text: 'Genome-scale diversity data are increasingly available in a variety of biological
systems, and can be used to reconstruct the past evolutionary history of species
divergence. However, extracting the full demographic information from these data
is not trivial, and requires inferential methods that account for the diversity
of coalescent histories throughout the genome. Here, we evaluate the potential
and limitations of one such approach. We reexamine a well-known system of mussel
sister species, using the joint site frequency spectrum (jSFS) of synonymousmutations
computed either fromexome capture or RNA-seq, in an Approximate Bayesian Computation
(ABC) framework. We first assess the best sampling strategy (number of: individuals,
loci, and bins in the jSFS), and show that model selection is robust to variation
in the number of individuals and loci. In contrast, different binning choices
when summarizing the jSFS, strongly affect the results: including classes of low
and high frequency shared polymorphisms can more effectively reveal recent migration
events. We then take advantage of the flexibility of ABC to compare more realistic
models of speciation, including variation in migration rates through time (i.e.,
periodic connectivity) and across genes (i.e., genome-wide heterogeneity in migration
rates). We show that these models were consistently selected as the most probable,
suggesting that mussels have experienced a complex history of gene flow during
divergence and that the species boundary is semi-permeable. Our work provides
a comprehensive evaluation of ABC demographic inference in mussels based on the
coding jSFS, and supplies guidelines for employing different sequencing techniques
and sampling strategies. We emphasize, perhaps surprisingly, that inferences are
less limited by the volume of data, than by the way in which they are analyzed.'

text: Secondary contact is the reestablishment of gene flow between sister populations
that have diverged. For instance, at the end of the Quaternary glaciations in
Europe, secondary contact occurred during the northward expansion of the populations
which had found refugia in the southern peninsulas. With the advent of multi-locus
markers, secondary contact can be investigated using various molecular signatures
including gradients of allele frequency, admixture clines, and local increase
of genetic differentiation. We use coalescent simulations to investigate if molecular
data provide enough information to distinguish between secondary contact following
range expansion and an alternative evolutionary scenario consisting of a barrier
to gene flow in an isolation-by-distance model. We find that an excess of linkage
disequilibrium and of genetic diversity at the suture zone is a unique signature
of secondary contact. We also find that the directionality index ψ, which was
proposed to study range expansion, is informative to distinguish between the two
hypotheses. However, although evidence for secondary contact is usually conveyed
by statistics related to admixture coefficients, we find that they can be confounded
by isolation-by-distance. We recommend to account for the spatial repartition
of individuals when investigating secondary contact in order to better reflect
the complex spatio-temporal evolution of populations and species.

text: Cell polarity, manifested by the localization of proteins to distinct polar
plasma membrane domains, is a key prerequisite of multicellular life. In plants,
PIN auxin transporters are prominent polarity markers crucial for a plethora of
developmental processes. Cell polarity mechanisms in plants are distinct from
other eukaryotes and still largely elusive. In particular, how the cell polarities
are propagated and maintained following cell division remains unknown. Plant cytokinesis
is orchestrated by the cell plate—a transient centrifugally growing endomembrane
compartment ultimately forming the cross wall1. Trafficking of polar membrane
proteins is typically redirected to the cell plate, and these will consequently
have opposite polarity in at least one of the daughter cells2–5. Here, we provide
mechanistic insights into post-cytokinetic re-establishment of cell polarity as
manifested by the apical, polar localization of PIN2. We show that the apical
domain is defined in a cell-intrinsic manner and that re-establishment of PIN2
localization to this domain requires de novo protein secretion and endocytosis,
but not basal-to-apical transcytosis. Furthermore, we identify a PINOID-related
kinase WAG1, which phosphorylates PIN2 in vitro6 and is transcriptionally upregulated
specifically in dividing cells, as a crucial regulator of post-cytokinetic PIN2
polarity re-establishment.

text: We consider a class of students learning a language from a teacher. The situation
can be interpreted as a group of child learners receiving input from the linguistic
environment. The teacher provides sample sentences. The students try to learn
the grammar from the teacher. In addition to just listening to the teacher, the
students can also communicate with each other. The students hold hypotheses about
the grammar and change them if they receive counter evidence. The process stops
when all students have converged to the correct grammar. We study how the time
to convergence depends on the structure of the classroom by introducing and evaluating
various complexity measures. We find that structured communication between students,
although potentially introducing confusion, can greatly reduce some of the complexity
measures. Our theory can also be interpreted as applying to the scientific process,
where nature is the teacher and the scientists are the students.

text: The emergence of syntax during childhood is a remarkable example of how complex
correlations unfold in nonlinear ways through development. In particular, rapid
transitions seem to occur as children reach the age of two, which seems to separate
a two-word, tree-like network of syntactic relations among words from the scale-free
graphs associated with the adult, complex grammar. Here, we explore the evolution
of syntax networks through language acquisition using the chromatic number, which
captures the transition and provides a natural link to standard theories on syntactic
structures. The data analysis is compared to a null model of network growth dynamics
which is shown to display non-trivial and sensible differences. At a more general
level, we observe that the chromatic classes define independent regions of the
graph, and thus, can be interpreted as the footprints of incompatibility relations,
somewhat as opposed to modularity considerations.

text: "We study the unique solution $m$ of the Dyson equation \\[ -m(z)^{-1} = z
- a\r\n+ S[m(z)] \\] on a von Neumann algebra $\\mathcal{A}$ with the constraint\r\n$\\mathrm{Im}\\,m\\geq
0$. Here, $z$ lies in the complex upper half-plane, $a$ is\r\na self-adjoint element
of $\\mathcal{A}$ and $S$ is a positivity-preserving\r\nlinear operator on $\\mathcal{A}$.
We show that $m$ is the Stieltjes transform\r\nof a compactly supported $\\mathcal{A}$-valued
measure on $\\mathbb{R}$. Under\r\nsuitable assumptions, we establish that this
measure has a uniformly\r\n$1/3$-H\\\"{o}lder continuous density with respect
to the Lebesgue measure, which\r\nis supported on finitely many intervals, called
bands. In fact, the density is\r\nanalytic inside the bands with a square-root
growth at the edges and internal\r\ncubic root cusps whenever the gap between
two bands vanishes. The shape of\r\nthese singularities is universal and no other
singularity may occur. We give a\r\nprecise asymptotic description of $m$ near
the singular points. These\r\nasymptotics generalize the analysis at the regular
edges given in the companion\r\npaper on the Tracy-Widom universality for the
edge eigenvalue statistics for\r\ncorrelated random matrices [arXiv:1804.07744]
and they play a key role in the\r\nproof of the Pearcey universality at the cusp
for Wigner-type matrices\r\n[arXiv:1809.03971,arXiv:1811.04055]. We also extend
the finite dimensional band\r\nmass formula from [arXiv:1804.07744] to the von
Neumann algebra setting by\r\nshowing that the spectral mass of the bands is topologically
rigid under\r\ndeformations and we conclude that these masses are quantized in
some important\r\ncases."

text: 'We investigate the free boundary Schur process, a variant of the Schur process
introduced by Okounkov and Reshetikhin, where we allow the first and the last
partitions to be arbitrary (instead of empty in the original setting). The pfaffian
Schur process, previously studied by several authors, is recovered when just one
of the boundary partitions is left free. We compute the correlation functions
of the process in all generality via the free fermion formalism, which we extend
with the thorough treatment of “free boundary states.” For the case of one free
boundary, our approach yields a new proof that the process is pfaffian. For the
case of two free boundaries, we find that the process is not pfaffian, but a closely
related process is. We also study three different applications of the Schur process
with one free boundary: fluctuations of symmetrized last passage percolation models,
limit shapes and processes for symmetric plane partitions and for plane overpartitions.'

text: 'Retina is a paradigmatic system for studying sensory encoding: the transformation
of light into spiking activity of ganglion cells. The inverse problem, where stimulus
is reconstructed from spikes, has received less attention, especially for complex
stimuli that should be reconstructed “pixel-by-pixel”. We recorded around a hundred
neurons from a dense patch in a rat retina and decoded movies of multiple small
randomly-moving discs. We constructed nonlinear (kernelized and neural network)
decoders that improved significantly over linear results. An important contribution
to this was the ability of nonlinear decoders to reliably separate between neural
responses driven by locally fluctuating light signals, and responses at locally
constant light driven by spontaneous-like activity. This improvement crucially
depended on the precise, non-Poisson temporal structure of individual spike trains,
which originated in the spike-history dependence of neural responses. We propose
a general principle by which downstream circuitry could discriminate between spontaneous
and stimulus-driven activity based solely on higher-order statistical structure
in the incoming spike trains.'
