text: 'Relational models for contingency tables are generalizations of log-linear
models, allowing effects associated with arbitrary subsets of cells in the table,
and not necessarily containing the overall effect, that is, a common parameter
in every cell. Similarly to log-linear models, relational models can be extended
to non-negative distributions, but the extension requires more complex methods.
An extended relational model is defined as an algebraic variety, and it turns
out to be the closure of the original model with respect to the Bregman divergence.
In the extended relational model, the MLE of the cell parameters always exists
and is unique, but some of its properties may be different from those of the MLE
under log-linear models. The MLE can be computed using a generalized iterative
scaling procedure based on Bregman projections. '

text: 'We consider random matrices of the form H=W+λV, λ∈ℝ+, where W is a real symmetric
or complex Hermitian Wigner matrix of size N and V is a real bounded diagonal
random matrix of size N with i.i.d.\ entries that are independent of W. We assume
subexponential decay for the matrix entries of W and we choose λ∼1, so that the
eigenvalues of W and λV are typically of the same order. Further, we assume that
the density of the entries of V is supported on a single interval and is convex
near the edges of its support. In this paper we prove that there is λ+∈ℝ+ such
that the largest eigenvalues of H are in the limit of large N determined by the
order statistics of V for λ>λ+. In particular, the largest eigenvalue of H
has a Weibull distribution in the limit N→∞ if λ>λ+. Moreover, for N sufficiently
large, we show that the eigenvectors associated to the largest eigenvalues are
partially localized for λ>λ+, while they are completely delocalized for λ<λ+.
Similar results hold for the lowest eigenvalues. '

text: Consider the transmission of a polar code of block length N and rate R over
a binary memoryless symmetric channel W and let P e be the block error probability
under successive cancellation decoding. In this paper, we develop new bounds that
characterize the relationship of the parameters R, N, P e , and the quality of
the channel W quantified by its capacity I(W) and its Bhattacharyya parameter
Z(W). In previous work, two main regimes were studied. In the error exponent regime,
the channel W and the rate R <; I(W) are fixed, and it was proved that the error
probability Pe scales roughly as 2 -√N . In the scaling exponent approach, the
channel W and the error probability Pe are fixed and it was proved that the gap
to capacity I(W) - R scales as N -1/μ . Here, μ is called scaling exponent and
this scaling exponent depends on the channel W. A heuristic computation for the
binary erasure channel (BEC) gives μ = 3.627 and it was shown that, for any channel
W, 3.579 ≤ μ ≤ 5.702. Our contributions are as follows. First, we provide the
tighter upper bound μ <;≤ 4.714 valid for any W. With the same technique, we obtain
the upper bound μ ≤ 3.639 for the case of the BEC; this upper bound approaches
very closely the heuristically derived value for the scaling exponent of the erasure
channel. Second, we develop a trade-off between the gap to capacity I(W)- R and
the error probability Pe as the functions of the block length N. In other words,
we neither fix the gap to capacity (error exponent regime) nor the error probability
(scaling exponent regime), but we do consider a moderate deviations regime in
which we study how fast both quantities, as the functions of the block length
N, simultaneously go to 0. Third, we prove that polar codes are not affected by
error floors. To do so, we fix a polar code of block length N and rate R. Then,
we vary the channel W and study the impact of this variation on the error probability.
We show that the error probability Pe scales as the Bhattacharyya parameter Z(W)
raised to a power that scales roughly like VN. This agrees with the scaling in
the error exponent regime.

text: 'The question whether RM codes are capacity-achieving is a long-standing open
problem in coding theory that was recently answered in the affirmative for transmission
over erasure channels [1], [2]. Remarkably, the proof does not rely on specific
properties of RM codes, apart from their symmetry. Indeed, the main technical
result consists in showing that any sequence of linear codes, with doubly-transitive
permutation groups, achieves capacity on the memoryless erasure channel under
bit-MAP decoding. Thus, a natural question is what happens under block-MAP decoding.
In [1], [2], by exploiting further symmetries of the code, the bit-MAP threshold
was shown to be sharp enough so that the block erasure probability also converges
to 0. However, this technique relies heavily on the fact that the transmission
is over an erasure channel. We present an alternative approach to strengthen results
regarding the bit-MAP threshold to block-MAP thresholds. This approach is based
on a careful analysis of the weight distribution of RM codes. In particular, the
flavor of the main result is the following: assume that the bit-MAP error probability
decays as N -δ , for some δ > 0. Then, the block-MAP error probability also converges
to 0. This technique applies to transmission over any binary memoryless symmetric
channel. Thus, it can be thought of as a first step in extending the proof that
RM codes are capacity-achieving to the general case.'

technical result consists in showing that any sequence of linear codes, with doubly-transitive
permutation groups, achieves capacity on the memoryless erasure channel under
bit-MAP decoding. A natural question is what happens under block-MAP decoding.
If the minimum distance of the code family is close to linear (e.g., of order
N/ log(N)), then one can combine an upper bound on the bit-MAP error probability
with a lower bound on the minimum distance to show that the code family is also
capacity-achieving under block-MAP decoding. This strategy is successful for BCH
codes. Unfortunately, the minimum distance of RM codes scales only as √N, which
does not suffice to obtain the desired result. Then, one can exploit further symmetries
of RM codes to show that the bit-MAP threshold is sharp enough so that the block

text: Electrons in materials with linear dispersion behave as massless Weyl- or
Dirac-quasiparticles, and continue to intrigue due to their close resemblance
to elusive ultra-relativistic particles as well as their potential for future
electronics. Yet the experimental signatures of Weyl-fermions are often subtle
and indirect, in particular if they coexist with conventional, massive quasiparticles.
Here we show a pronounced anomaly in the magnetic torque of the Weyl semimetal
NbAs upon entering the quantum limit state in high magnetic fields. The torque
changes sign in the quantum limit, signalling a reversal of the magnetic anisotropy
that can be directly attributed to the topological nature of the Weyl electrons.
Our results establish that anomalous quantum limit torque measurements provide
a direct experimental method to identify and distinguish Weyl and Dirac systems.

text: The observation of a reconstructed Fermi surface via quantum oscillations
in hole-doped cuprates opened a path towards identifying broken symmetry states
in the pseudogap regime. However, such an identification has remained inconclusive
due to the multi-frequency quantum oscillation spectra and complications accounting
for bilayer effects in most studies. We overcome these impediments with high-resolution
measurements on the structurally simpler cuprate HgBa2CuO4+δ (Hg1201), which features
one CuO2 plane per primitive unit cell. We find only a single oscillatory component
with no signatures of magnetic breakdown tunnelling to additional orbits. Therefore,
the Fermi surface comprises a single quasi-two-dimensional pocket. Quantitative
modelling of these results indicates that a biaxial charge density wave within
each CuO2 plane is responsible for the reconstruction and rules out criss-crossed
charge stripes between layers as a viable alternative in Hg1201. Lastly, we determine
that the characteristic gap between reconstructed pockets is a significant fraction
of the pseudogap energy.

text: Kinetics of electrochemical reactions are several orders of magnitude slower
in solids than in liquids as a result of the much lower ion diffusivity. Yet,
the solid state maximizes the density of redox species, which is at least two
orders of magnitude lower in liquids because of solubility limitations. With regard
to electrochemical energy storage devices, this leads to high-energy batteries
with limited power and high-power supercapacitors with a well-known energy deficiency.
For such devices the ideal system should endow the liquid state with a density
of redox species close to the solid state. Here we report an approach based on
biredox ionic liquids to achieve bulk-like redox density at liquid-like fast kinetics.
The cation and anion of these biredox ionic liquids bear moieties that undergo
very fast reversible redox reactions. As a first demonstration of their potential
for high-capacity/high-rate charge storage, we used them in redox supercapacitors.
These ionic liquids are able to decouple charge storage from an ion-accessible
electrode surface, by storing significant charge in the pores of the electrodes,
to minimize self-discharge and leakage current as a result of retaining the redox
species in the pores, and to raise working voltage due to their wide electrochemical
window.

text: If proton exchange membrane fuel cells (PEMFC) are ever to succeed in sustainable
energy landscape as a potential zero emission technology, it is inevitable to
reduce electricity production cost associated mainly with its MEAs, cell hardware
and gas storage units. We demonstrate a diverse strategy for achieving this target
with a concomitant amplification of its specific energy and power, by rolling
a thin graphene oxide (GO) based MEA alone into a tubular and air breathing architecture
with internal fuel storage. The unique properties of GO being a barrier for molecular
fuels and proton conducting to construct a GO based cylindrical MEA. This makes
the tubular PEMFC ∼75 times lighter, featuring ∼37 and ∼92 times respectively,
the power and energy per overall weight, making it a potential candidate for portable
applications. The intrinsic electrochemical kinetics at the three-phase boundary
are somewhat affected by the bending of the MEA, albeit at overall reduction in
power production cost.

text: Mesoporous nanocrystalline TiO2 and TiO2–V2O5 microspheres were prepared by
non-hydrolytic sol–gel from TiCl4, VOCl3, and iPr2O at 110 °C without any solvent
or additives. The samples were characterized by elemental analysis, X-ray diffraction,
Raman spectroscopy, scanning electron microscopy, nitrogen physisorption, and
impedance measurements. At low vanadium loadings, only TiO2 anatase was detected,
and V2O5 scherbinaite was also detected at high vanadium loadings. The texture
of the samples depended on the V loading, but all the samples appeared built of
primary nanoparticles (≈10–20 nm in size) that aggregate to form mesoporous micron-sized
spheres. The lithium insertion properties of these materials were evaluated by
galvanostatic measurements taken using coin-type cells, in view of their application
as electrode for rechargeable Li-ion batteries. The mesoporous TiO2 microspheres
showed good performances, with a specific reversible capacity of 145 and 128 mAh
g−1 at C/2 and C, respectively (C = 335.6 mA g−1), good coulombic efficiency,
and a moderate capacity fade (6 %) from the 2nd to the 20th cycle at C/20. Although
the addition of V effectively increased the electronic conductivity of the powders,
the specific reversible capacity and cycling performances of the TiO2–V2O5 samples
were only minimally improved for a 5 at% V loading and were lower at higher V
loading.

text: Redox ionic liquids consisting of ions bearing redox moieties are receiving
increasing interest in electrochemical applications, as they associate electroactive
properties with the classical properties of ionic liquids. Here, biredox ionic
liquid electrolytes are described in which both anion and cation are functionalized
with anthraquinone and 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) groups, respectively.
In-depth investigations based on crossed experimental and theoretical studies
were carried out to elucidate how the bulkiness of ions bearing a redox moiety
impacted electron and mass transfers, and accordingly the efficiency of electrochemical
devices. The values of solvated radii of different redox ions, as well as the
related kinetic constants, were extracted from cyclic voltammetry experiments.
Reformulating the basic relations of electron transfer theory (based on Marcus-Hush
theory) evidenced that in such redox species, with an unsymmetrical located redox
centre, the electron transfer was not governed by the overall size of the solvated
redox species, but rather by the radius of the redox active subunit, which takes
preferential orientation towards the surface, thus allowing higher kinetic constants
than what classical theory would predict. This vision opens ample opportunities
for biredox ILs as electrolytes in electrochemical devices.

text: Within the scope of developing a multi-physical model describing battery behavior
during and after the mechanical load (accelerations, intrusions) of a vehicle’s
high voltage battery, an internal short circuit model is of deep interest for
a virtual hazard assessment. The internal short resistance and the size of the
affected area must be known as a minimum for determining the released heat and,
in consequence, the temperatures. The internal short resistance of purpose-built
dummy pouch cells, filled with electrolyte-like solvent without conductive salt,
has thus been measured in a given short area under various compressive loads.
The resistances for different short scenarios obtained are analyzed and described
in a mathematical form. Short circuit experiments with dummy cells using an external
power source have also been carried out. This set-up allows the measurement of
the temperature evolution at a known current and a determination of the actual
short resistance. The post-mortem analysis of the samples shows a correlation
between the maximum temperatures, released short heat and the separator melt diameter.

text: Lithium-ion batteries are in widespread use in electric vehicles and hybrid
vehicles. Besides features like energy density, cost, lifetime, and recyclability
the safety of a battery system is of prime importance. The separator material
impacts all these properties and requires therefore an informed selection. The
interplay between the mechanical and electrochemical properties as key selection
criteria is investigated. Mechanical properties were investigated using tensile
and puncture penetration tests at abuse relevant conditions. To investigate the
electrochemical performance in terms of effective conductivity a method based
on impedance spectroscopy was introduced. This methodology is applied to evaluate
ten commercial separators which allows for a trade-off analysis of mechanical
versus electrochemical performance. Based on the results, and in combination with
other factors, this offers an effective approach to select suitable separators
for automotive applications.

text: Normal leaf margin development is important for leaf morphogenesis and contributes
to diverse leaf shapes in higher plants. We here show the crucial roles of an
atypical type II phosphatidylinositol 4-kinase, PI4Kγ5, in Arabidopsis leaf margin
development. PI4Kγ5 presents a dynamics expression pattern along with leaf development
and a T-DNA mutant lacking PI4Kγ5, pi4kγ5–1, presents serrated leaves, which is
resulted from the accelerated cell division and increased auxin concentration
at serration tips. Studies revealed that PI4Kγ5 interacts with and phosphorylates
a membrane-bound NAC transcription factor, ANAC078. Previous studies demonstrated
that membrane-bound transcription factors regulate gene transcription by undergoing
proteolytic process to translocate into nucleus, and ANAC078 undergoes proteolysis
by cleaving off the transmembrane region and carboxyl terminal. Western blot analysis
indeed showed that ANAC078 deleting of carboxyl terminal is significantly reduced
in pi4kγ5–1, indicating that PI4Kγ5 is important for the cleavage of ANAC078.
This is consistent with the subcellular localization observation showing that
fluorescence by GFP-ANAC078 is detected at plasma membrane but not nucleus in
pi4kγ5–1 mutant and that expression of ANAC078 deleting of carboxyl terminal,
driven by PI4Kγ5 promoter, could rescue the leaf serration defects of pi4kγ5–1.
Further analysis showed that ANAC078 suppresses the auxin synthesis by directly
binding and regulating the expression of auxin synthesis-related genes. These
results indicate that PI4Kγ5 interacts with ANAC078 to negatively regulate auxin
synthesis and hence influences cell proliferation and leaf development, providing
informative clues for the regulation of in situ auxin synthesis and cell division,
as well as the cleavage and functional mechanism of membrane-bound transcription
factors.

text: "Importance: Considerable partner resemblances have been found for a wide
range of psychiatric disorders, meaning that partners of affected individuals
have an increased risk of being affected compared with partners of unaffected
individuals. If this resemblance is reflected in genetic similarity between partners,
genetic risk is anticipated to accumulate in offspring, but these potential consequences
have not been quantified and have been left implicit.\r\n\r\nObservations: The
anticipated consequences of partner resemblance on prevalence and heritability
of psychiatric traits in the offspring generation were modeled for disorders with
varying heritabilities, population prevalence (lifetime risk), and magnitudes
of partner resemblance. These models facilitate interpretation for a wide range
of psychiatric disorders, such as autism, schizophrenia, and depression. The genetic
consequences of partner resemblance are most pronounced when attributable to phenotypic
assortment (driven by the psychiatric trait). Phenotypic assortment results in
increased genetic variance in the offspring generation, which may result in increased
heritability and population prevalence. These consequences add generation after
generation to a limit, but assortative mating is unlikely to balance the impact
of reduced fecundity of patients with psychiatric disorders in the long term.
This modeling suggests that the heritabilities of psychiatric disorders are unlikely
to increase by more than 5% from 1 generation of assortative mating (maximally
13% across multiple generations). The population prevalence will increase most
for less common disorders with high heritability; for example, the prevalence
of autism might increase by 1.5-fold after 1 generation of assortative mating
(≥2.4-fold in the long term) depending on several assumptions.\r\n\r\nConclusions
and Relevance: The considerable partner resemblances found for psychiatric disorders
deserve more detailed interpretation than has been provided thus far. Although
the limitations of modeling are emphasized, the anticipated consequences are at
most modest for the heritability but may be considerable for the population prevalence
of rare disorders with a high heritability."

text: We develop a novel approach to identify regions of the genome underlying population
genetic differentiation in any genetic data where the underlying population structure
is unknown, or where the interest is assessing divergence along a gradient. By
combining the statistical framework for genome-wide association studies (GWASs)
with eigenvector decomposition (EigenGWAS), which is commonly used in population
genetics to characterize the structure of genetic data, loci under selection can
be identified without a requirement for discrete populations. We show through
theory and simulation that our approach can identify regions under selection along
gradients of ancestry, and in real data we confirm this by demonstrating LCT to
be under selection between HapMap CEU–TSI cohorts, and we then validate this selection
signal across European countries in the POPRES samples. HERC2 was also found to
be differentiated between both the CEU–TSI cohort and within the POPRES sample,
reflecting the likely anthropological differences in skin and hair colour between
northern and southern European populations. Controlling for population stratification
is of great importance in any quantitative genetic study and our approach also
provides a simple, fast and accurate way of predicting principal components in
independent samples. With ever increasing sample sizes across many fields, this
approach is likely to be greatly utilized to gain individual-level eigenvectors
avoiding the computational challenges associated with conducting singular value
decomposition in large data sets. We have developed freely available software,
Genetic Analysis Repository (GEAR), to facilitate the application of the methods.

text: Genome-wide association studies (GWAS) have identified thousands of genetic
variants associated with human complex traits. However, the genes or functional
DNA elements through which these variants exert their effects on the traits are
often unknown. We propose a method (called SMR) that integrates summary-level
data from GWAS with data from expression quantitative trait locus (eQTL) studies
to identify genes whose expression levels are associated with a complex trait
because of pleiotropy. We apply the method to five human complex traits using
GWAS data on up to 339,224 individuals and eQTL data on 5,311 individuals, and
we prioritize 126 genes (for example, TRAF1 and ANKRD55 for rheumatoid arthritis
and SNX19 and NMRAL1 for schizophrenia), of which 25 genes are new candidates;
77 genes are not the nearest annotated gene to the top associated GWAS SNP. These
genes provide important leads to design future functional studies to understand
the mechanism whereby DNA variation leads to complex trait variation.

text: We propose a Widom-like scaling ansatz for the critical jamming transition.
Our ansatz for the elastic energy shows that the scaling of the energy, compressive
strain, shear strain, system size, pressure, shear stress, bulk modulus, and shear
modulus are all related to each other via scaling relations, with only three independent
scaling exponents. We extract the values of these exponents from already known
numerical or theoretical results, and we numerically verify the resulting predictions
of the scaling theory for the energy and residual shear stress. We also derive
a scaling relation between pressure and residual shear stress that yields insight
into why the shear and bulk moduli scale differently. Our theory shows that the
jamming transition exhibits an emergent scale invariance, setting the stage for
the potential development of a renormalization group theory for jamming.
