text: Microtubules provide the mechanical force required for chromosome separation
during mitosis. However, little is known about the dynamic (high-frequency) mechanical
properties of microtubules. Here, we theoretically propose to control the vibrations
of a doubly clamped microtubule by tip electrodes and to detect its motion via
the optomechanical coupling between the vibrational modes of the microtubule and
an optical cavity. In the presence of a red-detuned strong pump laser, this coupling
leads to optomechanical-induced transparency of an optical probe field, which
can be detected with state-of-the art technology. The center frequency and line
width of the transparency peak give the resonance frequency and damping rate of
the microtubule, respectively, while the height of the peak reveals information
about the microtubule-cavity field coupling. Our method opens the new possibilities
to gain information about the physical properties of microtubules, which will
enhance our capability to design physical cancer treatment protocols as alternatives
to chemotherapeutic drugs.

text: A d-dimensional simplex S is called a k-reptile (or a k-reptile simplex) if
it can be tiled by k simplices with disjoint interiors that are all mutually congruent
and similar to S. For d = 2, triangular k-reptiles exist for all k of the form
a^2, 3a^2 or a^2+b^2 and they have been completely characterized by Snover, Waiveris,
and Williams. On the other hand, the only k-reptile simplices that are known for
d ≥ 3, have k = m^d, where m is a positive integer. We substantially simplify
the proof by Matoušek and the second author that for d = 3, k-reptile tetrahedra
can exist only for k = m^3. We then prove a weaker analogue of this result for
d = 4 by showing that four-dimensional k-reptile simplices can exist only for
k = m^2.

text: A hippocampal mossy fiber synapse has a complex structure and is implicated
in learning and memory. In this synapse, the mossy fiber boutons attach to the
dendritic shaft by puncta adherentia junctions and wrap around a multiply-branched
spine, forming synaptic junctions. We have recently shown using transmission electron
microscopy, immunoelectron microscopy and serial block face-scanning electron
microscopy that atypical puncta adherentia junctions are formed in the afadin-deficient
mossy fiber synapse and that the complexity of postsynaptic spines and mossy fiber
boutons, the number of spine heads, the area of postsynaptic densities and the
density of synaptic vesicles docked to active zones are decreased in the afadin-deficient
synapse. We investigated here the roles of afadin in the functional differentiations
of the mossy fiber synapse using the afadin-deficient mice. The electrophysiological
studies showed that both the release probability of glutamate and the postsynaptic
responsiveness to glutamate were markedly reduced, but not completely lost, in
the afadin-deficient mossy fiber synapse, whereas neither long-term potentiation
nor long-term depression was affected. These results indicate that afadin plays
roles in the functional differentiations of the presynapse and the postsynapse
of the hippocampal mossy fiber synapse.

text: 'The complex antiferromagnetic orders observed in the honeycomb iridates are
a double-edged sword in the search for a quantum spin-liquid: both attesting that
the magnetic interactions provide many of the necessary ingredients, while simultaneously
impeding access. Focus has naturally been drawn to the unusual magnetic orders
that hint at the underlying spin correlations. However, the study of any particular
broken symmetry state generally provides little clue about the possibility of
other nearby ground states. Here we use magnetic fields approaching 100 Tesla
to reveal the extent of the spin correlations in γ-lithium iridate. We find that
a small component of field along the magnetic easy-axis melts long-range order,
revealing a bistable, strongly correlated spin state. Far from the usual destruction
of antiferromagnetism via spin polarization, the high-field state possesses only
a small fraction of the total iridium moment, without evidence for long-range
order up to the highest attainable magnetic fields.'

text: Magneto-quantum oscillation experiments in high-temperature superconductors
show a strong thermally induced suppression of the oscillation amplitude approaching
the critical dopings [B. J. Ramshaw et al., Science 348, 317 (2014); H. Shishido
et al., Phys. Rev. Lett. 104, 057008 (2010); P. Walmsley et al., Phys. Rev. Lett.
110, 257002 (2013)]—in support of a quantum-critical origin of their phase diagrams.
We suggest that, in addition to a thermodynamic mass enhancement, these experiments
may directly indicate the increasing role of quantum fluctuations that suppress
the quantum oscillation amplitude through inelastic scattering. We show that the
traditional theoretical approaches beyond Lifshitz-Kosevich to calculate the oscillation
amplitude in correlated metals result in a contradiction with the third law of
thermodynamics and suggest a way to rectify this problem.

text: The excitonic insulator phase has long been predicted to form in proximity
to a band gap opening in the underlying band structure. The character of the pairing
is conjectured to crossover from weak (BCS-like) to strong coupling (BEC-like)
as the underlying band structure is tuned from the metallic to the insulating
side of the gap opening. Here we report the high-magnetic field phase diagram
of graphite to exhibit just such a crossover. By way of comprehensive angle-resolved
magnetoresistance measurements, we demonstrate that the underlying band gap opening
occurs inside the magnetic field-induced phase, paving the way for a systematic
study of the BCS-BEC-like crossover by means of conventional condensed matter
probes.

text: Broken fourfold rotational (C4) symmetry is observed in the experimental properties
of several classes of unconventional superconductors. It has been proposed that
this symmetry breaking is important for superconducting pairing in these materials,
but in the high-Tc cuprates this broken symmetry has never been observed on the
Fermi surface. Here we report a pronounced anisotropy in the angle dependence
of the interlayer magnetoresistance of the underdoped high transition temperature
(high-Tc) superconductor YBa2Cu3O6.58, directly revealing broken C4 symmetry on
the Fermi surface. Moreover, we demonstrate that this Fermi surface has C2 symmetry
of the type produced by a uniaxial or anisotropic density-wave phase. This establishes
the central role of C4 symmetry breaking in the Fermi surface reconstruction of
YBa2Cu3O6+δ , and suggests a striking degree of universality among unconventional
superconductors.

text: 'In the developing and adult brain, oligodendrocyte precursor cells (OPCs)
are influenced by neuronal activity: they are involved in synaptic signaling with
neurons, and their proliferation and differentiation into myelinating glia can
be altered by transient changes in neuronal firing. An important question that
has been unanswered is whether OPCs can discriminate different patterns of neuronal
activity and respond to them in a distinct way. Here, we demonstrate in brain
slices that the pattern of neuronal activity determines the functional changes
triggered at synapses between axons and OPCs. Furthermore, we show that stimulation
of the corpus callosum at different frequencies in vivo affects proliferation
and differentiation of OPCs in a dissimilar way. Our findings suggest that neurons
do not influence OPCs in “all-or-none” fashion but use their firing pattern to
tune the response and behavior of these nonneuronal cells.'

text: Adipose tissues play key roles in energy homeostasis. Brown adipocytes and
beige adipocytes in white adipose tissue (WAT) share the similar characters of
thermogenesis, both of them could be potential targets for obesity management.
Several thermo-sensitive transient receptor potential channels (thermoTRPs) are
shown to be involved in adipocyte biology. However, the expression pattern of
thermoTRPs in adipose tissues from obese mice is still unknown. The mRNA expression
of thermoTRPs in subcutaneous WAT (sWAT) and interscapular brown adipose tissue
(iBAT) from lean and obese mice were measured using reverse transcriptase-quantitative
PCRs (RT-qPCR). The results demonstrated that all 10 thermoTRPs are expressed
in both iBAT and sWAT, and without significant difference in the mRNA expression
level of thermoTRPs between these two tissues. Moreover, Trpv1 and Trpv3 mRNA
expression levels in both iBAT and sWAT were significantly decreased in high fat
diet (HFD)-induced obese mice and db/db (leptin receptor deficient) mice. Trpm2
mRNA expression level was significantly decreased only in sWAT from HFD-induced
obese mice and db/db mice. On the other hand, Trpv2 and Trpv4 mRNA expression
levels in iBAT and sWAT were significantly increased in HFD-induced obese mice
and db/db mice. Taken together, we conclude that all 10 thermoTRPs are expressed
in iBAT and sWAT. And several thermoTRPs differentially expressed in adipose tissues
from HFD-induced obese mice and db/db mice, suggesting a potential involvement
in anti-obesity regulations.

text: 'We revisit the problem of estimating entropy of discrete distributions from
independent samples, studied recently by Acharya, Orlitsky, Suresh and Tyagi (SODA
2015), improving their upper and lower bounds on the necessary sample size n.
For estimating Renyi entropy of order alpha, up to constant accuracy and error
probability, we show the following * Upper bounds n = O(1) 2^{(1-1/alpha)H_alpha}
for integer alpha>1, as the worst case over distributions with Renyi entropy
equal to H_alpha. * Lower bounds n = Omega(1) K^{1-1/alpha} for any real alpha>1,
with the constant being an inverse polynomial of the accuracy, as the worst case
over all distributions on K elements. Our upper bounds essentially replace the
alphabet size by a factor exponential in the entropy, which offers improvements
especially in low or medium entropy regimes (interesting for example in anomaly
detection). As for the lower bounds, our proof explicitly shows how the complexity
depends on both alphabet and accuracy, partially solving the open problem posted
in previous works. The argument for upper bounds derives a clean identity for
the variance of falling-power sum of a multinomial distribution. Our approach
for lower bounds utilizes convex optimization to find a distribution with possibly
worse estimation performance, and may be of independent interest as a tool to
work with Le Cam’s two point method. '

text: Nested weighted automata (NWA) present a robust and convenient automata-theoretic
formalism for quantitative specifications. Previous works have considered NWA
that processed input words only in the forward direction. It is natural to allow
the automata to process input words backwards as well, for example, to measure
the maximal or average time between a response and the preceding request. We therefore
introduce and study bidirectional NWA that can process input words in both directions.
First, we show that bidirectional NWA can express interesting quantitative properties
that are not expressible by forward-only NWA. Second, for the fundamental decision
problems of emptiness and universality, we establish decidability and complexity
results for the new framework which match the best-known results for the special
case of forward-only NWA. Thus, for NWA, the increased expressiveness of bidirectionality
is achieved at no additional computational complexity. This is in stark contrast
to the unweighted case, where bidirectional finite automata are no more expressive
but exponentially more succinct than their forward-only counterparts.

text: 'We establish a weak–strong uniqueness principle for solutions to entropy-dissipating
reaction–diffusion equations: As long as a strong solution to the reaction–diffusion
equation exists, any weak solution and even any renormalized solution must coincide
with this strong solution. Our assumptions on the reaction rates are just the
entropy condition and local Lipschitz continuity; in particular, we do not impose
any growth restrictions on the reaction rates. Therefore, our result applies to
any single reversible reaction with mass-action kinetics as well as to systems
of reversible reactions with mass-action kinetics satisfying the detailed balance
condition. Renormalized solutions are known to exist globally in time for reaction–diffusion
equations with entropy-dissipating reaction rates; in contrast, the global-in-time
existence of weak solutions is in general still an open problem–even for smooth
data–, thereby motivating the study of renormalized solutions. The key ingredient
of our result is a careful adjustment of the usual relative entropy functional,
whose evolution cannot be controlled properly for weak solutions or renormalized
solutions.'

text: To determine the dynamics of allelic-specific expression during mouse development,
we analyzed RNA-seq data from 23 F1 tissues from different developmental stages,
including 19 female tissues allowing X chromosome inactivation (XCI) escapers
to also be detected. We demonstrate that allelic expression arising from genetic
or epigenetic differences is highly tissue-specific. We find that tissue-specific
strain-biased gene expression may be regulated by tissue-specific enhancers or
by post-transcriptional differences in stability between the alleles. We also
find that escape from X-inactivation is tissue-specific, with leg muscle showing
an unexpectedly high rate of XCI escapers. By surveying a range of tissues during
development, and performing extensive validation, we are able to provide a high
confidence list of mouse imprinted genes including 18 novel genes. This shows
that cluster size varies dynamically during development and can be substantially
larger than previously thought, with the Igf2r cluster extending over 10 Mb in
placenta.

text: Background HIV-1 infection and drug abuse are frequently co-morbid and their
association greatly increases the severity of HIV-1-induced neuropathology. While
nucleus accumbens (NAcc) function is severely perturbed by drugs of abuse, little
is known about how HIV-1 infection affects NAcc. Methods We used calcium and voltage
imaging to investigate the effect of HIV-1 trans-activator of transcription (Tat)
on rat NAcc. Based on previous neuronal studies, we hypothesized that Tat modulates
intracellular Ca2+ homeostasis of NAcc neurons. Results We provide evidence that
Tat triggers a Ca2+ signaling cascade in NAcc medium spiny neurons (MSN) expressing
D1-like dopamine receptors leading to neuronal depolarization. Firstly, Tat induced
inositol 1,4,5-trisphsophate (IP3) receptor-mediated Ca2+ release from endoplasmic
reticulum, followed by Ca2+ and Na+ influx via transient receptor potential canonical
channels. The influx of cations depolarizes the membrane promoting additional
Ca2+ entry through voltage-gated P/Q-type Ca2+ channels and opening of tetrodotoxin-sensitive
Na+ channels. By activating this mechanism, Tat elicits a feed-forward depolarization
increasing the excitability of D1-phosphatidylinositol-linked NAcc MSN. We previously
found that cocaine targets NAcc neurons directly (independent of the inhibition
of dopamine transporter) only when IP3-generating mechanisms are concomitantly
initiated. When tested here, cocaine produced a dose-dependent potentiation of
the effect of Tat on cytosolic Ca2+. Conclusion We describe for the first time
a HIV-1 Tat-triggered Ca2+ signaling in MSN of NAcc involving TRPC and depolarization
and a potentiation of the effect of Tat by cocaine, which may be relevant for
the reward axis in cocaine-abusing HIV-1-positive patients.

text: 'We study probabilistic models of natural images and extend the autoregressive
family of PixelCNN models by incorporating latent variables. Subsequently, we
describe two new generative image models that exploit different image transformations
as latent variables: a quantized grayscale view of the image or a multi-resolution
image pyramid. The proposed models tackle two known shortcomings of existing PixelCNN
models: 1) their tendency to focus on low-level image details, while largely ignoring
high-level image information, such as object shapes, and 2) their computationally
costly procedure for image sampling. We experimentally demonstrate benefits of
our LatentPixelCNN models, in particular showing that they produce much more realistically
looking image samples than previous state-of-the-art probabilistic models. '

text: We present a computational approach for designing CurveUps, curvy shells that
form from an initially flat state. They consist of small rigid tiles that are
tightly held together by two pre-stretched elastic sheets attached to them. Our
method allows the realization of smooth, doubly curved surfaces that can be fabricated
as a flat piece. Once released, the restoring forces of the pre-stretched sheets
support the object to take shape in 3D. CurveUps are structurally stable in their
target configuration. The design process starts with a target surface. Our method
generates a tile layout in 2D and optimizes the distribution, shape, and attachment
areas of the tiles to obtain a configuration that is fabricable and in which the
curved up state closely matches the target. Our approach is based on an efficient
approximate model and a local optimization strategy for an otherwise intractable
nonlinear optimization problem. We demonstrate the effectiveness of our approach
for a wide range of shapes, all realized as physical prototypes.

text: " We present an interactive design system to create functional mechanical
\ objects. Our computational approach allows novice users to retarget an existing
mechanical template to a user-specified input shape. Our proposed representation
for a mechanical template encodes a parameterized mechanism, mechanical constraints
that ensure a physically valid configuration, spatial relationships of mechanical
parts to the user-provided shape, and functional constraints that specify an intended
functionality. We provide an intuitive interface and optimization-in-the-loop
approach for finding a valid configuration of the mechanism and the shape to
ensure that higher-level functional goals are met. Our algorithm interactively
optimizes the mechanism while the user manipulates the placement of mechanical
components and the shape. Our system allows users to efficiently explore various
design choices and to synthesize customized mechanical objects that can be fabricated
with rapid prototyping technologies. We demonstrate the efficacy of our approach
by retargeting various mechanical templates to different shapes and fabricating
the resulting functional mechanical objects.\r\n"

text: Network games (NGs) are played on directed graphs and are extensively used
in network design and analysis. Search problems for NGs include finding special
strategy profiles such as a Nash equilibrium and a globally optimal solution.
The networks modeled by NGs may be huge. In formal verification, abstraction has
proven to be an extremely effective technique for reasoning about systems with
big and even infinite state spaces. We describe an abstraction-refinement methodology
for reasoning about NGs. Our methodology is based on an abstraction function that
maps the state space of an NG to a much smaller state space. We search for a global
optimum and a Nash equilibrium by reasoning on an under- and an overapproximation
defined on top of this smaller state space. When the approximations are too coarse
to find such profiles, we refine the abstraction function. Our experimental results
demonstrate the efficiency of the methodology.
