text: In this chapter we first review the Levy–Lieb functional, which gives the
lowest kinetic and interaction energy that can be reached with all possible quantum
states having a given density. We discuss two possible convex generalizations
of this functional, corresponding to using mixed canonical and grand-canonical
states, respectively. We present some recent works about the local density approximation,
in which the functionals get replaced by purely local functionals constructed
using the uniform electron gas energy per unit volume. We then review the known
upper and lower bounds on the Levy–Lieb functionals. We start with the kinetic
energy alone, then turn to the classical interaction alone, before we are able
to put everything together. A later section is devoted to the Hohenberg–Kohn theorem
and the role of many-body unique continuation in its proof.

text: "Traditional top-down approaches for global health have historically failed
to achieve social progress (Hoffman et al., 2015; Hoffman & Røttingen, 2015).
Recently, however, a more holistic, multi-level approach termed One Health (OH)
(Osterhaus et al., 2020) is being adopted. Several sets of challenges have been
identified for the implementation of OH (dos S. Ribeiro et al., 2019), including
policy and funding, education and training, and multi-actor, multi-domain, and
multi-level collaborations. These exist despite the increasing accessibility to\r\nknowledge
and digital collaborative research tools through the internet. To address some
of these challenges, we propose a general framework for grassroots community-based
means of participatory research. Additionally, we present a specific roadmap to
create a Machine Learning for Global Health community in Africa. The proposed
framework aims to enable any small group of individuals with scarce resources
to build and sustain an online community within approximately two years. We provide
a discussion on the potential impact of the proposed framework for global health
research collaborations."

text: "Lincheck is a new practical and user-friendly framework for testing concurrent
data structures on the Java Virtual Machine (JVM). It provides a simple and declarative
way to write concurrent tests. Instead of describing how to perform the test,
users specify what to test by declaring all the operations to examine; the framework
automatically handles the rest. As a result, tests written with Lincheck are concise
and easy to understand. \r\nThe artifact presents a collection of Lincheck tests
that discover new bugs in popular libraries and implementations from the concurrency
literature -- they are listed in Table 1, Section 3. To evaluate the performance
of Lincheck analysis, the collection of tests also includes those which check
correct data structures and, thus, always succeed. Similarly to Table 2, Section
3, the experiments demonstrate the reasonable time to perform a test. Finally,
Lincheck provides user-friendly output with an easy-to-follow trace to reproduce
a detected error, significantly simplifying further investigation."

text: Reinforcement learning has shown promising results in learning neural network
policies for complicated control tasks. However, the lack of formal guarantees
about the behavior of such policies remains an impediment to their deployment.
We propose a novel method for learning a composition of neural network policies
in stochastic environments, along with a formal certificate which guarantees that
a specification over the policy's behavior is satisfied with the desired probability.
Unlike prior work on verifiable RL, our approach leverages the compositional nature
of logical specifications provided in SpectRL, to learn over graphs of probabilistic
reach-avoid specifications. The formal guarantees are provided by learning neural
network policies together with reach-avoid supermartingales (RASM) for the graph’s
sub-tasks and then composing them into a global policy. We also derive a tighter
lower bound compared to previous work on the probability of reach-avoidance implied
by a RASM, which is required to find a compositional policy with an acceptable
probabilistic threshold for complex tasks with multiple edge policies. We implement
a prototype of our approach and evaluate it on a Stochastic Nine Rooms environment.

text: 'A crucial property for achieving secure, trustworthy and interpretable deep
learning systems is their robustness: small changes to a system''s inputs should
not result in large changes to its outputs. Mathematically, this means one strives
for networks with a small Lipschitz constant. Several recent works have focused
on how to construct such Lipschitz networks, typically by imposing constraints
on the weight matrices. In this work, we study an orthogonal aspect, namely the
role of the activation function. We show that commonly used activation functions,
such as MaxMin, as well as all piece-wise linear ones with two segments unnecessarily
restrict the class of representable functions, even in the simplest one-dimensional
setting. We furthermore introduce the new N-activation function that is provably
more expressive than currently popular activation functions. We provide code at
this https URL.'

text: The hydrogen-rich outer layers of massive stars can be removed by interactions
with a binary companion. Theoretical models predict that this stripping produces
a population of hot helium stars of ~2 to 8 solar masses (M☉), however, only one
such system has been identified thus far. We used ultraviolet photometry to identify
potential stripped helium stars then investigated 25 of them using optical spectroscopy.
We identified stars with high temperatures (~60,000 to 100,000 kelvin), high surface
gravities, and hydrogen-depleted surfaces; 16 stars also showed binary motion.
These properties match expectations for stars with initial masses of 8 to 25 M☉
that were stripped by binary interaction. Their masses fall in the gap between
subdwarf helium stars and Wolf-Rayet stars. We propose that these stars could
be progenitors of stripped-envelope supernovae.

text: Type I CRISPR-Cas systems employ multi-subunit Cascade effector complexes
to target foreign nucleic acids for destruction. Here, we present structures of
D. vulgaris type I-C Cascade at various stages of double-stranded (ds)DNA target
capture, revealing mechanisms that underpin PAM recognition and Cascade allosteric
activation. We uncover an interesting mechanism of non-target strand (NTS) DNA
stabilization via stacking interactions with the “belly” subunits, securing the
NTS in place. This “molecular seatbelt” mechanism facilitates efficient R-loop
formation and prevents dsDNA reannealing. Additionally, we provide structural
insights into how two anti-CRISPR (Acr) proteins utilize distinct strategies to
achieve a shared mechanism of type I-C Cascade inhibition by blocking PAM scanning.
These observations form a structural basis for directional R-loop formation and
reveal how different Acr proteins have converged upon common molecular mechanisms
to efficiently shut down CRISPR immunity.

text: Cas12a2 is a CRISPR-associated nuclease that performs RNA-guided, sequence-nonspecific
degradation of single-stranded RNA, single-stranded DNA and double-stranded DNA
following recognition of a complementary RNA target, culminating in abortive infection1.
Here we report structures of Cas12a2 in binary, ternary and quaternary complexes
to reveal a complete activation pathway. Our structures reveal that Cas12a2 is
autoinhibited until binding a cognate RNA target, which exposes the RuvC active
site within a large, positively charged cleft. Double-stranded DNA substrates
are captured through duplex distortion and local melting, stabilized by pairs
of ‘aromatic clamp’ residues that are crucial for double-stranded DNA degradation
and in vivo immune system function. Our work provides a structural basis for this
mechanism of abortive infection to achieve population-level immunity, which can
be leveraged to create rational mutants that degrade a spectrum of collateral
substrates.

text: 'The basic helix–loop–helix (bHLH) family of transcription factors recognizes
DNA motifs known as E-boxes (CANNTG) and includes 108 members1.
Here we investigate how chromatinized E-boxes are engaged by two structurally
diverse bHLH proteins: the proto-oncogene MYC-MAX and the circadian transcription
factor CLOCK-BMAL1 (refs. 2,3). Both transcription factors
bind to E-boxes preferentially near the nucleosomal entry–exit sites. Structural
studies with engineered or native nucleosome sequences show that MYC-MAX or CLOCK-BMAL1
triggers the release of DNA from histones to gain access. Atop the H2A–H2B acidic
patch4, the CLOCK-BMAL1 Per-Arnt-Sim (PAS) dimerization domains
engage the histone octamer disc. Binding of tandem E-boxes5–7
at endogenous DNA sequences occurs through direct interactions between two CLOCK-BMAL1
protomers and histones and is important for circadian cycling. At internal E-boxes,
the MYC-MAX leucine zipper can also interact with histones H2B and H3, and its
binding is indirectly enhanced by OCT4 elsewhere on the nucleosome. The nucleosomal
E-box position and the type of bHLH dimerization domain jointly determine the
histone contact, the affinity and the degree of competition and cooperativity
with other nucleosome-bound factors.'

text: The genomic binding sites of the transcription factor (TF) and tumor suppressor
p53 are unusually diverse with regard to their chromatin features, including histone
modifications, raising the possibility that the local chromatin environment can
contextualize p53 regulation. Here, we show that epigenetic characteristics of
closed chromatin, such as DNA methylation, do not influence the binding of p53
across the genome. Instead, the ability of p53 to open chromatin and activate
its target genes is locally restricted by its cofactor Trim24. Trim24 binds to
both p53 and unmethylated histone 3 lysine 4 (H3K4), thereby preferentially localizing
to those p53 sites that reside in closed chromatin, whereas it is deterred from
accessible chromatin by H3K4 methylation. The presence of Trim24 increases cell
viability upon stress and enables p53 to affect gene expression as a function
of the local chromatin state. These findings link H3K4 methylation to p53 function
and illustrate how specificity in chromatin can be achieved, not by TF-intrinsic
sensitivity to histone modifications, but by employing chromatin-sensitive cofactors
that locally modulate TF function.

text: 'We show that the number of linear spaces on a set of n points and the number
of rank-3 matroids on a ground set of size n are both of the form (cn+o(n))n2/6,
where c=e3√/2−3(1+3–√)/2. This is the final piece of the puzzle for enumerating
fixed-rank matroids at this level of accuracy: the numbers of rank-1 and rank-2
matroids on a ground set of size n have exact representations in terms of well-known
combinatorial functions, and it was recently proved by van der Hofstad, Pendavingh,
and van der Pol that for constant r≥4 there are (e1−rn+o(n))nr−1/r! rank-r matroids
on a ground set of size n. In our proof, we introduce a new approach for bounding
the number of clique decompositions of a complete graph, using quasirandomness
instead of the so-called entropy method that is common in this area.'

text: We report on IXPE, NICER, and XMM–Newton observations of the magnetar 1E 2259+586.
We find that the source is significantly polarized at about or above 20 per cent
for all phases except for the secondary peak where it is more weakly polarized.
The polarization degree is strongest during the primary minimum which is also
the phase where an absorption feature has been identified previously. The polarization
angle of the photons are consistent with a rotating vector model with a mode switch
between the primary minimum and the rest of the rotation of the neutron star.
We propose a scenario in which the emission at the source is weakly polarized
(as in a condensed surface) and, as the radiation passes through a plasma arch,
resonant cyclotron scattering off of protons produces the observed polarized radiation.
This confirms the magnetar nature of the source with a surface field greater than
about 1015 G.

text: We searched the Gaia DR3 database for ultramassive white dwarfs with kinematics
consistent with having escaped the nearby Hyades open cluster, identifying three
such candidates. Two of these candidates have masses estimated from Gaia photometry
of approximately 1.1 solar masses; their status as products of single-stellar
evolution that have escaped the cluster was deemed too questionable for immediate
follow-up analysis. The remaining candidate has an expected mass >1.3 solar masses,
significantly reducing the probability of it being an interloper. Analysis of
follow-up Gemini GMOS spectroscopy for this source reveals a nonmagnetized hydrogen
atmosphere white dwarf with a mass and age consistent with having formed from
a single star. Assuming a single-stellar-evolution formation channel, we estimate
a 97.8% chance that the candidate is a true escapee from the Hyades. With a determined
mass of 1.317 solar masses, this is potentially the most massive known single-evolution
white dwarf and is by far the most massive with a strong association with an open
cluster.

text: We report on Imaging X-ray polarimetry explorer (IXPE) observations of the
Be-transient X-ray pulsar LS V +44 17/RX J0440.9+4431 made at two luminosity levels
during the giant outburst in January–February 2023. Considering the observed spectral
variability and changes in the pulse profiles, the source was likely caught in
supercritical and subcritical states with significantly different emission-region
geometry, associated with the presence of accretion columns and hot spots, respectively.
We focus here on the pulse-phase-resolved polarimetric analysis and find that
the observed dependencies of the polarization degree and polarization angle (PA)
on the pulse phase are indeed drastically different for the two observations.
The observed differences, if interpreted within the framework of the rotating
vector model (RVM), imply dramatic variations in the spin axis inclination, the
position angle, and the magnetic colatitude by tens of degrees within the space
of just a few days. We suggest that the apparent changes in the observed PA phase
dependence are predominantly related to the presence of an unpulsed polarized
component in addition to the polarized radiation associated with the pulsar itself.
We then show that the observed PA phase dependence in both observations can be
explained with a single set of RVM parameters defining the pulsar’s geometry.
We also suggest that the additional polarized component is likely produced by
scattering of the pulsar radiation in the equatorial disk wind.

text: "AM Canum Venaticorum (AM CVn) systems are ultracompact binaries where a white
dwarf accretes from a helium-rich degenerate or semidegenerate donor. Some AM
CVn systems will be among the loudest sources of gravitational waves for the upcoming
Laser Interferometer Space Antenna; yet the formation channel of AM CVns remains
uncertain. We report the study and characterization of a new eclipsing AM CVn,
SRGeJ045359.9+622444 (hereafter, SRGeJ0453), discovered from a joint Spektrum-Roentgen-Gamma
(SRG) Extended Roentgen Survey with an Imaging Telescope Array (eROSITA) mission
and Zwicky Transient Facility program to identify cataclysmic variables (CVs).
We obtained optical photometry to confirm the eclipse of SRGeJ0453 and determine
the orbital period to be \r\n. We constrain the binary parameters by modeling
the high-speed photometry and radial-velocity curves and find Mdonor = 0.044 ±
0.024M⊙ and Rdonor = 0.078 ± 0.012R⊙. The X-ray spectrum is approximated by a
power-law model with an unusually flat photon index of Γ ∼ 1 previously seen in
magnetic CVs with SRG/eROSITA, but verifying that the magnetic nature of SRGeJ0453
requires further investigation. Optical spectroscopy suggests that the donor star
of SRGeJ0453 could have initially been a He star or a He white dwarf. SRGeJ0453
is the ninth eclipsing AM CVn system published to date, and its lack of optical
outbursts have made it elusive in previous surveys. The discovery of SRGeJ0453
using joint X-ray and optical surveys highlights the potential for discovering
similar systems in the near future."
