text: 'Brain function is mediated by complex dynamical interactions between excitatory
and inhibitory cell types. The Cholecystokinin-expressing inhibitory cells (CCK-interneurons)
are one of the least studied types, despite being suspected to play important
roles in cognitive processes. We studied the network effects of optogenetic silencing
of CCK-interneurons in the CA1 hippocampal area during exploration and sleep states.
The cell firing pattern in response to light pulses allowed us to classify the
recorded neurons in 5 classes, including disinhibited and non-responsive pyramidal
cell and interneurons, and the inhibited interneurons corresponding to the CCK
group. The light application, which inhibited the activity of CCK interneurons
triggered wider changes in the firing dynamics of cells. We observed rate changes
(i.e. remapping) of pyramidal cells during the exploration session in which the
light was applied relative to the previous control session that was not restricted
neither in time nor space to the light delivery. Also, the disinhibited pyramidal
cells had higher increase in bursting than in single spike firing rate as a result
of CCK silencing. In addition, the firing activity patterns during exploratory
periods were more weakly reactivated in sleep for those periods in which CCK-interneuron
were silenced than in the unaffected periods. Furthermore, light pulses during
sleep disrupted the reactivation of recent waking patterns. Hence, silencing CCK
neurons during exploration suppressed the reactivation of waking firing patterns
in sleep and CCK interneuron activity was also required during sleep for the normal
reactivation of waking patterns. These findings demonstrate the involvement of
CCK cells in reactivation-related memory consolidation. An important part of our
analysis was to test the relationship of the identified CCKinterneurons to brain
oscillations. Our findings showed that these cells exhibited different oscillatory
behaviour during anaesthesia and natural waking and sleep conditions. We showed
that: 1) Contrary to the past studies performed under anaesthesia, the identified
CCKinterneurons fired on the descending portion of the theta phase in waking exploration.
2) CCKinterneuron preferred phases around the trough of gamma oscillations. 3)
Contrary to anaesthesia conditions, the average firing rate of the CCK-interneurons
increased around the peak activity of the sharp-wave ripple (SWR) events in natural
sleep, which is congruent with new reports about their functional connectivity.
We also found that light driven CCK-interneuron silencing altered the dynamics
on the CA1 network oscillatory activity: 1) Pyramidal cells negatively shifted
their preferred theta phases when the light was applied, while interneurons responses
were less consistent. 2) As a population, pyramidal cells negatively shifted their
preferred activity during gamma oscillations, albeit we did not find gamma modulation
differences related to the light application when pyramidal cells were subdivided
into the disinhibited and unaffected groups. 3) During the peak of SWR events,
all but the CCK-interneurons had a reduction in their relative firing rate change
during the light application as compared to the change observed at SWR initiation.
Finally, regarding to the place field activity of the recorded pyramidal neurons,
we showed that the disinhibited pyramidal cells had reduced place field similarity,
coherence and spatial information, but only during the light application. The
mechanisms behind such observed behaviours might involve eCB signalling and plastic
changes in CCK-interneuron synapses. In conclusion, the observed changes related
to the light-mediated silencing of CCKinterneurons have unravelled characteristics
of this interneuron subpopulation that might change the understanding not only
of their particular network interactions, but also of the current theories about
the emergence of certain cognitive processes such as place coding needed for navigation
or hippocampus-dependent memory consolidation. '

text: Many traits of interest are highly heritable and genetically complex, meaning
that much of the variation they exhibit arises from differences at numerous loci
in the genome. Complex traits and their evolution have been studied for more than
a century, but only in the last decade have genome-wide association studies (GWASs)
in humans begun to reveal their genetic basis. Here, we bring these threads of
research together to ask how findings from GWASs can further our understanding
of the processes that give rise to heritable variation in complex traits and of
the genetic basis of complex trait evolution in response to changing selection
pressures (i.e., of polygenic adaptation). Conversely, we ask how evolutionary
thinking helps us to interpret findings from GWASs and informs related efforts
of practical importance.

text: 'Plant mating systems play a key role in structuring genetic variation both
within and between species. In hybrid zones, the outcomes and dynamics of hybridization
are usually interpreted as the balance between gene flow and selection against
hybrids. Yet, mating systems can introduce selective forces that alter these expectations;
with diverse outcomes for the level and direction of gene flow depending on variation
in outcrossing and whether the mating systems of the species pair are the same
or divergent. We present a survey of hybridization in 133 species pairs from 41
plant families and examine how patterns of hybridization vary with mating system.
We examine if hybrid zone mode, level of gene flow, asymmetries in gene flow and
the frequency of reproductive isolating barriers vary in relation to mating system/s
of the species pair. We combine these results with a simulation model and examples
from the literature to address two general themes: (i) the two‐way interaction
between introgression and the evolution of reproductive systems, and (ii) how
mating system can facilitate or restrict interspecific gene flow. We conclude
that examining mating system with hybridization provides unique opportunities
to understand divergence and the processes underlying reproductive isolation.'

text: "Gene Drives are regarded as future tools with a high potential for population
control. Due to their inherent ability to overcome the rules of Mendelian inheritance,
gene drives (GD) may spread genes rapidly through populations of sexually reproducing
organisms. A release of organisms carrying a GD would constitute a paradigm shift
in the handling of genetically modified organisms because gene drive organisms
(GDO) are designed to drive their transgenes into wild populations and thereby
increase the number of GDOs. The rapid development in this field and its focus
on wild populations demand a prospective risk assessment with a focus on exposure
related aspects. Presently, it is unclear how adequate risk management could be
guaranteed to limit the spread of GDs in time and space, in order to avoid potential
adverse effects in socio‐ecological systems.\r\n\r\nThe recent workshop on the
“Evaluation of Spatial and Temporal Control of Gene Drives” hosted by the Institute
of Safety/Security and Risk Sciences (ISR) in Vienna aimed at gaining some insight
into the potential population dynamic behavior of GDs and appropriate measures
of control. Scientists from France, Germany, England, and the USA discussed both
topics in this meeting on April 4–5, 2019. This article summarizes results of
the workshop."

text: A novel magnetic scratch method achieves repeatability, reproducibility and
geometric control greater than pipette scratch assays and closely approximating
the precision of cell exclusion assays while inducing the cell injury inherently
necessary for wound healing assays. The magnetic scratch is affordable, easily
implemented and standardisable and thus may contribute toward better comparability
of data generated in different studies and laboratories.

text: "Hyperpolarization-activated cyclic-nucleotide-gated (HCN) channels control
electrical rhythmicity and excitability in the heart and brain, but the function
of HCN channels at the subcellular level in axons remains poorly understood. Here,
we show that the action potential conduction velocity in both myelinated and unmyelinated
central axons can be bidirectionally modulated by a HCN channel blocker, cyclic
adenosine monophosphate (cAMP), and neuromodulators. Recordings from mouse cerebellar
mossy fiber boutons show that HCN channels ensure reliable high-frequency firing
and are strongly modulated by cAMP (EC50 40 mM; estimated endogenous cAMP concentration
13 mM). In addition, immunogold-electron microscopy revealed HCN2 as the dominating
subunit in cerebellar mossy fibers. Computational modeling indicated that HCN2
channels control conduction velocity primarily by altering the resting membrane
potential\r\nand are associated with significant metabolic costs. These results
suggest that the cAMP-HCN pathway provides neuromodulators with an opportunity
to finely tune energy consumption and temporal delays across axons in the brain."

text: 'In two-player games on graphs, the players move a token through a graph to
produce a finite or infinite path, which determines the qualitative winner or
quantitative payoff of the game. We study bidding games in which the players bid
for the right to move the token. Several bidding rules were studied previously.
In Richman bidding, in each round, the players simultaneously submit bids, and
the higher bidder moves the token and pays the other player. Poorman bidding is
similar except that the winner of the bidding pays the "bank" rather than the
other player. Taxman bidding spans the spectrum between Richman and poorman bidding.
They are parameterized by a constant tau in [0,1]: portion tau of the winning
bid is paid to the other player, and portion 1-tau to the bank. While finite-duration
(reachability) taxman games have been studied before, we present, for the first
time, results on infinite-duration taxman games. It was previously shown that
both Richman and poorman infinite-duration games with qualitative objectives reduce
to reachability games, and we show a similar result here. Our most interesting
results concern quantitative taxman games, namely mean-payoff games, where poorman
and Richman bidding differ significantly. A central quantity in these games is
the ratio between the two players'' initial budgets. While in poorman mean-payoff
games, the optimal payoff of a player depends on the initial ratio, in Richman
bidding, the payoff depends only on the structure of the game. In both games the
optimal payoffs can be found using (different) probabilistic connections with
random-turn games in which in each turn, instead of bidding, a coin is tossed
to determine which player moves. While the value with Richman bidding equals the
value of a random-turn game with an un-biased coin, with poorman bidding, the
bias in the coin is the initial ratio of the budgets. We give a complete classification
of mean-payoff taxman games that is based on a probabilistic connection: the value
of a taxman bidding game with parameter tau and initial ratio r, equals the value
of a random-turn game that uses a coin with bias F(tau, r) = (r+tau * (1-r))/(1+tau).
Thus, we show that Richman bidding is the exception; namely, for every tau <1,
the value of the game depends on the initial ratio. Our proof technique simplifies
and unifies the previous proof techniques for both Richman and poorman bidding. '

text: 'A vector addition system with states (VASS) consists of a finite set of states
and counters. A configuration is a state and a value for each counter; a transition
changes the state and each counter is incremented, decremented, or left unchanged.
While qualitative properties such as state and configuration reachability have
been studied for VASS, we consider the long-run average cost of infinite computations
of VASS. The cost of a configuration is for each state, a linear combination of
the counter values. In the special case of uniform cost functions, the linear
combination is the same for all states. The (regular) long-run emptiness problem
is, given a VASS, a cost function, and a threshold value, if there is a (lasso-shaped)
computation such that the long-run average value of the cost function does not
exceed the threshold. For uniform cost functions, we show that the regular long-run
emptiness problem is (a) decidable in polynomial time for integer-valued VASS,
and (b) decidable but nonelementarily hard for natural-valued VASS (i.e., nonnegative
counters). For general cost functions, we show that the problem is (c) NP-complete
for integer-valued VASS, and (d) undecidable for natural-valued VASS. Our most
interesting result is for (c) integer-valued VASS with general cost functions,
where we establish a connection between the regular long-run emptiness problem
and quadratic Diophantine inequalities. The general (nonregular) long-run emptiness
problem is equally hard as the regular problem in all cases except (c), where
it remains open. '

text: 'In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the winner of the game. Such games
are central in formal methods since they model the interaction between a non-terminating
system and its environment. In bidding games the players bid for the right to
move the token: in each round, the players simultaneously submit bids, and the
higher bidder moves the token and pays the other player. Bidding games are known
to have a clean and elegant mathematical structure that relies on the ability
of the players to submit arbitrarily small bids. Many applications, however, require
a fixed granularity for the bids, which can represent, for example, the monetary
value expressed in cents. We study, for the first time, the combination of discrete-bidding
and infinite-duration games. Our most important result proves that these games
form a large determined subclass of concurrent games, where determinacy is the
strong property that there always exists exactly one player who can guarantee
winning the game. In particular, we show that, in contrast to non-discrete bidding
games, the mechanism with which tied bids are resolved plays an important role
in discrete-bidding games. We study several natural tie-breaking mechanisms and
show that, while some do not admit determinacy, most natural mechanisms imply
determinacy for every pair of initial budgets. '

text: 'The fundamental model-checking problem, given as input a model and a specification,
asks for the algorithmic verification of whether the model satisfies the specification.
Two classical models for reactive systems are graphs and Markov decision processes
(MDPs). A basic specification formalism in the verification of reactive systems
is the strong fairness (aka Streett) objective, where given different types of
requests and corresponding grants, the requirement is that for each type, if the
request event happens infinitely often, then the corresponding grant event must
also happen infinitely often. All omega-regular objectives can be expressed as
Streett objectives and hence they are canonical in verification. Consider graphs/MDPs
with n vertices, m edges, and a Streett objectives with k pairs, and let b denote
the size of the description of the Streett objective for the sets of requests
and grants. The current best-known algorithm for the problem requires time O(min(n^2,
m sqrt{m log n}) + b log n). In this work we present randomized near-linear time
algorithms, with expected running time O~(m + b), where the O~ notation hides
poly-log factors. Our randomized algorithms are near-linear in the size of the
input, and hence optimal up to poly-log factors. '

text: In this paper, we design novel liquid time-constant recurrent neural networks
for robotic control, inspired by the brain of the nematode, C. elegans. In the
worm's nervous system, neurons communicate through nonlinear time-varying synaptic
links established amongst them by their particular wiring structure. This property
enables neurons to express liquid time-constants dynamics and therefore allows
the network to originate complex behaviors with a small number of neurons. We
identify neuron-pair communication motifs as design operators and use them to
configure compact neuronal network structures to govern sequential robotic tasks.
The networks are systematically designed to map the environmental observations
to motor actions, by their hierarchical topology from sensory neurons, through
recurrently-wired interneurons, to motor neurons. The networks are then parametrized
in a supervised-learning scheme by a search-based algorithm. We demonstrate that
obtained networks realize interpretable dynamics. We evaluate their performance
in controlling mobile and arm robots, and compare their attributes to other artificial
neural network-based control agents. Finally, we experimentally show their superior
resilience to environmental noise, compared to the existing machine learning-based
methods.

text: 'We study Markov decision processes and turn-based stochastic games with parity
conditions. There are three qualitative winning criteria, namely, sure winning,
which requires all paths to satisfy the condition, almost-sure winning, which
requires the condition to be satisfied with probability 1, and limit-sure winning,
which requires the condition to be satisfied with probability arbitrarily close
to 1. We study the combination of two of these criteria for parity conditions,
e.g., there are two parity conditions one of which must be won surely, and the
other almost-surely. The problem has been studied recently by Berthon et al. for
MDPs with combination of sure and almost-sure winning, under infinite-memory strategies,
and the problem has been established to be in NP cap co-NP. Even in MDPs there
is a difference between finite-memory and infinite-memory strategies. Our main
results for combination of sure and almost-sure winning are as follows: (a) we
show that for MDPs with finite-memory strategies the problem is in NP cap co-NP;
(b) we show that for turn-based stochastic games the problem is co-NP-complete,
both for finite-memory and infinite-memory strategies; and (c) we present algorithmic
results for the finite-memory case, both for MDPs and turn-based stochastic games,
by reduction to non-stochastic parity games. In addition we show that all the
above complexity results also carry over to combination of sure and limit-sure
winning, and results for all other combinations can be derived from existing results
in the literature. Thus we present a complete picture for the study of combinations
of two qualitative winning criteria for parity conditions in MDPs and turn-based
stochastic games. '

text: "While cells of mesenchymal or epithelial origin perform their effector functions
in a purely anchorage dependent manner, cells derived from the hematopoietic lineage
are not committed to operate only within a specific niche. Instead, these cells
are able to function autonomously of the molecular composition in a broad range
of tissue compartments. By this means, cells of the hematopoietic lineage retain
the capacity to disseminate into connective tissue and recirculate between organs,
building the foundation for essential processes such as tissue regeneration or
immune surveillance. \r\nCells of the immune system, specifically leukocytes,
are extraordinarily good at performing this task. These cells are able to flexibly
shift their mode of migration between an adhesion-mediated and an adhesion-independent
manner, instantaneously accommodating for any changes in molecular composition
of the external scaffold. The key component driving directed leukocyte migration
is the chemokine receptor 7, which guides the cell along gradients of chemokine
ligand. Therefore, the physical destination of migrating leukocytes is purely
deterministic, i.e. given by global directional cues such as chemokine gradients.
\r\nNevertheless, these cells typically reside in three-dimensional scaffolds
of inhomogeneous complexity, raising the question whether cells are able to locally
discriminate between multiple optional migration routes. Current literature provides
evidence that leukocytes, specifically dendritic cells, do indeed probe their
surrounding by virtue of multiple explorative protrusions. However, it remains
enigmatic how these cells decide which one is the more favorable route to follow
and what are the key players involved in performing this task. Due to the heterogeneous
environment of most tissues, and the vast adaptability of migrating leukocytes,
at this time it is not clear to what extent leukocytes are able to optimize their
migratory strategy by adapting their level of adhesiveness. And, given the fact
that leukocyte migration is characterized by branched cell shapes in combination
with high migration velocities, it is reasonable to assume that these cells require
fine tuned shape maintenance mechanisms that tightly coordinate protrusion and
adhesion dynamics in a spatiotemporal manner. \r\nTherefore, this study aimed
to elucidate how rapidly migrating leukocytes opt for an ideal migratory path
while maintaining a continuous cell shape and balancing adhesive forces to efficiently
navigate through complex microenvironments. \r\nThe results of this study unraveled
a role for the microtubule cytoskeleton in promoting the decision making process
during path finding and for the first time point towards a microtubule-mediated
function in cell shape maintenance of highly ramified cells such as dendritic
cells. Furthermore, we found that migrating low-adhesive leukocytes are able to
instantaneously adapt to increased tensile load by engaging adhesion receptors.
This response was only occurring tangential to the substrate while adhesive properties
in the vertical direction were not increased. As leukocytes are primed for rapid
migration velocities, these results demonstrate that leukocyte integrins are able
to confer a high level of traction forces parallel to the cell membrane along
the direction of migration without wasting energy in gluing the cell to the substrate.
\r\nThus, the data in the here presented thesis provide new insights into the
pivotal role of cytoskeletal dynamics and the mechanisms of force transduction
during leukocyte migration. \r\nThereby the here presented results help to further
define fundamental principles underlying leukocyte migration and open up potential
therapeutic avenues of clinical relevance.\r\n"

text: "Hybrid automata combine finite automata and dynamical systems, and model
the interaction of digital with physical systems. Formal analysis that can guarantee
the safety of all behaviors or rigorously witness failures, while unsolvable in
general, has been tackled algorithmically using, e.g., abstraction, bounded model-checking,
assisted theorem proving.\r\nNevertheless, very few methods have addressed the
time-unbounded reachability analysis of hybrid automata and, for current sound
and automatic tools, scalability remains critical. We develop methods for the
polyhedral abstraction of hybrid automata, which construct coarse overapproximations
and tightens them incrementally, in a CEGAR fashion. We use template polyhedra,
i.e., polyhedra whose facets are normal to a given set of directions.\r\nWhile,
previously, directions were given by the user, we introduce (1) the first method\r\nfor
computing template directions from spurious counterexamples, so as to generalize
and\r\neliminate them. The method applies naturally to convex hybrid automata,
i.e., hybrid\r\nautomata with (possibly non-linear) convex constraints on derivatives
only, while for linear\r\nODE requires further abstraction. Specifically, we introduce
(2) the conic abstractions,\r\nwhich, partitioning the state space into appropriate
(possibly non-uniform) cones, divide\r\ncurvy trajectories into relatively straight
sections, suitable for polyhedral abstractions.\r\nFinally, we introduce (3) space-time
interpolation, which, combining interval arithmetic\r\nand template refinement,
computes appropriate (possibly non-uniform) time partitioning\r\nand template
directions along spurious trajectories, so as to eliminate them.\r\nWe obtain
sound and automatic methods for the reachability analysis over dense\r\nand unbounded
time of convex hybrid automata and hybrid automata with linear ODE.\r\nWe build
prototype tools and compare—favorably—our methods against the respective\r\nstate-of-the-art
tools, on several benchmarks."

text: The apical hook is a transiently formed structure that plays a protective
role when the germinating seedling penetrates through the soil towards the surface.
Crucial for proper bending is the local auxin maxima, which defines the concave
(inner) side of the hook curvature. As no sign of asymmetric auxin distribution
has been reported in embryonic hypocotyls prior to hook formation, the question
of how auxin asymmetry is established in the early phases of seedling germination
remains largely unanswered. Here, we analyzed the auxin distribution and expression
of PIN auxin efflux carriers from early phases of germination, and show that bending
of the root in response to gravity is the crucial initial cue that governs the
hypocotyl bending required for apical hook formation. Importantly, polar auxin
transport machinery is established gradually after germination starts as a result
of tight root-hypocotyl interaction and a proper balance between abscisic acid
and gibberellins.

text: "Background\r\n\r\nChlamydia are ancient intracellular pathogens with reduced,
though strikingly conserved genome. Despite their parasitic lifestyle and isolated
intracellular environment, these bacteria managed to avoid accumulation of deleterious
mutations leading to subsequent genome degradation characteristic for many parasitic
bacteria.\r\nResults\r\n\r\nWe report pan-genomic analysis of sixteen species
from genus Chlamydia including identification and functional annotation of orthologous
genes, and characterization of gene gains, losses, and rearrangements. We demonstrate
the overall genome stability of these bacteria as indicated by a large fraction
of common genes with conserved genomic locations. On the other hand, extreme evolvability
is confined to several paralogous gene families such as polymorphic membrane proteins
and phospholipase D, and likely is caused by the pressure from the host immune
system.\r\nConclusions\r\n\r\nThis combination of a large, conserved core genome
and a small, evolvable periphery likely reflect the balance between the selective
pressure towards genome reduction and the need to adapt to escape from the host
immunity."

text: Intra-organ communication guides morphogenetic processes that are essential
for an organ to carry out complex physiological functions. In the heart, the growth
of the myocardium is tightly coupled to that of the endocardium, a specialized
endothelial tissue that lines its interior. Several molecular pathways have been
implicated in the communication between these tissues including secreted factors,
components of the extracellular matrix, or proteins involved in cell-cell communication.
Yet, it is unknown how the growth of the endocardium is coordinated with that
of the myocardium. Here, we show that an increased expansion of the myocardial
atrial chamber volume generates higher junctional forces within endocardial cells.
This leads to biomechanical signaling involving VE-cadherin, triggering nuclear
localization of the Hippo pathway transcriptional regulator Yap1 and endocardial
proliferation. Our work suggests that the growth of the endocardium results from
myocardial chamber volume expansion and ends when the tension on the tissue is
relaxed.

text: Across diverse biological systems—ranging from neural networks to intracellular
signaling and genetic regulatory networks—the information about changes in the
environment is frequently encoded in the full temporal dynamics of the network
nodes. A pressing data-analysis challenge has thus been to efficiently estimate
the amount of information that these dynamics convey from experimental data. Here
we develop and evaluate decoding-based estimation methods to lower bound the mutual
information about a finite set of inputs, encoded in single-cell high-dimensional
time series data. For biological reaction networks governed by the chemical Master
equation, we derive model-based information approximations and analytical upper
bounds, against which we benchmark our proposed model-free decoding estimators.
In contrast to the frequently-used k-nearest-neighbor estimator, decoding-based
estimators robustly extract a large fraction of the available information from
high-dimensional trajectories with a realistic number of data samples. We apply
these estimators to previously published data on Erk and Ca2+ signaling in mammalian
cells and to yeast stress-response, and find that substantial amount of information
about environmental state can be encoded by non-trivial response statistics even
in stationary signals. We argue that these single-cell, decoding-based information
estimates, rather than the commonly-used tests for significant differences between
selected population response statistics, provide a proper and unbiased measure
for the performance of biological signaling networks.
