text: "The goal of zero-shot learning is to construct a classifier that can identify
object classes for which no training examples are available. When training data
for some of the object classes is available but not for others, the name generalized
zero-shot learning is commonly used.\r\nIn a wider sense, the phrase zero-shot
is also used to describe other machine learning-based approaches that require
no training data from the problem of interest, such as zero-shot action recognition
or zero-shot machine translation."

text: We consider random n×n matrices X with independent and centered entries and
a general variance profile. We show that the spectral radius of X converges with
very high probability to the square root of the spectral radius of the variance
matrix of X when n tends to infinity. We also establish the optimal rate of convergence,
that is a new result even for general i.i.d. matrices beyond the explicitly solvable
Gaussian cases. The main ingredient is the proof of the local inhomogeneous circular
law [arXiv:1612.07776] at the spectral edge.

text: Characteristic properties of type III CRISPR-Cas systems include recognition
of target RNA and the subsequent induction of a multifaceted immune response.
This involves sequence-specific cleavage of the target RNA and production of cyclic
oligoadenylate (cOA) molecules. Here we report that an exposed seed region at
the 3′ end of the crRNA is essential for target RNA binding and cleavage, whereas
cOA production requires base pairing at the 5′ end of the crRNA. Moreover, we
uncover that the variation in the size and composition of type III complexes within
a single host results in variable seed regions. This may prevent escape by invading
genetic elements, while controlling cOA production tightly to prevent unnecessary
damage to the host. Lastly, we use these findings to develop a new diagnostic
tool, SCOPE, for the specific detection of SARS-CoV-2 from human nasal swab samples,
revealing sensitivities in the atto-molar range.

text: RNA viruses induce the formation of subcellular organelles that provide microenvironments
conducive to their replication. Here we show that replication factories of rotaviruses
represent protein‐RNA condensates that are formed via liquid–liquid phase separation
of the viroplasm‐forming proteins NSP5 and rotavirus RNA chaperone NSP2. Upon
mixing, these proteins readily form condensates at physiologically relevant low
micromolar concentrations achieved in the cytoplasm of virus‐infected cells. Early
infection stage condensates could be reversibly dissolved by 1,6‐hexanediol, as
well as propylene glycol that released rotavirus transcripts from these condensates.
During the early stages of infection, propylene glycol treatments reduced viral
replication and phosphorylation of the condensate‐forming protein NSP5. During
late infection, these condensates exhibited altered material properties and became
resistant to propylene glycol, coinciding with hyperphosphorylation of NSP5. Some
aspects of the assembly of cytoplasmic rotavirus replication factories mirror
the formation of other ribonucleoprotein granules. Such viral RNA‐rich condensates
that support replication of multi‐segmented genomes represent an attractive target
for developing novel therapeutic approaches.

text: Rotavirus genomes are distributed between 11 distinct RNA molecules, all of
which must be selectively copackaged during virus assembly. This likely occurs
through sequence-specific RNA interactions facilitated by the RNA chaperone NSP2.
Here, we report that NSP2 autoregulates its chaperone activity through its C-terminal
region (CTR) that promotes RNA–RNA interactions by limiting its helix-unwinding
activity. Unexpectedly, structural proteomics data revealed that the CTR does
not directly interact with RNA, while accelerating RNA release from NSP2. Cryo–electron
microscopy reconstructions of an NSP2–RNA complex reveal a highly conserved acidic
patch on the CTR, which is poised toward the bound RNA. Virus replication was
abrogated by charge-disrupting mutations within the acidic patch but completely
restored by charge-preserving mutations. Mechanistic similarities between NSP2
and the unrelated bacterial RNA chaperone Hfq suggest that accelerating RNA dissociation
while promoting intermolecular RNA interactions may be a widespread strategy of
RNA chaperone recycling.

text: Remdesivir is a nucleoside analog approved by the US FDA for treatment of
COVID-19. Here, we present a 3.9-Å-resolution cryo-EM reconstruction of a remdesivir-stalled
RNA-dependent RNA polymerase complex, revealing full incorporation of 3 copies
of remdesivir monophosphate (RMP) and a partially incorporated fourth RMP in the
active site. The structure reveals that RMP blocks RNA translocation after incorporation
of 3 bases following RMP, resulting in delayed chain termination, which can guide
the rational design of improved antiviral drugs.

text: We reveal the cryo-electron microscopy structure of a type IV-B CRISPR ribonucleoprotein
(RNP) complex (Csf) at 3.9-Å resolution. The complex best resembles the type III-A
CRISPR Csm effector complex, consisting of a Cas7-like (Csf2) filament intertwined
with a small subunit (Cas11) filament, but the complex lacks subunits for RNA
processing and target DNA cleavage. Surprisingly, instead of assembling around
a CRISPR-derived RNA (crRNA), the complex assembles upon heterogeneous RNA of
a regular length arranged in a pseudo-A-form configuration. These findings provide
a high-resolution glimpse into the assembly and function of enigmatic type IV
CRISPR systems, expanding our understanding of class I CRISPR-Cas system architecture,
and suggesting a function for type IV-B RNPs that may be distinct from other class
1 CRISPR-associated systems.

text: The majority of gene transcripts generated by RNA polymerase II in mammalian
genomes initiate at CpG island (CGI) promoters1,2, yet our understanding of their
regulation remains limited. This is in part due to the incomplete information
that we have on transcription factors, their DNA-binding motifs and which genomic
binding sites are functional in any given cell type3,4,5. In addition, there are
orphan motifs without known binders, such as the CGCG element, which is associated
with highly expressed genes across human tissues and enriched near the transcription
start site of a subset of CGI promoters6,7,8. Here we combine single-molecule
footprinting with interaction proteomics to identify BTG3-associated nuclear protein
(BANP) as the transcription factor that binds this element in the mouse and human
genome. We show that BANP is a strong CGI activator that controls essential metabolic
genes in pluripotent stem and terminally differentiated neuronal cells. BANP binding
is repelled by DNA methylation of its motif in vitro and in vivo, which epigenetically
restricts most binding to CGIs and accounts for differential binding at aberrantly
methylated CGI promoters in cancer cells. Upon binding to an unmethylated motif,
BANP opens chromatin and phases nucleosomes. These findings establish BANP as
a critical activator of a set of essential genes and suggest a model in which
the activity of CGI promoters relies on methylation-sensitive transcription factors
that are capable of chromatin opening.

text: Eukaryotic DNA-binding proteins operate in the context of chromatin, where
nucleosomes are the elementary building blocks. Nucleosomal DNA is wrapped around
a histone core, thereby rendering a large fraction of the DNA surface inaccessible
to DNA-binding proteins. Nevertheless, first responders in DNA repair and sequence-specific
transcription factors bind DNA target sites obstructed by chromatin. While early
studies examined protein binding to histone-free DNA, it is only now beginning
to emerge how DNA sequences are interrogated on nucleosomes. These readout strategies
range from the release of nucleosomal DNA from histones, to rotational/translation
register shifts of the DNA motif, and nucleosome-specific DNA binding modes that
differ from those observed on naked DNA. Since DNA motif engagement on nucleosomes
strongly depends on position and orientation, we argue that motif location and
nucleosome positioning co-determine protein access to DNA in transcription and
DNA repair.

text: AT2019wey (SRGA J043520.9+552226, SRGE J043523.3+552234) is a transient first
reported by the ATLAS optical survey in 2019 December. It rose to prominence upon
detection, three months later, by the Spektrum-Roentgen-Gamma (SRG) mission in
its first all-sky survey. X-ray observations reported in Yao et al. suggest that
AT2019wey is a Galactic low-mass X-ray binary (LMXB) with a black hole (BH) or
neutron star (NS) accretor. Here we present ultraviolet, optical, near-infrared,
and radio observations of this object. We show that the companion is a short-period
(P ≲ 16 hr) low-mass (<1 M⊙) star. We consider AT2019wey to be a candidate BH
system since its locations on the Lradio–LX and Lopt–LX diagrams are closer to
BH binaries than NS binaries. We demonstrate that from 2020 June to August, despite
the more than 10 times brightening at radio and X-ray wavelengths, the optical
luminosity of AT2019wey only increased by 1.3–1.4 times. We interpret the UV/optical
emission before the brightening as thermal emission from a truncated disk in a
hot accretion flow and the UV/optical emission after the brightening as reprocessing
of the X-ray emission in the outer accretion disk. AT2019wey demonstrates that
combining current wide-field optical surveys and SRG provides a way to discover
the emerging population of short-period BH LMXB systems with faint X-ray outbursts.

text: AM CVn systems are a rare type of accreting binary that consists of a white
dwarf and a helium-rich, degenerate donor star. Using the Zwicky Transient Facility
(ZTF), we searched for new AM CVn systems by focusing on blue, outbursting stars.
We first selected outbursting stars using the ZTF alerts. We cross matched the
candidates with Gaia and Pan-STARRS catalogs. The initial selection of candidates
based on the Gaia BP-RP contains 1751 unknown objects. We used the Pan-STARRS
g-r and r-i color in combination with the Gaia color to identify 59 strong AM
CVn candidates. We obtained identification spectra of 35 sources, of which 18
are high-priority candidates, and discovered nine new AM CVn systems and one magnetic
CV that shows only He-ii lines. Using the outburst recurrence time, we estimate
the orbital periods of the nine new AM CVn systems that are in the range of 29–50
minutes. We conclude that targeted follow up of blue, outbursting sources is an
efficient method to find new AM CVn systems and we plan to follow up all candidates
we identified to systematically study the population of outbursting AM CVn systems.

text: "White dwarfs represent the last stage of evolution of stars with mass less
than about eight times that of the Sun and, like other stars, are often found
in binaries1,2. If the orbital period of the binary is short enough, energy losses
from gravitational-wave radiation can shrink the orbit until the two white dwarfs
come into contact and merge3. Depending on the component masses, the merger can
lead to a supernova of type Ia or result in a massive white dwarf4. In the latter
case, the white dwarf remnant is expected to be highly magnetized5,6 because of
the strong magnetic dynamo that should arise during the merger, and be rapidly
spinning from the conservation of the orbital angular momentum7. Here we report
observations of a white dwarf, ZTF J190132.9+145808.7, that exhibits these properties,
but to an extreme: a rotation period of 6.94 minutes, a magnetic field ranging
between 600 megagauss and 900 megagauss over its surface, and a stellar radius
of \r\n kilometres, only slightly larger than the radius of the Moon. Such a small
radius implies that the star’s mass is close to the maximum white dwarf mass,
or Chandrasekhar mass. ZTF J190132.9+145808.7 is likely to be cooling through
the Urca processes (neutrino emission from electron capture on sodium) because
of the high densities reached in its core."

text: We have carried out a search for massive white dwarfs (WDs) in the direction
of young open star clusters using the Gaia DR2 database. The aim of this survey
was (1) to provide robust data for new and previously known high-mass WDs regarding
cluster membership, (2) to highlight WDs previously included in the initial final
mass relation (IFMR) that are unlikely members of their respective clusters according
to Gaia astrometry, and (3) to select an unequivocal WD sample that could then
be compared with the host clusters' turnoff masses. All promising WD candidates
in each cluster color–magnitude diagram were followed up with spectroscopy from
Gemini in order to determine whether they were indeed WDs and derive their masses,
temperatures, and ages. In order to be considered cluster members, white dwarfs
were required to (1) have proper motions and parallaxes within 2σ, 3σ, or 4σ of
those of their potential parent cluster based on how contaminated the field was
in their region of the sky, (2) have a cooling age that was less than the cluster
age, and (3) have a mass that was broadly consistent with the IFMR. A number of
WDs included in current versions of the IFMR turned out to be nonmembers, and
a number of apparent members, based on Gaia's astrometric data alone, were rejected,
as their mass and/or cooling times were incompatible with cluster membership.
In this way, we developed a highly selected IFMR sample for high-mass WDs that,
surprisingly, contained no precursor masses significantly in excess of ∼ 6 M⊙.

text: We describe an implementation of a broad-band soft X-ray polarimeter, substantially
based on previous designs. The Globe-Orbiting Soft X-ray Polarimeter (GOSoX) is
a SmallSat. As in a related mission concept the PiSoX Polarimeter, the grating
arrangement is designed optimally for the purpose of polarimetry matching the
dispersion of a spectrometer to a laterally graded multilayer (LGML). For GOSoX,
the optics are lightweight Si mirrors in a one-bounce parabolic configuration.
The instrument covers the wavelength range from 31 A to 75 A (165 - 400 eV). Upon
satellite rotation, the intensities of the dispersed spectra, after reflection
and polarizing by the LGMLs, give the three Stokes parameters needed to determine
a source's linear polarization fraction and orientation. The design can be extended
to higher energies as LGMLs are developed further. We describe the potential scientific
return and the proposed mission concept following the results of a JPL Team X
concept study.

text: We consider the problem of reliable communication over a network containing
a hidden myopic adversary who can eavesdrop on some zro links, jam some zwo links,
and do both on some zrw links. We provide the first information-theoretically
tight characterization of the optimal rate of communication possible under all
possible settings of the tuple (zro,zwo,zrw) by providing a novel coding scheme/analysis
for a subset of parameter regimes. In particular, our vanishing-error schemes
bypass the Network Singleton Bound (which requires a zero-error recovery criteria)
in a certain parameter regime where the capacity had been heretofore open. As
a direct corollary we also obtain the capacity of the corresponding problem where
information-theoretic secrecy against eavesdropping is required in addition to
reliable communication.

text: "We consider words Gi1⋯Gim involving i.i.d. complex Ginibre matrices and study
tracial expressions of their eigenvalues and singular values. We show that the
limit distribution of the squared singular values of every word of length m is
a Fuss–Catalan distribution with parameter \r\nm+1. This generalizes previous
results concerning powers of a complex Ginibre matrix and products of independent
Ginibre matrices. In addition, we find other combinatorial parameters of the word
that determine the second-order limits of the spectral statistics. For instance,
the so-called coperiod of a word characterizes the fluctuations of the eigenvalues.
We extend these results to words of general non-Hermitian matrices with i.i.d.
entries under moment-matching assumptions, band matrices, and sparse matrices.\r\nThese
results rely on the moments method and genus expansion, relating Gaussian matrix
integrals to the counting of compact orientable surfaces of a given genus. This
allows us to derive a central limit theorem for the trace of any word of complex
Ginibre matrices and their conjugate transposes, where all parameters are defined
topologically."

text: Significant advances in the synthesis and processing of colloidal nanocrystals
have given scientists and engineers access to a vast library of building blocks
with precisely defined size, shape, and composition. These materials have inspired
exciting prospects to enable bottom-up fabrication of programmable materials with
properties by design. Successfully assembling and connecting the building blocks
into superstructures in which constituent nanocrystals can purposefully interact
requires robust understanding of and control over a complex interplay of dynamic
physicochemical processes. Fluid interfaces provide an advantageous experimental
workbench to both probe and control these processes. Despite the ostensible simplicity
of fabricating nanocrystal assemblies at a fluid interface, sensitivity to processing
conditions and limited reproducibility have underscored the complexity of this
process. In situ studies have provided mechanistic insights into the competing
dynamics of key subprocesses including solvent spreading and evaporation, superlattice
formation, ligand detachment kinetics, and nanocrystal attachment. Understanding
how these subprocesses influence the complex choreography of self-assembly, structure
transformation, and oriented attachment processes presents a rich research challenge.
In this context, we present a detailed methodology for self-assembly and attachment
of lead chalcogenide nanocrystals at a liquid–gas interface as a model system
for the fabrication of mono- and multilayer cubic connected superlattices. We
discuss key experimental parameters such as the characteristics of the building
blocks and processing conditions and detailed steps from colloidal nanocrystal
injection to superlattice transfer. We hope that this Methods/Protocols paper
will provide guidance for future advances in the exciting path toward bringing
the prospect of nanocrystal-based programmable materials to fruition.

text: In this article, we study uniqueness of form extensions in a rather general
setting. The method is based on the theory of ordered Hilbert spaces and the concept
of domination of semigroups. Our main abstract result transfers uniqueness of
form extension of a dominating form to that of a dominated form. This result can
be applied to a multitude of examples including various magnetic Schrödinger forms
on graphs and on manifolds.

text: The Hunchback (Hb) transcription factor is crucial for anterior-posterior
patterning of the Drosophila embryo. The maternal hb mRNA acts as a paradigm for
translational regulation due to its repression in the posterior of the embryo.
However, little is known about the translatability of zygotically transcribed
hb mRNAs. Here, we adapt the SunTag system, developed for imaging translation
at single-mRNA resolution in tissue culture cells, to the Drosophila embryo to
study the translation dynamics of zygotic hb mRNAs. Using single-molecule imaging
in fixed and live embryos, we provide evidence for translational repression of
zygotic SunTag-hb mRNAs. Whereas the proportion of SunTag-hb mRNAs translated
is initially uniform, translation declines from the anterior over time until it
becomes restricted to a posterior band in the expression domain. We discuss how
regulated hb mRNA translation may help establish the sharp Hb expression boundary,
which is a model for precision and noise during developmental patterning. Overall,
our data show how use of the SunTag method on fixed and live embryos is a powerful
combination for elucidating spatiotemporal regulation of mRNA translation in Drosophila.
