation and scaling are in fact the only function-preserving
weight transformations. For any eligible architecture we give an explicit construction
of a neural network such that any other network that implements the same function
can be obtained from the original one by the application of permutations and rescaling. The
proof relies on a geometric understanding of boundaries between linear regions
of ReLU networks, and we hope the developed mathematical tools are of independent
interest.'

text: We consider the Pekar functional on a ball in ℝ3. We prove uniqueness of minimizers,
and a quadratic lower bound in terms of the distance to the minimizer. The latter
follows from nondegeneracy of the Hessian at the minimum.

text: 'In the present work, we consider the evolution of two fluids separated by
a sharp interface in the presence of surface tension—like, for example, the evolution
of oil bubbles in water. Our main result is a weak–strong uniqueness principle
for the corresponding free boundary problem for the incompressible Navier–Stokes
equation: as long as a strong solution exists, any varifold solution must coincide
with it. In particular, in the absence of physical singularities, the concept
of varifold solutions—whose global in time existence has been shown by Abels (Interfaces
Free Bound 9(1):31–65, 2007) for general initial data—does not introduce a mechanism
for non-uniqueness. The key ingredient of our approach is the construction of
a relative entropy functional capable of controlling the interface error. If the
viscosities of the two fluids do not coincide, even for classical (strong) solutions
the gradient of the velocity field becomes discontinuous at the interface, introducing
the need for a careful additional adaption of the relative entropy.'

text: We prove that in the absence of topological changes, the notion of BV solutions
to planar multiphase mean curvature flow does not allow for a mechanism for (unphysical)
non-uniqueness. Our approach is based on the local structure of the energy landscape
near a classical evolution by mean curvature. Mean curvature flow being the gradient
flow of the surface energy functional, we develop a gradient-flow analogue of
the notion of calibrations. Just like the existence of a calibration guarantees
that one has reached a global minimum in the energy landscape, the existence of
a "gradient flow calibration" ensures that the route of steepest descent in the
energy landscape is unique and stable.

text: 'The superconducting circuit community has recently discovered the promising
potential of superinductors. These circuit elements have a characteristic impedance
exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of
ground state charge fluctuations. Applications include the realization of hardware
protected qubits for fault tolerant quantum computing, improved coupling to small
dipole moment objects and defining a new quantum metrology standard for the ampere.
In this work we refute the widespread notion that superinductors can only be implemented
based on kinetic inductance, i.e. using disordered superconductors or Josephson
junction arrays. We present modeling, fabrication and characterization of 104
planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ
at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling
reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled
tunneling events and offer high reproducibility, linearity and the ability to
couple magnetically - properties that significantly broaden the scope of future
quantum circuits. '

text: This paper deals with dynamical optimal transport metrics defined by spatial
discretisation of the Benamou–Benamou formula for the Kantorovich metric . Such
metrics appear naturally in discretisations of -gradient flow formulations for
dissipative PDE. However, it has recently been shown that these metrics do not
in general converge to , unless strong geometric constraints are imposed on the
discrete mesh. In this paper we prove that, in a 1-dimensional periodic setting,
discrete transport metrics converge to a limiting transport metric with a non-trivial
effective mobility. This mobility depends sensitively on the geometry of the mesh
and on the non-local mobility at the discrete level. Our result quantifies to
what extent discrete transport can make use of microstructure in the mesh to reduce
the cost of transport.

text: We consider finite-volume approximations of Fokker-Planck equations on bounded
convex domains in R^d and study the corresponding gradient flow structures. We
reprove the convergence of the discrete to continuous Fokker-Planck equation via
the method of Evolutionary Γ-convergence, i.e., we pass to the limit at the level
of the gradient flow structures, generalising the one-dimensional result obtained
by Disser and Liero. The proof is of variational nature and relies on a Mosco
convergence result for functionals in the discrete-to-continuum limit that is
of independent interest. Our results apply to arbitrary regular meshes, even though
the associated discrete transport distances may fail to converge to the Wasserstein
distance in this generality.

text: "We study the problem of learning from multiple untrusted data sources, a
scenario of increasing practical relevance given the recent emergence of crowdsourcing
and collaborative learning paradigms. Specifically, we analyze the situation in
which a learning system obtains datasets from multiple sources, some of which
might be biased or even adversarially perturbed. It is\r\nknown that in the single-source
case, an adversary with the power to corrupt a fixed fraction of the training
data can prevent PAC-learnability, that is, even in the limit of infinitely much
training data, no learning system can approach the optimal test error. In this
work we show that, surprisingly, the same is not true in the multi-source setting,
where the adversary can arbitrarily\r\ncorrupt a fixed fraction of the data sources.
Our main results are a generalization bound that provides finite-sample guarantees
for this learning setting, as well as corresponding lower bounds. Besides establishing
PAC-learnability our results also show that in a cooperative learning setting
sharing data with other parties has provable benefits, even if some\r\nparticipants
are malicious. "

text: Determining the phase diagram of systems consisting of smaller subsystems
'connected' via a tunable coupling is a challenging task relevant for a variety
of physical settings. A general question is whether new phases, not present in
the uncoupled limit, may arise. We use machine learning and a suitable quasidistance
between different points of the phase diagram to study layered spin models, in
which the spin variables constituting each of the uncoupled systems (to which
we refer as layers) are coupled to each other via an interlayer coupling. In such
systems, in general, composite order parameters involving spins of different layers
may emerge as a consequence of the interlayer coupling. We focus on the layered
Ising and Ashkin–Teller models as a paradigmatic case study, determining their
phase diagram via the application of a machine learning algorithm to the Monte
Carlo data. Remarkably our technique is able to correctly characterize all the
system phases also in the case of hidden order parameters, i.e. order parameters
whose expression in terms of the microscopic configurations would require additional
preprocessing of the data fed to the algorithm. We correctly retrieve the three
known phases of the Ashkin–Teller model with ferromagnetic couplings, including
the phase described by a composite order parameter. For the bilayer and trilayer
Ising models the phases we find are only the ferromagnetic and the paramagnetic
ones. Within the approach we introduce, owing to the construction of convolutional
neural networks, naturally suitable for layered image-like data with arbitrary
number of layers, no preprocessing of the Monte Carlo data is needed, also with
regard to its spatial structure. The physical meaning of our results is discussed
and compared with analytical data, where available. Yet, the method can be used
without any a priori knowledge of the phases one seeks to find and can be applied
to other models and structures.

text: We consider the quantum mechanical many-body problem of a single impurity
particle immersed in a weakly interacting Bose gas. The impurity interacts with
the bosons via a two-body potential. We study the Hamiltonian of this system in
the mean-field limit and rigorously show that, at low energies, the problem is
well described by the Fröhlich polaron model.

text: 'Genes differ in the frequency at which they are expressed and in the form
of regulation used to control their activity. In particular, positive or negative
regulation can lead to activation of a gene in response to an external signal.
Previous works proposed that the form of regulation of a gene correlates with
its frequency of usage: positive regulation when the gene is frequently expressed
and negative regulation when infrequently expressed. Such network design means
that, in the absence of their regulators, the genes are found in their least required
activity state, hence regulatory intervention is often necessary. Due to the multitude
of genes and regulators, spurious binding and unbinding events, called “crosstalk”,
could occur. To determine how the form of regulation affects the global crosstalk
in the network, we used a mathematical model that includes multiple regulators
and multiple target genes. We found that crosstalk depends non-monotonically on
the availability of regulators. Our analysis showed that excess use of regulation
entailed by the formerly suggested network design caused high crosstalk levels
in a large part of the parameter space. We therefore considered the opposite ‘idle’
design, where the default unregulated state of genes is their frequently required
activity state. We found, that ‘idle’ design minimized the use of regulation and
thus minimized crosstalk. In addition, we estimated global crosstalk of S. cerevisiae
using transcription factors binding data. We demonstrated that even partial network
data could suffice to estimate its global crosstalk, suggesting its applicability
to additional organisms. We found that S. cerevisiae estimated crosstalk is lower
than that of a random network, suggesting that natural selection reduces crosstalk.
In summary, our study highlights a new type of protein production cost which is
typically overlooked: that of regulatory interference caused by the presence of
excess regulators in the cell. It demonstrates the importance of whole-network
descriptions, which could show effects missed by single-gene models.'

text: 'In mammals, chromatin marks at imprinted genes are asymmetrically inherited
to control parentally-biased gene expression. This control is thought predominantly
to involve parent-specific differentially methylated regions (DMR) in genomic
DNA. However, neither parent-of-origin-specific transcription nor DMRs have been
comprehensively mapped. We here address this by integrating transcriptomic and
epigenomic approaches in mouse preimplantation embryos (blastocysts). Transcriptome-analysis
identified 71 genes expressed with previously unknown parent-of-origin-specific
expression in blastocysts (nBiX: novel blastocyst-imprinted expression). Uniparental
expression of nBiX genes disappeared soon after implantation. Micro-whole-genome
bisulfite sequencing (μWGBS) of individual uniparental blastocysts detected 859
DMRs. Only 18% of nBiXs were associated with a DMR, whereas 60% were associated
with parentally-biased H3K27me3. This suggests a major role for Polycomb-mediated
imprinting in blastocysts. Five nBiX-clusters contained at least one known imprinted
gene, and five novel clusters contained exclusively nBiX-genes. These data suggest
a complex program of stage-specific imprinting involving different tiers of regulation.'

text: "Designing and verifying concurrent programs is a notoriously challenging,
time consuming, and error prone task, even for experts. This is due to the sheer
number of possible interleavings of a concurrent program, all of which have to
be tracked and accounted for in a formal proof. Inventing an inductive invariant
that captures all interleavings of a low-level implementation is theoretically
possible, but practically intractable. We develop a refinement-based verification
framework that provides mechanisms to simplify proof construction by decomposing
the verification task into smaller subtasks.\r\n\r\nIn a first line of work, we
present a foundation for refinement reasoning over structured concurrent programs.
We introduce layered concurrent programs as a compact notation to represent multi-layer
refinement proofs. A layered concurrent program specifies a sequence of connected
concurrent programs, from most concrete to most abstract, such that common parts
of different programs are written exactly once. Each program in this sequence
is expressed as structured concurrent program, i.e., a program over (potentially
recursive) procedures, imperative control flow, gated atomic actions, structured
parallelism, and asynchronous concurrency. This is in contrast to existing refinement-based
verifiers, which represent concurrent systems as flat transition relations. We
present a powerful refinement proof rule that decomposes refinement checking over
structured programs into modular verification conditions. Refinement checking
is supported by a new form of modular, parameterized invariants, called yield
invariants, and a linear permission system to enhance local reasoning.\r\n\r\nIn
a second line of work, we present two new reduction-based program transformations
that target asynchronous programs. These transformations reduce the number of
interleavings that need to be considered, thus reducing the complexity of invariants.
Synchronization simplifies the verification of asynchronous programs by introducing
the fiction, for proof purposes, that asynchronous operations complete synchronously.
Synchronization summarizes an asynchronous computation as immediate atomic effect.
Inductive sequentialization establishes sequential reductions that captures every
behavior of the original program up to reordering of coarse-grained commutative
actions. A sequential reduction of a concurrent program is easy to reason about
since it corresponds to a simple execution of the program in an idealized synchronous
environment, where processes act in a fixed order and at the same speed.\r\n\r\nOur
approach is implemented the CIVL verifier, which has been successfully used for
the verification of several complex concurrent programs. In our methodology, the
overall correctness of a program is established piecemeal by focusing on the invariant
required for each refinement step separately. While the programmer does the creative
work of specifying the chain of programs and the inductive invariant justifying
each link in the chain, the tool automatically constructs the verification conditions
underlying each refinement step."

text: "We consider dynamical transport metrics for probability measures on discretisations
of a bounded convex domain in ℝd. These metrics are natural discrete counterparts
to the Kantorovich metric \U0001D54E2, defined using a Benamou-Brenier type formula.
Under mild assumptions we prove an asymptotic upper bound for the discrete transport
metric Wt in terms of \U0001D54E2, as the size of the mesh T tends to 0. However,
we show that the corresponding lower bound may fail in general, even on certain
one-dimensional and symmetric two-dimensional meshes. In addition, we show that
the asymptotic lower bound holds under an isotropy assumption on the mesh, which
turns out to be essentially necessary. This assumption is satisfied, e.g., for
tilings by convex regular polygons, and it implies Gromov-Hausdorff convergence
of the transport metric."

text: 'We introduce dynamically warping grids for adaptive liquid simulation. Our
primary contributions are a strategy for dynamically deforming regular grids over
the course of a simulation and a method for efficiently utilizing these deforming
grids for liquid simulation. Prior work has shown that unstructured grids are
very effective for adaptive fluid simulations. However, unstructured grids often
lead to complicated implementations and a poor cache hit rate due to inconsistent
memory access. Regular grids, on the other hand, provide a fast, fixed memory
access pattern and straightforward implementation. Our method combines the advantages
of both: we leverage the simplicity of regular grids while still achieving practical
and controllable spatial adaptivity. We demonstrate that our method enables adaptive
simulations that are fast, flexible, and robust to null-space issues. At the same
time, our method is simple to implement and takes advantage of existing highly-tuned
algorithms.'

text: "The oft-quoted dictum by Arthur Schawlow: ``A diatomic molecule has one atom
too many'' has been disavowed. Inspired by the possibility to experimentally manipulate
and enhance chemical reactivity in helium nanodroplets, we investigate the rotation
of coupled cold molecules in the presence of a many-body environment.\r\nIn this
thesis, we introduce new variational approaches to quantum impurities and apply
them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other
point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed
out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox,
we reveal the self-localization transition for the angulon quasiparticle. We show
that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath
coupling already at the mean-field level. The transition is accompanied by the
spherical-symmetry breaking of the angulon ground state and a discontinuity in
the first derivative of the ground-state energy. Moreover, the type of symmetry
breaking is dictated by the symmetry of the microscopic impurity-bath interaction,
which leads to a number of distinct self-localized states. \r\nFor the system
containing multiple impurities, by analogy with the bipolaron, we introduce the
biangulon quasiparticle describing two rotating molecules that align with respect
to each other due to the effective attractive interaction mediated by the excitations
of the bath. We study this system from the strong-coupling regime to the weak
molecule-bath interaction regime. We show that the molecules tend to have a strong
alignment in the ground state, the biangulon shows shifted angulon instabilities
and an additional spectral instability, where resonant angular momentum transfer
between the molecules and the bath takes place. Finally, we introduce a diagonalization
scheme that allows us to describe the transition from two separated angulons to
a biangulon as a function of the distance between the two molecules."

text: "Form versus function is a long-standing debate in various design-related
fields, such as architecture as well as graphic and industrial design. A good
design that balances form and function often requires considerable human effort
and collaboration among experts from different professional fields. Computational
design tools provide a new paradigm for designing functional objects. In computational
design, form and function are represented as mathematical\r\nquantities, with
the help of numerical and combinatorial algorithms, they can assist even novice
users in designing versatile models that exhibit their desired functionality.
This thesis presents three disparate research studies on the computational design
of functional objects: The appearance of 3d print—we optimize the volumetric material
distribution for faithfully replicating colored surface texture in 3d printing;
the dynamic motion of mechanical structures—\r\nour design system helps the novice
user to retarget various mechanical templates with different functionality to
complex 3d shapes; and a more abstract functionality, multistability—our algorithm
automatically generates models that exhibit multiple stable target poses. For
each of these cases, our computational design tools not only ensure the functionality
of the results but also permit the user aesthetic freedom over the form. Moreover,
fabrication constraints\r\nwere taken into account, which allow for the immediate
creation of physical realization via 3D printing or laser cutting."

text: "Quantum computation enables the execution of algorithms that have exponential
complexity. This might open the path towards the synthesis of new materials or
medical drugs, optimization of transport or financial strategies etc., intractable
on even the fastest classical computers. A quantum computer consists of interconnected
two level quantum systems, called qubits, that satisfy DiVincezo’s criteria. Worldwide,
there are ongoing efforts to find the qubit architecture which will unite quantum
error correction compatible single and two qubit fidelities, long distance qubit
to qubit coupling and \r\n calability. Superconducting qubits have gone the furthest
in this race, demonstrating an algorithm running on 53 coupled qubits, but still
the fidelities are not even close to those required for realizing a single logical
qubit. emiconductor qubits offer extremely good characteristics, but they are
currently investigated across different platforms. Uniting those good characteristics
into a single platform might be a big step towards the quantum computer realization.\r\nHere
we describe the implementation of a hole spin qubit hosted in a Ge hut wire double
quantum dot. The high and tunable spin-orbit coupling together with a heavy hole
state character is expected to allow fast spin manipulation and long coherence
times. Furthermore large lever arms, for hut wire devices, should allow good coupling
to superconducting resonators enabling efficient long distance spin to spin coupling
and a sensitive gate reflectometry spin readout. The developed cryogenic setup
(printed circuit board sample holders, filtering, high-frequency wiring) enabled
us to perform low temperature spin dynamics experiments. Indeed, we measured the
fastest single spin qubit Rabi frequencies reported so far, reaching 140 MHz,
while the dephasing times of 130 ns oppose the long decoherence predictions. In
order to further investigate this, a double quantum dot gate was connected directly
to a lumped element\r\nresonator which enabled gate reflectometry readout. The
vanishing inter-dot transition signal, for increasing external magnetic field,
revealed the spin nature of the measured quantity."

text: We study turn-based stochastic zero-sum games with lexicographic preferences
over reachability and safety objectives. Stochastic games are standard models
in control, verification, and synthesis of stochastic reactive systems that exhibit
both randomness as well as angelic and demonic non-determinism. Lexicographic
order allows to consider multiple objectives with a strict preference order over
the satisfaction of the objectives. To the best of our knowledge, stochastic games
with lexicographic objectives have not been studied before. We establish determinacy
of such games and present strategy and computational complexity results. For strategy
complexity, we show that lexicographically optimal strategies exist that are deterministic
and memory is only required to remember the already satisfied and violated objectives.
For a constant number of objectives, we show that the relevant decision problem
is in NP∩coNP , matching the current known bound for single objectives; and
in general the decision problem is PSPACE -hard and can be solved in NEXPTIME∩coNEXPTIME
. We present an algorithm that computes the lexicographically optimal strategies
via a reduction to computation of optimal strategies in a sequence of single-objectives
games. We have implemented our algorithm and report experimental results on various
case studies.

text: The polymerization–depolymerization dynamics of cytoskeletal proteins play
essential roles in the self-organization of cytoskeletal structures, in eukaryotic
as well as prokaryotic cells. While advances in fluorescence microscopy and in
vitro reconstitution experiments have helped to study the dynamic properties of
these complex systems, methods that allow to collect and analyze large quantitative
datasets of the underlying polymer dynamics are still missing. Here, we present
a novel image analysis workflow to study polymerization dynamics of active filaments
in a nonbiased, highly automated manner. Using treadmilling filaments of the bacterial
tubulin FtsZ as an example, we demonstrate that our method is able to specifically
detect, track and analyze growth and shrinkage of polymers, even in dense networks
of filaments. We believe that this automated method can facilitate the analysis
of a large variety of dynamic cytoskeletal systems, using standard time-lapse
movies obtained from experiments in vitro as well as in the living cell. Moreover,
we provide scripts implementing this method as supplementary material.

text: Most bacteria accomplish cell division with the help of a dynamic protein
complex called the divisome, which spans the cell envelope in the plane of division.
Assembly and activation of this machinery are coordinated by the tubulin-related
GTPase FtsZ, which was found to form treadmilling filaments on supported bilayers
in vitro1, as well as in live cells, in which filaments circle around the cell
division site2,3. Treadmilling of FtsZ is thought to actively move proteins around
the division septum, thereby distributing peptidoglycan synthesis and coordinating
the inward growth of the septum to form the new poles of the daughter cells4.
However, the molecular mechanisms underlying this function are largely unknown.
Here, to study how FtsZ polymerization dynamics are coupled to downstream proteins,
we reconstituted part of the bacterial cell division machinery using its purified
components FtsZ, FtsA and truncated transmembrane proteins essential for cell
division. We found that the membrane-bound cytosolic peptides of FtsN and FtsQ
co-migrated with treadmilling FtsZ–FtsA filaments, but despite their directed
collective behaviour, individual peptides showed random motion and transient confinement.
Our work suggests that divisome proteins follow treadmilling FtsZ filaments by
a diffusion-and-capture mechanism, which can give rise to a moving zone of signalling
activity at the division site.

text: Fejes Tóth [3] studied approximations of smooth surfaces in three-space by
piecewise flat triangular meshes with a given number of vertices on the surface
that are optimal with respect to Hausdorff distance. He proves that this Hausdorff
distance decreases inversely proportional with the number of vertices of the approximating
mesh if the surface is convex. He also claims that this Hausdorff distance is
inversely proportional to the square of the number of vertices for a specific
non-convex surface, namely a one-sheeted hyperboloid of revolution bounded by
two congruent circles. We refute this claim, and show that the asymptotic behavior
of the Hausdorff distance is linear, that is the same as for convex surfaces.

text: 'We study relations between evidence theory and S-approximation spaces. Both
theories have their roots in the analysis of Dempsterchr(''39'')s multivalued
mappings and lower and upper probabilities, and have close relations to rough
sets. We show that an S-approximation space, satisfying a monotonicity condition,
can induce a natural belief structure which is a fundamental block in evidence
theory. We also demonstrate that one can induce a natural belief structure on
one set, given a belief structure on another set, if the two sets are related
by a partial monotone S-approximation space. '

text: The strong rate of convergence of the Euler-Maruyama scheme for nondegenerate
SDEs with irregular drift coefficients is considered. In the case of α-Hölder
drift in the recent literature the rate α/2 was proved in many related situations.
By exploiting the regularising effect of the noise more efficiently, we show that
the rate is in fact arbitrarily close to 1/2 for all α>0. The result extends to
Dini continuous coefficients, while in d=1 also to all bounded measurable coefficients.

text: "Deep neural networks have established a new standard for data-dependent feature
extraction pipelines in the Computer Vision literature. Despite their remarkable
performance in the standard supervised learning scenario, i.e. when models are
trained with labeled data and tested on samples that follow a similar distribution,
neural networks have been shown to struggle with more advanced generalization
abilities, such as transferring knowledge across visually different domains, or
generalizing to new unseen combinations of known concepts. In this thesis we argue
that, in contrast to the usual black-box behavior of neural networks, leveraging
more structured internal representations is a promising direction\r\nfor tackling
such problems. In particular, we focus on two forms of structure. First, we tackle
modularity: We show that (i) compositional architectures are a natural tool for
modeling reasoning tasks, in that they efficiently capture their combinatorial
nature, which is key for generalizing beyond the compositions seen during training.
We investigate how to to learn such models, both formally and experimentally,
for the task of abstract visual reasoning. Then, we show that (ii) in some settings,
modularity allows us to efficiently break down complex tasks into smaller, easier,
modules, thereby improving computational efficiency; We study this behavior in
the context of generative models for colorization, as well as for small objects
detection. Secondly, we investigate the inherently layered structure of representations
learned by neural networks, and analyze its role in the context of transfer learning
and domain adaptation across visually\r\ndissimilar domains. "

text: "Numerous methods have been proposed for probabilistic generative modelling
of\r\n3D objects. However, none of these is able to produce textured objects,
which\r\nrenders them of limited use for practical tasks. In this work, we present
the\r\nfirst generative model of textured 3D meshes. Training such a model would\r\ntraditionally
require a large dataset of textured meshes, but unfortunately,\r\nexisting datasets
of meshes lack detailed textures. We instead propose a new\r\ntraining methodology
that allows learning from collections of 2D images without\r\nany 3D information.
To do so, we train our model to explain a distribution of\r\nimages by modelling
each image as a 3D foreground object placed in front of a\r\n2D background. Thus,
it learns to generate meshes that when rendered, produce\r\nimages similar to
those in its training set.\r\n A well-known problem when generating meshes with
deep networks is the\r\nemergence of self-intersections, which are problematic
for many use-cases. As a\r\nsecond contribution we therefore introduce a new generation
process for 3D\r\nmeshes that guarantees no self-intersections arise, based on
the physical\r\nintuition that faces should push one another out of the way as
they move.\r\n We conduct extensive experiments on our approach, reporting quantitative
and\r\nqualitative results on both synthetic data and natural images. These show
our\r\nmethod successfully learns to generate plausible and diverse textured 3D\r\nsamples
for five challenging object classes."

text: Earlier, we demonstrated that transcript levels of METAL TOLERANCE PROTEIN2
(MTP2) and of HEAVY METAL ATPase2 (HMA2) increase strongly in roots of Arabidopsis
upon prolonged zinc (Zn) deficiency and respond to shoot physiological Zn status,
and not to the local Zn status in roots. This provided evidence for shoot-to-root
communication in the acclimation of plants to Zn deficiency. Zn-deficient soils
limit both the yield and quality of agricultural crops and can result in clinically
relevant nutritional Zn deficiency in human populations. Implementing Zn deficiency
during cultivation of the model plant Arabidopsis thaliana on agar-solidified
media is difficult because trace element contaminations are present in almost
all commercially available agars. Here, we demonstrate root morphological acclimations
to Zn deficiency on agar-solidified medium following the effective removal of
contaminants. These advancements allow reproducible phenotyping toward understanding
fundamental plant responses to deficiencies of Zn and other essential trace elements.

text: 'Retrovirus assembly is driven by the multidomain structural protein Gag.
Interactions between the capsid domains (CA) of Gag result in Gag multimerization,
leading to an immature virus particle that is formed by a protein lattice based
on dimeric, trimeric, and hexameric protein contacts. Among retroviruses the inter-
and intra-hexamer contacts differ, especially in the N-terminal sub-domain of
CA (CANTD). For HIV-1 the cellular molecule inositol hexakisphosphate (IP6) interacts
with and stabilizes the immature hexamer, and is required for production of infectious
virus particles. We have used in vitro assembly, cryo-electron tomography and
subtomogram averaging, atomistic molecular dynamics simulations and mutational
analyses to study the HIV-related lentivirus equine infectious anemia virus (EIAV).
In particular, we sought to understand the structural conservation of the immature
lentivirus lattice and the role of IP6 in EIAV assembly. Similar to HIV-1, IP6
strongly promoted in vitro assembly of EIAV Gag proteins into virus-like particles
(VLPs), which took three morphologically highly distinct forms: narrow tubes,
wide tubes, and spheres. Structural characterization of these VLPs to sub-4Å resolution
unexpectedly showed that all three morphologies are based on an immature lattice
with preserved key structural components, highlighting the structural versatility
of CA to form immature assemblies. A direct comparison between EIAV and HIV revealed
that both lentiviruses maintain similar immature interfaces, which are established
by both conserved and non-conserved residues. In both EIAV and HIV-1, IP6 regulates
immature assembly via conserved lysine residues within the CACTD and SP. Lastly,
we demonstrate that IP6 stimulates in vitro assembly of immature particles of
several other retroviruses in the lentivirus genus, suggesting a conserved role
for IP6 in lentiviral assembly.'

text: The fixation probability of a single mutant invading a population of residents
is among the most widely-studied quantities in evolutionary dynamics. Amplifiers
of natural selection are population structures that increase the fixation probability
of advantageous mutants, compared to well-mixed populations. Extensive studies
have shown that many amplifiers exist for the Birth-death Moran process, some
of them substantially increasing the fixation probability or even guaranteeing
fixation in the limit of large population size. On the other hand, no amplifiers
are known for the death-Birth Moran process, and computer-assisted exhaustive
searches have failed to discover amplification. In this work we resolve this disparity,
by showing that any amplification under death-Birth updating is necessarily bounded
and transient. Our boundedness result states that even if a population structure
does amplify selection, the resulting fixation probability is close to that of
the well-mixed population. Our transience result states that for any population
structure there exists a threshold r⋆ such that the population structure ceases
to amplify selection if the mutant fitness advantage r is larger than r⋆. Finally,
we also extend the above results to δ-death-Birth updating, which is a combination
of Birth-death and death-Birth updating. On the positive side, we identify population
structures that maintain amplification for a wide range of values r and δ. These
results demonstrate that amplification of natural selection depends on the specific
mechanisms of the evolutionary process.

text: 'In this thesis we study certain mathematical aspects of evolution. The two
primary forces that drive an evolutionary process are mutation and selection.
Mutation generates new variants in a population. Selection chooses among the variants
depending on the reproductive rates of individuals. Evolutionary processes are
intrinsically random – a new mutation that is initially present in the population
at low frequency can go extinct, even if it confers a reproductive advantage.
The overall rate of evolution is largely determined by two quantities: the probability
that an invading advantageous mutation spreads through the population (called
fixation probability) and the time until it does so (called fixation time). Both
those quantities crucially depend not only on the strength of the invading mutation
but also on the population structure. In this thesis, we aim to understand how
the underlying population structure affects the overall rate of evolution. Specifically,
we study population structures that increase the fixation probability of advantageous
mutants (called amplifiers of selection). Broadly speaking, our results are of
three different types: We present various strong amplifiers, we identify regimes
under which only limited amplification is feasible, and we propose population
structures that provide different tradeoffs between high fixation probability
and short fixation time.'

text: "The optimization of multilayer neural networks typically leads to a solution\r\nwith
zero training error, yet the landscape can exhibit spurious local minima\r\nand
the minima can be disconnected. In this paper, we shed light on this\r\nphenomenon:
we show that the combination of stochastic gradient descent (SGD)\r\nand over-parameterization
makes the landscape of multilayer neural networks\r\napproximately connected and
thus more favorable to optimization. More\r\nspecifically, we prove that SGD solutions
are connected via a piecewise linear\r\npath, and the increase in loss along this
path vanishes as the number of\r\nneurons grows large. This result is a consequence
of the fact that the\r\nparameters found by SGD are increasingly dropout stable
as the network becomes\r\nwider. We show that, if we remove part of the neurons
(and suitably rescale the\r\nremaining ones), the change in loss is independent
of the total number of\r\nneurons, and it depends only on how many neurons are
left. Our results exhibit\r\na mild dependence on the input dimension: they are
dimension-free for two-layer\r\nnetworks and depend linearly on the dimension
for multilayer networks. We\r\nvalidate our theoretical findings with numerical
experiments for different\r\narchitectures and classification tasks."

text: Representing an atom by a solid sphere in 3-dimensional Euclidean space, we
get the space-filling diagram of a molecule by taking the union. Molecular dynamics
simulates its motion subject to bonds and other forces, including the solvation
free energy. The morphometric approach [12, 17] writes the latter as a linear
combination of weighted versions of the volume, area, mean curvature, and Gaussian
curvature of the space-filling diagram. We give a formula for the derivative of
the weighted mean curvature. Together with the derivatives of the weighted volume
in [7], the weighted area in [3], and the weighted Gaussian curvature [1], this
yields the derivative of the morphometric expression of the solvation free energy.

of the weighted\r\ncurvature derivatives for the purpose of improving molecular
dynamics simulations and for his continued encouragement. They also thank Patrice
Koehl for the implementation of the formulas and for his encouragement and advise

criticism.\r\nThis project has received funding from the European Research Council

text: We consider the symmetric simple exclusion process in Zd with quenched bounded
dynamic random conductances and prove its hydrodynamic limit in path space. The
main tool is the connection, due to the self-duality of the process, between the
invariance principle for single particles starting from all points and the macroscopic
behavior of the density field. While the hydrodynamic limit at fixed macroscopic
times is obtained via a generalization to the time-inhomogeneous context of the
strategy introduced in [41], in order to prove tightness for the sequence of empirical
density fields we develop a new criterion based on the notion of uniform conditional
stochastic continuity, following [50]. In conclusion, we show that uniform elliptic
dynamic conductances provide an example of environments in which the so-called
arbitrary starting point invariance principle may be derived from the invariance
principle of a single particle starting from the origin. Therefore, our hydrodynamics
result applies to the examples of quenched environments considered in, e.g., [1],
[3], [6] in combination with the hypothesis of uniform ellipticity.

text: An asymptotic formula is established for the number of rational points of
bounded anticanonical height which lie on a certain Zariski dense subset of the
biprojective hypersurface x1y21+⋯+x4y24=0 in ℙ3×ℙ3. This confirms the modified
Manin conjecture for this variety, in which the removal of a thin set of rational
points is allowed.

text: We demonstrate the utility of optical cavity generated spin-squeezed states
in free space atomic fountain clocks in ensembles of 390 000 87Rb atoms. Fluorescence
imaging, correlated to an initial quantum nondemolition measurement, is used for
population spectroscopy after the atoms are released from a confining lattice.
For a free fall time of 4 milliseconds, we resolve a single-shot phase sensitivity
of 814(61) microradians, which is 5.8(0.6) decibels (dB) below the quantum projection
limit. We observe that this squeezing is preserved as the cloud expands to a roughly
200 μm radius and falls roughly 300 μm in free space. Ramsey spectroscopy with
240 000 atoms at a 3.6 ms Ramsey time results in a single-shot fractional frequency
stability of 8.4(0.2)×10−12, 3.8(0.2) dB below the quantum projection limit. The
sensitivity and stability are limited by the technical noise in the fluorescence
detection protocol and the microwave system, respectively.

text: The search for biologically faithful synaptic plasticity rules has resulted
in a large body of models. They are usually inspired by – and fitted to – experimental
data, but they rarely produce neural dynamics that serve complex functions. These
failures suggest that current plasticity models are still under-constrained by
existing data. Here, we present an alternative approach that uses meta-learning
to discover plausible synaptic plasticity rules. Instead of experimental data,
the rules are constrained by the functions they implement and the structure they
are meant to produce. Briefly, we parameterize synaptic plasticity rules by a
Volterra expansion and then use supervised learning methods (gradient descent
or evolutionary strategies) to minimize a problem-dependent loss function that
quantifies how effectively a candidate plasticity rule transforms an initially
random network into one with the desired function. We first validate our approach
by re-discovering previously described plasticity rules, starting at the single-neuron
level and “Oja’s rule”, a simple Hebbian plasticity rule that captures the direction
of most variability of inputs to a neuron (i.e., the first principal component).
We expand the problem to the network level and ask the framework to find Oja’s
rule together with an anti-Hebbian rule such that an initially random two-layer
firing-rate network will recover several principal components of the input space
after learning. Next, we move to networks of integrate-and-fire neurons with plastic
inhibitory afferents. We train for rules that achieve a target firing rate by
countering tuned excitation. Our algorithm discovers a specific subset of the
manifold of rules that can solve this task. Our work is a proof of principle of
an automated and unbiased approach to unveil synaptic plasticity rules that obey
biological constraints and can solve complex functions.

text: The widely used non-steroidal anti-inflammatory drugs (NSAIDs) are derivatives
of the phytohormone salicylic acid (SA). SA is well known to regulate plant immunity
and development, whereas there have been few reports focusing on the effects of
NSAIDs in plants. Our studies here reveal that NSAIDs exhibit largely overlapping
physiological activities to SA in the model plant Arabidopsis. NSAID treatments
lead to shorter and agravitropic primary roots and inhibited lateral root organogenesis.
Notably, in addition to the SA-like action, which in roots involves binding to
the protein phosphatase 2A (PP2A), NSAIDs also exhibit PP2A-independent effects.
Cell biological and biochemical analyses reveal that many NSAIDs bind directly
to and inhibit the chaperone activity of TWISTED DWARF1, thereby regulating actin
cytoskeleton dynamics and subsequent endosomal trafficking. Our findings uncover
an unexpected bioactivity of human pharmaceuticals in plants and provide insights
into the molecular mechanism underlying the cellular action of this class of anti-inflammatory
compounds.

text: Pulsating flows through tubular geometries are laminar provided that velocities
are moderate. This in particular is also believed to apply to cardiovascular flows
where inertial forces are typically too low to sustain turbulence. On the other
hand, flow instabilities and fluctuating shear stresses are held responsible for
a variety of cardiovascular diseases. Here we report a nonlinear instability mechanism
for pulsating pipe flow that gives rise to bursts of turbulence at low flow rates.
Geometrical distortions of small, yet finite, amplitude are found to excite a
state consisting of helical vortices during flow deceleration. The resulting flow
pattern grows rapidly in magnitude, breaks down into turbulence, and eventually
returns to laminar when the flow accelerates. This scenario causes shear stress
fluctuations and flow reversal during each pulsation cycle. Such unsteady conditions
can adversely affect blood vessels and have been shown to promote inflammation
and dysfunction of the shear stress-sensitive endothelial cell layer.

text: We study the unique solution m of the Dyson equation \( -m(z)^{-1} = z\1 -
a + S[m(z)] \) on a von Neumann algebra A with the constraint Imm≥0. Here, z lies
in the complex upper half-plane, a is a self-adjoint element of A and S is a positivity-preserving
linear operator on A. We show that m is the Stieltjes transform of a compactly
supported A-valued measure on R. Under suitable assumptions, we establish that
this measure has a uniformly 1/3-Hölder continuous density with respect to the
Lebesgue measure, which is supported on finitely many intervals, called bands.
In fact, the density is analytic inside the bands with a square-root growth at
the edges and internal cubic root cusps whenever the gap between two bands vanishes.
The shape of these singularities is universal and no other singularity may occur.
We give a precise asymptotic description of m near the singular points. These
asymptotics generalize the analysis at the regular edges given in the companion
paper on the Tracy-Widom universality for the edge eigenvalue statistics for correlated
random matrices [the first author et al., Ann. Probab. 48, No. 2, 963--1001 (2020;
Zbl 1434.60017)] and they play a key role in the proof of the Pearcey universality
at the cusp for Wigner-type matrices [G. Cipolloni et al., Pure Appl. Anal. 1,
No. 4, 615--707 (2019; Zbl 07142203); the second author et al., Commun. Math.
Phys. 378, No. 2, 1203--1278 (2020; Zbl 07236118)]. We also extend the finite
dimensional band mass formula from [the first author et al., loc. cit.] to the
von Neumann algebra setting by showing that the spectral mass of the bands is
topologically rigid under deformations and we conclude that these masses are quantized
in some important cases.

text: 'We present solutions to several problems originating from geometry and discrete
mathematics: existence of equipartitions, maps without Tverberg multiple points,
and inscribing quadrilaterals. Equivariant obstruction theory is the natural topological
approach to these type of questions. However, for the specific problems we consider
it had yielded only partial or no results. We get our results by complementing
equivariant obstruction theory with other techniques from topology and geometry.'

text: We give the first mathematically rigorous justification of the local density
approximation in density functional theory. We provide a quantitative estimate
on the difference between the grand-canonical Levy–Lieb energy of a given density
(the lowest possible energy of all quantum states having this density) and the
integral over the uniform electron gas energy of this density. The error involves
gradient terms and justifies the use of the local density approximation in the
situation where the density is very flat on sufficiently large regions in space.

text: Amyotrophic lateral sclerosis (ALS) leads to a loss of specific motor neuron
populations in the spinal cord and cortex. Emerging evidence suggests that interneurons
may also be affected, but a detailed characterization of interneuron loss and
its potential impacts on motor neuron loss and disease progression is lacking.
To examine this issue, the fate of V1 inhibitory neurons during ALS was assessed
in the ventral spinal cord using the SODG93A mouse model. The V1 population makes
up ∼30% of all ventral inhibitory neurons, ∼50% of direct inhibitory synaptic
contacts onto motor neuron cell bodies, and is thought to play a key role in modulating
motor output, in part through recurrent and reciprocal inhibitory circuits. We
find that approximately half of V1 inhibitory neurons are lost in SODG93A mice
at late disease stages, but that this loss is delayed relative to the loss of
motor neurons and V2a excitatory neurons. We further identify V1 subpopulations
based on transcription factor expression that are differentially susceptible to
degeneration in SODG93A mice. At an early disease stage, we show that V1 synaptic
contacts with motor neuron cell bodies increase, suggesting an upregulation of
inhibition before V1 neurons are lost in substantial numbers. These data support
a model in which progressive changes in V1 synaptic contacts early in disease,
and in select V1 subpopulations at later stages, represent a compensatory upregulation
and then deleterious breakdown of specific interneuron circuits within the spinal
cord.

text: 'Antibiotics that interfere with translation, when combined, interact in diverse
and difficult-to-predict ways. Here, we explain these interactions by "translation
bottlenecks": points in the translation cycle where antibiotics block ribosomal
progression. To elucidate the underlying mechanisms of drug interactions between
translation inhibitors, we generate translation bottlenecks genetically using
inducible control of translation factors that regulate well-defined translation
cycle steps. These perturbations accurately mimic antibiotic action and drug interactions,
supporting that the interplay of different translation bottlenecks causes these
interactions. We further show that growth laws, combined with drug uptake and
binding kinetics, enable the direct prediction of a large fraction of observed
interactions, yet fail to predict suppression. However, varying two translation
bottlenecks simultaneously supports that dense traffic of ribosomes and competition
for translation factors account for the previously unexplained suppression. These
results highlight the importance of "continuous epistasis" in bacterial physiology.'

text: Semiconductor nanowires have been playing a crucial role in the development
of nanoscale devices for the realization of spin qubits, Majorana fermions, single
photon emitters, nanoprocessors, etc. The monolithic growth of site‐controlled
nanowires is a prerequisite toward the next generation of devices that will require
addressability and scalability. Here, combining top‐down nanofabrication and bottom‐up
self‐assembly, the growth of Ge wires on prepatterned Si (001) substrates with
controllable position, distance, length, and structure is reported. This is achieved
by a novel growth process that uses a SiGe strain‐relaxation template and can
be potentially generalized to other material combinations. Transport measurements
show an electrically tunable spin–orbit coupling, with a spin–orbit length similar
to that of III–V materials. Also, charge sensing between quantum dots in closely
spaced wires is observed, which underlines their potential for the realization
of advanced quantum devices. The reported results open a path toward scalable
qubit devices using nanowires on silicon.

text: Phenomenological relations such as Ohm’s or Fourier’s law have a venerable
history in physics but are still scarce in biology. This situation restrains predictive
theory. Here, we build on bacterial “growth laws,” which capture physiological
feedback between translation and cell growth, to construct a minimal biophysical
model for the combined action of ribosome-targeting antibiotics. Our model predicts
drug interactions like antagonism or synergy solely from responses to individual
drugs. We provide analytical results for limiting cases, which agree well with
numerical results. We systematically refine the model by including direct physical
interactions of different antibiotics on the ribosome. In a limiting case, our
model provides a mechanistic underpinning for recent predictions of higher-order
interactions that were derived using entropy maximization. We further refine the
model to include the effects of antibiotics that mimic starvation and the presence
of resistance genes. We describe the impact of a starvation-mimicking antibiotic
on drug interactions analytically and verify it experimentally. Our extended model
suggests a change in the type of drug interaction that depends on the strength
of resistance, which challenges established rescaling paradigms. We experimentally
show that the presence of unregulated resistance genes can lead to altered drug
interaction, which agrees with the prediction of the model. While minimal, the
model is readily adaptable and opens the door to predicting interactions of second
and higher-order in a broad range of biological systems.

text: Gene expression levels are influenced by multiple coexisting molecular mechanisms.
Some of these interactions, such as those of transcription factors and promoters
have been studied extensively. However, predicting phenotypes of gene regulatory
networks remains a major challenge. Here, we use a well-defined synthetic gene
regulatory network to study how network phenotypes depend on local genetic context,
i.e. the genetic neighborhood of a transcription factor and its relative position.
We show that one gene regulatory network with fixed topology can display not only
quantitatively but also qualitatively different phenotypes, depending solely on
the local genetic context of its components. Our results demonstrate that changes
in local genetic context can place a single transcriptional unit within two separate
regulons without the need for complex regulatory sequences. We propose that relative
order of individual transcriptional units, with its potential for combinatorial
complexity, plays an important role in shaping phenotypes of gene regulatory networks.

text: Organisms cope with change by employing transcriptional regulators. However,
when faced with rare environments, the evolution of transcriptional regulators
and their promoters may be too slow. We ask whether the intrinsic instability
of gene duplication and amplification provides a generic alternative to canonical
gene regulation. By real-time monitoring of gene copy number mutations in E. coli,
we show that gene duplications and amplifications enable adaptation to fluctuating
environments by rapidly generating copy number, and hence expression level, polymorphism.
This ‘amplification-mediated gene expression tuning’ occurs on timescales similar
to canonical gene regulation and can deal with rapid environmental changes. Mathematical
modeling shows that amplifications also tune gene expression in stochastic environments
where transcription factor-based schemes are hard to evolve or maintain. The fleeting
nature of gene amplifications gives rise to a generic population-level mechanism
that relies on genetic heterogeneity to rapidly tune expression of any gene, without
leaving any genomic signature.

text: "Fabrication of curved shells plays an important role in modern design, industry,
and science. Among their remarkable properties are, for example, aesthetics of
organic shapes, ability to evenly distribute loads, or efficient flow separation.
They find applications across vast length scales ranging from sky-scraper architecture
to microscopic devices. But, at\r\nthe same time, the design of curved shells
and their manufacturing process pose a variety of challenges. In this thesis,
they are addressed from several perspectives. In particular, this thesis presents
approaches based on the transformation of initially flat sheets into the target
curved surfaces. This involves problems of interactive design of shells with nontrivial
mechanical constraints, inverse design of complex structural materials, and data-driven
modeling of delicate and time-dependent physical properties. At the same time,
two newly-developed self-morphing mechanisms targeting flat-to-curved transformation
are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold
bent glass panelizations. Originally flat glass panels are bent into frames and
remain stressed. This is a cost-efficient fabrication approach compared to hot
bending, when glass panels are shaped plastically. However such constructions
are prone to breaking during bending, and it is highly\r\nnontrivial to navigate
the design space, keeping the panels fabricable and aesthetically pleasing at
the same time. We introduce an interactive design system for cold bent glass façades,
while previously even offline optimization for such scenarios has not been sufficiently
developed. Our method is based on a deep learning approach providing quick\r\nand
high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication
of smaller objects of scales below 1 m, can also greatly benefit from shaping
originally flat sheets. In this respect, we designed new self-morphing shell mechanisms
transforming from an initial flat state to a doubly curved state with high precision
and detail. Our so-called CurveUps demonstrate the encodement of the geometric
information\r\ninto the shell. Furthermore, we explored the frontiers of programmable
materials and showed how temporal information can additionally be encoded into
a flat shell. This allows prescribing deformation sequences for doubly curved
surfaces and, thus, facilitates self-collision avoidance enabling complex shapes
and functionalities otherwise impossible.\r\nBoth of these methods include inverse
design tools keeping the user in the design loop."

text: "Cold bent glass is a promising and cost-efficient method for realizing doubly
curved glass facades. They are produced by attaching planar glass sheets to curved
frames and require keeping the occurring stress within safe limits.\r\nHowever,
it is very challenging to navigate the design space of cold bent glass panels
due to the fragility of the material, which impedes the form-finding for practically
feasible and aesthetically pleasing cold bent glass facades. We propose an interactive,
data-driven approach for designing cold bent glass facades that can be seamlessly
integrated into a typical architectural design pipeline. Our method allows non-expert
users to interactively edit a parametric surface while providing real-time feedback
on the deformed shape and maximum stress of cold bent glass panels. Designs are
automatically refined to minimize several fairness criteria while maximal stresses
are kept within glass limits. We achieve interactive frame rates by using a differentiable
Mixture Density Network trained from more than a million simulations. Given a
curved boundary, our regression model is capable of handling multistable\r\nconfigurations
and accurately predicting the equilibrium shape of the panel and its corresponding
maximal stress. We show predictions are highly accurate and validate our results
with a physical realization of a cold bent glass surface."

text: Using inelastic cotunneling spectroscopy we observe a zero field splitting
within the spin triplet manifold of Ge hut wire quantum dots. The states with
spin ±1 in the confinement direction are energetically favored by up to 55 μeV
compared to the spin 0 triplet state because of the strong spin–orbit coupling.
The reported effect should be observable in a broad class of strongly confined
hole quantum-dot systems and might need to be considered when operating hole spin
qubits.

text: In vitro work revealed that excitatory synaptic inputs to hippocampal inhibitory
interneurons could undergo Hebbian, associative, or non-associative plasticity.
Both behavioral and learning-dependent reorganization of these connections has
also been demonstrated by measuring spike transmission probabilities in pyramidal
cell-interneuron spike cross-correlations that indicate monosynaptic connections.
Here we investigated the activity-dependent modification of these connections
during exploratory behavior in rats by optogenetically inhibiting pyramidal cell
and interneuron subpopulations. Light application and associated firing alteration
of pyramidal and interneuron populations led to lasting changes in pyramidal-interneuron
connection weights as indicated by spike transmission changes. Spike transmission
alterations were predicted by the light-mediated changes in the number of pre-
and postsynaptic spike pairing events and by firing rate changes of interneurons
but not pyramidal cells. This work demonstrates the presence of activity-dependent
associative and non-associative reorganization of pyramidal-interneuron connections
triggered by the optogenetic modification of the firing rate and spike synchrony
of cells.

text: Advances in shape-morphing materials, such as hydrogels, shape-memory polymers
and light-responsive polymers have enabled prescribing self-directed deformations
of initially flat geometries. However, most proposed solutions evolve towards
a target geometry without considering time-dependent actuation paths. To achieve
more complex geometries and avoid self-collisions, it is critical to encode a
spatial and temporal shape evolution within the initially flat shell. Recent realizations
of time-dependent morphing are limited to the actuation of few, discrete hinges
and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding
temporal shape evolution in architected shells that assume complex shapes and
doubly curved geometries. The shells are non-periodic tessellations of pre-stressed
contractile unit cells that soften in water at rates prescribed locally by mesostructure
geometry. The ensuing midplane contraction is coupled to the formation of encoded
curvatures. We propose an inverse design tool based on a data-driven model for
unit cells’ temporal responses.

text: Cryo-electron microscopy (cryo-EM) of cellular specimens provides insights
into biological processes and structures within a native context. However, a major
challenge still lies in the efficient and reproducible preparation of adherent
cells for subsequent cryo-EM analysis. This is due to the sensitivity of many
cellular specimens to the varying seeding and culturing conditions required for
EM experiments, the often limited amount of cellular material and also the fragility
of EM grids and their substrate. Here, we present low-cost and reusable 3D printed
grid holders, designed to improve specimen preparation when culturing challenging
cellular samples directly on grids. The described grid holders increase cell culture
reproducibility and throughput, and reduce the resources required for cell culturing.
We show that grid holders can be integrated into various cryo-EM workflows, including
micro-patterning approaches to control cell seeding on grids, and for generating
samples for cryo-focused ion beam milling and cryo-electron tomography experiments.
Their adaptable design allows for the generation of specialized grid holders customized
to a large variety of applications.

text: Persistent homology is a powerful tool in Topological Data Analysis (TDA)
to capture the topological properties of data succinctly at different spatial
resolutions. For graphical data, the shape, and structure of the neighborhood
of individual data items (nodes) are an essential means of characterizing their
properties. We propose the use of persistent homology methods to capture structural
and topological properties of graphs and use it to address the problem of link
prediction. We achieve encouraging results on nine different real-world datasets
that attest to the potential of persistent homology-based methods for network
analysis.

text: In this paper, we present the first Asynchronous Distributed Key Generation
(ADKG) algorithm which is also the first distributed key generation algorithm
that can generate cryptographic keys with a dual (f,2f+1)-threshold (where f is
the number of faulty parties). As a result, using our ADKG we remove the trusted
setup assumption that the most scalable consensus algorithms make. In order to
create a DKG with a dual (f,2f+1)- threshold we first answer in the affirmative

text: We propose a novel hybridization method for stability analysis that over-approximates
nonlinear dynamical systems by switched systems with linear inclusion dynamics.
We observe that existing hybridization techniques for safety analysis that over-approximate
nonlinear dynamical systems by switched affine inclusion dynamics and provide
fixed approximation error, do not suffice for stability analysis. Hence, we propose
a hybridization method that provides a state-dependent error which converges to
zero as the state tends to the equilibrium point. The crux of our hybridization
computation is an elegant recursive algorithm that uses partial derivatives of
a given function to obtain upper and lower bound matrices for the over-approximating
linear inclusion. We illustrate our method on some examples to demonstrate the
application of the theory for stability analysis. In particular, our method is
able to establish stability of a nonlinear system which does not admit a polynomial
Lyapunov function.

text: We consider systems of bosons trapped in a box, in the Gross–Pitaevskii regime.
We show that low-energy states exhibit complete Bose–Einstein condensation with
an optimal bound on the number of orthogonal excitations. This extends recent
results obtained in Boccato et al. (Commun Math Phys 359(3):975–1026, 2018), removing
the assumption of small interaction potential.

text: 'We study the problem of automatically detecting if a given multi-class classifier
operates outside of its specifications (out-of-specs), i.e. on input data from
a different distribution than what it was trained for. This is an important problem
to solve on the road towards creating reliable computer vision systems for real-world
applications, because the quality of a classifier’s predictions cannot be guaranteed
if it operates out-of-specs. Previously proposed methods for out-of-specs detection
make decisions on the level of single inputs. This, however, is insufficient to
achieve low false positive rate and high false negative rates at the same time.
In this work, we describe a new procedure named KS(conf), based on statistical
reasoning. Its main component is a classical Kolmogorov–Smirnov test that is applied
to the set of predicted confidence values for batches of samples. Working with
batches instead of single samples allows increasing the true positive rate without
negatively affecting the false positive rate, thereby overcoming a crucial limitation
of single sample tests. We show by extensive experiments using a variety of convolutional
network architectures and datasets that KS(conf) reliably detects out-of-specs
situations even under conditions where other tests fail. It furthermore has a
number of properties that make it an excellent candidate for practical deployment:
it is easy to implement, adds almost no overhead to the system, works with any
classifier that outputs confidence scores, and requires no a priori knowledge
about how the data distribution could change.'

text: The notion of program sensitivity (aka Lipschitz continuity) specifies that
changes in the program input result in proportional changes to the program output.
For probabilistic programs the notion is naturally extended to expected sensitivity.
A previous approach develops a relational program logic framework for proving
expected sensitivity of probabilistic while loops, where the number of iterations
is fixed and bounded. In this work, we consider probabilistic while loops where
the number of iterations is not fixed, but randomized and depends on the initial
input values. We present a sound approach for proving expected sensitivity of
such programs. Our sound approach is martingale-based and can be automated through
existing martingale-synthesis algorithms. Furthermore, our approach is compositional
for sequential composition of while loops under a mild side condition. We demonstrate
the effectiveness of our approach on several classical examples from Gambler's
Ruin, stochastic hybrid systems and stochastic gradient descent. We also present
experimental results showing that our automated approach can handle various probabilistic
programs in the literature.

text: We prove edge universality for a general class of correlated real symmetric
or complex Hermitian Wigner matrices with arbitrary expectation. Our theorem also
applies to internal edges of the self-consistent density of states. In particular,
we establish a strong form of band rigidity which excludes mismatches between
location and label of eigenvalues close to internal edges in these general models.

text: Protein abundance and localization at the plasma membrane (PM) shapes plant
development and mediates adaptation to changing environmental conditions. It is
regulated by ubiquitination, a post-translational modification crucial for the
proper sorting of endocytosed PM proteins to the vacuole for subsequent degradation.
To understand the significance and the variety of roles played by this reversible
modification, the function of ubiquitin receptors, which translate the ubiquitin
signature into a cellular response, needs to be elucidated. In this study, we
show that TOL (TOM1-like) proteins function in plants as multivalent ubiquitin
receptors, governing ubiquitinated cargo delivery to the vacuole via the conserved
Endosomal Sorting Complex Required for Transport (ESCRT) pathway. TOL2 and TOL6
interact with components of the ESCRT machinery and bind to K63-linked ubiquitin
via two tandemly arranged conserved ubiquitin-binding domains. Mutation of these
domains results not only in a loss of ubiquitin binding but also altered localization,
abolishing TOL6 ubiquitin receptor activity. Function and localization of TOL6
is itself regulated by ubiquitination, whereby TOL6 ubiquitination potentially
modulates degradation of PM-localized cargoes, assisting in the fine-tuning of
the delicate interplay between protein recycling and downregulation. Taken together,
our findings demonstrate the function and regulation of a ubiquitin receptor that
mediates vacuolar degradation of PM proteins in higher plants.

text: The assembly of a septin filament requires that homologous monomers must distinguish
between one another in establishing appropriate interfaces with their neighbors.
To understand this phenomenon at the molecular level, we present the first four
crystal structures of heterodimeric septin complexes. We describe in detail the
two distinct types of G-interface present within the octameric particles, which
must polymerize to form filaments. These are formed between SEPT2 and SEPT6 and
between SEPT7 and SEPT3, and their description permits an understanding of the
structural basis for the selectivity necessary for correct filament assembly.
By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's
postulate, which predicts the exchangeability of septins from within a subgroup.
Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent
conformational change, have been repurposed in septins to play a fundamental role
in molecular recognition. Specifically, it is switch I which holds the key to
discriminating between the two different G-interfaces. Moreover, residues which
are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing
that the correct interfaces are formed.

text: Previous research on animations of soap bubbles, films, and foams largely
focuses on the motion and geometric shape of the bubble surface. These works neglect
the evolution of the bubble’s thickness, which is normally responsible for visual
phenomena like surface vortices, Newton’s interference patterns, capillary waves,
and deformation-dependent rupturing of films in a foam. In this paper, we model
these natural phenomena by introducing the film thickness as a reduced degree
of freedom in the Navier-Stokes equations and deriving their equations of motion.
We discretize the equations on a nonmanifold triangle mesh surface and couple
it to an existing bubble solver. In doing so, we also introduce an incompressible
fluid solver for 2.5D films and a novel advection algorithm for convecting fields
across non-manifold surface junctions. Our simulations enhance state-of-the-art
bubble solvers with additional effects caused by convection, rippling, draining,
and evaporation of the thin film.

text: "The Massively Parallel Computation (MPC) model is an emerging model which
distills core aspects of distributed and parallel computation. It has been developed
as a tool to solve (typically graph) problems in systems where the input is distributed
over many machines with limited space.\r\n\t\r\nRecent work has focused on the
regime in which machines have sublinear (in $n$, the number of nodes in the input
graph) space, with randomized algorithms presented for fundamental graph problems
of Maximal Matching and Maximal Independent Set. However, there have been no prior
corresponding deterministic algorithms.\r\n\t\r\n\tA major challenge underlying
the sublinear space setting is that the local space of each machine might be too
small to store all the edges incident to a single node. This poses a considerable
obstacle compared to the classical models in which each node is assumed to know
and have easy access to its incident edges. To overcome this barrier we introduce
a new graph sparsification technique that deterministically computes a low-degree
subgraph with additional desired properties. The degree of the nodes in this subgraph
is small in the sense that the edges of each node can be now stored on a single
machine. This low-degree subgraph also has the property that solving the problem
on this subgraph provides \\emph{significant} global progress, i.e., progress
towards solving the problem for the original input graph.\r\n\t\r\nUsing this
framework to derandomize the well-known randomized algorithm of Luby [SICOMP'86],
we obtain $O(\\log \\Delta+\\log\\log n)$-round deterministic MPC algorithms for
solving the fundamental problems of Maximal Matching and Maximal Independent Set
with $O(n^{\\epsilon})$ space on each machine for any constant $\\epsilon > 0$.
Based on the recent work of Ghaffari et al. [FOCS'18], this additive $O(\\log\\log
n)$ factor is conditionally essential. These algorithms can also be shown to run
in $O(\\log \\Delta)$ rounds in the closely related model of CONGESTED CLIQUE,
improving upon the state-of-the-art bound of $O(\\log^2 \\Delta)$ rounds by Censor-Hillel
et al. [DISC'17]."

text: "Balanced search trees typically use key comparisons to guide their operations,
and achieve logarithmic running time. By relying on numerical properties of the
keys, interpolation search achieves lower search complexity and better performance.
Although interpolation-based data structures were investigated in the past, their
non-blocking concurrent variants have received very little attention so far.\r\nIn
this paper, we propose the first non-blocking implementation of the classic interpolation
search tree (IST) data structure. For arbitrary key distributions, the data structure
ensures worst-case O(log n + p) amortized time for search, insertion and deletion
traversals. When the input key distributions are smooth, lookups run in expected
O(log log n + p) time, and insertion and deletion run in expected amortized O(log
log n + p) time, where p is a bound on the number of threads. To improve the scalability
of concurrent insertion and deletion, we propose a novel parallel rebuilding technique,
which should be of independent interest.\r\nWe evaluate whether the theoretical
improvements translate to practice by implementing the concurrent interpolation
search tree, and benchmarking it on uniform and nonuniform key distributions,
for dataset sizes in the millions to billions of keys. Relative to the state-of-the-art
concurrent data structures, the concurrent interpolation search tree achieves
performance improvements of up to 15% under high update rates, and of up to 50%
under moderate update rates. Further, ISTs exhibit up to 2X less cache-misses,
and consume 1.2 -- 2.6X less memory compared to the next best alternative on typical
dataset sizes. We find that the results are surprisingly robust to distributional
skew, which suggests that our data structure can be a promising alternative to
classic concurrent search structures."

text: 'We present a method for animating yarn-level cloth effects using a thin-shell
solver. We accomplish this through numerical homogenization: we first use a large
number of yarn-level simulations to build a model of the potential energy density
of the cloth, and then use this energy density function to compute forces in a
thin shell simulator. We model several yarn-based materials, including both woven
and knitted fabrics. Our model faithfully reproduces expected effects like the
stiffness of woven fabrics, and the highly deformable nature and anisotropy of
knitted fabrics. Our approach does not require any real-world experiments nor
measurements; because the method is based entirely on simulations, it can generate
entirely new material models quickly, without the need for testing apparatuses
or human intervention. We provide data-driven models of several woven and knitted
fabrics, which can be used for efficient simulation with an off-the-shelf cloth
solver.'

text: When short-range attractions are combined with long-range repulsions in colloidal
particle systems, complex microphases can emerge. Here, we study a system of isotropic
particles, which can form lamellar structures or a disordered fluid phase when
temperature is varied. We show that, at equilibrium, the lamellar structure crystallizes,
while out of equilibrium, the system forms a variety of structures at different
shear rates and temperatures above melting. The shear-induced ordering is analyzed
by means of principal component analysis and artificial neural networks, which
are applied to data of reduced dimensionality. Our results reveal the possibility
of inducing ordering by shear, potentially providing a feasible route to the fabrication
of ordered lamellar structures from isotropic particles.

text: We present the first deterministic wait-free long-lived snapshot algorithm,
using only read and write operations, that guarantees polylogarithmic amortized
step complexity in all executions. This is the first non-blocking snapshot algorithm,
using reads and writes only, that has sub-linear amortized step complexity in
executions of arbitrary length. The key to our construction is a novel implementation
of a 2-component max array object which may be of independent interest.

text: In the superconducting regime of FeTe(1−x)Sex, there exist two types of vortices
which are distinguished by the presence or absence of zero-energy states in their
core. To understand their origin, we examine the interplay of Zeeman coupling
and superconducting pairings in three-dimensional metals with band inversion.
Weak Zeeman fields are found to suppress intraorbital spin-singlet pairing, known
to localize the states at the ends of the vortices on the surface. On the other
hand, an orbital-triplet pairing is shown to be stable against Zeeman interactions,
but leads to delocalized zero-energy Majorana modes which extend through the vortex.
In contrast, the finite-energy vortex modes remain localized at the vortex ends
even when the pairing is of orbital-triplet form. Phenomenologically, this manifests
as an observed disappearance of zero-bias peaks within the cores of topological
vortices upon an increase of the applied magnetic field. The presence of magnetic
impurities in FeTe(1−x)Sex, which are attracted to the vortices, would lead to
such Zeeman-induced delocalization of Majorana modes in a fraction of vortices
that capture a large enough number of magnetic impurities. Our results provide
an explanation for the dichotomy between topological and nontopological vortices
recently observed in FeTe(1−x)Sex.

text: We demonstrate that releasing atoms into free space from an optical lattice
does not deteriorate cavity-generated spin squeezing for metrological purposes.
In this work, an ensemble of 500000 spin-squeezed atoms in a high-finesse optical
cavity with near-uniform atom-cavity coupling is prepared, released into free
space, recaptured in the cavity, and probed. Up to ∼10 dB of metrologically relevant
squeezing is retrieved for 700μs free-fall times, and decaying levels of squeezing
are realized for up to 3 ms free-fall times. The degradation of squeezing results
from loss of atom-cavity coupling homogeneity between the initial squeezed state
generation and final collective state readout. A theoretical model is developed
to quantify this degradation and this model is experimentally validated.

text: Markov decision processes (MDPs) are the defacto framework for sequential
decision making in the presence of stochastic uncertainty. A classical optimization
criterion for MDPs is to maximize the expected discounted-sum payoff, which ignores
low probability catastrophic events with highly negative impact on the system.
On the other hand, risk-averse policies require the probability of undesirable
events to be below a given threshold, but they do not account for optimization
of the expected payoff. We consider MDPs with discounted-sum payoff with failure
states which represent catastrophic outcomes. The objective of risk-constrained
planning is to maximize the expected discounted-sum payoff among risk-averse policies
that ensure the probability to encounter a failure state is below a desired threshold.
Our main contribution is an efficient risk-constrained planning algorithm that
combines UCT-like search with a predictor learned through interaction with the
MDP (in the style of AlphaZero) and with a risk-constrained action selection via
linear programming. We demonstrate the effectiveness of our approach with experiments
on classical MDPs from the literature, including benchmarks with an order of 106
states.

text: Vaccinia virus–related kinase (VRK) is an evolutionarily conserved nuclear
protein kinase. VRK-1, the single Caenorhabditis elegans VRK ortholog, functions
in cell division and germline proliferation. However, the role of VRK-1 in postmitotic
cells and adult life span remains unknown. Here, we show that VRK-1 increases
organismal longevity by activating the cellular energy sensor, AMP-activated protein
kinase (AMPK), via direct phosphorylation. We found that overexpression of vrk-1
in the soma of adult C. elegans increased life span and, conversely, inhibition
of vrk-1 decreased life span. In addition, vrk-1 was required for longevity conferred
by mutations that inhibit C. elegans mitochondrial respiration, which requires
AMPK. VRK-1 directly phosphorylated and up-regulated AMPK in both C. elegans and
cultured human cells. Thus, our data show that the somatic nuclear kinase, VRK-1,
promotes longevity through AMPK activation, and this function appears to be conserved
between C. elegans and humans.

text: The actin cytoskeleton, a dynamic network of actin filaments and associated
F-actin–binding proteins, is fundamentally important in eukaryotes. α-Actinins
are major F-actin bundlers that are inhibited by Ca2+ in nonmuscle cells. Here
we report the mechanism of Ca2+-mediated regulation of Entamoeba histolytica α-actinin-2
(EhActn2) with features expected for the common ancestor of Entamoeba and higher
eukaryotic α-actinins. Crystal structures of Ca2+-free and Ca2+-bound EhActn2
reveal a calmodulin-like domain (CaMD) uniquely inserted within the rod domain.
Integrative studies reveal an exceptionally high affinity of the EhActn2 CaMD
for Ca2+, binding of which can only be regulated in the presence of physiological
concentrations of Mg2+. Ca2+ binding triggers an increase in protein multidomain
rigidity, reducing conformational flexibility of F-actin–binding domains via interdomain
cross-talk and consequently inhibiting F-actin bundling. In vivo studies uncover
that EhActn2 plays an important role in phagocytic cup formation and might constitute
a new drug target for amoebic dysentery.

text: We call a continuous self-map that reveals itself through a discrete set of
point-value pairs a sampled dynamical system. Capturing the available information
with chain maps on Delaunay complexes, we use persistent homology to quantify
the evidence of recurrent behavior. We establish a sampling theorem to recover
the eigenspaces of the endomorphism on homology induced by the self-map. Using
a combinatorial gradient flow arising from the discrete Morse theory for Čech
and Delaunay complexes, we construct a chain map to transform the problem from
the natural but expensive Čech complexes to the computationally efficient Delaunay
triangulations. The fast chain map algorithm has applications beyond dynamical
systems.

text: We consider the least singular value of a large random matrix with real or
complex i.i.d. Gaussian entries shifted by a constant z∈C. We prove an optimal
lower tail estimate on this singular value in the critical regime where z is around
the spectral edge, thus improving the classical bound of Sankar, Spielman and
Teng (SIAM J. Matrix Anal. Appl. 28:2 (2006), 446–476) for the particular shift-perturbation
in the edge regime. Lacking Brézin–Hikami formulas in the real case, we rely on
the superbosonization formula (Comm. Math. Phys. 283:2 (2008), 343–395).

text: We introduce a new graph problem, the token dropping game, and we show how
to solve it efficiently in a distributed setting. We use the token dropping game
as a tool to design an efficient distributed algorithm for the stable orientation
problem, which is a special case of the more general locally optimal semi-matching
problem. The prior work by Czygrinow et al. (DISC 2012) finds a locally optimal
semi-matching in O(Δ⁵) rounds in graphs of maximum degree Δ, which directly implies
an algorithm with the same runtime for stable orientations. We improve the runtime
to O(Δ⁴) for stable orientations and prove a lower bound of Ω(Δ) rounds.

text: "We consider the following dynamic load-balancing process: given an underlying
graph G with n nodes, in each step t≥ 0, one unit of load is created, and placed
at a randomly chosen graph node. In the same step, the chosen node picks a random
neighbor, and the two nodes balance their loads by averaging them. We are interested
in the expected gap between the minimum and maximum loads at nodes as the process
progresses, and its dependence on n and on the graph structure. Variants of the
above graphical balanced allocation process have been studied previously by Peres,
Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and
Sun, 2015]. These authors left as open the question of characterizing the gap
in the case of cycle graphs in the dynamic case, where weights are created during
the algorithm’s execution. For this case, the only known upper bound is of \U0001D4AA(n
log n), following from a majorization argument due to [Peres et al., 2015], which
analyzes a related graphical allocation process. In this paper, we provide an
upper bound of \U0001D4AA (√n log n) on the expected gap of the above process
for cycles of length n. We introduce a new potential analysis technique, which
enables us to bound the difference in load between k-hop neighbors on the cycle,
for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds
the maximum value of the gap by bounding its value across all possible subsets
of a certain structure, and recursively bounding the gaps within each subset.
We provide analytical and experimental evidence that our upper bound on the gap
is tight up to a logarithmic factor."

text: "Two plane drawings of geometric graphs on the same set of points are called
disjoint compatible if their union is plane and they do not have an edge in common.
For a given set S of 2n points two plane drawings of perfect matchings M1 and
M2 (which do not need to be disjoint nor compatible) are disjoint tree-compatible
if there exists a plane drawing of a spanning tree T on S which is disjoint compatible
to both M1 and M2.\r\nWe show that the graph of all disjoint tree-compatible perfect
geometric matchings on 2n points in convex position is connected if and only if
2n ≥ 10. Moreover, in that case the diameter\r\nof this graph is either 4 or 5,
independent of n."

text: "Fitting a function by using linear combinations of a large number N of `simple'
components is one of the most fruitful ideas in statistical learning. This idea
lies at the core of a variety of methods, from two-layer neural networks to kernel
regression, to boosting. In general, the resulting risk minimization problem is
non-convex and is solved by gradient descent or its variants. Unfortunately, little
is known about global convergence properties of these approaches.\r\nHere we consider
the problem of learning a concave function f on a compact convex domain Ω⊆ℝd,
using linear combinations of `bump-like' components (neurons). The parameters
to be fitted are the centers of N bumps, and the resulting empirical risk minimization
problem is highly non-convex. We prove that, in the limit in which the number
of neurons diverges, the evolution of gradient descent converges to a Wasserstein
gradient flow in the space of probability distributions over Ω. Further, when
the bump width δ tends to 0, this gradient flow has a limit which is a viscous
porous medium equation. Remarkably, the cost function optimized by this gradient
flow exhibits a special property known as displacement convexity, which implies
exponential convergence rates for N→∞, δ→0. Surprisingly, this asymptotic theory
appears to capture well the behavior for moderate values of δ,N. Explaining this
phenomenon, and understanding the dependence on δ,N in a quantitative manner remains
an outstanding challenge."

text: "In ecology, climate and other fields, (sub)systems have been identified that
can transition into a qualitatively different state when a critical threshold
or tipping point in a driving process is crossed. An understanding of those tipping
elements is of great interest given the increasing influence of humans on the
biophysical Earth system. Complex interactions exist between tipping elements,
e.g. physical mechanisms connect subsystems of the climate system. Based on earlier
work on such coupled nonlinear systems, we systematically assessed the qualitative
long-term behaviour of interacting tipping elements. We developed an understanding
of the consequences of interactions\r\non the tipping behaviour allowing for tipping
cascades to emerge under certain conditions. The (narrative) application of\r\nthese
qualitative results to real-world examples of interacting tipping elements indicates
that tipping cascades with profound consequences may occur: the interacting Greenland
ice sheet and thermohaline ocean circulation might tip before the tipping points
of the isolated subsystems are crossed. The eutrophication of the first lake in
a lake chain might propagate through the following lakes without a crossing of
their individual critical nutrient input levels. The possibility of emerging cascading
tipping dynamics calls for the development of a unified theory of interacting
tipping elements and the quantitative analysis of interacting real-world tipping
elements."

text: A working group, which was established within the Network of Repository Managers (RepManNet), has dealt with common certifications for repositories. In
addition, current requirements of the research funding agencies FWF and EU were
also taken into account. The Core Trust Seal was examined in more detail. For
this purpose, a questionnaire was sent to those organizations that are already certified
with CTS in Austria. The answers were summarized and evaluated anonymously. It
is recommended to go for a repository certification. Moreover, the development
of a DINI certificate in Austria is strongly suggested.

text: "A mesophilic methanogenic culture, designated JL01, was isolated from Holocene
permafrost in the Russian Arctic [1]. After long-term extensive cultivation at
15°C it turned out to be a tied binary culture of archaeal (JL01) and bacterial
(Sphaerochaeta associata GLS2) strains.\r\nStrain JL01 was a strict anaerobe and
grew on methanol, acetate and methylamines as energy and carbon sources. Cells
were irregular coccoid, non-motile, non-spore-forming, and Gram-stainpositive.
Optimum conditions for growth were 24-28 oC, pH 6.8–7.3 and 0.075-0.1 M NaCl.\r\nPhylogenetic
tree reconstructions based on 16S rRNA and concatenated alignment of broadly\r\nconserved
protein-coding genes revealed its close relation to Methanosarcina mazei S-6\r\nT
(similarity 99.5%). The comparison of whole genomic sequences (ANI) of the isolate
and the type strain of M.mazei was 98.5%, which is higher than the values recommended
for new species. Thus strain JL01 (=VKM B-2370=JCM 31898) represents the first
M. mazei isolated from permanently subzero Arcticsediments. The long-term co-cultivation
of JL01 with S. associata GLS2T showed the methane production without any additional
carbon and energy sources. Genome analysis of S. associata GLS2T revealed putative
genes involved in methanochondroithin catabolism."
