text: Spatial patterns are ubiquitous on the subcellular, cellular and tissue level,
and can be studied using imaging techniques such as light and fluorescence microscopy.
Imaging data provide quantitative information about biological systems; however,
mechanisms causing spatial patterning often remain elusive. In recent years, spatio-temporal
mathematical modelling has helped to overcome this problem. Yet, outliers and
structured noise limit modelling of whole imaging data, and models often consider
spatial summary statistics. Here, we introduce an integrated data-driven modelling
approach that can cope with measurement artefacts and whole imaging data. Our
approach combines mechanistic models of the biological processes with robust statistical
models of the measurement process. The parameters of the integrated model are
calibrated using a maximum-likelihood approach. We used this integrated modelling
approach to study in vivo gradients of the chemokine (C-C motif) ligand 21 (CCL21).
CCL21 gradients guide dendritic cells and are important in the adaptive immune
response. Using artificial data, we verified that the integrated modelling approach
provides reliable parameter estimates in the presence of measurement noise and
that bias and variance of these estimates are reduced compared to conventional
approaches. The application to experimental data allowed the parametrization and
subsequent refinement of the model using additional mechanisms. Among other results,
model-based hypothesis testing predicted lymphatic vessel-dependent concentration
of heparan sulfate, the binding partner of CCL21. The selected model provided
an accurate description of the experimental data and was partially validated using
published data. Our findings demonstrate that integrated statistical modelling
of whole imaging data is computationally feasible and can provide novel biological
insights.

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: 'The initial amount of pathogens required to start an infection within a susceptible
host is called the infective dose and is known to vary to a large extent between
different pathogen species. We investigate the hypothesis that the differences
in infective doses are explained by the mode of action in the underlying mechanism
of pathogenesis: Pathogens with locally acting mechanisms tend to have smaller
infective doses than pathogens with distantly acting mechanisms. While empirical
evidence tends to support the hypothesis, a formal theoretical explanation has
been lacking. We give simple analytical models to gain insight into this phenomenon
and also investigate a stochastic, spatially explicit, mechanistic within-host
model for toxin-dependent bacterial infections. The model shows that pathogens
secreting locally acting toxins have smaller infective doses than pathogens secreting
diffusive toxins, as hypothesized. While local pathogenetic mechanisms require
smaller infective doses, pathogens with distantly acting toxins tend to spread
faster and may cause more damage to the host. The proposed model can serve as
a basis for the spatially explicit analysis of various virulence factors also
in the context of other problems in infection dynamics.'

text: We propose a new method for fabricating digital objects through reusable silicone
molds. Molds are generated by casting liquid silicone into custom 3D printed containers
called metamolds. Metamolds automatically define the cuts that are needed to extract
the cast object from the silicone mold. The shape of metamolds is designed through
a novel segmentation technique, which takes into account both geometric and topological
constraints involved in the process of mold casting. Our technique is simple,
does not require changing the shape or topology of the input objects, and only
requires off-the- shelf materials and technologies. We successfully tested our
method on a set of challenging examples with complex shapes and rich geometric
detail. © 2018 Association for Computing Machinery.

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: Cells migrating in multicellular organisms steadily traverse complex three-dimensional
(3D) environments. To decipher the underlying cell biology, current experimental
setups either use simplified 2D, tissue-mimetic 3D (e.g., collagen matrices) or
in vivo environments. While only in vivo experiments are truly physiological,
they do not allow for precise manipulation of environmental parameters. 2D in
vitro experiments do allow mechanical and chemical manipulations, but increasing
evidence demonstrates substantial differences of migratory mechanisms in 2D and
3D. Here, we describe simple, robust, and versatile “pillar forests” to investigate
cell migration in complex but fully controllable 3D environments. Pillar forests
are polydimethylsiloxane-based setups, in which two closely adjacent surfaces
are interconnected by arrays of micrometer-sized pillars. Changing the pillar
shape, size, height and the inter-pillar distance precisely manipulates microenvironmental
parameters (e.g., pore sizes, micro-geometry, micro-topology), while being easily
combined with chemotactic cues, surface coatings, diverse cell types and advanced
imaging techniques. Thus, pillar forests combine the advantages of 2D cell migration
assays with the precise definition of 3D environmental parameters.

text: During epithelial tissue development, repair, and homeostasis, adherens junctions
(AJs) ensure intercellular adhesion and tissue integrity while allowing for cell
and tissue dynamics. Mechanical forces play critical roles in AJs’ composition
and dynamics. Recent findings highlight that beyond a well-established role in
reinforcing cell-cell adhesion, AJ mechanosensitivity promotes junctional remodeling
and polarization, thereby regulating critical processes such as cell intercalation,
division, and collective migration. Here, we provide an integrated view of mechanosensing
mechanisms that regulate cell-cell contact composition, geometry, and integrity
under tension and highlight pivotal roles for mechanosensitive AJ remodeling in
preserving epithelial integrity and sustaining tissue dynamics.

text: Directed migration of cells relies on their ability to sense directional guidance
cues and to interact with pericellular structures in order to transduce contractile
cytoskeletal- into mechanical forces. These biomechanical processes depend highly
on microenvironmental factors such as exposure to 2D surfaces or 3D matrices.
In vivo, the majority of cells are exposed to 3D environments. Data on 3D cell
migration are mostly derived from intravital microscopy or collagen-based in vitro
assays. Both approaches offer only limited controlla-bility of experimental conditions.
Here, we developed an automated microfluidic system that allows positioning of
cells in 3D microenvironments containing highly controlled diffusion-based chemokine
gradients. Tracking migration in such gradients was feasible in real time at the
single cell level. Moreover, the setup allowed on-chip immunocytochemistry and
thus linking of functional with phenotypical properties in individual cells. Spatially
defined retrieval of cells from the device allows down-stream off-chip analysis.
Using dendritic cells as a model, our setup specifically allowed us for the first
time to quantitate key migration characteristics of cells exposed to identical
gradients of the chemokine CCL19 yet placed on 2D vs in 3D environments. Migration
properties between 2D and 3D migration were distinct. Morphological features of
cells migrating in an in vitro 3D environment were similar to those of cells migrating
in animal tissues, but different from cells migrating on a surface. Our system
thus offers a highly controllable in vitro-mimic of a 3D environment that cells
traffic in vivo.

text: Light represents the principal signal driving circadian clock entrainment.
However, how light influences the evolution of the clock remains poorly understood.
The cavefish Phreatichthys andruzzii represents a fascinating model to explore
how evolution under extreme aphotic conditions shapes the circadian clock, since
in this species the clock is unresponsive to light. We have previously demonstrated
that loss-of-function mutations targeting non-visual opsins contribute in part
to this blind clock phenotype. Here, we have compared orthologs of two core clock
genes that play a key role in photic entrainment, cry1a and per2, in both zebrafish
and P. andruzzii. We encountered aberrantly spliced variants for the P. andruzzii
per2 transcript. The most abundant transcript encodes a truncated protein lacking
the C-terminal Cry binding domain and incorporating an intronic, transposon-derived
coding sequence. We demonstrate that the transposon insertion leads to a predominantly
cytoplasmic localization of the cavefish Per2 protein in contrast to the zebrafish
ortholog which is distributed in both the nucleus and cytoplasm. Thus, it seems
that during evolution in complete darkness, the photic entrainment pathway of
the circadian clock has been subject to mutation at multiple levels, extending
from opsin photoreceptors to nuclear effectors.

text: We solve the offline monitoring problem for timed propositional temporal logic
(TPTL), interpreted over dense-time Boolean signals. The variant of TPTL we consider
extends linear temporal logic (LTL) with clock variables and reset quantifiers,
providing a mechanism to specify real-time constraints. We first describe a general
monitoring algorithm based on an exhaustive computation of the set of satisfying
clock assignments as a finite union of zones. We then propose a specialized monitoring
algorithm for the one-variable case using a partition of the time domain based
on the notion of region equivalence, whose complexity is linear in the length
of the signal, thereby generalizing a known result regarding the monitoring of
metric temporal logic (MTL). The region and zone representations of time constraints
are known from timed automata verification and can also be used in the discrete-time
case. Our prototype implementation appears to outperform previous discrete-time
implementations of TPTL monitoring,

text: 'Consider a fully-connected synchronous distributed system consisting of n
nodes, where up to f nodes may be faulty and every node starts in an arbitrary
initial state. In the synchronous C-counting problem, all nodes need to eventually
agree on a counter that is increased by one modulo C in each round for given C>1.
In the self-stabilising firing squad problem, the task is to eventually guarantee
that all non-faulty nodes have simultaneous responses to external inputs: if a
subset of the correct nodes receive an external “go” signal as input, then all
correct nodes should agree on a round (in the not-too-distant future) in which
to jointly output a “fire” signal. Moreover, no node should generate a “fire”
signal without some correct node having previously received a “go” signal as input.
We present a framework reducing both tasks to binary consensus at very small cost.
For example, we obtain a deterministic algorithm for self-stabilising Byzantine
firing squads with optimal resilience f<n/3, asymptotically optimal stabilisation
and response time O(f), and message size O(log f). As our framework does not restrict
the type of consensus routines used, we also obtain efficient randomised solutions.'

atoms are very sensitive to the strength and the direction of the applied magnetic
field. We consider the relevant schemes that ensure the determination of the mutual
spatial orientation of the atoms and the distance between them by entirely optical
means. A corresponding theoretical description is given accounting for the dipole-dipole
interaction between the two atoms in the presence of a magnetic field and for
polarizations of the quantum field interacting with magnetic sublevels of the

text: 'Background: Natural selection shapes cancer genomes. Previous studies used
signatures of positive selection to identify genes driving malignant transformation.
However, the contribution of negative selection against somatic mutations that
affect essential tumor functions or specific domains remains a controversial topic.
Results: Here, we analyze 7546 individual exomes from 26 tumor types from TCGA
data to explore the portion of the cancer exome under negative selection. Although
we find most of the genes neutrally evolving in a pan-cancer framework, we identify
essential cancer genes and immune-exposed protein regions under significant negative
selection. Moreover, our simulations suggest that the amount of negative selection
is underestimated. We therefore choose an empirical approach to identify genes,
functions, and protein regions under negative selection. We find that expression
and mutation status of negatively selected genes is indicative of patient survival.
Processes that are most strongly conserved are those that play fundamental cellular
roles such as protein synthesis, glucose metabolism, and molecular transport.
Intriguingly, we observe strong signals of selection in the immunopeptidome and
proteins controlling peptide exposition, highlighting the importance of immune
surveillance evasion. Additionally, tumor type-specific immune activity correlates
with the strength of negative selection on human epitopes. Conclusions: In summary,
our results show that negative selection is a hallmark of cell essentiality and
immune response in cancer. The functional domains identified could be exploited
therapeutically, ultimately allowing for the development of novel cancer treatments.'

text: Aged proteins can become hazardous to cellular function, by accumulating molecular
damage. This implies that cells should preferentially rely on newly produced ones.
We tested this hypothesis in cultured hippocampal neurons, focusing on synaptic
transmission. We found that newly synthesized vesicle proteins were incorporated
in the actively recycling pool of vesicles responsible for all neurotransmitter
release during physiological activity. We observed this for the calcium sensor
Synaptotagmin 1, for the neurotransmitter transporter VGAT, and for the fusion
protein VAMP2 (Synaptobrevin 2). Metabolic labeling of proteins and visualization
by secondary ion mass spectrometry enabled us to query the entire protein makeup
of the actively recycling vesicles, which we found to be younger than that of
non-recycling vesicles. The young vesicle proteins remained in use for up to ~
24 h, during which they participated in recycling a few hundred times. They were
afterward reluctant to release and were degraded after an additional ~ 24–48 h.
We suggest that the recycling pool of synaptic vesicles relies on newly synthesized
proteins, while the inactive reserve pool contains older proteins.

text: 'AtNHX5 and AtNHX6 are endosomal Na+,K+/H+ antiporters that are critical for
growth and development in Arabidopsis, but the mechanism behind their action remains
unknown. Here, we report that AtNHX5 and AtNHX6, functioning as H+ leak, control
auxin homeostasis and auxin-mediated development. We found that nhx5 nhx6 exhibited
growth variations of auxin-related defects. We further showed that nhx5 nhx6 was
affected in auxin homeostasis. Genetic analysis showed that AtNHX5 and AtNHX6
were required for the function of the ER-localized auxin transporter PIN5. Although
AtNHX5 and AtNHX6 were co-localized with PIN5 at ER, they did not interact directly.
Instead, the conserved acidic residues in AtNHX5 and AtNHX6, which are essential
for exchange activity, were required for PIN5 function. AtNHX5 and AtNHX6 regulated
the pH in ER. Overall, AtNHX5 and AtNHX6 may regulate auxin transport across the
ER via the pH gradient created by their transport activity. H+-leak pathway provides
a fine-tuning mechanism that controls cellular auxin fluxes. '

text: 'This study treats with the influence of a symmetry-breaking transversal magnetic
field on the nonlinear dynamics of ferrofluidic Taylor-Couette flow – flow confined
between two concentric independently rotating cylinders. We detected alternating
‘flip’ solutions which are flow states featuring typical characteristics of slow-fast-dynamics
in dynamical systems. The flip corresponds to a temporal change in the axial wavenumber
and we find them to appear either as pure 2-fold axisymmetric (due to the symmetry-breaking
nature of the applied transversal magnetic field) or involving non-axisymmetric,
helical modes in its interim solution. The latter ones show features of typical
ribbon solutions. In any case the flip solutions have a preferential first axial
wavenumber which corresponds to the more stable state (slow dynamics) and second
axial wavenumber, corresponding to the short appearing more unstable state (fast
dynamics). However, in both cases the flip time grows exponential with increasing
the magnetic field strength before the flip solutions, living on 2-tori invariant
manifolds, cease to exist, with lifetime going to infinity. Further we show that
ferrofluidic flow turbulence differ from the classical, ordinary (usually at high
Reynolds number) turbulence. The applied magnetic field hinders the free motion
of ferrofluid partials and therefore smoothen typical turbulent quantities and
features so that speaking of mildly chaotic dynamics seems to be a more appropriate
expression for the observed motion. '

text: We study the almost-sure termination problem for probabilistic programs. First,
we show that supermartingales with lower bounds on conditional absolute difference
provide a sound approach for the almost-sure termination problem. Moreover, using
this approach we can obtain explicit optimal bounds on tail probabilities of non-termination
within a given number of steps. Second, we present a new approach based on Central
Limit Theorem for the almost-sure termination problem, and show that this approach
can establish almost-sure termination of programs which none of the existing approaches
can handle. Finally, we discuss algorithmic approaches for the two above methods
that lead to automated analysis techniques for almost-sure termination of probabilistic
programs.

text: The precise control of neural stem cell (NSC) proliferation and differentiation
is crucial for the development and function of the human brain. Here, we review
the emerging links between the alteration of embryonic and adult neurogenesis
and the etiology of neuropsychiatric disorders (NPDs) such as autism spectrum
disorders (ASDs) and schizophrenia (SCZ), as well as the advances in stem cell-based
modeling and the novel therapeutic targets derived from these studies.
