text: "The co-evolution of hosts and pathogens is characterized by continuous adaptations
of both parties. Pathogens of social insects need to adapt towards disease defences
at two levels: 1) individual immunity of each colony member consisting of behavioural
defence strategies as well as humoral and cellular immune responses and 2) social
immunity that is collectively performed by all group members comprising behavioural,
physiological and organisational defence strategies.\r\n\r\nTo disentangle the
selection pressure on pathogens by the collective versus individual level of disease
defence in social insects, we performed an evolution experiment using the Argentine
Ant, Linepithema humile, as a host and a mixture of the general insect pathogenic
fungus Metarhizium spp. (6 strains) as a pathogen. We allowed pathogen evolution
over 10 serial host passages to two different evolution host treatments: (1) only
individual host immunity in a single host treatment, and (2) simultaneously acting
individual and social immunity in a social host treatment, in which an exposed
ant was accompanied by two untreated nestmates.\r\n\r\nBefore starting the pathogen
evolution experiment, the 6 Metarhizium spp. strains were characterised concerning
conidiospore size killing rates in singly and socially reared ants, their competitiveness
under coinfecting conditions and their influence on ant behaviour. We analysed
how the ancestral atrain mixture changed in conidiospere size, killing rate and
strain composition dependent on host treatment (single or social hosts) during
10 passages and found that killing rate and conidiospere size of the pathogen
increased under both evolution regimes, but different depending on host treatment.\r\n\r\nTesting
the evolved strain mixtures that evolved under either the single or social host
treatment under both single and social current rearing conditions in a full factorial
design experiment revealed that the additional collective defences in insect societies
add new selection pressure for their coevolving pathogens that compromise their
ability to adapt to its host at the group level. To our knowledge, this is the
first study directly measuring the influence of social immunity on pathogen evolution."

text: Model-based testing is a promising technology for black-box software and hardware
testing, in which test cases are generated automatically from high-level specifications.
Nowadays, systems typically consist of multiple interacting components and, due
to their complexity, testing presents a considerable portion of the effort and
cost in the design process. Exploiting the compositional structure of system specifications
can considerably reduce the effort in model-based testing. Moreover, inferring
properties about the system from testing its individual components allows the
designer to reduce the amount of integration testing. In this paper, we study
compositional properties of the ioco-testing theory. We propose a new approach
to composition and hiding operations, inspired by contract-based design and interface
theories. These operations preserve behaviors that are compatible under composition
and hiding, and prune away incompatible ones. The resulting specification characterizes
the input sequences for which the unit testing of components is sufficient to
infer the correctness of component integration without the need for further tests.
We provide a methodology that uses these results to minimize integration testing
effort, but also to detect potential weaknesses in specifications. While we focus
on asynchronous models and the ioco conformance relation, the resulting methodology
can be applied to a broader class of systems.

text: We consider Markov decision processes (MDPs) which are a standard model for
probabilistic systems.We focus on qualitative properties forMDPs that can express
that desired behaviors of the system arise almost-surely (with probability 1)
or with positive probability. We introduce a new simulation relation to capture
the refinement relation ofMDPs with respect to qualitative properties, and present
discrete graph theoretic algorithms with quadratic complexity to compute the simulation
relation.We present an automated technique for assume-guarantee style reasoning
for compositional analysis ofMDPs with qualitative properties by giving a counterexample
guided abstraction-refinement approach to compute our new simulation relation.
We have implemented our algorithms and show that the compositional analysis leads
to significant improvements.

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 games.\r\nIn this paper we propose
a new notion of equilibria, called doomsday equilibria, which is a strategy profile
such that 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.\r\nWe 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: Theta-gamma network oscillations are thought to represent key reference signals
for information processing in neuronal ensembles, but the underlying synaptic
mechanisms remain unclear. To address this question, we performed whole-cell (WC)
patch-clamp recordings from mature hippocampal granule cells (GCs) in vivo in
the dentate gyrus of anesthetized and awake rats. GCs in vivo fired action potentials
at low frequency, consistent with sparse coding in the dentate gyrus. GCs were
exposed to barrages of fast AMPAR-mediated excitatory postsynaptic currents (EPSCs),
primarily relayed from the entorhinal cortex, and inhibitory postsynaptic currents
(IPSCs), presumably generated by local interneurons. EPSCs exhibited coherence
with the field potential predominantly in the theta frequency band, whereas IPSCs
showed coherence primarily in the gamma range. Action potentials in GCs were phase
locked to network oscillations. Thus, theta-gamma-modulated synaptic currents
may provide a framework for sparse temporal coding of information in the dentate
gyrus.

text: Plant growth is achieved predominantly by cellular elongation, which is thought
to be controlled on several levels by apoplastic auxin. Auxin export into the
apoplast is achieved by plasma membrane efflux catalysts of the PIN-FORMED (PIN)
and ATP-binding cassette protein subfamily B/phosphor- glycoprotein (ABCB/PGP)
classes; the latter were shown to depend on interaction with the FKBP42, TWISTED
DWARF1 (TWD1). Here by using a transgenic approach in combination with phenotypical,
biochemical and cell biological analyses we demonstrate the importance of a putative
C-terminal in-plane membrane anchor of TWD1 in the regulation of ABCB-mediated
auxin transport. In contrast with dwarfed twd1 loss-of-function alleles, TWD1
gain-of-function lines that lack a putative in-plane membrane anchor (HA-TWD1-Ct)
show hypermorphic plant architecture, characterized by enhanced stem length and
leaf surface but reduced shoot branching. Greater hypocotyl length is the result
of enhanced cell elongation that correlates with reduced polar auxin transport
capacity for HA-TWD1-Ct. As a consequence, HA-TWD1-Ct displays higher hypocotyl
auxin accumulation, which is shown to result in elevated auxin-induced cell elongation
rates. Our data highlight the importance of C-terminal membrane anchoring for
TWD1 action, which is required for specific regulation of ABCB-mediated auxin
transport. These data support a model in which TWD1 controls lateral ABCB1-mediated
export into the apoplast, which is required for auxin-mediated cell elongation.

text: This work investigates the transition between different traveling helical
waves (spirals, SPIs) in the setup of differentially independent rotating cylinders.
We use direct numerical simulations to consider an infinite long and periodic
Taylor-Couette apparatus with fixed axial periodicity length. We find so-called
mixed-cross-spirals (MCSs), that can be seen as nonlinear superpositions of SPIs,
to establish stable footbridges connecting SPI states. While bridging the bifurcation
branches of SPIs, the corresponding contributions within the MCS vary continuously
with the control parameters. Here discussed MCSs presenting footbridge solutions
start and end in different SPI branches. Therefore they differ significantly from
the already known MCSs that present bypass solutions (Altmeyer and Hoffmann 2010
New J. Phys. 12 113035). The latter start and end in the same SPI branch, while
they always bifurcate out of those SPI branches with the larger mode amplitude.
Meanwhile, these only appear within the coexisting region of both SPIs. In contrast,
the footbridge solutions can also bifurcate out of the minor SPI contribution.
We also find they exist in regions where only one of the SPIs contributions exists.
In addition, MCS as footbridge solution can appear either stable or unstable.
The latter detected transient solutions offer similar spatio-temporal characteristics
to the flow establishing stable footbridges. Such transition processes are interesting
for pattern-forming systems in general because they accomplish transitions between
traveling waves of different azimuthal wave numbers and have not been described
in the literature yet.

text: The unfolded protein response (UPR) is a signaling network triggered by overload
of protein-folding demand in the endoplasmic reticulum (ER), a condition termed
ER stress. The UPR is critical for growth and development; nonetheless, connections
between the UPR and other cellular regulatory processes remain largely unknown.
Here, we identify a link between the UPR and the phytohormone auxin, a master
regulator of plant physiology. We show that ER stress triggers down-regulation
of auxin receptors and transporters in Arabidopsis thaliana. We also demonstrate
that an Arabidopsis mutant of a conserved ER stress sensor IRE1 exhibits defects
in the auxin response and levels. These data not only support that the plant IRE1
is required for auxin homeostasis, they also reveal a species-specific feature
of IRE1 in multicellular eukaryotes. Furthermore, by establishing that UPR activation
is reduced in mutants of ER-localized auxin transporters, including PIN5, we define
a long-neglected biological significance of ER-based auxin regulation. We further
examine the functional relationship of IRE1 and PIN5 by showing that an ire1 pin5
triple mutant enhances defects of UPR activation and auxin homeostasis in ire1
or pin5. Our results imply that the plant UPR has evolved a hormone-dependent
strategy for coordinating ER function with physiological processes.

text: 'Muller games are played by two players moving a token along a graph; the
winner is determined by the set of vertices that occur infinitely often. The central
algorithmic problem is to compute the winning regions for the players. Different
classes and representations of Muller games lead to problems of varying computational
complexity. One such class are parity games; these are of particular significance
in computational complexity, as they remain one of the few combinatorial problems
known to be in NP ∩ co-NP but not known to be in P. We show that winning regions
for a Muller game can be determined from the alternating structure of its traps.
To every Muller game we then associate a natural number that we call its trap
depth; this parameter measures how complicated the trap structure is. We present
algorithms for parity games that run in polynomial time for graphs of bounded
trap depth, and in general run in time exponential in the trap depth. '

text: 'The brain demands high-energy supply and obstruction of blood flow causes
rapid deterioration of the healthiness of brain cells. Two major events occur
upon ischemia: acidosis and liberation of excess glutamate, which leads to excitotoxicity.
However, cellular source of glutamate and its release mechanism upon ischemia
remained unknown. Here we show a causal relationship between glial acidosis and
neuronal excitotoxicity. As the major cation that flows through channelrhodopsin-2
(ChR2) is proton, this could be regarded as an optogenetic tool for instant intracellular
acidification. Optical activation of ChR2 expressed in glial cells led to glial
acidification and to release of glutamate. On the other hand, glial alkalization
via optogenetic activation of a proton pump, archaerhodopsin (ArchT), led to cessation
of glutamate release and to the relief of ischemic brain damage in vivo. Our results
suggest that controlling glial pH may be an effective therapeutic strategy for
intervention of ischemic brain damage.'

text: Motivated by applications in biology, we present an algorithm for estimating
the length of tube-like shapes in 3-dimensional Euclidean space. In a first step,
we combine the tube formula of Weyl with integral geometric methods to obtain
an integral representation of the length, which we approximate using a variant
of the Koksma-Hlawka Theorem. In a second step, we use tools from computational
topology to decrease the dependence on small perturbations of the shape. We present
computational experiments that shed light on the stability and the convergence
rate of our algorithm.

text: Mechanically coupled cells can generate forces driving cell and tissue morphogenesis
during development. Visualization and measuring of these forces is of major importance
to better understand the complexity of the biomechanic processes that shape cells
and tissues. Here, we describe how UV laser ablation can be utilized to quantitatively
assess mechanical tension in different tissues of the developing zebrafish and
in cultures of primary germ layer progenitor cells ex vivo.

text: 'In machine learning, the domain adaptation problem arrives when the test
(tar-get) and the train (source) data are generated from different distributions. A
key applied issue is thus the design of algorithms able to generalize on a new
distribution, for which we have no label information. We focus on learning classification
models defined as a weighted majority vote over a set of real-valued functions.
In this context, Germain et al. (2013) have shown that a measure of disagreement
between these functions is crucial to control. The core of this measure is a theoretical
bound—the C-bound (Lacasse et al., 2007)—which involves the disagreement and leads
to a well performing majority vote learn-ing algorithm in usual non-adaptative
supervised setting: MinCq. In this work,we propose a framework to extend MinCq
to a domain adaptation scenario.This procedure takes advantage of the recent perturbed
variation divergence between distributions proposed by Harel and Mannor (2012). Justified
by a theoretical bound on the target risk of the vote, we provide to MinCq a
tar-get sample labeled thanks to a perturbed variation-based self-labeling focused
on the regions where the source and target marginals appear similar. We also
study the influence of our self-labeling, from which we deduce an original process
for tuning the hyperparameters. Finally, our framework called PV-MinCq shows very
promising results on a rotation and translation synthetic problem.'

text: Selection for disease control is believed to have contributed to shape the
organisation of insect societies — leading to interaction patterns that mitigate
disease transmission risk within colonies, conferring them ‘organisational immunity’.
Recent studies combining epidemiological models with social network analysis have
identified general properties of interaction networks that may hinder propagation
of infection within groups. These can be prophylactic and/or induced upon pathogen
exposure. Here we review empirical evidence for these two types of organisational
immunity in social insects and describe the individual-level behaviours that underlie
it. We highlight areas requiring further investigation, and emphasise the need
for tighter links between theory and empirical research and between individual-level
and collective-level analyses.

text: We present the design and performance characterization of a new experimental
technique for measuring individual particle charges in large ensembles of macroscopic
grains. The measurement principle is qualitatively similar to that used in determining
the elementary charge by Millikan in that it follows individual particle trajectories.
However, by taking advantage of new technology we are able to work with macroscopic
grains and achieve several orders of magnitude better resolution in charge to
mass ratios. By observing freely falling grains accelerated in a horizontal electric
field with a co-falling, high-speed video camera, we dramatically increase particle
tracking time and measurement precision. Keeping the granular medium under vacuum,
we eliminate air drag, leaving the electrostatic force as the primary source of
particle accelerations in the co-moving frame. Because the technique is based
on direct imaging, we can distinguish between different particle types during
the experiment, opening up the possibility of studying charge transfer processes
between different particle species. For the ∼300 μm diameter grains reported here,
we achieve an average acceleration resolution of ∼0.008 m/s2, a force resolution
of ∼500 pN, and a median charge resolution ∼6× 104 elementary charges per grain
(corresponding to surface charge densities ∼1 elementary charges per μm2). The
primary source of error is indeterminacy in the grain mass, but with higher resolution
cameras and better optics this can be further improved. The high degree of resolution
and the ability to visually identify particles of different species or sizes with
direct imaging make this a powerful new tool to characterize charging processes
in granular media.

text: We present the spatially resolved Hα dynamics of 16 star-forming galaxies
at z ∼ 0.81 using the new KMOS multi-object integral field spectrograph on the
ESO Very Large Telescope. These galaxies, selected using 1.18 μm narrowband imaging
from the 10 deg2 CFHT-HiZELS survey of the SA 22 hr field, are found in a ∼4 Mpc
overdensity of Hα emitters and likely reside in a group/intermediate environment,
but not a cluster. We confirm and identify a rich group of star-forming galaxies
at z = 0.813 ± 0.003, with 13 galaxies within 1000 km s−1 of each other, and seven
within a diameter of 3 Mpc. All of our galaxies are “typical” star-forming galaxies
at their redshift, 0.8 ± 0.4 SFR$^*_{z = 0.8}$, spanning a range of specific star
formation rates (sSFRs) of 0.2–1.1 Gyr−1 and have a median metallicity very close
to solar of 12 + log(O/H) = 8.62 ± 0.06. We measure the spatially resolved Hα
dynamics of the galaxies in our sample and show that 13 out of 16 galaxies can
be described by rotating disks and use the data to derive inclination corrected
rotation speeds of 50–275 km s−1. The fraction of disks within our sample is 75%
± 8%, consistent with previous results based on Hubble Space Telescope morphologies
of Hα-selected galaxies at z ∼ 1 and confirming that disks dominate the SFR density
at z ∼ 1. Our Hα galaxies are well fitted by the z ∼ 1–2 Tully–Fisher (TF) relation,
confirming the evolution seen in the zero point. Apart from having, on average,
higher stellar masses and lower sSFRs, our group galaxies at z = 0.81 present
the same mass–metallicity and TF relation as z ∼ 1 field galaxies and are all
disk galaxies.

text: 'We describe a model experiment for dynamic jamming: a two-dimensional collection
of initially unjammed disks that are forced into the jammed state by uniaxial
compression via a rake. This leads to a stable densification front that travels
ahead of the rake, leaving regions behind it jammed. Using disk conservation in
conjunction with an upper limit to the packing fraction at jamming onset, we predict
the front speed as a function of packing fraction and rake speed. However, we
find that the jamming front has a finite width, a feature that cannot be explained
by disk conservation alone. This width appears to diverge on approach to jamming,
which suggests that it may be related to growing lengthscales encountered in other
jamming studies.'

text: "Given only the URL of a Web page, can we identify its language? In this article
we examine this question. URL-based language classification is useful when the
content of the Web page is not available or downloading the content is a waste
of bandwidth and time.\r\nWe built URL-based language classifiers for English,
German, French, Spanish, and Italian by applying a variety of algorithms and features.
As algorithms we used machine learning algorithms which are widely applied for
text classification and state-of-art algorithms for language identification of
text. As features we used words, various sized n-grams, and custom-made features
(our novel feature set). We compared our approaches with two baseline methods,
namely classification by country code top-level domains and classification by
IP addresses of the hosting Web servers.\r\n\r\nWe trained and tested our classifiers
in a 10-fold cross-validation setup on a dataset obtained from the Open Directory
Project and from querying a commercial search engine. We obtained the lowest F1-measure
for English (94) and the highest F1-measure for German (98) with the best performing
classifiers.\r\n\r\nWe also evaluated the performance of our methods: (i) on a
set of Web pages written in Adobe Flash and (ii) as part of a language-focused
crawler. In the first case, the content of the Web page is hard to extract and
in the second page downloading pages of the “wrong” language constitutes a waste
of bandwidth. In both settings the best classifiers have a high accuracy with
an F1-measure between 95 (for English) and 98 (for Italian) for the Adobe Flash
pages and a precision between 90 (for Italian) and 97 (for French) for the language-focused
crawler."

text: The packing arrangement of individual particles inside a granular material
and the resulting response to applied stresses depend critically on particle-particle
interactions. One aspect that recently received attention are nanoscale surface
features of particles, which play an important role in determining the strength
of cohesive van der Waals and capillary interactions and also affect tribo-charging
of grains. We describe experiments on freely falling granular streams that can
detect the contributions from all three of these forces. We show that it is possible
to measure the charge of individual grains and build up distributions that are
detailed enough to provide stringent tests of tribo-charging models currently
available. A second aspect concerns particle shape. In this case steric interactions
become important and new types of aggregate behavior can be expected when non-convex
particle shapes are considered that can interlock or entangle. However, a general
connection between the mechanical response of a granular material and the constituents\'
shape remains unknown. This has made it infeasible to tackle the "inverse
packing problem", namely to start from a given, desired behavior for the
aggregate as a whole and then find the particle shape the produces it. We discuss
a new approach, using concepts rooted in artificial evolution that provides a
way to solve this inverse problem. This approach facilitates exploring the role
of arbitrary particle geometry in jammed systems and invites the discovery and
design of granular matter with optimized properties.
