text: The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap
dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength
range. These observations have opened up the possibility of attosecond metrology
in solids, which would benefit from a precise measurement of the emission times
of individual harmonics with respect to the NIR laser field. Here we show that,
when high-harmonics are detected from the input surface of a magnesium oxide crystal,
a bichromatic probing of the XUV emission shows a clear synchronization largely
consistent with a semiclassical model of electron–hole recollisions in bulk solids.
On the other hand, the bichromatic spectrogram of harmonics originating from the
exit surface of the 200 μm-thick crystal is strongly modified, indicating the
influence of laser field distortions during propagation. Our tracking of sub-cycle
electron and hole re-collisions at XUV energies is relevant to the development
of solid-state sources of attosecond pulses.

text: Attosecond chronoscopy has revealed small but measurable delays in photoionization,
characterized by the ejection of an electron on absorption of a single photon.
Ionization-delay measurements in atomic targets provide a wealth of information
about the timing of the photoelectric effect, resonances, electron correlations
and transport. However, extending this approach to molecules presents challenges,
such as identifying the correct ionization channels and the effect of the anisotropic
molecular landscape on the measured delays. Here, we measure ionization delays
from ethyl iodide around a giant dipole resonance. By using the theoretical value
for the iodine atom as a reference, we disentangle the contribution from the functional
ethyl group, which is responsible for the characteristic chemical reactivity of
a molecule. We find a substantial additional delay caused by the presence of a
functional group, which encodes the effect of the molecular potential on the departing
electron. Such information is inaccessible to the conventional approach of measuring
photoionization cross-sections. The results establish ionization-delay measurements
as a valuable tool in investigating the electronic properties of molecules.

text: This chapter presents an overview of the state of the art in attosecond time-resolved
spectroscopy. The theoretical foundations of strong-field light–matter interaction
and attosecond pulse generation are described. The enabling laser technologies
are reviewed from chirped-pulse amplification and carrier-envelope-phase stabilization
to the generation and characterization of attosecond pulses. The applications
of attosecond pulses and pulse trains in electron- or ion-imaging experiments
are presented, followed by attosecond electron spectroscopy in larger molecules.
After this, high-harmonic spectroscopy and its applications to probing charge
migration on attosecond time scales is reviewed. The rapidly evolving field of
molecular photoionization delays is discussed. Finally, the applications of attosecond
transient absorption to probing molecular dynamics are presented.

text: 'The present review addresses the technical advances and the theoretical developments
to realize and rationalize attosecond-science experiments that reveal a new dynamical
time scale (10−15-10−18 s), with a particular emphasis on molecular systems and
the implications of attosecond processes for chemical dynamics. After a brief
outline of the theoretical framework for treating non-perturbative phenomena in
Section 2, we introduce the physical mechanisms underlying high-harmonic generation
and attosecond technology. The relevant technological developments and experimental
schemes are covered in Section 3. Throughout the remainder of the chapter, we
report on selected applications in molecular attosecond physics, thereby addressing
specific phenomena mediated by purely electronic dynamics: charge localization
in molecular hydrogen, charge migration in biorelevant molecules, high-harmonic
spectroscopy, and delays in molecular photoionization.'

text: 'The Habitable Exoplanet Observatory, or HabEx, has been designed to be the
Great Observatory of the 2030s. For the first time in human history, technologies
have matured sufficiently to enable an affordable space-based telescope mission
capable of discovering and characterizing Earthlike planets orbiting nearby bright
sunlike stars in order to search for signs of habitability and biosignatures.
Such a mission can also be equipped with instrumentation that will enable broad
and exciting general astrophysics and planetary science not possible from current
or planned facilities. HabEx is a space telescope with unique imaging and multi-object
spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR.
These capabilities allow for a broad suite of compelling science that cuts across
the entire NASA astrophysics portfolio. HabEx has three primary science goals:
(1) Seek out nearby worlds and explore their habitability; (2) Map out nearby
planetary systems and understand the diversity of the worlds they contain; (3)
Enable new explorations of astrophysical systems from our own solar system to
external galaxies by extending our reach in the UV through near-IR. This Great
Observatory science will be selected through a competed GO program, and will account
for about 50% of the HabEx primary mission. The preferred HabEx architecture is
a 4m, monolithic, off-axis telescope that is diffraction-limited at 0.4 microns
and is in an L2 orbit. HabEx employs two starlight suppression systems: a coronagraph
and a starshade, each with their own dedicated instrument.'

text: A binary neutron star merger has been observed in a multi-messenger detection
of gravitational wave (GW) and electromagnetic (EM) radiation. Binary neutron
stars that merge within a Hubble time, as well as many other compact binaries,
are expected to form via common envelope evolution. Yet five decades of research
on common envelope evolution have not yet resulted in a satisfactory understanding
of the multi-spatial multi-timescale evolution for the systems that lead to compact
binaries. In this paper, we report on the first successful simulations of common
envelope ejection leading to binary neutron star formation in 3D hydrodynamics.
We simulate the dynamical inspiral phase of the interaction between a 12M⊙ red
supergiant and a 1.4M⊙ neutron star for different initial separations and initial
conditions. For all of our simulations, we find complete envelope ejection and
final orbital separations of af≈1.3-5.1R⊙ depending on the simulation and criterion,
leading to binary neutron stars that can merge within a Hubble time. We find αCE-equivalent
efficiencies of ≈0.1-2.7 depending on the simulation and criterion, but this may
be specific for these extended progenitors. We fully resolve the core of the star
to ≲0.005R⊙ and our 3D hydrodynamics simulations are informed by an adjusted 1D
analytic energy formalism and a 2D kinematics study in order to overcome the prohibitive
computational cost of simulating these systems. The framework we develop in this
paper can be used to simulate a wide variety of interactions between stars, from
stellar mergers to common envelope episodes leading to GW sources.

text: "Motivation: Recent technological advances have led to an increase in the
production and availability of single-cell data. The ability to integrate a set
of multi-technology measurements would allow the identification of biologically
or clinically meaningful observations through the unification of the perspectives
afforded by each technology. In most cases, however, profiling technologies consume
the used cells and thus pairwise correspondences between datasets are lost. Due
to the sheer size single-cell datasets can acquire, scalable algorithms that are
able to universally match single-cell measurements carried out in one cell to
its corresponding sibling in another technology are needed.\r\nResults: We propose
Single-Cell data Integration via Matching (SCIM), a scalable approach to recover
such correspondences in two or more technologies. SCIM assumes that cells share
a common (low-dimensional) underlying structure and that the underlying cell distribution
is approximately constant across technologies. It constructs a technology-invariant
latent space using an autoencoder framework with an adversarial objective. Multi-modal
datasets are integrated by pairing cells across technologies using a bipartite
matching scheme that operates on the low-dimensional latent representations. We
evaluate SCIM on a simulated cellular branching process and show that the cell-to-cell
matches derived by SCIM reflect the same pseudotime on the simulated dataset.
Moreover, we apply our method to two real-world scenarios, a melanoma tumor sample
and a human bone marrow sample, where we pair cells from a scRNA dataset to their
sibling cells in a CyTOF dataset achieving 90% and 78% cell-matching accuracy
for each one of the samples, respectively."

text: "The goal of the unsupervised learning of disentangled representations is
to\r\nseparate the independent explanatory factors of variation in the data without\r\naccess
to supervision. In this paper, we summarize the results of Locatello et\r\nal.,
2019, and focus on their implications for practitioners. We discuss the\r\ntheoretical
result showing that the unsupervised learning of disentangled\r\nrepresentations
is fundamentally impossible without inductive biases and the\r\npractical challenges
it entails. Finally, we comment on our experimental\r\nfindings, highlighting
the limitations of state-of-the-art approaches and\r\ndirections for future research."

text: "We propose a novel Stochastic Frank-Wolfe (a.k.a. conditional gradient)\r\nalgorithm
for constrained smooth finite-sum minimization with a generalized\r\nlinear prediction/structure.
This class of problems includes empirical risk\r\nminimization with sparse, low-rank,
or other structured constraints. The\r\nproposed method is simple to implement,
does not require step-size tuning, and\r\nhas a constant per-iteration cost that
is independent of the dataset size.\r\nFurthermore, as a byproduct of the method
we obtain a stochastic estimator of\r\nthe Frank-Wolfe gap that can be used as
a stopping criterion. Depending on the\r\nsetting, the proposed method matches
or improves on the best computational\r\nguarantees for Stochastic Frank-Wolfe
algorithms. Benchmarks on several\r\ndatasets highlight different regimes in which
the proposed method exhibits a\r\nfaster empirical convergence than related methods.
Finally, we provide an\r\nimplementation of all considered methods in an open-source
package."

text: "Intelligent agents should be able to learn useful representations by\r\nobserving
changes in their environment. We model such observations as pairs of\r\nnon-i.i.d.
images sharing at least one of the underlying factors of variation.\r\nFirst,
we theoretically show that only knowing how many factors have changed,\r\nbut
not which ones, is sufficient to learn disentangled representations.\r\nSecond,
we provide practical algorithms that learn disentangled representations\r\nfrom
pairs of images without requiring annotation of groups, individual\r\nfactors,
or the number of factors that have changed. Third, we perform a\r\nlarge-scale
empirical study and show that such pairs of observations are\r\nsufficient to
reliably learn disentangled representations on several benchmark\r\ndata sets.
Finally, we evaluate our learned representations and find that they\r\nare simultaneously
useful on a diverse suite of tasks, including generalization\r\nunder covariate
shifts, fairness, and abstract reasoning. Overall, our results\r\ndemonstrate
that weak supervision enables learning of useful disentangled\r\nrepresentations
in realistic scenarios."

text: "The idea behind the unsupervised learning of disentangled representations
is that real-world data is generated by a few explanatory factors of variation
which can be recovered by unsupervised learning algorithms. In this paper, we
provide a sober look at recent progress in the field and challenge some common
assumptions. We first theoretically show that the unsupervised learning of disentangled
representations is fundamentally impossible without inductive biases on both the
models and the data. Then, we train over 14000\r\n models covering most prominent
methods and evaluation metrics in a reproducible large-scale experimental study
on eight data sets. We observe that while the different methods successfully enforce
properties “encouraged” by the corresponding losses, well-disentangled models
seemingly cannot be identified without supervision. Furthermore, different evaluation
metrics do not always agree on what should be considered “disentangled” and exhibit
systematic differences in the estimation. Finally, increased disentanglement does
not seem to necessarily lead to a decreased sample complexity of learning for
downstream tasks. Our results suggest that future work on disentanglement learning
should be explicit about the role of inductive biases and (implicit) supervision,
investigate concrete benefits of enforcing disentanglement of the learned representations,
and consider a reproducible experimental setup covering several data sets."

text: "Learning object-centric representations of complex scenes is a promising
step towards enabling efficient abstract reasoning from low-level perceptual features.
Yet, most deep learning approaches learn distributed representations that do not
capture the compositional properties of natural scenes. In this paper, we present
the Slot Attention module, an architectural component that interfaces with perceptual
representations such as the output of a convolutional neural network and produces
a set of task-dependent abstract representations which we call slots. These slots
are exchangeable and can bind to any object in the input by specializing through
a competitive procedure over multiple rounds of attention. We empirically demonstrate
that Slot Attention can extract object-centric representations that enable generalization
to unseen compositions when trained on unsupervised object discovery and supervised
property prediction tasks.\r\n\r\n"

text: Cryo-electron microscopy (cryo-EM) of cellular specimens provides insights
into biological processes and structures within a native context. However, a major
challenge still lies in the efficient and reproducible preparation of adherent
cells for subsequent cryo-EM analysis. This is due to the sensitivity of many
cellular specimens to the varying seeding and culturing conditions required for
EM experiments, the often limited amount of cellular material and also the fragility
of EM grids and their substrate. Here, we present low-cost and reusable 3D printed
grid holders, designed to improve specimen preparation when culturing challenging
cellular samples directly on grids. The described grid holders increase cell culture
reproducibility and throughput, and reduce the resources required for cell culturing.
We show that grid holders can be integrated into various cryo-EM workflows, including
micro-patterning approaches to control cell seeding on grids, and for generating
samples for cryo-focused ion beam milling and cryo-electron tomography experiments.
Their adaptable design allows for the generation of specialized grid holders customized
to a large variety of applications.

text: We study the unique solution m of the Dyson equation \( -m(z)^{-1} = z\1 -
a + S[m(z)] \) on a von Neumann algebra A with the constraint Imm≥0. Here, z lies
in the complex upper half-plane, a is a self-adjoint element of A and S is a positivity-preserving
linear operator on A. We show that m is the Stieltjes transform of a compactly
supported A-valued measure on R. Under suitable assumptions, we establish that
this measure has a uniformly 1/3-Hölder continuous density with respect to the
Lebesgue measure, which is supported on finitely many intervals, called bands.
In fact, the density is analytic inside the bands with a square-root growth at
the edges and internal cubic root cusps whenever the gap between two bands vanishes.
The shape of these singularities is universal and no other singularity may occur.
We give a precise asymptotic description of m near the singular points. These
asymptotics generalize the analysis at the regular edges given in the companion
paper on the Tracy-Widom universality for the edge eigenvalue statistics for correlated
random matrices [the first author et al., Ann. Probab. 48, No. 2, 963--1001 (2020;
Zbl 1434.60017)] and they play a key role in the proof of the Pearcey universality
at the cusp for Wigner-type matrices [G. Cipolloni et al., Pure Appl. Anal. 1,
No. 4, 615--707 (2019; Zbl 07142203); the second author et al., Commun. Math.
Phys. 378, No. 2, 1203--1278 (2020; Zbl 07236118)]. We also extend the finite
dimensional band mass formula from [the first author et al., loc. cit.] to the
von Neumann algebra setting by showing that the spectral mass of the bands is
topologically rigid under deformations and we conclude that these masses are quantized
in some important cases.

text: We give the first mathematically rigorous justification of the local density
approximation in density functional theory. We provide a quantitative estimate
on the difference between the grand-canonical Levy–Lieb energy of a given density
(the lowest possible energy of all quantum states having this density) and the
integral over the uniform electron gas energy of this density. The error involves
gradient terms and justifies the use of the local density approximation in the
situation where the density is very flat on sufficiently large regions in space.

text: The assembly of a septin filament requires that homologous monomers must distinguish
between one another in establishing appropriate interfaces with their neighbors.
To understand this phenomenon at the molecular level, we present the first four
crystal structures of heterodimeric septin complexes. We describe in detail the
two distinct types of G-interface present within the octameric particles, which
must polymerize to form filaments. These are formed between SEPT2 and SEPT6 and
between SEPT7 and SEPT3, and their description permits an understanding of the
structural basis for the selectivity necessary for correct filament assembly.
By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's
postulate, which predicts the exchangeability of septins from within a subgroup.
Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent
conformational change, have been repurposed in septins to play a fundamental role
in molecular recognition. Specifically, it is switch I which holds the key to
discriminating between the two different G-interfaces. Moreover, residues which
are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing
that the correct interfaces are formed.

text: Protein abundance and localization at the plasma membrane (PM) shapes plant
development and mediates adaptation to changing environmental conditions. It is
regulated by ubiquitination, a post-translational modification crucial for the
proper sorting of endocytosed PM proteins to the vacuole for subsequent degradation.
To understand the significance and the variety of roles played by this reversible
modification, the function of ubiquitin receptors, which translate the ubiquitin
signature into a cellular response, needs to be elucidated. In this study, we
show that TOL (TOM1-like) proteins function in plants as multivalent ubiquitin
receptors, governing ubiquitinated cargo delivery to the vacuole via the conserved
Endosomal Sorting Complex Required for Transport (ESCRT) pathway. TOL2 and TOL6
interact with components of the ESCRT machinery and bind to K63-linked ubiquitin
via two tandemly arranged conserved ubiquitin-binding domains. Mutation of these
domains results not only in a loss of ubiquitin binding but also altered localization,
abolishing TOL6 ubiquitin receptor activity. Function and localization of TOL6
is itself regulated by ubiquitination, whereby TOL6 ubiquitination potentially
modulates degradation of PM-localized cargoes, assisting in the fine-tuning of
the delicate interplay between protein recycling and downregulation. Taken together,
our findings demonstrate the function and regulation of a ubiquitin receptor that
mediates vacuolar degradation of PM proteins in higher plants.

text: Markov decision processes (MDPs) are the defacto framework for sequential
decision making in the presence of stochastic uncertainty. A classical optimization
criterion for MDPs is to maximize the expected discounted-sum payoff, which ignores
low probability catastrophic events with highly negative impact on the system.
On the other hand, risk-averse policies require the probability of undesirable
events to be below a given threshold, but they do not account for optimization
of the expected payoff. We consider MDPs with discounted-sum payoff with failure
states which represent catastrophic outcomes. The objective of risk-constrained
planning is to maximize the expected discounted-sum payoff among risk-averse policies
that ensure the probability to encounter a failure state is below a desired threshold.
Our main contribution is an efficient risk-constrained planning algorithm that
combines UCT-like search with a predictor learned through interaction with the
MDP (in the style of AlphaZero) and with a risk-constrained action selection via
linear programming. We demonstrate the effectiveness of our approach with experiments
on classical MDPs from the literature, including benchmarks with an order of 106
states.

text: Vaccinia virus–related kinase (VRK) is an evolutionarily conserved nuclear
protein kinase. VRK-1, the single Caenorhabditis elegans VRK ortholog, functions
in cell division and germline proliferation. However, the role of VRK-1 in postmitotic
cells and adult life span remains unknown. Here, we show that VRK-1 increases
organismal longevity by activating the cellular energy sensor, AMP-activated protein
kinase (AMPK), via direct phosphorylation. We found that overexpression of vrk-1
in the soma of adult C. elegans increased life span and, conversely, inhibition
of vrk-1 decreased life span. In addition, vrk-1 was required for longevity conferred
by mutations that inhibit C. elegans mitochondrial respiration, which requires
AMPK. VRK-1 directly phosphorylated and up-regulated AMPK in both C. elegans and
cultured human cells. Thus, our data show that the somatic nuclear kinase, VRK-1,
promotes longevity through AMPK activation, and this function appears to be conserved
between C. elegans and humans.

text: "In this paper we present a room temperature radiometer that can eliminate
the need of using cryostats in satellite payload reducing its weight and improving
reliability. The proposed radiometer is based on an electro-optic upconverter
that boosts up microwave photons energy by upconverting them into an optical domain
what makes them immune to thermal noise even if operating at room temperature.
The converter uses a high-quality factor whispering gallery\r\nmode (WGM) resonator
providing naturally narrow bandwidth and therefore might be useful for applications
like microwave hyperspectral sensing. The upconversion process is explained by\r\nproviding
essential information about photon conversion efficiency and sensitivity. To prove
the concept, we describe an experiment which shows state-of-the-art photon conversion
efficiency n=10-5 per mW of pump power at the frequency of 80 GHz."
