text: Auctions are widely used on the Web. Applications range from internet advertising
to platforms such as eBay. In most of these applications the auctions in use are
single/multi-item auctions with unit demand. The main drawback of standard mechanisms
for this type of auctions, such as VCG and GSP, is the limited expressiveness
that they offer to the bidders. The General Auction Mechanism (GAM) of [1] is
taking a first step towards addressing the problem of limited expressiveness by
computing a bidder optimal, envy free outcome for linear utility functions with
identical slopes and a single discontinuity per bidder-item pair. We show that
in many practical situations this does not suffice to adequately model the preferences
of the bidders, and we overcome this problem by presenting the first mechanism
for piece-wise linear utility functions with non-identical slopes and multiple
discontinuities. Our mechanism runs in polynomial time. Like GAM it is incentive
compatible for inputs that fulfill a certain non-degeneracy requirement, but our
requirement is more general than the requirement of GAM. For discontinuous utility
functions that are non-degenerate as well as for continuous utility functions
the outcome of our mechanism is a competitive equilibrium. We also show how our
mechanism can be used to compute approximately bidder optimal, envy free outcomes
for a general class of continuous utility functions via piece-wise linear approximation.
Finally, we prove hardness results for even more expressive settings.

text: Temperature data from three Automatic Weather Stations and twelve Temperature
Loggers are used to investigate the spatiotemporal variability of temperature
over a glacier, its main atmospheric controls, the suitability of extrapolation
techniques and their effect on melt modeling. We use data collected on Juncal
Norte Glacier, central Chile, during one ablation season. We examine temporal
and spatial variability in lapse rates (LRs), together with alternative statistical
interpolation methods. The main control over the glacier thermal regime is the
development of a katabatic boundary layer (KBL). Katabatic wind occurs at night
and in the morning and is eroded in the afternoon. LRs reveal strong diurnal variability,
with steeper LRs during the day when the katabatic wind weakens and shallower
LRs during the night and morning. We suggest that temporally variable LRs should
be used to account for the observed change. They tend to be steeper than equivalent
constant LRs, and therefore result in a reduction in simulated melt compared to
use of constant LRs when extrapolating from lower to higher elevations. In addition
to the temporal variability, the temperature-elevation relationship varies also
in space. Differences are evident between local LRs and including such variability
in melt modeling affects melt simulations. Extrapolation methods based on the
spatial variability of the observations after removal of the elevation trend,
such as Inverse Distance Weighting or Kriging, do not seem necessary for simulations
of gridded temperature data over a glacier.

text: Physically based hydrological models describe natural processes more accurately
than conceptual models but require extensive data sets to produce accurate results.
To identify the value of different data sets for improving the performance of
the distributed hydrological model TOPKAPI we combine a multivariable validation
technique with Monte Carlo simulations. The study is carried out in the snow and
ice-dominated Rhonegletscher basin, as these types of mountainous basins are generally
the most critical with respect to data availability and sensitivity to climate
fluctuations. Each observational data set is used individually and in combination
with the other data sets to determine a subset of best parameter combinations
out of 10,000 Monte Carlos runs performed with randomly generated parameter sets.
We validate model results against discharge, glacier mass balance, and satellite
snow cover images for a 14 year time period (1994–2007). While the use of all
data sets combined provides the best overall model performance (defined by the
concurrent best agreement of simulated discharge, snow cover and mass balance
with their respective measurements), the use of one or two variables for constraining
the model results in poorer performance. Using only one data set for constraining
the model glacier mass balance proved to be the most efficient observation leading
to the best overall model performance. Our main result is that a combination of
discharge and satellite snow cover images is best for improving model performance,
since the volumetric information of discharge data and the spatial information
of snow cover images are complementary.

text: We explore the robustness and transferability of parameterizations of cloud
radiative forcing used in glacier melt models at two sites in the Swiss Alps.
We also look at the rationale behind some of the most commonly used approaches,
and explore the relationship between cloud transmittance and several standard
meteorological variables. The 2 m air-temperature diurnal range is the best predictor
of variations in cloud transmittance. However, linear and exponential parameterizations
can only explain 30–50% of the observed variance in computed cloud transmittance
factors. We examine the impact of modelled cloud transmittance factors on both
solar radiation and ablation rates computed with an enhanced temperature-index
model. The melt model performance decreases when modelled radiation is used, the
reduction being due to an underestimation of incoming solar radiation on clear-sky
days. The model works well under overcast conditions. We also seek alternatives
to the use of in situ ground data. However, outputs from an atmospheric model
(2.2 km horizontal resolution) do not seem to provide an alternative to the parameterizations
of cloud radiative forcing based on observations of air temperature at glacier
automatic weather stations. Conversely, the correct definition of overcast conditions
is important.

text: Streamflow is a hydrological variable measured at a defined river cross-section;
it spatially integrates the runoff generating processes in the contributing watershed,
including precipitation and air temperature. Trends in streamflow are progressive
changes in the time series of streamflow that can be detected with statistical
methods and their statistical significance can be assessed. Mountainous regions
are particularly vulnerable to streamflow change because of their high specific
runoff and the sensitivity to the distribution of precipitation and air temperature,
and the processes of snow accumulation and melt.

text: Recent experiments have shown that motion detection in Drosophila starts with
splitting the visual input into two parallel channels encoding brightness increments
(ON) or decrements (OFF). This suggests the existence of either two (ON-ON, OFF-OFF)
or four (for all pairwise interactions) separate motion detectors. To decide between
these possibilities, we stimulated flies using sequences of ON and OFF brightness
pulses while recording from motion-sensitive tangential cells. We found direction-selective
responses to sequences of same sign (ON-ON, OFF-OFF), but not of opposite sign
(ON-OFF, OFF-ON), refuting the existence of four separate detectors. Based on
further measurements, we propose a model that reproduces a variety of additional
experimental data sets, including ones that were previously interpreted as support
for four separate detectors. Our experiments and the derived model mark an important
step in guiding further dissection of the fly motion detection circuit.

text: We propose a general conjecture for the mixed Hodge polynomial of the generic
character varieties of representations of the fundamental group of a Riemann surface
of genus g to GLn(C) with fixed generic semisimple conjugacy classes at k punctures.
This conjecture generalizes the Cauchy identity for Macdonald polynomials and
is a common generalization of two formulas that we prove in this paper. The first
is a formula for the E-polynomial of these character varieties which we obtain
using the character table of GLn(Fq). We use this formula to compute the Euler
characteristic of character varieties. The second formula gives the Poincaré polynomial
of certain associated quiver varieties which we obtain using the character table
of gln(Fq). In the last main result we prove that the Poincaré polynomials of
the quiver varieties equal certain multiplicities in the tensor product of irreducible
characters of GLn(Fq). As a consequence we find a curious connection between Kac-Moody
algebras associated with comet-shaped, and typically wild, quivers and the representation
theory of GLn(Fq).

text: The emergence of differences in the arrangement of cells is the first step
towards the establishment of many organs. Understanding this process is limited
by the lack of systematic characterization of epithelial organisation. Here we
apply network theory at the scale of individual cells to uncover patterns in cell-to-cell
contacts that govern epithelial organisation. We provide an objective characterisation
of epithelia using network representation, where cells are nodes and cell contacts
are links. The features of individual cells, together with attributes of the cellular
network, produce a defining signature that distinguishes epithelia from different
organs, species, developmental stages and genetic conditions. The approach permits
characterization, quantification and classification of normal and perturbed epithelia,
and establishes a framework for understanding molecular mechanisms that underpin
the architecture of complex tissues.

text: Morphogens, such as Decapentaplegic (Dpp) in the fly imaginal discs, form
graded concentration profiles that control patterning and growth of developing
organs. In the imaginal discs, proliferative growth is homogeneous in space, posing
the conundrum of how morphogen concentration gradients could control position-independent
growth. To understand the mechanism of proliferation control by the Dpp gradient,
we quantified Dpp concentration and signaling levels during wing disc growth.
Both Dpp concentration and signaling gradients scale with tissue size during development.
On average, cells divide when Dpp signaling levels have increased by 50%. Our
observations are consistent with a growth control mechanism based on temporal
changes of cellular morphogen signaling levels. For a scaling gradient, this mechanism
generates position-independent growth rates.

text: Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal
leads is reported. The spin selectivity arises from an interplay of the orbital
effect of the magnetic field with the strong spin-orbit interaction present in
the valence band of the semiconductor. We demonstrate both experimentally and
theoretically that spin-selective tunneling in semiconductor nanostructures can
be achieved without the use of ferromagnetic contacts. The reported effect, which
relies on mixing the light and heavy holes, should be observable in a broad class
of quantum-dot systems formed in semiconductors with a degenerate valence band.

text: Superconducting circuits have been successfully established as systems to
prepare and investigate microwave light fields at the quantum level. In contrast
to optical experiments where light is detected using photon counters, microwaves
are usually measured with well developed linear amplifiers. This makes measurements
of correlation functions - one of the important tools in optics - harder to achieve
because they traditionally rely on photon counters and beam splitters. Here, we
demonstrate a system where we can prepare on demand single microwave photons in
a cavity and detect them at the two outputs of the cavity using linear amplifiers.
Together with efficient data processing, this allows us to measure different observables
of the cavity photons, including the first-order correlation function. Using these
techniques we demonstrate cooling of a thermal background field in the cavity.

text: A wide range of experiments studying microwave photons localized in superconducting
cavities have made important contributions to our understanding of the quantum
properties of radiation. Propagating microwave photons, however, have so far been
studied much less intensely. Here we present measurements in which we reconstruct
the quantum state of itinerant single photon Fock states and their superposition
with the vacuum by analyzing moments of the measured amplitude distribution up
to fourth order. Using linear amplifiers and quadrature amplitude detectors, we
have developed efficient methods to separate the detected single photon signal
from the noise added by the amplifier. From our measurement data we have also
reconstructed the corresponding Wigner function.

text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

text: At optical frequencies the radiation produced by a source, such as a laser,
a black body or a single-photon emitter, is frequently characterized by analysing
the temporal correlations of emitted photons using single-photon counters. At
microwave frequencies, however, there are no efficient single-photon counters
yet. Instead, well-developed linear amplifiers allow for efficient measurement
of the amplitude of an electromagnetic field. Here, we demonstrate first- and
second-order correlation function measurements of a pulsed microwave-frequency
single-photon source integrated on the same chip with a 50/50 beam splitter followed
by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon
coherence in first-order and photon antibunching in second-order correlation function
measurements of the propagating fields.

text: Microwave cavities with high quality factors enable coherent coupling of distant
quantum systems. Virtual photons lead to a transverse interaction between qubits
when they are nonresonant with the cavity but resonant with each other. We experimentally
investigate the inverse scaling of the interqubit coupling with the detuning from
a cavity mode and its proportionality to the qubit-cavity interaction strength.
We demonstrate that the enhanced coupling at higher frequencies is mediated by
multiple higher-harmonic cavity modes. Moreover, we observe dark states of the
coupled qubit-qubit system and analyze their relation to the symmetry of the applied
driving field at different frequencies.

text: Continuous variable entanglement between two modes of a radiation field is
usually studied at optical frequencies. Here we demonstrate experiments that show
the entanglement between microwave photons of different energy in a broadband
squeezed beam. We use a Josephson parametric amplifier to generate the two-mode
correlated state and detect all four quadrature components simultaneously in a
two-channel heterodyne setup using amplitude detectors. Analyzing two-dimensional
phase space histograms for all possible pairs of quadratures allows us to determine
the full covariance matrix, which is in good agreement with the one expected for
a two-mode squeezed state.

text: Many membrane channels and receptors exhibit adaptive, or desensitized, response
to a strong sustained input stimulus, often supported by protein activity-dependent
inactivation. Adaptive response is thought to be related to various cellular functions
such as homeostasis and enlargement of dynamic range by background compensation.
Here we study the quantitative relation between adaptive response and background
compensation within a modeling framework. We show that any particular type of
adaptive response is neither sufficient nor necessary for adaptive enlargement
of dynamic range. In particular a precise adaptive response, where system activity
is maintained at a constant level at steady state, does not ensure a large dynamic
range neither in input signal nor in system output. A general mechanism for input
dynamic range enlargement can come about from the activity-dependent modulation
of protein responsiveness by multiple biochemical modification, regardless of
the type of adaptive response it induces. Therefore hierarchical biochemical processes
such as methylation and phosphorylation are natural candidates to induce this
property in signaling systems.

text: The Levene model is the simplest mathematical model to describe the evolution
of gene frequencies in spatially subdivided populations. It provides insight into
how locally varying selection promotes a population’s genetic diversity. Despite
its simplicity, interesting problems have remained unsolved even in the diallelic
case. In this paper we answer an open problem by establishing that for two alleles
at one locus and J demes, up to 2J−1 polymorphic equilibria may coexist. We first
present a proof for the case of stable monomorphisms and then show that the result
also holds for protected alleles. These findings allow us to prove that any odd
number (up to 2J−1) of equilibria is possible, before we extend the proof to even
numbers. We conclude with some numerical results and show that for J>2, the
proportion of parameter space affording this maximum is extremely small.

text: 'Modern α-proteobacteria are thought to be closely related to the ancient
symbiont of eukaryotes, an ancestor of mitochondria. Respiratory complex I from
α-proteobacteria and mitochondria is well conserved at the level of the 14 "core"
subunits, consistent with that notion. Mitochondrial complex I contains the core
subunits, present in all species, and up to 31 "supernumerary" subunits,
generally thought to have originated only within eukaryotic lineages. However,
the full protein composition of an α-proteobacterial complex I has not been established
previously. Here, we report the first purification and characterization of complex
I from the α-proteobacterium Paracoccus denitrificans. Single particle electron
microscopy shows that the complex has a well defined L-shape. Unexpectedly, in
addition to the 14 core subunits, the enzyme also contains homologues of three
supernumerary mitochondrial subunits as follows: B17.2, AQDQ/18, and 13 kDa (bovine
nomenclature). This finding suggests that evolution of complex I via addition
of supernumerary or "accessory" subunits started before the original
endosymbiotic event that led to the creation of the eukaryotic cell. It also provides
further confirmation that α-proteobacteria are the closest extant relatives of
mitochondria.'

text: Complex I is the first and largest enzyme of the respiratory chain, coupling
electron transfer between NADH and ubiquinone to the translocation of four protons
across the membrane. It has a central role in cellular energy production and has
been implicated in many human neurodegenerative diseases. The L-shaped enzyme
consists of hydrophilic and membrane domains. Previously, we determined the structure
of the hydrophilic domain. Here we report the crystal structure of the Esherichia
coli complex I membrane domain at 3.0 Ã. resolution. It includes six subunits,
NuoL, NuoM, NuoN, NuoA, NuoJ and NuoK, with 55 transmembrane helices. The fold
of the homologous antiporter-like subunits L, M and N is novel, with two inverted
structural repeats of five transmembrane helices arranged, unusually, face-to-back.
Each repeat includes a discontinuous transmembrane helix and forms half of a channel
across the membrane. A network of conserved polar residues connects the two half-channels,
completing the proton translocation pathway. Unexpectedly, lysines rather than
carboxylate residues act as the main elements of the proton pump in these subunits.
The fourth probable proton-translocation channel is at the interface of subunits
N, K, J and A. The structure indicates that proton translocation in complex I,
uniquely, involves coordinated conformational changes in six symmetrical structural
elements.

text: Complex I is the first enzyme of the respiratory chain and plays a central
role in cellular energy production. It has been implicated in many human neurodegenerative
diseases, as well as in ageing. One of the biggest membrane protein complexes,
it is an L-shaped assembly consisting of hydrophilic and membrane domains. Previously,
we have determined structures of the hydrophilic domain in several redox states.
Last year was marked by fascinating breakthroughs in the understanding of the
complete structure. We described the architecture of the membrane domain and of
the entire bacterial complex I. X-ray analysis of the larger mitochondrial enzyme
has also been published. The core subunits of the bacterial and mitochondrial
enzymes have remarkably similar structures. The proposed mechanism of coupling
between electron transfer and proton translocation involves long-range conformational
changes, coordinated in part by a long α-helix, akin to the coupling rod of a
steam engine.

In Escherichia coli, the pole-to-pole oscillation of the Min proteins directs septum formation to midcell, which is required for symmetric cell division. In vitro, protein waves emerge from the self-organization of MinD, a membrane-binding ATPase, and its activator MinE. For wave propagation, the proteins need to cycle through states of collective membrane binding and unbinding. Although MinD presumably undergoes cooperative membrane attachment, it is unclear how synchronous detachment is coordinated. We used confocal and single-molecule microscopy to elucidate the order of events during Min wave propagation. We propose that protein detachment at the rear of the wave, and the formation of the E-ring, are accomplished by two complementary processes: first, local accumulation of MinE due to rapid rebinding, leading to dynamic instability; and second, a structural change induced by membrane-interaction of MinE in an equimolar MinD-MinE (MinDE) complex, which supports the robustness of pattern formation.

text: One of the most fundamental features of biological systems is probably their
ability to self-organize in space and time on different scales. Despite many elaborate
theoretical models of how molecular self-organization can come about, only a few
experimental systems of biological origin have so far been rigorously described,
due mostly to their inherent complexity. The most promising strategy of modern
biophysics is thus to identify minimal biological systems showing self-organized
emergent behavior. One of the best-understood examples of protein self-organization,
which has recently been successfully reconstituted in vitro, is represented by
the oscillations of the Min proteins in Escherichia coli. In this review, we summarize
the current understanding of the mechanism of Min protein self-organization in
vivo and in vitro. We discuss the potential of the Min oscillations to sense the
geometry of the cell and suggest that spontaneous protein waves could be a general
means of intracellular organization. We hypothesize that cooperative membrane
binding and unbinding, e.g., as an energy-dependent switch, may act as an important
regulatory mechanism for protein oscillations and pattern formation in the cell.

text: Many species have morphologically and genetically differentiated sex chromosomes,
such as the XY pair of mammals. Y chromosomes are often highly degenerated and
carry few functional genes, so that XY males have only one copy of most Xlinked
genes (whereas females have two). As a result, chromosome-wide mechanisms of dosage
compensation, such as the mammalian X-inactivation, often evolve to reestablish
expression balance. A similar phenomenon is expected in femaleheterogametic species,
where ZW females should suffer from imbalances due to W-chromosome degeneration.
However, no global dosage compensation mechanisms have been detected in the two
independent ZW systems that have been studied systematically (birds and silkworm),
leading to the suggestion that lack of global dosage compensation may be a general
feature of female-heterogametic species. However, analyses of other independently
evolved ZW systems are required to test if this is the case. In this study, we
use published genomic and expression data to test for the presence of global dosage
compensation in Schistosoma mansoni, a trematode parasite that causes schistosomiasis
in humans. We find that Z-linked expression is reduced relative to autosomal expression
in females but not males, consistent with incomplete or localized dosage compensation.
This gives further support to the theory that female-heterogametic species may
not require global mechanisms of dosage compensation.

text: We present a new technique for passive and markerless facial performance capture
based on anchor frames. Our method starts with high resolution per-frame geometry
acquisition using state-of-theart stereo reconstruction, and proceeds to establish
a single triangle mesh that is propagated through the entire performance. Leveraging
the fact that facial performances often contain repetitive subsequences, we identify
anchor frames as those which contain similar facial expressions to a manually
chosen reference expression. Anchor frames are automatically computed over one
or even multiple performances. We introduce a robust image-space tracking method
that computes pixel matches directly from the reference frame to all anchor frames,
and thereby to the remaining frames in the sequence via sequential matching. This
allows us to propagate one reconstructed frame to an entire sequence in parallel,
in contrast to previous sequential methods. Our anchored reconstruction approach
also limits tracker drift and robustly handles occlusions and motion blur. The
parallel tracking and mesh propagation offer low computation times. Our technique
will even automatically match anchor frames across different sequences captured
on different occasions, propagating a single mesh to all performances.

text: This chapter presents a method for real-time animation of highly detailed
facial expressions based on sparse motion captures data and a limited set of static
example poses. The method for real-time animation of highly detailed facial expressions
decomposes geometry into large-scale motion and fine-scale details, such as expression
wrinkles. Both large- and fine-scale deformation algorithms run entirely on the
GPU, and our implementation based on CUDA achieves an overall performance of about
30 fps. The face conveys the most relevant visual characteristics of human identity
and expression. Hence, realistic facial animations or interactions with virtual
avatars are important for storytelling and gameplay. However, current approaches
are either computationally expensive, require very specialized capture hardware,
or are extremely labor intensive. At runtime, given an arbitrary facial expression,
the algorithm computes the skin strain from the relative distance between marker
points and derives fine-scale corrections for the largescale deformation. During
gameplay only the sparse set of marker-point positions is transmitted to the GPU.
The face animation is entirely computed on the GPU where the resulting mesh can
directly be used as input for the rendering stages. This data can be easily obtained
by traditional capture hardware. The proposed in-game algorithm is fast. It also
is easy to implement and maps well onto programmable GPUs.

text: Let P be the Ornstein-Uhlenbeck semigroup associated with the stochastic Cauchy
problem dU(t)=AU(t)dt+dWH(t), where A is the generator of a C 0-semigroup S on
a Banach space E, H is a Hilbert subspace of E, and W H is an H-cylindrical Brownian
motion. Assuming that S restricts to a C 0-semigroup on H, we obtain L p -bounds
for D H P(t). We show that if P is analytic, then the invariance assumption is
fulfilled. As an application we determine the L p -domain of the generator of
P explicitly in the case where S restricts to a C 0-semigroup on H which is similar
to an analytic contraction semigroup. The results are applied to the 1D stochastic
heat equation driven by additive space-time white noise.

text: We study, in L1(R̃n; γ) with respect to the gaussian measure, non- tangential
maximal functions and conical square functions associ- ated with the Ornstein-Uhlenbeck
operator by developing a set of techniques which allow us, to some extent, to
compensate for the non-doubling character of the gaussian measure. The main result
asserts that conical square functions can be controlled in L1-norm by non-tangential
maximal functions. Along the way we prove a change of aperture result for the
latter. This complements recent results on gaussian Hardy spaces due to Mauceri
and Meda.

Let K be an irreducible and reversible Markov kernel on a finite set X. We construct a metric W on the set of probability measures on X and show that with respect to this metric, the law of the continuous time Markov chain evolves as the gradient flow of the entropy. This result is a discrete counterpart of the Wasserstein gradient flow interpretation of the heat flow in Rn by Jordan, Kinderlehrer and Otto (1998). The metric W is similar to, but different from, the L2-Wasserstein metric, and is defined via a discrete variant of the Benamou–Brenier formula.

text: A (diatomic) shape resonance is a metastable state of a pair of colliding
atoms quasi-bound by the centrifugal barrier imposed by the angular momentum involved
in the collision. The temporary trapping of the atoms' scattering wavefunction
corresponds to an enhanced atom pair density at low interatomic separations. This
leads to larger overlap of the wavefunctions involved in a molecule formation
process such as photoassociation, rendering the process more efficient. However,
for an ensemble of atoms, the atom pair density will only be enhanced if the energy
of the resonance comes close to the temperature of the atomic ensemble. Herein
we explore the possibility of controlling the energy of a shape resonance by shifting
it toward the temperature of atoms confined in a trap. The shifts are imparted
by the interaction of non-resonant light with the anisotropic polarizability of
the atom pair, which affects both the centrifugal barrier and the pair's rotational
and vibrational levels. We find that at laser intensities of up to 5×109 W/cm2
the pair density is increased by one order of magnitude for 87Rb atoms at 100μK
and by two orders of magnitude for 88Sr atoms at 20μK.

text: We made use of supersymmetric (SUSY) quantum mechanics to find the condition
under which the Stark effect problem for a polar and polarizable closed-shell
diatomic molecule subjected to collinear electrostatic and nonresonant radiative
fields becomes exactly solvable. The condition Δω = ω2/4(m+1)2 connects values
of the dimensionless parameters ω and Δω that characterize the strengths of the
permanent and induced dipole interactions of the molecule with the respective
fields. The exact solutions are obtained for the \J̃ = m, m; ω, Δω) family of
'stretched' states. The field-free and strong-field limits of the combined-fields
problem were found to exhibit supersymmetry and shape invariance, which is indeed
the reason why they are analytically solvable. By making use of the analytic form
of the \J̃ = m,m; ω, Δω) wavefunctions, we obtained simple formulae for the expectation
values of the space-fixed electric dipole moment, the alignment cosine and the
angular momentum squared, and derived a 'sum rule' that combines the above expectation
values into a formula for the eigenenergy. The analytic expressions for the characteristics
of the strongly oriented and aligned states provide direct access to the values
of the interaction parameters required for creating such states in the laboratory.

text: By invoking supersymmetry, we found a condition under which the Stark-effect
problem for a polar and polarizable molecule subject to nonresonant electric fields
becomes exactly solvable for the family of stretched states. The analytic expressions
for the wave function and eigenenergy and other expectation values allow one to
readily reverse-engineer the problem of finding the values of the interaction
parameters required for creating quantum states with preordained characteristics.
The method also allows the construction of families of isospectral potentials,
realizable with combined fields.

text: We show that dressing polar molecules with a far-off-resonant optical field
leads to new types of intermolecular potentials, which undergo a crossover from
the inverse power to oscillating behavior depending on the intermolecular distance,
and whose parameters can be tuned by varying the laser intensity and wavelength.
We present analytic expressions for the potential energy surfaces, thereby providing
direct access to the parameters of an optical field required to design intermolecular
interactions experimentally.

text: Soon, the genetic basis of most human Mendelian diseases will be solved. The
next challenge will be to leverage this information to uncover basic mechanisms
of disease and develop new therapies. To understand how this transformation is
already beginning to unfold, we focus on the ciliopathies, a class of multi-organ
diseases caused by disruption of the primary cilium. Through a convergence of
data involving mutant gene discovery, proteomics, and cell biology, more than
a dozen phenotypically distinguishable conditions are now united as ciliopathies.
Sitting at the interface between simple and complex genetic conditions, these
diseases provide clues to the future direction of human genetics.

text: The binding of polarons, or its absence, is an old and subtle topic. After
defining the model we state some recent theorems of ours. First, the transition
from many-body collapse to the existence of a thermodynamic limit for N polarons
occurs precisely at U = 2α, where U is the electronic Coulomb repulsion and α
is the polaron coupling constant. Second, if U is large enough, there is no multi-polaron
binding of any kind. We also discuss the Pekar-Tomasevich approximation to the
ground state energy, which is valid for large α. Finally, we derive exact results,
not reported before, about the one-dimensional toy model introduced by E. P. Gross.

text: 'We resolve several longstanding problems concerning the stability and the
absence of multi-particle binding for N≥2 polarons. Fröhlich''s 1937 polaron model
describes non-relativistic particles interacting with a scalar quantized field
with coupling √α, and with each other by Coulomb repulsion of strength U. We prove
the following: (i) While there is a known thermodynamic instability for U<2α,
stability of matter does hold for U>2α, that is, the ground state energy per
particle has a finite limit as N→∞. (ii) There is no binding of any kind if U
exceeds a critical value that depends on α but not on N. The same results are
shown to hold for the Pekar-Tomasevich model.'

text: The change in energy of an ideal Fermi gas when a local one-body potential
is inserted into the system, or when the density is changed locally, are important
quantities in condensed matter physics. We show that they can be rigorously bounded
from below by a universal constant times the value given by the semiclassical
approximation.

long range repulsive interactions. In particular, we prove that the Bogoliubov
spectrum of elementary excitations with linear dispersion relation for small momentum
becomes exact in the mean-field limit.

text: 'Let EMBEDk→d be the following algorithmic problem: Given a finite simplicial
complex K of dimension at most k, does there exist a (piecewise linear) embedding
of K into Rd? Known results easily imply the polynomiality of EMBEDk→2 (k = 1;
2; the case k = 1, d = 2 is graph planarity) and of EMBEDk→2k for all k ≥ 3. We
show that the celebrated result of Novikov on the algorithmic unsolvability of
recognizing the 5-sphere implies that EMBEDd→d and EMBED (d-1)→d are undecidable
for each d ≥ 5. Our main result is the NP-hardness of EMBED2→4 and, more generally,
of EMBED k→d for all k; d with d ≥ 4 and d ≥ k ≥ (2d - 2)/3. These dimensions
fall outside the metastable range of a theorem of Haefliger and Weber, which characterizes
embeddability using the deleted product obstruction. Our reductions are based
on examples, due to Segal, Spież, Freedman, Krushkal, Teichner, and Skopenkov,
showing that outside the metastable range the deleted product obstruction is not
sufficient to characterize embeddability. '

text: We introduce a new notion of minors for simplicial complexes (hypergraphs),
so-called homological minors. Our motivation is to propose a general approach
to attack certain extremal problems for sparse simplicial complexes and the corresponding
threshold problems for random complexes. In this paper, we focus on threshold
problems. The basic model for random complexes is the Linial-Meshulam model Xk(n,
p). By definition, such a complex has n vertices, a complete (k -1)-dimensional
skeleton, and every possible k-dimensional simplex is chosen independently with
probability p. We show that for every k, t≥ 1, there is a constant C = C(k, t)
such that for p≥ C/n, the random complex Xk(n, p) asymptotically almost surely
contains K tk (the complete k-dimensional complex on t vertices) as a homological
minor. As corollary, the threshold for (topological) embeddability of Xk(n, p)
into R2k is at p = θ(1/n). The method can be extended to other models of random
complexes (for which the lower skeleta are not necessarily complete) and also
to more general Tverberg-type problems, where instead of continuous maps without
doubly covered image points (embeddings), we consider maps without qfold covered
image points.

text: Within a multicellular tissue cells may coordinately form a singular or multiple
polar axes, but it is unclear whether a common mechanism governs different types
of polar axis formation. The phosphorylation status of PIN proteins, which is
directly affected by the PINOID (PID) protein kinase and the PP2A protein phosphatase,
is known to regulate the apical-basal polarity of PIN localization in bipolar
cells of roots and shoot apices. Here, we provide evidence that the phosphorylation
status-mediated PIN polarity switch is widely used to modulate cellular processes
in Arabidopsis including multipolar pavement cells (PC) with interdigitated lobes
and indentations. The degree of PC interdigitation was greatly reduced either
when the FYPP1 gene, which encodes a PP2A called phytochrome-associated serine/threonine
protein phosphatase, was knocked out or when the PID gene was overexpressed (35S:PID).
These genetic modifications caused PIN1 localization to switch from lobe to indentation
regions. The PP2A and PID mediated switching of PIN1 localization is strikingly
similar to their regulation of the apical-basal polarity switch of PIN proteins
in other cells. Our findings suggest a common mechanism for the regulation of
PIN1 polarity formation, a fundamental cellular process that is crucial for pattern
formation both at the tissue/organ and cellular levels.
