text: 'With the accelerated development of robot technologies, optimal control becomes
one of the central themes of research. In traditional approaches, the controller,
by its internal functionality, finds appropriate actions on the basis of the history
of sensor values, guided by the goals, intentions, objectives, learning schemes,
and so forth. The idea is that the controller controls the world---the body plus
its environment---as reliably as possible. This paper focuses on new lines of
self-organization for developmental robotics. We apply the recently developed
differential extrinsic synaptic plasticity to a muscle-tendon driven arm-shoulder
system from the Myorobotics toolkit. In the experiments, we observe a vast variety
of self-organized behavior patterns: when left alone, the arm realizes pseudo-random
sequences of different poses. By applying physical forces, the system can be entrained
into definite motion patterns like wiping a table. Most interestingly, after attaching
an object, the controller gets in a functional resonance with the object''s internal
dynamics, starting to shake spontaneously bottles half-filled with water or sensitively
driving an attached pendulum into a circular mode. When attached to the crank
of a wheel the neural system independently discovers how to rotate it. In this
way, the robot discovers affordances of objects its body is interacting with.'

text: The stimulus selectivity of synaptic currents in cortical neurons often shows
a co-tuning of excitation and inhibition, but the mechanisms that underlie the
emergence and plasticity of this co-tuning are not fully understood. Using a computational
model, we show that an interaction of excitatory and inhibitory synaptic plasticity
reproduces both the developmental and – when combined with a disinhibitory gate
– the adult plasticity of excitatory and inhibitory receptive fields in auditory
cortex. The co-tuning arises from inhibitory plasticity that balances excitation
and inhibition, while excitatory stimulus selectivity can result from two different
mechanisms. Inhibitory inputs with a broad stimulus tuning introduce a sliding
threshold as in Bienenstock-Cooper-Munro rules, introducing an excitatory stimulus
selectivity at the cost of a broader inhibitory receptive field. Alternatively,
input asymmetries can be amplified by synaptic competition. The latter leaves
any receptive field plasticity transient, a prediction we verify in recordings
in auditory cortex.

text: The Gag polyprotein of retroviruses drives immature virus assembly by forming
hexameric protein lattices. The assembly is primarily mediated by protein-protein
interactions between capsid (CA) domains and by interactions between nucleocapsid
(NC) domains and RNA. Specific interactions between NC and the viral RNA are required
for genome packaging. Previously reported cryoelectron microscopy analysis of
immature Mason-Pfizer monkey virus (M-PMV) particles suggested that a basic region
(residues RKK) in CA may serve as an additional binding site for nucleic acids.
Here, we have introduced mutations into the RKK region in both bacterial and proviral
M-PMV vectors and have assessed their impact on M-PMV assembly, structure, RNA
binding, budding/release, nuclear trafficking, and infectivity using in vitro
and in vivo systems. Our data indicate that the RKK region binds and structures
nucleic acid that serves to promote virus particle assembly in the cytoplasm.
Moreover, the RKK region appears to be important for recruitment of viral genomic
RNA into Gag particles, and this function could be linked to changes in nuclear
trafficking. Together these observations suggest that in M-PMV, direct interactions
between CA and nucleic acid play important functions in the late stages of the
viral life cycle.

text: Immature HIV-1 assembles at and buds from the plasma membrane before proteolytic
cleavage of the viral Gag polyprotein induces structural maturation. Maturation
can be blocked by maturation inhibitors (MIs), thereby abolishing infectivity.
The CA (capsid) and SP1 (spacer peptide 1) region of Gag is the key regulator
of assembly and maturation and is the target of MIs.We applied optimized cryo-electron
tomography and subtomogram averaging to resolve this region within assembled immature
HIV-1 particles at 3.9 angstrom resolution and built an atomic model. The structure
reveals a network of intra- And intermolecular interactions mediating immature
HIV-1 assembly. The proteolytic cleavage site between CA and SP1 is inaccessible
to protease.We suggest that MIs prevent CA-SP1 cleavage by stabilizing the structure,
and MI resistance develops by destabilizing CA-SP1.

text: "Most entropy notions H(.) like Shannon or min-entropy satisfy a chain rule
stating that for random variables X,Z, and A we have H(X|Z,A)≥H(X|Z)−|A|. That
is, by conditioning on A the entropy of X can decrease by at most the bitlength
|A| of A. Such chain rules are known to hold for some computational entropy notions
like Yao’s and unpredictability-entropy. For HILL entropy, the computational analogue
of min-entropy, the chain rule is of special interest and has found many applications,
including leakage-resilient cryptography, deterministic encryption, and memory
delegation. These applications rely on restricted special cases of the chain rule.
Whether the chain rule for conditional HILL entropy holds in general was an open
problem for which we give a strong negative answer: we construct joint distributions
(X,Z,A), where A is a distribution over a single bit, such that the HILL entropy
H HILL (X|Z) is large but H HILL (X|Z,A) is basically zero.\r\n\r\nOur counterexample
just makes the minimal assumption that NP⊈P/poly. Under the stronger assumption
that injective one-way function exist, we can make all the distributions efficiently
samplable.\r\n\r\nFinally, we show that some more sophisticated cryptographic
objects like lossy functions can be used to sample a distribution constituting
a counterexample to the chain rule making only a single invocation to the underlying
object."

text: 'Exponential varieties arise from exponential families in statistics. These
real algebraic varieties have strong positivity and convexity properties, familiar
from toric varieties and their moment maps. Among them are varieties of inverses
of symmetric matrices satisfying linear constraints. This class includes Gaussian
graphical models. We develop a general theory of exponential varieties. These
are derived from hyperbolic polynomials and their integral representations. We
compare the multidegrees and ML degrees of the gradient map for hyperbolic polynomials. '

text: Plants have the ability to continously generate new organs by maintaining
populations of stem cells throught their lives. The shoot apical meristem (SAM)
provides a stable environment for the maintenance of stem cells. All cells inside
the SAM divide, yet boundaries and patterns are maintained. Experimental evidence
indicates that patterning is independent of cell lineage, thus a dynamic self-regulatory
mechanism is required. A pivotal role in the organization of the SAM is played
by the WUSCHEL gene (WUS). An important question in this regard is that how WUS
expression is positioned in the SAM via a cell-lineage independent signaling mechanism.
In this study we demonstrate via mathematical modeling that a combination of an
inhibitor of the Cytokinin (CK) receptor, Arabidopsis histidine kinase 4 (AHK4)
and two morphogens originating from the top cell layer, can plausibly account
for the cell lineage-independent centering of WUS expression within SAM. Furthermore,
our laser ablation and microsurgical experiments support the hypothesis that patterning
in SAM occurs at the level of CK reception and signaling. The model suggests that
the interplay between CK signaling, WUS/CLV feedback loop and boundary signals
can account for positioning of the WUS expression, and provides directions for
further experimental investigation.

and Y. Deb for advice regarding the laser ablation experiments. We specially thank
Thomas Laux for stimulating discussions and support in the initial phase of this

text: In this article the notion of metabolic turnover is revisited in the light
of recent results of out-of-equilibrium thermodynamics. By means of Monte Carlo
methods we perform an exact sampling of the enzymatic fluxes in a genome scale
metabolic network of E. Coli in stationary growth conditions from which we infer
the metabolites turnover times. However the latter are inferred from net fluxes,
and we argue that this approximation is not valid for enzymes working nearby thermodynamic
equilibrium. We recalculate turnover times from total fluxes by performing an
energy balance analysis of the network and recurring to the fluctuation theorem.
We find in many cases values one of order of magnitude lower, implying a faster
picture of intermediate metabolism.

text: We review recent results concerning the mathematical properties of the Bardeen-Cooper-Schrieffer
(BCS) functional of superconductivity, which were obtained in a series of papers,
partly in collaboration with R. Frank, E. Hamza, S. Naboko, and J. P. Solovej.
Our discussion includes, in particular, an investigation of the critical temperature
for a general class of interaction potentials, as well as a study of its dependence
on external fields. We shall explain how the Ginzburg-Landau model can be derived
from the BCS theory in a suitable parameter regime.

text: Rhythms with time scales of multiple cycles per second permeate the mammalian
brain, yet neuroscientists are not certain of their functional roles. One leading
idea is that coherent oscillation between two brain regions facilitates the exchange
of information between them. In rats, the hippocampus and the vibrissal sensorimotor
system both are characterized by rhythmic oscillation in the theta range, 5–12
Hz. Previous work has been divided as to whether the two rhythms are independent
or coherent. To resolve this question, we acquired three measures from rats—whisker
motion, hippocampal local field potential (LFP), and barrel cortex unit firing—during
a whisker-mediated texture discrimination task and during control conditions (not
engaged in a whisker-mediated memory task). Compared to control conditions, the
theta band of hippocampal LFP showed a marked increase in power as the rats approached
and then palpated the texture. Phase synchronization between whisking and hippocampal
LFP increased by almost 50% during approach and texture palpation. In addition,
a greater proportion of barrel cortex neurons showed firing that was phase-locked
to hippocampal theta while rats were engaged in the discrimination task. Consistent
with a behavioral consequence of phase synchronization, the rats identified the
texture more rapidly and with lower error likelihood on trials in which there
was an increase in theta-whisking coherence at the moment of texture palpation.
These results suggest that coherence between the whisking rhythm, barrel cortex
firing, and hippocampal LFP is augmented selectively during epochs in which the
rat collects sensory information and that such coherence enhances the efficiency
of integration of stimulus information into memory and decision-making centers.

text: Branching morphogenesis of the epithelial ureteric bud forms the renal collecting
duct system and is critical for normal nephron number, while low nephron number
is implicated in hypertension and renal disease. Ureteric bud growth and branching
requires GDNF signaling from the surrounding mesenchyme to cells at the ureteric
bud tips, via the Ret receptor tyrosine kinase and coreceptor Gfrα1; Ret signaling
up-regulates transcription factors Etv4 and Etv5, which are also critical for
branching. Despite extensive knowledge of the genetic control of these events,
it is not understood, at the cellular level, how renal branching morphogenesis
is achieved or how Ret signaling influences epithelial cell behaviors to promote
this process. Analysis of chimeric embryos previously suggested a role for Ret
signaling in promoting cell rearrangements in the nephric duct, but this method
was unsuited to study individual cell behaviors during ureteric bud branching.
Here, we use Mosaic Analysis with Double Markers (MADM), combined with organ culture
and time-lapse imaging, to trace the movements and divisions of individual ureteric
bud tip cells. We first examine wild-type clones and then Ret or Etv4 mutant/wild-type
clones in which the mutant and wild-type sister cells are differentially and heritably
marked by green and red fluorescent proteins. We find that, in normal kidneys,
most individual tip cells behave as self-renewing progenitors, some of whose progeny
remain at the tips while others populate the growing UB trunks. In Ret or Etv4
MADM clones, the wild-type cells generated at a UB tip are much more likely to
remain at, or move to, the new tips during branching and elongation, while their
Ret−/− or Etv4−/− sister cells tend to lag behind and contribute only to the trunks.
By tracking successive mitoses in a cell lineage, we find that Ret signaling has
little effect on proliferation, in contrast to its effects on cell movement. Our
results show that Ret/Etv4 signaling promotes directed cell movements in the ureteric
bud tips, and suggest a model in which these cell movements mediate branching
morphogenesis.

text: To induce adaptive immunity, dendritic cells (DCs) migrate through afferent
lymphatic vessels (LVs) to draining lymph nodes (dLNs). This process occurs in
several consecutive steps. Upon entry into lymphatic capillaries, DCs first actively
crawl into downstream collecting vessels. From there, they are next passively
and rapidly transported to the dLN by lymph flow. Here, we describe a role for
the chemokine CCL21 in intralymphatic DC crawling. Performing time-lapse imaging
in murine skin, we found that blockade of CCL21-but not the absence of lymph flow-completely
abolished DC migration from capillaries toward collecting vessels and reduced
the ability of intralymphatic DCs to emigrate from skin. Moreover, we found that
in vitro low laminar flow established a CCL21 gradient along lymphatic endothelial
monolayers, thereby inducing downstream-directed DC migration. These findings
reveal a role for intralymphatic CCL21 in promoting DC trafficking to dLNs, through
the formation of a flow-induced gradient.

text: We study the ground state of a trapped Bose gas, starting from the full many-body
Schrödinger Hamiltonian, and derive the non-linear Schrödinger energy functional
in the limit of a large particle number, when the interaction potential converges
slowly to a Dirac delta function. Our method is based on quantitative estimates
on the discrepancy between the full many-body energy and its mean-field approximation
using Hartree states. These are proved using finite dimensional localization and
a quantitative version of the quantum de Finetti theorem. Our approach covers
the case of attractive interactions in the regime of stability. In particular,
our main new result is a derivation of the 2D attractive non-linear Schrödinger
ground state.

text: To sustain a lifelong ability to initiate organs, plants retain pools of undifferentiated
cells with a preserved prolif eration capacity. The root pericycle represents
a unique tissue with conditional meristematic activity, and its tight control
determines initiation of lateral organs. Here we show that the meristematic activity
of the pericycle is constrained by the interaction with the adjacent endodermis.
Release of these restraints by elimination of endo dermal cells by single-cell
ablation triggers the pericycle to re-enter the cell cycle. We found that endodermis
removal substitutes for the phytohormone auxin-dependent initiation of the pericycle
meristematic activity. However, auxin is indispensable to steer the cell division
plane orientation of new organ-defining divisions. We propose a dual, spatiotemporally
distinct role for auxin during lateral root initiation. In the endodermis, auxin
releases constraints arising from cell-to-cell interactions that compromise the
pericycle meristematic activity, whereas, in the pericycle, auxin defines the
orientation of the cell division plane to initiate lateral roots.

text: We introduce a new method for deriving the time-dependent Hartree or Hartree-Fock
equations as an effective mean-field dynamics from the microscopic Schrödinger
equation for fermionic many-particle systems in quantum mechanics. The method
is an adaption of the method used in Pickl (Lett. Math. Phys. 97 (2) 151–164 2011)
for bosonic systems to fermionic systems. It is based on a Gronwall type estimate
for a suitable measure of distance between the microscopic solution and an antisymmetrized
product state. We use this method to treat a new mean-field limit for fermions
with long-range interactions in a large volume. Some of our results hold for singular
attractive or repulsive interactions. We can also treat Coulomb interaction assuming
either a mild singularity cutoff or certain regularity conditions on the solutions
to the Hartree(-Fock) equations. In the considered limit, the kinetic and interaction
energy are of the same order, while the average force is subleading. For some
interactions, we prove that the Hartree(-Fock) dynamics is a more accurate approximation
than a simpler dynamics that one would expect from the subleading force. With
our method we also treat the mean-field limit coupled to a semiclassical limit,
which was discussed in the literature before, and we recover some of the previous
results. All results hold for initial data close (but not necessarily equal) to
antisymmetrized product states and we always provide explicit rates of convergence.

text: Turbulence is one of the most frequently encountered non-equilibrium phenomena
in nature, yet characterizing the transition that gives rise to turbulence in
basic shear flows has remained an elusive task. Although, in recent studies, critical
points marking the onset of sustained turbulence have been determined for several
such flows, the physical nature of the transition could not be fully explained.
In extensive experimental and computational studies we show for the example of
Couette flow that the onset of turbulence is a second-order phase transition and
falls into the directed percolation universality class. Consequently, the complex
laminar–turbulent patterns distinctive for the onset of turbulence in shear flows
result from short-range interactions of turbulent domains and are characterized
by universal critical exponents. More generally, our study demonstrates that even
high-dimensional systems far from equilibrium such as turbulence exhibit universality
at onset and that here the collective dynamics obeys simple rules.

text: The two-photon 1s2 2s 2p 3P0 1s22s2 1S0 transition in berylliumlike ions is
theoretically investigated within a fully relativistic framework and a second-order
perturbation theory. We focus our analysis on how electron correlation, as well
as the negative-energy spectrum, can affect the forbidden E1M1 decay rate. For
this purpose, we include the electronic correlation via an effective local potential
and within a single configuration-state model. Due to its experimental interest,
evaluations of decay rates are performed for berylliumlike xenon and uranium.
We find that the negative-energy contribution can be neglected at the present
level of accuracy in the evaluation of the decay rate. On the other hand, if contributions
of electronic correlation are not carefully taken into account, it may change
the lifetime of the metastable state by up to 20%. By performing a full-relativistic
jj-coupling calculation, we found a decrease of the decay rate by two orders of
magnitude compared to non-relativistic LS-coupling calculations, for the selected
heavy ions.

text: The inference of demographic history from genome data is hindered by a lack
of efficient computational approaches. In particular, it has proved difficult
to exploit the information contained in the distribution of genealogies across
the genome. We have previously shown that the generating function (GF) of genealogies
can be used to analytically compute likelihoods of demographic models from configurations
of mutations in short sequence blocks (Lohse et al. 2011). Although the GF has
a simple, recursive form, the size of such likelihood calculations explodes quickly
with the number of individuals and applications of this framework have so far
been mainly limited to small samples (pairs and triplets) for which the GF can
be written by hand. Here we investigate several strategies for exploiting the
inherent symmetries of the coalescent. In particular, we show that the GF of genealogies
can be decomposed into a set of equivalence classes that allows likelihood calculations
from nontrivial samples. Using this strategy, we automated blockwise likelihood
calculations for a general set of demographic scenarios in Mathematica. These
histories may involve population size changes, continuous migration, discrete
divergence, and admixture between multiple populations. To give a concrete example,
we calculate the likelihood for a model of isolation with migration (IM), assuming
two diploid samples without phase and outgroup information. We demonstrate the
new inference scheme with an analysis of two individual butterfly genomes from
the sister species Heliconius melpomene rosina and H. cydno.
