text: An important quantity in liquid state theory is the radial distribution function
g(r). It can be calculated within the framework of classical density functional
theory in two very distinct ways. In the test-particle route, one fixes a single
fluid particle, turning it into an external potential in which the inhomogeneous
structure of the fluid is calculated by minimizing the functional. The second
route to g(r) in density functional theory employs the Ornstein–Zernike equation
and the pair direct correlation function, that can be obtained from the second
functional derivatives of the excess (over the ideal gas) free energy functional.
Since typically an approximate excess free energy functional is employed, the
test-particle route, which requires only one functional derivative, is more accurate
than the Ornstein–Zernike route. Here we study a two-dimensional core-shoulder
particle system and find that in some circumstances the results from the Ornstein–Zernike
route can be comparable in accuracy to the test-particle results for r > σ, the
core diameter. We also examine in detail the asymptotic r → ∞ decay of g(r), finding
a variety of possible decay wavelengths at different state points and state points
where there is a crossover from one wavelength to a very different one. This behavior
is a signature pointing to the rich phase behavior of the incipient solid phases.

text: The mass assembly and chemical enrichment of the first galaxies provide key
insights into their star formation histories and the earliest stellar populations
at cosmic dawn. Here we compile and utilise new, high-quality spectroscopic JWST/NIRSpec
Prism observations from the JWST archive. In particular, we extend the wavelength
coverage beyond the standard pipeline cut-off (5.3 μm) up to 5.5 μm, which enables
for the first time a detailed examination of the rest-frame optical emission-line
properties for galaxies at z ≈ 10. Crucially, the improved calibration allows
us to detect Hβ and the [O III] λλ4959, 5007 doublet and resolve the auroral [O III]
λ4363 line for the 11 galaxies in our sample (z = 9.3 − 10.0) to obtain direct
Te-based metallicity measurements. We find that the interstellar medium (ISM)
of all galaxies shows high ionisation fields and electron temperatures, with derived
metallicities in the range 12 + log(O/H) = 7.1 − 8.3 (3–50% solar), consistent
with previous strong-line diagnostics based on JWST data at high redshifts. We
derive an empirical relation for MUV and 12 + log(O/H) at z ≈ 10, useful for future
higher-redshift studies, and show that the sample galaxies are ‘typical’ star-forming
galaxies though with relatively high specific star formation rates (median sSFR
= SFRHβ/M★ = 38 Gyr−1) and with evidence of bursty star formation on 10 Myr versus
100 Myr timescales (log10(SFR10/SFR100)≈0.7). Combining the rest-frame optical
line analysis and detailed UV to optical spectro-photometric modelling, we determine
the mass-metallicity relation (MZR) and the fundamental metallicity relation (FMR)
of the sample, pushing the previous redshift frontier of these measurements to
z = 10. These results, together with literature measurements, point to a gradually
decreasing MZR at higher redshifts, with a break in the FMR at z ≈ 3, decreasing
to metallicities ≈3× lower at z = 10 than observed in galaxies during the majority
of cosmic time at z = 0 − 3, likely caused by massive pristine gas inflows diluting
the observed metal abundances during early galaxy assembly at cosmic dawn.

text: The cytoplasmic antiviral sensor MDA5 is activated by double-stranded RNAs.
Endogenous double-stranded RNAs are modified by the A-to-I RNA-editing ADAR family
to prevent activation of MDA5. In vivo, cytoplasmic ADAR1p150 is critically required
to suppress MDA5 activation, yet the editing signature of all ADAR isoforms is
strongly overlapping in mice. Further, it is not clear how A-to-I modifications
in dsRNA prevent MDA5 activation. Here we show that 3′ UTRs harboring inverted
repeats activate MDA5 in vitro and in cells. In vitro editing by either ADAR isoform
leads to editing at overlapping hotspot regions and prevents MDA5 activation in
vitro and in cells. Remarkably, only inosines introduced by RNA editing are capable
of suppressing MDA5 activation, while replacing guanosines with inosines during
in vitro transcription has no impact on MDA5 activation. A comparison of inosines
introduced by ADAR1p150 in vitro, in cells, and in vivo suggests that a small
number of A-to-I conversions may be critically required to suppress MDA5 activation.
As those critical editing events are predominantly altering A:U basepairs into
I:U wobble basepairs, we suggest that the helical distortion introduced by those
wobble pairs may prevent MDA5 polymerization and thus downstream activation of
the type I interferon response.

text: "We present a study of a pseudo little red dot with no metal lines (Pseudo-LRD-NOM),
a highly magnified lowmass galaxy behind the lensing cluster A370 at z = 5.96.
We classify this object as a pseudo-LRD because its red\r\nrest-frame optical
color is contaminated by a prominent Hα line (with EW0 ≳ 800 Å) present in its
JWST\r\nNIRSpec spectrum. Hα is dominated by a narrow component and also has a
minor broad component indicative of\r\nan active black hole with MBH ≈ 5.6 × 10^6
M⊙. A narrow Hβ emission line is also detected (where the signal-tonoise ratio,
S/N, is 8), producing a Balmer decrement (narrow) Hα/Hβ = 11. The rest-frame UV
spectral slope is ßspec/uv = - 1.20 ± 0.28. All these features can be ascribed
to high dust attenuation. However, no [O III]λ5007 or\r\nany other metal lines
are detected in the spectrum, so [O III]5007/Hβ < 0.25, at odds with a simple
dust attenuation explanation. Accounting for all the spectral properties requires
the model of a starburst with moderate\r\ncolor excess E(B − V )≈0.2–0.5, high
gas density (nH ≳ 10^6 cm^−3\r\n), and low- to extremely-low gas/stellar\r\nmetallicities
(Z = 0.01–0.1 Z⊙). The demagnified stellar mass is\r\n× 2.25+\r\n0\r\n1\r\n.\r\n.\r\n8\r\n3\r\n3\r\n0
10^7 M , and the stellar-mass surface\r\ndensity is = +\r\n* 418 M pc 310\r\n725
2, similar to that of massive/nuclear star clusters. Pseudo-LRD-NOM provides\r\nevidence
of massive black-hole growth occurring in a high-density, dusty starburst that
is at the early stages of its\r\nchemical enrichment, and is likely a precursor
to a real LRD."

text: Efficient data structures for computing the cutset of a set of nodes in a
graph undergoing dynamic edge insertions/deletions are well-studied in undirected
graphs. We study this problem in directed graphs and show a reduction from the
Online Boolean Matrix-Vector Multiplication Conjecture (OMv) introduced by Henzinger
et al. [STOC’15]. We prove conditional on OMv that a dynamic data structure computing
the directed cutset of a set of nodes cannot have an amortized time of both O(n2−ε)
for a query operation and O(n1−ε) for an update operation, for any constant ε > 0,
even when an adversary’s operations are restricted to the incremental or decremental
settings. We further give algorithms to match these lower bounds.

text: "Consider a bipartite quantum system, where Alice and Bob jointly possess\r\na
pure state |ψ\x02. Using local quantum operations on their respective subsystems,
and\r\nunlimited classical communication, Alice and Bob may be able to transform
|ψ\x02 into\r\nanother state |φ\x02. Famously, Nielsen’s theorem [28] provides
a necessary and sufficient\r\nalgebraic criterion for such a transformation to
be possible (namely, the entanglement\r\nspectrum of |φ\x02 should majorise the
entanglement spectrum of |ψ\x02). In the paper where\r\nNielsen proved this theorem,
he conjectured that in the limit of large dimensionality, for\r\nalmost all pairs
of states |ψ\x02, |φ\x02 (according to the natural unitary invariant measure)
such\r\na transformation is not possible. That is to say, typical pairs of quantum
states |ψ\x02, |φ\x02\r\nare entangled in fundamentally different ways, that cannot
be converted to each other via\r\nlocal operations and classical communication.ViaNielsen’s
theorem, this conjecture can\r\nbe equivalently stated as a conjecture about majorisation
of spectra of random matrices\r\nfrom the so-called trace-normalised complex Wishart–Laguerre
ensemble. Concretely,\r\nlet X and Y be independent n × m random matrices whose
entries are i.i.d. standard\r\ncomplex Gaussians; then Nielsen’s conjecture says
that the probability that the spectrum\r\nof XX†/ tr(XX†) majorises the spectrum
of YY†/ tr(YY†) tends to zero as both n and\r\nm grow large. We prove this conjecture,
and we also confirm some related predictions\r\nof Cunden et al. [12]."

text: 'Physical processes at play in the genesis and evolution of tropical cyclones
are conducive to the formation of warm cores at their centres. When the warm anomaly
is particularly large in the upper troposphere, it is referred to as a high-level
warm core. Previous works documented the generation of high-level warm cores as
a consequence of stratospheric air intrusion into the troposphere induced by the
upper-level dynamics of a tropical cyclone. However, little attention has been
given to their effects on the storm''s subsequent evolution. It has been suggested
that the presence of a high-level warm core can have opposite effects on tropical
cyclone intensity: both strengthening and weakening have been described as possible
consequences of its formation. In this study, we examine the role of high-level
warm cores in the intensification and dissipation processes of tropical cyclones,
as reproduced in numerical models of different complexities, namely the model
“System for Atmospheric Modeling” (SAM) run under idealized conditions and the
model Nonhydrostatic ICosahedral Atmospheric Model run under realistic conditions
following the DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic
Domains summer protocol. Our results confirm the hypothesis of a stratospheric
origin behind the formation of high-level warm cores. Their initial role is shown
to be an enhancement of storm intensity, by a lowering of the hydrostatic sea-level
pressure (HSLP) associated with the presence of warm air aloft. However, as the
warm anomaly intensifies and extends to lower levels, it also increases static
stability in the air column, with the consequence of inhibiting convection and
ultimately contributing to cyclone dissipation. These findings suggest that high-level
warm cores play a dual role in the tropical cyclone life cycle, providing a stabilizing
mechanism that can limit cyclone strength and longevity.'

text: Using deep, medium-resolution, JWST rest-optical spectra of a sample of typical
star-forming galaxies (Lyman-break galaxies and Lyman-α emitters) from the LyC22
survey at z ∼ 3, we determined the nebular abundances of N, O, and Ne relative
to H for a subsample of 25 objects with a direct method based on auroral [O III]
λ4363 line detections. Our measurements increased the number of accurate N/O determinations
at z ∼ 2 − 4 using a homogeneous approach. We found a mean value of log(N/O) =
−+0.25−0.21 over a metallicity range of 12 + log(O/H) = 7.56 to 8.44. The observed
N/O ratio and scatter are indistinguishable from that observed in low-z galaxies
and H II regions over the same metallicity range, thus showing no redshift evolution
of N/O for typical galaxies over a significant fraction of cosmic time. We also
show that typical z ∼ 3 galaxies have a similar offset in the BPT diagram to galaxies
from the low-z Lyman Continuum Survey (LzLCS) when compared to the average of
SDSS galaxies, and we demonstrate that this offset is not due to enhanced nitrogen
abundances. Our results establish a basis for future studies of the evolution
of N and O at higher redshifts.

text: Bio-inspired photonic synapses integrate optical sensing, memory, and processing
in a single platform, overcoming the bottlenecks of traditional CMOS-based vision
sensors. Most existing neuromorphic vision systems either rely on electrical inputs
for bidirectional conductance modulation, limiting their operating speed and bandwidth,
or lack nonvolatility, leading to nonlinear weight updates and poor efficiency
in image recognition tasks. Here, we report a two-terminal, fully light-controlled
synaptic memristor based on CsPbBr3/ZnO nanorod heterojunction that demonstrates
4-bit memory storage and optical logic operations within a single architecture.
The device emulates essential functions of both excitatory and inhibitory synapses,
utilizing positive photoconductivity under UV illumination (λ = 375 nm) and anomalous
negative photoconductivity under visible light (λ = 450 nm). By controlling defect
concentrations at the CsPbBr3/ZnO nanorod interface, the device exhibits nonvolatile
multibit memory with near-linear, symmetric conductance modulation, achieving
92.4% image recognition accuracy with a convolutional neural network. The bidirectional
photoresponse enables reconfigurable optical logic operations, demonstrating integrated
logic-in-memory. Additionally, when integrated on a flexible platform, the device
demonstrates stable synaptic performance under repeated mechanical bending. These
results highlight the potential of CsPbBr3/ZnO nanorod heterojunction-based all-photonic
synapses as building blocks for multibit storage, optical information processing,
and wearable neuromorphic vision systems.

text: "With probability 1, we assess the average behaviour of various arithmetic
functions at the values of degree \U0001D451 polynomials \U0001D453∈ℤ[\U0001D461]
that are ordered by height. This allows us to establish averaged versions of the
Bateman–Horn conjecture, the polynomial Chowla conjecture and to address a basic
question about the integral Hasse principle for norm form equations. Moreover,
we are able to quantify the error term in the asymptotics and the size of the
exceptional set of \U0001D453, both with arbitrary logarithmic power savings."

text: "We introduce a new primitive, called beholder signatures (Full version [14]
of the paper is available at https://eprint.iacr.org/2025/1900), which, in some
sense, are the opposite of blind signatures. In a beholder signature, one signs
a commitment to a (potentially very long) message, and the signature attests that
the parties participating in the signing process, who know the secret key, jointly
also know the entire committed message. This guarantee holds even against distributed
adversaries that use secure multi-party computation (MPC) to produce the signature.
We work in the distributed adversarial model (Dziembowski, Faust, and Lizurej,
Crypto’23), where one assumes that it is infeasible to evaluate a large number
of hash queries without any of the participating parties learning the input. We
propose a construction of beholder signatures in the random oracle model. The
starting point of our construction is proofs of complete knowledge, recently proposed
by (Kelkar et al. CCS’24), which build on Fischlin’s transformation of a sigma
protocol to a non-interactive, straight-line extractable zero-knowledge proof
of knowledge. Our scheme is concretely efficient and comes with a proof-of-concept
implementation using Schnorr as the underlying sigma protocol.\r\n\r\nThe primary
applications of beholder signatures can be found within the blockchain space.
In particular, we describe how to use them to construct proofs of custody (Feist,
2021) that do not require ephemeral keys and are non-interactive. We also outline
applications to data dissemination, data availability, and proofs of replication."

text: "Atoms and photons, two things so different but yet so alike. The former,
the building block of matter, something we learn about in school and imagine it
as some tiny marbles encircled by other tinier marbles. The latter, an electromagnetic
wave, a light particle or an excitation of the electromagnetic field. Quantum
mechanics tells us about the properties of these two entities. And even if it
sounds, looks and writes counter-intuitive, it has proven right for over a century
now.\r\n\r\nIn this work, I elaborate on how we tested the laws of quantum mechanics
and how we used them learn more about the tiny building blocks of nature and the
fields they use to talk to each other. The atoms we use, are artificial. Superconducting
qubits, small electrical circuits with quantized energy levels behave like electrons
that transition between different orbitals in an atom. One of the qubits' advantages,
is also a big disadvantage. We design the circuits' energy levels and fabricate
them in a cleanroom. This allows for arbitrary spaced energy levels but in contrast
to real atoms, prevents two superconducting qubits from being alike. Still, this
qubit platform is one of the frontrunners for future quantum computing technology
and testing fundamental physics due to their scalability.\r\n\r\nWe interface
superconducting qubits, which operate in the GHz regime, with microwave photons.
We use 3D aluminum cavities as mediators between qubits and photons. The cavities
allow for non-destructive readout of the qubit state, they shield the qubits from
noise at the qubit frequency and they give us an easy way to frequency-tune these
joint systems.\r\n\r\nWe need to operate superconducting qubits and their cavities
at millikelvin temperatures in dilution refrigerators. At higher temperatures,
superconductivity suffers and even worse, the environment is filled with thermal
noise photons. This poses a fundamental limitation on the scalability of superconducting
qubit devices. Also connecting multiple devices in different fridges does not
work over room temperature links because the microwave photons used for this purpose
will be covered in noise and the quantum information they carry, will be unusable.\r\n\r\nInfrared
photons do not suffer from this noise problem since there are close to zero thermal
noise photons at their frequencies at room temperature. We cannot simply interface
superconducting devices with optical photons due their frequency mismatch and
the destructive effect of optical photons on superconductors. Therefore, we use
microwave-to-optics transducers that allow to convert microwave photons into optical
ones and vice-versa. The transducers that we use are macroscopic electro-optic
transducers using the Pockels effect in a disk-shaped Lithium Niobate whispering
gallery mode resonator. By using a strong optical pump, photons from the two frequency
domains experience a beam-splitter interaction and get converted from one to the
other.\r\n\r\nWe measure the generated optical photons using elaborate optical
setups, optical heterodyning and single photon detectors to gain knowledge about
the qubit state or the converted microwave photons. Bridging the microwave and
the optical world allows us to take advantage of both of their strengths but it
also requires deep knowledge about both of their working principles.\r\n\r\nIn
this work, we describe two experiments that our group conducted to showcase the
opportunities that arise from interfacing superconducting qubits with optical
photons but also the pitfalls, one may encounter on the way.\r\n\r\nIn the first
experiment, we managed to all-optically read out a superconducting qubit. We show
that the assignment fidelity, the probability that a measurement of the qubit
state matches the prepared state, is close to equal for all-optical, microwave-to-optics
and conventional microwave readout. We show T1 and T2 measurements for all three
readout types and give an analysis of the noise caused by the optics. Finally,
we show that the infrared light does not affect the qubit performance in a negative
way but that the heating it causes does. This is an important insight that we
used in the next experiment.\r\n\r\nThe second experiment is the upconversion
of itinerant single microwave photons to the optical domain. We show that we can
generate single microwave photons from a qubit-cavity system. We upconvert these
single photons, measure them with a single photon detector and reconstruct their
shape. By conducting a single photon Rabi measurement, we show correlations between
the microwave and the optical domain. And by thorough signal-to-noise measurements
and noise analysis, we find that we can generate single infrared photons with
high signal-to-noise ratio 5.1 and low transducer added noise (<0.012 quanta).
We show that this measurement creates a path towards entanglement of a superconducting
qubit and an optical photon and what parameters need to be improved to achieve
it. Additionally, this experiment is a proof of principle for an on-demand infrared
single photon source. More generally, it allows to link microwave quantum technology
in general to the optical domain."

text: Superconducting qubits are a leading candidate for utility-scale quantum computing
due to their fast gate speeds and steadily decreasing error rates. The requirement
for millikelvin operating temperatures, however, creates a significant scaling
bottleneck. Modular architectures using optical fiber links could bridge separate
cryogenic nodes, but superconducting circuits do not have coherent optical transitions
and microwave-to-optical conversion has not been shown for any non-classical photon
state. In this work, we demonstrate the on-demand generation and tomographic reconstruction
of itinerant single microwave photons at 8.9 GHz from a superconducting qubit.
We upconvert this non-Gaussian state with a transducer added noise below 0.012
quanta and count the converted telecom photons at 193.4 THz with a signal-to-noise
ratio of up to 5.1$\pm$1.1. We characterize the trade-offs between throughput
and noise, and establish a viable path toward heralded entanglement distribution
and gate teleportation. Looking ahead, these results empower existing superconducting
devices to take a key role in distributed quantum technologies and heterogeneous
quantum systems.

text: The shape of animal cells is controlled by their surface, which comprises
the cell cortex, a peripheral actin network, tethered to the plasma membrane by
membrane-to-cortex attachment proteins. Changes in cortical components have long
been considered to dominate the regulation of forces and mechanical properties
at the cell surface and drive morphogenesis. Here, we show that the coupling of
the cortex to the membrane is also key for the regulation of its mechanical properties.
By combining molecular engineering with biophysical approaches and in-cell cryo-electron
tomography we describe the cell surface with nanometer-resolution and link its
organization to cell-scale mechanics. We find that membrane-to-cortex attachment
proteins can physically draw the cortex closer to the membrane, in a density and
length-dependent manner. This reduction of the membrane-to-cortex distance controls
the activity of the formin mDia1, leading to a reduction in cortical tension.
Our study thus defines a novel mechanism whereby the membrane-to-cortex distance
is a functional geometrical parameter that regulates cell surface properties.

text: Deep convection from tropical cyclones (TCs) can reach the height of the tropopause
and as such an interaction between the upper troposphere and lower stratosphere
is likely to occur. Such interactions have been reported in both numerical and
observational studies, mainly showing that subsidence from the stratosphere into
the eye of an intensifying storm leads to a high-level warm core. However, the
effect of this upper-level warming on the intensity of the TCs is not yet well
understood. In this study, we show that subsiding air from the stratosphere beyond
subsidence in the eye is the reason for the upper-level warming in idealized simulations.
We further show that it is possible to quantify the effects of the upper-level
warming on the potential intensity of the TC. Finally, we conclude that overshooting
convection into the stratosphere causes the observed subsidence, as both become
more pronounced with increasing sea-surface temperatures (SST).

text: Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider
uncertainties in transition probabilities by defining a set of possible transition
functions. An objective is a set of runs (or infinite trajectories) of the RMDP,
and the value for an objective is the maximal probability that the agent can guarantee
against the adversarial environment. We consider (a) reachability objectives,
where given a target set of states, the goal is to eventually arrive at one of
them; and (b) parity objectives, which are a canonical representation for ω-regular
objectives. The qualitative analysis problem asks whether the objective can be
ensured with probability 1. In this work, we study the qualitative problem for
reachability and parity objectives on RMDPs without making any assumption over
the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are
twofold. We first present efficient algorithms with oracle access to uncertainty
sets that solve qualitative problems of reachability and parity objectives. We
then report experimental results demonstrating the effectiveness of our oracle-based
approach on classical RMDP examples from the literature scaling up to thousands
of states.

text: 'Partially observable Markov decision processes (POMDPs) are a central model
for uncertainty in sequential decision making. The most basic objective is the
reachability objective, where a target set must be eventually visited, and the
more general parity objectives can model all omega-regular specifications. For
such objectives, the computational analysis problems are the following: (a) qualitative
analysis that asks whether the objective can be satisfied with probability 1 (almost-sure
winning) or probability arbitrarily close to 1 (limit-sure winning); and (b) quantitative
analysis that asks for the approximation of the optimal probability of satisfying
the objective. For general POMDPs, almost-sure analysis for reachability objectives
is EXPTIME-complete, but limit-sure and quantitative analyses for reachability
objectives are undecidable; almost-sure, limit-sure, and quantitative analyses
for parity objectives are all undecidable. A special class of POMDPs, called revealing
POMDPs, has been studied recently in several works, and for this subclass the
almost-sure analysis for parity objectives was shown to be EXPTIME-complete. In
this work, we show that for revealing POMDPs the limit-sure analysis for parity
objectives is EXPTIME-complete, and even the quantitative analysis for parity
objectives can be achieved in EXPTIME.'

text: We study differentially private model training with stochastic gradient descent
under learning rate scheduling and correlated noise. Although correlated noise,
in particular via matrix factorizations, has been shown to improve accuracy, prior
theoretical work focused primarily on the prefix-sum workload. That workload assumes
a constant learning rate, whereas in practice learning rate schedules are widely
used to accelerate training and improve convergence. We close this gap by deriving
general upper and lower bounds for a broad class of learning rate schedules in
both single- and multi-epoch settings. Building on these results, we propose a
learning-rate-aware factorization that achieves improvements over prefix-sum factorizations
under both MaxSE and MeanSE error metrics. Our theoretical analysis yields memory-efficient
constructions suitable for practical deployment, and experiments on CIFAR-10 and
IMDB datasets confirm that schedule-aware factorizations improve accuracy in private
training.

text: 'Differential privacy (DP) has established itself as one of the standards
for ensuring privacy of individual data. However, reasoning about DP is a challenging
and error-prone task, hence methods for formal verification and refutation of
DP properties have received significant interest in recent years. In this work,
we present a novel method for automated formal refutation of є-DP. Our method
refutes є-DP by searching for a pair of inputs together with a non-negative function
over outputs whose expected value on these two inputs differs by a significant
amount. The two inputs and the non-negative function over outputs are computed
simultaneously, by utilizing upper expectation supermartingales and lower expectation
submartingales from probabilistic program analysis, which we leverage to introduce
a sound and complete proof rule for є-DP refutation. To the best of our knowledge,
our method is the first method for є-DP refutation to offer the following four
desirable features: (1) it is fully automated, (2) it is applicable to stochastic
mechanisms with sampling instructions from both discrete and continuous distributions,
(3) it provides soundness guarantees, and (4) it provides semi-completeness guarantees.
Our experiments show that our prototype tool SuperDP achieves superior performance
compared to the state of the art and manages to refute є-DP for a number of challenging
examples collected from the literature, including ones that were out of the reach
of prior methods.'
