text: Immunolocalization is a valuable tool for cell biology research that allows
to rapidly determine the localization and expression levels of endogenous proteins.
In plants, whole-mount in situ immunolocalization remains a challenging method,
especially in tissues protected by waxy layers and complex cell wall carbohydrates.
Here, we present a robust method for whole-mount in situ immunolocalization in
primary root meristems and lateral root primordia in Arabidopsis thaliana. For
good epitope preservation, fixation is done in an alkaline paraformaldehyde/glutaraldehyde
mixture. This fixative is suitable for detecting a wide range of proteins, including
integral transmembrane proteins and proteins peripherally attached to the plasma
membrane. From initiation until emergence from the primary root, lateral root
primordia are surrounded by several layers of differentiated tissues with a complex
cell wall composition that interferes with the efficient penetration of all buffers.
Therefore, immunolocalization in early lateral root primordia requires a modified
method, including a strong solvent treatment for removal of hydrophobic barriers
and a specific cocktail of cell wall-degrading enzymes. The presented method allows
for easy, reliable, and high-quality in situ detection of the subcellular localization
of endogenous proteins in primary and lateral root meristems without the need
of time-consuming crosses or making translational fusions to fluorescent proteins.

text: In 2013, a publication repository was implemented at IST Austria and 2015
after a thorough preparation phase a data repository was implemented - both based
on the Open Source Software EPrints. In this text, designed as field report, we
will reflect on our experiences with Open Source Software in general and specifically
with EPrints regarding technical aspects but also regarding their characteristics
of the user community. The second part is a pleading for including the end users
in the process of implementation, adaption and evaluation.

text: 'We consider the problem of consensus in the challenging classic model. In
this model, the adversary is adaptive; it can choose which processors crash at
any point during the course of the algorithm. Further, communication is via asynchronous
message passing: there is no known upper bound on the time to send a message from
one processor to another, and all messages and coin flips are seen by the adversary.
We describe a new randomized consensus protocol with expected message complexity
O(n2log2n) when fewer than n / 2 processes may fail by crashing. This is an almost-linear
improvement over the best previously known protocol, and within logarithmic factors
of a known Ω(n2) message lower bound. The protocol further ensures that no process
sends more than O(nlog3n) messages in expectation, which is again within logarithmic
factors of optimal. We also present a generalization of the algorithm to an arbitrary
number of failures t, which uses expected O(nt+t2log2t) total messages. Our approach
is to build a message-efficient, resilient mechanism for aggregating individual
processor votes, implementing the message-passing equivalent of a weak shared
coin. Roughly, in our protocol, a processor first announces its votes to small
groups, then propagates them to increasingly larger groups as it generates more
and more votes. To bound the number of messages that an individual process might
have to send or receive, the protocol progressively increases the weight of generated
votes. The main technical challenge is bounding the impact of votes that are still
“in flight” (generated, but not fully propagated) on the final outcome of the
shared coin, especially since such votes might have different weights. We achieve
this by leveraging the structure of the algorithm, and a technical argument based
on martingale concentration bounds. Overall, we show that it is possible to build
an efficient message-passing implementation of a shared coin, and in the process
(almost-optimally) solve the classic consensus problem in the asynchronous message-passing
model.'

text: Primary neuronal cell culture preparations are widely used to investigate
synaptic functions. This chapter describes a detailed protocol for the preparation
of a neuronal cell culture in which giant calyx-type synaptic terminals are formed.
This chapter also presents detailed protocols for utilizing the main technical
advantages provided by such a preparation, namely, labeling and imaging of synaptic
organelles and electrophysiological recordings directly from presynaptic terminals.

text: Graph-based games are an important tool in computer science. They have applications
in synthesis, verification, refinement, and far beyond. We review graphbased games
with objectives on infinite plays. We give definitions and algorithms to solve
the games and to give a winning strategy. The objectives we consider are mostly
Boolean, but we also look at quantitative graph-based games and their objectives.
Synthesis aims to turn temporal logic specifications into correct reactive systems.
We explain the reduction of synthesis to graph-based games (or equivalently tree
automata) using synthesis of LTL specifications as an example. We treat the classical
approach that uses determinization of parity automata and more modern approaches.

text: Model checking is a computer-assisted method for the analysis of dynamical
systems that can be modeled by state-transition systems. Drawing from research
traditions in mathematical logic, programming languages, hardware design, and
theoretical computer science, model checking is now widely used for the verification
of hardware and software in industry. This chapter is an introduction and short
survey of model checking. The chapter aims to motivate and link the individual
chapters of the handbook, and to provide context for readers who are not familiar
with model checking.

text: 'Neurons develop elaborate morphologies that provide a model for understanding
cellular architecture. By studying C. elegans sensory dendrites, we previously
identified genes that act to promote the extension of ciliated sensory dendrites
during embryogenesis. Interestingly, the nonciliated dendrite of the oxygen-sensing
neuron URX is not affected by these genes, suggesting it develops through a distinct
mechanism. Here, we use a visual forward genetic screen to identify mutants that
affect URX dendrite morphogenesis. We find that disruption of the MAP kinase MAPK-15
or the βH-spectrin SMA-1 causes a phenotype opposite to what we had seen before:
dendrites extend normally during embryogenesis but begin to overgrow as the animals
reach adulthood, ultimately extending up to 150% of their normal length. SMA-1
is broadly expressed and acts non-cell-autonomously, while MAPK-15 is expressed
in many sensory neurons including URX and acts cell-autonomously. MAPK-15 acts
at the time of overgrowth, localizes at the dendrite ending, and requires its
kinase activity, suggesting it acts locally in time and space to constrain dendrite
growth. Finally, we find that the oxygen-sensing guanylate cyclase GCY-35, which
normally localizes at the dendrite ending, is localized throughout the overgrown
region, and that overgrowth can be suppressed by overexpressing GCY-35 or by genetically
mimicking elevated cGMP signaling. These results suggest that overgrowth may correspond
to expansion of a sensory compartment at the dendrite ending, reminiscent of the
remodeling of sensory cilia or dendritic spines. Thus, in contrast to established
pathways that promote dendrite growth during early development, our results reveal
a distinct mechanism that constrains dendrite growth throughout the life of the
animal, possibly by controlling the size of a sensory compartment at the dendrite
ending.'

text: Neuropeptides are ubiquitous modulators of behavior and physiology. They are
packaged in specialized secretory organelles called dense core vesicles (DCVs)
that are released upon neural stimulation. Unlike synaptic vesicles, which can
be recycled and refilled close to release sites, DCVs must be replenished by de
novo synthesis in the cell body. Here, we dissect DCV cell biology in vivo in
a Caenorhabditis elegans sensory neuron whose tonic activity we can control using
a natural stimulus. We express fluorescently tagged neuropeptides in the neuron
and define parameters that describe their subcellular distribution. We measure
these parameters at high and low neural activity in 187 mutants defective in proteins
implicated in membrane traffic, neuroendocrine secretion, and neuronal or synaptic
activity. Using unsupervised hierarchical clustering methods, we analyze these
data and identify 62 groups of genes with similar mutant phenotypes. We explore
the function of a subset of these groups. We recapitulate many previous findings,
validating our paradigm. We uncover a large battery of proteins involved in recycling
DCV membrane proteins, something hitherto poorly explored. We show that the unfolded
protein response promotes DCV production, which may contribute to intertissue
communication of stress. We also find evidence that different mechanisms of priming
and exocytosis may operate at high and low neural activity. Our work provides
a defined framework to study DCV biology at different neural activity levels.

text: In this paper, we propose an algorithm to build discrete spherical shell having
integer center and real-valued inner and outer radii on the face-centered cubic
(FCC) grid. We address the problem by mapping it to a 2D scenario and building
the shell layer by layer on hexagonal grids with additive manufacturing in mind.
The layered hexagonal grids get shifted according to need as we move from one
layer to another and forms the FCC grid in 3D. However, we restrict our computation
strictly to 2D in order to utilize symmetry and simplicity.

text: Blood platelets are critical for hemostasis and thrombosis, but also play
diverse roles during immune responses. We have recently reported that platelets
migrate at sites of infection in vitro and in vivo. Importantly, platelets use
their ability to migrate to collect and bundle fibrin (ogen)-bound bacteria accomplishing
efficient intravascular bacterial trapping. Here, we describe a method that allows
analyzing platelet migration in vitro, focusing on their ability to collect bacteria
and trap bacteria under flow.

text: An optical network of superconducting quantum bits (qubits) is an appealing
platform for quantum communication and distributed quantum computing, but developing
a quantum-compatible link between the microwave and optical domains remains an
outstanding challenge. Operating at T < 100 mK temperatures, as required for quantum
electrical circuits, we demonstrate a mechanically mediated microwave–optical
converter with 47% conversion efficiency, and use a classical feed-forward protocol
to reduce added noise to 38 photons. The feed-forward protocol harnesses our discovery
that noise emitted from the two converter output ports is strongly correlated
because both outputs record thermal motion of the same mechanical mode. We also
discuss a quantum feed-forward protocol that, given high system efficiencies,
would allow quantum information to be transferred even when thermal phonons enter
the mechanical element faster than the electro-optic conversion rate.

text: We construct a metamaterial from radio-frequency harmonic oscillators, and
find two topologically distinct phases resulting from dissipation engineered into
the system. These phases are distinguished by a quantized value of bulk energy
transport. The impulse response of our circuit is measured and used to reconstruct
the band structure and winding number of circuit eigenfunctions around a dark
mode. Our results demonstrate that dissipative topological transport can occur
in a wider class of physical systems than considered before.

text: This chapter finds an agreement of equivariant indices of semi-classical homomorphisms
between pairwise mirror branes in the GL2 Higgs moduli space on a Riemann surface.
On one side of the agreement, components of the Lagrangian brane of U(1,1) Higgs
bundles, whose mirror was proposed by Hitchin to be certain even exterior powers
of the hyperholomorphic Dirac bundle on the SL2 Higgs moduli space, are present.
The agreement arises from a mysterious functional equation. This gives strong
computational evidence for Hitchin’s proposal.

text: Reed-Muller (RM) and polar codes are a class of capacity-achieving channel
coding schemes with the same factor graph representation. Low-complexity decoding
algorithms fall short in providing a good error-correction performance for RM
and polar codes. Using the symmetric group of RM and polar codes, the specific
decoding algorithm can be carried out on multiple permutations of the factor graph
to boost the error-correction performance. However, this approach results in high
decoding complexity. In this paper, we first derive the total number of factor
graph permutations on which the decoding can be performed. We further propose
a successive permutation (SP) scheme which finds the permutations on the fly,
thus the decoding always progresses on a single factor graph permutation. We show
that SP can be used to improve the error-correction performance of RM and polar
codes under successive-cancellation (SC) and SC list (SCL) decoding, while keeping
the memory requirements of the decoders unaltered. Our results for RM and polar
codes of length 128 and rate 0.5 show that when SP is used and at a target frame
error rate of 10 -4 , up to 0.5 dB and 0.1 dB improvement can be achieved for
RM and polar codes respectively.

text: Polar codes represent one of the major recent breakthroughs in coding theory
and, because of their attractive features, they have been selected for the incoming
5G standard. As such, a lot of attention has been devoted to the development of
decoding algorithms with good error performance and efficient hardware implementation.
One of the leading candidates in this regard is represented by successive-cancellation
list (SCL) decoding. However, its hardware implementation requires a large amount
of memory. Recently, a partitioned SCL (PSCL) decoder has been proposed to significantly
reduce the memory consumption. In this paper, we consider the paradigm of PSCL
decoding from a practical standpoint, and we provide several improvements. First,
by changing the target signal-to-noise ratio and consequently modifying the construction
of the code, we are able to improve the performance at no additional computational,
latency, or memory cost. Second, we bridge the performance gap between SCL and
PSCL decoding by introducing a generalized PSCL decoder and a layered PSCL decoder.
In this way, we obtain almost the same performance of the SCL decoder with a significantly
lower memory requirement, as testified by hardware implementation results. Third,
we present an optimal scheme to allocate cyclic redundancy checks. Finally, we
provide a lower bound on the list size that guarantees optimal maximum a posteriori
performance for the binary erasure channel.

text: Polar codes are a channel coding scheme for the next generation of wireless
communications standard (5G). The belief propagation (BP) decoder allows for parallel
decoding of polar codes, making it suitable for high throughput applications.
However, the error-correction performance of polar codes under BP decoding is
far from the requirements of 5G. It has been shown that the error-correction performance
of BP can be improved if the decoding is performed on multiple permuted factor
graphs of polar codes. However, a different BP decoding scheduling is required
for each factor graph permutation which results in the design of a different decoder
for each permutation. Moreover, the selection of the different factor graph permutations
is at random, which prevents the decoder to achieve a desirable error correction
performance with a small number of permutations. In this paper, we first show
that the permutations on the factor graph can be mapped into suitable permutations
on the codeword positions. As a result, we can make use of a single decoder for
all the permutations. In addition, we introduce a method to construct a set of
predetermined permutations which can provide the correct codeword if the decoding
fails on the original permutation. We show that for the 5G polar code of length
1024, the error-correction performance of the proposed decoder is more than 0.25
dB better than that of the BP decoder with the same number of random permutations
at the frame error rate of 10 -4 .

text: We survey coding techniques that enable reliable transmission at rates that
approach the capacity of an arbitrary discrete memoryless channel. In particular,
we take the point of view of modern coding theory and discuss how recent advances
in coding for symmetric channels help provide more efficient solutions for the
asymmetric case. We consider, in more detail, three basic coding paradigms. The
first one is Gallager's scheme that consists of concatenating a linear code with
a non-linear mapping so that the input distribution can be appropriately shaped.
We explicitly show that both polar codes and spatially coupled codes can be employed
in this scenario. Furthermore, we derive a scaling law between the gap to capacity,
the cardinality of the input and output alphabets, and the required size of the
mapper. The second one is an integrated scheme in which the code is used both
for source coding, in order to create codewords distributed according to the capacity-achieving
input distribution, and for channel coding, in order to provide error protection.
Such a technique has been recently introduced by Honda and Yamamoto in the context
of polar codes, and we show how to apply it also to the design of sparse graph
codes. The third paradigm is based on an idea of Böcherer and Mathar, and separates
the two tasks of source coding and channel coding by a chaining construction that
binds together several codewords. We present conditions for the source code and
the channel code, and we describe how to combine any source code with any channel
code that fulfill those conditions, in order to provide capacity-achieving schemes
for asymmetric channels. In particular, we show that polar codes, spatially coupled
codes, and homophonic codes are suitable as basic building blocks of the proposed
coding strategy. Rather than focusing on the exact details of the schemes, the
purpose of this tutorial is to present different coding techniques that can then
be implemented with many variants. There is no absolute winner and, in order to
understand the most suitable technique for a specific application scenario, we
provide a detailed comparison that takes into account several performance metrics.

text: We consider spectral properties and the edge universality of sparse random
matrices, the class of random matrices that includes the adjacency matrices of
the Erdős–Rényi graph model G(N, p). We prove a local law for the eigenvalue density
up to the spectral edges. Under a suitable condition on the sparsity, we also
prove that the rescaled extremal eigenvalues exhibit GOE Tracy–Widom fluctuations
if a deterministic shift of the spectral edge due to the sparsity is included.
For the adjacency matrix of the Erdős–Rényi graph this establishes the Tracy–Widom
fluctuations of the second largest eigenvalue when p is much larger than N−2/3
with a deterministic shift of order (Np)−1.

text: 'We present a coding paradigm that provides a new achievable rate for the
primitive relay channel by combining compress-and-forward and decode-and-forward
with a chaining construction. In the primitive relay channel model, the source
broadcasts a message to the relay and to the destination; and the relay facilitates
this communication by sending an additional message to the destination through
a separate channel. Two well-known coding approaches for this setting are decode-and-forward
and compress-and-forward: in the former, the relay decodes the message and sends
some of the information to the destination; in the latter, the relay does not
attempt to decode, but it sends a compressed description of the received sequence
to the destination via Wyner-Ziv coding. In our scheme, we transmit over pairs
of blocks and we use compress-and-forward for the first block and decode-and-forward
for the second. In particular, in the first block, the relay does not attempt
to decode and it sends only a part of the compressed description of the received
sequence; in the second block, the relay decodes the message and sends this information
plus the remaining part of the compressed sequence relative to the first block.
As a result, we strictly outperform both compress-and- forward and decode-and-forward.
Furthermore, this paradigm can be implemented with a low-complexity polar coding
scheme that has the typical attractive features of polar codes, i.e., quasi-linear
encoding/decoding complexity and super-polynomial decay of the error probability.
Throughout the paper we consider as a running example the special case of the
erasure relay channel and we compare the rates achievable by our proposed scheme
with the existing upper and lower bounds.'

text: We consider the NP-hard problem of MAP-inference for undirected discrete graphical
models. We propose a polynomial time and practically efficient algorithm for finding
a part of its optimal solution. Specifically, our algorithm marks some labels
of the considered graphical model either as (i) optimal, meaning that they belong
to all optimal solutions of the inference problem; (ii) non-optimal if they provably
do not belong to any solution. With access to an exact solver of a linear programming
relaxation to the MAP-inference problem, our algorithm marks the maximal possible
(in a specified sense) number of labels. We also present a version of the algorithm,
which has access to a suboptimal dual solver only and still can ensure the (non-)optimality
for the marked labels, although the overall number of the marked labels may decrease.
We propose an efficient implementation, which runs in time comparable to a single
run of a suboptimal dual solver. Our method is well-scalable and shows state-of-the-art
results on computational benchmarks from machine learning and computer vision.

text: The high-pressure synthesis and incommensurately modulated structure are reported
for the new compound Sr2Pt8−xAs, with x = 0.715 (5). The structure consists of
Sr2Pt3As layers alternating with Pt-only corrugated grids. Ab initio calculations
predict a metallic character with a dominant role of the Pt d electrons. The electrical
resistivity (ρ) and Seebeck coefficient confirm the metallic character, but surprisingly,
ρ showed a near-flat temperature dependence. This observation fits the description
of the Mooij correlation for electrical resistivity in disordered metals, originally
developed for statistically distributed point defects. The discussed material
has a long-range crystallographic order, but the high concentration of Pt vacancies,
incommensurately ordered, strongly influences the electronic conduction properties.
This result extends the range of validity of the Mooij correlation to long-range
ordered incommensurately modulated vacancies. Motivated by the layered structure,
the resistivity anisotropy was measured in a focused-ion-beam micro-fabricated
well oriented single crystal. A low resistivity anisotropy indicates that the
layers are electrically coupled and conduction channels along different directions
are intermixed.

text: 'Weyl fermions are a recently discovered ingredient for correlated states
of electronic matter. A key difficulty has been that real materials also contain
non-Weyl quasiparticles, and disentangling the experimental signatures has proven
challenging. Here we use magnetic fields up to 95 T to drive the Weyl semimetal
TaAs far into its quantum limit, where only the purely chiral 0th Landau levels
of the Weyl fermions are occupied. We find the electrical resistivity to be nearly
independent of magnetic field up to 50 T: unusual for conventional metals but
consistent with the chiral anomaly for Weyl fermions. Above 50 T we observe a
two-order-of-magnitude increase in resistivity, indicating that a gap opens in
the chiral Landau levels. Above 80 T we observe strong ultrasonic attenuation
below 2 K, suggesting a mesoscopically textured state of matter. These results
point the way to inducing new correlated states of matter in the quantum limit
of Weyl semimetals.'

text: Unusual behavior in quantum materials commonly arises from their effective
low-dimensional physics, reflecting the underlying anisotropy in the spin and
charge degrees of freedom. Here we introduce the magnetotropic coefficient k = ∂2F/∂θ2,
the second derivative of the free energy F with respect to the magnetic field
orientation θ in the crystal. We show that the magnetotropic coefficient can be
quantitatively determined from a shift in the resonant frequency of a commercially
available atomic force microscopy cantilever under magnetic field. This detection
method enables part per 100 million sensitivity and the ability to measure magnetic
anisotropy in nanogram-scale samples, as demonstrated on the Weyl semimetal NbP.
Measurement of the magnetotropic coefficient in the spin-liquid candidate RuCl3
highlights its sensitivity to anisotropic phase transitions and allows a quantitative
comparison to other thermodynamic coefficients via the Ehrenfest relations.

text: We examine recent magnetic torque measurements in two compounds, γ−Li2IrO3
and RuCl3, which have been discussed as possible realizations of the Kitaev model.
The analysis of the reported discontinuity in torque, as an external magnetic
field is rotated across the c axis in both crystals, suggests that they have a
translationally invariant chiral spin order of the form ⟨Si⋅(Sj×Sk)⟩≠0 in the
ground state and persisting over a very wide range of magnetic field and temperature.
An extraordinary |B|B2 dependence of the torque for small fields, beside the usual
B2 part, is predicted by the chiral spin order. Data for small fields are available
for γ−Li2IrO3 and are found to be consistent with the prediction upon further
analysis. Other experiments such as inelastic scattering and thermal Hall effect
and several questions raised by the discovery of chiral spin order, including
its topological consequences, are discussed.

text: The anomalous metallic state in the high-temperature superconducting cuprates
is masked by superconductivity near a quantum critical point. Applying high magnetic
fields to suppress superconductivity has enabled detailed studies of the normal
state, yet the direct effect of strong magnetic fields on the metallic state is
poorly understood. We report the high-field magnetoresistance of thin-film La2–xSrxCuO4
cuprate in the vicinity of the critical doping, 0.161 ≤ p ≤ 0.190. We find that
the metallic state exposed by suppressing superconductivity is characterized by
magnetoresistance that is linear in magnetic fields up to 80 tesla. The magnitude
of the linear-in-field resistivity mirrors the magnitude and doping evolution
of the well-known linear-in-temperature resistivity that has been associated with
quantum criticality in high-temperature superconductors.

text: 'Training deep learning models has received tremendous research interest recently.
In particular, there has been intensive research on reducing the communication
cost of training when using multiple computational devices, through reducing the
precision of the underlying data representation. Naturally, such methods induce
system trade-offs—lowering communication precision could de-crease communication
overheads and improve scalability; but, on the other hand, it can also reduce
the accuracy of training. In this paper, we study this trade-off space, and ask:Can
low-precision communication consistently improve the end-to-end performance of
training modern neural networks, with no accuracy loss?From the performance point
of view, the answer to this question may appear deceptively easy: compressing
communication through low precision should help when the ratio between communication
and computation is high. However, this answer is less straightforward when we
try to generalize this principle across various neural network architectures (e.g.,
AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g.,
EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL),
and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is
not clear how a realistic realization of all these factors maps to the speed up
provided by low-precision communication. In this paper, we conduct an empirical
study to answer this question and report the insights.'

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: '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: 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: 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: 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: '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: 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: "Background: DNA methylation levels change along with age, but few studies
have examined the variation in the rate of such changes between individuals.\r\nMethods:
We performed a longitudinal analysis to quantify the variation in the rate of
change of DNA methylation between individuals using whole blood DNA methylation
array profiles collected at 2–4 time points (N = 2894) in 954 individuals (67–90
years).\r\nResults: After stringent quality control, we identified 1507 DNA methylation
CpG sites (rsCpGs) with statistically significant variation in the rate of change
(random slope) of DNA methylation among individuals in a mixed linear model analysis.
Genes in the vicinity of these rsCpGs were found to be enriched in Homeobox transcription
factors and the Wnt signalling pathway, both of which are related to ageing processes.
Furthermore, we investigated the SNP effect on the random slope. We found that
4 out of 1507 rsCpGs had one significant (P < 5 × 10−8/1507) SNP effect and 343
rsCpGs had at least one SNP effect (436 SNP-probe pairs) reaching genome-wide
significance (P < 5 × 10−8). Ninety-five percent of the significant (P < 5 × 10−8)
SNPs are on different chromosomes from their corresponding probes.\r\nConclusions:
We identified CpG sites that have variability in the rate of change of DNA methylation
between individuals, and our results suggest a genetic basis of this variation.
Genes around these CpG sites have been reported to be involved in the ageing process."

text: Flores Island, Indonesia, was inhabited by the small-bodied hominin species
Homo floresiensis, which has an unknown evolutionary relationship to modern humans.
This island is also home to an extant human pygmy population. Here we describe
genome-scale single-nucleotide polymorphism data and whole-genome sequences from
a contemporary human pygmy population living on Flores near the cave where H.
floresiensis was found. The genomes of Flores pygmies reveal a complex history
of admixture with Denisovans and Neanderthals but no evidence for gene flow with
other archaic hominins. Modern individuals bear the signatures of recent positive
selection encompassing the FADS (fatty acid desaturase) gene cluster, likely related
to diet, and polygenic selection acting on standing variation that contributed
to their short-stature phenotype. Thus, multiple independent instances of hominin
insular dwarfism occurred on Flores.

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: 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.

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: 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: 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: 'The availability of genome-wide genetic data on hundreds of thousands of
people has led to an equally rapid growth in methodologies available to analyse
these data. While the motivation for undertaking genome-wide association studies
(GWAS) is identification of genetic markers associated with complex traits, once
generated these data can be used for many other analyses. GWAS have demonstrated
that complex traits exhibit a highly polygenic genetic architecture, often with
shared genetic risk factors across traits. New methods to analyse data from GWAS
are increasingly being used to address a diverse set of questions about the aetiology
of complex traits and diseases, including psychiatric disorders. Here, we give
an overview of some of these methods and present examples of how they have contributed
to our understanding of psychiatric disorders. We consider: (i) estimation of
the extent of genetic influence on traits, (ii) uncovering of shared genetic control
between traits, (iii) predictions of genetic risk for individuals, (iv) uncovering
of causal relationships between traits, (v) identifying causal single-nucleotide
polymorphisms and genes or (vi) the detection of genetic heterogeneity. This classification
helps organise the large number of recently developed methods, although some could
be placed in more than one category. While some methods require GWAS data on individual
people, others simply use GWAS summary statistics data, allowing novel well-powered
analyses to be conducted at a low computational burden.'

text: Genome-wide association studies (GWAS) have identified thousands of loci that
are robustly associated with complex diseases. The use of linear mixed model (LMM)
methodology for GWAS is becoming more prevalent due to its ability to control
for population structure and cryptic relatedness and to increase power. The odds
ratio (OR) is a common measure of the association of a disease with an exposure
(e.g., a genetic variant) and is readably available from logistic regression.
However, when the LMM is applied to all-or-none traits it provides estimates of
genetic effects on the observed 0–1 scale, a different scale to that in logistic
regression. This limits the comparability of results across studies, for example
in a meta-analysis, and makes the interpretation of the magnitude of an effect
from an LMM GWAS difficult. In this study, we derived transformations from the
genetic effects estimated under the LMM to the OR that only rely on summary statistics.
To test the proposed transformations, we used real genotypes from two large, publicly
available data sets to simulate all-or-none phenotypes for a set of scenarios
that differ in underlying model, disease prevalence, and heritability. Furthermore,
we applied these transformations to GWAS summary statistics for type 2 diabetes
generated from 108,042 individuals in the UK Biobank. In both simulation and real-data
application, we observed very high concordance between the transformed OR from
the LMM and either the simulated truth or estimates from logistic regression.
The transformations derived and validated in this study improve the comparability
of results from prospective and already performed LMM GWAS on complex diseases
by providing a reliable transformation to a common comparative scale for the genetic
effects.

text: We develop a Bayesian mixed linear model that simultaneously estimates single-nucleotide
polymorphism (SNP)-based heritability, polygenicity (proportion of SNPs with nonzero
effects), and the relationship between SNP effect size and minor allele frequency
for complex traits in conventionally unrelated individuals using genome-wide SNP
data. We apply the method to 28 complex traits in the UK Biobank data (N = 126,752)
and show that on average, 6% of SNPs have nonzero effects, which in total explain
22% of phenotypic variance. We detect significant (P < 0.05/28) signatures of
natural selection in the genetic architecture of 23 traits, including reproductive,
cardiovascular, and anthropometric traits, as well as educational attainment.
The significant estimates of the relationship between effect size and minor allele
frequency in complex traits are consistent with a model of negative (or purifying)
selection, as confirmed by forward simulation. We conclude that negative selection
acts pervasively on the genetic variants associated with human complex traits.

text: Modern molecular genetic datasets, primarily collected to study the biology
of human health and disease, can be used to directly measure the action of natural
selection and reveal important features of contemporary human evolution. Here
we leverage the UK Biobank data to test for the presence of linear and nonlinear
natural selection in a contemporary population of the United Kingdom. We obtain
phenotypic and genetic evidence consistent with the action of linear/directional
selection. Phenotypic evidence suggests that stabilizing selection, which acts
to reduce variance in the population without necessarily modifying the population
mean, is widespread and relatively weak in comparison with estimates from other
species.

text: Creating a selective gel that filters particles based on their interactions
is a major goal of nanotechnology, with far-reaching implications from drug delivery
to controlling assembly pathways. However, this is particularly difficult when
the particles are larger than the gel’s characteristic mesh size because such
particles cannot passively pass through the gel. Thus, filtering requires the
interacting particles to transiently reorganize the gel’s internal structure.
While significant advances, e.g., in DNA engineering, have enabled the design
of nano-materials with programmable interactions, it is not clear what physical
principles such a designer gel could exploit to achieve selective permeability.
We present an equilibrium mechanism where crosslink binding dynamics are affected
by interacting particles such that particle diffusion is enhanced. In addition
to revealing specific design rules for manufacturing selective gels, our results
have the potential to explain the origin of selective permeability in certain
biological materials, including the nuclear pore complex.
