text: We propose an efficient method to model paper tearing in the context of interactive
modeling. The method uses geometrical information to automatically detect potential
starting points of tears. We further introduce a new hybrid geometrical and physical-based
method to compute the trajectory of tears while procedurally synthesizing high
resolution details of the tearing path using a texture based approach. The results
obtained are compared with real paper and with previous studies on the expected
geometric paths of paper that tears.

text: Trafficking cells frequently transmigrate through epithelial and endothelial
monolayers. How monolayers cooperate with the penetrating cells to support their
transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic
capillaries as a model system for transendothelial migration. We find that the
chemokine CCL21, which is the decisive guidance cue for intravasation, mainly
localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial
cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes
extracellularly enriched at the sites of endothelial cell-cell junctions. When
we reconstitute the transmigration process in vitro, we find that secretion of
CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and
selective calcium chelation in lymphatic endothelium attenuates transmigration.
Altogether, our data demonstrate a chemokine-mediated feedback between DCs and
lymphatic endothelium, which facilitates transendothelial migration.

text: Navigation of cells along gradients of guidance cues is a determining step
in many developmental and immunological processes. Gradients can either be soluble
or immobilized to tissues as demonstrated for the haptotactic migration of dendritic
cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate
how gradient characteristics govern cellular response patterns, we here introduce
an in vitro system allowing to track migratory responses of DCs to precisely controlled
immobilized gradients of CCL21. We find that haptotactic sensing depends on the
absolute CCL21 concentration and local steepness of the gradient, consistent with
a scenario where DC directionality is governed by the signal-to-noise ratio of
CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC
guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore,
we find that CCR7 signal termination by the G-protein-coupled receptor kinase
6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient
sensing in vitro and confirm those observations in vivo. These findings suggest
that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal
guidance in vivo.

text: The INO80 complex (INO80-C) is an evolutionarily conserved nucleosome remodeler
that acts in transcription, replication, and genome stability. It is required
for resistance against genotoxic agents and is involved in the repair of DNA double-strand
breaks (DSBs) by homologous recombination (HR). However, the causes of the HR
defect in INO80-C mutant cells are controversial. Here, we unite previous findings
using a system to study HR with high spatial resolution in budding yeast. We find
that INO80-C has at least two distinct functions during HR—DNA end resection and
presynaptic filament formation. Importantly, the second function is linked to
the histone variant H2A.Z. In the absence of H2A.Z, presynaptic filament formation
and HR are restored in INO80-C-deficient mutants, suggesting that presynaptic
filament formation is the crucial INO80-C function during HR.

text: The seminal observation that mechanical signals can elicit changes in biochemical
signalling within cells, a process commonly termed mechanosensation and mechanotransduction,
has revolutionized our understanding of the role of cell mechanics in various
fundamental biological processes, such as cell motility, adhesion, proliferation
and differentiation. In this Review, we will discuss how the interplay and feedback
between mechanical and biochemical signals control tissue morphogenesis and cell
fate specification in embryonic development.

text: Two-player games on graphs provide the theoretical framework for many important
problems such as reactive synthesis. While the traditional study of two-player
zero-sum games has been extended to multi-player games with several notions of
equilibria, they are decidable only for perfect-information games, whereas several
applications require imperfect-information. In this paper we propose a new notion
of equilibria, called doomsday equilibria, which is a strategy profile where all
players satisfy their own objective, and if any coalition of players deviates
and violates even one of the players' objective, then the objective of every player
is violated. We present algorithms and complexity results for deciding the existence
of doomsday equilibria for various classes of ω-regular objectives, both for imperfect-information
games, and for perfect-information games. We provide optimal complexity bounds
for imperfect-information games, and in most cases for perfect-information games.

text: In classical machine learning, regression is treated as a black box process
of identifying a suitable function from a hypothesis set without attempting to
gain insight into the mechanism connecting inputs and outputs. In the natural
sciences, however, finding an interpretable function for a phenomenon is the prime
goal as it allows to understand and generalize results. This paper proposes a
novel type of function learning network, called equation learner (EQL), that can
learn analytical expressions and is able to extrapolate to unseen domains. It
is implemented as an end-to-end differentiable feed-forward network and allows
for efficient gradient based training. Due to sparsity regularization concise
interpretable expressions can be obtained. Often the true underlying source expression
is identified.

text: We generalize winning conditions in two-player games by adding a structural
acceptance condition called obligations. Obligations are orthogonal to the linear
winning conditions that define whether a play is winning. Obligations are a declaration
that player 0 can achieve a certain value from a configuration. If the obligation
is met, the value of that configuration for player 0 is 1. We define the value
in such games and show that obligation games are determined. For Markov chains
with Borel objectives and obligations, and finite turn-based stochastic parity
games with obligations we give an alternative and simpler characterization of
the value function. Based on this simpler definition we show that the decision
problem of winning finite turn-based stochastic parity games with obligations
is in NP∩co-NP. We also show that obligation games provide a game framework for
reasoning about p-automata. © 2017 The Association for Symbolic Logic.

text: By applying methods and principles from the physical sciences to biological
problems, D'Arcy Thompson's On Growth and Form demonstrated how mathematical reasoning
reveals elegant, simple explanations for seemingly complex processes. This has
had a profound influence on subsequent generations of developmental biologists.
We discuss how this influence can be traced through twentieth century morphologists,
embryologists and theoreticians to current research that explores the molecular
and cellular mechanisms of tissue growth and patterning, including our own studies
of the vertebrate neural tube.

text: 'We show that the framework of topological data analysis can be extended from
metrics to general Bregman divergences, widening the scope of possible applications.
Examples are the Kullback - Leibler divergence, which is commonly used for comparing
text and images, and the Itakura - Saito divergence, popular for speech and sound.
In particular, we prove that appropriately generalized čech and Delaunay (alpha)
complexes capture the correct homotopy type, namely that of the corresponding
union of Bregman balls. Consequently, their filtrations give the correct persistence
diagram, namely the one generated by the uniformly growing Bregman balls. Moreover,
we show that unlike the metric setting, the filtration of Vietoris-Rips complexes
may fail to approximate the persistence diagram. We propose algorithms to compute
the thus generalized čech, Vietoris-Rips and Delaunay complexes and experimentally
test their efficiency. Lastly, we explain their surprisingly good performance
by making a connection with discrete Morse theory. '
