text: Transcription of eukaryotic protein-coding genes commences with the assembly
of a conserved initiation complex, which consists of RNA polymerase II (Pol II)
and the general transcription factors, at promoter DNA. After two decades of research,
the structural basis of transcription initiation is emerging. Crystal structures
of many components of the initiation complex have been resolved, and structural
information on Pol II complexes with general transcription factors has recently
been obtained. Although mechanistic details await elucidation, available data
outline how Pol II cooperates with the general transcription factors to bind to
and open promoter DNA, and how Pol II directs RNA synthesis and escapes from the
promoter.

text: 'Carbon dioxide (CO2) gradients are ubiquitous and provide animals with information
about their environment, such as the potential presence of prey or predators.
The nematode Caenorhabditis elegans avoids elevated CO2, and previous work identified
three neuron pairs called “BAG,” “AFD,” and “ASE” that respond to CO2 stimuli.
Using in vivo Ca2+ imaging and behavioral analysis, we show that C. elegans can
detect CO2 independently of these sensory pathways. Many of the C. elegans sensory
neurons we examined, including the AWC olfactory neurons, the ASJ and ASK gustatory
neurons, and the ASH and ADL nociceptors, respond to a rise in CO2 with a rise
in Ca2+. In contrast, glial sheath cells harboring the sensory endings of C. elegans’
major chemosensory neurons exhibit strong and sustained decreases in Ca2+ in response
to high CO2. Some of these CO2 responses appear to be cell intrinsic. Worms therefore
may couple detection of CO2 to that of other cues at the earliest stages of sensory
processing. We show that C. elegans persistently suppresses oviposition at high
CO2. Hermaphrodite-specific neurons (HSNs), the executive neurons driving egg-laying,
are tonically inhibited when CO2 is elevated. CO2 modulates the egg-laying system
partly through the AWC olfactory neurons: High CO2 tonically activates AWC by
a cGMP-dependent mechanism, and AWC output inhibits the HSNs. Our work shows that
CO2 is a more complex sensory cue for C. elegans than previously thought, both
in terms of behavior and neural circuitry.'

text: Brains organize behavior and physiology to optimize the response to threats
or opportunities. We dissect how 21% O2, an indicator of surface exposure, reprograms
C. elegans' global state, inducing sustained locomotory arousal and altering expression
of neuropeptides, metabolic enzymes, and other non-neural genes. The URX O2-sensing
neurons drive arousal at 21% O2 by tonically activating the RMG interneurons.
Stimulating RMG is sufficient to switch behavioral state. Ablating the ASH, ADL,
or ASK sensory neurons connected to RMG by gap junctions does not disrupt arousal.
However, disrupting cation currents in these neurons curtails RMG neurosecretion
and arousal. RMG signals high O2 by peptidergic secretion. Neuropeptide reporters
reveal neural circuit state, as neurosecretion stimulates neuropeptide expression.
Neural imaging in unrestrained animals shows that URX and RMG encode O2 concentration
rather than behavior, while the activity of downstream interneurons such as AVB
and AIY reflect both O2 levels and the behavior being executed.

text: The osteoclast-associated receptor (OSCAR) is a collagen-binding immune receptor
with important roles in dendritic cell maturation and activation of inflammatory
monocytes as well as in osteoclastogenesis. The crystal structure of the OSCAR
ectodomain is presented, both free and in complex with a consensus triple-helical
peptide (THP). The structures revealed a collagen-binding site in each immunoglobulin-like
domain (D1 and D2). The THP binds near a predicted collagen-binding groove in
D1, but a more extensive interaction with D2 is facilitated by the unusually wide
D1-D2 interdomain angle in OSCAR. Direct binding assays, combined with site-directed
mutagenesis, confirm that the primary collagen-binding site in OSCAR resides in
D2, in marked contrast to the related collagen receptors, glycoprotein VI (GPVI)
and leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1). Monomeric OSCAR
D1D2 binds to the consensus THP with a KD of 28 µM measured in solution, but shows
a higher affinity (KD 1.5 μM) when binding to a solid-phase THP, most likely due
to an avidity effect. These data suggest a 2-stage model for the interaction of
OSCAR with a collagen fibril, with transient, low-affinity interactions initiated
by the membrane-distal D1, followed by firm adhesion to the primary binding site
in D2.

text: Motivated by the significant performance gains which polar codes experience
under successive cancellation list decoding, their scaling exponent is studied
as a function of the list size. In particular, the error probability is fixed,
and the tradeoff between the block length and back-off from capacity is analyzed.
A lower bound is provided on the error probability under MAP decoding with list
size L for any binary-input memoryless output-symmetric channel and for any class
of linear codes such that their minimum distance is unbounded as the block length
grows large. Then, it is shown that under MAP decoding, although the introduction
of a list can significantly improve the involved constants, the scaling exponent
itself, i.e., the speed at which capacity is approached, stays unaffected for
any finite list size. In particular, this result applies to polar codes, since
their minimum distance tends to infinity as the block length increases. A similar
result is proved for genie-aided successive cancellation decoding when transmission
takes place over the binary erasure channel, namely, the scaling exponent remains
constant for any fixed number of helps from the genie. Note that since genie-aided
successive cancellation decoding might be strictly worse than successive cancellation
list decoding, the problem of establishing the scaling exponent of the latter
remains open.

text: This paper presents polar coding schemes for the two-user discrete memoryless
broadcast channel (DM-BC) which achieve Marton's region with both common and private
messages. This is the best achievable rate region known to date, and it is tight
for all classes of two-user DM-BCs whose capacity regions are known. To accomplish
this task, we first construct polar codes for both the superposition as well as
binning strategy. By combining these two schemes, we obtain Marton's region with
private messages only. Finally, we show how to handle the case of common information.
The proposed coding schemes possess the usual advantages of polar codes, i.e.,
they have low encoding and decoding complexity and a superpolynomial decay rate
of the error probability. We follow the lead of Goela, Abbe, and Gastpar, who
recently introduced polar codes emulating the superposition and binning schemes.
To align the polar indices, for both schemes, their solution involves some degradedness
constraints that are assumed to hold between the auxiliary random variables and
channel outputs. To remove these constraints, we consider the transmission of
k blocks and employ a chaining construction that guarantees the proper alignment
of the polarized indices. The techniques described in this paper are quite general,
and they can be adopted to many other multiterminal scenarios whenever there polar
indices need to be aligned.

text: 'Torque magnetization measurements on YBa2Cu3Oy (YBCO) at doping y=6.67 (p=0.12),
in dc fields (B) up to 33 T and temperatures down to 4.5 K, show that weak diamagnetism
persists above the extrapolated irreversibility field Hirr(T=0)≈24 T. The differential
susceptibility dM/dB, however, is more rapidly suppressed for B≳16 T than expected
from the properties of the low field superconducting state, and saturates at a
low value for fields B≳24 T. In addition, torque measurements on a p=0.11 YBCO
crystal in pulsed field up to 65 T and temperatures down to 8 K show similar behavior,
with no additional features at higher fields. We offer two candidate scenarios
to explain these observations: (a) superconductivity survives but is heavily suppressed
at high field by competition with charge-density-wave (CDW) order; (b) static
superconductivity disappears near 24 T and is followed by a region of fluctuating
superconductivity, which causes dM/dB to saturate at high field. The diamagnetic
signal observed above 50 T for the p=0.11 crystal at 40 K and below may be caused
by changes in the normal state susceptibility rather than bulk or fluctuating
superconductivity. There will be orbital (Landau) diamagnetism from electron pockets
and possibly a reduction in spin susceptibility caused by the stronger three-dimensional
ordered CDW.'

text: The rational design of monodisperse ferroelectric nanocrystals with controlled
size and shape and their organization into hierarchical structures has been a
critical step for understanding the polar ordering in nanoscale ferroelectrics,
as well as the design of nanocrystal-based functional materials which harness
the properties of individual nanoparticles and the collective interactions between
them. We report here on the synthesis and self-assembly of aggregate-free, single-crystalline
titanium-based perovskite nanoparticles with controlled morphology and surface
composition by using a simple, easily scalable and highly versatile colloidal
route. Single-crystalline, non-aggregated BaTiO3 colloidal nanocrystals, used
as a model system, have been prepared under solvothermal conditions at temperatures
as low as 180 °C. The shape of the nanocrystals was tuned from spheroidal to cubic
upon changing the polarity of the solvent, whereas their size was varied from
16 to 30 nm for spheres and 5 to 78 nm for cubes by changing the concentration
of the precursors and the reaction time, respectively. The hydrophobic, oleic
acid-passivated nanoparticles exhibit very good solubility in non-polar solvents
and can be rendered dispersible in polar solvents by a simple process involving
the oxidative cleavage of the double bond upon treating the nanopowders with the
Lemieux–von Rudloff reagent. Lattice dynamic analysis indicated that regardless
of their size, BaTiO3 nanocrystals present local disorder within the perovskite
unit cell, associated with the existence of polar ordering. We also demonstrate
for the first time that, in addition to being used for fabricating large area,
crack-free, highly uniform films, BaTiO3 nanocubes can serve as building blocks
for the design of 2D and 3D mesoscale structures, such as superlattices and superparticles.
Interestingly, the type of superlattice structure (simple cubic or face centered
cubic) appears to be determined by the type of solvent in which the nanocrystals
were dispersed. This approach provides an excellent platform for the synthesis
of other titanium-based perovskite colloidal nanocrystals with controlled chemical
composition, surface structure and morphology and for their assembly into complex
architectures, therefore opening the door for the design of novel mesoscale functional
materials/nanocomposites with potential applications in energy conversion, data
storage and the biomedical field.

text: A new organic–inorganic ferroelectric hybrid capacitor designed by uniformly
incorporating surface modified monodisperse 15 nm ferroelectric BaTiO3 nanocubes
into non-polar polymer blends of poly(methyl methacrylate) (PMMA) polymer and
acrylonitrile-butadiene-styrene (ABS) terpolymer is described. The investigation
of spatial distribution of nanofillers via a non-distractive thermal pulse method
illustrates that the surface functionalization of nanocubes plays a key role in
the uniform distribution of charge polarization within the polymer matrix. The
discharged energy density of the nanocomposite with 30 vol% BaTiO3 nanocubes is
∼44 × 10−3 J cm−3, which is almost six times higher than that of the neat polymer.
The facile processing, along with the superior mechanical and electrical properties
of the BaTiO3/PMMA–ABS nanocomposites make them suitable for implementation into
capacitive electrical energy storage devices.

text: We propose a new approach to probing ergodicity and its breakdown in one-dimensional
quantum manybody systems based on their response to a local perturbation. We study
the distribution of matrix elements of a local operator between the system's eigenstates,
finding a qualitatively different behavior in the manybody localized (MBL) and
ergodic phases. To characterize how strongly a local perturbation modifies the
eigenstates, we introduce the parameter g(L) = (In (Vnm/δ)) which represents the
disorder-averaged ratio of a typical matrix element of a local operator V to energy
level spacing δ this parameter is reminiscent of the Thouless conductance in the
single-particle localization. We show that the parameter g(L) decreases with system
size L in the MBL phase and grows in the ergodic phase. We surmise that the delocalization
transition occurs when g(L) is independent of system size, g(L)=gc ~ 1. We illustrate
our approach by studying the many-body localization transition and resolving the
many-body mobility edge in a disordered one-dimensional XXZ spin-1=2 chain using
exact diagonalization and time-evolving block-decimation methods. Our criterion
for the MBL transition gives insights into microscopic details of transition.
Its direct physical consequences, in particular, logarithmically slow transport
at the transition and extensive entanglement entropy of the eigenstates, are consistent
with recent renormalization-group predictions.

text: Quasiparticle excitations can compromise the performance of superconducting
devices, causing high-frequency dissipation, decoherence in Josephson qubits,
and braiding errors in proposed Majorana-based topological quantum computers.
Quasiparticle dynamics have been studied in detail in metallic superconductors
but remain relatively unexplored in semiconductor-superconductor structures, which
are now being intensely pursued in the context of topological superconductivity.
To this end, we use a system comprising a gate-confined semiconductor nanowire
with an epitaxially grown superconductor layer, yielding an isolated, proximitized
nanowire segment. We identify bound states in the semiconductor by means of bias
spectroscopy, determine the characteristic temperatures and magnetic fields for
quasiparticle excitations, and extract a parity lifetime (poisoning time) of the
bound state in the semiconductor exceeding 10 ms.

text: 'A simple and effective method to introduce precise amounts of doping in nanomaterials
produced from the bottom-up assembly of colloidal nanoparticles (NPs) is described.
The procedure takes advantage of a ligand displacement step to incorporate controlled
concentrations of halide ions while removing carboxylic acids from the NP surface.
Upon consolidation of the NPs into dense pellets, halide ions diffuse within the
crystal structure, doping the anion sublattice and achieving n-type electrical
doping. Through the characterization of the thermoelectric properties of nanocrystalline
PbS, we demonstrate this strategy to be effective to control charge transport
properties on thermoelectric nanomaterials assembled from NP building blocks.
This approach is subsequently extended to PbTexSe1-x@PbS core-shell NPs, where
a significant enhancement of the thermoelectric figure of merit is achieved. '

text: We report the synthesis and photocatalytic and magnetic characterization of
colloidal nanoheterostructures formed by combining a Pt-based magnetic metal alloy
(PtCo, PtNi) with Cu2ZnSnS4 (CZTS). While CZTS is one of the main candidate materials
for solar energy conversion, the introduction of a Pt-based alloy on its surface
strongly influences its chemical and electronic properties, ultimately determining
its functionality. In this regard, up to a 15-fold increase of the photocatalytic
hydrogen evolution activity was obtained with CZTS–PtCo when compared with CZTS.
Furthermore, two times higher hydrogen evolution rates were obtained for CZTS–PtCo
when compared with CZTS–Pt, in spite of the lower precious metal loading of the
former. Besides, the magnetic properties of the PtCo nanoparticles attached to
the CZTS nanocrystals were retained in the heterostructures, which could facilitate
catalyst purification and recovery for its posterior recycling and/or reutilization.

text: 'Monodisperse Pd2Sn nanorods with tuned size and aspect ratio were prepared
by co-reduction of metal salts in the presence of trioctylphosphine, amine, and
chloride ions. Asymmetric Pd2Sn nanostructures were achieved by the selective
desorption of a surfactant mediated by chlorine ions. A preliminary evaluation
of the geometry influence on catalytic properties evidenced Pd2Sn nanorods to
have improved catalytic performance. In view of these results, Pd2Sn nanorods
were also evaluated for water denitration. '

text: We use ultrafast optical spectroscopy to observe binding of charged single-particle
excitations (SE) in the magnetically frustrated Mott insulator Na2IrO3. Above
the antiferromagnetic ordering temperature (TN) the system response is due to
both Hubbard excitons (HE) and their constituent unpaired SE. The SE response
becomes strongly suppressed immediately below TN. We argue that this increase
in binding energy is due to a unique interplay between the frustrated Kitaev and
the weak Heisenberg-type ordering term in the Hamiltonian, mediating an effective
interaction between the spin-singlet SE. This interaction grows with distance
causing the SE to become trapped in the HE, similar to quark confinement inside
hadrons. This binding of charged particles, induced by magnetic ordering, is a
result of a confinement-deconfinement transition of spin excitations. This observation
provides evidence for spin liquid type behavior which is expected in Na2IrO3.

text: "We study conditions under which a finite simplicial complex $K$ can be mapped
to $\\mathbb R^d$ without higher-multiplicity intersections. An almost $r$-embedding
is a map $f: K\\to \\mathbb R^d$ such that the images of any $r$\r\npairwise disjoint
simplices of $K$ do not have a common point. We show that if $r$ is not a prime
power and $d\\geq 2r+1$, then there is a counterexample to the topological Tverberg
conjecture, i.e., there is an almost $r$-embedding of\r\nthe $(d+1)(r-1)$-simplex
in $\\mathbb R^d$. This improves on previous constructions of counterexamples
(for $d\\geq 3r$) based on a series of papers by M. \\\"Ozaydin, M. Gromov, P.
Blagojevi\\'c, F. Frick, G. Ziegler, and the second and fourth present authors.
The counterexamples are obtained by proving the following algebraic criterion
in codimension 2: If $r\\ge3$ and if $K$ is a finite $2(r-1)$-complex then there
exists an almost $r$-embedding $K\\to \\mathbb R^{2r}$ if and only if there exists
a general position PL map $f:K\\to \\mathbb R^{2r}$ such that the algebraic intersection
number of the $f$-images of any $r$ pairwise disjoint simplices of $K$ is zero.
This result can be restated in terms of cohomological obstructions or equivariant
maps, and extends an analogous codimension 3 criterion by the second and fourth
authors. As another application we classify ornaments $f:S^3 \\sqcup S^3\\sqcup
S^3\\to \\mathbb R^5$ up to ornament\r\nconcordance. It follows from work of M.
Freedman, V. Krushkal and P. Teichner that the analogous criterion for $r=2$ is
false. We prove a lemma on singular higher-dimensional Borromean rings, yielding
an elementary proof of the counterexample."

text: 'Gene expression is controlled primarily by interactions between transcription
factor proteins (TFs) and the regulatory DNA sequence, a process that can be captured
well by thermodynamic models of regulation. These models, however, neglect regulatory
crosstalk: the possibility that noncognate TFs could initiate transcription, with
potentially disastrous effects for the cell. Here, we estimate the importance
of crosstalk, suggest that its avoidance strongly constrains equilibrium models
of TF binding, and propose an alternative nonequilibrium scheme that implements
kinetic proofreading to suppress erroneous initiation. This proposal is consistent
with the observed covalent modifications of the transcriptional apparatus and
predicts increased noise in gene expression as a trade-off for improved specificity.
Using information theory, we quantify this trade-off to find when optimal proofreading
architectures are favored over their equilibrium counterparts. Such architectures
exhibit significant super-Poisson noise at low expression in steady state.'

text: We consider real symmetric and complex Hermitian random matrices with the
additional symmetry hxy = hN-y,N-x. The matrix elements are independent (up to
the fourfold symmetry) and not necessarily identically distributed. This ensemble
naturally arises as the Fourier transform of a Gaussian orthogonal ensemble. Italso
occurs as the flip matrix model - an approximation of the two-dimensional Anderson
model at small disorder. We show that the density of states converges to the Wigner
semicircle law despite the new symmetry type. We also prove the local version
of the semicircle law on the optimal scale.

text: High-throughput live-cell screens are intricate elements of systems biology
studies and drug discovery pipelines. Here, we demonstrate an optogenetics-assisted
method that avoids the need for chemical activators and reporters, reduces the
number of operational steps and increases information content in a cell-based
small-molecule screen against human protein kinases, including an orphan receptor
tyrosine kinase. This blueprint for all-optical screening can be adapted to many
drug targets and cellular processes.

text: "We present a method for simulating brittle fracture under the assumptions
of quasi-static linear elastic fracture mechanics (LEFM). Using the boundary element
method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture
surfaces. The computational cost of the BEM is alleviated by using a low-resolution
mesh and interpolating the resulting stress intensity factors when propagating
the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture
surfaces with high spatial and temporal resolution, taking spatial variation of
material toughness and/or strength into account. It also allows for crack initiation
to be handled separately from crack propagation, which is not only more reasonable
from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating
the resolution of the crack-front from the resolution of the computational mesh
increases the efficiency and therefore the amount of visual detail on the resulting
fracture surfaces. The BEM also allows us to re-use previously computed blocks
of the system matrix."
