text: cGMP signaling is widespread in the nervous system. However, it has proved
difficult to visualize and genetically probe endogenously evoked cGMP dynamics
in neurons in vivo. Here, we combine cGMP and Ca2+ biosensors to image and dissect
a cGMP signaling network in a Caenorhabditis elegans oxygen-sensing neuron. We
show that a rise in O2 can evoke a tonic increase in cGMP that requires an atypical
O2-binding soluble guanylate cyclase and that is sustained until oxygen levels
fall. Increased cGMP leads to a sustained Ca2+ response in the neuron that depends
on cGMP-gated ion channels. Elevated levels of cGMP and Ca2+ stimulate competing
negative feedback loops that shape cGMP dynamics. Ca2+-dependent negative feedback
loops, including activation of phosphodiesterase-1 (PDE-1), dampen the rise of
cGMP. A different negative feedback loop, mediated by phosphodiesterase-2 (PDE-2)
and stimulated by cGMP-dependent kinase (PKG), unexpectedly promotes cGMP accumulation
following a rise in O2, apparently by keeping in check gating of cGMP channels
and limiting activation of Ca2+-dependent negative feedback loops. Simultaneous
imaging of Ca2+ and cGMP suggests that cGMP levels can rise close to cGMP channels
while falling elsewhere. O2-evoked cGMP and Ca2+ responses are highly reproducible
when the same neuron in an individual animal is stimulated repeatedly, suggesting
that cGMP transduction has high intrinsic reliability. However, responses vary
substantially across individuals, despite animals being genetically identical
and similarly reared. This variability may reflect stochastic differences in expression
of cGMP signaling components. Our work provides in vivo insights into the architecture
of neuronal cGMP signaling.

text: In order to guarantee that each method of a data structure updates the logical
state exactly once, al-most all non-blocking implementations employ Compare-And-Swap
(CAS) based synchronization. For FIFO queue implementations this translates into concurrent enqueue or dequeue methods
competing among themselves to update the same variable, the tail or the head,
respectively, leading to high contention and poor scalability. Recent non-blocking
queue implementations try to alleviate high contentionby increasing the number
of contention points, all the while using CAS-based synchronization. Furthermore,
obtaining a wait-free implementation with competition is achieved by additional
synchronization which leads to further degradation of performance.In this paper
we formalize the notion of competitiveness of a synchronizing statement which
can beused as a measure for the scalability of concurrent implementations. We
present a new queue implementation, the Speculative Pairing (SP) queue, which,
as we show, decreases competitiveness by using Fetch-And-Increment (FAI) instead
of CAS. We prove that the SP queue is linearizable and lock-free.We also show
that replacing CAS with FAI leads to wait-freedom for dequeue methods without
an adverse effect on performance. In fact, our experiments suggest that the SP
queue can perform and scale better than the state-of-the-art queue implementations.

text: We give a cohomological interpretation of both the Kac polynomial and the
refined Donaldson-Thomas-invariants of quivers. This interpretation yields a proof
of a conjecture of Kac from 1982 and gives a new perspective on recent work of
Kontsevich-Soibelman. Thisis achieved by computing, via an arithmetic Fourier
transform, the dimensions of the isotypical components of the cohomology of associated
Nakajima quiver varieties under the action of a Weyl group. The generating function
of the corresponding Poincare polynomials is an extension of Hua's formula for
Kac polynomials of quivers involving Hall-Littlewood symmetric functions. The
resulting formulae contain a wide range of information on the geometry of the
quiver varieties.

text: We show that a natural isomorphism between the rational cohomology groups
of the two zero-dimensional Hilbert schemes of n-points of two surfaces, the affine
plane minus the axes and the cotangent bundle of an elliptic curve, exchanges
the weight filtration on the first set of cohomology groups with the perverse
Leray filtration associated with a natural fibration on the second set of cohomology
groups. We discuss some associated hard Lefschetz phenomena.

text: 'We study two-player zero-sum games over infinite-state graphs equipped with
ωB and finitary conditions. Our first contribution is about the strategy complexity,
i.e the memory required for winning strategies: we prove that over general infinite-state
graphs, memoryless strategies are sufficient for finitary Büchi, and finite-memory
suffices for finitary parity games. We then study pushdown games with boundedness
conditions, with two contributions. First we prove a collapse result for pushdown
games with ωB-conditions, implying the decidability of solving these games. Second
we consider pushdown games with finitary parity along with stack boundedness conditions,
and show that solving these games is EXPTIME-complete.'

text: It is often difficult to correctly implement a Boolean controller for a complex
system, especially when concurrency is involved. Yet, it may be easy to formally
specify a controller. For instance, for a pipelined processor it suffices to state
that the visible behavior of the pipelined system should be identical to a non-pipelined
reference system (Burch-Dill paradigm). We present a novel procedure to efficiently
synthesize multiple Boolean control signals from a specification given as a quantified
first-order formula (with a specific quantifier structure). Our approach uses
uninterpreted functions to abstract details of the design. We construct an unsatisfiable
SMT formula from the given specification. Then, from just one proof of unsatisfiability,
we use a variant of Craig interpolation to compute multiple coordinated interpolants
that implement the Boolean control signals. Our method avoids iterative learning
and back-substitution of the control functions. We applied our approach to synthesize
a controller for a simple two-stage pipelined processor, and present first experimental
results.

text: Choices made by nondeterministic word automata depend on both the past (the
prefix of the word read so far) and the future (the suffix yet to be read). In
several applications, most notably synthesis, the future is diverse or unknown,
leading to algorithms that are based on deterministic automata. Hoping to retain
some of the advantages of nondeterministic automata, researchers have studied
restricted classes of nondeterministic automata. Three such classes are nondeterministic
automata that are good for trees (GFT; i.e., ones that can be expanded to tree
automata accepting the derived tree languages, thus whose choices should satisfy
diverse futures), good for games (GFG; i.e., ones whose choices depend only on
the past), and determinizable by pruning (DBP; i.e., ones that embody equivalent
deterministic automata). The theoretical properties and relative merits of the
different classes are still open, having vagueness on whether they really differ
from deterministic automata. In particular, while DBP ⊆ GFG ⊆ GFT, it is not known
whether every GFT automaton is GFG and whether every GFG automaton is DBP. Also
open is the possible succinctness of GFG and GFT automata compared to deterministic
automata. We study these problems for ω-regular automata with all common acceptance
conditions. We show that GFT=GFG⊃DBP, and describe a determinization construction
for GFG automata.

text: "Motivated by the analysis of highly dynamic message-passing systems, i.e.
unbounded thread creation, mobility, etc. we present a framework for the analysis
of depth-bounded systems. Depth-bounded systems are one of the most expressive
known fragment of the π-calculus for which interesting verification problems are
still decidable. Even though they are infinite state systems depth-bounded systems
are well-structured, thus can be analyzed algorithmically. We give an interpretation
of depth-bounded systems as graph-rewriting systems. This gives more flexibility
and ease of use to apply depth-bounded systems to other type of systems like shared
memory concurrency.\r\n\r\nFirst, we develop an adequate domain of limits for
depth-bounded systems, a prerequisite for the effective representation of downward-closed
sets. Downward-closed sets are needed by forward saturation-based algorithms to
represent potentially infinite sets of states. Then, we present an abstract interpretation
framework to compute the covering set of well-structured transition systems. Because,
in general, the covering set is not computable, our abstraction over-approximates
the actual covering set. Our abstraction captures the essence of acceleration
based-algorithms while giving up enough precision to ensure convergence. We have
implemented the analysis in the PICASSO tool and show that it is accurate in practice.
Finally, we build some further analyses like termination using the covering set
as starting point."

text: A survey of avifauna was carried out in the Mys Shmidta area, north Chukotka,
Russia from 8 June to 12 July 2011. A total of 90 species was recorded in the
area, which together with literature data made a final list of 104 species. For
several species this area is beyond the northern, north-eastern or north-western
limits of their known distribution. We collected new data for 19 globally or locally
threatened species. Tundra Swan Cygnus columbianus, Emperor Goose Anser canagica,
American Golden Plover Pluvialis dominica, Western Sandpiper Calidris mauri, Semipalmated
Sandpiper C. pusilla, Northern House Martin Delichon urbica and Barn Swallow Hirundo
rustica were all confirmed to be breeding. Breeding of Brent Goose Branta bernicla
nigricans, Spectacled Eider Somateria fischeri and Steller's Eider Polysticta
stelleri was judged to be 'very likely'. There was no evidence for breeding of
Ross's Gull Rhodostethia rosea despite several records. Two Eurasian Dotterels
Eudromias morinellus were recorded displaying for the first time in the area,
but the status of the species is unclear. The area is important for Snowy Owl
Nyctea scandiaca, and as moulting grounds for Emperor Goose. Canada Goose Branta
canadensis, Baikal Teal Anas formosa, Bar-tailed Godwit Limosa lapponica, Slaty-backed
Gull Larus schistisagus, Thayer's Gull L. thayeri, Black-headed Gull L. ridibundus,
White-tailed Eagle Haliaeetus albicilla, Steller's Sea Eagle H. pelagicus, Osprey
Pandion haliaetus, Arctic Warbler Phylloscopus borealis and House Sparrow Passer
domesticus are more likely to be rare vagrants or migrants. An observation of
a Pine Siskin Carduelis pinus is the first record for Eurasia.

text: Internal tide driven mixing plays a key role in sustaining the deep ocean
stratification and meridional overturning circulation. Internal tides can be generated
by topographic horizontal scales ranging from hundreds of meters to tens of kilometers.
State of the art topographic products barely resolve scales smaller than ∼10 km
in the deep ocean. On these scales abyssal hills dominate ocean floor roughness.
The impact of abyssal hill roughness on internal‐tide generation is evaluated
in this study. The conversion of M2 barotropic to baroclinic tidal energy is calculated
based on linear wave theory both in real and spectral space using the Shuttle
Radar Topography Mission SRTM30_PLUS bathymetric product at 1/120° resolution
with and without the addition of synthetic abyssal hill roughness. Internal tide
generation by abyssal hills integrates to 0.1 TW globally or 0.03 TW when the
energy flux is empirically corrected for supercritical slope (i.e., ∼10% of the
energy flux due to larger topographic scales resolved in standard products in
both cases). The abyssal hill driven energy conversion is dominated by mid‐ocean
ridges, where abyssal hill roughness is large. Focusing on two regions located
over the Mid‐Atlantic Ridge and the East Pacific Rise, it is shown that regionally
linear theory predicts an increase of the energy flux due to abyssal hills of
up to 100% or 60% when an empirical correction for supercritical slopes is attempted.
Therefore, abyssal hills, unresolved in state of the art topographic products,
can have a strong impact on internal tide generation, especially over mid‐ocean
ridges.

text: "In this study the response of tropical precipitation extremes to warming
in organized convection is examined using a cloud-resolving model. Vertical shear
is imposed to organize the convection into squall lines. Earlier studies show
that in disorganized convection, the fractional increase of precipitation extremes
is similar to that of surface water vapor, which is substantially smaller than
the increase in column water vapor. It has been suggested that organized convection
could lead to stronger amplifications.\r\nRegardless of the strength of the shear,
amplifications of precipitation extremes in the cloud-resolving simulations are
comparable to those of surface water vapor and are substantially less than increases
in column water vapor. The results without shear and with critical shear, for
which the squall lines are perpendicular to the shear, are surprisingly similar
with a fractional rate of increase of precipitation extremes slightly smaller
than that of surface water vapor. Interestingly, the dependence on shear is nonmonotonic,
and stronger supercritical shear yields larger rates, close to or slightly larger
than surface humidity.\r\nA scaling is used to evaluate the thermodynamic and
dynamic contributions to precipitation extreme changes. To first order, they are
dominated by the thermodynamic component, which has the same magnitude for all
shears, close to the change in surface water vapor. The dynamic contribution plays
a secondary role and tends to weaken extremes without shear and with critical
shear, while it strengthens extremes with supercritical shear. These different
dynamic contributions for different shears are due to different responses of convective
mass fluxes in individual updrafts to warming."

text: We introduce a self-propelled colloidal hematite docker that can be steered
to a small particle cargo many times its size, dock, transport the cargo to a
remote location, and then release it. The self-propulsion and docking are reversible
and activated by visible light. The docker can be steered either by a weak uniform
magnetic field or by nanoscale tracks in a textured substrate. The light-activated
motion and docking originate from osmotic/phoretic particle transport in a concentration
gradient of fuel, hydrogen peroxide, induced by the photocatalytic activity of
the hematite. The docking mechanism is versatile and can be applied to various
materials and shapes. The hematite dockers are simple single-component particles
and are synthesized in bulk quantities. This system opens up new possibilities
for designing complex micrometer-size factories as well as new biomimetic systems.

text: Nucleosome remodelers of the DDM1/Lsh family are required for DNA methylation
of transposable elements, but the reason for this is unknown. How DDM1 interacts
with other methylation pathways, such as small-RNA-directed DNA methylation (RdDM),
which is thought to mediate plant asymmetric methylation through DRM enzymes,
is also unclear. Here, we show that most asymmetric methylation is facilitated
by DDM1 and mediated by the methyltransferase CMT2 separately from RdDM. We find
that heterochromatic sequences preferentially require DDM1 for DNA methylation
and that this preference depends on linker histone H1. RdDM is instead inhibited
by heterochromatin and absolutely requires the nucleosome remodeler DRD1. Together,
DDM1 and RdDM mediate nearly all transposon methylation and collaborate to repress
transposition and regulate the methylation and expression of genes. Our results
indicate that DDM1 provides DNA methyltransferases access to H1-containing heterochromatin
to allow stable silencing of transposable elements in cooperation with the RdDM
pathway.

text: Arabidopsis thaliana endosperm, a transient tissue that nourishes the embryo,
exhibits extensive localized DNA demethylation on maternally inherited chromosomes.
Demethylation mediates parent-of-origin–specific (imprinted) gene expression but
is apparently unnecessary for the extensive accumulation of maternally biased
small RNA (sRNA) molecules detected in seeds. Endosperm DNA in the distantly related
monocots rice and maize is likewise locally hypomethylated, but whether this hypomethylation
is generally parent-of-origin specific is unknown. Imprinted expression of sRNA
also remains uninvestigated in monocot seeds. Here, we report high-coverage sequencing
of the Kitaake rice cultivar that enabled us to show that localized hypomethylation
in rice endosperm occurs solely on the maternal genome, preferring regions of
high DNA accessibility. Maternally expressed imprinted genes are enriched for
hypomethylation at putative promoter regions and transcriptional termini and paternally
expressed genes at promoters and gene bodies, mirroring our recent results in
A. thaliana. However, unlike in A. thaliana, rice endosperm sRNA populations are
dominated by specific strong sRNA-producing loci, and imprinted 24-nt sRNAs are
expressed from both parental genomes and correlate with hypomethylation. Overlaps
between imprinted sRNA loci and imprinted genes expressed from opposite alleles
suggest that sRNAs may regulate genomic imprinting. Whereas sRNAs in seedling
tissues primarily originate from small class II (cut-and-paste) transposable elements,
those in endosperm are more uniformly derived, including sequences from other
transposon classes, as well as genic and intergenic regions. Our data indicate
that the endosperm exhibits a unique pattern of sRNA expression and suggest that
localized hypomethylation of maternal endosperm DNA is conserved in flowering
plants.

text: Plants undergo alternation of generation in which reproductive cells develop
in the plant body ("sporophytic generation") and then differentiate into a multicellular
gamete-forming "gametophytic generation." Different populations of helper cells
assist in this transgenerational journey, with somatic tissues supporting early
development and single nurse cells supporting gametogenesis. New data reveal a
two-way relationship between early reproductive cells and their helpers involving
complex epigenetic and signaling networks determining cell number and fate. Later,
the egg cell plays a central role in specifying accessory cells, whereas in both
gametophytes, companion cells contribute non-cell-autonomously to the epigenetic
landscape of the gamete genomes.

text: 'Molecular dynamics simulations of small Cu nanoparticles using three different
interatomic potentials at rising temperature indicate that small nanoparticles
can undergo solid-solid structural transitions through a direct geometrical conversion
route. The direct geometrical conversion can happen for cuboctahedral nanoparticles,
which turn into an icosahedra shape: one diagonal of the square faces contracts,
and the faces are folded along the diagonal to give rise to two equilateral triangles.
The transition is a kinetic process that cannot be fully explained through an
energetic point of view. It has low activation energy and fast reaction time in
the simulations. The transition mechanism is via the transmission of shear waves
initiated from the particle surface and does not involve dislocation activity.'

text: 'Recent studies aimed at investigating artificial analogs of bacterial colonies
have shown that low-density suspensions of self-propelled particles confined in
two dimensions can assemble into finite aggregates that merge and split, but have
a typical size that remains constant (living clusters). In this Letter, we address
the problem of the formation of living clusters and crystals of active particles
in three dimensions. We study two systems: self-propelled particles interacting
via a generic attractive potential and colloids that can move toward each other
as a result of active agents (e.g., by molecular motors). In both cases, fluidlike
“living” clusters form. We explain this general feature in terms of the balance
between active forces and regression to thermodynamic equilibrium. This balance
can be quantified in terms of a dimensionless number that allows us to collapse
the observed clustering behavior onto a universal curve. We also discuss how active
motion affects the kinetics of crystal formation.'

text: 'We study dynamic (1 + ϵ)-approximation algorithms for the all-pairs shortest
paths problem in unweighted undirected n-node m-edge graphs under edge deletions.
The fastest algorithm for this problem is a randomized algorithm with a total
update time of Ȏ(mn) and constant query time by Roditty and Zwick (FOCS 2004).
The fastest deterministic algorithm is from a 1981 paper by Even and Shiloach
(JACM 1981); it has a total update time of O(mn 2 ) and constant query time. We
improve these results as follows: (1) We present an algorithm with a total update
time of Ȏ(n 5/2 ) and constant query time that has an additive error of two in
addition to the 1 + ϵ multiplicative error. This beats the previous Ȏ(mn) time
when m = Ω(n 3/2 ). Note that the additive error is unavoidable since, even in
the static case, an O(n 3-δ )-time (a so-called truly sub cubic) combinatorial
algorithm with 1 + ϵ multiplicative error cannot have an additive error less than
2 - ϵ, unless we make a major breakthrough for Boolean matrix multiplication (Dor,
Halperin and Zwick FOCS 1996) and many other long-standing problems (Vassilevska
Williams and Williams FOCS 2010). The algorithm can also be turned into a (2 +
ϵ)-approximation algorithm (without an additive error) with the same time guarantees,
improving the recent (3 + ϵ)-approximation algorithm with Ȏ(n 5/2+O(1√(log n))
) running time of Bernstein and Roditty (SODA 2011) in terms of both approximation
and time guarantees. (2) We present a deterministic algorithm with a total update
time of Ȏ(mn) and a query time of O(log log n). The algorithm has a multiplicative
error of 1 + ϵ and gives the first improved deterministic algorithm since 1981.
It also answers an open question raised by Bernstein in his STOC 2013 paper. In
order to achieve our results, we introduce two new techniques: (1) A lazy Even-Shiloach
tree algorithm which maintains a bounded-distance shortest-paths tree on a certain
type of emulator called locally persevering emulator. (2) A derandomization technique
based on moving Even-Shiloach trees as a way to derandomize the standard random
set argument. These techniques might be of independent interest.'
