text: Hole gases in planar germanium can have high mobilities in combination with
strong spin-orbit interaction and electrically tunable g factors, and are therefore
emerging as a promising platform for creating hybrid superconductor-semiconductor
devices. A key challenge towards hybrid Ge-based quantum technologies is the design
of high-quality interfaces and superconducting contacts that are robust against
magnetic fields. In this work, by combining the assets of aluminum, which provides
good contact to the Ge, and niobium, which has a significant superconducting gap,
we demonstrate highly transparent low-disordered JoFETs with relatively large
ICRN products that are capable of withstanding high magnetic fields. We furthermore
demonstrate the ability of phase-biasing individual JoFETs, opening up an avenue
to explore topological superconductivity in planar Ge. The persistence of superconductivity
in the reported hybrid devices beyond 1.8 T paves the way towards integrating
spin qubits and proximity-induced superconductivity on the same chip.

text: While sexual reproduction is widespread among many taxa, asexual lineages
have repeatedly evolved from sexual ancestors. Despite extensive research on the
evolution of sex, it is still unclear whether this switch represents a major transition
requiring major molecular reorganization, and how convergent the changes involved
are. In this study, we investigated the phylogenetic relationship and patterns
of gene expression of sexual and asexual lineages of Eurasian Artemia brine shrimp,
to assess how gene expression patterns are affected by the transition to asexuality.
We find only a few genes that are consistently associated with the evolution of
asexuality, suggesting that this shift may not require an extensive overhauling
of the meiotic machinery. While genes with sex-biased expression have high rates
of expression divergence within Eurasian Artemia, neither female- nor male-biased
genes appear to show unusual evolutionary patterns after sexuality is lost, contrary
to theoretical expectations.

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 (GRNs) remains a major challenge. Here, we use a well-defined synthetic
GRN to study in Escherichia coli 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 GRN with fixed topology can display not only quantitatively
but also qualitatively different phenotypes, depending solely on the local genetic
context of its components. Transcriptional read-through is the main molecular
mechanism that places one transcriptional unit (TU) within two separate regulons
without the need for complex regulatory sequences. We propose that relative order
of individual TUs, with its potential for combinatorial complexity, plays an important
role in shaping phenotypes of GRNs.

text: "We introduce a novel technique to automatically decompose an input object’s
volume into a set of parts that can be represented by two opposite height fields.
Such decomposition enables the manufacturing of individual parts using two-piece
reusable rigid molds. Our decomposition strategy relies on a new energy formulation
that utilizes a pre-computed signal on the mesh volume representing the accessibility
for a predefined set of extraction directions. Thanks to this novel formulation,
our method allows for efficient optimization of a fabrication-aware partitioning
of volumes in a completely\r\nautomatic way. We demonstrate the efficacy of our
approach by generating valid volume partitionings for a wide range of complex
objects and physically reproducing several of them."

text: The Massively Parallel Computation (MPC) model is an emerging model that distills
core aspects of distributed and parallel computation, developed as a tool to solve
combinatorial (typically graph) problems in systems of many machines with limited
space. Recent 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 the fundamental problems of Maximal Matching and Maximal Independent
Set. However, there have been no prior corresponding deterministic algorithms.
A major challenge underlying the sublinear space setting is that the local space
of each machine might be too small to store all edges incident to a single node.
This poses a considerable obstacle compared to 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 the additional property that solving the
problem on this subgraph provides significant progress towards solving the problem
for the original input graph. Using this framework to derandomize the well-known
algorithm of Luby [SICOMP’86], we obtain O(log Δ + log log n)-round deterministic
MPC algorithms for solving the problems of Maximal Matching and Maximal Independent
Set with O(nɛ) space on each machine for any constant ɛ > 0. These algorithms
also run in O(log Δ) rounds in the closely related model of CONGESTED CLIQUE,
improving upon the state-of-the-art bound of O(log 2Δ) rounds by Censor-Hillel
et al. [DISC’17].

text: We investigate the effect of coupling between translational and internal degrees
of freedom of composite quantum particles on their localization in a random potential.
We show that entanglement between the two degrees of freedom weakens localization
due to the upper bound imposed on the inverse participation ratio by purity of
a quantum state. We perform numerical calculations for a two-particle system bound
by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered
lattice. We illustrate that the coupling has a dramatic effect on localization
properties, even with a small number of internal states participating in quantum
dynamics.

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 stable orientations
and more generally for locally optimal semi-matchings. The prior work by Czygrinow
et al. (DISC 2012) finds a stable orientation in O(Δ^5) rounds in graphs of maximum
degree Δ, while we improve it to O(Δ^4) and also prove a lower bound of Ω(Δ).
For the more general problem of locally optimal semi-matchings, the prior upper
bound is O(S^5) and our new algorithm runs in O(C · S^4) rounds, which is an improvement
for C = o(S); here C and S are the maximum degrees of customers and servers, respectively.

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: This thesis is the result of the research carried out by the author during
his PhD at IST Austria between 2017 and 2021. It mainly focuses on the Fröhlich
polaron model, specifically to its regime of strong coupling. This model, which
is rigorously introduced and discussed in the introduction, has been of great
interest in condensed matter physics and field theory for more than eighty years.
It is used to describe an electron interacting with the atoms of a solid material
(the strength of this interaction is modeled by the presence of a coupling constant
α in the Hamiltonian of the system). The particular regime examined here, which
is mathematically described by considering the limit α →∞, displays many interesting
features related to the emergence of classical behavior, which allows for a simplified
effective description of the system under analysis. The properties, the range
of validity and a quantitative analysis of the precision of such classical approximations
are the main object of the present work. We specify our investigation to the study
of the ground state energy of the system, its dynamics and its effective mass.
For each of these problems, we provide in the introduction an overview of the
previously known results and a detailed account of the original contributions
by the author.

text: As the size and complexity of models and datasets grow, so does the need for
communication-efficient variants of stochastic gradient descent that can be deployed
to perform parallel model training. One popular communication-compression method
for data-parallel SGD is QSGD (Alistarh et al., 2017), which quantizes and encodes
gradients to reduce communication costs. The baseline variant of QSGD provides
strong theoretical guarantees, however, for practical purposes, the authors proposed
a heuristic variant which we call QSGDinf, which demonstrated impressive empirical
gains for distributed training of large neural networks. In this paper, we build
on this work to propose a new gradient quantization scheme, and show that it has
both stronger theoretical guarantees than QSGD, and matches and exceeds the empirical
performance of the QSGDinf heuristic and of other compression methods.

text: The synaptotrophic hypothesis posits that synapse formation stabilizes dendritic
branches, yet this hypothesis has not been causally tested in vivo in the mammalian
brain. Presynaptic ligand cerebellin-1 (Cbln1) and postsynaptic receptor GluD2
mediate synaptogenesis between granule cells and Purkinje cells in the molecular
layer of the cerebellar cortex. Here we show that sparse but not global knockout
of GluD2 causes under-elaboration of Purkinje cell dendrites in the deep molecular
layer and overelaboration in the superficial molecular layer. Developmental, overexpression,
structure-function, and genetic epistasis analyses indicate that dendrite morphogenesis
defects result from competitive synaptogenesis in a Cbln1/GluD2-dependent manner.
A generative model of dendritic growth based on competitive synaptogenesis largely
recapitulates GluD2 sparse and global knockout phenotypes. Our results support
the synaptotrophic hypothesis at initial stages of dendrite development, suggest
a second mode in which cumulative synapse formation inhibits further dendrite
growth, and highlight the importance of competition in dendrite morphogenesis.

text: We provide a definition of the effective mass for the classical polaron described
by the Landau-Pekar equations. It is based on a novel variational principle, minimizing
the energy functional over states with given (initial) velocity. The resulting
formula for the polaron's effective mass agrees with the prediction by Landau
and Pekar.

text: Normative theories and statistical inference provide complementary approaches
for the study of biological systems. A normative theory postulates that organisms
have adapted to efficiently solve essential tasks, and proceeds to mathematically
work out testable consequences of such optimality; parameters that maximize the
hypothesized organismal function can be derived ab initio, without reference to
experimental data. In contrast, statistical inference focuses on efficient utilization
of data to learn model parameters, without reference to any a priori notion of
biological function, utility, or fitness. Traditionally, these two approaches
were developed independently and applied separately. Here we unify them in a coherent
Bayesian framework that embeds a normative theory into a family of maximum-entropy
“optimization priors.” This family defines a smooth interpolation between a data-rich
inference regime (characteristic of “bottom-up” statistical models), and a data-limited
ab inito prediction regime (characteristic of “top-down” normative theory). We
demonstrate the applicability of our framework using data from the visual cortex,
and argue that the flexibility it affords is essential to address a number of
fundamental challenges relating to inference and prediction in complex, high-dimensional
biological problems.

text: ' We consider the problem of estimating a signal from measurements obtained
via a generalized linear model. We focus on estimators based on approximate message
passing (AMP), a family of iterative algorithms with many appealing features:
the performance of AMP in the high-dimensional limit can be succinctly characterized
under suitable model assumptions; AMP can also be tailored to the empirical distribution
of the signal entries, and for a wide class of estimation problems, AMP is conjectured
to be optimal among all polynomial-time algorithms. However, a major issue of
AMP is that in many models (such as phase retrieval), it requires an initialization
correlated with the ground-truth signal and independent from the measurement matrix.
Assuming that such an initialization is available is typically not realistic.
In this paper, we solve this problem by proposing an AMP algorithm initialized
with a spectral estimator. With such an initialization, the standard AMP analysis
fails since the spectral estimator depends in a complicated way on the design
matrix. Our main contribution is a rigorous characterization of the performance
of AMP with spectral initialization in the high-dimensional limit. The key technical
idea is to define and analyze a two-phase artificial AMP algorithm that first
produces the spectral estimator, and then closely approximates the iterates of
the true AMP. We also provide numerical results that demonstrate the validity
of the proposed approach. '

text: This paper aims to obtain a strong convergence result for a Douglas–Rachford
splitting method with inertial extrapolation step for finding a zero of the sum
of two set-valued maximal monotone operators without any further assumption of
uniform monotonicity on any of the involved maximal monotone operators. Furthermore,
our proposed method is easy to implement and the inertial factor in our proposed
method is a natural choice. Our method of proof is of independent interest. Finally,
some numerical implementations are given to confirm the theoretical analysis.

text: "In the worldwide endeavor for disruptive quantum technologies, germanium
is emerging as a versatile material to realize devices capable of encoding, processing,
or transmitting quantum information. These devices leverage special properties
of the germanium valence-band states, commonly known as holes, such as their inherently
strong spin-orbit coupling and the ability to host superconducting pairing correlations.
In this Review, we initially introduce the physics of holes in low-dimensional
germanium structures with key insights from a theoretical perspective. We then
examine the material science progress underpinning germanium-based planar heterostructures
and nanowires. We review the most significant experimental results demonstrating
key building blocks for quantum technology, such as an electrically driven universal
quantum gate set with spin qubits in quantum dots and superconductor-semiconductor
devices for hybrid quantum systems. We conclude by identifying the most promising
prospects\r\ntoward scalable quantum information processing. "
