text: "A common assumption in causal modeling posits that the data is generated
by a\r\nset of independent mechanisms, and algorithms should aim to recover this\r\nstructure.
Standard unsupervised learning, however, is often concerned with\r\ntraining a
single model to capture the overall distribution or aspects thereof.\r\nInspired
by clustering approaches, we consider mixtures of implicit generative\r\nmodels
that ``disentangle'' the independent generative mechanisms underlying\r\nthe data.
Relying on an additional set of discriminators, we propose a\r\ncompetitive training
procedure in which the models only need to capture the\r\nportion of the data
distribution from which they can produce realistic samples.\r\nAs a by-product,
each model is simpler and faster to train. We empirically show\r\nthat our approach
splits the training distribution in a sensible way and\r\nincreases the quality
of the generated samples."

text: 'Recent developments in automated tracking allow uninterrupted, high-resolution
recording of animal trajectories, sometimes coupled with the identification of
stereotyped changes of body pose or other behaviors of interest. Analysis and
interpretation of such data represents a challenge: the timing of animal behaviors
may be stochastic and modulated by kinematic variables, by the interaction with
the environment or with the conspecifics within the animal group, and dependent
on internal cognitive or behavioral state of the individual. Existing models for
collective motion typically fail to incorporate the discrete, stochastic, and
internal-state-dependent aspects of behavior, while models focusing on individual
animal behavior typically ignore the spatial aspects of the problem. Here we propose
a probabilistic modeling framework to address this gap. Each animal can switch
stochastically between different behavioral states, with each state resulting
in a possibly different law of motion through space. Switching rates for behavioral
transitions can depend in a very general way, which we seek to identify from data,
on the effects of the environment as well as the interaction between the animals.
We represent the switching dynamics as a Generalized Linear Model and show that:
(i) forward simulation of multiple interacting animals is possible using a variant
of the Gillespie’s Stochastic Simulation Algorithm; (ii) formulated properly,
the maximum likelihood inference of switching rate functions is tractably solvable
by gradient descent; (iii) model selection can be used to identify factors that
modulate behavioral state switching and to appropriately adjust model complexity
to data. To illustrate our framework, we apply it to two synthetic models of animal
motion and to real zebrafish tracking data. '

text: Temperate bacteriophages integrate in bacterial genomes as prophages and represent
an important source of genetic variation for bacterial evolution, frequently transmitting
fitness-augmenting genes such as toxins responsible for virulence of major pathogens.
However, only a fraction of bacteriophage infections are lysogenic and lead to
prophage acquisition, whereas the majority are lytic and kill the infected bacteria.
Unless able to discriminate lytic from lysogenic infections, mechanisms of immunity
to bacteriophages are expected to act as a double-edged sword and increase the
odds of survival at the cost of depriving bacteria of potentially beneficial prophages.
We show that although restriction-modification systems as mechanisms of innate
immunity prevent both lytic and lysogenic infections indiscriminately in individual
bacteria, they increase the number of prophage-acquiring individuals at the population
level. We find that this counterintuitive result is a consequence of phage-host
population dynamics, in which restriction-modification systems delay infection
onset until bacteria reach densities at which the probability of lysogeny increases.
These results underscore the importance of population-level dynamics as a key
factor modulating costs and benefits of immunity to temperate bacteriophages

text: Many animals use antimicrobials to prevent or cure disease [1,2]. For example,
some animals will ingest plants with medicinal properties, both prophylactically
to prevent infection and therapeutically to self-medicate when sick. Antimicrobial
substances are also used as topical disinfectants, to prevent infection, protect
offspring and to sanitise their surroundings [1,2]. Social insects (ants, bees,
wasps and termites) build nests in environments with a high abundance and diversity
of pathogenic microorganisms — such as soil and rotting wood — and colonies are
often densely crowded, creating conditions that favour disease outbreaks. Consequently,
social insects have evolved collective disease defences to protect their colonies
from epidemics. These traits can be seen as functionally analogous to the immune
system of individual organisms [3,4]. This ‘social immunity’ utilises antimicrobials
to prevent and eradicate infections, and to keep the brood and nest clean. However,
these antimicrobial compounds can be harmful to the insects themselves, and it
is unknown how colonies prevent collateral damage when using them. Here, we demonstrate
that antimicrobial acids, produced by workers to disinfect the colony, are harmful
to the delicate pupal brood stage, but that the pupae are protected from the acids
by the presence of a silk cocoon. Garden ants spray their nests with an antimicrobial
poison to sanitize contaminated nestmates and brood. Here, Pull et al show that
they also prophylactically sanitise their colonies, and that the silk cocoon serves
as a barrier to protect developing pupae, thus preventing collateral damage during
nest sanitation.

text: We consider large random matrices X with centered, independent entries but
possibly di erent variances. We compute the normalized trace of f(X)g(X∗) for
f, g functions analytic on the spectrum of X. We use these results to compute
the long time asymptotics for systems of coupled di erential equations with random
coe cients. We show that when the coupling is critical, the norm squared of the
solution decays like t−1/2.

text: We construct quantizations of multiplicative hypertoric varieties using an
algebra of q-difference operators on affine space, where q is a root of unity
in C. The quantization defines a matrix bundle (i.e. Azumaya algebra) over the
multiplicative hypertoric variety and admits an explicit finite étale splitting.
The global sections of this Azumaya algebra is a hypertoric quantum group, and
we prove a localization theorem. We introduce a general framework of Frobenius
quantum moment maps and their Hamiltonian reductions; our results shed light on
an instance of this framework.

text: We address the problem of analyzing the reachable set of a polynomial nonlinear
continuous system by over-approximating the flowpipe of its dynamics. The common
approach to tackle this problem is to perform a numerical integration over a given
time horizon based on Taylor expansion and interval arithmetic. However, this
method results to be very conservative when there is a large difference in speed
between trajectories as time progresses. In this paper, we propose to use combinations
of barrier functions, which we call piecewise barrier tube (PBT), to over-approximate
flowpipe. The basic idea of PBT is that for each segment of a flowpipe, a coarse
box which is big enough to contain the segment is constructed using sampled simulation
and then in the box we compute by linear programming a set of barrier functions
(called barrier tube or BT for short) which work together to form a tube surrounding
the flowpipe. The benefit of using PBT is that (1) BT is independent of time and
hence can avoid being stretched and deformed by time; and (2) a small number of
BTs can form a tight over-approximation for the flowpipe, which means that the
computation required to decide whether the BTs intersect the unsafe set can be
reduced significantly. We implemented a prototype called PBTS in C++. Experiments
on some benchmark systems show that our approach is effective.

text: We investigate the quantum interference induced shifts between energetically
close states in highly charged ions, with the energy structure being observed
by laser spectroscopy. In this work, we focus on hyperfine states of lithiumlike
heavy-Z isotopes and quantify how much quantum interference changes the observed
transition frequencies. The process of photon excitation and subsequent photon
decay for the transition 2s→2p→2s is implemented with fully relativistic and full-multipole
frameworks, which are relevant for such relativistic atomic systems. We consider
the isotopes Pb79+207 and Bi80+209 due to experimental interest, as well as other
examples of isotopes with lower Z, namely Pr56+141 and Ho64+165. We conclude that
quantum interference can induce shifts up to 11% of the linewidth in the measurable
resonances of the considered isotopes, if interference between resonances is neglected.
The inclusion of relativity decreases the cross section by 35%, mainly due to
the complete retardation form of the electric dipole multipole. However, the contribution
of the next higher multipoles (e.g., magnetic quadrupole) to the cross section
is negligible. This makes the contribution of relativity and higher-order multipoles
to the quantum interference induced shifts a minor effect, even for heavy-Z elements.

text: 'We present an efficient algorithm for a problem in the interface between
clustering and graph embeddings. An embedding '' : G ! M of a graph G into a 2manifold
M maps the vertices in V (G) to distinct points and the edges in E(G) to interior-disjoint
Jordan arcs between the corresponding vertices. In applications in clustering,
cartography, and visualization, nearby vertices and edges are often bundled to
a common node or arc, due to data compression or low resolution. This raises the
computational problem of deciding whether a given map '' : G ! M comes from an
embedding. A map '' : G ! M is a weak embedding if it can be perturbed into an
embedding ψ: G ! M with k'' "k < " for every " > 0. A polynomial-time
algorithm for recognizing weak embeddings was recently found by Fulek and Kyncl
[14], which reduces to solving a system of linear equations over Z2. It runs in
O(n2!) O(n4:75) time, where 2:373 is the matrix multiplication exponent and n
is the number of vertices and edges of G. We improve the running time to O(n log
n). Our algorithm is also conceptually simpler than [14]: We perform a sequence
of local operations that gradually "untangles" the image ''(G) into
an embedding (G), or reports that '' is not a weak embedding. It generalizes a
recent technique developed for the case that G is a cycle and the embedding is
a simple polygon [1], and combines local constraints on the orientation of subgraphs
directly, thereby eliminating the need for solving large systems of linear equations.'

text: We present an approach to interacting quantum many-body systems based on the
notion of quantum groups, also known as q-deformed Lie algebras. In particular,
we show that, if the symmetry of a free quantum particle corresponds to a Lie
group G, in the presence of a many-body environment this particle can be described
by a deformed group, Gq. Crucially, the single deformation parameter, q, contains
all the information about the many-particle interactions in the system. We exemplify
our approach by considering a quantum rotor interacting with a bath of bosons,
and demonstrate that extracting the value of q from closed-form solutions in the
perturbative regime allows one to predict the behavior of the system for arbitrary
values of the impurity-bath coupling strength, in good agreement with nonperturbative
calculations. Furthermore, the value of the deformation parameter allows one to
predict at which coupling strengths rotor-bath interactions result in a formation
of a stable quasiparticle. The approach based on quantum groups does not only
allow for a drastic simplification of impurity problems, but also provides valuable
insights into hidden symmetries of interacting many-particle systems.

text: Using the geodesic distance on the n-dimensional sphere, we study the expected
radius function of the Delaunay mosaic of a random set of points. Specifically,
we consider the partition of the mosaic into intervals of the radius function
and determine the expected number of intervals whose radii are less than or equal
to a given threshold. We find that the expectations are essentially the same as
for the Poisson–Delaunay mosaic in n-dimensional Euclidean space. Assuming the
points are not contained in a hemisphere, the Delaunay mosaic is isomorphic to
the boundary complex of the convex hull in Rn+1, so we also get the expected number
of faces of a random inscribed polytope. As proved in Antonelli et al. [Adv. in
Appl. Probab. 9–12 (1977–1980)], an orthant section of the n-sphere is isometric
to the standard n-simplex equipped with the Fisher information metric. It follows
that the latter space has similar stochastic properties as the n-dimensional Euclidean
space. Our results are therefore relevant in information geometry and in population
genetics.

text: The phytohormone auxin is the information carrier in a plethora of developmental
and physiological processes in plants(1). It has been firmly established that
canonical, nuclear auxin signalling acts through regulation of gene transcription(2).
Here, we combined microfluidics, live imaging, genetic engineering and computational
modelling to reanalyse the classical case of root growth inhibition(3) by auxin.
We show that Arabidopsis roots react to addition and removal of auxin by extremely
rapid adaptation of growth rate. This process requires intracellular auxin perception
but not transcriptional reprogramming. The formation of the canonical TIR1/AFB-Aux/IAA
co-receptor complex is required for the growth regulation, hinting to a novel,
non-transcriptional branch of this signalling pathway. Our results challenge the
current understanding of root growth regulation by auxin and suggest another,
presumably non-transcriptional, signalling output of the canonical auxin pathway.

text: The intercellular transport of auxin is driven by PIN-formed (PIN) auxin efflux
carriers. PINs are localized at the plasma membrane (PM) and on constitutively
recycling endomembrane vesicles. Therefore, PINs can mediate auxin transport either
by direct translocation across the PM or by pumping auxin into secretory vesicles
(SVs), leading to its secretory release upon fusion with the PM. Which of these
two mechanisms dominates is a matter of debate. Here, we addressed the issue with
a mathematical modeling approach. We demonstrate that the efficiency of secretory
transport depends on SV size, half-life of PINs on the PM, pH, exocytosis frequency
and PIN density. 3D structured illumination microscopy (SIM) was used to determine
PIN density on the PM. Combining this data with published values of the other
parameters, we show that the transport activity of PINs in SVs would have to be
at least 1000× greater than on the PM in order to produce a comparable macroscopic
auxin transport. If both transport mechanisms operated simultaneously and PINs
were equally active on SVs and PM, the contribution of secretion to the total
auxin flux would be negligible. In conclusion, while secretory vesicle-mediated
transport of auxin is an intriguing and theoretically possible model, it is unlikely
to be a major mechanism of auxin transport inplanta.

text: We study how a block of genome with a large number of weakly selected loci
introgresses under directional selection into a genetically homogeneous population.
We derive exact expressions for the expected rate of growth of any fragment of
the introduced block during the initial phase of introgression, and show that
the growth rate of a single-locus variant is largely insensitive to its own additive
effect, but depends instead on the combined effect of all loci within a characteristic
linkage scale. The expected growth rate of a fragment is highly correlated with
its long-term introgression probability in populations of moderate size, and can
hence identify variants that are likely to introgress across replicate populations.
We clarify how the introgression probability of an individual variant is determined
by the interplay between hitchhiking with relatively large fragments during the
early phase of introgression and selection on fine-scale variation within these,
which at longer times results in differential introgression probabilities for
beneficial and deleterious loci within successful fragments. By simulating individuals,
we also investigate how introgression probabilities at individual loci depend
on the variance of fitness effects, the net fitness of the introduced block, and
the size of the recipient population, and how this shapes the net advance under
selection. Our work suggests that even highly replicable substitutions may be
associated with a range of selective effects, which makes it challenging to fine
map the causal loci that underlie polygenic adaptation.

text: We analyze the theoretical derivation of the beyond-mean-field equation of
state for two-dimensional gas of dilute, ultracold alkali-metal atoms in the Bardeen–Cooper–Schrieffer
(BCS) to Bose–Einstein condensate (BEC) crossover. We show that at zero temperature
our theory — considering Gaussian fluctuations on top of the mean-field equation
of state — is in very good agreement with experimental data. Subsequently, we
investigate the superfluid density at finite temperature and its renormalization
due to the proliferation of vortex–antivortex pairs. By doing so, we determine
the Berezinskii–Kosterlitz–Thouless (BKT) critical temperature — at which the
renormalized superfluid density jumps to zero — as a function of the inter-atomic
potential strength. We find that the Nelson–Kosterlitz criterion overestimates
the BKT temperature with respect to the renormalization group equations, this
effect being particularly relevant in the intermediate regime of the crossover.

text: 'Genomes of closely-related species or populations often display localized
regions of enhanced relative sequence divergence, termed genomic islands. It has
been proposed that these islands arise through selective sweeps and/or barriers
to gene flow. Here, we genetically dissect a genomic island that controls flower
color pattern differences between two subspecies of Antirrhinum majus, A.m.striatum
and A.m.pseudomajus, and relate it to clinal variation across a natural hybrid
zone. We show that selective sweeps likely raised relative divergence at two tightly-linked
MYB-like transcription factors, leading to distinct flower patterns in the two
subspecies. The two patterns provide alternate floral guides and create a strong
barrier to gene flow where populations come into contact. This barrier affects
the selected flower color genes and tightlylinked loci, but does not extend outside
of this domain, allowing gene flow to lower relative divergence for the rest of
the chromosome. Thus, both selective sweeps and barriers to gene flow play a role
in shaping genomic islands: sweeps cause elevation in relative divergence, while
heterogeneous gene flow flattens the surrounding "sea," making the island of divergence
stand out. By showing how selective sweeps establish alternative adaptive phenotypes
that lead to barriers to gene flow, our study sheds light on possible mechanisms
leading to reproductive isolation and speciation.'

text: There is currently significant interest in operating devices in the quantum
regime, where their behaviour cannot be explained through classical mechanics.
Quantum states, including entangled states, are fragile and easily disturbed by
excessive thermal noise. Here we address the question of whether it is possible
to create non-reciprocal devices that encourage the flow of thermal noise towards
or away from a particular quantum device in a network. Our work makes use of the
cascaded systems formalism to answer this question in the affirmative, showing
how a three-port device can be used as an effective thermal transistor, and illustrates
how this formalism maps onto an experimentally-realisable optomechanical system.
Our results pave the way to more resilient quantum devices and to the use of thermal
noise as a resource.

text: 'Cuprate superconductors have long been thought of as having strong electronic
correlations but negligible spin-orbit coupling. Using spin- and angle-resolved
photoemission spectroscopy, we discovered that one of the most studied cuprate
superconductors, Bi2212, has a nontrivial spin texture with a spin-momentum locking
that circles the Brillouin zone center and a spin-layer locking that allows states
of opposite spin to be localized in different parts of the unit cell. Our findings
pose challenges for the vast majority of models of cuprates, such as the Hubbard
model and its variants, where spin-orbit interaction has been mostly neglected,
and open the intriguing question of how the high-temperature superconducting state
emerges in the presence of this nontrivial spin texture. '
