are introduction of NMS (Non-Maximum Suppression) and double thresholding of \r\nthe

classical Canny’s edge detection algorithm. The results show that our algorithm
works significantly well on different benchmark images as well as medical images
(hand radiography images). "

text: The human Mediator complex controls RNA polymerase II (pol II) function in
ways that remain incompletely understood. Activator-Mediator binding alters Mediator
structure, and these activator-induced structural shifts appear to play key roles
in regulating transcription. A recent cryo-electron microscopy (EM) analysis revealed
that pol II adopted a stable orientation within a Mediator-pol II-TFIIF assembly
in which Mediator was bound to the activation domain of viral protein 16 (VP16).
Whereas TFIIF was shown to be important for orienting pol II within this assembly,
the potential role of the activator was not assessed. To determine how activator
binding might affect pol II orientation, we isolated human Mediator-pol II-TFIIF
complexes in which Mediator was not bound to an activator. Cryo-EM analysis of
this assembly, coupled with pol II crystal structure docking, revealed that pol
II binds Mediator at the same general location; however, in contrast to VP16-bound
Mediator, pol II does not appear to stably orient in the absence of an activator.
Variability in pol II orientation might be important mechanistically, perhaps
to enable sense and antisense transcription at human promoters. Because Mediator
interacts extensively with pol II, these results suggest that Mediator structural
shifts induced by activator binding help stably orient pol II prior to transcription
initiation.

text: Tonic receptors convey stimulus duration and intensity and are implicated
in homeostatic control. However, how tonic homeostatic signals are generated and
how they reconfigure neural circuits and modify animal behavior is poorly understood.
Here we show that Caenorhabditis elegans O2-sensing neurons are tonic receptors
that continuously signal ambient [O2] to set the animal's behavioral state. Sustained
signaling relied on a Ca2+ relay involving L-type voltage-gated Ca2+ channels,
the ryanodine and the inositol-1,4,5-trisphosphate receptors. Tonic activity evoked
continuous neuropeptide release, which helps elicit the enduring behavioral state
associated with high [O2]. Sustained O2 receptor signaling was propagated to downstream
neural circuits, including the hub interneuron RMG. O2 receptors evoked similar
locomotory states at particular O2 concentrations, regardless of previous d[O2]/dt.
However, a phasic component of the URX receptors' response to high d[O2]/dt, as
well as tonic-to-phasic transformations in downstream interneurons, enabled transient
reorientation movements shaped by d[O2]/dt. Our results highlight how tonic homeostatic
signals can generate both transient and enduring behavioral change.

In the living cell, proteins are able to organize space much larger than their dimensions. In return, changes of intracellular space can influence biochemical reactions, allowing cells to sense their size and shape. Despite the possibility to reconstitute protein self-organization with only a few purified components, we still lack knowledge of how geometrical boundaries affect spatiotemporal protein patterns. Following a minimal systems approach, we used purified proteins and photolithographically patterned membranes to study the influence of spatial confinement on the self-organization of the Min system, a spatial regulator of bacterial cytokinesis, in vitro. We found that the emerging protein pattern responds even to the lateral, two-dimensional geometry of the membrane such that, as in the three-dimensional cell, Min protein waves travel along the longest axis of the membrane patch. This shows that for spatial sensing the Min system does not need to be enclosed in a three-dimensional compartment. Using a computational model we quantitatively analyzed our experimental findings and identified persistent binding of MinE to the membrane as requirement for the Min system to sense geometry. Our results give insight into the interplay between geometrical confinement and biochemical patterns emerging from a nonlinear reaction-diffusion system.

text: 'Background: Drosophila albomicans is a unique model organism for studying
both sex chromosome and B chromosome evolution. A pair of its autosomes comprising
roughly 40% of the whole genome has fused to the ancient X and Y chromosomes only
about 0.12 million years ago, thereby creating the youngest and most gene-rich
neo-sex system reported to date. This species also possesses recently derived
B chromosomes that show non-Mendelian inheritance and significantly influence
fertility.Methods: We sequenced male flies with B chromosomes at 124.5-fold genome
coverage using next-generation sequencing. To characterize neo-Y specific changes
and B chromosome sequences, we also sequenced inbred female flies derived from
the same strain but without B''s at 28.5-fold.Results: We assembled a female genome
and placed 53% of the sequence and 85% of the annotated proteins into specific
chromosomes, by comparison with the 12 Drosophila genomes. Despite its very recent
origin, the non-recombining neo-Y chromosome shows various signs of degeneration,
including a significant enrichment of non-functional genes compared to the neo-X,
and an excess of tandem duplications relative to other chromosomes. We also characterized
a B-chromosome linked scaffold that contains an actively transcribed unit and
shows sequence similarity to the subcentromeric regions of both the ancient X
and the neo-X chromosome.Conclusions: Our results provide novel insights into
the very early stages of sex chromosome evolution and B chromosome origination,
and suggest an unprecedented connection between the births of these two systems
in D. albomicans.'

text: We introduce an algorithm and representation for fabricating 3D shape abstractions
using mutually intersecting planar cut-outs. The planes have prefabricated slits
at their intersections and are assembled by sliding them together. Often such
abstractions are used as a sculptural art form or in architecture and are colloquially
called ‘cardboard sculptures’. Based on an analysis of construction rules, we
propose an extended binary space partitioning tree as an efficient representation
of such cardboard models which allows us to quickly evaluate the feasibility of
newly added planar elements. The complexity of insertion order quickly increases
with the number of planar elements and manual analysis becomes intractable. We
provide tools for generating cardboard sculptures with guaranteed constructibility.
In combination with a simple optimization and sampling strategy for new elements,
planar shape abstraction models can be designed by iteratively adding elements.
As an output, we obtain a fabrication plan that can be printed or sent to a laser
cutter. We demonstrate the complete process by designing and fabricating cardboard
models of various well-known 3D shapes.

text: We report numerical simulations of membrane tubulation driven by large colloidal
particles. Using Monte Carlo simulations we study how the process depends on particle
size and binding strength, and present accurate free energy calculations to sort
out how tube formation compares with the competing budding process. We find that
tube formation is a result of the collective behavior of the particles adhering
on the surface, and it occurs for binding strengths that are smaller than those
required for budding. We also find that long linear aggregates of particles forming
on the membrane surface act as nucleation seeds for tubulation by lowering the
free energy barrier associated to the process.

text: Using computer simulations, we show that lipid membranes can mediate linear
aggregation of spherical nanoparticles binding to it for a wide range of biologically
relevant bending rigidities. This result is in net contrast with the isotropic
aggregation of nanoparticles on fluid interfaces or the expected clustering of
isotropic insertions in biological membranes. We present a phase diagram indicating
where linear aggregation is expected and compute explicitly the free-energy barriers
associated with linear and isotropic aggregation. Finally, we provide simple scaling
arguments to explain this phenomenology.

text: In July, 2011, a 32-year-old man presented with thoracic pain radiating to
the left arm and upper dorsum, shortness of breath, and palpitations. He had had
upper back tension for 6 months. Medical history was unremarkable apart from moderate
nicotine use (two pack-years). Echocardiography, electrocardiography, and laboratory
tests were unremarkable, excluding a cardiac event. CT of the chest after chest
radiography showed a large bulla of 16 cm diameter in the right hemithorax (figure
A). We did not detect radiological evidence of underlying pulmonary disease. The
bulla wall was unremarkable and no structures were seen within the bulla.

text: We prepare and study a metastable attractive Mott-insulator state formed with
bosonic atoms in a three-dimensional optical lattice. Starting from a Mott insulator
with Cs atoms at weak repulsive interactions, we use a magnetic Feshbach resonance
to tune the interactions to large attractive values and produce a metastable state
pinned by attractive interactions with a lifetime on the order of 10 s. We probe
the (de)excitation spectrum via lattice modulation spectroscopy, measuring the
interaction dependence of two- and three-body bound-state energies. As a result
of increased on-site three-body loss we observe resonance broadening and suppression
of tunneling processes that produce three-body occupation.

text: The goal of this work is to study the superconducting coherence length in
the fluctuation regime in cuprate superconductors. In this work we present cantilever
torque magnetometry measurements of micron-size BSCCO flakes patterned with arrays
of nanometer scale rings or holes. Using ultrasensitive dynamic torque magnetometry,
oscillations in magnetization are observed near Tc as a function of the applied
magnetic flux threading the array. Special effort was made to detect the oscillations
in magnetization at temperatures above Tc, where the Nernst effect and magnetization
measurements suggest the possibility of pairing. To constrain the magnitude of
the coherence length in the fluctuation regime, we will present the dependence
of the amplitude of the h/2e period oscillations as a function of temperature
and hole size.

text: Decades of research in distributed computing have led to a variety of perspectives
on what it means for a concurrent algorithm to be efficient, depending on model
assumptions, progress guarantees, and complexity metrics. It is therefore natural
to ask whether one could compose algorithms that perform efficiently under different
conditions, so that the composition preserves the performance of the original
components when their conditions are met. In this paper, we evaluate the cost
of composing shared-memory algorithms. First, we formally define the notion of
safely composable algorithms and we show that every sequential type has a safely
composable implementation, as long as enough state is transferred between modules.
Since such generic implementations are inherently expensive, we present a more
general light-weight specification that allows the designer to transfer very little
state between modules, by taking advantage of the semantics of the implemented
object. Using this framework, we implement a composed longlived test-and-set object,
with the property that each of its modules is asymptotically optimal with respect
to the progress condition it ensures, while the entire implementation only uses
objects with consensus number at most two. Thus, we show that the overhead of
composition can be negligible in the case of some important shared-memory abstractions.

text: Renaming is a fundamental problem in distributed computing, in which a set
of n processes need to pick unique names from a namespace of limited size. In
this paper, we present the first early-deciding upper bounds for synchronous renaming,
in which the running time adapts to the actual number of failures f in the execution.
We show that, surprisingly, renaming can be solved in constant time if the number
of failures f is limited to O(√n), while for general f ≤ n - 1 renaming can always
be solved in O(log f) communication rounds. In the wait-free case, i.e. for f
= n - 1, our upper bounds match the Ω(log n) lower bound of Chaudhuri et al. [13].

text: Set agreement is a fundamental problem in distributed computing in which processes
collectively choose a small subset of values from a larger set of proposals. The
impossibility of fault-tolerant set agreement in asynchronous networks is one
of the seminal results in distributed computing. In synchronous networks, too,
the complexity of set agreement has been a significant research challenge that
has now been resolved. Real systems, however, are neither purely synchronous nor
purely asynchronous. Rather, they tend to alternate between periods of synchrony
and periods of asynchrony. Nothing specific is known about the complexity of set
agreement in such a "partially synchronous" setting. In this paper,
we address this challenge, presenting the first (asymptotically) tight bound on
the complexity of set agreement in such systems. We introduce a novel technique
for simulating, in a fault-prone asynchronous shared memory, executions of an
asynchronous and failure-prone message-passing system in which some fragments
appear synchronous to some processes. We use this simulation technique to derive
a lower bound on the round complexity of set agreement in a partially synchronous
system by a reduction from asynchronous wait-free set agreement. Specifically,
we show that every set agreement protocol requires at least $\lfloor\frac t k
\rfloor + 2$ synchronous rounds to decide. We present an (asymptotically) matching
algorithm that relies on a distributed asynchrony detection mechanism to decide
as soon as possible during periods of synchrony. From these two results, we derive
the size of the minimal window of synchrony needed to solve set agreement. By
relating synchronous, asynchronous and partially synchronous environments, our
simulation technique is of independent interest. In particular, it allows us to
obtain a new lower bound on the complexity of early deciding k-set agreement complementary
to that of Gafni et al. (in SIAM J. Comput. 40(1):63-78, 2011), and to re-derive
the combinatorial topology lower bound of Guerraoui et al. (in Theor. Comput.
Sci. 410(6-7):570-580, 2009) in an algorithmic way.

text: 'Asynchronous task allocation is a fundamental problem in distributed computing
in which p asynchronous processes must execute a set of m tasks. Also known as
write-all or do-all, this problem been studied extensively, both independently
and as a key building block for various distributed algorithms. In this paper,
we break new ground on this classic problem: we introduce the To-Do Tree concurrent
data structure, which improves on the best known randomized and deterministic
upper bounds. In the presence of an adaptive adversary, the randomized To-Do Tree
algorithm has O(m + p log p log2 m) work complexity. We then show that there exists
a deterministic variant of the To-Do Tree algorithm with work complexity O(m +
p log5 m log2 max(m, p)). For all values of m and p, our algorithms are within
log factors of the Ω(m + p log p) lower bound for this problem. The key technical
ingredient in our results is a new approach for analyzing concurrent executions
against a strong adaptive scheduler. This technique allows us to handle the complex
dependencies between the processes'' coin flips and their scheduling, and to tightly
bound the work needed to perform subsets of the tasks.'

text: Synchronous distributed algorithms are easier to design and prove correct
than algorithms that tolerate asynchrony. Yet, in the real world, networks experience
asynchrony and other timing anomalies. In this paper, we address the question
of how to efficiently transform an algorithm that relies on synchronous timing
into an algorithm that tolerates asynchronous executions. We introduce a transformation
technique from synchronous algorithms to indulgent algorithms (Guerraoui, in PODC,
pp. 289-297, 2000), which induces only a constant overhead in terms of time complexity
in well-behaved executions. Our technique is based on a new abstraction we call
an asynchrony detector, which the participating processes implement collectively.
The resulting transformation works for the class of colorless distributed tasks,
including consensus and set agreement. Interestingly, we also show that our technique
is relevant for colored tasks, by applying it to the renaming problem, to obtain
the first indulgent renaming algorithm.

text: Female mate choice acts as an important evolutionary force, yet the influence
of the environment on both its expression and the selective pressures acting upon
it remains unknown. We found consistent heritable differences between females
in their choice of mate based on ornament size during a 25‐year study of a population
of collared flycatchers. However, the fitness consequences of mate choice were
dependent on environmental conditions experienced whilst breeding. Females breeding
with highly ornamented males experienced high relative fitness during dry summer
conditions, but low relative fitness during wetter years. Our results imply that
sexual selection within a population can be highly variable and dependent upon
the prevailing weather conditions experienced by individuals.

text: Although studies on laboratory species and natural populations of vertebrates
have shown reproduction to impair later performance, little is known of the age‐specific
associations between reproduction and survival, and how such findings apply to
the ageing of large, long‐lived species. Herein we develop a framework to examine
population‐level patterns of reproduction and survival across lifespan in long‐lived
organisms, and decompose those changes into individual‐level effects, and the
effects of age‐specific trade‐offs between fitness components. We apply this to
an extensive longitudinal dataset on female semi‐captive Asian timber elephants
(Elephas maximus) and report the first evidence of age‐specific fitness declines
that are driven by age‐specific associations between fitness components in a long‐lived
mammal. Associations between reproduction and survival are positive in early life,
but negative in later life with up to 71% of later‐life survival declines associated
with investing in the production of offspring within this population of this critically
endangered species.

text: We present an analysis of finite-size effects in jammed packings of N soft,
frictionless spheres at zero temperature. There is a 1/N correction to the discrete
jump in the contact number at the transition so that jammed packings exist only
above isostaticity. As a result, the canonical power-law scalings of the contact
number and elastic moduli break down at low pressure. These quantities exhibit
scaling collapse with a nontrivial scaling function, demonstrating that the jamming
transition can be considered a phase transition. Scaling is achieved as a function
of N in both two and three dimensions, indicating an upper critical dimension
of 2.

text: Fungal cell walls frequently contain a polymer of mannose and galactose called
galactomannan. In the pathogenic filamentous fungus Aspergillus fumigatus, this
polysaccharide is made of a linear mannan backbone with side chains of galactofuran
and is anchored to the plasma membrane via a glycosylphosphatidylinositol or is
covalently linked to the cell wall. To date, the biosynthesis and significance
of this polysaccharide are unknown. The present data demonstrate that deletion
of the Golgi UDP-galactofuranose transporter GlfB or the GDP-mannose transporter
GmtA leads to the absence of galactofuran or galactomannan, respectively. This
indicates that the biosynthesis of galactomannan probably occurs in the lumen
of the Golgi apparatus and thus contrasts with the biosynthesis of other fungal
cell wall polysaccharides studied to date that takes place at the plasma membrane.
Transglycosylation of galactomannan from the membrane to the cell wall is hypothesized
because both the cell wall-bound and membrane-bound polysaccharide forms are affected
in the generated mutants. Considering the severe growth defect of the A. fumigatus
GmtA-deficient mutant, proving this paradigm might provide new targets for antifungal
therapy.
