text: Causal representation learning aims at recovering latent causal variables
from high-dimensional observations to solve causal downstream tasks, such as predicting
the effect of new interventions or more robust classification. A plethora of methods
have been developed, each tackling carefully crafted problem settings that lead
to different types of identifiability. The folklore is that these different settings
are important, as they are often linked to different rungs of Pearl's causal hierarchy,
although not all neatly fit. Our main contribution is to show that many existing
causal representation learning approaches methodologically align the representation
to known data symmetries. Identification of the variables is guided by equivalence
classes across different "data pockets" that are not necessarily causal. This
result suggests important implications, allowing us to unify many existing approaches
in a single method that can mix and match different assumptions, including non-causal
ones, based on the invariances relevant to our application. It also significantly
benefits applicability, which we demonstrate by improving treatment effect estimation
on real-world high-dimensional ecological data. Overall, this paper clarifies
the role of causality assumptions in the discovery of causal variables and shifts
the focus to preserving data symmetries.

text: False vacuum decay—the transition from a metastable quantum state to a true
vacuum state—plays an important role in quantum field theory and non-equilibrium
phenomena such as phase transitions and dynamical metastability. The non-perturbative
nature of false vacuum decay and the limited experimental access to this process
make it challenging to study, leaving several open questions regarding how true
vacuum bubbles form, move and interact. Here we observe quantized bubble formation
in real time, a key feature of false vacuum decay dynamics, using a quantum annealer
with 5,564 superconducting flux qubits. We develop an effective model that captures
both initial bubble creation and subsequent interactions, and remains accurate
under dissipation. The annealer reveals coherent scaling laws in the driven many-body
dynamics for more than 1,000 intrinsic qubit time units. This work provides a
method for investigating false vacuum dynamics of large quantum systems in quantum
annealers.

text: When microplastics (MPs) enter water bodies, they undergo various transport
processes, including sedimentation, which can be influenced by factors such as
particle size, density, and interactions with other particles. Surface waters
contain suspended natural particles (e.g., clay and silt), which may impact MP
settling rates. Here, we investigated how the presence of suspended sediments
(SS) influenced the deposition patterns and rates of MPs in turbid waters. We
systematically analyzed the settling velocities of particles, including different
MP sizes and SS concentrations, in a plexiglass column with a camera array. For
each experimental variant, we collected data on thousands of individual MPs, strengthening
the statistical analysis of the particles’ velocities. Simultaneous measurements
of the SS flow and MPs trajectories revealed that the SS induced complex flow
patterns, with MPs spending more time in downwelling flow regions, thereby accelerating
MPs sedimentation. This effect was more pronounced when SS were aggregated. Additionally,
we found that smaller MP fragments were more affected by the fluctuations than
spheres or larger fragments. Collectively, our results provide valuable data for
future MP fate models and help to understand the sedimentation processes of MPs
in natural waters, which is crucial for assessing their environmental transport
and impact.

text: "Let f(r)(n;s,k) denote the maximum number of edges in an n-vertex r-uniform
hypergraph containing no subgraph with k edges and at most s vertices. Brown,
Erdős and Sós [New directions in the theory of graphs (Proc. Third Ann Arbor Conf.,
Univ. Michigan 1971), pp. 53--63, Academic Press 1973] conjectured that the limit
limn→∞n−2f(3)(n;k+2,k) exists for all k. The value of the limit was previously
determined for k=2 in the original paper of Brown, Erdős and Sós, for k=3 by Glock
[Bull. Lond. Math. Soc. 51 (2019) 230--236] and for k=4 by Glock, Joos, Kim, Kühn,
Lichev and Pikhurko [arXiv:2209.14177, accepted by Proc. Amer. Math. Soc.] while
Delcourt and Postle [arXiv:2210.01105, accepted by Proc. Amer. Math. Soc.] proved
the conjecture (without determining the limiting value).\r\nIn this paper, we
determine the value of the limit in the Brown-Erdős-Sós Problem for k∈{5,6,7}.
More generally, we obtain the value of limn→∞n−2f(r)(n;rk−2k+2,k) for all r≥3
and k∈{5,6,7}. In addition, by combining these new values with recent results
of Bennett, Cushman and Dudek [arXiv:2309.00182] we obtain new asymptotic values
for several generalised Ramsey numbers."

text: "The online semi-random graph process is a one-player game which starts with
the empty graph on n vertices. At every round, a player (called Builder) is presented
with a vertex v chosen uniformly at random and independently from previous rounds,
and constructs an edge of their choice that is incident to v. Inspired by recent
advances on the semi-random graph process, we define a family of generalized online
semi-random models.\r\nWe analyse a particular instance that shares similar features
with the original semi-random graph process and determine the hitting times of
the classical graph properties minimum degree k,k-connectivity, containment of
a perfect matching, a Hamiltonian cycle and an \r\nH-factor for a fixed graph
H possessing an additional tree-like property. Along the way, we derive a few
consequences of the famous Aldous-Broder algorithm that may be of independent
interest."

text: 'Alcohol consumption is an important risk factor for multiple diseases. It
is typically assessed via self-report, which is open to measurement error through
recall bias. Instead, molecular data such as blood-based DNA methylation (DNAm)
could be used to derive a more objective measure of alcohol consumption by incorporating
information from cytosine-phosphate-guanine (CpG) sites known to be linked to
the trait. Here, we explore the epigenetic architecture of self-reported weekly
units of alcohol consumption in the Generation Scotland study. We first create
a blood-based epigenetic score (EpiScore) of alcohol consumption using elastic
net penalized linear regression. We explore the effect of pre-filtering for CpG
features ahead of elastic net, as well as differential patterns by sex and by
units consumed in the last week relative to an average week. The final EpiScore
was trained on 16,717 individuals and tested in four external cohorts: the Lothian
Birth Cohorts (LBC) of 1921 and 1936, the Sister Study, and the Avon Longitudinal
Study of Parents and Children (total N across studies > 10,000). The maximum Pearson
correlation between the EpiScore and self-reported alcohol consumption within
cohort ranged from 0.41 to 0.53. In LBC1936, higher EpiScore levels had significant
associations with poorer global brain imaging metrics, whereas self-reported alcohol
consumption did not. Finally, we identified two novel CpG loci via a Bayesian
penalized regression epigenome-wide association study of alcohol consumption.
Together, these findings show how DNAm can objectively characterize patterns of
alcohol consumption that associate with brain health, unlike self-reported estimates.'

text: Aqueous two-phase systems (ATPSs), phase-separating solutions of water soluble
but mutually immiscible molecular species, offer fascinating prospects for selective
partitioning, purification, and extraction. Here, we formulate a general Brownian
dynamics based coarse-grained simulation model for an ATPS of two water soluble
but mutually immiscible polymer species. Including additional solute species into
the model is straightforward, which enables capturing the assembly and partitioning
response of, e.g., nanoparticles (NPs), additional macromolecular species, or
impurities in the ATPS. We demonstrate that the simulation model captures satisfactorily
the phase separation, partitioning, and interfacial properties of an actual ATPS
using a model ATPS in which a polymer mixture of dextran and polyethylene glycol
(PEG) phase separates, and magnetic NPs selectively partition into one of the
two polymeric phases. Phase separation and NP partitioning are characterized both
via the computational model and experimentally, under different conditions. The
simulation model captures the trends observed in the experimental system and quantitatively
links the partitioning behavior to the component species interactions. Finally,
the simulation model reveals that the ATPS interface fluctuations in systems with
magnetic NPs as a partitioned species can be controlled by the magnetic field
at length scales much smaller than those probed experimentally to date.

text: 'A complete understanding of the central stars of planetary nebulae (CSPNe)
remains elusive. Over the past several decades, time-series photometry of CSPNe
has yielded significant results including, but not limited to, discoveries of
nearly 100 binary systems, insights into pulsations and winds in young white dwarfs,
and studies of stars undergoing very late thermal pulses. We have undertaken a
systematic study of optical photometric variability of cataloged CSPNe, using
the light curves from the Zwicky Transient Facility (ZTF). By applying appropriate
variability metrics, we arrive at a list of 94 highly variable CSPN candidates.
Based on the timescales of the light-curve activity, we classify the variables
broadly into short- and long-timescale variables. In this first paper in this
series, we focus on the former, which is the majority class comprising 83 objects.
We report periods for six sources for the first time, and recover several known
periodic variables. Among the aperiodic sources, most exhibit a jitter around
a median flux with a stable amplitude, and a few show outbursts. We draw attention
to WeSb 1, which shows a different kind of variability: prominent deep and aperiodic
dips, resembling transits from a dust/debris disk. We find strong evidence for
a binary nature of WeSb 1 (possibly an F-type subgiant companion). The compactness
of the emission lines and inferred high electron densities make WeSb 1 a candidate
for either an EGB 6-type planetary nucleus, or a symbiotic system inside an evolved
planetary nebula, both of which are rare objects. To demonstrate further promise
with ZTF, we report three additional newly identified periodic sources that do
not appear in the list of highly variable sources. Finally, we also introduce
a two-dimensional metric space defined by the von Neumann statistics and Pearson
Skew and demonstrate its effectiveness in identifying unique variables of astrophysical
interest, like WeSb 1.'

text: The back-action damping of mechanical motion by electromagnetic radiation
is typically overwhelmed by internal loss channels unless demanding experimental
ingredients such as superconducting resonators, high-quality optical cavities,
or large magnetic fields are employed. Here we demonstrate the first room temperature,
cavity-free, all-electric device where back-action damping exceeds internal loss,
enabled by a mechanically compliant parallel-plate capacitor with a nanoscale
plate separation and an aspect ratio exceeding 1,000. The device has 4 orders
of magnitude lower insertion loss than a comparable commercial quartz crystal
and achieves a position imprecision rivaling optical interferometers. With the
help of a back-action isolation scheme, we observe radiative cooling of mechanical
motion by a remote cryogenic load. This work provides a technologically accessible
route to high-precision sensing, transduction, and signal processing.

text: 'Stochastic PDEs of fluctuating hydrodynamics are a powerful tool for the
description of fluctuations in many-particle systems. In this paper, we develop
and analyze a multilevel Monte Carlo (MLMC) scheme for the Dean–Kawasaki equation,
a pivotal representative of this class of SPDEs. We prove analytically and demonstrate
numerically that our MLMC scheme provides a significant reduction in computational
cost (with respect to a standard Monte Carlo method) in the simulation of the
Dean–Kawasaki equation. Specifically, we link this reduction in cost to having
a sufficiently large average particle density and show that sizeable cost reductions
can be obtained even when we have solutions with regions of low density. Numerical
simulations are provided in the two-dimensional case, confirming our theoretical
predictions. Our results are formulated entirely in terms of the law of distributions
rather than in terms of strong spatial norms: this crucially allows for MLMC speed-ups
altogether despite the Dean–Kawasaki equation being highly singular.'

text: 'Lagrangian coherent structures (LCSs) are widely recognized as playing a
significant role in turbulence dynamics since they can control the transport of
mass, momentum or heat. However, the methods used to identify these structures
are often based on ambiguous definitions and arbitrary thresholding. While LCSs
theory provides precise and frame-indifferent mathematical definitions of coherent
structures, some of the commonly used extraction algorithms employed in the literature
are still case-specific and involve user-defined parameters. In this study, we
present a new, unsupervised extraction algorithm that enables the extraction of
rotational LCSs based on Lagrangian average vorticity deviation from an arbitrary
3D velocity field. The algorithm utilizes two alternative methods for the identification
of the LCS core (ridge): an unsupervised clustering method and a streamline-based
method. In a subsequent step, the ridge curve is parametrized through a pruning
procedure of minimum spanning tree graphs. To assess the effectiveness of the
algorithm, we test it on two cases: (i) direct numerical simulations of forced
homogeneous and isotropic turbulence and (ii) three-dimensional Particle Tracking
Velocimetry experiments of a turbulent gravity current.'

text: Neuronal processing of external sensory input is shaped by internally generated
top–down information. In the neocortex, top–down projections primarily target
layer 1, which contains NDNF (neuron-derived neurotrophic factor)-expressing interneurons
and the dendrites of pyramidal cells. Here, we investigate the hypothesis that
NDNF interneurons shape cortical computations in an unconventional, layer-specific
way, by exerting presynaptic inhibition on synapses in layer 1 while leaving synapses
in deeper layers unaffected. We first confirm experimentally that in the auditory
cortex, synapses from somatostatin-expressing (SOM) onto NDNF neurons are indeed
modulated by ambient Gamma-aminobutyric acid (GABA). Shifting to a computational
model, we then show that this mechanism introduces a distinct mutual inhibition
motif between NDNF interneurons and the synaptic outputs of SOM interneurons.
This motif can control inhibition in a layer-specific way and introduces competition
between NDNF and SOM interneurons for dendritic inhibition onto pyramidal cells
on different timescales. NDNF interneurons can thereby control cortical information
flow by redistributing dendritic inhibition from fast to slow timescales and by
gating different sources of dendritic inhibition.

text: We present a novel, portable sensor platform that enables concurrent monitoring
of surface mass and charge density variations at thin biointerfaces. This platform
combines a coplanar-gated field-effect transistor (FET) architecture with grating-coupled
surface plasmon resonance (SPR), yielding an integrated disposable sensor chip
prepared by nanoimprint and maskless photolithography techniques. The sensor chip
design is suitable for scalable production and relies on reduced graphene oxide
(rGO), serving as the FET’s semiconductor material for the electronic readout,
and a metallic gate electrode surface that is corrugated with a multi-diffractive
structure for optical probing with resonantly excited surface plasmons. Together
with its integration in a compact instrumentation this results in a form factor
optimized solution for dual-mode investigations without compromising the optical
or electronic sensor performance. A poly-L-lysine (PLL) – based thin linker layer
was deployed at the sensor surface to covalently attach azide-conjugated biomolecules
by using incorporated “clickable” dibenzocyclooctyne (DBCO) moieties. Interestingly,
the dual-mode measurements allow elucidating the role of the globular nature of
the PLL chains when increasing the density of DBCO attached to their backbone,
leading to PLL folding and internalization of DBCO moieties, and thus reducing
the coupling yield for the used DNA oligomers. We envision that this platform
can be employed to studying a range of other biointerface architectures and biomolecular
interaction phenomena, which are inherently tied to mass and charge density variations.

text: Differentially private weighted prefix sum under continual observation is
a crucial component in the production-level deployment of private next-word prediction
for Gboard, which, according to Google, has over a billion users. More specifically,
Google uses a differentially private mechanism to sum weighted gradients in its
private follow-the-regularized leader algorithm. Apart from efficiency, the additive
error of the private mechanism is crucial as multiplied with the square root of
the model’s dimension d (with d ranging up to 10 trillion, for example, Switch
Transformers or M6-10T), it determines the accuracy of the learning system. So,
any improvement in leading constant matters significantly in practice. In this
paper, we show a novel connection between mechanisms for continual weighted prefix
sum and a concept in representation theory known as the group matrix introduced
in correspondence between Dedekind and Frobenius (Sitzungsber. Preuss. Akad. Wiss.
Berlin, 1897) and generalized by Schur (Journal für die reine und angewandte Mathematik,
1904). To the best of our knowledge, this is the first application of group algebra
in the analysis of differentially private algorithms. Using this connection, we
analyze a class of matrix norms known as factorization norms that give upper and
lower bounds for the additive error under general ℓp-norms of the matrix mechanism.
This allows us to give 1. the first efficient factorization that matches the best-known
non-constructive upper bound on the factorization norm by Mathias (SIAM Journal
of Matrix Analysis and Applications, 1993) for the matrix used in Google’s deployment,
and also improves on the previous best-known constructive bound of Fichtenberger,
Henzinger, and Upadhyay (ICML 2023) and Henzinger, Upadhyay, and Upadhyay (SODA
2023); thereby, partially resolving an open question in operator theory, 2. the
first upper bound on the additive error for a large class of weight functions
for weighted prefix sum problems, including the sliding window matrix (Bolot,
Fawaz, Muthukrishnan, Nikolov, and Taft (ICDT 2013). We also improve the bound
on factorizing the striped matrix used for outputting a synthetic graph that approximates
all cuts (Fichtenberger, Henzinger, and Upadhyay (ICML 2023)); 3. a general improved
upper bound on the factorization norms that depend on algebraic properties of
the weighted sum matrices and that applies to a more general class of weighting
functions than the ones considered in Henzinger, Upadhyay, and Upadhyay (SODA
2024). Using the known connection between these factorization norms and the ℓp-error
of continual weighted sum, we give an upper bound on the ℓp-error for the continual
weighted sum problem for p ≥ 2.

text: "We consider fluctuations of the largest eigenvalues of the random matrix
model A + UBU∗ where A and B are N × N deterministic Hermitian (or symmetric)
matrices and U is a Haar-distributed unitary (or orthogonal) matrix. We prove
that the largest eigenvalue weakly converges to the GUE (or GOE) Tracy–Widom distribution,
under mild assumptions on A and B to\r\nguarantee that the density of states of
the model decays as square root around\r\nthe upper edge. Our proof is based on
the comparison of the Green function\r\nalong the Dyson Brownian motion starting
from the matrix A + UBU∗ and\r\nending at time N−1/3+o(1). As a byproduct of our
proof, we also prove an\r\noptimal local law for the Dyson Brownian motion up
to the constant time\r\nscale."

text: "This work concerns asymptotical stabilisation phenomena occurring in the
moduli space of sections of certain algebraic families over a smooth projective
curve, whenever the generic fibre of the family is a smooth projective Fano variety,
or not far from being Fano.\r\n We describe the expected behaviour of the class,
in a ring of motivic integration, of the moduli space of sections of given numerical
class. Up to an adequate normalisation, it should converge, when the class of
the sections goes arbitrarily far from the boundary of the dual of the effective
cone, to an effective element given by a motivic Euler product. Such a principle
can be seen as an analogue for rational curves of the Batyrev-Manin-Peyre principle
for rational points.\r\n The central tool of this article is the property of equidistribution
of curves. We show that this notion does not depend on the choice of a model of
the generic fibre, and that equidistribution of curves holds for smooth projective
split toric varieties. As an application, we study the Batyrev-Manin-Peyre principle
for curves on a certain kind of twisted products."

text: 'The identification of the parameters of a neural network from finite samples
of input-output pairs is often referred to as the teacher-student model, and this
model has represented a popular framework for understanding training and generalization.
Even if the problem is NP-complete in the worst case, a rapidly growing literature
– after adding suitable distributional assumptions – has established finite sample
identification of two-layer networks with a number of neurons (math. formula),
D being the input dimension. For the range (math. formula) the problem becomes
harder, and truly little is known for networks parametrized by biases as well.
This paper fills the gap by providing efficient algorithms and rigorous theoretical
guarantees of finite sample identification for such wider shallow networks with
biases. Our approach is based on a two-step pipeline: first, we recover the direction
of the weights, by exploiting second order information; next, we identify the
signs by suitable algebraic evaluations, and we recover the biases by empirical
risk minimization via gradient descent. Numerical results demonstrate the effectiveness
of our approach.'

text: "We present a sample of 1956 individual stellar clumps at redshift 0.7 < z
< 10, detected with JWST/NIRCam in 476 galaxies lensed by the galaxy cluster Abell2744.
The lensed clumps present magnifications ranging between μ = 1.8 and μ = 300.
We perform simultaneous size-photometry estimates in 20 JWST/NIRCam median and
broad-band filters from 0.7 to 5 μm.\r\nSpectral energy distribution (SED) fitting
analyses enable us to recover the physical properties of the clumps. The majority
of the clumps are spatially resolved and have effective radii in the range Reff
= 10–700 pc. We restrict this first study to the 1751 post-reionization era clumps
with redshift < 5.5. We find a significant evolution of the average clump ages,
star formation rates (SFRs), SFR surface densities, and metallicity with increasing
redshift, while median stellar mass and stellar mass surface densities are similar
in the probed redshift range. We observe a strong correlation between the clump
properties and the properties of their host galaxies, with more massive galaxies
hosting more massive and older clumps. We find that clumps closer to their host
galactic centre are on average more massive, while their ages do not show clear
sign of migration. We find that clumps at cosmic noon sample the upper-mass end
of the mass function to higher masses than at z > 3, reflecting the rapid increase
towards the peak of the cosmic star formation history. We conclude that the results
achieved over the studied redshift range are in agreement with expectation of
in situ clump formation scenario from large-scale disc fragmentation. "
