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: 'Rotations are found in physics problems at all scales: from spatial motion
of celestial bodies, to transitions between quantum states of atoms and molecules.
Mathematically, they represent a fundamental class of transformations and symmetries.
Unlike spatial displacements, rotational transformations in three-dimensional
space are non-commutative: the result of applying a sequence of rotations depends
on the order of these operations. This feature makes the emergent physics that
involves rotations rather intricate, but instrumental for studies of highly-interconnected
many-body systems. In the presence of an environment, rotational properties of
an object change, due to the interaction with particles of the environment. Owing
to the complexity of this interaction, it can be engineered to exhibit certain
properties of interest. In this Thesis, we examine several scenarios of how the
rotational behavior of an impurity can be modified by interactions with its environment.'

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."

of the Grothendieck motive of the moduli space of morphisms from an arbitrary

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. "

text: Modern experimental methods enable the creation of self-assembly building
blocks with tunable interactions, but optimally exploiting this tunability for
the self-assembly of desired structures remains an important challenge. Many studies
of this inverse problem start with the so-called fully addressable limit, where
every particle in a target structure is different. This leads to clear design
principles that often result in high assembly yield, but it is not a scalable
approach—at some point, one must grapple with “reusing” building blocks, which
lowers the degree of addressability and may cause a multitude of off-target structures
to form, complicating the design process. Here, we solve a key obstacle preventing
robust inverse design in the “semiaddressable regime” by developing a highly efficient
algorithm that enumerates all structures that can be formed from a given set of
building blocks. By combining this with established partition-function-based yield
calculations, we show that it is almost always possible to find economical semiaddressable
designs where the entropic gain from reusing building blocks outweighs the presence
of off-target structures and even increases the yield of the target. Thus, not
only does our enumeration algorithm enable robust and scalable inverse design
in the semiaddressable regime, our results demonstrate that it is possible to
operate in this regime while maintaining the level of control often associated
with full addressability.

text: Whether or not the neuron emits a spike in response to stimulation by an excitatory
current pulse is determined by a strength-duration curve (SDC) for the pulse parameters.
The SDC is a dependence of the minimal pulse amplitude required to elicit the
spiking response on either the pulse duration or its decay time. Excitatory neurons
affect the others through pulses of excitatory postsynaptic current. A simple
yet plausible approximation for the time course of such a pulse is the alpha function,
with linear rise at the start and exponential decay at the end. However, an exact
analytical SDC for this case is hitherto not known, even for the leaky integrate-and-fire
(LIF) neuron, the simplest spiking neuron model used in practice. We have obtained
general SDC equations for the LIF neuron. Using the Lambert W function — a widely-implemented
special function, we have found the exact analytical SDC for the spiking response
of the LIF neuron stimulated by an excitatory current pulse in the form of the
alpha function. To compare results in a unified way, we have also derived the
analytical SDCs for (i) rectangular pulse, (ii) ascending ramp pulse, and (iii)
instantly rising and exponentially decaying pulse. In the limit of no leakage,
we show that the SDC is reduced to the classical hyperbola for all considered
cases.

text: "Context. The hydrogen Lyman-alpha (Lyα) line, the brightest rest-frame ultraviolet
line of high-redshift galaxies, exhibits a large variety of shapes, which is due
to factors at different scales, from the interstellar medium to the intergalactic
medium (IGM).\r\nAims. The aim of this work is to provide a systematic inventory
and classification of the spectral shapes of Lyα emission lines to better understand
the general population of high-redshift Lyα emitting galaxies (LAEs).\r\nMethods.
Using the unprecedentedly deep data from the MUSE eXtremely Deep Field (MXDF;
up to 140 hour exposure time), we selected 477 galaxies observed in the ∼2.8−6.6
redshift range, 15 of which have a systemic redshift from nebular lines. We developed
a method to classify Lyα emission lines in four spectral and three spatial categories
by combining a pure spectral analysis with a narrow-band image analysis. We measured
spectral properties, such as the peak separation and the blue-to-total flux ratio
for the double-peaked galaxies.\r\nResults. To ensure a robust sample for statistical
analysis, we define two unbiased subsets, inclusive and restrictive, by applying
thresholds for signal-to-noise ratio, peak separation, and Lyα luminosity, yielding
a final unbiased sample of 206 galaxies. Our analysis reveals that between 32%
and 51% of the galaxies exhibit double-peaked profiles, with peak separations
ranging from 150 km s−1 to nearly 1600 km s−1. The fraction of double-peaked galaxies
seems to evolve dependently with the Lyα luminosity, while we do not see a severe
decrease in this fraction with redshift, which is expected given the IGM attenuation
at high redshift. An artificial increase in the number of double-peaked galaxies
at the highest redshifts may cause the observation of a plateau instead of a decrease.
A notable number of these double-peaked profiles show blue-dominated spectra,
suggesting unique gas dynamics and inflow characteristics in some high-redshift
galaxies. The consequent fraction of blue-dominated spectra needs to be confirmed
by obtaining new systemic redshift measurements. Among the double-peaked galaxies,
4% are spurious detections, that is, the blue and red peaks do not come from the
same spatial location. Around 20% out of the 477 sources of the parent sample
lie in a complex environment, meaning there are other clumps or galaxies at the
same redshift within a distance of 30 kpc.\r\nConclusions. Our results suggest
that the double-peaked LAE fraction may trace the evolution of IGM attenuation,
but the faintest galaxies must be observed at high redshift. We also need more
data to confirm the trend seen at low redshift. In addition, it is crucial to
obtain secure systemic redshifts for LAEs to better constrain the nature of the
Lyα double-peaked lines. Statistical samples of double-peaked and triple-peaked
galaxies are a promising probe of the evolution of the physical properties of
galaxies across cosmic time."

text: "Context. Recent observations suggest a significant and rapid buildup of dust
in galaxies at high redshift (z > 4); this presents new challenges to our understanding
of galaxy formation in the early Universe. Although our understanding of the physics
of dust production and destruction in a galaxy’s interstellar medium (ISM) is
improving, investigating the baryonic processes in the early universe remains
a complex task owing to the inherent degeneracies in cosmological simulations
and chemical evolution models.\r\nAims. In this work we characterized the evolution
of 98 z ∼ 5 star-forming galaxies observed as part of the ALMA Large Program ALPINE
by constraining the physical processes underpinning the gas and dust production,
consumption, and destruction in their ISM.\r\nMethods. We made use of chemical
evolution models to simultaneously reproduce the observed dust and gas content
of our galaxies, obtained respectively from spectral energy distribution (SED)
fitting and ionized carbon measurements. For each galaxy we constrained the initial
gas mass, gas inflows and outflows, and efficiencies of dust growth and destruction.
We tested these models with both the canonical Chabrier and a top-heavy initial
mass function (IMF); the latter allowed rapid dust production on shorter timescales.\r\nResults.
We successfully reproduced the gas and dust content in most of the older galaxies
(≳600 Myr) regardless of the assumed IMF, predicting dust production primarily
through Type II supernovae (SNe) and no dust growth in the ISM, as well as moderate
inflow of primordial gas. In the case of intermediate-age galaxies (300−600 Myr),
we reproduced the gas and dust content through Type II SNe and dust growth in
ISM, though we observed an overprediction of dust mass in older galaxies, potentially
indicating an unaccounted dust destruction mechanism and/or an overestimation
of the observed dust masses. The number of young galaxies (≲300 Myr) reproduced,
increases for models assuming top-heavy IMF but with maximal prescriptions of
dust production. Galactic outflows are required (up to a mass-loading factor of
2) to reproduce the observed gas and dust mass, and to recover the decreasing
trend of gas and dust over stellar mass with age. Assuming the Chabrier IMF, models
are able to reproduce ∼65% of the total sample, while with top-heavy IMF the fraction
increases to ∼93%, alleviating the tension between the observations and the models.
Observations from the James Webb Space Telescope (JWST) will allow us to remove
degeneracies in the diverse intrinsic properties of these galaxies (e.g., star
formation histories and metallicity), thereby refining our models."

text: "An action of a complex reductive group G on a smooth projective variety X
is regular when all regular unipotent elements in G act with finitely many fixed
points. Then the complex G\r\n-equivariant cohomology ring of X is isomorphic
to the coordinate ring of a certain regular fixed point scheme. Examples include
partial flag varieties, smooth Schubert varieties and Bott-Samelson varieties.
We also show that a more general version of the fixed point scheme allows a generalisation
to GKM spaces, such as toric varieties."

text: Pathogenic fungal and bacterial cells are enveloped within a cell wall, a
molecular barrier at their cell surface, and a critical architecture that constantly
evolves during pathogenesis. Understanding the molecular composition, structural
organization, and mobility of polysaccharides constituting this cell envelope
is crucial to correlate cell wall organization with its role in pathogenicity
and to identify potential antifungal targets. For the fungal pathogen Cryptococcus
neoformans, the characterization of the cell envelope has been complexified by
the presence of an additional external polysaccharide capsular shell. Here, we
investigate how magic-angle spinning (MAS) solid-state NMR techniques increase
the analytical capabilities to characterize the structure and dynamics of this
encapsulated pathogen. The versatility of proton detection experiments, dynamic-based
filters, and relaxation measurements facilitate the discrimination of the highly
mobile external capsular structure from the internal rigid cell wall of C. neoformans.
In addition, we report the in situ detection of triglyceride molecules from lipid
droplets based on NMR dynamic filters. Together, we demonstrate a nondestructive
technique to study the cell wall architecture of encapsulated microbes using C.
neoformans as a model, an airborne opportunistic fungal pathogen that infects
mainly immunocompromised but also competent hosts.

text: The rapid development of superconducting quantum hardware is expected to run
into substantial restrictions on scalability because error correction in a cryogenic
environment has stringent input–output requirements. Classical data centres rely
on fibre-optic interconnects to remove similar networking bottlenecks. In the
same spirit, ultracold electro-optic links have been proposed and used to generate
qubit control signals, or to replace cryogenic readout electronics. So far, these
approaches have suffered from either low efficiency, low bandwidth or additional
noise. Here we realize radio-over-fibre qubit readout at millikelvin temperatures.
We use one device to simultaneously perform upconversion and downconversion between
microwave and optical frequencies and so do not require any active or passive
cryogenic microwave equipment. We demonstrate all-optical single-shot readout
in a circulator-free readout scheme. Importantly, we do not observe any direct
radiation impact on the qubit state, despite the absence of shielding elements.
This compatibility between superconducting circuits and telecom-wavelength light
is not only a prerequisite to establish modular quantum networks, but it is also
relevant for multiplexed readout of superconducting photon detectors and classical
superconducting logic.
