text: Our work concerns the combination of an Eulerian liquid simulation with a
high-resolution surface tracker (e.g. the level set method or a Lagrangian triangle
mesh). The naive application of a high-resolution surface tracker to a low-resolution
velocity field can produce many visually disturbing physical and topological artifacts
that limit their use in practice. We address these problems by defining an error
function which compares the current state of the surface tracker to the set of
physically valid surface states. By reducing this error with a gradient descent
technique, we introduce a novel physics-based surface fairing method. Similarly,
by treating this error function as a potential energy, we derive a new surface
correction force that mimics the vortex sheet equations. We demonstrate our results
with both level set and mesh-based surface trackers.

text: Cadherins are transmembrane proteins that mediate cell–cell adhesion in animals.
By regulating contact formation and stability, cadherins play a crucial role in
tissue morphogenesis and homeostasis. Here, we review the three major unctions
of cadherins in cell–cell contact formation and stability. Two of those functions
lead to a decrease in interfacial ension at the forming cell–cell contact, thereby
promoting contact expansion — first, by providing adhesion tension that lowers
interfacial tension at the cell–cell contact, and second, by signaling to the
actomyosin cytoskeleton in order to reduce cortex tension and thus interfacial
tension at the contact. The third function of cadherins in cell–cell contact formation
is to stabilize the contact by resisting mechanical forces that pull on the contact.

text: Background:Auxin binding protein 1 (ABP1) is a putative auxin receptor and
its function is indispensable for plant growth and development. ABP1 has been
shown to be involved in auxin-dependent regulation of cell division and expansion,
in plasma-membrane-related processes such as changes in transmembrane potential,
and in the regulation of clathrin-dependent endocytosis. However, the ABP1-regulated
downstream pathway remains elusive.Methodology/Principal Findings:Using auxin
transport assays and quantitative analysis of cellular morphology we show that
ABP1 regulates auxin efflux from tobacco BY-2 cells. The overexpression of ABP1can
counterbalance increased auxin efflux and auxin starvation phenotypes caused by
the overexpression of PIN auxin efflux carrier. Relevant mechanism involves the
ABP1-controlled vesicle trafficking processes, including positive regulation of
endocytosis of PIN auxin efflux carriers, as indicated by fluorescence recovery
after photobleaching (FRAP) and pharmacological manipulations.Conclusions/Significance:The
findings indicate the involvement of ABP1 in control of rate of auxin transport
across plasma membrane emphasizing the role of ABP1 in regulation of PIN activity
at the plasma membrane, and highlighting the relevance of ABP1 for the formation
of developmentally important, PIN-dependent auxin gradients.

text: The impact of disulfide bonds on protein stability goes beyond simple equilibrium
thermodynamics effects associated with the conformational entropy of the unfolded
state. Indeed, disulfide crosslinks may play a role in the prevention of dysfunctional
association and strongly affect the rates of irreversible enzyme inactivation,
highly relevant in biotechnological applications. While these kinetic-stability
effects remain poorly understood, by analogy with proposed mechanisms for processes
of protein aggregation and fibrillogenesis, we propose that they may be determined
by the properties of sparsely-populated, partially-unfolded intermediates. Here
we report the successful design, on the basis of high temperature molecular-dynamics
simulations, of six thermodynamically and kinetically stabilized variants of phytase
from Citrobacter braakii (a biotechnologically important enzyme) with one, two
or three engineered disulfides. Activity measurements and 3D crystal structure
determination demonstrate that the engineered crosslinks do not cause dramatic
alterations in the native structure. The inactivation kinetics for all the variants
displays a strongly non-Arrhenius temperature dependence, with the time-scale
for the irreversible denaturation process reaching a minimum at a given temperature
within the range of the denaturation transition. We show this striking feature
to be a signature of a key role played by a partially unfolded, intermediate state/ensemble.
Energetic and mutational analyses confirm that the intermediate is highly unfolded
(akin to a proposed critical intermediate in the misfolding of the prion protein),
a result that explains the observed kinetic stabilization. Our results provide
a rationale for the kinetic-stability consequences of disulfide-crosslink engineering
and an experimental methodology to arrive at energetic/structural descriptions
of the sparsely populated and elusive intermediates that play key roles in irreversible
protein denaturation.

text: Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone
auxin are required for tissue-specific directional auxin transport and cellular
auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important
roles in developmental processes such as embryogenesis, organogenesis, vascular
tissue differentiation, root meristem patterning and tropic growth. Here we analyzed
roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible
and is expressed during multiple auxin-regulated developmental processes. Loss
of pin6 function interfered with primary root growth and lateral root development.
Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis
in other growth processes such as shoot apical dominance, lateral root primordia
development, adventitious root formation, root hair outgrowth and root waving.
These changes in auxin-regulated growth correlated with a reduction in total auxin
transport as well as with an altered activity of DR5-GUS auxin response reporter.
Overall, the data indicate that PIN6 regulates auxin homeostasis during plant
development.

text: 'When a mutation with selective advantage s spreads through a panmictic population,
it may cause two lineages at a linked locus to coalesce; the probability of coalescence
is exp(−2rT), where T∼log(2Ns)/s is the time to fixation, N is the number of haploid
individuals, and r is the recombination rate. Population structure delays fixation,
and so weakens the effect of a selective sweep. However, favourable alleles spread
through a spatially continuous population behind a narrow wavefront; ancestral
lineages are confined at the tip of this front, and so coalesce rapidly. In extremely
dense populations, coalescence is dominated by rare fluctuations ahead of the
front. However, we show that for moderate densities, a simple quasi-deterministic
approximation applies: the rate of coalescence within the front is λ∼2g(η)/(ρℓ),
where ρ is the population density and is the characteristic scale of the wavefront;
g(η) depends only on the strength of random drift, . The net effect of a sweep
on coalescence also depends crucially on whether two lineages are ever both within
the wavefront at the same time: even in the extreme case when coalescence within
the front is instantaneous, the net rate of coalescence may be lower than in a
single panmictic population. Sweeps can also have a substantial impact on the
rate of gene flow. A single lineage will jump to a new location when it is hit
by a sweep, with mean square displacement ; this can be substantial if the species’
range, L, is large, even if the species-wide rate of sweeps per map length, Λ/R,
is small. This effect is half as strong in two dimensions. In contrast, the rate
of coalescence between lineages, at random locations in space and on the genetic
map, is proportional to (c/L)(Λ/R), where c is the wavespeed: thus, on average,
one-dimensional structure is likely to reduce coalescence due to sweeps, relative
to panmixis. In two dimensions, genes must move along the front before they can
coalesce; this process is rapid, being dominated by rare fluctuations. This leads
to a dramatically higher rate of coalescence within the wavefront than if lineages
simply diffused along the front. Nevertheless, the net rate of coalescence due
to a sweep through a two-dimensional population is likely to be lower than it
would be with panmixis.'

text: Despite the pivotal functions of the NMDA receptor (NMDAR) for neural circuit
development and synaptic plasticity, the molecular mechanisms underlying the dynamics
of NMDAR trafficking are poorly understood. The cell adhesion molecule neuroligin-1
(NL1) modifies NMDAR-dependent synaptic transmission and synaptic plasticity,
but it is unclear whether NL1 controls synaptic accumulation or function of the
receptors. Here, we provide evidence that NL1 regulates the abundance of NMDARs
at postsynaptic sites. This function relies on extracellular, NL1 isoform-specific
sequences that facilitate biochemical interactions between NL1 and the NMDAR GluN1
subunit. Our work uncovers NL1 isoform-specific cisinteractions with ionotropic
glutamate receptors as a key mechanism for controlling synaptic properties.

that do not always satisfy the Hasse principle. Restricting attention to a special
class of Châtelet surfaces, we investigate the frequency that such counter-examples

text: 'We study the problem of object recognition for categories for which we have
no training examples, a task also called zero-data or zero-shot learning. This
situation has hardly been studied in computer vision research, even though it
occurs frequently: the world contains tens of thousands of different object classes
and for only few of them image collections have been formed and suitably annotated.
To tackle the problem we introduce attribute-based classification: objects are
identified based on a high-level description that is phrased in terms of semantic
attributes, such as the object''s color or shape. Because the identification of
each such property transcends the specific learning task at hand, the attribute
classifiers can be pre-learned independently, e.g. from existing image datasets
unrelated to the current task. Afterwards, new classes can be detected based on
their attribute representation, without the need for a new training phase. In
this paper we also introduce a new dataset, Animals with Attributes, of over 30,000
images of 50 animal classes, annotated with 85 semantic attributes. Extensive
experiments on this and two more datasets show that attribute-based classification
indeed is able to categorize images without access to any training images of the
target classes.'

text: 'Traditional formal methods are based on a Boolean satisfaction notion: a
reactive system satisfies, or not, a given specification. We generalize formal
methods to also address the quality of systems. As an adequate specification formalism
we introduce the linear temporal logic LTL[F]. The satisfaction value of an LTL[F]
formula is a number between 0 and 1, describing the quality of the satisfaction.
The logic generalizes traditional LTL by augmenting it with a (parameterized)
set F of arbitrary functions over the interval [0,1]. For example, F may contain
the maximum or minimum between the satisfaction values of subformulas, their product,
and their average. The classical decision problems in formal methods, such as
satisfiability, model checking, and synthesis, are generalized to search and optimization
problems in the quantitative setting. For example, model checking asks for the
quality in which a specification is satisfied, and synthesis returns a system
satisfying the specification with the highest quality. Reasoning about quality
gives rise to other natural questions, like the distance between specifications.
We formalize these basic questions and study them for LTL[F]. By extending the
automata-theoretic approach for LTL to a setting that takes quality into an account,
we are able to solve the above problems and show that reasoning about LTL[F] has
roughly the same complexity as reasoning about traditional LTL.'

text: A class of valued constraint satisfaction problems (VCSPs) is characterised
by a valued constraint language, a fixed set of cost functions on a finite domain.
An instance of the problem is specified by a sum of cost functions from the language
with the goal to minimise the sum. We study which classes of finite-valued languages
can be solved exactly by the basic linear programming relaxation (BLP). Thapper
and Živný showed [20] that if BLP solves the language then the language admits
a binary commutative fractional polymorphism. We prove that the converse is also
true. This leads to a necessary and a sufficient condition which can be checked
in polynomial time for a given language. In contrast, the previous necessary and
sufficient condition due to [20] involved infinitely many inequalities. More recently,
Thapper and Živný [21] showed (using, in particular, a technique introduced in
this paper) that core languages that do not satisfy our condition are NP-hard.
Taken together, these results imply that a finite-valued language can either be
solved using Linear Programming or is NP-hard.

text: "We propose a probabilistic model to infer supervised latent variables in\r\nthe
Hamming space from observed data. Our model allows simultaneous\r\ninference of
the number of binary latent variables, and their values. The\r\nlatent variables
preserve neighbourhood structure of the data in a sense\r\nthat objects in the
same semantic concept have similar latent values, and\r\nobjects in different
concepts have dissimilar latent values. We formulate\r\nthe supervised infinite
latent variable problem based on an intuitive\r\nprinciple of pulling objects
together if they are of the same type, and\r\npushing them apart if they are not.
We then combine this principle with a\r\nflexible Indian Buffet Process prior
on the latent variables. We show that\r\nthe inferred supervised latent variables
can be directly used to perform a\r\nnearest neighbour search for the purpose
of retrieval. We introduce a new\r\napplication of dynamically extending hash
codes, and show how to\r\neffectively couple the structure of the hash codes with
continuously\r\ngrowing structure of the neighbourhood preserving infinite latent
feature\r\nspace."

text: Establishing the spatiotemporal concentration profile of neurotransmitter
following synaptic vesicular release is essential for our understanding of inter-neuronal
communication. Such profile is a determinant of synaptic strength, short-term
plasticity and inter-synaptic crosstalk. Synaptically released glutamate has been
suggested to reach a few millimolar in concentration and last for <1 ms. The
synaptic cleft is often conceived as a single concentration compartment, whereas
a huge gradient likely exists. Modelling studies have attempted to describe this
gradient, but two key parameters, the number of glutamate in a vesicle (NGlu)
and its diffusion coefficient (DGlu) in the extracellular space, remained unresolved.
To determine this profile, the rat calyx of Held synapse at postnatal day 12-16
was studied where diffusion of glutamate occurs two-dimensionally and where quantification
of AMPA receptor distribution on individual postsynaptic specialization on medial
nucleus of the trapezoid body principal cells is possible using SDS-digested freeze-fracture
replica labelling. To assess the performance of these receptors as glutamate sensors,
a kinetic model of the receptors was constructed from outside-out patch recordings.
From here, we simulated synaptic responses and compared them with the EPSC recordings.
Combinations of NGlu and DGlu with an optimum of 7000 and 0.3 μm2 ms-1 reproduced
the data, suggesting slow diffusion. Further simulations showed that a single
vesicle does not saturate the synaptic receptors, and that glutamate spillover
does not affect the conductance amplitude at this synapse. Using the estimated
profile, we also evaluated how the number of multiple vesicle releases at individual
active zones affects the amplitude of postsynaptic signals.

text: P/Q-type voltage-dependent calcium channels play key roles in transmitter
release, integration of dendritic signals, generation of dendritic spikes, and
gene expression. High intracellular calcium concentration transient produced by
these channels is restricted to tens to hundreds of nanometers from the channels.
Therefore, precise localization of these channels along the plasma membrane was
long sought to decipher how each neuronal cell function is controlled. Here, we
analyzed the distribution of Cav2.1 subunit of the P/Q-type channel using highly
sensitive SDS-digested freeze-fracture replica labeling in the rat cerebellar
Purkinje cells. The labeling efficiency was such that the number of immunogold
particles in each parallel fiber active zone was comparable to that of functional
channels calculated from previous reports. Two distinct patterns of Cav2.1 distribution,
scattered and clustered, were found in Purkinje cells. The scattered Cav2.1 had
a somatodendritic gradient with the density of immunogold particles increasing
2.5-fold from soma to distal dendrites. The other population with 74-fold higher
density than the scattered particles was found within clusters of intramembrane
particles on the P-face of soma and primary dendrites. Both populations of Cav2.1
were found as early as P3 and increased in the second postnatal week to a mature
level. Using double immunogold labeling, we found that virtually all of the Cav2.1
clusters were colocalized with two types of calcium-activated potassium channels,
BK and SK2, with the nearest neighbor distance of 40∼nm. Calcium nanodomain created
by the opening of Cav2.1 channels likely activates the two channels that limit
the extent of depolarization.

text: The group III metabotropic glutamate (mGlu) receptors mGlu7 and mGlu8 are
receiving increased attention as potential novel therapeutic targets for anxiety
disorders. The effects mediated by these receptors appear to result from a complex
interplay of facilitatory and inhibitory actions at different brain sites in the
anxiety/fear circuits. To better understand the effect of mGlu7 and mGlu8 receptors
on extinction of contextual fear and their critical sites of action in the fear
networks, we focused on the amygdala. Direct injection into the basolateral complex
of the amygdala of the mGlu7 receptor agonist AMN082 facilitated extinction, whereas
the mGlu8 receptor agonist (S)-3,4-DCPG sustained freezing during the extinction
acquisition trial. We also determined at the ultrastructural level the synaptic
distribution of these receptors in the basal nucleus (BA) and intercalated cell
clusters (ITCs) of the amygdala. Both areas are thought to exert key roles in
fear extinction. We demonstrate that mGlu7 and mGlu8 receptors are located in
different presynaptic terminals forming both asymmetric and symmetric synapses,
and that they preferentially target neurons expressing mGlu1α receptors mostly
located around ITCs. In addition we show that mGlu7 and mGlu8 receptors were segregated
to different inputs to a significant extent. In particular, mGlu7a receptors were
primarily onto glutamatergic afferents arising from the BA or midline thalamic
nuclei, but not the medial prefrontal cortex (mPFC), as revealed by combined anterograde
tracing and pre-embedding electron microscopy. On the other hand, mGlu8a showed
a more restricted distribution in the BA and appeared absent from thalamic, mPFC
and intrinsic inputs. This segregation of mGlu7 and mGlu8 receptors in different
neuronal pathways of the fear circuit might explain the distinct effects on fear
extinction training observed with mGlu7 and mGlu8 receptor agonists.

text: Inhibitory parvalbumin-containing interneurons (PVIs) control neuronal discharge
and support the generation of theta- and gammafrequency oscillations in cortical
networks. Fast GABAergic input onto PVIs is crucial for their synchronization
and oscillatory entrainment, but the role of metabotropic GABAB receptors (GABABRs)
in mediating slow presynaptic and postsynaptic inhibition remains unknown. In
this study, we have combined high-resolution immunoelectron microscopy, whole-cell
patch-clamp recording, and computational modeling to investigate the subcellular
distribution and effects of GABABRs and their postsynaptic effector Kir3 channels
in rat hippocampal PVIs. Pre-embedding immunogold labeling revealed that the receptors
and channels localize at high levels to the extrasynaptic membrane of parvalbumin-immunoreactive
dendrites. Immunoreactivity forGABABRs was also present at lower levels on PVI
axon terminals. Whole-cell recordings further showed that synaptically released
GABA in response to extracellular stimulation evokes large GABABR-mediated slow
IPSCs in perisomatic-targeting (PT) PVIs, but only small or no currents in dendrite-targeting
(DT) PVIs. In contrast, paired recordings demonstrated that GABABR activation
results in presynaptic inhibition at the output synapses of both PT and DT PVIs,
but more strongly in the latter. Finally, computational analysis indicated that
GABAB IPSCs can phasically modulate the discharge of PT interneurons at theta
frequencies. In summary, our results show that GABABRs differentially mediate
slow presynaptic and postsynaptic inhibition in PVIs and can contribute to the
dynamic modulation of their activity during oscillations. Furthermore, these data
provide evidence for a compartment-specific molecular divergence of hippocampal
PVI subtypes, suggesting that activation of GABABRs may shift the balance between
perisomatic and dendritic inhibition.

text: We consider Hermitian and symmetric random band matrices H = (h xy ) in d⩾1
d ⩾ 1 dimensions. The matrix entries h xy , indexed by x,y∈(Z/LZ)d x , y ∈ ( Z
/ L Z ) d , are independent, centred random variables with variances sxy=E|hxy|2
s x y = E | h x y | 2 . We assume that s xy is negligible if |x − y| exceeds the
band width W. In one dimension we prove that the eigenvectors of H are delocalized
if W≫L4/5 W ≫ L 4 / 5 . We also show that the magnitude of the matrix entries
|Gxy|2 | G x y | 2 of the resolvent G=G(z)=(H−z)−1 G = G ( z ) = ( H - z ) - 1
is self-averaging and we compute E|Gxy|2 E | G x y | 2 . We show that, as L→∞
L → ∞ and W≫L4/5 W ≫ L 4 / 5 , the behaviour of E|Gxy|2 E | G x y | 2 is governed
by a diffusion operator whose diffusion constant we compute. Similar results are
obtained in higher dimensions.
