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."

text: Turbulence generally arises in shear flows if velocities and hence, inertial
forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit
disordered motion even at vanishing inertia. Intermediate between these cases,
a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed
in a narrow Reynolds number interval. We here determine the origin of EIT in experiments
and show that characteristic EIT structures can be detected across an unexpectedly
wide range of parameters. Close to onset, a pattern of chevron-shaped streaks
emerges in qualitative agreement with linear and weakly nonlinear theory. However,
in experiments, the dynamics remain weakly chaotic, and the instability can be
traced to far lower Reynolds numbers than permitted by theory. For increasing
inertia, the flow undergoes a transformation to a wall mode composed of inclined
near-wall streaks and shear layers. This mode persists to what is known as the
“maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic
flows across more than three orders of magnitude in Reynolds number.

text: De novo protein synthesis is required for synapse modifications underlying
stable memory encoding. Yet neurons are highly compartmentalized cells and how
protein synthesis can be regulated at the synapse level is unknown. Here, we characterize
neuronal signaling complexes formed by the postsynaptic scaffold GIT1, the mechanistic
target of rapamycin (mTOR) kinase, and Raptor that couple synaptic stimuli to
mTOR-dependent protein synthesis; and identify NMDA receptors containing GluN3A
subunits as key negative regulators of GIT1 binding to mTOR. Disruption of GIT1/mTOR
complexes by enhancing GluN3A expression or silencing GIT1 inhibits synaptic mTOR
activation and restricts the mTOR-dependent translation of specific activity-regulated
mRNAs. Conversely, GluN3A removal enables complex formation, potentiates mTOR-dependent
protein synthesis, and facilitates the consolidation of associative and spatial
memories in mice. The memory enhancement becomes evident with light or spaced
training, can be achieved by selectively deleting GluN3A from excitatory neurons
during adulthood, and does not compromise other aspects of cognition such as memory
flexibility or extinction. Our findings provide mechanistic insight into synaptic
translational control and reveal a potentially selective target for cognitive
enhancement.

text: 'Nitrogen is an essential macronutrient determining plant growth, development
and affecting agricultural productivity. Root, as a hub that perceives and integrates
local and systemic signals on the plant’s external and endogenous nitrogen resources,
communicates with other plant organs to consolidate their physiology and development
in accordance with actual nitrogen balance. Over the last years, numerous studies
demonstrated that these comprehensive developmental adaptations rely on the interaction
between pathways controlling nitrogen homeostasis and hormonal networks acting
globally in the plant body. However, molecular insights into how the information
about the nitrogen status is translated through hormonal pathways into specific
developmental output are lacking. In my work, I addressed so far poorly understood
mechanisms underlying root-to-shoot communication that lead to a rapid re-adjustment
of shoot growth and development after nitrate provision. Applying a combination
of molecular, cell, and developmental biology approaches, genetics and grafting
experiments as well as hormonal analytics, I identified and characterized an unknown
molecular framework orchestrating shoot development with a root nitrate sensory
system. '

text: Bacteria-host interactions represent a continuous trade-off between benefit
and risk. Thus, the host immune response is faced with a non-trivial problem –
accommodate beneficial commensals and remove harmful pathogens. This is especially
difficult as molecular patterns, such as lipopolysaccharide or specific surface
organelles such as pili, are conserved in both, commensal and pathogenic bacteria.
Type 1 pili, tightly regulated by phase variation, are considered an important
virulence factor of pathogenic bacteria as they facilitate invasion into host
cells. While invasion represents a de facto passive mechanism for pathogens to
escape the host immune response, we demonstrate a fundamental role of type 1 pili
as active modulators of the innate and adaptive immune response.

text: A high-resolution structure of trimeric cyanobacterial Photosystem I (PSI)
from Thermosynechococcus elongatus was reported as the first atomic model of PSI
almost 20 years ago. However, the monomeric PSI structure has not yet been reported
despite long-standing interest in its structure and extensive spectroscopic characterization
of the loss of red chlorophylls upon monomerization. Here, we describe the structure
of monomeric PSI from Thermosynechococcus elongatus BP-1. Comparison with the
trimer structure gave detailed insights into monomerization-induced changes in
both the central trimerization domain and the peripheral regions of the complex.
Monomerization-induced loss of red chlorophylls is assigned to a cluster of chlorophylls
adjacent to PsaX. Based on our findings, we propose a role of PsaX in the stabilization
of red chlorophylls and that lipids of the surrounding membrane present a major
source of thermal energy for uphill excitation energy transfer from red chlorophylls
to P700.

text: A key attribute of persistent or recurring bacterial infections is the ability
of the pathogen to evade the host’s immune response. Many Enterobacteriaceae express
type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and
establish persistent infections. However, the molecular mechanisms and strategies
by which bacteria actively circumvent the immune response of the host remain poorly
understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide
detection, on dendritic cells as a previously undescribed binding partner of FimH,
the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH
amino acids involved in CD14 binding are highly conserved across pathogenic and
non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced
dendritic cell migration and blunted expression of co-stimulatory molecules, both
rate-limiting factors of T cell activation. While defining an active molecular
mechanism of immune evasion by pathogens, the interaction between FimH and CD14
represents a potential target to interfere with persistent and recurrent infections,
such as urinary tract infections or Crohn’s disease.

text: To survive elevated temperatures, ectotherms adjust the fluidity of membranes
by fine-tuning lipid desaturation levels in a process previously described to
be cell autonomous. We have discovered that, in Caenorhabditis elegans, neuronal
heat shock factor 1 (HSF-1), the conserved master regulator of the heat shock
response (HSR), causes extensive fat remodeling in peripheral tissues. These changes
include a decrease in fat desaturase and acid lipase expression in the intestine
and a global shift in the saturation levels of plasma membrane’s phospholipids.
The observed remodeling of plasma membrane is in line with ectothermic adaptive
responses and gives worms a cumulative advantage to warm temperatures. We have
determined that at least 6 TAX-2/TAX-4 cyclic guanosine monophosphate (cGMP) gated
channel expressing sensory neurons, and transforming growth factor ß (TGF-β)/bone
morphogenetic protein (BMP) are required for signaling across tissues to modulate
fat desaturation. We also find neuronal hsf-1 is not only sufficient but also
partially necessary to control the fat remodeling response and for survival at
warm temperatures. This is the first study to show that a thermostat-based mechanism
can cell nonautonomously coordinate membrane saturation and composition across
tissues in a multicellular animal.

text: Molecular chaperones are central to cellular protein homeostasis. Dynamic
disorder is a key feature of the complexes of molecular chaperones and their client
proteins, and it facilitates the client release towards a folded state or the
handover to downstream components. The dynamic nature also implies that a given
chaperone can interact with many different client proteins, based on physico-chemical
sequence properties rather than on structural complementarity of their (folded)
3D structure. Yet, the balance between this promiscuity and some degree of client
specificity is poorly understood. Here, we review recent atomic-level descriptions
of chaperones with client proteins, including chaperones in complex with intrinsically
disordered proteins, with membrane-protein precursors, or partially folded client
proteins. We focus hereby on chaperone-client interactions that are independent
of ATP. The picture emerging from these studies highlights the importance of dynamics
in these complexes, whereby several interaction types, not only hydrophobic ones,
contribute to the complex formation. We discuss these features of chaperone-client
complexes and possible factors that may contribute to this balance of promiscuity
and specificity.

text: Off-chain protocols (channels) are a promising solution to the scalability
and privacy challenges of blockchain payments. Current proposals, however, require
synchrony assumptions to preserve the safety of a channel, leaking to an adversary
the exact amount of time needed to control the network for a successful attack.
In this paper, we introduce Brick, the first payment channel that remains secure
under network asynchrony and concurrently provides correct incentives. The core
idea is to incorporate the conflict resolution process within the channel by introducing
a rational committee of external parties, called wardens. Hence, if a party wants
to close a channel unilaterally, it can only get the committee’s approval for
the last valid state. Additionally, Brick provides sub-second latency because
it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast
to announce updates and close the channel, a light-weight abstraction that is
powerful enough to preserve safety and liveness to any rational parties. We formally
define and prove for Brick the properties a payment channel construction should
fulfill. We also design incentives for Brick such that honest and rational behavior
aligns. Finally, we provide a reference implementation of the smart contracts
in Solidity.

text: Since the inception of Bitcoin, a plethora of distributed ledgers differing
in design and purpose has been created. While by design, blockchains provide no
means to securely communicate with external systems, numerous attempts towards
trustless cross-chain communication have been proposed over the years. Today,
cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges,
scalability efforts via sharding, extension of existing systems through sidechains,
and bootstrapping of new blockchains. Unfortunately, existing proposals are designed
ad-hoc for specific use-cases, making it hard to gain confidence in their correctness
and composability. We provide the first systematic exposition of cross-chain communication
protocols. We formalize the underlying research problem and show that CCC is impossible
without a trusted third party, contrary to common beliefs in the blockchain community.
With this result in mind, we develop a framework to design new and evaluate existing
CCC protocols, focusing on the inherent trust assumptions thereof, and derive
a classification covering the field of cross-chain communication to date. We conclude
by discussing open challenges for CCC research and the implications of interoperability
on the security and privacy of blockchains.

text: Strigolactones (SLs) are carotenoid-derived plant hormones that control shoot
branching and communications between host plants and symbiotic fungi or root parasitic
plants. Extensive studies have identified the key components participating in
SL biosynthesis and signalling, whereas the catabolism or deactivation of endogenous
SLs in planta remains largely unknown. Here, we report that the Arabidopsis carboxylesterase
15 (AtCXE15) and its orthologues function as efficient hydrolases of SLs. We show
that overexpression of AtCXE15 promotes shoot branching by dampening SL-inhibited
axillary bud outgrowth. We further demonstrate that AtCXE15 could bind and efficiently
hydrolyse SLs both in vitro and in planta. We also provide evidence that AtCXE15
is capable of catalysing hydrolysis of diverse SL analogues and that such CXE15-dependent
catabolism of SLs is evolutionarily conserved in seed plants. These results disclose
a catalytic mechanism underlying homoeostatic regulation of SLs in plants, which
also provides a rational approach to spatial-temporally manipulate the endogenous
SLs and thus architecture of crops and ornamental plants.

text: Composite materials offer numerous advantages in a wide range of applications,
including thermoelectrics. Here, semiconductor–metal composites are produced by
just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
and at room temperature with a metallic Cu powder. The obtained blend is annealed
in a reducing atmosphere and afterward consolidated into dense polycrystalline
pellets through spark plasma sintering (SPS). We observe that, during the annealing
process, the presence of metallic copper activates a partial reduction of the
PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
lead during the SPS process habilitates the liquid-phase sintering of the composite.
Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
that the presence of metallic lead decisively contributes to a strong increase
of the charge carrier concentration through spillover of charge carriers enabled
by the low work function of lead. The increase in charge carrier concentration
translates into much higher electrical conductivities and moderately lower Seebeck
coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
the presence of multiple phases in the final composite results in a notable decrease
in the lattice thermal conductivity. Overall, the introduction of metallic copper
in the initial blend results in a significant improvement of the thermoelectric
performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
= 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.

text: Erythropoietin enhances oxygen delivery and reduces hypoxia-induced cell death,
but its pro-thrombotic activity is problematic for use of erythropoietin in treating
hypoxia. We constructed a fusion protein that stimulates red blood cell production
and neuroprotection without triggering platelet production, a marker for thrombosis.
The protein consists of an anti-glycophorin A nanobody and an erythropoietin mutant
(L108A). The mutation reduces activation of erythropoietin receptor homodimers
that induce erythropoiesis and thrombosis, but maintains the tissue-protective
signaling. The binding of the nanobody element to glycophorin A rescues homodimeric
erythropoietin receptor activation on red blood cell precursors. In a cell proliferation
assay, the fusion protein is active at 10−14 M, allowing an estimate of the number
of receptor–ligand complexes needed for signaling. This fusion protein stimulates
erythroid cell proliferation in vitro and in mice, and shows neuroprotective activity
in vitro. Our erythropoietin fusion protein presents a novel molecule for treating
hypoxia.

text: The early development of many organisms involves the folding of cell monolayers,
but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic
causes and effects of local curvature remain unclear. Here we study epithelial
cell monolayers on corrugated hydrogels engineered into wavy patterns, examining
how concave and convex curvatures affect cellular and nuclear shape. We find that
substrate curvature affects monolayer thickness, which is larger in valleys than
crests. We show that this feature generically arises in a vertex model, leading
to the hypothesis that cells may sense curvature by modifying the thickness of
the tissue. We find that local curvature also affects nuclear morphology and positioning,
which we explain by extending the vertex model to take into account membrane–nucleus
interactions, encoding thickness modulation in changes to nuclear deformation
and position. We propose that curvature governs the spatial distribution of yes-associated
proteins via nuclear shape and density changes. We show that curvature also induces
significant variations in lamins, chromatin condensation and cell proliferation
rate in folded epithelial tissues. Together, this work identifies active cell
mechanics and nuclear mechanoadaptation as the key players of the mechanistic
regulation of epithelia to substrate curvature.

text: How information is created, shared and consumed has changed rapidly in recent
decades, in part thanks to new social platforms and technologies on the web. With
ever-larger amounts of unstructured and limited labels, organizing and reconciling
information from different sources and modalities is a central challenge in machine
learning. This cutting-edge tutorial aims to introduce the multimodal entailment
task, which can be useful for detecting semantic alignments when a single modality
alone does not suffice for a whole content understanding. Starting with a brief
overview of natural language processing, computer vision, structured data and
neural graph learning, we lay the foundations for the multimodal sections to follow.
We then discuss recent multimodal learning literature covering visual, audio and
language streams, and explore case studies focusing on tasks which require fine-grained
understanding of visual and linguistic semantics question answering, veracity
and hatred classification. Finally, we introduce a new dataset for recognizing
multimodal entailment, exploring it in a hands-on collaborative section. Overall,
this tutorial gives an overview of multimodal learning, introduces a multimodal
entailment dataset, and encourages future research in the topic.
