text: 'The angiosperm seed is composed of three genetically distinct tissues: the
diploid embryo that originates from the fertilized egg cell, the triploid endosperm
that is produced from the fertilized central cell, and the maternal sporophytic
integuments that develop into the seed coat1. At the onset of embryo development
in Arabidopsis thaliana, the zygote divides asymmetrically, producing a small
apical embryonic cell and a larger basal cell that connects the embryo to the
maternal tissue2. The coordinated and synchronous development of the embryo and
the surrounding integuments, and the alignment of their growth axes, suggest communication
between maternal tissues and the embryo. In contrast to animals, however, where
a network of maternal factors that direct embryo patterning have been identified3,4,
only a few maternal mutations have been described to affect embryo development
in plants5–7. Early embryo patterning in Arabidopsis requires accumulation of
the phytohormone auxin in the apical cell by directed transport from the suspensor8–10.
However, the origin of this auxin has remained obscure. Here we investigate the
source of auxin for early embryogenesis and provide evidence that the mother plant
coordinates seed development by supplying auxin to the early embryo from the integuments
of the ovule. We show that auxin response increases in ovules after fertilization,
due to upregulated auxin biosynthesis in the integuments, and this maternally
produced auxin is required for correct embryo development.'

text: L-type Ca2+ channels (LTCCs) play a crucial role in excitation-contraction
coupling and release of hormones from secretory cells. They are targets of antihypertensive
and antiarrhythmic drugs such as diltiazem. Here, we present a photoswitchable
diltiazem, FHU-779, which can be used to reversibly block endogenous LTCCs by
light. FHU-779 is as potent as diltiazem and can be used to place pancreatic β-cell
function and cardiac activity under optical control.

text: We report quantitative evidence of mixing-layer elastic instability in a viscoelastic
fluid flow between two widely spaced obstacles hindering a channel flow at Re
1 and Wi 1. Two mixing layers with nonuniform shear velocity profiles are formed
in the region between the obstacles. The mixing-layer instability arises in the
vicinity of an inflection point on the shear velocity profile with a steep variation
in the elastic stress. The instability results in an intermittent appearance of
small vortices in the mixing layers and an amplification of spatiotemporal averaged
vorticity in the elastic turbulence regime. The latter is characterized through
scaling of friction factor with Wi and both pressure and velocity spectra. Furthermore,
the observations reported provide improved understanding of the stability of the
mixing layer in a viscoelastic fluid at large elasticity, i.e., Wi 1 and Re 1
and oppose the current view of suppression of vorticity solely by polymer additives.

text: We present layered concurrent programs, a compact and expressive notation
for specifying refinement proofs of concurrent programs. A layered concurrent
program specifies a sequence of connected concurrent programs, from most concrete
to most abstract, such that common parts of different programs are written exactly
once. These programs are expressed in the ordinary syntax of imperative concurrent
programs using gated atomic actions, sequencing, choice, and (recursive) procedure
calls. Each concurrent program is automatically extracted from the layered program.
We reduce refinement to the safety of a sequence of concurrent checker programs,
one each to justify the connection between every two consecutive concurrent programs.
These checker programs are also automatically extracted from the layered program.
Layered concurrent programs have been implemented in the CIVL verifier which has
been successfully used for the verification of several complex concurrent programs.

text: 'Which properties of metabolic networks can be derived solely from stoichiometry?
Predictive results have been obtained by flux balance analysis (FBA), by postulating
that cells set metabolic fluxes to maximize growth rate. Here we consider a generalization
of FBA to single-cell level using maximum entropy modeling, which we extend and
test experimentally. Specifically, we define for Escherichia coli metabolism a
flux distribution that yields the experimental growth rate: the model, containing
FBA as a limit, provides a better match to measured fluxes and it makes a wide
range of predictions: on flux variability, regulation, and correlations; on the
relative importance of stoichiometry vs. optimization; on scaling relations for
growth rate distributions. We validate the latter here with single-cell data at
different sub-inhibitory antibiotic concentrations. The model quantifies growth
optimization as emerging from the interplay of competitive dynamics in the population
and regulation of metabolism at the level of single cells.'

text: 'XY systems usually show chromosome-wide compensation of X-linked genes, while
in many ZW systems, compensation is restricted to a minority of dosage-sensitive
genes. Why such differences arose is still unclear. Here, we combine comparative
genomics, transcriptomics and proteomics to obtain a complete overview of the
evolution of gene dosage on the Z-chromosome of Schistosoma parasites. We compare
the Z-chromosome gene content of African (Schistosoma mansoni and S. haematobium)
and Asian (S. japonicum) schistosomes and describe lineage-specific evolutionary
strata. We use these to assess gene expression evolution following sex-linkage.
The resulting patterns suggest a reduction in expression of Z-linked genes in
females, combined with upregulation of the Z in both sexes, in line with the first
step of Ohno’s classic model of dosage compensation evolution. Quantitative proteomics
suggest that post-transcriptional mechanisms do not play a major role in balancing
the expression of Z-linked genes. '

text: Pancreas development involves a coordinated process in which an early phase
of cell segregation is followed by a longer phase of lineage restriction, expansion,
and tissue remodeling. By combining clonal tracing and whole-mount reconstruction
with proliferation kinetics and single-cell transcriptional profiling, we define
the functional basis of pancreas morphogenesis. We show that the large-scale organization
of mouse pancreas can be traced to the activity of self-renewing precursors positioned
at the termini of growing ducts, which act collectively to drive serial rounds
of stochastic ductal bifurcation balanced by termination. During this phase of
branching morphogenesis, multipotent precursors become progressively fate-restricted,
giving rise to self-renewing acinar-committed precursors that are conveyed with
growing ducts, as well as ductal progenitors that expand the trailing ducts and
give rise to delaminating endocrine cells. These findings define quantitatively
how the functional behavior and lineage progression of precursor pools determine
the large-scale patterning of pancreatic sub-compartments.

text: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent computation threads. We present synchronization,
a new proof rule that simplifies the verification of asynchronous programs by
introducing the fiction, for proof purposes, that asynchronous operations complete
synchronously. Synchronization summarizes an asynchronous computation as immediate
atomic effect. Modular verification is enabled via pending asynchronous calls
in atomic summaries, and a complementary proof rule that eliminates pending asynchronous
calls when components and their specifications are composed. We evaluate synchronization
in the context of a multi-layer refinement verification methodology on a collection

text: "The current state of the art in real-time two-dimensional water wave simulation
requires developers to choose between efficient Fourier-based methods, which lack
interactions with moving obstacles, and finite-difference or finite element methods,
which handle environmental interactions but are significantly more expensive.
This paper attempts to bridge this long-standing gap between complexity and performance,
by proposing a new wave simulation method that can faithfully simulate wave interactions
with moving obstacles in real time while simultaneously preserving minute details
and accommodating very large simulation domains.\r\n\r\nPrevious methods for simulating
2D water waves directly compute the change in height of the water surface, a strategy
which imposes limitations based on the CFL condition (fast moving waves require
small time steps) and Nyquist's limit (small wave details require closely-spaced
simulation variables). This paper proposes a novel wavelet transformation that
discretizes the liquid motion in terms of amplitude-like functions that vary over
space, frequency, and direction, effectively generalizing Fourier-based methods
to handle local interactions. Because these new variables change much more slowly
over space than the original water height function, our change of variables drastically
reduces the limitations of the CFL condition and Nyquist limit, allowing us to
simulate highly detailed water waves at very large visual resolutions. Our discretization
is amenable to fast summation and easy to parallelize. We also present basic extensions
like pre-computed wave paths and two-way solid fluid coupling. Finally, we argue
that our discretization provides a convenient set of variables for artistic manipulation,
which we illustrate with a novel wave-painting interface."

text: The Fluid Implicit Particle method (FLIP) reduces numerical dissipation by
combining particles with grids. To improve performance, the subsequent narrow
band FLIP method (NB‐FLIP) uses a FLIP‐based fluid simulation only near the liquid
surface and a traditional grid‐based fluid simulation away from the surface. This
spatially‐limited FLIP simulation significantly reduces the number of particles
and alleviates a computational bottleneck. In this paper, we extend the NB‐FLIP
idea even further, by allowing a simulation to transition between a FLIP‐like
fluid simulation and a grid‐based simulation in arbitrary locations, not just
near the surface. This approach leads to even more savings in memory and computation,
because we can concentrate the particles only in areas where they are needed.
More importantly, this new method allows us to seamlessly transition to smooth
implicit surface geometry wherever the particle‐based simulation is unnecessary.
Consequently, our method leads to a practical algorithm for avoiding the noisy
surface artifacts associated with particle‐based liquid simulations, while simultaneously
maintaining the benefits of a FLIP simulation in regions of dynamic motion.

text: Recent studies suggest that unstable, nonchaotic solutions of the Navier-Stokes
equation may provide deep insights into fluid turbulence. In this article, we
present a combined experimental and numerical study exploring the dynamical role
of unstable equilibrium solutions and their invariant manifolds in a weakly turbulent,
electromagnetically driven, shallow fluid layer. Identifying instants when turbulent
evolution slows down, we compute 31 unstable equilibria of a realistic two-dimensional
model of the flow. We establish the dynamical relevance of these unstable equilibria
by showing that they are closely visited by the turbulent flow. We also establish
the dynamical relevance of unstable manifolds by verifying that they are shadowed
by turbulent trajectories departing from the neighborhoods of unstable equilibria
over large distances in state space.

text: Fluorescent sensors are an essential part of the experimental toolbox of the
life sciences, where they are used ubiquitously to visualize intra- and extracellular
signaling. In the brain, optical neurotransmitter sensors can shed light on temporal
and spatial aspects of signal transmission by directly observing, for instance,
neurotransmitter release and spread. Here we report the development and application
of the first optical sensor for the amino acid glycine, which is both an inhibitory
neurotransmitter and a co-agonist of the N-methyl-d-aspartate receptors (NMDARs)
involved in synaptic plasticity. Computational design of a glycine-specific binding
protein allowed us to produce the optical glycine FRET sensor (GlyFS), which can
be used with single and two-photon excitation fluorescence microscopy. We took
advantage of this newly developed sensor to test predictions about the uneven
spatial distribution of glycine in extracellular space and to demonstrate that
extracellular glycine levels are controlled by plasticity-inducing stimuli.

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: 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: Reachability analysis is difficult for hybrid automata with affine differential
equations, because the reach set needs to be approximated. Promising abstraction
techniques usually employ interval methods or template polyhedra. Interval methods
account for dense time and guarantee soundness, and there are interval-based tools
that overapproximate affine flowpipes. But interval methods impose bounded and
rigid shapes, which make refinement expensive and fixpoint detection difficult.
Template polyhedra, on the other hand, can be adapted flexibly and can be unbounded,
but sound template refinement for unbounded reachability analysis has been implemented
only for systems with piecewise constant dynamics. We capitalize on the advantages
of both techniques, combining interval arithmetic and template polyhedra, using
the former to abstract time and the latter to abstract space. During a CEGAR loop,
whenever a spurious error trajectory is found, we compute additional space constraints
and split time intervals, and use these space-time interpolants to eliminate the
counterexample. Space-time interpolation offers a lazy, flexible framework for
increasing precision while guaranteeing soundness, both for error avoidance and
fixpoint detection. To the best of out knowledge, this is the first abstraction
refinement scheme for the reachability analysis over unbounded and dense time
of affine hybrid systems, which is both sound and automatic. We demonstrate the
effectiveness of our algorithm with several benchmark examples, which cannot be
handled by other tools.

text: 'Given a model and a specification, the fundamental model-checking problem
asks for algorithmic verification of whether the model satisfies the specification.
We consider graphs and Markov decision processes (MDPs), which are fundamental
models for reactive systems. One of the very basic specifications that arise in
verification of reactive systems is the strong fairness (aka Streett) objective.
Given different types of requests and corresponding grants, the objective requires
that for each type, if the request event happens infinitely often, then the corresponding
grant event must also happen infinitely often. All ω -regular objectives can be
expressed as Streett objectives and hence they are canonical in verification.
To handle the state-space explosion, symbolic algorithms are required that operate
on a succinct implicit representation of the system rather than explicitly accessing
the system. While explicit algorithms for graphs and MDPs with Streett objectives
have been widely studied, there has been no improvement of the basic symbolic
algorithms. The worst-case numbers of symbolic steps required for the basic symbolic
algorithms are as follows: quadratic for graphs and cubic for MDPs. In this work
we present the first sub-quadratic symbolic algorithm for graphs with Streett
objectives, and our algorithm is sub-quadratic even for MDPs. Based on our algorithmic
insights we present an implementation of the new symbolic approach and show that
it improves the existing approach on several academic benchmark examples.'

text: "High-dimensional time series are common in many domains. Since human\r\ncognition
is not optimized to work well in high-dimensional spaces, these areas\r\ncould
benefit from interpretable low-dimensional representations. However, most\r\nrepresentation
learning algorithms for time series data are difficult to\r\ninterpret. This is
due to non-intuitive mappings from data features to salient\r\nproperties of the
representation and non-smoothness over time. To address this\r\nproblem, we propose
a new representation learning framework building on ideas\r\nfrom interpretable
discrete dimensionality reduction and deep generative\r\nmodeling. This framework
allows us to learn discrete representations of time\r\nseries, which give rise
to smooth and interpretable embeddings with superior\r\nclustering performance.
We introduce a new way to overcome the\r\nnon-differentiability in discrete representation
learning and present a\r\ngradient-based version of the traditional self-organizing
map algorithm that is\r\nmore performant than the original. Furthermore, to allow
for a probabilistic\r\ninterpretation of our method, we integrate a Markov model
in the representation\r\nspace. This model uncovers the temporal transition structure,
improves\r\nclustering performance even further and provides additional explanatory\r\ninsights
as well as a natural representation of uncertainty. We evaluate our\r\nmodel in
terms of clustering performance and interpretability on static\r\n(Fashion-)MNIST
data, a time series of linearly interpolated (Fashion-)MNIST\r\nimages, a chaotic
Lorenz attractor system with two macro states, as well as on\r\na challenging
real world medical time series application on the eICU data set.\r\nOur learned
representations compare favorably with competitor methods and\r\nfacilitate downstream
tasks on the real world data."

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.
