text: "We study the problem of recovering an unknown signal \U0001D465\U0001D465
given measurements obtained from a generalized linear model with a Gaussian sensing
matrix. Two popular solutions are based on a linear estimator \U0001D465\U0001D465^L
and a spectral estimator \U0001D465\U0001D465^s. The former is a data-dependent
linear combination of the columns of the measurement matrix, and its analysis
is quite simple. The latter is the principal eigenvector of a data-dependent matrix,
and a recent line of work has studied its performance. In this paper, we show
how to optimally combine \U0001D465\U0001D465^L and \U0001D465\U0001D465^s. At
the heart of our analysis is the exact characterization of the empirical joint
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s)
in the high-dimensional limit. This allows us to compute the Bayes-optimal combination
of \U0001D465\U0001D465^L and \U0001D465\U0001D465^s, given the limiting distribution
of the signal \U0001D465\U0001D465. When the distribution of the signal is Gaussian,
then the Bayes-optimal combination has the form \U0001D703\U0001D465\U0001D465^L+\U0001D465\U0001D465^s
and we derive the optimal combination coefficient. In order to establish the limiting
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s),
we design and analyze an approximate message passing algorithm whose iterates
give \U0001D465\U0001D465^L and approach \U0001D465\U0001D465^s. Numerical simulations
demonstrate the improvement of the proposed combination with respect to the two
methods considered separately."

text: This paper gives tight logarithmic lower bounds on the solo step complexity
of leader election in an asynchronous shared-memory model with single-writer multi-reader
(SWMR) registers, for both deterministic and randomized obstruction-free algorithms.
The approach extends to lower bounds for deterministic and randomized obstruction-free
algorithms using multi-writer registers under bounded write concurrency, showing
a trade-off between the solo step complexity of a leader election algorithm, and
the worst-case number of stalls incurred by a processor in an execution.

text: 'Let G be a graph on n nodes. In the stochastic population protocol model,
a collection of n indistinguishable, resource-limited nodes collectively solve
tasks via pairwise interactions. In each interaction, two randomly chosen neighbors
first read each other’s states, and then update their local states. A rich line
of research has established tight upper and lower bounds on the complexity of
fundamental tasks, such as majority and leader election, in this model, when G
is a clique. Specifically, in the clique, these tasks can be solved fast, i.e.,
in n polylog n pairwise interactions, with high probability, using at most polylog
n states per node. In this work, we consider the more general setting where G
is an arbitrary graph, and present a technique for simulating protocols designed
for fully-connected networks in any connected regular graph. Our main result is
a simulation that is efficient on many interesting graph families: roughly, the
simulation overhead is polylogarithmic in the number of nodes, and quadratic in
the conductance of the graph. As an example, this implies that, in any regular
graph with conductance φ, both leader election and exact majority can be solved
in φ^{-2} ⋅ n polylog n pairwise interactions, with high probability, using at
most φ^{-2} ⋅ polylog n states per node. This shows that there are fast and space-efficient
population protocols for leader election and exact majority on graphs with good
expansion properties.'

text: We show that any algorithm that solves the sinkless orientation problem in
the supported LOCAL model requires Ω(log n) rounds, and this is tight. The supported
LOCAL is at least as strong as the usual LOCAL model, and as a corollary this
also gives a new, short and elementary proof that shows that the round complexity
of the sinkless orientation problem in the deterministic LOCAL model is Ω(log
n).

text: "We study conditions under which a finite simplicial complex K can be mapped
to ℝd without higher-multiplicity intersections. An almost r-embedding is a map
f: K → ℝd such that the images of any r pairwise disjoint simplices of K do not
have a common point. We show that if r is not a prime power and d ≥ 2r + 1, then
there is a counterexample to the topological Tverberg conjecture, i.e., there
is an almost r-embedding of the (d +1)(r − 1)-simplex in ℝd. This improves on
previous constructions of counterexamples (for d ≥ 3r) based on a series of papers
by M. Özaydin, M. Gromov, P. Blagojević, F. Frick, G. Ziegler, and the second
and fourth present authors.\r\n\r\nThe counterexamples are obtained by proving
the following algebraic criterion in codimension 2: If r ≥ 3 and if K is a finite
2(r − 1)-complex, then there exists an almost r-embedding K → ℝ2r if and only
if there exists a general position PL map f: K → ℝ2r such that the algebraic intersection
number of the f-images of any r pairwise disjoint simplices of K is zero. This
result can be restated in terms of a cohomological obstruction and extends an
analogous codimension 3 criterion by the second and fourth authors. As another
application, we classify ornaments f: S3 ⊔ S3 ⊔ S3 → ℝ5 up to ornament concordance.\r\n\r\nIt
follows from work of M. Freedman, V. Krushkal and P. Teichner that the analogous
criterion for r = 2 is false. We prove a lemma on singular higher-dimensional
Borromean rings, yielding an elementary proof of the counterexample."

text: We prove that any deterministic matrix is approximately the identity in the
eigenbasis of a large random Wigner matrix with very high probability and with
an optimal error inversely proportional to the square root of the dimension. Our
theorem thus rigorously verifies the Eigenstate Thermalisation Hypothesis by Deutsch
(Phys Rev A 43:2046–2049, 1991) for the simplest chaotic quantum system, the Wigner
ensemble. In mathematical terms, we prove the strong form of Quantum Unique Ergodicity
(QUE) with an optimal convergence rate for all eigenvectors simultaneously, generalizing
previous probabilistic QUE results in Bourgade and Yau (Commun Math Phys 350:231–278,
2017) and Bourgade et al. (Commun Pure Appl Math 73:1526–1596, 2020).

text: Consider a random set of points on the unit sphere in ℝd, which can be either
uniformly sampled or a Poisson point process. Its convex hull is a random inscribed
polytope, whose boundary approximates the sphere. We focus on the case d = 3,
for which there are elementary proofs and fascinating formulas for metric properties.
In particular, we study the fraction of acute facets, the expected intrinsic volumes,
the total edge length, and the distance to a fixed point. Finally we generalize
the results to the ellipsoid with homeoid density.

text: Growth regulation tailors development in plants to their environment. A prominent
example of this is the response to gravity, in which shoots bend up and roots
bend down1. This paradox is based on opposite effects of the phytohormone auxin,
which promotes cell expansion in shoots while inhibiting it in roots via a yet
unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic
engineering and phosphoproteomics in Arabidopsis thaliana, we advance understanding
of how auxin inhibits root growth. We show that auxin activates two distinct,
antagonistically acting signalling pathways that converge on rapid regulation
of apoplastic pH, a causative determinant of growth. Cell surface-based TRANSMEMBRANE
KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma
membrane H+-ATPases for apoplast acidification, while intracellular canonical
auxin signalling promotes net cellular H+ influx, causing apoplast alkalinization.
Simultaneous activation of these two counteracting mechanisms poises roots for
rapid, fine-tuned growth modulation in navigating complex soil environments.

text: We investigate the Fröhlich polaron model on a three-dimensional torus, and
give a proof of the second-order quantum corrections to its ground-state energy
in the strong-coupling limit. Compared to previous work in the confined case,
the translational symmetry (and its breaking in the Pekar approximation) makes
the analysis substantially more challenging.

text: Tropisms are among the most important growth responses for plant adaptation
to the surrounding environment. One of the most common tropisms is root gravitropism.
Root gravitropism enables the plant to anchor securely to the soil enabling the
absorption of water and nutrients. Most of the knowledge related to the plant
gravitropism has been acquired from the flowering plants, due to limited research
in non-seed plants. Limited research on non-seed plants is due in large part to
the lack of standard research methods. Here, we describe the experimental methods
to evaluate gravitropism in representative non-seed plant species, including the
non-vascular plant moss Physcomitrium patens, the early diverging extant vascular
plant lycophyte Selaginella moellendorffii and fern Ceratopteris richardii. In
addition, we introduce the methods used for statistical analysis of the root gravitropism
in non-seed plant species.
acknowledgement: The Ceratopteris richardii spores were obtained from the lab of Jo
Ann Banks at Purdue University. This work was supported by funding from the European
Union’s Horizon 2020 research and innovation program (ERC grant agreement number

text: The analysis of dynamic cellular processes such as plant cytokinesis stands
and falls with live-cell time-lapse confocal imaging. Conventional approaches
to time-lapse imaging of cell division in Arabidopsis root tips are tedious and
have low throughput. Here, we describe a protocol for long-term time-lapse simultaneous
imaging of multiple root tips on a vertical-stage confocal microscope with automated
root tracking. We also provide modifications of the basic protocol to implement
this imaging method in the analysis of genetic, pharmacological or laser ablation
wounding-mediated experimental manipulations. Our method dramatically improves
the efficiency of cell division time-lapse imaging by increasing the throughput,
while reducing the person-hour requirements of such experiments.

text: Plants develop new organs to adjust their bodies to dynamic changes in the
environment. How independent organs achieve anisotropic shapes and polarities
is poorly understood. To address this question, we constructed a mechano-biochemical
model for Arabidopsis root meristem growth that integrates biologically plausible
principles. Computer model simulations demonstrate how differential growth of
neighboring tissues results in the initial symmetry-breaking leading to anisotropic
root growth. Furthermore, the root growth feeds back on a polar transport network
of the growth regulator auxin. Model, predictions are in close agreement with
in vivo patterns of anisotropic growth, auxin distribution, and cell polarity,
as well as several root phenotypes caused by chemical, mechanical, or genetic
perturbations. Our study demonstrates that the combination of tissue mechanics
and polar auxin transport organizes anisotropic root growth and cell polarities
during organ outgrowth. Therefore, a mobile auxin signal transported through immobile
cells drives polarity and growth mechanics to coordinate complex organ development.

text: 'Machines enabled the Industrial Revolution and are central to modern technological
progress: A machine’s parts transmit forces, motion, and energy to one another
in a predetermined manner. Today’s engineering frontier, building artificial micromachines
that emulate the biological machinery of living organisms, requires faithful assembly
and energy consumption at the microscale. Here, we demonstrate the programmable
assembly of active particles into autonomous metamachines using optical templates.
Metamachines, or machines made of machines, are stable, mobile and autonomous
architectures, whose dynamics stems from the geometry. We use the interplay between
anisotropic force generation of the active colloids with the control of their
orientation by local geometry. This allows autonomous reprogramming of active
particles of the metamachines to achieve multiple functions. It permits the modular
assembly of metamachines by fusion, reconfiguration of metamachines and, we anticipate,
a shift in focus of self-assembly towards active matter and reprogrammable materials.'

text: Mutations affecting mTOR or RAS signaling underlie defined syndromes (the
so-called mTORopathies and RASopathies) with high risk for Autism Spectrum Disorder
(ASD). These syndromes show a broad variety of somatic phenotypes including cancers,
skin abnormalities, heart disease and facial dysmorphisms. Less well studied are
the neuropsychiatric symptoms such as ASD. Here, we assess the relevance of these
signalopathies in ASD reviewing genetic, human cell model, rodent studies and
clinical trials. We conclude that signalopathies have an increased liability for
ASD and that, in particular, ASD individuals with dysmorphic features and intellectual
disability (ID) have a higher chance for disruptive mutations in RAS- and mTOR-related
genes. Studies on rodent and human cell models confirm aberrant neuronal development
as the underlying pathology. Human studies further suggest that multiple hits
are necessary to induce the respective phenotypes. Recent clinical trials do only
report improvements for comorbid conditions such as epilepsy or cancer but not
for behavioral aspects. Animal models show that treatment during early development
can rescue behavioral phenotypes. Taken together, we suggest investigating the
differential roles of mTOR and RAS signaling in both human and rodent models,
and to test drug treatment both during and after neuronal development in the available
model systems

text: Advanced transcriptome sequencing has revealed that the majority of eukaryotic
genes undergo alternative splicing (AS). Nonetheless, little effort has been dedicated
to investigating the functional relevance of particular splicing events, even
those in the key developmental and hormonal regulators. Combining approaches of
genetics, biochemistry and advanced confocal microscopy, we describe the impact
of alternative splicing on the PIN7 gene in the model plant Arabidopsis thaliana.
PIN7 encodes a polarly localized transporter for the phytohormone auxin and produces
two evolutionarily conserved transcripts, PIN7a and PIN7b. PIN7a and PIN7b, differing
in a four amino acid stretch, exhibit almost identical expression patterns and
subcellular localization. We reveal that they are closely associated and mutually
influence each other's mobility within the plasma membrane. Phenotypic complementation
tests indicate that the functional contribution of PIN7b per se is minor, but
it markedly reduces the prominent PIN7a activity, which is required for correct
seedling apical hook formation and auxin-mediated tropic responses. Our results
establish alternative splicing of the PIN family as a conserved, functionally
relevant mechanism, revealing an additional regulatory level of auxin-mediated
plant development.

text: 'During the past decade, the scientific community and outside observers have
noted a concerning lack of rigor and transparency in preclinical research that
led to talk of a “reproducibility crisis” in the life sciences (Baker, 2016; Bespalov
& Steckler, 2018; Heddleston et al, 2021). Various measures have been proposed
to address the problem: from better training of scientists to more oversight to
expanded publishing practices such as preregistration of studies. The recently
published EQIPD (Enhancing Quality in Preclinical Data) System is, to date, the
largest initiative that aims to establish a systematic approach for increasing
the robustness and reliability of biomedical research (Bespalov et al, 2021).
However, promoting a cultural change in research practices warrants a broad adoption
of the Quality System and its underlying philosophy. It is here that academic
Core Facilities (CF), research service providers at universities and research
institutions, can make a difference. It is fair to assume that a significant fraction
of published data originated from experiments that were designed, run, or analyzed
in CFs. These academic services play an important role in the research ecosystem
by offering access to cutting-edge equipment and by developing and testing novel
techniques and methods that impact research in the academic and private sectors
alike (Bikovski et al, 2020). Equipment and infrastructure are not the only value:
CFs employ competent personnel with profound knowledge and practical experience
of the specific field of interest: animal behavior, imaging, crystallography,
genomics, and so on. Thus, CFs are optimally positioned to address concerns about
the quality and robustness of preclinical research.'

text: We study the overlaps between right and left eigenvectors for random matrices
of the spherical ensemble, as well as truncated unitary ensembles in the regime
where half of the matrix at least is truncated. These two integrable models exhibit
a form of duality, and the essential steps of our investigation can therefore
be performed in parallel. In every case, conditionally on all eigenvalues, diagonal
overlaps are shown to be distributed as a product of independent random variables
with explicit distributions. This enables us to prove that the scaled diagonal
overlaps, conditionally on one eigenvalue, converge in distribution to a heavy-tail
limit, namely, the inverse of a γ2 distribution. We also provide formulae for
the conditional expectation of diagonal and off-diagonal overlaps, either with
respect to one eigenvalue, or with respect to the whole spectrum. These results,
analogous to what is known for the complex Ginibre ensemble, can be obtained in
these cases thanks to integration techniques inspired from a previous work by
Forrester & Krishnapur.

text: A precise quantitative description of the ultrastructural characteristics
underlying biological mechanisms is often key to their understanding. This is
particularly true for dynamic extra- and intracellular filamentous assemblies,
playing a role in cell motility, cell integrity, cytokinesis, tissue formation
and maintenance. For example, genetic manipulation or modulation of actin regulatory
proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural
architecture of actin filament-rich cell peripheral structures, such as lamellipodia
or filopodia. However, the observed ultrastructural effects often remain subtle
and require sufficiently large datasets for appropriate quantitative analysis.
The acquisition of such large datasets has been enabled by recent advances in
high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates
the development of complementary approaches to maximize the extraction of relevant
biological information. We have developed a computational toolbox for the semi-automatic
quantification of segmented and vectorized filamentous networks from pre-processed
cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple
experimental conditions. GUI-based components simplify the processing of data
and allow users to obtain a large number of ultrastructural parameters describing
filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing
cryo-ET data of untreated and chemically perturbed branched actin filament networks
and that of parallel actin filament arrays. In principle, the computational toolbox
presented here is applicable for data analysis comprising any type of filaments
in regular (i.e. parallel) or random arrangement. We show that it can ease the
identification of key differences between experimental groups and facilitate the
in-depth analysis of ultrastructural data in a time-efficient manner.

text: "Indirect reciprocity in evolutionary game theory is a prominent mechanism
for explaining the evolution of cooperation among unrelated individuals. In contrast
to direct reciprocity, which is based on individuals meeting repeatedly, and conditionally
cooperating by using their own experiences, indirect reciprocity is based on individuals’
reputations. If a player helps another, this increases the helper’s public standing,
benefitting them in the future. This lets cooperation in the population emerge
without individuals having to meet more than once. While the two modes of reciprocity
are intertwined, they are difficult to compare. Thus, they are usually studied
in isolation. Direct reciprocity can maintain cooperation with simple strategies,
and is robust against noise even when players do not remember more\r\nthan their
partner’s last action. Meanwhile, indirect reciprocity requires its successful
strategies, or social norms, to be more complex. Exhaustive search previously
identified eight such norms, called the “leading eight”, which excel at maintaining
cooperation. However, as the first result of this thesis, we show that the leading
eight break down once we remove the fundamental assumption that information is
synchronized and public, such that everyone agrees on reputations. Once we consider
a more realistic scenario of imperfect information, where reputations are private,
and individuals occasionally misinterpret or miss observations, the leading eight
do not promote cooperation anymore. Instead, minor initial disagreements can proliferate,
fragmenting populations into subgroups. In a next step, we consider ways to mitigate
this issue. We first explore whether introducing “generosity” can stabilize cooperation
when players use the leading eight strategies in noisy environments. This approach
of modifying strategies to include probabilistic elements for coping with errors
is known to work well in direct reciprocity. However, as we show here, it fails
for the more complex norms of indirect reciprocity. Imperfect information still
prevents cooperation from evolving. On the other hand, we succeeded to show in
this thesis that modifying the leading eight to use “quantitative assessment”,
i.e. tracking reputation scores on a scale beyond good and bad, and making overall
judgments of others based on a threshold, is highly successful, even when noise
increases in the environment. Cooperation can flourish when reputations\r\nare
more nuanced, and players have a broader understanding what it means to be “good.”
Finally, we present a single theoretical framework that unites the two modes of
reciprocity despite their differences. Within this framework, we identify a novel
simple and successful strategy for indirect reciprocity, which can cope with noisy
environments and has an analogue in direct reciprocity. We can also analyze decision
making when different sources of information are available. Our results help highlight
that for sustaining cooperation, already the most simple rules of reciprocity
can be sufficient."
