text: In the Minimum Description Length (MDL) principle, learning from the data
is equivalent to an optimal coding problem. We show that the codes that achieve
optimal compression in MDL are critical in a very precise sense. First, when they
are taken as generative models of samples, they generate samples with broad empirical
distributions and with a high value of the relevance, defined as the entropy of
the empirical frequencies. These results are derived for different statistical
models (Dirichlet model, independent and pairwise dependent spin models, and restricted
Boltzmann machines). Second, MDL codes sit precisely at a second order phase transition
point where the symmetry between the sampled outcomes is spontaneously broken.
The order parameter controlling the phase transition is the coding cost of the
samples. The phase transition is a manifestation of the optimality of MDL codes,
and it arises because codes that achieve a higher compression do not exist. These
results suggest a clear interpretation of the widespread occurrence of statistical
criticality as a characterization of samples which are maximally informative on
the underlying generative process.

text: Escaping local optima is one of the major obstacles to function optimisation.
Using the metaphor of a fitness landscape, local optima correspond to hills separated
by fitness valleys that have to be overcome. We define a class of fitness valleys
of tunable difficulty by considering their length, representing the Hamming path
between the two optima and their depth, the drop in fitness. For this function
class we present a runtime comparison between stochastic search algorithms using
different search strategies. The (1+1) EA is a simple and well-studied evolutionary
algorithm that has to jump across the valley to a point of higher fitness because
it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm
and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population
genetics, are both able to cross the fitness valley by accepting worsening moves.
We show that the runtime of the (1+1) EA depends critically on the length of the
valley while the runtimes of the non-elitist algorithms depend crucially on the
depth of the valley. Moreover, we show that both SSWM and Metropolis can also
efficiently optimise a rugged function consisting of consecutive valleys.

text: The recent demand of multifunctional materials and devices for advanced applications
in energy conversion and data storage resulted into a revival of multiferroics,
that is, materials characterized by the coexistence of ferromagnetism and ferroelectricity.
Despite intense efforts made in the past decade, single-phase room temperature
multiferroics are yet to be discovered/fabricated. Nanostructured ferroic materials
could potentially exhibit multiferroism since a high fraction of their atoms/ions
are superficial, thereby altering significantly the properties of the bulk phase.
Alternately, a magnetic order can be induced into ferroelectric materials upon
aliovalent doping with magnetic ions. Here, we report on the synthesis of aggregate-free
single-phase transition-metal-doped BaTiO3 quasi-monodisperse cuboidal nanocrystals
(NC) which exhibit multiferroic properties at room temperature and can be suitable
for applications in data storage. The proposed synthetic route allows the inclusion
of a high concentration of magnetic ions such as Mn+ (M = Cr, Mn, Fe, Co) up to
a nominal concentration of 4% without the formation of any secondary phase. The
size of the nanocrystals was controlled in a wide range from ∼15 up to ∼70 nm
by varying the reaction time from 48 to 144 h. The presence of unpaired electrons
and their magnetic ordering have been probed by electron paramagnetic resonance
spectroscopy (EPR), and a vibrating sample magnetometer (VSM). Likewise, an acentric
structure, associated with the existence of a dielectric polarization, was observed
by lattice dynamics analysis and piezoresponse force microscopy (PFM). These results
show that high-quality titanium-containing perovskite nanocrystals which display
multiferroic properties at room temperature can be fabricated via soft solution-based
synthetic routes, and the properties of these materials can be modulated by changing
the size of the nanocrystals and the concentration of the dopant thereby opening
the door to the design and study of single-phase multiferroic materials.

text: 'Solid alkali metal carbonates are universal passivation layer components
of intercalation battery materials and common side products in metal‐O2 batteries,
and are believed to form and decompose reversibly in metal‐O2/CO2 cells. In these
cathodes, Li2CO3 decomposes to CO2 when exposed to potentials above 3.8 V vs.
Li/Li+. However, O2 evolution, as would be expected according to the decomposition
reaction 2 Li2CO3→4 Li++4 e−+2 CO2+O2, is not detected. O atoms are thus unaccounted
for, which was previously ascribed to unidentified parasitic reactions. Here,
we show that highly reactive singlet oxygen (1O2) forms upon oxidizing Li2CO3
in an aprotic electrolyte and therefore does not evolve as O2. These results have
substantial implications for the long‐term cyclability of batteries: they underpin
the importance of avoiding 1O2 in metal‐O2 batteries, question the possibility
of a reversible metal‐O2/CO2 battery based on a carbonate discharge product, and
help explain the interfacial reactivity of transition‐metal cathodes with residual
Li2CO3.'

text: Hydrogelation, the self-assembly of molecules into soft, water-loaded networks,
is one way to bridge the structural gap between single molecules and functional
materials. The potential of hydrogels, such as those based on perylene bisimides,
lies in their chemical, physical, optical, and electronic properties, which are
governed by the supramolecular structure of the gel. However, the structural motifs
and their precise role for long-range conductivity are yet to be explored. Here,
we present a comprehensive structural picture of a perylene bisimide hydrogel,
suggesting that its long-range conductivity is limited by charge transfer between
electronic backbones. We reveal nanocrystalline ribbon-like structures as the
electronic and structural backbone units between which charge transfer is mediated
by polar solvent bridges. We exemplify this effect with sensing, where exposure
to polar vapor enhances conductivity by 5 orders of magnitude, emphasizing the
crucial role of the interplay between structural motif and surrounding medium
for the rational design of devices based on nanocrystalline hydrogels.

text: The solid electrolyte interphase (SEI) in Li and Na ion batteries forms when
highly reducing or oxidizing electrode materials come into contact with a liquid
organic electrolyte. Its ability to form a mechanically robust, ion-conducting,
and electron-insulating layer critically determines performance, cycle life, and
safety. Li or Na alkyl carbonates (LiAC and NaAC, respectively) are lead SEI components
in state-of-the-art carbonate based electrolytes, and our fundamental understanding
of their charge transport and mechanical properties may hold the key to designing
electrolytes forming an improved SEI. We synthesized a homologous series of LiACs
and NaACs from methyl to octyl analogues and characterized them with respect to
structure, ionic conductivity, and stiffness. The compounds assume layered structures
except for the lithium methyl carbonate. Room-temperature conductivities were
found to be ∼10–9 S cm–1 for lithium methyl carbonate, <10–12 S cm–1 for the other
LiACs, and <10–12 S cm–1 for the NaACs with ion transport mostly attributed to
grain boundaries. While LiACs show stiffnesses of ∼1 GPa, NaACs become significantly
softer with increasing chain lengths. These findings will help to more precisely
interpret the complex results from charge transport and mechanical characterization
of real SEIs and can give a rationale for influencing the SEI’s mechanical properties
via the electrolyte.

text: Passivation layers on electrode materials are ubiquitous in nonaqueous battery
chemistries and strongly govern performance and lifetime. They comprise breakdown
products of the electrolyte including carbonate, alkyl carbonates, alkoxides,
carboxylates, and polymers. Parasitic chemistry in metal–O2 batteries forms similar
products and is tied to the deviation of the O2 balance from the ideal stoichiometry
during formation/decomposition of alkaline peroxides or superoxides. Accurate
and integral quantification of carbonaceous species and peroxides or superoxides
in battery electrodes remains, however, elusive. We present a refined procedure
to quantify them accurately and sensitively by pointing out and rectifying pitfalls
of previous procedures. Carbonaceous compounds are differentiated into inorganic
and organic ones. We combine mass and UV–vis spectrometry to quantify evolved
O2 and complexed peroxide and CO2 evolved from carbonaceous compounds by acid
treatment and Fenton’s reaction. The capabilities of the method are exemplified
by means of Li–O2 and Na–O2 cathodes, graphite anodes, and LiNi0.8Co0.15Al0.05O2
cathodes.

text: 'This paper is devoted to automatic competitive analysis of real-time scheduling
algorithms for firm-deadline tasksets, where only completed tasks con- tribute
some utility to the system. Given such a taskset T , the competitive ratio of
an on-line scheduling algorithm A for T is the worst-case utility ratio of A over
the utility achieved by a clairvoyant algorithm. We leverage the theory of quantitative
graph games to address the competitive analysis and competitive synthesis problems.
For the competitive analysis case, given any taskset T and any finite-memory on-
line scheduling algorithm A , we show that the competitive ratio of A in T can
be computed in polynomial time in the size of the state space of A . Our approach
is flexible as it also provides ways to model meaningful constraints on the released
task sequences that determine the competitive ratio. We provide an experimental
study of many well-known on-line scheduling algorithms, which demonstrates the
feasibility of our competitive analysis approach that effectively replaces human
ingenuity (required Preliminary versions of this paper have appeared in Chatterjee

synthesis case, we are just given a taskset T , and the goal is to automatically
synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees
the largest competitive ratio possible for T . We show how the competitive synthesis
problem can be reduced to a two-player graph game with partial information, and
establish that the compu- tational complexity of solving this game is Np -complete.
The competitive synthesis problem is hence in Np in the size of the state space
of the non-deterministic labeled transition system encoding the taskset. Overall,
the proposed framework assists in the selection of suitable scheduling algorithms
for a given taskset, which is in fact the most common situation in real-time systems
design. '

text: 'Proofs of space (PoS) [Dziembowski et al., CRYPTO''15] are proof systems
where a prover can convince a verifier that he "wastes" disk space. PoS were introduced
as a more ecological and economical replacement for proofs of work which are currently
used to secure blockchains like Bitcoin. In this work we investigate extensions
of PoS which allow the prover to embed useful data into the dedicated space, which
later can be recovered. Our first contribution is a security proof for the original
PoS from CRYPTO''15 in the random oracle model (the original proof only applied
to a restricted class of adversaries which can store a subset of the data an honest
prover would store). When this PoS is instantiated with recent constructions of
maximally depth robust graphs, our proof implies basically optimal security. As
a second contribution we show three different extensions of this PoS where useful
data can be embedded into the space required by the prover. Our security proof
for the PoS extends (non-trivially) to these constructions. We discuss how some
of these variants can be used as proofs of catalytic space (PoCS), a notion we
put forward in this work, and which basically is a PoS where most of the space
required by the prover can be used to backup useful data. Finally we discuss how
one of the extensions is a candidate construction for a proof of replication (PoR),
a proof system recently suggested in the Filecoin whitepaper. '

text: 'We give a detailed and easily accessible proof of Gromov’s Topological Overlap
Theorem. Let X be a finite simplicial complex or, more generally, a finite polyhedral
cell complex of dimension d. Informally, the theorem states that if X has sufficiently
strong higher-dimensional expansion properties (which generalize edge expansion
of graphs and are defined in terms of cellular cochains of X) then X has the following
topological overlap property: for every continuous map (Formula presented.) there
exists a point (Formula presented.) that is contained in the images of a positive
fraction (Formula presented.) of the d-cells of X. More generally, the conclusion
holds if (Formula presented.) is replaced by any d-dimensional piecewise-linear
manifold M, with a constant (Formula presented.) that depends only on d and on
the expansion properties of X, but not on M.'

text: The coupling between magnetic and electric subsystems in composites of ferromagnetic
and ferroelectric phases is a product property that is facilitated by mechanical
strain that arises due to magnetostriction and the piezoelectric effect in the
constituent phases. Such multiferroic composites are of immense interests for
studies on the physics of electromagnetic coupling and for use in a variety of
applications. Here, we focus on magneto-electric (ME) coupling in nanocomposites.
Particular emphasis is on core-shell particles and coaxial fibers, thin film heterostructures,
and planar structures with a variety of mechanical connectivity. A brief review
of models that predict strong ME effects in nanostructures is followed by synthesis
and characterization. Core-shell particulate composites can be prepared by hydrothermal
processes and chemical or deoxyribonucleic acid-assisted assembly. Electrospinning
techniques have been utilized to prepare defect free core-shell nanofibers. Core-shell
particles and fibers can be assembled into superstructures with the aid of magnetic
and electric fields and characterized for possible use in advanced technologies.
Chemical-vapor deposition techniques have been shown to be effective for the preparation
of heterostructures of ferrites and ferroelectrics. Exotic planar multiferroic
structures with potential for enhancing ME coupling strengths are also considered.
Scanning probe microscopy techniques are ideal for probing the nature of direct-
and converse-ME coupling in individual nanostructures. Magnetoelectric characterization
of assemblies of nanocomposites can be done by ME voltage coefficient, magnetic
field induced polarization, and magneto-dielectric effects. We conclude with a
brief discussion on possible avenues for strengthening the product properties
in the nanocomposites.

text: 'Consider a fully-connected synchronous distributed system consisting of n
nodes, where up to f nodes may be faulty and every node starts in an arbitrary
initial state. In the synchronous C-counting problem, all nodes need to eventually
agree on a counter that is increased by one modulo C in each round for given C>1.
In the self-stabilising firing squad problem, the task is to eventually guarantee
that all non-faulty nodes have simultaneous responses to external inputs: if a
subset of the correct nodes receive an external “go” signal as input, then all
correct nodes should agree on a round (in the not-too-distant future) in which
to jointly output a “fire” signal. Moreover, no node should generate a “fire”
signal without some correct node having previously received a “go” signal as input.
We present a framework reducing both tasks to binary consensus at very small cost.
For example, we obtain a deterministic algorithm for self-stabilising Byzantine
firing squads with optimal resilience f<n/3, asymptotically optimal stabilisation
and response time O(f), and message size O(log f). As our framework does not restrict
the type of consensus routines used, we also obtain efficient randomised solutions.'

text: Motor output varies along the rostro-caudal axis of the tetrapod spinal cord.
At limb levels, ∼60 motor pools control the alternation of flexor and extensor
muscles about each joint, whereas at thoracic levels as few as 10 motor pools
supply muscle groups that support posture, inspiration, and expiration. Whether
such differences in motor neuron identity and muscle number are associated with
segmental distinctions in interneuron diversity has not been resolved. We show
that select combinations of nineteen transcription factors that specify lumbar
V1 inhibitory interneurons generate subpopulations enriched at limb and thoracic
levels. Specification of limb and thoracic V1 interneurons involves the Hox gene
Hoxc9 independently of motor neurons. Thus, early Hox patterning of the spinal
cord determines the identity of V1 interneurons and motor neurons. These studies
reveal a developmental program of V1 interneuron diversity, providing insight
into the organization of inhibitory interneurons associated with differential
motor output.

text: Holes confined in quantum dots have gained considerable interest in the past
few years due to their potential as spin qubits. Here we demonstrate two-axis
control of a spin 3/2 qubit in natural Ge. The qubit is formed in a hut wire double
quantum dot device. The Pauli spin blockade principle allowed us to demonstrate
electric dipole spin resonance by applying a radio frequency electric field to
one of the electrodes defining the double quantum dot. Coherent hole spin oscillations
with Rabi frequencies reaching 140 MHz are demonstrated and dephasing times of
130 ns are measured. The reported results emphasize the potential of Ge as a platform
for fast and electrically tunable hole spin qubit devices.

text: 'Male pattern baldness (MPB) is a sex-limited, age-related, complex trait.
We study MPB genetics in 205,327 European males from the UK Biobank. Here we show
that MPB is strongly heritable and polygenic, with pedigree-heritability of 0.62
(SE = 0.03) estimated from close relatives, and SNP-heritability of 0.39 (SE = 0.01)
from conventionally-unrelated males. We detect 624 near-independent genome-wide
loci, contributing SNP-heritability of 0.25 (SE = 0.01), of which 26 X-chromosome
loci explain 11.6%. Autosomal genetic variance is enriched for common variants
and regions of lower linkage disequilibrium. We identify plausible genetic correlations
between MPB and multiple sex-limited markers of earlier puberty, increased bone
mineral density (rg = 0.15) and pancreatic β-cell function (rg = 0.12). Correlations
with reproductive traits imply an effect on fitness, consistent with an estimated
linear selection gradient of -0.018 per MPB standard deviation. Overall, we provide
genetic insights into MPB: a phenotype of interest in its own right, with value
as a model sex-limited, complex trait.'

text: There are mean differences in complex traits among global human populations.
We hypothesize that part of the phenotypic differentiation is due to natural selection.
To address this hypothesis, we assess the differentiation in allele frequencies
of trait-associated SNPs among African, Eastern Asian, and European populations
for ten complex traits using data of large sample size (up to ~405,000). We show
that SNPs associated with height (P=2.46×10−5), waist-to-hip ratio (P=2.77×10−4),
and schizophrenia (P=3.96×10−5) are significantly more differentiated among populations
than matched “control” SNPs, suggesting that these trait-associated SNPs have
undergone natural selection. We further find that SNPs associated with height
(P=2.01×10−6) and schizophrenia (P=5.16×10−18) show significantly higher variance
in linkage disequilibrium (LD) scores across populations than control SNPs. Our
results support the hypothesis that natural selection has shaped the genetic differentiation
of complex traits, such as height and schizophrenia, among worldwide populations.

text: Health risk factors such as body mass index (BMI) and serum cholesterol are
associated with many common diseases. It often remains unclear whether the risk
factors are cause or consequence of disease, or whether the associations are the
result of confounding. We develop and apply a method (called GSMR) that performs
a multi-SNP Mendelian randomization analysis using summary-level data from genome-wide
association studies to test the causal associations of BMI, waist-to-hip ratio,
serum cholesterols, blood pressures, height, and years of schooling (EduYears)
with common diseases (sample sizes of up to 405,072). We identify a number of
causal associations including a protective effect of LDL-cholesterol against type-2
diabetes (T2D) that might explain the side effects of statins on T2D, a protective
effect of EduYears against Alzheimer’s disease, and bidirectional associations
with opposite effects (e.g., higher BMI increases the risk of T2D but the effect
of T2D on BMI is negative).

text: Preference for mates with similar phenotypes; that is, assortative mating,
is widely observed in humans1,2,3,4,5 and has evolutionary consequences6,7,8.
Under Fisher's classical theory6, assortative mating is predicted to induce a
signature in the genome at trait-associated loci that can be detected and quantified.
Here, we develop and apply a method to quantify assortative mating on a specific
trait by estimating the correlation (θ) between genetic predictors of the trait
from single nucleotide polymorphisms on odd- versus even-numbered chromosomes.
We show by theory and simulation that the effect of assortative mating can be
quantified in the presence of population stratification. We applied this approach
to 32 complex traits and diseases using single nucleotide polymorphism data from
~400,000 unrelated individuals of European ancestry. We found significant evidence
of assortative mating for height (θ = 3.2%) and educational attainment (θ = 2.7%),
both of which were consistent with theoretical predictions. Overall, our results
imply that assortative mating involves multiple traits and affects the genomic
architecture of loci that are associated with these traits, and that the consequence
of mate choice can be detected from a random sample of genomes.

text: Genomic prediction has the potential to contribute to precision medicine.
However, to date, the utility of such predictors is limited due to low accuracy
for most traits. Here theory and simulation study are used to demonstrate that
widespread pleiotropy among phenotypes can be utilised to improve genomic risk
prediction. We show how a genetic predictor can be created as a weighted index
that combines published genome-wide association study (GWAS) summary statistics
across many different traits. We apply this framework to predict risk of schizophrenia
and bipolar disorder in the Psychiatric Genomics consortium data, finding substantial
heterogeneity in prediction accuracy increases across cohorts. For six additional
phenotypes in the UK Biobank data, we find increases in prediction accuracy ranging
from 0.7% for height to 47% for type 2 diabetes, when using a multi-trait predictor
that combines published summary statistics from multiple traits, as compared to
a predictor based only on one trait.
