text: "We consider the quantitative problem of obtaining lower-bounds on the probability
of termination of a given non-deterministic probabilistic program. Specifically,
given a non-termination threshold p∈[0,1], we aim for certificates proving that
the program terminates with probability at least 1−p. The basic idea of our approach
is to find a terminating stochastic invariant, i.e. a subset SI of program states
such that (i) the probability of the program ever leaving SI is no more than p,
and (ii) almost-surely, the program either leaves SI or terminates.\r\n\r\nWhile
stochastic invariants are already well-known, we provide the first proof that
the idea above is not only sound, but also complete for quantitative termination
analysis. We then introduce a novel sound and complete characterization of stochastic
invariants that enables template-based approaches for easy synthesis of quantitative
termination certificates, especially in affine or polynomial forms. Finally, by
combining this idea with the existing martingale-based methods that are relatively
complete for qualitative termination analysis, we obtain the first automated,
sound, and relatively complete algorithm for quantitative termination analysis.
Notably, our completeness guarantees for quantitative termination analysis are
as strong as the best-known methods for the qualitative variant.\r\n\r\nOur prototype
implementation demonstrates the effectiveness of our approach on various probabilistic
programs. We also demonstrate that our algorithm certifies lower bounds on termination
probability for probabilistic programs that are beyond the reach of previous methods."

text: 'Sexual antagonism is a common hypothesis for driving the evolution of sex
chromosomes, whereby recombination suppression is favored between sexually antagonistic
loci and the sex-determining locus to maintain beneficial combinations of alleles.
This results in the formation of a sex-determining region. Chromosomal inversions
may contribute to recombination suppression but their precise role in sex chromosome
evolution remains unclear. Because local adaptation is frequently facilitated
through the suppression of recombination between adaptive loci by chromosomal
inversions, there is potential for inversions that cover sex-determining regions
to be involved in local adaptation as well, particularly if habitat variation
creates environment-dependent sexual antagonism. With these processes in mind,
we investigated sex determination in a well-studied example of local adaptation
within a species: the intertidal snail, Littorina saxatilis. Using SNP data from
a Swedish hybrid zone, we find novel evidence for a female-heterogametic sex determination
system that is restricted to one ecotype. Our results suggest that four putative
chromosomal inversions, two previously described and two newly discovered, span
the putative sex chromosome pair. We determine their differing associations with
sex, which suggest distinct strata of differing ages. The same inversions are
found in the second ecotype but do not show any sex association. The striking
disparity in inversion-sex associations between ecotypes that are connected by
gene flow across a habitat transition that is just a few meters wide indicates
a difference in selective regime that has produced a distinct barrier to the spread
of the newly discovered sex-determining region between ecotypes. Such sex chromosome-environment
interactions have not previously been uncovered in L. saxatilis and are known
in few other organisms. A combination of both sex-specific selection and divergent
natural selection is required to explain these highly unusual patterns.'

text: The Tibetan plateau (TP) plays an important role in the Asian summer monsoon
(ASM) dynamics as a heat source during the pre-monsoon and monsoon seasons. A
significant contribution to the pre-monsoon TP heating comes from the sensible
heat flux (SHF), which depend on the surface properties. A glaciated surface would
have a different SHF compared to a non-glaciated surface. Therefore, the TP glaciers
potentially can also impact the hydrological cycle in the Asian continent by impacting
the ASM rainfall via its contribution to the total plateau heating. However, there
is no assessment of this putative link available. Here, we attempt to qualitatively
study the role of TP glaciers on ASM by analyzing the sensitivity of an atmospheric
model to the absence of TP glaciers. We find that the absence of the glaciers
is most felt in climatologically less snowy regions (which are mostly located
at the south-central boundary of the TP during the pre-monsoon season), which
leads to positive SHF anomalies. The resulting positive diabatic heating leads
to rising air in the eastern TP and sinking air in the western TP. This altered
circulation in turn leads to a positive SHF memory in the western TP, which persists
until the end of the monsoon season. The impact of SHF anomalies on diabatic heating
results in a large-scale subsidence over the ASM domain. The net result is a reduced
seasonal ASM rainfall. Given the relentless warming and the vulnerability of glaciers
to warming, this is another flag in the ASM variability and change that needs
further attention.

text: Changes in the short-term dynamics of excitatory synapses over development
have been observed throughout cortex, but their purpose and consequences remain
unclear. Here, we propose that developmental changes in synaptic dynamics buffer
the effect of slow inhibitory long-term plasticity, allowing for continuously
stable neural activity. Using computational modeling we demonstrate that early
in development excitatory short-term depression quickly stabilises neural activity,
even in the face of strong, unbalanced excitation. We introduce a model of the
commonly observed developmental shift from depression to facilitation and show
that neural activity remains stable throughout development, while inhibitory synaptic
plasticity slowly balances excitation, consistent with experimental observations.
Our model predicts changes in the input responses from phasic to phasic-and-tonic
and more precise spike timings. We also observe a gradual emergence of short-lasting
memory traces governed by short-term plasticity development. We conclude that
the developmental depression-to-facilitation shift may control excitation-inhibition
balance throughout development with important functional consequences.

text: World models learn behaviors in a latent imagination space to enhance the
sample-efficiency of deep reinforcement learning (RL) algorithms. While learning
world models for high-dimensional observations (e.g., pixel inputs) has become
practicable on standard RL benchmarks and some games, their effectiveness in real-world
robotics applications has not been explored. In this paper, we investigate how
such agents generalize to real-world autonomous vehicle control tasks, where advanced
model-free deep RL algorithms fail. In particular, we set up a series of time-lap
tasks for an F1TENTH racing robot, equipped with a high-dimensional LiDAR sensor,
on a set of test tracks with a gradual increase in their complexity. In this continuous-control
setting, we show that model-based agents capable of learning in imagination substantially
outperform model-free agents with respect to performance, sample efficiency, successful
task completion, and generalization. Moreover, we show that the generalization
ability of model-based agents strongly depends on the choice of their observation
model. We provide extensive empirical evidence for the effectiveness of world
models provided with long enough memory horizons in sim2real tasks.

text: We characterize the capacity for the discrete-time arbitrarily varying channel
with discrete inputs, outputs, and states when (a) the encoder and decoder do
not share common randomness, (b) the input and state are subject to cost constraints,
(c) the transition matrix of the channel is deterministic given the state, and
(d) at each time step the adversary can only observe the current and past channel
inputs when choosing the state at that time. The achievable strategy involves
stochastic encoding together with list decoding and a disambiguation step. The
converse uses a two-phase "babble-and-push" strategy where the adversary chooses
the state randomly in the first phase, list decodes the output, and then chooses
state inputs to symmetrize the channel in the second phase. These results generalize
prior work on specific channels models (additive, erasure) to general discrete
alphabets and models.

text: This paper is eligible for the Jack Keil Wolf ISIT Student Paper Award. We
generalize a previous framework for designing utility-optimal differentially private
(DP) mechanisms via graphs, where datasets are vertices in the graph and edges
represent dataset neighborhood. The boundary set contains datasets where an individual’s
response changes the binary-valued query compared to its neighbors. Previous work
was limited to the homogeneous case where the privacy parameter ε across all datasets
was the same and the mechanism at boundary datasets was identical. In our work,
the mechanism can take different distributions at the boundary and the privacy
parameter ε is a function of neighboring datasets, which recovers an earlier definition
of personalized DP as special case. The problem is how to extend the mechanism,
which is only defined at the boundary set, to other datasets in the graph in a
computationally efficient and utility optimal manner. Using the concept of strongest
induced DP condition we solve this problem efficiently in polynomial time (in
the size of the graph).

text: We consider the problem of communication over adversarial channels with feedback.
Two parties comprising sender Alice and receiver Bob seek to communicate reliably.
An adversary James observes Alice's channel transmission entirely and chooses,
maliciously, its additive channel input or jamming state thereby corrupting Bob's
observation. Bob can communicate over a one-way reverse link with Alice; we assume
that transmissions over this feedback link cannot be corrupted by James. Our goal
in this work is to study the optimum throughput or capacity over such channels
with feedback. We first present results for the quadratically-constrained additive
channel where communication is known to be impossible when the noise-to-signal
(power) ratio (NSR) is at least 1. We present a novel achievability scheme to
establish that positive rate communication is possible even when the NSR is as
high as 8/9. We also present new converse upper bounds on the capacity of this
channel under potentially stochastic encoders and decoders. We also study feedback
communication over the more widely studied q-ary alphabet channel under additive
noise. For the q -ary channel, where q > 2, it is well known that capacity is
positive under full feedback if and only if the adversary can corrupt strictly
less than half the transmitted symbols. We generalize this result and show that
the same threshold holds for positive rate communication when the noiseless feedback
may only be partial; our scheme employs a stochastic decoder. We extend this characterization,
albeit partially, to fully deterministic schemes under partial noiseless feedback.
We also present new converse upper bounds for q-ary channels under full feedback,
where the encoder and/or decoder may privately randomize. Our converse results
bring to the fore an interesting alternate expression for the well known converse
bound for the q—ary channel under full feedback which, when specialized to the
binary channel, also equals its known capacity.

text: We study the problem of high-dimensional multiple packing in Euclidean space.
Multiple packing is a natural generalization of sphere packing and is defined
as follows. Let N > 0 and L∈Z≥2. A multiple packing is a set C of points in Rn
such that any point in Rn lies in the intersection of at most L – 1 balls of radius
nN−−−√ around points in C. Given a well-known connection with coding theory, multiple
packings can be viewed as the Euclidean analog of list-decodable codes, which
are well-studied for finite fields. In this paper, we exactly pin down the asymptotic
density of (expurgated) Poisson Point Processes under a stronger notion called
average-radius multiple packing. To this end, we apply tools from high-dimensional
geometry and large deviation theory. This gives rise to the best known lower bound
on the largest multiple packing density. Our result corrects a mistake in a previous
paper by Blinovsky [Bli05].

text: We study the problem of high-dimensional multiple packing in Euclidean space.
Multiple packing is a natural generalization of sphere packing and is defined
as follows. Let P, N > 0 and L∈Z≥2. A multiple packing is a set C of points in
Bn(0–,nP−−−√) such that any point in ℝ n lies in the intersection of at most L
– 1 balls of radius nN−−−√ around points in C. 1 In this paper, we derive two
lower bounds on the largest possible density of a multiple packing. These bounds
are obtained through a stronger notion called average-radius multiple packing.
Specifically, we exactly pin down the asymptotics of (expurgated) Gaussian codes
and (expurgated) spherical codes under average-radius multiple packing. To this
end, we apply tools from high-dimensional geometry and large deviation theory.
The bound for spherical codes matches the previous best known bound which was
obtained for the standard (weaker) notion of multiple packing through a curious
connection with error exponents [Bli99], [ZV21]. The bound for Gaussian codes
suggests that they are strictly inferior to spherical codes.

text: We consider the problem of coded distributed computing using polar codes.
The average execution time of a coded computing system is related to the error
probability for transmission over the binary erasure channel in recent work by
Soleymani, Jamali and Mahdavifar, where the performance of binary linear codes
is investigated. In this paper, we focus on polar codes and unveil a connection
between the average execution time and the scaling exponent μ of the family of
codes. In the finite-length characterization of polar codes, the scaling exponent
is a key object capturing the speed of convergence to capacity. In particular,
we show that (i) the gap between the normalized average execution time of polar
codes and that of optimal MDS codes is O(n –1/μ ), and (ii) this upper bound can
be improved to roughly O(n –1/2 ) by considering polar codes with large kernels.
We conjecture that these bounds could be improved to O(n –2/μ ) and O(n –1 ),
respectively, and provide a heuristic argument as well as numerical evidence supporting
this view.

text: Transcription of the ribosomal RNA precursor by RNA polymerase (Pol) I is
a major determinant of cellular growth, and dysregulation is observed in many
cancer types. Here, we present the purification of human Pol I from cells carrying
a genomic GFP fusion on the largest subunit allowing the structural and functional
analysis of the enzyme across species. In contrast to yeast, human Pol I carries
a single-subunit stalk, and in vitro transcription indicates a reduced proofreading
activity. Determination of the human Pol I cryo-EM reconstruction in a close-to-native
state rationalizes the effects of disease-associated mutations and uncovers an
additional domain that is built into the sequence of Pol I subunit RPA1. This
“dock II” domain resembles a truncated HMG box incapable of DNA binding which
may serve as a downstream transcription factor–binding platform in metazoans.
Biochemical analysis, in situ modelling, and ChIP data indicate that Topoisomerase
2a can be recruited to Pol I via the domain and cooperates with the HMG box domain–containing
factor UBF. These adaptations of the metazoan Pol I transcription system may allow
efficient release of positive DNA supercoils accumulating downstream of the transcription
bubble.

text: Directionality in the intercellular transport of the plant hormone auxin is
determined by polar plasma membrane localization of PIN-FORMED (PIN) auxin transport
proteins. However, apart from PIN phosphorylation at conserved motifs, no further
determinants explicitly controlling polar PIN sorting decisions have been identified.
Here we present Arabidopsis WAVY GROWTH 3 (WAV3) and closely related RING-finger
E3 ubiquitin ligases, whose loss-of-function mutants show a striking apical-to-basal
polarity switch in PIN2 localization in root meristem cells. WAV3 E3 ligases function
as essential determinants for PIN polarity, acting independently from PINOID/WAG-dependent
PIN phosphorylation. They antagonize ectopic deposition of de novo synthesized
PIN proteins already immediately following completion of cell division, presumably
via preventing PIN sorting into basal, ARF GEF-mediated trafficking. Our findings
reveal an involvement of E3 ligases in the selective targeting of apically localized
PINs in higher plants.

text: Strigolactones (SLs) are a class of phytohormones that regulate plant shoot
branching and adventitious root development. However, little is known regarding
the role of SLs in controlling the behavior of the smallest unit of the organism,
the single cell. Here, taking advantage of a classic single-cell model offered
by the cotton (Gossypium hirsutum) fiber cell, we show that SLs, whose biosynthesis
is fine-tuned by gibberellins (GAs), positively regulate cell elongation and cell
wall thickness by promoting the biosynthesis of very-long-chain fatty acids (VLCFAs)
and cellulose, respectively. Furthermore, we identified two layers of transcription
factors (TFs) involved in the hierarchical regulation of this GA-SL crosstalk.
The top-layer TF GROWTH-REGULATING FACTOR 4 (GhGRF4) directly activates expression
of the SL biosynthetic gene DWARF27 (D27) to increase SL accumulation in fiber
cells and GAs induce GhGRF4 expression. SLs induce the expression of four second-layer
TF genes (GhNAC100-2, GhBLH51, GhGT2, and GhB9SHZ1), which transmit SL signals
downstream to two ketoacyl-CoA synthase genes (KCS) and three cellulose synthase
(CesA) genes by directly activating their transcription. Finally, the KCS and
CesA enzymes catalyze the biosynthesis of very long chain fatty acids and cellulose,
respectively, to regulate development of high-grade cotton fibers. In addition
to providing a theoretical basis for cotton fiber improvement, our results shed
light on SL signaling in plant development at the single-cell level.

text: 'Polar auxin transport is unique to plants and coordinates their growth and
development1,2. The PIN-FORMED (PIN) auxin transporters exhibit highly asymmetrical
localizations at the plasma membrane and drive polar auxin transport3,4; however,
their structures and transport mechanisms remain largely unknown. Here, we report
three inward-facing conformation structures of Arabidopsis thaliana PIN1: the
apo state, bound to the natural auxin indole-3-acetic acid (IAA), and in complex
with the polar auxin transport inhibitor N-1-naphthylphthalamic acid (NPA). The
transmembrane domain of PIN1 shares a conserved NhaA fold5. In the substrate-bound
structure, IAA is coordinated by both hydrophobic stacking and hydrogen bonding.
NPA competes with IAA for the same site at the intracellular pocket, but with
a much higher affinity. These findings inform our understanding of the substrate
recognition and transport mechanisms of PINs and set up a framework for future
research on directional auxin transport, one of the most crucial processes underlying
plant development.'

text: We present a divergent strategy for the fluorination of phenylacetic acid
derivatives that is induced by a charge-transfer complex between Selectfluor and
4-(dimethylamino)pyridine. A comprehensive investigation of the conditions revealed
a critical role of the solvent on the reaction outcome. In the presence of water,
decarboxylative fluorination through a single-electron oxidation is dominant.
Non-aqueous conditions result in the clean formation of α-fluoro-α-arylcarboxylic
acids.

J Math Anal 54(1):114–172, 2022. https://doi.org/10.1137/21M1424925) concerning
convergence rates for solutions of the Allen–Cahn equation with a nonlinear Robin
boundary condition towards evolution by mean curvature flow with constant contact
angle. More precisely, in the present work we manage to remove the perturbative
assumption on the contact angle being close to 90∘. We establish under usual double-well
type assumptions on the potential and for a certain class of boundary energy densities
the sub-optimal convergence rate of order ε12 for general contact angles α∈(0,π).
For a very specific form of the boundary energy density, we even obtain from our
methods a sharp convergence rate of order ε; again for general contact angles
α∈(0,π). Our proof deviates from the popular strategy based on rigorous asymptotic
expansions and stability estimates for the linearized Allen–Cahn operator. Instead,
we follow the recent approach by Fischer et al. (SIAM J Math Anal 52(6):6222–6233,
2020. https://doi.org/10.1137/20M1322182), thus relying on a relative entropy
technique. We develop a careful adaptation of their approach in order to encode
the constant contact angle condition. In fact, we perform this task at the level
of the notion of gradient flow calibrations. This concept was recently introduced
in the context of weak-strong uniqueness for multiphase mean curvature flow by
Fischer et al. (arXiv:2003.05478v2).

text: Proximity-dependent protein labeling provides a powerful in vivo strategy
to characterize the interactomes of specific proteins. We previously optimized
a proximity labeling protocol for Caenorhabditis elegans using the highly active
biotin ligase TurboID. A significant constraint on the sensitivity of TurboID
is the presence of abundant endogenously biotinylated proteins that take up bandwidth
in the mass spectrometer, notably carboxylases that use biotin as a cofactor.
In C. elegans, these comprise POD-2/acetyl-CoA carboxylase alpha, PCCA-1/propionyl-CoA
carboxylase alpha, PYC-1/pyruvate carboxylase, and MCCC-1/methylcrotonyl-CoA carboxylase
alpha. Here, we developed ways to remove these carboxylases prior to streptavidin
purification and mass spectrometry by engineering their corresponding genes to
add a C-terminal His10 tag. This allows us to deplete them from C. elegans lysates
using immobilized metal affinity chromatography. To demonstrate the method's efficacy,
we use it to expand the interactome map of the presynaptic active zone protein
ELKS-1. We identify many known active zone proteins, including UNC-10/RIM, SYD-2/liprin-alpha,
SAD-1/BRSK1, CLA-1/CLArinet, C16E9.2/Sentryn, as well as previously uncharacterized
potentially synaptic proteins such as the ortholog of human angiomotin, F59C12.3
and the uncharacterized protein R148.3. Our approach provides a quick and inexpensive
solution to a common contaminant problem in biotin-dependent proximity labeling.
The approach may be applicable to other model organisms and will enable deeper
and more complete analysis of interactors for proteins of interest.

text: Neuronal networks encode information through patterns of activity that define
the networks’ function. The neurons’ activity relies on specific connectivity
structures, yet the link between structure and function is not fully understood.
Here, we tackle this structure-function problem with a new conceptual approach.
Instead of manipulating the connectivity directly, we focus on upper triangular
matrices, which represent the network dynamics in a given orthonormal basis obtained
by the Schur decomposition. This abstraction allows us to independently manipulate
the eigenspectrum and feedforward structures of a connectivity matrix. Using this
method, we describe a diverse repertoire of non-normal transient amplification,
and to complement the analysis of the dynamical regimes, we quantify the geometry
of output trajectories through the effective rank of both the eigenvector and
the dynamics matrices. Counter-intuitively, we find that shrinking the eigenspectrum’s
imaginary distribution leads to highly amplifying regimes in linear and long-lasting
dynamics in nonlinear networks. We also find a trade-off between amplification
and dimensionality of neuronal dynamics, i.e., trajectories in neuronal state-space.
Networks that can amplify a large number of orthogonal initial conditions produce
neuronal trajectories that lie in the same subspace of the neuronal state-space.
Finally, we examine networks of excitatory and inhibitory neurons. We find that
the strength of global inhibition is directly linked with the amplitude of amplification,
such that weakening inhibitory weights also decreases amplification, and that
the eigenspectrum’s imaginary distribution grows with an increase in the ratio
between excitatory-to-inhibitory and excitatory-to-excitatory connectivity strengths.
Consequently, the strength of global inhibition reveals itself as a strong signature
for amplification and a potential control mechanism to switch dynamical regimes.
Our results shed a light on how biological networks, i.e., networks constrained
by Dale’s law, may be optimised for specific dynamical regimes.
