text: Size control is a fundamental question in biology, showing incremental complexity
in plants, whose cells possess a rigid cell wall. The phytohormone auxin is a
vital growth regulator with central importance for differential growth control.
Our results indicate that auxin-reliant growth programs affect the molecular complexity
of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent
induction and repression of growth coincide with reduced and enhanced molecular
complexity of xyloglucans, respectively. In agreement with a proposed function
in growth control, genetic interference with xyloglucan side decorations distinctly
modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent
growth programs have a spatially defined effect on xyloglucan’s molecular structure,
which in turn affects cell wall mechanics and specifies differential, gravitropic
hypocotyl growth.

text: We define quantum equivariant K-theory of Nakajima quiver varieties. We discuss
type A in detail as well as its connections with quantum XXZ spin chains and trigonometric
Ruijsenaars-Schneider models. Finally we study a limit which produces a K-theoretic
version of results of Givental and Kim, connecting quantum geometry of flag varieties
and Toda lattice.
acknowledgement: 'First of all we would like to thank Andrei Okounkov for invaluable
discussions, advises and sharing with us his fantastic viewpoint on modern quantum
geometry. We are also grateful to D. Korb and Z. Zhou for their interest and comments.

text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

text: Genomes of germ cells present an existential vulnerability to organisms because
germ cell mutations will propagate to future generations. Transposable elements
are one source of such mutations. In the small flowering plant Arabidopsis, Long
et al. found that genome methylation in the male germline is directed by small
interfering RNAs (siRNAs) imperfectly transcribed from transposons (see the Perspective
by Mosher). These germline siRNAs silence germline transposons and establish inherited
methylation patterns in sperm, thus maintaining the integrity of the plant genome
across generations.

diversity of neuronal types. Nonetheless, a cardinal feature of mammalian brain
neurogenesis is thought to be that excitatory and inhibitory neurons derive from
separate, spatially segregated progenitors. Whether bi-potential progenitors with
an intrinsic capacity to generate both lineages exist and how such a fate decision
may be regulated are unknown. Using cerebellar development as a model, we discover
that individual progenitors can give rise to both inhibitory and excitatory lineages.
Gradations of Notch activity determine the fates of the progenitors and their
daughters. Daughters with the highest levels of Notch activity retain the progenitor
fate, while intermediate levels of Notch activity generate inhibitory neurons,
and daughters with very low levels of Notch signaling adopt the excitatory fate.
Therefore, Notch-mediated binary cell fate choice is a mechanism for regulating
the ratio of excitatory to inhibitory neurons from common progenitors.

text: Zygotic genome activation (ZGA) initiates regionalized transcription underlying
distinct cellular identities. ZGA is dependent upon dynamic chromatin architecture
sculpted by conserved DNA-binding proteins. However, the direct mechanistic link
between the onset of ZGA and the tissue-specific transcription remains unclear.
Here, we have addressed the involvement of chromatin organizer Satb2 in orchestrating
both processes during zebrafish embryogenesis. Integrative analysis of transcriptome,
genome-wide occupancy and chromatin accessibility reveals contrasting molecular
activities of maternally deposited and zygotically synthesized Satb2. Maternal
Satb2 prevents premature transcription of zygotic genes by influencing the interplay
between the pluripotency factors. By contrast, zygotic Satb2 activates transcription
of the same group of genes during neural crest development and organogenesis.
Thus, our comparative analysis of maternal versus zygotic function of Satb2 underscores
how these antithetical activities are temporally coordinated and functionally
implemented highlighting the evolutionary implications of the biphasic and bimodal
regulation of landmark developmental transitions by a single determinant.

text: 'In mammalian genomes, differentially methylated regions (DMRs) and histone
marks including trimethylation of histone 3 lysine 27 (H3K27me3) at imprinted
genes are asymmetrically inherited to control parentally-biased gene expression.
However, neither parent-of-origin-specific transcription nor imprints have been
comprehensively mapped at the blastocyst stage of preimplantation development.
Here, we address this by integrating transcriptomic and epigenomic approaches
in mouse preimplantation embryos. We find that seventy-one genes exhibit previously
unreported parent-of-origin-specific expression in blastocysts (nBiX: novel blastocyst-imprinted
expressed). Uniparental expression of nBiX genes disappears soon after implantation.
Micro-whole-genome bisulfite sequencing (µWGBS) of individual uniparental blastocysts
detects 859 DMRs. We further find that 16% of nBiX genes are associated with a
DMR, whereas most are associated with parentally-biased H3K27me3, suggesting a
role for Polycomb-mediated imprinting in blastocysts. nBiX genes are clustered:
five clusters contained at least one published imprinted gene, and five clusters
exclusively contained nBiX genes. These data suggest that early development undergoes
a complex program of stage-specific imprinting involving different tiers of regulation.'

text: 'The important roles of mitochondrial function and dysfunction in the process
of neurodegeneration are widely acknowledged. Retinal ganglion cells (RGCs) appear
to be a highly vulnerable neuronal cell type in the central nervous system with
respect to mitochondrial dysfunction but the actual reasons for this are still
incompletely understood. These cells have a unique circumstance where unmyelinated
axons must bend nearly 90° to exit the eye and then cross a translaminar pressure
gradient before becoming myelinated in the optic nerve. This region, the optic
nerve head, contains some of the highest density of mitochondria present in these
cells. Glaucoma represents a perfect storm of events occurring at this location,
with a combination of changes in the translaminar pressure gradient and reassignment
of the metabolic support functions of supporting glia, which appears to apply
increased metabolic stress to the RGC axons leading to a failure of axonal transport
mechanisms. However, RGCs themselves are also extremely sensitive to genetic mutations,
particularly in genes affecting mitochondrial dynamics and mitochondrial clearance.
These mutations, which systemically affect the mitochondria in every cell, often
lead to an optic neuropathy as the sole pathologic defect in affected patients.
This review summarizes knowledge of mitochondrial structure and function, the
known energy demands of neurons in general, and places these in the context of
normal and pathological characteristics of mitochondria attributed to RGCs. '

text: 'Auxin is a key regulator of plant growth and development. Local auxin biosynthesis
and intercellular transport generates regional gradients in the root that are
instructive for processes such as specification of developmental zones that maintain
root growth and tropic responses. Here we present a toolbox to study auxin-mediated
root development that features: (i) the ability to control auxin synthesis with
high spatio-temporal resolution and (ii) single-cell nucleus tracking and morphokinetic
analysis infrastructure. Integration of these two features enables cutting-edge
analysis of root development at single-cell resolution based on morphokinetic
parameters under normal growth conditions and during cell-type-specific induction
of auxin biosynthesis. We show directional auxin flow in the root and refine the
contributions of key players in this process. In addition, we determine the quantitative
kinetics of Arabidopsis root meristem skewing, which depends on local auxin gradients
but does not require PIN2 and AUX1 auxin transporter activities. Beyond the mechanistic
insights into root development, the tools developed here will enable biologists
to study kinetics and morphology of various critical processes at the single cell-level
in whole organisms.'

text: Heart rate variability (hrv) is a physiological phenomenon of the variation
in the length of the time interval between consecutive heartbeats. In many cases
it could be an indicator of the development of pathological states. The classical
approach to the analysis of hrv includes time domain methods and frequency domain
methods. However, attempts are still being made to define new and more effective
hrv assessment tools. Persistent homology is a novel data analysis tool developed
in the recent decades that is rooted at algebraic topology. The Topological Data
Analysis (TDA) approach focuses on examining the shape of the data in terms of
connectedness and holes, and has recently proved to be very effective in various
fields of research. In this paper we propose the use of persistent homology to
the hrv analysis. We recall selected topological descriptors used in the literature
and we introduce some new topological descriptors that reflect the specificity
of hrv, and we discuss their relation to the standard hrv measures. In particular,
we show that this novel approach provides a collection of indices that might be
at least as useful as the classical parameters in differentiating between series
of beat-to-beat intervals (RR-intervals) in healthy subjects and patients suffering
from a stroke episode.

text: In dense biological tissues, cell types performing different roles remain
segregated by maintaining sharp interfaces. To better understand the mechanisms
for such sharp compartmentalization, we study the effect of an imposed heterotypic
tension at the interface between two distinct cell types in a fully 3D Voronoi
model for confluent tissues. We find that cells rapidly sort and self-organize
to generate a tissue-scale interface between cell types, and cells adjacent to
this interface exhibit signature geometric features including nematic-like ordering,
bimodal facet areas, and registration, or alignment, of cell centers on either
side of the two-tissue interface. The magnitude of these features scales directly
with the magnitude of the imposed tension, suggesting that biologists can estimate
the magnitude of tissue surface tension between two tissue types simply by segmenting
a 3D tissue. To uncover the underlying physical mechanisms driving these geometric
features, we develop two minimal, ordered models using two different underlying
lattices that identify an energetic competition between bulk cell shapes and tissue
interface area. When the interface area dominates, changes to neighbor topology
are costly and occur less frequently, which generates the observed geometric features.

text: Roots are composed of different root types and, in the dicotyledonous Arabidopsis,
typically consist of a primary root that branches into lateral roots. Adventitious
roots emerge from non-root tissue and are formed upon wounding or other types
of abiotic stress. Here, we investigated adventitious root (AR) formation in Arabidopsis
hypocotyls under conditions of altered abscisic acid (ABA) signaling. Exogenously
applied ABA suppressed AR formation at 0.25 µM or higher doses. AR formation was
less sensitive to the synthetic ABA analog pyrabactin (PB). However, PB was a
more potent inhibitor at concentrations above 1 µM, suggesting that it was more
selective in triggering a root inhibition response. Analysis of a series of phosphonamide
and phosphonate pyrabactin analogs suggested that adventitious root formation
and lateral root branching are differentially regulated by ABA signaling. ABA
biosynthesis and signaling mutants affirmed a general inhibitory role of ABA and
point to PYL1 and PYL2 as candidate ABA receptors that regulate AR inhibition.

mutants and ABA signaling mutants.

text: We revise a previous result about the Fröhlich dynamics in the strong coupling
limit obtained in Griesemer (Rev Math Phys 29(10):1750030, 2017). In the latter
it was shown that the Fröhlich time evolution applied to the initial state φ0⊗ξα,
where φ0 is the electron ground state of the Pekar energy functional and ξα the
associated coherent state of the phonons, can be approximated by a global phase
for times small compared to α2. In the present note we prove that a similar approximation
holds for t=O(α2) if one includes a nontrivial effective dynamics for the phonons
that is generated by an operator proportional to α−2 and quadratic in creation
and annihilation operators. Our result implies that the electron ground state
remains close to its initial state for times of order α2, while the phonon fluctuations
around the coherent state ξα can be described by a time-dependent Bogoliubov transformation.

text: 'Organ function depends on tissues adopting the correct architecture. However,
insights into organ architecture are currently hampered by an absence of standardized
quantitative 3D analysis. We aimed to develop a robust technology to visualize,
digitalize, and segment the architecture of two tubular systems in 3D: double
resin casting micro computed tomography (DUCT). As proof of principle, we applied
DUCT to a mouse model for Alagille syndrome (Jag1Ndr/Ndr mice), characterized
by intrahepatic bile duct paucity, that can spontaneously generate a biliary system
in adulthood. DUCT identified increased central biliary branching and peripheral
bile duct tortuosity as two compensatory processes occurring in distinct regions
of Jag1Ndr/Ndr liver, leading to full reconstitution of wild-type biliary volume
and phenotypic recovery. DUCT is thus a powerful new technology for 3D analysis,
which can reveal novel phenotypes and provide a standardized method of defining
liver architecture in mouse models.'

text: Assemblies of actin and its regulators underlie the dynamic morphology of
all eukaryotic cells. To understand how actin regulatory proteins work together
to generate actin-rich structures such as filopodia, we analyzed the localization
of diverse actin regulators within filopodia in Drosophila embryos and in a complementary
in vitro system of filopodia-like structures (FLSs). We found that the composition
of the regulatory protein complex where actin is incorporated (the filopodial
tip complex) is remarkably heterogeneous both in vivo and in vitro. Our data reveal
that different pairs of proteins correlate with each other and with actin bundle
length, suggesting the presence of functional subcomplexes. This is consistent
with a theoretical framework where three or more redundant subcomplexes join the
tip complex stochastically, with any two being sufficient to drive filopodia formation.
We provide an explanation for the observed heterogeneity and suggest that a mechanism
based on multiple components allows stereotypical filopodial dynamics to arise
from diverse upstream signaling pathways.

text: Cryo-EM grid preparation is an important bottleneck in protein structure determination,
especially for membrane proteins, typically requiring screening of a large number
of conditions. We systematically investigated the effects of buffer components,
blotting conditions and grid types on the outcome of grid preparation of five
different membrane protein samples. Aggregation was the most common type of problem
which was addressed by changing detergents, salt concentration or reconstitution
of proteins into nanodiscs or amphipols. We show that the optimal concentration
of detergent is between 0.05 and 0.4% and that the presence of a low concentration
of detergent with a high critical micellar concentration protects the proteins
from denaturation at the air-water interface. Furthermore, we discuss the strategies
for achieving an adequate ice thickness, particle coverage and orientation distribution
on free ice and on support films. Our findings provide a clear roadmap for comprehensive
screening of conditions for cryo-EM grid preparation of membrane proteins.

text: We extend our recent result [22] on the central limit theorem for the linear
eigenvalue statistics of non-Hermitian matrices X with independent, identically
distributed complex entries to the real symmetry class. We find that the expectation
and variance substantially differ from their complex counterparts, reflecting
(i) the special spectral symmetry of real matrices onto the real axis; and (ii)
the fact that real i.i.d. matrices have many real eigenvalues. Our result generalizes
the previously known special cases where either the test function is analytic
[49] or the first four moments of the matrix elements match the real Gaussian
[59, 44]. The key element of the proof is the analysis of several weakly dependent
Dyson Brownian motions (DBMs). The conceptual novelty of the real case compared
with [22] is that the correlation structure of the stochastic differentials in
each individual DBM is non-trivial, potentially even jeopardising its well-posedness.

text: A central goal in systems neuroscience is to understand the functions performed
by neural circuits. Previous top-down models addressed this question by comparing
the behaviour of an ideal model circuit, optimised to perform a given function,
with neural recordings. However, this requires guessing in advance what function
is being performed, which may not be possible for many neural systems. To address
this, we propose an inverse reinforcement learning (RL) framework for inferring
the function performed by a neural network from data. We assume that the responses
of each neuron in a network are optimised so as to drive the network towards ‘rewarded’
states, that are desirable for performing a given function. We then show how one
can use inverse RL to infer the reward function optimised by the network from
observing its responses. This inferred reward function can be used to predict
how the neural network should adapt its dynamics to perform the same function
when the external environment or network structure changes. This could lead to
theoretical predictions about how neural network dynamics adapt to deal with cell
death and/or varying sensory stimulus statistics.

text: 'Humans conceptualize the diversity of life by classifying individuals into
types we call ‘species’1. The species we recognize influence political and financial
decisions and guide our understanding of how units of diversity evolve and interact.
Although the idea of species may seem intuitive, a debate about the best way to
define them has raged even before Darwin2. So much energy has been devoted to
the so-called ‘species problem’ that no amount of discourse will ever likely solve
it2,3. Dozens of species concepts are currently recognized3, but we lack a concrete
understanding of how much researchers actually disagree and the factors that cause
them to think differently1,2. To address this, we used a survey to quantify the
species problem for the first time. The results indicate that the disagreement
is extensive: two randomly chosen respondents will most likely disagree on the
nature of species. The probability of disagreement is not predicted by researcher
experience or broad study system, but tended to be lower among researchers with
similar focus, training and who study the same organism. Should we see this diversity
of perspectives as a problem? We argue that we should not.'

text: The relative motion of three impenetrable particles on a ring, in our case
two identical fermions and one impurity, is isomorphic to a triangular quantum
billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
can be integrable or non-integrable (also referred to in the main text as chaotic).
To set the stage, we first investigate the energy level distributions of the billiards
as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
analyze properties of probability distributions of individual quantum states.
We find that convolutional neural networks can correctly classify integrable and
non-integrable states. The decisive features of the wave functions are the normalization
and a large number of zero elements, corresponding to the existence of a nodal
line. The network achieves typical accuracies of 97%, suggesting that machine
learning tools can be used to analyze and classify the morphology of probability
densities obtained in theory or experiment.
