text: Behavioural variation among conspecifics is typically contingent on individual
state or environmental conditions. Sex-specific genetic polymorphisms are enigmatic
because they lack conditionality, and genes causing adaptive trait variation in
one sex may reduce Darwinian fitness in the other. One way to avoid such genetic
antagonism is to control sex-specific traits by inheritance via sex chromosomes.
Here, controlled laboratory crossings suggest that in snail-brooding cichlid fish
a single locus, two-allele polymorphism located on a sex-linked chromosome of
heterogametic males generates an extreme reproductive dimorphism. Both natural
and sexual selection are responsible for exceptionally large body size of bourgeois
males, creating a niche for a miniature male phenotype to evolve. This extreme
intrasexual dimorphism results from selection on opposite size thresholds caused
by a single ecological factor, empty snail shells used as breeding substrate.
Paternity analyses reveal that in the field parasitic dwarf males sire the majority
of offspring in direct sperm competition with large nest owners exceeding their
size more than 40 times. Apparently, use of empty snail shells as breeding substrate
and single locus sex-linked inheritance of growth are the major ecological and
genetic mechanisms responsible for the extreme intrasexual diversity observed
in Lamprologus callipterus.

text: We provide theoretical tests of a novel experimental technique to determine
mechanostability of proteins based on stretching a mechanically protected protein
by single-molecule force spectroscopy. This technique involves stretching a homogeneous
or heterogeneous chain of reference proteins (single-molecule markers) in which
one of them acts as host to the guest protein under study. The guest protein is
grafted into the host through genetic engineering. It is expected that unraveling
of the host precedes the unraveling of the guest removing ambiguities in the reading
of the force-extension patterns of the guest protein. We study examples of such
systems within a coarse-grained structure-based model. We consider systems with
various ratios of mechanostability for the host and guest molecules and compare
them to experimental results involving cohesin I as the guest molecule. For a
comparison, we also study the force-displacement patterns in proteins that are
linked in a serial fashion. We find that the mechanostability of the guest is
similar to that of the isolated or serially linked protein. We also demonstrate
that the ideal configuration of this strategy would be one in which the host is
much more mechanostable than the single-molecule markers. We finally show that
it is troublesome to use the highly stable cystine knot proteins as a host to
graft a guest in stretching studies because this would involve a cleaving procedure.

text: Unbiased high-throughput massively parallel sequencing methods have transformed
the process of discovery of novel putative driver gene mutations in cancer. In
chronic lymphocytic leukemia (CLL), these methods have yielded several unexpected
findings, including the driver genes SF3B1, NOTCH1 and POT1. Recent analysis,
utilizing down-sampling of existing datasets, has shown that the discovery process
of putative drivers is far from complete across cancer. In CLL, while driver gene
mutations affecting >10% of patients were efficiently discovered with previously
published CLL cohorts of up to 160 samples subjected to whole exome sequencing
(WES), this sample size has only 0.78 power to detect drivers affecting 5% of
patients, and only 0.12 power for drivers affecting 2% of patients. These calculations
emphasize the need to apply unbiased WES to larger patient cohorts.

text: We study translation-invariant quasi-free states for a system of fermions
with two-particle interactions. The associated energy functional is similar to
the BCS functional but also includes direct and exchange energies. We show that
for suitable short-range interactions, these latter terms only lead to a renormalization
of the chemical potential, with the usual properties of the BCS functional left
unchanged. Our analysis thus represents a rigorous justification of part of the
BCS approximation. We give bounds on the critical temperature below which the
system displays superfluidity.

text: 'Background: Bacterial Dsb enzymes are involved in the oxidative folding of
many proteins, through the formation of disulfide bonds between their cysteine
residues. The Dsb protein network has been well characterized in cells of the
model microorganism Escherichia coli. To gain insight into the functioning of
the Dsb system in epsilon-Proteobacteria, where it plays an important role in
the colonization process, we studied two homologs of the main Escherichia coli
Dsb oxidase (EcDsbA) that are present in the cells of the enteric pathogen Campylobacter
jejuni, the most frequently reported bacterial cause of human enteritis in the
world. Methods and Results: Phylogenetic analysis suggests the horizontal transfer
of the epsilon-Proteobacterial DsbAs from a common ancestor to gamma-Proteobacteria,
which then gave rise to the DsbL lineage. Phenotype and enzymatic assays suggest
that the two C. jejuni DsbAs play different roles in bacterial cells and have
divergent substrate spectra. CjDsbA1 is essential for the motility and autoagglutination
phenotypes, while CjDsbA2 has no impact on those processes. CjDsbA1 plays a critical
role in the oxidative folding that ensures the activity of alkaline phosphatase
CjPhoX, whereas CjDsbA2 is crucial for the activity of arylsulfotransferase CjAstA,
encoded within the dsbA2-dsbB-astA operon. Conclusions: Our results show that
CjDsbA1 is the primary thiol-oxidoreductase affecting life processes associated
with bacterial spread and host colonization, as well as ensuring the oxidative
folding of particular protein substrates. In contrast, CjDsbA2 activity does not
affect the same processes and so far its oxidative folding activity has been demonstrated
for one substrate, arylsulfotransferase CjAstA. The results suggest the cooperation
between CjDsbA2 and CjDsbB. In the case of the CjDsbA1, this cooperation is not
exclusive and there is probably another protein to be identified in C. jejuni
cells that acts to re-oxidize CjDsbA1. Altogether the data presented here constitute
the considerable insight to the Epsilonproteobacterial Dsb systems, which have
been poorly understood so far.'

text: Major histocompatibility complex class I (MHCI) molecules were recently identified
as novel regulators of synaptic plasticity. These molecules are expressed in various
brain areas, especially in regions undergoing activity-dependent synaptic plasticity,
but their role in the nucleus accumbens (NAc) is unknown. In this study, we investigated
the effects of genetic disruption of MHCI function, through deletion of β2-microblobulin,
which causes lack of cell surface expression of MHCI. First, we confirmed that
MHCI molecules are expressed in the NAc core in wild-type mice. Second, we performed
electrophysiological recordings with NAc core slices from wild-type and β2-microglobulin
knock-out mice lacking cell surface expression of MHCI. We found that low frequency
stimulation induced long-term depression in wild-type but not knock-out mice,
whereas high frequency stimulation induced long-term potentiation in both genotypes,
with a larger magnitude in knock-out mice. Furthermore, we demonstrated that knock-out
mice showed more persistent behavioral sensitization to cocaine, which is a NAc-related
behavior. Using this model, we analyzed the density of total AMPA receptors and
their subunits GluR1 and GluR2 in the NAc core, by SDS-digested freeze-fracture
replica labeling. After repeated cocaine exposure, the density of GluR1 was increased,
but there was no change in total AMPA receptors and GluR2 levels in wildtype mice.
In contrast, following repeated cocaine exposure, increased densities of total
AMPA receptors, GluR1 and GluR2 were observed in knock-out mice. These results
indicate that functional deficiency of MHCI enhances synaptic potentiation, induced
by electrical and pharmacological stimulation.

text: Phosphatidylinositol (PtdIns) is a structural phospholipid that can be phosphorylated
into various lipid signaling molecules, designated polyphosphoinositides (PPIs).
The reversible phosphorylation of PPIs on the 3, 4, or 5 position of inositol
is performed by a set of organelle-specific kinases and phosphatases, and the
characteristic head groups make these molecules ideal for regulating biological
processes in time and space. In yeast and mammals, PtdIns3P and PtdIns(3,5)P2
play crucial roles in trafficking toward the lytic compartments, whereas the role
in plants is not yet fully understood. Here we identified the role of a land plant-specific
subgroup of PPI phosphatases, the suppressor of actin 2 (SAC2) to SAC5, during
vacuolar trafficking and morphogenesis in Arabidopsis thaliana. SAC2-SAC5 localize
to the tonoplast along with PtdIns3P, the presumable product of their activity.
In SAC gain- and loss-of-function mutants, the levels of PtdIns monophosphates
and bisphosphates were changed, with opposite effects on the morphology of storage
and lytic vacuoles, and the trafficking toward the vacuoles was defective. Moreover,
multiple sac knockout mutants had an increased number of smaller storage and lytic
vacuoles, whereas extralarge vacuoles were observed in the overexpression lines,
correlating with various growth and developmental defects. The fragmented vacuolar
phenotype of sac mutants could be mimicked by treating wild-type seedlings with
PtdIns(3,5)P2, corroborating that this PPI is important for vacuole morphology.
Taken together, these results provide evidence that PPIs, together with their
metabolic enzymes SAC2-SAC5, are crucial for vacuolar trafficking and for vacuolar
morphology and function in plants.

text: 'Biopolymer length regulation is a complex process that involves a large number
of biological, chemical, and physical subprocesses acting simultaneously across
multiple spatial and temporal scales. An illustrative example important for genomic
stability is the length regulation of telomeres - nucleoprotein structures at
the ends of linear chromosomes consisting of tandemly repeated DNA sequences and
a specialized set of proteins. Maintenance of telomeres is often facilitated by
the enzyme telomerase but, particularly in telomerase-free systems, the maintenance
of chromosomal termini depends on alternative lengthening of telomeres (ALT) mechanisms
mediated by recombination. Various linear and circular DNA structures were identified
to participate in ALT, however, dynamics of the whole process is still poorly
understood. We propose a chemical kinetics model of ALT with kinetic rates systematically
derived from the biophysics of DNA diffusion and looping. The reaction system
is reduced to a coagulation-fragmentation system by quasi-steady-state approximation.
The detailed treatment of kinetic rates yields explicit formulas for expected
size distributions of telomeres that demonstrate the key role played by the J
factor, a quantitative measure of bending of polymers. The results are in agreement
with experimental data and point out interesting phenomena: an appearance of very
long telomeric circles if the total telomere density exceeds a critical value
(excess mass) and a nonlinear response of the telomere size distributions to the
amount of telomeric DNA in the system. The results can be of general importance
for understanding dynamics of telomeres in telomerase-independent systems as this
mode of telomere maintenance is similar to the situation in tumor cells lacking
telomerase activity. Furthermore, due to its universality, the model may also
serve as a prototype of an interaction between linear and circular DNA structures
in various settings.'

text: GNOM is one of the most characterized membrane trafficking regulators in plants,
with crucial roles in development. GNOM encodes an ARF-guanine nucleotide exchange
factor (ARF-GEF) that activates small GTPases of the ARF (ADP ribosylation factor)
class to mediate vesicle budding at endomembranes. The crucial role of GNOM in
recycling of PIN auxin transporters and other proteins to the plasma membrane
was identified in studies using the ARF-GEF inhibitor brefeldin A (BFA). GNOM,
the most prominent regulator of recycling in plants, has been proposed to act
and localize at so far elusive recycling endosomes. Here, we report the GNOM localization
in context of its cellular function in Arabidopsis thaliana. State-of-the-art
imaging, pharmacological interference, and ultrastructure analysis show that GNOM
predominantly localizes to Golgi apparatus. Super-resolution confocal live imaging
microscopy identified GNOM and its closest homolog GNOM-like 1 at distinct subdomains
on Golgi cisternae. Short-term BFA treatment stabilizes GNOM at the Golgi apparatus,
whereas prolonged exposures results in GNOM translocation to trans-Golgi network
(TGN)/early endosomes (EEs). Malformed TGN/EE in gnom mutants suggests a role
for GNOM in maintaining TGN/EE function. Our results redefine the subcellular
action of GNOM and reevaluate the identity and function of recycling endosomes
in plants.

Morphogenesis involves perpendicular (asymmetric) divisions and the spindle orientation
protein LGN, but little is known about how the apical localization of LGN is regulated.
Here, we combine conventional genetics and lentiviral-mediated in vivo RNAi to
explore the functions of the LGN-interacting proteins Par3, mInsc and Gα i3. Whereas
loss of each gene alone leads to randomized division angles, combined loss of
Gnai3 and mInsc causes a phenotype of mostly planar divisions, akin to loss of
LGN. These findings lend experimental support for the hitherto untested model
that Par3-mInsc and Gα i3 act cooperatively to polarize LGN and promote perpendicular
divisions. Finally, we uncover a developmental switch between delamination-driven
early stratification and spindle-orientation-dependent differentiation that occurs
around E15, revealing a two-step mechanism underlying epidermal maturation.

text: Fast synaptic transmission is important for rapid information processing.
To explore the maximal rate of neuronal signaling and to analyze the presynaptic
mechanisms, we focused on the input layer of the cerebellar cortex, where exceptionally
high action potential (AP) frequencies have been reported invivo. With paired
recordings between presynaptic cerebellar mossy fiber boutons and postsynaptic
granule cells, we demonstrate reliable neurotransmission upto ~1 kHz. Presynaptic
APs are ultrafast, with ~100μs half-duration. Both Kv1 and Kv3 potassium channels
mediate the fast repolarization, rapidly inactivating sodium channels ensure metabolic
efficiency, and little AP broadening occurs during bursts of up to 1.5 kHz. Presynaptic
Cav2.1 (P/Q-type) calcium channels open efficiently during ultrafast APs. Furthermore,
a subset of synaptic vesicles is tightly coupled to Ca2+ channels, and vesicles
are rapidly recruited to the release site. These data reveal mechanisms of presynaptic
AP generation and transmitter release underlying neuronal kHz signaling.

text: In this paper, we introduce a novel scene representation for the visualization
of large-scale point clouds accompanied by a set of high-resolution photographs.
Many real-world applications deal with very densely sampled point-cloud data,
which are augmented with photographs that often reveal lighting variations and
inaccuracies in registration. Consequently, the high-quality representation of
the captured data, i.e., both point clouds and photographs together, is a challenging
and time-consuming task. We propose a two-phase approach, in which the first (preprocessing)
phase generates multiple overlapping surface patches and handles the problem of
seamless texture generation locally for each patch. The second phase stitches
these patches at render-time to produce a high-quality visualization of the data.
As a result of the proposed localization of the global texturing problem, our
algorithm is more than an order of magnitude faster than equivalent mesh-based
texturing techniques. Furthermore, since our preprocessing phase requires only
a minor fraction of the whole data set at once, we provide maximum flexibility
when dealing with growing data sets.

text: The unprecedented polymorphism in the major histocompatibility complex (MHC)
genes is thought to be maintained by balancing selection from parasites. However,
do parasites also drive divergence at MHC loci between host populations, or do
the effects of balancing selection maintain similarities among populations? We
examined MHC variation in populations of the livebearing fish Poecilia mexicana
and characterized their parasite communities. Poecilia mexicana populations in
the Cueva del Azufre system are locally adapted to darkness and the presence of
toxic hydrogen sulphide, representing highly divergent ecotypes or incipient species.
Parasite communities differed significantly across populations, and populations
with higher parasite loads had higher levels of diversity at class II MHC genes.
However, despite different parasite communities, marked divergence in adaptive
traits and in neutral genetic markers, we found MHC alleles to be remarkably similar
among host populations. Our findings indicate that balancing selection from parasites
maintains immunogenetic diversity of hosts, but this process does not promote
MHC divergence in this system. On the contrary, we suggest that balancing selection
on immunogenetic loci may outweigh divergent selection causing divergence, thereby
hindering host divergence and speciation. Our findings support the hypothesis
that balancing selection maintains MHC similarities among lineages during and
after speciation (trans-species evolution).

text: In the 1960s-1980s, determination of bacterial growth rates was an important
tool in microbial genetics, biochemistry, molecular biology, and microbial physiology.
The exciting technical developments of the 1990s and the 2000s eclipsed that tool;
as a result, many investigators today lack experience with growth rate measurements.
Recently, investigators in a number of areas have started to use measurements
of bacterial growth rates for a variety of purposes. Those measurements have been
greatly facilitated by the availability of microwell plate readers that permit
the simultaneous measurements on up to 384 different cultures. Only the exponential
(logarithmic) portions of the resulting growth curves are useful for determining
growth rates, and manual determination of that portion and calculation of growth
rates can be tedious for high-throughput purposes. Here, we introduce the program
GrowthRates that uses plate reader output files to automatically determine the
exponential portion of the curve and to automatically calculate the growth rate,
the maximum culture density, and the duration of the growth lag phase. GrowthRates
is freely available for Macintosh, Windows, and Linux.We discuss the effects of
culture volume, the classical bacterial growth curve, and the differences between
determinations in rich media and minimal (mineral salts) media. This protocol
covers calibration of the plate reader, growth of culture inocula for both rich
and minimal media, and experimental setup. As a guide to reliability, we report
typical day-to-day variation in growth rates and variation within experiments
with respect to position of wells within the plates.

text: In plants, the patterning of stem cell-enriched meristems requires a graded
auxin response maximum that emerges from the concerted action of polar auxin transport,
auxin biosynthesis, auxin metabolism, and cellular auxin response machinery. However,
mechanisms underlying this auxin response maximum-mediated root stem cell maintenance
are not fully understood. Here, we present unexpected evidence that WUSCHEL-RELATED
HOMEOBOX 5 (WOX5) transcription factor modulates expression of auxin biosynthetic
genes in the quiescent center (QC) of the root and thus provides a robust mechanism
for the maintenance of auxin response maximum in the root tip. This WOX5 action
is balanced through the activity of indole-3-acetic acid 17 (IAA17) auxin response
repressor. Our combined genetic, cell biology, and computational modeling studies
revealed a previously uncharacterized feedback loop linking WOX5-mediated auxin
production to IAA17-dependent repression of auxin responses. This WOX5-IAA17 feedback
circuit further assures the maintenance of auxin response maximum in the root
tip and thereby contributes to the maintenance of distal stem cell (DSC) populations.
Our experimental studies and in silico computer simulations both demonstrate that
the WOX5-IAA17 feedback circuit is essential for the maintenance of auxin gradient
in the root tip and the auxin-mediated root DSC differentiation.

text: We prove a Strichartz inequality for a system of orthonormal functions, with
an optimal behavior of the constant in the limit of a large number of functions.
The estimate generalizes the usual Strichartz inequality, in the same fashion
as the Lieb-Thirring inequality generalizes the Sobolev inequality. As an application,
we consider the Schrödinger equation with a time-dependent potential and we show
the existence of the wave operator in Schatten spaces.

text: Epithelial cell layers need to be tightly regulated to maintain their integrity
and correct function. Cell integration into epithelial sheets is now shown to
depend on the N-WASP-regulated stabilization of cortical F-actin, which generates
distinct patterns of apical-lateral contractility at E-cadherin-based cell-cell
junctions.

text: 'Summary: Phenotypes are often environmentally dependent, which requires organisms
to track environmental change. The challenge for organisms is to construct phenotypes
using the most accurate environmental cue. Here, we use a quantitative genetic
model of adaptation by additive genetic variance, within- and transgenerational
plasticity via linear reaction norms and indirect genetic effects respectively.
We show how the relative influence on the eventual phenotype of these components
depends on the predictability of environmental change (fast or slow, sinusoidal
or stochastic) and the developmental lag τ between when the environment is perceived
and when selection acts. We then decompose expected mean fitness into three components
(variance load, adaptation and fluctuation load) to study the fitness costs of
within- and transgenerational plasticity. A strongly negative maternal effect
coefficient m minimizes the variance load, but a strongly positive m minimises
the fluctuation load. The adaptation term is maximized closer to zero, with positive
or negative m preferred under different environmental scenarios. Phenotypic plasticity
is higher when τ is shorter and when the environment changes frequently between
seasonal extremes. Expected mean population fitness is highest away from highest
observed levels of phenotypic plasticity. Within- and transgenerational plasticity
act in concert to deliver well-adapted phenotypes, which emphasizes the need to
study both simultaneously when investigating phenotypic evolution.'

text: angerhans cells (LCs) are a unique subset of dendritic cells (DCs) that express
epithelial adhesion molecules, allowing them to form contacts with epithelial
cells and reside in epidermal/epithelial tissues. The dynamic regulation of epithelial
adhesion plays a decisive role in the life cycle of LCs. It controls whether LCs
remain immature and sessile within the epidermis or mature and egress to initiate
immune responses. So far, the molecular machinery regulating epithelial adhesion
molecules during LC maturation remains elusive. Here, we generated pure populations
of immature human LCs in vitro to systematically probe for gene-expression changes
during LC maturation. LCs down-regulate a set of epithelial genes including E-cadherin,
while they upregulate the mesenchymal marker N-cadherin known to facilitate cell
migration. In addition, N-cadherin is constitutively expressed by monocyte-derived
DCs known to exhibit characteristics of both inflammatory-type and interstitial/dermal
DCs. Moreover, the transcription factors ZEB1 and ZEB2 (ZEB is zinc-finger E-box-binding
homeobox) are upregulated in migratory LCs. ZEB1 and ZEB2 have been shown to induce
epithelial-to-mesenchymal transition (EMT) and invasive behavior in cancer cells
undergoing metastasis. Our results provide the first hint that the molecular EMT
machinery might facilitate LC mobilization. Moreover, our study suggests that
N-cadherin plays a role during DC migration.

text: 'Most cryptographic security proofs require showing that two systems are indistinguishable.
A central tool in such proofs is that of a game, where winning the game means
provoking a certain condition, and it is shown that the two systems considered
cannot be distinguished unless this condition is provoked. Upper bounding the
probability of winning such a game, i.e., provoking this condition, for an arbitrary
strategy is usually hard, except in the special case where the best strategy for
winning such a game is known to be non-adaptive. A sufficient criterion for ensuring
the optimality of non-adaptive strategies is that of conditional equivalence to
a system, a notion introduced in [1]. In this paper, we show that this criterion
is not necessary to ensure the optimality of non-adaptive strategies by giving
two results of independent interest: 1) the optimality of non-adaptive strategies
is not preserved under parallel composition; 2) in contrast, conditional equivalence
is preserved under parallel composition.'

text: In large populations, multiple beneficial mutations may be simultaneously
spreading. In asexual populations, these mutations must either arise on the same
background or compete against each other. In sexual populations, recombination
can bring together beneficial alleles from different backgrounds, but tightly
linked alleles may still greatly interfere with each other. We show for well-mixed
populations that when this interference is strong, the genome can be seen as consisting
of many effectively asexual stretches linked together. The rate at which beneficial
alleles fix is thus roughly proportional to the rate of recombination and depends
only logarithmically on the mutation supply and the strength of selection. Our
scaling arguments also allow us to predict, with reasonable accuracy, the fitness
distribution of fixed mutations when the mutational effect sizes are broad. We
focus on the regime in which crossovers occur more frequently than beneficial
mutations, as is likely to be the case for many natural populations.

text: The topological Tverberg theorem has been generalized in several directions
by setting extra restrictions on the Tverberg partitions. Restricted Tverberg
partitions, defined by the idea that certain points cannot be in the same part,
are encoded with graphs. When two points are adjacent in the graph, they are not
in the same part. If the restrictions are too harsh, then the topological Tverberg
theorem fails. The colored Tverberg theorem corresponds to graphs constructed
as disjoint unions of small complete graphs. Hell studied the case of paths and
cycles. In graph theory these partitions are usually viewed as graph colorings.
As explored by Aharoni, Haxell, Meshulam and others there are fundamental connections
between several notions of graph colorings and topological combinatorics. For
ordinary graph colorings it is enough to require that the number of colors q satisfy
q>Δ, where Δ is the maximal degree of the graph. It was proven by the first
author using equivariant topology that if q>Δ 2 then the topological Tverberg
theorem still works. It is conjectured that q>KΔ is also enough for some constant
K, and in this paper we prove a fixed-parameter version of that conjecture. The
required topological connectivity results are proven with shellability, which
also strengthens some previous partial results where the topological connectivity
was proven with the nerve lemma.

text: Hereditary spastic paraplegias (HSPs) are neurodegenerative motor neuron diseases
characterized by progressive age-dependent loss of corticospinal motor tract function.
Although the genetic basis is partly understood, only a fraction of cases can
receive a genetic diagnosis, and a global view of HSP is lacking. By using whole-exome
sequencing in combination with network analysis, we identified 18 previously unknown
putative HSP genes and validated nearly all of these genes functionally or genetically.
The pathways highlighted by these mutations link HSP to cellular transport, nucleotide
metabolism, and synapse and axon development. Network analysis revealed a host
of further candidate genes, of which three were mutated in our cohort. Our analysis
links HSP to other neurodegenerative disorders and can facilitate gene discovery
and mechanistic understanding of disease.

text: Auxin-binding protein 1 (ABP1) was discovered nearly 40 years ago and was
shown to be essential for plant development and morphogenesis, but its mode of
action remains unclear. Here, we report that the plasma membrane-localized transmembrane
kinase (TMK) receptor-like kinases interact with ABP1 and transduce auxin signal
to activate plasma membrane-associated ROPs [Rho-like guanosine triphosphatases
(GTPase) from plants], leading to changes in the cytoskeleton and the shape of
leaf pavement cells in Arabidopsis. The interaction between ABP1 and TMK at the
cell surface is induced by auxin and requires ABP1 sensing of auxin. These findings
show that TMK proteins and ABP1 form a cell surface auxin perception complex that
activates ROP signaling pathways, regulating nontranscriptional cytoplasmic responses
and associated fundamental processes.

text: Cerebellar motor learning is suggested to be caused by long-term plasticity
of excitatory parallel fiber-Purkinje cell (PF-PC) synapses associated with changes
in the number of synaptic AMPA-type glutamate receptors (AMPARs). However, whether
the AMPARs decrease or increase in individual PF-PC synapses occurs in physiological
motor learning and accounts for memory that lasts over days remains elusive. We
combined quantitative SDS-digested freeze-fracture replica labeling for AMPAR
and physical dissector electron microscopy with a simple model of cerebellar motor
learning, adaptation of horizontal optokinetic response (HOKR) in mouse. After
1-h training of HOKR, short-term adaptation (STA) was accompanied with transient
decrease in AMPARs by 28% in target PF-PC synapses. STA was well correlated with
AMPAR decrease in individual animals and both STA and AMPAR decrease recovered
to basal levels within 24 h. Surprisingly, long-termadaptation (LTA) after five
consecutive daily trainings of 1-h HOKR did not alter the number of AMPARs in
PF-PC synapses but caused gradual and persistent synapse elimination by 45%, with
corresponding PC spine loss by the fifth training day. Furthermore, recovery of
LTA after 2 wk was well correlated with increase of PF-PC synapses to the control
level. Our findings indicate that the AMPARs decrease in PF-PC synapses and the
elimination of these synapses are in vivo engrams in short- and long-term motor
learning, respectively, showing a unique type of synaptic plasticity that may
contribute to memory consolidation.

text: ROPs (Rho of plants) belong to a large family of plant-specific Rho-like small
GTPases that function as essential molecular switches to control diverse cellular
processes including cytoskeleton organization, cell polarization, cytokinesis,
cell differentiation and vesicle trafficking. Although the machineries of vesicle
trafficking and cell polarity in plants have been individually well addressed,
how ROPs co-ordinate those processes is still largely unclear. Recent progress
has been made towards an understanding of the coordination of ROP signalling and
trafficking of PIN (PINFORMED) transporters for the plant hormone auxin in both
root and leaf pavement cells. PIN transporters constantly shuttle between the
endosomal compartments and the polar plasma membrane domains, therefore the modulation
of PIN-dependent auxin transport between cells is a main developmental output
of ROP-regulated vesicle trafficking. The present review focuses on these cellular
mechanisms, especially the integration of ROP-based vesicle trafficking and plant
cell polarity.

text: Long-lasting memories are formed when the stimulus is temporally distributed
(spacing effect). However, the synaptic mechanisms underlying this robust phenomenon
and the precise time course of the synaptic modifications that occur during learning
remain unclear. Here we examined the adaptation of horizontal optokinetic response
in mice that underwent 1 h of massed and spaced training at varying intervals.
Despite similar acquisition by all training protocols, 1 h of spacing produced
the highest memory retention at 24 h, which lasted for 1 mo. The distinct kinetics
of memory are strongly correlated with the reduction of floccular parallel fiber-Purkinje
cell synapses but not with AMPA receptor (AMPAR) number and synapse size. After
the spaced training, we observed 25%, 23%, and 12% reduction in AMPAR density,
synapse size, and synapse number, respectively. Four hours after the spaced training,
half of the synapses and Purkinje cell spines had been eliminated, whereas AMPAR
density and synapse size were recovered in remaining synapses. Surprisingly, massed
training also produced long-term memory and halving of synapses; however, this
occurred slowly over days, and the memory lasted for only 1 wk. This distinct
kinetics of structural plasticity may serve as a basis for unique temporal profiles
in the formation and decay of memory with or without intervals.

text: As the nuclear charge Z is continuously decreased an N-electron atom undergoes
a binding-unbinding transition. We investigate whether the electrons remain bound
and whether the radius of the system stays finite as the critical value Zc is
approached. Existence of a ground state at Zc is shown under the condition Zc
< N-K, where K is the maximal number of electrons that can be removed at Zc
without changing the energy.

text: Targeting membrane proteins for degradation requires the sequential action
of ESCRT sub-complexes ESCRT-0 to ESCRT-III. Although this machinery is generally
conserved among kingdoms, plants lack the essential ESCRT-0 components. A new
report closes this gap by identifying a novel protein family that substitutes
for ESCRT-0 function in plants.

text: In the past decade carbon nanotubes (CNTs) have been widely studied as a potential
drug-delivery system, especially with functionality for cellular targeting. Yet,
little is known about the actual process of docking to cell receptors and transport
dynamics after internalization. Here we performed single-particle studies of folic
acid (FA) mediated CNT binding to human carcinoma cells and their transport inside
the cytosol. In particular, we employed molecular recognition force spectroscopy,
an atomic force microscopy based method, to visualize and quantify docking of
FA functionalized CNTs to FA binding receptors in terms of binding probability
and binding force. We then traced individual fluorescently labeled, FA functionalized
CNTs after specific uptake, and created a dynamic 'roadmap' that clearly showed
trajectories of directed diffusion and areas of nanotube confinement in the cytosol.
Our results demonstrate the potential of a single-molecule approach for investigation
of drug-delivery vehicles and their targeting capacity.

text: We derive the equations for a thin, axisymmetric elastic shell subjected to
an internal active stress giving rise to active tension and moments within the
shell. We discuss the stability of a cylindrical elastic shell and its response
to a localized change in internal active stress. This description is relevant
to describe the cellular actomyosin cortex, a thin shell at the cell surface behaving
elastically at a short timescale and subjected to active internal forces arising
from myosin molecular motor activity. We show that the recent observations of
cell deformation following detachment of adherent cells (Maître J-L et al 2012
Science 338 253-6) are well accounted for by this mechanical description. The
actin cortex elastic and bending moduli can be obtained from a quantitative analysis
of cell shapes observed in these experiments. Our approach thus provides a non-invasive,
imaging-based method for the extraction of cellular physical parameters.

text: Cell polarity manifested by asymmetric distribution of cargoes, such as receptors
and transporters, within the plasma membrane (PM) is crucial for essential functions
in multicellular organisms. In plants, cell polarity (re)establishment is intimately
linked to patterning processes. Despite the importance of cell polarity, its underlying
mechanisms are still largely unknown, including the definition and distinctiveness
of the polar domains within the PM. Here, we show in Arabidopsis thaliana that
the signaling membrane components, the phosphoinositides phosphatidylinositol
4-phosphate (PtdIns4P) and phosphatidylinositol 4, 5-bisphosphate [PtdIns(4, 5)P2]
as well as PtdIns4P 5-kinases mediating their interconversion, are specifically
enriched at apical and basal polar plasma membrane domains. The PtdIns4P 5-kinases
PIP5K1 and PIP5K2 are redundantly required for polar localization of specifically
apical and basal cargoes, such as PIN-FORMED transporters for the plant hormone
auxin. As a consequence of the polarity defects, instructive auxin gradients as
well as embryonic and postembryonic patterning are severely compromised. Furthermore,
auxin itself regulates PIP5K transcription and PtdIns4P and PtdIns(4, 5)P2 levels,
in particular their association with polar PM domains. Our results provide insight
into the polar domain-delineating mechanisms in plant cells that depend on apical
and basal distribution of membrane lipids and are essential for embryonic and
postembryonic patterning.

text: Germination of Arabidopsis seeds in darkness induces apical hook development,
based on a tightly regulated differential growth coordinated by a multiple hormone
cross-talk. Here, we endeavoured to clarify the function of brassinosteroids (BRs)
and cross-talk with ethylene in hook development. An automated infrared imaging
system was developed to study the kinetics of hook development in etiolated Arabidopsis
seedlings. To ascertain the photomorphogenic control of hook opening, the system
was equipped with an automatic light dimmer. We demonstrate that ethylene and
BRs are indispensable for hook formation and maintenance. Ethylene regulation
of hook formation functions partly through BRs, with BR feedback inhibition of
ethylene action. Conversely, BR-mediated extension of hook maintenance functions
partly through ethylene. Furthermore, we revealed that a short light pulse is
sufficient to induce rapid hook opening. Our dynamic infrared imaging system allows
high-resolution, kinetic imaging of up to 112 seedlings in a single experimental
run. At this high throughput, it is ideally suited to rapidly gain insight in
pathway networks. We demonstrate that BRs and ethylene cooperatively regulate
apical hook development in a phase-dependent manner. Furthermore, we show that
light is a predominant regulator of hook opening, inhibiting ethylene- and BR-mediated
postponement of hook opening.

text: Constrained pseudorandom functions have recently been introduced independently
by Boneh and Waters (Asiacrypt’13), Kiayias et al. (CCS’13), and Boyle et al.
(PKC’14). In a standard pseudorandom function (PRF) a key k is used to evaluate
the PRF on all inputs in the domain. Constrained PRFs additionally offer the functionality
to delegate “constrained” keys kS which allow to evaluate the PRF only on a subset
S of the domain. The three above-mentioned papers all show that the classical
GGM construction (J.ACM’86) of a PRF from a pseudorandom generator (PRG) directly
yields a constrained PRF where one can compute constrained keys to evaluate the
PRF on all inputs with a given prefix. This constrained PRF has already found
many interesting applications. Unfortunately, the existing security proofs only
show selective security (by a reduction to the security of the underlying PRG).
To achieve full security, one has to use complexity leveraging, which loses an
exponential factor 2N in security, where N is the input length. The first contribution
of this paper is a new reduction that only loses a quasipolynomial factor qlog
N, where q is the number of adversarial queries. For this we develop a new proof
technique which constructs a distinguisher by interleaving simple guessing steps
and hybrid arguments a small number of times. This approach might be of interest
also in other contexts where currently the only technique to achieve full security
is complexity leveraging. Our second contribution is concerned with another constrained
PRF, due to Boneh and Waters, which allows for constrained keys for the more general
class of bit-fixing functions. Their security proof also suffers from a 2N loss,
which we show is inherent. We construct a meta-reduction which shows that any
“simple” reduction of full security from a noninteractive hardness assumption
must incur an exponential security loss.

text: We consider cross products of finite graphs with a class of trees that have
arbitrarily but finitely long line segments, such as the Fibonacci tree. Such
cross products are called tree-strips. We prove that for small disorder random
Schrödinger operators on such tree-strips have purely absolutely continuous spectrum
in a certain set.

text: Stomata are two-celled valves that control epidermal pores whose spacing optimizes
shoot-atmosphere gas exchange. They develop from protodermal cells after unequal
divisions followed by an equal division and differentiation. The concentration
of the hormone auxin, a master plant developmental regulator, is tightly controlled
in time and space, but its role, if any, in stomatal formation is obscure. Here
dynamic changes of auxin activity during stomatal development are monitored using
auxin input (DII-VENUS) and output (DR5:VENUS) markers by time-lapse imaging.
A decrease in auxin levels in the smaller daughter cell after unequal division
presages the acquisition of a guard mother cell fate whose equal division produces
the two guard cells. Thus, stomatal patterning requires auxin pathway control
of stem cell compartment size, as well as auxin depletion that triggers a developmental
switch from unequal to equal division.

text: In infectious disease epidemiology the basic reproductive ratio, R0, is defined
as the average number of new infections caused by a single infected individual
in a fully susceptible population. Many models describing competition for hosts
between non-interacting pathogen strains in an infinite population lead to the
conclusion that selection favors invasion of new strains if and only if they have
higher R0 values than the resident. Here we demonstrate that this picture fails
in finite populations. Using a simple stochastic SIS model, we show that in general
there is no analogous optimization principle. We find that successive invasions
may in some cases lead to strains that infect a smaller fraction of the host population,
and that mutually invasible pathogen strains exist. In the limit of weak selection
we demonstrate that an optimization principle does exist, although it differs
from R0 maximization. For strains with very large R0, we derive an expression
for this local fitness function and use it to establish a lower bound for the
error caused by neglecting stochastic effects. Furthermore, we apply this weak
selection limit to investigate the selection dynamics in the presence of a trade-off
between the virulence and the transmission rate of a pathogen.

text: 'We consider Ising models in d = 2 and d = 3 dimensions with nearest neighbor
ferromagnetic and long-range antiferromagnetic interactions, the latter decaying
as (distance)-p, p > 2d, at large distances. If the strength J of the ferromagnetic
interaction is larger than a critical value J c, then the ground state is homogeneous.
It has been conjectured that when J is smaller than but close to J c, the ground
state is periodic and striped, with stripes of constant width h = h(J), and h
→ ∞ as J → Jc -. (In d = 3 stripes mean slabs, not columns.) Here we rigorously
prove that, if we normalize the energy in such a way that the energy of the homogeneous
state is zero, then the ratio e 0(J)/e S(J) tends to 1 as J → Jc -, with e S(J)
being the energy per site of the optimal periodic striped/slabbed state and e
0(J) the actual ground state energy per site of the system. Our proof comes with
explicit bounds on the difference e 0(J)-e S(J) at small but positive J c-J, and
also shows that in this parameter range the ground state is striped/slabbed in
a certain sense: namely, if one looks at a randomly chosen window, of suitable
size ℓ (very large compared to the optimal stripe size h(J)), one finds a striped/slabbed
state with high probability.'

text: 'The social intelligence hypothesis states that the need to cope with complexities
of social life has driven the evolution of advanced cognitive abilities. It is
usually invoked in the context of challenges arising from complex intragroup structures,
hierarchies, and alliances. However, a fundamental aspect of group living remains
largely unexplored as a driving force in cognitive evolution: the competition
between individuals searching for resources (producers) and conspecifics that
parasitize their findings (scroungers). In populations of social foragers, abilities
that enable scroungers to steal by outsmarting producers, and those allowing producers
to prevent theft by outsmarting scroungers, are likely to be beneficial and may
fuel a cognitive arms race. Using analytical theory and agent-based simulations,
we present a general model for such a race that is driven by the producer-scrounger
game and show that the race''s plausibility is dramatically affected by the nature
of the evolving abilities. If scrounging and scrounging avoidance rely on separate,
strategy-specific cognitive abilities, arms races are short-lived and have a limited
effect on cognition. However, general cognitive abilities that facilitate both
scrounging and scrounging avoidance undergo stable, long-lasting arms races. Thus,
ubiquitous foraging interactions may lead to the evolution of general cognitive
abilities in social animals, without the requirement of complex intragroup structures.'

text: The plant hormones auxin and cytokinin mutually coordinate their activities
to control various aspects of development [1-9], and their crosstalk occurs at
multiple levels [10, 11]. Cytokinin-mediated modulation of auxin transport provides
an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate
that cytokinin does not merely control the overall auxin flow capacity, but might
also act as a polarizing cue and control the auxin stream directionality during
plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter
depletion at specific polar domains, thus rearranging the cellular PIN polarities
and directly regulating the auxin flow direction. This selective cytokinin sensitivity
correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking
mutations, as well as enhanced phosphorylation in plants with modulated activities
of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results
reveal conceptually novel, cytokinin-driven polarization mechanism that operates
in developmental processes involving rapid auxin stream redirection, such as lateral
root organogenesis, in which a gradual PIN polarity switch defines the growth
axis of the newly formed organ.

text: The existence of complex (multiple-step) genetic adaptations that are "irreducible"
(i.e., all partial combinations are less fit than the original genotype) is one
of the longest standing problems in evolutionary biology. In standard genetics
parlance, these adaptations require the crossing of a wide adaptive valley of
deleterious intermediate stages. Here, we demonstrate, using a simple model, that
evolution can cross wide valleys to produce "irreducibly complex" adaptations
by making use of previously cryptic mutations. When revealed by an evolutionary
capacitor, previously cryptic mutants have higher initial frequencies than do
new mutations, bringing them closer to a valley-crossing saddle in allele frequency
space. Moreover, simple combinatorics implies an enormous number of candidate
combinations exist within available cryptic genetic variation. We model the dynamics
of crossing of a wide adaptive valley after a capacitance event using both numerical
simulations and analytical approximations. Although individual valley crossing
events become less likely as valleys widen, by taking the combinatorics of genotype
space into account, we see that revealing cryptic variation can cause the frequent
evolution of complex adaptations.

text: (Figure Presented) Data acquisition, numerical inaccuracies, and sampling
often introduce noise in measurements and simulations. Removing this noise is
often necessary for efficient analysis and visualization of this data, yet many
denoising techniques change the minima and maxima of a scalar field. For example,
the extrema can appear or disappear, spatially move, and change their value. This
can lead to wrong interpretations of the data, e.g., when the maximum temperature
over an area is falsely reported being a few degrees cooler because the denoising
method is unaware of these features. Recently, a topological denoising technique
based on a global energy optimization was proposed, which allows the topology-controlled
denoising of 2D scalar fields. While this method preserves the minima and maxima,
it is constrained by the size of the data. We extend this work to large 2D data
and medium-sized 3D data by introducing a novel domain decomposition approach.
It allows processing small patches of the domain independently while still avoiding
the introduction of new critical points. Furthermore, we propose an iterative
refinement of the solution, which decreases the optimization energy compared to
the previous approach and therefore gives smoother results that are closer to
the input. We illustrate our technique on synthetic and real-world 2D and 3D data
sets that highlight potential applications.

text: The development of the vertebrate brain requires an exquisite balance between
proliferation and differentiation of neural progenitors. Notch signaling plays
a pivotal role in regulating this balance, yet the interaction between signaling
and receiving cells remains poorly understood. We have found that numerous nascent
neurons and/or intermediate neurogenic progenitors expressing the ligand of Notch
retain apical endfeet transiently at the ventricular lumen that form adherens
junctions (AJs) with the endfeet of progenitors. Forced detachment of the apical
endfeet of those differentiating cells by disrupting AJs resulted in precocious
neurogenesis that was preceded by the downregulation of Notch signaling. Both
Notch1 and its ligand Dll1 are distributed around AJs in the apical endfeet, and
these proteins physically interact with ZO-1, a constituent of the AJ. Furthermore,
live imaging of a fluorescently tagged Notch1 demonstrated its trafficking from
the apical endfoot to the nucleus upon cleavage. Our results identified the apical
endfoot as the central site of active Notch signaling to securely prohibit inappropriate
differentiation of neural progenitors.

text: A wealth of experimental evidence suggests that working memory circuits preferentially
represent information that is behaviorally relevant. Still, we are missing a mechanistic
account of how these representations come about. Here we provide a simple explanation
for a range of experimental findings, in light of prefrontal circuits adapting
to task constraints by reward-dependent learning. In particular, we model a neural
network shaped by reward-modulated spike-timing dependent plasticity (r-STDP)
and homeostatic plasticity (intrinsic excitability and synaptic scaling). We show
that the experimentally-observed neural representations naturally emerge in an
initially unstructured circuit as it learns to solve several working memory tasks.
These results point to a critical, and previously unappreciated, role for reward-dependent
learning in shaping prefrontal cortex activity.

text: We prove the edge universality of the beta ensembles for any β ≥ 1, provided
that the limiting spectrum is supported on a single interval, and the external
potential is C4 and regular. We also prove that the edge universality holds for
generalized Wigner matrices for all symmetry classes. Moreover, our results allow
us to extend bulk universality for beta ensembles from analytic potentials to
potentials in class C4.

text: Variation in mitochondrial DNA is often assumed to be neutral and is used
to construct the genealogical relationships among populations and species. However,
if extant variation is the result of episodes of positive selection, these genealogies
may be incorrect, although this information itself may provide biologically and
evolutionary meaningful information. In fact, positive Darwinian selection has
been detected in the mitochondrial-encoded subunits that comprise complex I from
diverse taxa with seemingly dissimilar bioenergetic life histories, but the functional
implications of the selected sites are unknown. Complex I produces roughly 40%
of the proton flux that is used to synthesize ATP from ADP, and a functional model
based on the high-resolution structure of complex I described a unique biomechanical
apparatus for proton translocation. We reported positive selection at sites in
this apparatus during the evolution of Pacific salmon, and it appeared this was
also the case in published reports from other taxa, but a comparison among studies
was difficult because different statistical tests were used to detect selection
and oftentimes, specific sites were not reported. Here we review the literature
of positive selection in mitochondrial genomes, the statistical tests used to
detect selection, and the structural and functional models that are currently
available to study the physiological implications of selection. We then search
for signatures of positive selection among the coding mitochondrial genomes of
237 species with a common set of tests and verify that the ND5 subunit of complex
I is a repeated target of positive Darwinian selection in diverse taxa. We propose
a novel hypothesis to explain the results based on their bioenergetic life histories
and provide a guide for laboratory and field studies to test this hypothesis.

text: Non-proton pumping type II NADH dehydrogenase (NDH-2) plays a central role
in the respiratory metabolism of bacteria, and in the mitochondria of fungi, plants
and protists. The lack of NDH-2 in mammalian mitochondria and its essentiality
in important bacterial pathogens suggests these enzymes may represent a potential
new drug target to combat microbial pathogens. Here, we report the first crystal
structure of a bacterial NDH-2 enzyme at 2.5Å resolution from Caldalkalibacillus
thermarum. The NDH-2 structure reveals a homodimeric organization that has a unique
dimer interface. NDH-2 is localized to the cytoplasmic membrane by two separated
C-terminal membrane-anchoring regions that are essential for membrane localization
and FAD binding, but not NDH-2 dimerization. Comparison of bacterial NDH-2 with
the yeast NADH dehydrogenase (Ndi1) structure revealed non-overlapping binding
sites for quinone and NADH in the bacterial enzyme. The bacterial NDH-2 structure
establishes a framework for the structure-based design of small-molecule inhibitors.

text: NADH-ubiquinone oxidoreductase (complex I) is the first and largest enzyme
in the respiratory chain of mitochondria and many bacteria. It couples the transfer
of two electrons between NADH and ubiquinone to the translocation of four protons
across the membrane. Complex I is an L-shaped assembly formed by the hydrophilic
(peripheral) arm, containing all the redox centres performing electron transfer
and the membrane arm, containing proton-translocating machinery. Mitochondrial
complex I consists of 44 subunits of about 1 MDa in total, whilst the prokaryotic
enzyme is simpler and generally consists of 14 conserved “core” subunits. Recently
we have determined the first atomic structure of the entire complex I, using the
enzyme from Thermus thermophilus (536 kDa, 16 subunits, 9 Fe-S clusters, 64 TM
helices). Structure suggests a unique coupling mechanism, with redox energy of
electron transfer driving proton translocation via long-range (up to ~200 Å) conformational
changes. It resembles a steam engine, with coupling elements (akin to coupling
rods) linking parts of this molecular machine.

text: During animal cell division, the cleavage furrow is positioned by microtubules
that signal to the actin cortex at the cell midplane. We developed a cell-free
system to recapitulate cytokinesis signaling using cytoplasmic extract from Xenopus
eggs. Microtubules grew out as asters from artificial centrosomes and met to organize
antiparallel overlap zones. These zones blocked the interpenetration of neighboring
asters and recruited cytokinesis midzone proteins, including the chromosomal passenger
complex (CPC) and centralspindlin. The CPC was transported to overlap zones, which
required two motor proteins, Kif4A and a Kif20A paralog. Using supported lipid
bilayers to mimic the plasma membrane, we observed the recruitment of cleavage
furrow markers, including an active RhoA reporter, at microtubule overlaps. This
system opens further approaches to understanding the biophysics of cytokinesis
signaling.
