text: In [10] Nam proved a Lieb–Thirring Inequality for the kinetic energy of a
fermionic quantum system, with almost optimal (semi-classical) constant and a
gradient correction term. We present a stronger version of this inequality, with
a much simplified proof. As a corollary we obtain a simple proof of the original
Lieb–Thirring inequality.

text: Toscana virus is a major cause of arboviral disease in humans in the Mediterranean
basin during summer. However, early virus-host cell interactions and entry mechanisms
remain poorly characterized. Investigating iPSC-derived human neurons and cell
lines, we found that virus binding to the cell surface was specific, and 50% of
bound virions were endocytosed within 10 min. Virions entered Rab5a+ early endosomes
and, subsequently, Rab7a+ and LAMP-1+ late endosomal compartments. Penetration
required intact late endosomes and occurred within 30 min following internalization.
Virus entry relied on vacuolar acidification, with an optimal pH for viral membrane
fusion at pH 5.5. The pH threshold increased to 5.8 with longer pre-exposure of
virions to the slightly acidic pH in early endosomes. Strikingly, the particles
remained infectious after entering late endosomes with a pH below the fusion threshold.
Overall, our study establishes Toscana virus as a late-penetrating virus and reveals
an atypical use of vacuolar acidity by this virus to enter host cells.

text: There is currently little evidence that the genetic basis of human phenotype
varies significantly across the lifespan. However, time-to-event phenotypes are
understudied and can be thought of as reflecting an underlying hazard, which is
unlikely to be constant through life when values take a broad range. Here, we
find that 74% of 245 genome-wide significant genetic associations with age at
natural menopause (ANM) in the UK Biobank show a form of age-specific effect.
Nineteen of these replicated discoveries are identified only by our modeling framework,
which determines the time dependency of DNA-variant age-at-onset associations
without a significant multiple-testing burden. Across the range of early to late
menopause, we find evidence for significantly different underlying biological
pathways, changes in the signs of genetic correlations of ANM to health indicators
and outcomes, and differences in inferred causal relationships. We find that DNA
damage response processes only act to shape ovarian reserve and depletion for
women of early ANM. Genetically mediated delays in ANM were associated with increased
relative risk of breast cancer and leiomyoma at all ages and with high cholesterol
and heart failure for late-ANM women. These findings suggest that a better understanding
of the age dependency of genetic risk factor relationships among health indicators
and outcomes is achievable through appropriate statistical modeling of large-scale
biobank data.

text: In this work, a generalized, adapted Numerov implementation capable of determining
band structures of periodic quantum systems is outlined. Based on the input potential,
the presented approach numerically solves the Schrödinger equation in position
space at each momentum space point. Thus, in addition to the band structure, the
method inherently provides information about the state functions and probability
densities in position space at each momentum space point considered. The generalized,
adapted Numerov framework provided reliable estimates for a variety of increasingly
complex test suites in one, two, and three dimensions. The accuracy of the proposed
methodology was benchmarked against results obtained for the analytically solvable
Kronig-Penney model. Furthermore, the presented numerical solver was applied to
a model potential representing a 2D optical lattice being a challenging application
relevant, for example, in the field of quantum computing.

text: Living tissues are characterized by an intrinsically mechanochemical interplay
of active physical forces and complex biochemical signaling pathways. Either feature
alone can give rise to complex emergent phenomena, for example, mechanically driven
glassy dynamics and rigidity transitions, or chemically driven reaction-diffusion
instabilities. An important question is how to quantitatively assess the contribution
of these different cues to the large-scale dynamics of biological materials. We
address this in Madin-Darby canine kidney (MDCK) monolayers, considering both
mechanochemical feedback between extracellular signal-regulated kinase (ERK) signaling
activity and cellular density as well as a mechanically active tissue rheology
via a self-propelled vertex model. We show that the relative strength of active
migration forces to mechanochemical couplings controls a transition from a uniform
active glass to periodic spatiotemporal waves. We parametrize the model from published
experimental data sets on MDCK monolayers and use it to make new predictions on
the correlation functions of cellular dynamics and the dynamics of topological
defects associated with the oscillatory phase of cells. Interestingly, MDCK monolayers
are best described by an intermediary parameter region in which both mechanochemical
couplings and noisy active propulsion have a strong influence on the dynamics.
Finally, we study how tissue rheology and ERK waves produce feedback on one another
and uncover a mechanism via which tissue fluidity can be controlled by mechanochemical
waves at both the local and global levels.

text: In nature, proteins that switch between two conformations in response to environmental
stimuli structurally transduce biochemical information in a manner analogous to
how transistors control information flow in computing devices. Designing proteins
with two distinct but fully structured conformations is a challenge for protein
design as it requires sculpting an energy landscape with two distinct minima.
Here we describe the design of “hinge” proteins that populate one designed state
in the absence of ligand and a second designed state in the presence of ligand.
X-ray crystallography, electron microscopy, double electron-electron resonance
spectroscopy, and binding measurements demonstrate that despite the significant
structural differences the two states are designed with atomic level accuracy
and that the conformational and binding equilibria are closely coupled.

text: Growth factors and cytokines signal by binding to the extracellular domains
of their receptors and drive association and transphosphorylation of the receptor
intracellular tyrosine kinase domains, initiating downstream signaling cascades.
To enable systematic exploration of how receptor valency and geometry affects
signaling outcomes, we designed cyclic homo-oligomers with up to 8 subunits using
repeat protein building blocks that can be modularly extended. By incorporating
a de novo designed fibroblast growth-factor receptor (FGFR) binding module into
these scaffolds, we generated a series of synthetic signaling ligands that exhibit
potent valency- and geometry-dependent Ca2+ release and MAPK pathway activation.
The high specificity of the designed agonists reveal distinct roles for two FGFR
splice variants in driving endothelial and mesenchymal cell fates during early
vascular development. The ability to incorporate receptor binding domains and
repeat extensions in a modular fashion makes our designed scaffolds broadly useful
for probing and manipulating cellular signaling pathways.

text: To respond to auxin, the chief orchestrator of their multicellularity, plants
evolved multiple receptor systems and signal transduction cascades. Despite decades
of research, however, we are still lacking a satisfactory synthesis of various
auxin signaling mechanisms. The chief discrepancy and historical controversy of
the field is that of rapid and slow auxin effects on plant physiology and development.
How is it possible that ions begin to trickle across the plasma membrane as soon
as auxin enters the cell, even though the best-characterized transcriptional auxin
pathway can take effect only after tens of minutes? Recently, unexpected progress
has been made in understanding this and other unknowns of auxin signaling. We
provide a perspective on these exciting developments and concepts whose general
applicability might have ramifications beyond auxin signaling.
acknowledgement: The opening quote is not intended to reflect any political views
of the authors. The authors by no means endorse the rhetoric of Donald Rumsfeld
or the 2003 invasion of Iraq by the United States. Nevertheless, Rumsfeld's quote
led to both public and academic debates on the concept of known and unknown unknowns,
which can be applied to the recent unexpected developments in the auxin signaling
field. We thank Linlin Qi and Huihuang Chen for their suggestions on figure presentation
and inspiring discussions of TIR1/AFB signaling. Finally, we thank Aroosa Hussain

text: The execution of cognitive functions requires coordinated circuit activity
across different brain areas that involves the associated firing of neuronal assemblies.
Here, we tested the circuit mechanism behind assembly interactions between the
hippocampus and the medial prefrontal cortex (mPFC) of adult rats by recording
neuronal populations during a rule-switching task. We identified functionally
coupled CA1-mPFC cells that synchronized their activity beyond that expected from
common spatial coding or oscillatory firing. When such cell pairs fired together,
the mPFC cell strongly phase locked to CA1 theta oscillations and maintained consistent
theta firing phases, independent of the theta timing of their CA1 counterpart.
These functionally connected CA1-mPFC cells formed interconnected assemblies.
While firing together with their CA1 assembly partners, mPFC cells fired along
specific theta sequences. Our results suggest that upregulated theta oscillatory
firing of mPFC cells can signal transient interactions with specific CA1 assemblies,
thus enabling distributed computations.

text: During apoptosis, caspases degrade 8 out of ~30 nucleoporins to irreversibly
demolish the nuclear pore complex. However, for poorly understood reasons, caspases
are also activated during cell differentiation. Here, we show that sublethal activation
of caspases during myogenesis results in the transient proteolysis of four peripheral
Nups and one transmembrane Nup. ‘Trimmed’ NPCs become nuclear export-defective,
and we identified in an unbiased manner several classes of cytoplasmic, plasma
membrane, and mitochondrial proteins that rapidly accumulate in the nucleus. NPC
trimming by non-apoptotic caspases was also observed in neurogenesis and endoplasmic
reticulum stress. Our results suggest that caspases can reversibly modulate nuclear
transport activity, which allows them to function as agents of cell differentiation
and adaptation at sublethal levels.

text: Clathrin-mediated vesicle trafficking plays central roles in post-Golgi transport.
In yeast (Saccharomyces cerevisiae), the AP-1 complex and GGA adaptors are predicted
to generate distinct transport vesicles at the trans-Golgi network (TGN), and
the epsin-related proteins Ent3p and Ent5p (collectively Ent3p/5p) act as accessories
for these adaptors. Recently, we showed that vesicle transport from the TGN is
crucial for yeast Rab5 (Vps21p)-mediated endosome formation, and that Ent3p/5p
are crucial for this process, whereas AP-1 and GGA adaptors are dispensable. However,
these observations were incompatible with previous studies showing that these
adaptors are required for Ent3p/5p recruitment to the TGN, and thus the overall
mechanism responsible for regulation of Vps21p activity remains ambiguous. Here,
we investigated the functional relationships between clathrin adaptors in post-Golgi-mediated
Vps21p activation. We show that AP-1 disruption in the ent3Δ5Δ mutant impaired
transport of the Vps21p guanine nucleotide exchange factor Vps9p transport to
the Vps21p compartment and severely reduced Vps21p activity. Additionally, GGA
adaptors, the phosphatidylinositol-4-kinase Pik1p and Rab11 GTPases Ypt31p and
Ypt32p were found to have partially overlapping functions for recruitment of AP-1
and Ent3p/5p to the TGN. These findings suggest a distinct role of clathrin adaptors
for Vps21p activation in the TGN–endosome trafficking pathway.

text: "Markov decision processes can be viewed as transformers of probability distributions.
While this view is useful from a practical standpoint to reason about trajectories
of distributions, basic reachability and safety problems are known to be computationally
intractable (i.e., Skolem-hard) to solve in such models. Further, we show that
even for simple examples of MDPs, strategies for safety objectives over distributions
can require infinite memory and randomization.\r\nIn light of this, we present
a novel overapproximation approach to synthesize strategies in an MDP, such that
a safety objective over the distributions is met. More precisely, we develop a
new framework for template-based synthesis of certificates as affine distributional
and inductive invariants for safety objectives in MDPs. We provide two algorithms
within this framework. One can only synthesize memoryless strategies, but has
relative completeness guarantees, while the other can synthesize general strategies.
The runtime complexity of both algorithms is in PSPACE. We implement these algorithms
and show that they can solve several non-trivial examples."

text: "Probabilistic recurrence relations (PRRs) are a standard formalism for describing
the runtime of a randomized algorithm. Given a PRR and a time limit κ, we consider
the tail probability Pr[T≥κ], i.e., the probability that the randomized runtime
T of the PRR exceeds κ. Our focus is the formal analysis of tail bounds that aims
at finding a tight asymptotic upper bound u≥Pr[T≥κ]. To address this problem,
the classical and most well-known approach is the cookbook method by Karp (JACM
1994), while other approaches are mostly limited to deriving tail bounds of specific
PRRs via involved custom analysis.\r\nIn this work, we propose a novel approach
for deriving the common exponentially-decreasing tail bounds for PRRs whose preprocessing
time and random passed sizes observe discrete or (piecewise) uniform distribution
and whose recursive call is either a single procedure call or a divide-and-conquer.
We first establish a theoretical approach via Markov’s inequality, and then instantiate
the theoretical approach with a template-based algorithmic approach via a refined
treatment of exponentiation. Experimental evaluation shows that our algorithmic
approach is capable of deriving tail bounds that are (i) asymptotically tighter
than Karp’s method, (ii) match the best-known manually-derived asymptotic tail
bound for QuickSelect, and (iii) is only slightly worse (with a loglogn factor)
than the manually-proven optimal asymptotic tail bound for QuickSort. Moreover,
our algorithmic approach handles all examples (including realistic PRRs such as
QuickSort, QuickSelect, DiameterComputation, etc.) in less than 0.1 s, showing
that our approach is efficient in practice."

text: "We study multigraphs whose edge-sets are the union of three perfect matchings,
M1, M2, and M3. Given such a graph G and any a1; a2; a3 2 N with a1 +a2 +a3 6
n - 2, we show there exists a matching M of G with jM \\ Mij = ai for each i 2
f1; 2; 3g. The bound n - 2 in the theorem is best possible in general. We conjecture
however that if G is bipartite, the same result holds with n - 2 replaced by n
- 1. We give a construction that shows such a result would be tight. We\r\nalso
make a conjecture generalising the Ryser-Brualdi-Stein conjecture with colour\r\nmultiplicities."

text: The development of two-dimensional materials has resulted in a diverse range
of novel, high-quality compounds with increasing complexity. A key requirement
for a comprehensive quantitative theory is the accurate determination of these
materials' band structure parameters. However, this task is challenging due to
the intricate band structures and the indirect nature of experimental probes.
In this work, we introduce a general framework to derive band structure parameters
from experimental data using deep neural networks. We applied our method to the
penetration field capacitance measurement of trilayer graphene, an effective probe
of its density of states. First, we demonstrate that a trained deep network gives
accurate predictions for the penetration field capacitance as a function of tight-binding
parameters. Next, we use the fast and accurate predictions from the trained network
to automatically determine tight-binding parameters directly from experimental
data, with extracted parameters being in a good agreement with values in the literature.
We conclude by discussing potential applications of our method to other materials
and experimental techniques beyond penetration field capacitance.

text: We demonstrate the possibility of a coupling between the magnetization direction
of a ferromagnet and the tilting angle of adsorbed achiral molecules. To illustrate
the mechanism of the coupling, we analyze a minimal Stoner model that includes
Rashba spin–orbit coupling due to the electric field on the surface of the ferromagnet.
The proposed mechanism allows us to study magnetic anisotropy of the system with
an extended Stoner–Wohlfarth model and argue that adsorbed achiral molecules can
change magnetocrystalline anisotropy of the substrate. Our research aims to motivate
further experimental studies of the current-free chirality induced spin selectivity
effect involving both enantiomers.

text: "As causal ground truth is incredibly rare, causal discovery algorithms are\r\ncommonly
only evaluated on simulated data. This is concerning, given that\r\nsimulations
reflect common preconceptions about generating processes regarding\r\nnoise distributions,
model classes, and more. In this work, we propose a novel\r\nmethod for falsifying
the output of a causal discovery algorithm in the absence\r\nof ground truth.
Our key insight is that while statistical learning seeks\r\nstability across subsets
of data points, causal learning should seek stability\r\nacross subsets of variables.
Motivated by this insight, our method relies on a\r\nnotion of compatibility between
causal graphs learned on different subsets of\r\nvariables. We prove that detecting
incompatibilities can falsify wrongly\r\ninferred causal relations due to violation
of assumptions or errors from finite\r\nsample effects. Although passing such
compatibility tests is only a necessary\r\ncriterion for good performance, we
argue that it provides strong evidence for\r\nthe causal models whenever compatibility
entails strong implications for the\r\njoint distribution. We also demonstrate
experimentally that detection of\r\nincompatibilities can aid in causal model
selection."

text: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
dynamical behavior and invite their further theoretical and experimental studies.

text: Lateral roots are typically maintained at non-vertical angles with respect
to gravity. These gravitropic setpoint angles are intriguing because their maintenance
requires that roots are able to effect growth response both with and against the
gravity vector, a phenomenon previously attributed to gravitropism acting against
an antigravitropic offset mechanism. Here we show how the components mediating
gravitropism in the vertical primary root—PINs and phosphatases acting upon them—are
reconfigured in their regulation such that lateral root growth at a range of angles
can be maintained. We show that the ability of Arabidopsis lateral roots to bend
both downward and upward requires the generation of auxin asymmetries and is driven
by angle-dependent variation in downward gravitropic auxin flux acting against
angle-independent upward, antigravitropic flux. Further, we demonstrate a symmetry
in auxin distribution in lateral roots at gravitropic setpoint angle that can
be traced back to a net, balanced polarization of PIN3 and PIN7 auxin transporters
in the columella. These auxin fluxes are shifted by altering PIN protein phosphoregulation
in the columella, either by introducing PIN3 phosphovariant versions or via manipulation
of levels of the phosphatase subunit PP2A/RCN1. Finally, we show that auxin, in
addition to driving lateral root directional growth, acts within the lateral root
columella to induce more vertical growth by increasing RCN1 levels, causing a
downward shift in PIN3 localization, thereby diminishing the magnitude of the
upward, antigravitropic auxin flux.
