text: Much of quantitative genetics is based on the ‘infinitesimal model’, under
which selection has a negligible effect on the genetic variance. This is typically
justified by assuming a very large number of loci with additive effects. However,
it applies even when genes interact, provided that the number of loci is large
enough that selection on each of them is weak relative to random drift. In the
long term, directional selection will change allele frequencies, but even then,
the effects of epistasis on the ultimate change in trait mean due to selection
may be modest. Stabilising selection can maintain many traits close to their optima,
even when the underlying alleles are weakly selected. However, the number of traits
that can be optimised is apparently limited to ~4Ne by the ‘drift load’, and this
is hard to reconcile with the apparent complexity of many organisms. Just as for
the mutation load, this limit can be evaded by a particular form of negative epistasis.
A more robust limit is set by the variance in reproductive success. This suggests
that selection accumulates information most efficiently in the infinitesimal regime,
when selection on individual alleles is weak, and comparable with random drift.
A review of evidence on selection strength suggests that although most variance
in fitness may be because of alleles with large Nes, substantial amounts of adaptation
may be because of alleles in the infinitesimal regime, in which epistasis has
modest effects.

text: 'Summary: Declining populations of bee pollinators are a cause of concern,
with major repercussions for biodiversity loss and food security. RNA viruses
associated with honeybees represent a potential threat to other insect pollinators,
but the extent of this threat is poorly understood. This study aims to attain
a detailed understanding of the current and ongoing risk of emerging infectious
disease (EID) transmission between managed and wild pollinator species across
a wide range of RNA viruses. Within a structured large-scale national survey across
26 independent sites, we quantify the prevalence and pathogen loads of multiple
RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee
(Bombus spp.) populations. We then construct models that compare virus prevalence
between wild and managed pollinators. Multiple RNA viruses associated with honeybees
are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees
is a significant predictor of virus prevalence in bumblebees, but we remain cautious
in speculating over the principle direction of pathogen transmission. We demonstrate
species-specific differences in prevalence, indicating significant variation in
disease susceptibility or tolerance. Pathogen loads within individual bumblebees
may be high and in the case of at least one RNA virus, prevalence is higher in
wild bumblebees than in managed honeybee populations. Our findings indicate widespread
transmission of RNA viruses between managed and wild bee pollinators, pointing
to an interconnected network of potential disease pressures within and among pollinator
species. In the context of the biodiversity crisis, our study emphasizes the importance
of targeting a wide range of pathogens and defining host associations when considering
potential drivers of population decline.'

text: The half-filled Landau level is expected to be approximately particle-hole
symmetric, which requires an extension of the Halperin-Lee-Read (HLR) theory of
the compressible state observed at this filling. Recent work indicates that, when
particle-hole symmetry is preserved, the composite fermions experience a quantized
π-Berry phase upon winding around the composite Fermi surface, analogous to Dirac
fermions at the surface of a 3D topological insulator. In contrast, the effective
low-energy theory of the composite fermion liquid originally proposed by HLR lacks
particle-hole symmetry and has vanishing Berry phase. In this paper, we explain
how thermoelectric transport measurements can be used to test the Dirac nature
of the composite fermions by quantitatively extracting this Berry phase. First,
we point out that longitudinal thermopower (Seebeck effect) is nonvanishing because
of the unusual nature of particle-hole symmetry in this context and is not sensitive
to the Berry phase. In contrast, we find that off-diagonal thermopower (Nernst
effect) is directly related to the topological structure of the composite Fermi
surface, vanishing for zero Berry phase and taking its maximal value for π Berry
phase. In contrast, in purely electrical transport signatures, the Berry phase
contributions appear as small corrections to a large background signal, making
the Nernst effect a promising diagnostic of the Dirac nature of composite fermions.

text: The entanglement spectrum of the reduced density matrix contains information
beyond the von Neumann entropy and provides unique insights into exotic orders
or critical behavior of quantum systems. Here, we show that strongly disordered
systems in the many-body localized phase have power-law entanglement spectra,
arising from the presence of extensively many local integrals of motion. The power-law
entanglement spectrum distinguishes many-body localized systems from ergodic systems,
as well as from ground states of gapped integrable models or free systems in the
vicinity of scale-invariant critical points. We confirm our results using large-scale
exact diagonalization. In addition, we develop a matrix-product state algorithm
which allows us to access the eigenstates of large systems close to the localization
transition, and discuss general implications of our results for variational studies
of highly excited eigenstates in many-body localized systems.

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.'

text: "We describe a new method to compare the bit-MAP and block-MAP decoding thresholds
of Reed-Muller (RM) codes for transmission over a binary memoryless symmetric
channel. The question whether RM codes are capacity-achieving is a long-standing
open problem in coding theory and it has recently been answered in the affirmative
for transmission over\r\nerasure channels. 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. 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
erasure probability also tends to 0. However, this technique relies heavily on
the fact that the transmission is over an erasure channel.\r\nWe 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\r\nerror
probability also converges to 0. This technique applies to the 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."

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: We report on magnetotransport studies of dual-gated, Bernal-stacked trilayer
graphene (TLG) encapsulated in boron nitride crystals. We observe a quantum Hall
effect staircase which indicates a complete lifting of the 12-fold degeneracy
of the zeroth Landau level. As a function of perpendicular electric field, our
data exhibit a sequence of phase transitions between all integer quantum Hall
states in the filling factor interval -8<ν<0. We develop a theoretical model
and argue that, in contrast to monolayer and bilayer graphene, the observed Landau
level splittings and quantum Hall phase transitions can be understood within a
single-particle picture, but imply the presence of a charge density imbalance
between the inner and outer layers of TLG, even at charge neutrality and zero
transverse electric field. Our results indicate the importance of a previously
unaccounted band structure parameter which, together with a more accurate estimate
of the other tight-binding parameters, results in a significantly improved determination
of the electronic and Landau level structure of TLG.

text: The many-body localization transition (MBLT) between ergodic and many-body
localized phases in disordered interacting systems is a subject of much recent
interest. The statistics of eigenenergies is known to be a powerful probe of crossovers
between ergodic and integrable systems in simpler examples of quantum chaos. We
consider the evolution of the spectral statistics across the MBLT, starting with
mapping to a Brownian motion process that analytically relates the spectral properties
to the statistics of matrix elements. We demonstrate that the flow from Wigner-Dyson
to Poisson statistics is a two-stage process. First, a fractal enhancement of
matrix elements upon approaching the MBLT from the delocalized side produces an
effective power-law interaction between energy levels, and leads to a plasma model
for level statistics. At the second stage, the gas of eigenvalues has local interactions
and the level statistics belongs to a semi-Poisson universality class. We verify
our findings numerically on the XXZ spin chain. We provide a microscopic understanding
of the level statistics across the MBLT and discuss implications for the transition
that are strong constraints on possible theories.
