text: "LCLs or locally checkable labelling problems (e.g. maximal independent set,
maximal matching, and vertex colouring) in the LOCAL model of computation are
very well-understood in cycles (toroidal 1-dimensional grids): every problem has
a complexity of O(1), Θ(log* n), or Θ(n), and the design of optimal algorithms
can be fully automated. This work develops the complexity theory of LCL problems
for toroidal 2-dimensional grids. The complexity classes are the same as in the
1-dimensional case: O(1), Θ(log* n), and Θ(n). However, given an LCL problem it
is undecidable whether its complexity is Θ(log* n) or Θ(n) in 2-dimensional grids.\r\nNevertheless,
if we correctly guess that the complexity of a problem is Θ(log* n), we can completely
automate the design of optimal algorithms. For any problem we can find an algorithm
that is of a normal form A' o Sk, where A' is a finite function, Sk is an algorithm
for finding a maximal independent set in kth power of the grid, and k is a constant.\r\nFinally,
partially with the help of automated design tools, we classify the complexity
of several concrete LCL problems related to colourings and orientations."

text: A change regarding the extent of adhesion - hereafter referred to as adhesion
plasticity - between adhesive and less-adhesive states of mammalian cells is important
for their behavior. To investigate adhesion plasticity, we have selected a stable
isogenic subpopulation of human MDA-MB-468 breast carcinoma cells growing in suspension.
These suspension cells are unable to re-adhere to various matrices or to contract
three-dimensional collagen lattices. By using transcriptome analysis, we identified
the focal adhesion protein tensin3 (Tns3) as a determinant of adhesion plasticity.
Tns3 is strongly reduced at mRNA and protein levels in suspension cells. Furthermore,
by transiently challenging breast cancer cells to grow under non-adherent conditions
markedly reduces Tns3 protein expression, which is regained upon re-adhesion.
Stable knockdown of Tns3 in parental MDA-MB-468 cells results in defective adhesion,
spreading and migration. Tns3-knockdown cells display impaired structure and dynamics
of focal adhesion complexes as determined by immunostaining. Restoration of Tns3
protein expression in suspension cells partially rescues adhesion and focal contact
composition. Our work identifies Tns3 as a crucial focal adhesion component regulated
by, and functionally contributing to, the switch between adhesive and non-adhesive
states in MDA-MB-468 cancer cells.

text: It has been known since Stefan Vogel's observations in 1969 that solitary
female oil bees collect fatty floral oils from specialized oil-secreting plants
with the aid of hairy patches on either their legs or abdomen, a reward used as
food for their larvae and/or to line their brood cells. Similar adaptations are
also known from male oil bees, although the purpose of their oil-collecting behavior
has not yet been clarified. Here, we describe a novel pollination system involving
male Paratetrapedia oil bees and the tropical herb Anthurium acutifolium. We present
ultrastructural morphological details of bee and plant structures involved in
this interaction and the composition of floral scents likely mediating pollinator
attraction. Inflorescences of A. acutifolium were visited almost exclusively by
male P. chocoensis oil bees. The bees mopped with a hairy patch of their abdominal
sterna 3 across the inflorescence surface. During this activity on both staminate
and pistillate stage inflorescences, bees’ abdomens and legs became loaded with
pollen and contacted receptive stigmas. In contrast to what has been observed
in other angiosperms visited for the collection of fatty floral oils, the inflorescences/flowers
of A. acutifolium do not have structures specialized in oil secretion, i.e., elaiophores.
These inflorescences, nonetheless, were strongly scented during the time interval
they were visited by the bees. Gas chromatography/mass spectrometry (GC/MS) analyses
of dynamic headspace floral samples revealed that inflorescences of both anthetic
phases emitted scent bouquets consisting mainly of aliphatic esters, indole and
uncommmon terpenoids (megastigmanes). Interestingly enough, our data suggest that
the unusual floral scent of A. acutifolium is a perfume reward collected by male
P. chocoensis oil bees. This pollination system thus bears a remarkable resemblence
with the interactions between perfume-collecting male euglossine bees and their
preferred flowers, discovered by Stefan Vogel half a century ago.

text: Mutator strains are expected to evolve when the availability and effect of
beneficial mutations are high enough to counteract the disadvantage from deleterious
mutations that will inevitably accumulate. As the population becomes more adapted
to its environment, both availability and effect of beneficial mutations necessarily
decrease and mutation rates are predicted to decrease. It has been shown that
certain molecular mechanisms can lead to increased mutation rates when the organism
finds itself in a stressful environment. While this may be a correlated response
to other functions, it could also be an adaptive mechanism, raising mutation rates
only when it is most advantageous. Here, we use a mathematical model to investigate
the plausibility of the adaptive hypothesis. We show that such a mechanism can
be mantained if the population is subjected to diverse stresses. By simulating
various antibiotic treatment schemes, we find that combination treatments can
reduce the effectiveness of second-order selection on stress-induced mutagenesis.
We discuss the implications of our results to strategies of antibiotic therapy.

text: 'De, Trevisan and Tulsiani [CRYPTO 2010] show that every distribution over
n-bit strings which has constant statistical distance to uniform (e.g., the output
of a pseudorandom generator mapping n-1 to n bit strings), can be distinguished
from the uniform distribution with advantage epsilon by a circuit of size O( 2^n
epsilon^2). We generalize this result, showing that a distribution which has less
than k bits of min-entropy, can be distinguished from any distribution with k
bits of delta-smooth min-entropy with advantage epsilon by a circuit of size O(2^k
epsilon^2/delta^2). As a special case, this implies that any distribution with
support at most 2^k (e.g., the output of a pseudoentropy generator mapping k to
n bit strings) can be distinguished from any given distribution with min-entropy
k+1 with advantage epsilon by a circuit of size O(2^k epsilon^2). Our result thus
shows that pseudoentropy distributions face basically the same non-uniform attacks
as pseudorandom distributions. '

text: 'Extracellular matrix signals from the microenvironment regulate gene expression
patterns and cell behavior. Using a combination of experiments and geometric models,
we demonstrate correlations between cell geometry, three-dimensional (3D) organization
of chromosome territories, and gene expression. Fluorescence in situ hybridization
experiments showed that micropatterned fibroblasts cultured on anisotropic versus
isotropic substrates resulted in repositioning of specific chromosomes, which
contained genes that were differentially regulated by cell geometries. Experiments
combined with ellipsoid packing models revealed that the mechanosensitivity of
chromosomes was correlated with their orientation in the nucleus. Transcription
inhibition experiments suggested that the intermingling degree was more sensitive
to global changes in transcription than to chromosome radial positioning and its
orientations. These results suggested that cell geometry modulated 3D chromosome
arrangement, and their neighborhoods correlated with gene expression patterns
in a predictable manner. This is central to understanding geometric control of
genetic programs involved in cellular homeostasis and the associated diseases. '

text: 'In antagonistic symbioses, such as host–parasite interactions, one population’s
success is the other’s loss. In mutualistic symbioses, such as division of labor,
both parties can gain, but they might have different preferences over the possible
mutualistic arrangements. The rates of evolution of the two populations in a symbiosis
are important determinants of which population will be more successful: Faster
evolution is thought to be favored in antagonistic symbioses (the “Red Queen effect”),
but disfavored in certain mutualistic symbioses (the “Red King effect”). However,
it remains unclear which biological parameters drive these effects. Here, we analyze
the effects of the various determinants of evolutionary rate: generation time,
mutation rate, population size, and the intensity of natural selection. Our main
results hold for the case where mutation is infrequent. Slower evolution causes
a long-term advantage in an important class of mutualistic interactions. Surprisingly,
less intense selection is the strongest driver of this Red King effect, whereas
relative mutation rates and generation times have little effect. In antagonistic
interactions, faster evolution by any means is beneficial. Our results provide
insight into the demographic evolution of symbionts. '

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: 'How the organization of genes on a chromosome shapes adaptation is essential
for understanding evolutionary paths. Here, we investigate how adaptation to rapidly
increasing levels of antibiotic depends on the chromosomal neighborhood of a drug-resistance
gene inserted at different positions of the Escherichia coli chromosome. Using
a dual-fluorescence reporter that allows us to distinguish gene amplifications
from other up-mutations, we track in real-time adaptive changes in expression
of the drug-resistance gene. We find that the relative contribution of several
mutation types differs systematically between loci due to properties of neighboring
genes: essentiality, expression, orientation, termination, and presence of duplicates.
These properties determine rate and fitness effects of gene amplification, deletions,
and mutations compromising transcriptional termination. Thus, the adaptive potential
of a gene under selection is a system-property with a complex genetic basis that
is specific for each chromosomal locus, and it can be inferred from detailed functional
and genomic data.'

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

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. '
