text: 'The activity of hippocampal pyramidal cells reflects both the current position
of the animal and information related to its current behavior. Here we investigated
whether single hippocampal neurons can encode several independent features defining
trials during a memory task. We also tested whether task-related information is
represented by partial remapping of the place cell population or, instead, via
firing rate modulation of spatially stable place cells. To address these two questions,
the activity of hippocampal neurons was recorded in rats performing a conditional
discrimination task on a modified T-maze in which the identity of a food reward
guided behavior. When the rat was on the central arm of the maze, the firing rate
of pyramidal cells changed depending on two independent factors: (1) the identity
of the food reward given to the animal and (2) the previous location of the animal
on the maze. Importantly, some pyramidal cells encoded information relative to
both factors. This trial-type specific and retrospective coding did not interfere
with the spatial representation of the maze: hippocampal cells had stable place
fields and their theta-phase precession profiles were unaltered during the task,
indicating that trial-related information was encoded via rate remapping. During
error trials, encoding of both trial-related information and spatial location
was impaired. Finally, we found that pyramidal cells also encode trial-related
information via rate remapping during the continuous version of the rewarded alternation
task without delays. These results suggest that hippocampal neurons can encode
several task-related cognitive aspects via rate remapping.'

text: We study maximum likelihood estimation in Gaussian graphical models from a
geometric point of view. An algebraic elimination criterion allows us to find
exact lower bounds on the number of observations needed to ensure that the maximum
likelihood estimator (MLE) exists with probability one. This is applied to bipartite
graphs, grids and colored graphs. We also study the ML degree, and we present
the first instance of a graph for which the MLE exists with probability one, even
when the number of observations equals the treewidth.
acknowledgement: "I wish to thank Bernd Sturmfels for many helpful discus- sions and

text: 'Background: The outcome of male-male competition can be predicted from the
relative fighting qualities of the opponents, which often depend on their age.
In insects, freshly emerged and still sexually inactive males are morphologically
indistinct from older, sexually active males. These young inactive males may thus
be easy targets for older males if they cannot conceal themselves from their attacks.
The ant Cardiocondyla obscurior is characterised by lethal fighting between wingless
(" ergatoid" ) males. Here, we analyse for how long young males are
defenceless after eclosion, and how early adult males can detect the presence
of rival males.Results: We found that old ergatoid males consistently won fights
against ergatoid males younger than two days. Old males did not differentiate
between different types of unpigmented pupae several days before emergence, but
had more frequent contact to ready-to-eclose pupae of female sexuals and winged
males than of workers and ergatoid males. In rare cases, old ergatoid males displayed
alleviated biting of pigmented ergatoid male pupae shortly before adult eclosion,
as well as copulation attempts to dark pupae of female sexuals and winged males.
Ergatoid male behaviour may be promoted by a closer similarity of the chemical
profile of ready-to-eclose pupae to the profile of adults than that of young pupae
several days prior to emergence.Conclusion: Young ergatoid males of C. obscurior
would benefit greatly by hiding their identity from older, resident males, as
they are highly vulnerable during the first two days of their adult lives. In
contrast to the winged males of the same species, which are able to prevent ergatoid
male attacks by chemical female mimicry, young ergatoids do not seem to be able
to produce a protective chemical profile. Conflicts in male-male competition between
ergatoid males of different age thus seem to be resolved in favour of the older
males. This might represent selection at the colony level rather than the individual
level. © 2012 Cremer et al.; licensee BioMed Central Ltd.'

text: The choice of summary statistics is a crucial step in approximate Bayesian
computation (ABC). Since statistics are often not sufficient, this choice involves
a trade-off between loss of information and reduction of dimensionality. The latter
may increase the efficiency of ABC. Here, we propose an approach for choosing
summary statistics based on boosting, a technique from the machine learning literature.
We consider different types of boosting and compare them to partial least squares
regression as an alternative. To mitigate the lack of sufficiency, we also propose
an approach for choosing summary statistics locally, in the putative neighborhood
of the true parameter value. We study a demographic model motivated by the re-introduction
of Alpine ibex (Capra ibex) into the Swiss Alps. The parameters of interest are
the mean and standard deviation across microsatellites of the scaled ancestral
mutation rate (θanc = 4 Ne u), and the proportion of males obtaining access to
matings per breeding season (ω). By simulation, we assess the properties of the
posterior distribution obtained with the various methods. According to our criteria,
ABC with summary statistics chosen locally via boosting with the L2-loss performs
best. Applying that method to the ibex data, we estimate θanc ≈ 1.288, and find
that most of the variation across loci of the ancestral mutation rate u is between
7.7×10−4 and 3.5×10−3 per locus per generation. The proportion of males with access
to matings is estimated to ω ≈ 0.21, which is in good agreement with recent independent
estimates.

text: 'Zebra finches are an ubiquitous model system for the study of vocal learning
in animal communication. Their song has been well described, but its possible
function(s) in social communication are only partly understood. The so-called
‘directed song’ is a high-intensity, high-performance song given during courtship
in close proximity to the female, which is known to mediate mate choice and mating.
However, this singing mode constitutes only a fraction of zebra finch males’ prolific
song output. Potential communicative functions of their second, ‘undirected’ singing
mode remain unresolved in the face of contradicting reports of both facilitating
and inhibiting effects of social company on singing. We addressed this issue by
experimentally manipulating social contexts in a within-subject design, comparing
a solo versus male or female only company condition, each lasting for 24 hours.
Males’ total song output was significantly higher when a conspecific was in audible
and visible distance than when they were alone. Male and female company had an
equally facilitating effect on song output. Our findings thus indicate that singing
motivation is facilitated rather than inhibited by social company, suggesting
that singing in zebra finches might function both in inter- and intrasexual communication. '

text: "We construct a perfectly binding string commitment scheme whose security
is based on the learning parity with noise (LPN) assumption, or equivalently,
the hardness of decoding random linear codes. Our scheme not only allows for a
simple and efficient zero-knowledge proof of knowledge for committed values (essentially
a Σ-protocol), but also for such proofs showing any kind of relation amongst committed
values, i.e. proving that messages m_0,...,m_u, are such that m_0=C(m_1,...,m_u)
for any circuit C.\r\n\r\nTo get soundness which is exponentially small in a security
parameter t, and when the zero-knowledge property relies on the LPN problem with
secrets of length l, our 3 round protocol has communication complexity O(t|C|l
log(l)) and computational complexity of O(t|C|l) bit operations. The hidden constants
are small, and the computation consists mostly of computing inner products of
bit-vectors."
acknowledgement: "We are grateful to Petros Mol for helpful discussions on the reduction
for the hardness of the xLPN problem.\r\n"

text: "The coupling between presynaptic Ca^(2+) channels and Ca^(2+) sensors of
exocytosis is a key determinant of synaptic transmission. Evoked release from
parvalbumin (PV)-expressing interneurons is triggered by nanodomain coupling of
P/Q-type Ca^(2+) channels, whereas release from cholecystokinin (CCK)-containing
interneurons is generated by microdomain coupling of N-type channels. Nanodomain
coupling has several functional advantages, including speed and efficacy of transmission.
One potential disadvantage is that stochastic\r\nopening of presynaptic Ca^(2+)
channels may trigger spontaneous transmitter release. We addressed this possibility
in rat hippocampal\r\ngranule cells, which receive converging inputs from different
inhibitory sources. Both reduction of extracellular Ca^(2+) concentration and
the unselective Ca^(2+) channel blocker Cd^(2+) reduced the frequency of miniature
IPSCs (mIPSCs) in granule cells by ~50%, suggesting that the opening of presynaptic
Ca^(2+) channels contributes to spontaneous release. Application of the selective
P/Q-type Ca^(2+) channel blocker\r\nω-agatoxin IVa had no detectable effects,
whereas both the N-type blocker ω-conotoxin GVIa and the L-type blocker nimodipine
reduced\r\nmIPSC frequency. Furthermore, both the fast Ca^(2+) chelator BAPTA-AM
and the slow chelator EGTA-AM reduced the mIPSC frequency,\r\nsuggesting that
Ca^(2+)-dependent spontaneous release is triggered by microdomain rather than
nanodomain coupling. The CB_(1) receptor\r\nagonist WIN 55212-2 also decreased
spontaneous release; this effect was occluded by prior application of ω-conotoxin
GVIa, suggesting that a major fraction of Ca^(2+)-dependent spontaneous release
was generated at the terminals of CCK-expressing interneurons. Tonic inhibition
generated by spontaneous opening of presynaptic N- and L-type Ca^(2+) channels
may be important for hippocampal information processing.\r\n"

text: Morphogen gradients regulate the patterning and growth of many tissues, hence
a key question is how they are established and maintained during development.
Theoretical descriptions have helped to explain how gradient shape is controlled
by the rates of morphogen production, spreading and degradation. These effective
rates have been measured using fluorescence recovery after photobleaching (FRAP)
and photoactivation. To unravel which molecular events determine the effective
rates, such tissue-level assays have been combined with genetic analysis, high-resolution
assays, and models that take into account interactions with receptors, extracellular
components and trafficking. Nevertheless, because of the natural and experimental
data variability, and the underlying assumptions of transport models, it remains
challenging to conclusively distinguish between cellular mechanisms.

text: 'We study the task of interactive semantic labeling of a segmentation hierarchy.
To this end we propose a framework interleaving two components: an automatic labeling
step, based on a Conditional Random Field whose dependencies are defined by the
inclusion tree of the segmentation hierarchy, and an interaction step that integrates
incremental input from a human user. Evaluated on two distinct datasets, the proposed
interactive approach efficiently integrates human interventions and illustrates
the advantages of structured prediction in an interactive framework. '

text: Growth and development are coordinated by an array of intercellular communications.
Known plant signaling molecules include phytohormones and hormone peptides. Although
both classes can be implicated in the same developmental processes, little is
known about the interplay between phytohormone action and peptide signaling within
the cellular microenvironment. We show that genes coding for small secretory peptides,
designated GOLVEN (GLV), modulate the distribution of the phytohormone auxin.
The deregulation of the GLV function impairs the formation of auxin gradients
and alters the reorientation of shoots and roots after a gravity stimulus. Specifically,
the GLV signal modulates the trafficking dynamics of the auxin efflux carrier
PIN-FORMED2 involved in root tropic responses and meristem organization. Our work
links the local action of secretory peptides with phytohormone transport. Root
growth factor (RGF) or GOLVEN (GLV) secreted peptides have previously been implicated
in meristem regulation. Whitford et al. now show that RGF/GLV peptides induce
rapid relocalization of the auxin efflux regulator PIN2, regulate auxin gradients,
and modulate auxin-dependent root responses to specific stimuli.

text: Receptor-mediated endocytosis is an integral part of signal transduction as
it mediates signal attenuation and provides spatial and temporal dimensions to
signaling events. One of the best-studied leucine-rich repeat receptor-like kinases
in plants, BRASSINOSTEROID INSENSITIVE 1 (BRI1), perceives its ligand, the brassinosteroid
(BR) hormone, at the cell surface and is constitutively endocytosed. However,
the importance of endocytosis for BR signaling remains unclear. Here we developed
a bioactive, fluorescent BR analog, Alexa Fluor 647-castasterone (AFCS), and visualized
the endocytosis of BRI1-AFCS complexes in living Arabidopsis thaliana cells. Impairment
of endocytosis dependent on clathrin and the guanine nucleotide exchange factor
for ARF GTPases (ARF-GEF) GNOM enhanced BR signaling by retaining active BRI1-ligand
complexes at the plasma membrane. Increasing the trans-Golgi network/early endosome
pool of BRI1-BR complexes did not affect BR signaling. Our findings provide what
is to our knowledge the first visualization of receptor-ligand complexes in plants
and reveal clathrin-and ARF-GEF-dependent endocytic regulation of BR signaling
from the plasma membrane.

Gradients of the plant hormone auxin, which depend on its active intercellular transport, are crucial for the maintenance of root meristematic activity. This directional transport is largely orchestrated by a complex interaction of specific influx and efflux carriers that mediate the auxin flow into and out of cells, respectively. Besides these transport proteins, plant-specific polyphenolic compounds knownasflavonols have beenshownto act as endogenous regulators of auxin transport. However, only limited information is available on how flavonol synthesis is developmentally regulated. Using reduction-of-function and overexpression approaches in parallel, we demonstrate that the WRKY23 transcription factor is needed for proper root growth and development by stimulating the local biosynthesis of flavonols. The expression of WRKY23 itself is controlled by auxin through the AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 transcriptional response pathway. Our results suggest a model in which WRKY23 is part of a transcriptional feedback loop of auxin on its own transport through local regulation of flavonol biosynthesis.

text: The phytohormone auxin acts as a prominent signal, providing, by its local
accumulation or depletion in selected cells, a spatial and temporal reference
for changes in the developmental program. The distribution of auxin depends on
both auxin metabolism (biosynthesis, conjugation and degradation) and cellular
auxin transport. We identified in silico a novel putative auxin transport facilitator
family, called PIN-LIKES (PILS). Here we illustrate that PILS proteins are required
for auxin-dependent regulation of plant growth by determining the cellular sensitivity
to auxin. PILS proteins regulate intracellular auxin accumulation at the endoplasmic
reticulum and thus auxin availability for nuclear auxin signalling. PILS activity
affects the level of endogenous auxin indole-3-acetic acid (IAA), presumably via
intracellular accumulation and metabolism. Our findings reveal that the transport
machinery to compartmentalize auxin within the cell is of an unexpected molecular
complexity and demonstrate this compartmentalization to be functionally important
for a number of developmental processes.

text: Cell polarization via asymmetrical distribution of structures or molecules
is essential for diverse cellular functions and development of organisms, but
how polarity is developmentally controlled has been poorly understood. In plants,
the asymmetrical distribution of the PIN-FORMED (PIN) proteins involved in the
cellular efflux of the quintessential phytohormone auxin plays a central role
in developmental patterning, morphogenesis, and differential growth. Recently
we showed that auxin promotes cell interdigitation by activating the Rho family
ROP GTPases in leaf epidermal pavement cells. Here we found that auxin activation
of the ROP2 signaling pathway regulates the asymmetric distribution of PIN1 by
inhibiting its endocytosis. ROP2 inhibits PIN1 endocytosis via the accumulation
of cortical actin microfilaments induced by the ROP2 effector protein RIC4. Our
findings suggest a link between the developmental auxin signal and polar PIN1
distribution via Rho-dependent cytoskeletal reorganization and reveal the conservation
of a design principle for cell polarization that is based on Rho GTPase-mediated
inhibition of endocytosis.

text: "We present an approach for artist-directed animation of liquids using multiple
levels of control over the simulation, ranging from the overall tracking of desired
shapes to highly detailed secondary effects such as dripping streams, separating
sheets of fluid, surface waves and ripples. The first portion of our technique
is a volume preserving morph that allows the animator to produce a plausible fluid-like
motion from a sparse set of control meshes. By rasterizing the resulting control
meshes onto the simulation grid, the mesh velocities act as boundary conditions
during the projection step of the fluid simulation. We can then blend this motion
together with uncontrolled fluid velocities to achieve a more relaxed control
over the fluid that captures natural inertial effects. Our method can produce
highly detailed liquid surfaces with control over sub-grid details by using a
mesh-based surface tracker on top of a coarse grid-based fluid simulation. We
can create ripples and waves on the fluid surface attracting the surface mesh
to the control mesh with spring-like forces and also by running a wave simulation
over the surface mesh. Our video results demonstrate how our control scheme can
be used to create animated characters and shapes that are made of water.\r\n"

text: We present a method for recovering a temporally coherent, deforming triangle
mesh with arbitrarily changing topology from an incoherent sequence of static
closed surfaces. We solve this problem using the surface geometry alone, without
any prior information like surface templates or velocity fields. Our system combines
a proven strategy for triangle mesh improvement, a robust multi-resolution non-rigid
registration routine, and a reliable technique for changing surface mesh topology.
We also introduce a novel topological constraint enforcement algorithm to ensure
that the output and input always have similar topology. We apply our technique
to a series of diverse input data from video reconstructions, physics simulations,
and artistic morphs. The structured output of our algorithm allows us to efficiently
track information like colors and displacement maps, recover velocity information,
and solve PDEs on the mesh as a post process.

text: 'Since Darwin''s pioneering research on plant reproductive biology (e.g. Darwin
1877), understanding the mechanisms maintaining the diverse sexual strategies
of plants has remained an important challenge for evolutionary biologists. In
some species, populations are sexually polymorphic and contain two or more mating
morphs (sex phenotypes). Differences in morphology or phenology among the morphs
influence patterns of non-random mating. In these populations, negative frequency-dependent
selection arising from disassortative (intermorph) mating is usually required
for the evolutionary maintenance of sexual polymorphism, but few studies have
demonstrated the required patterns of non-random mating. In the current issue
of Molecular Ecology, Shang (2012) make an important contribution to our understanding
of how disassortative mating influences sex phenotype ratios in Acer pictum subsp.
mono (painted maple), a heterodichogamous, deciduous tree of eastern China. They
monitored sex expression in 97 adults and used paternity analysis of open-pollinated
seed to examine disassortative mating among three sex phenotypes. Using a deterministic
''pollen transfer'' model, Shang et al. present convincing evidence that differences
in the degree of disassortative mating in progeny arrays of the sex phenotypes
can explain their uneven frequencies in the adult population. This study provides
a useful example of how the deployment of genetic markers, demographic monitoring
and modelling can be integrated to investigate the maintenance of sexual diversity
in plants. '

text: Voltage-activated Ca(2+) channels (VACCs) mediate Ca(2+) influx to trigger
action potential-evoked neurotransmitter release, but the mechanism by which Ca(2+)
regulates spontaneous transmission is unclear. We found that VACCs are the major
physiological triggers for spontaneous release at mouse neocortical inhibitory
synapses. Moreover, despite the absence of a synchronizing action potential, we
found that spontaneous fusion of a GABA-containing vesicle required the activation
of multiple tightly coupled VACCs of variable type.
