Constitutive natural killer cell features associated with post-treatment control of SIV infection in the pVISCONTI study

Abstract Post-treatment HIV controllers (PTC) offer a unique opportunity to uncover the determinants of durable remission after antiretroviral therapy (ART) interruption. Here, using six PTC and six post-treatment non-controllers from the pVISCONTI study in cynomolgus macaques, w...

Strategic design of methane observation networks to improve emission estimates: A case study in Africa

Abstract. Ground-based and satellite atmospheric observations are essential for reducing uncertainties in methane (CH4) emissions by atmospheric inversion, particularly in data-sparse regions such as Africa. However, adding new observation sites does not yield linear improvements...

Numerical proof-of-concept of nanofoam-based targets for proton acceleration and high-energy photon and positron generation in strong fields

A source of high-energy photons, ions, and positrons can be attained with the interaction of ultra-intense femtosecond laser pulses with advanced nanostructured targets. We present and characterise a numerical model that mimics the foam deposition process on solid substrates, as...

Cosmological constraints from the Planck cluster catalogue with DES shear profiles and Chandra observations

We present cosmological constraints from the PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations from the telescope for the mass calibration. We compute hydrostatic mass estimates for all clusters in the PS...

Indistinguishable single photons from a quantum dot in a nanopost cavity

Wavelength-tunable sources of single photons are key devices for scaling up optical quantum technologies. In this context, individual quantum dots (QDs) embedded in broadband photonic nanostructures are particularly appealing. The nanopost cavity, which is built with a segment of...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

Neutron elastic scattering at $$\varvec{30.8}$$ MeV on $$\varvec{^{\text {nat}}\textrm{Ce}}$$

Abstract Elastic scattering of fast neutrons at an incident energy of 30.8 MeV on a natural cerium target was measured during an experiment conducted at the Neutrons For Science facility at GANIL-SPIRAL2. This is the first measurement on cerium using incident neutron energy above...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set reco...

Gluon production in the color glass condensate from BCFW recursion

A bstract In the Color Glass Condensate framework, the colliding projectiles are described as classical color currents. Gluon production at leading order in the coupling is obtained from the retarded solution of the classical Yang-Mills equations, with these currents acting as so...

Power-law creep in C–S–H emerging from subdiffusive dynamics

Power-laws have long been used to describe creep in cementitious systems, from C-S-H to concrete, yet their mechanistic origin remains unclear. Diffusion, layer sliding, and permeation are often invoked as microscopic drivers of creep in C-S-H, but it is uncertain whether these r...

A framework to compare the performance of spatial disaggregation methods of statistical climate downscaling in South America

Study region Chile and South America. Study focus Climate change is simulated at a coarse scale with General Circulation Models. Impact and regional studies require downscaling to increase spatial resolution. Several downscaling methods exist, but most studies do not analyze or c...

High‐Detectivity InGaAs/GaAsP Superlattice PIN Photodetector with a Thin Absorber on GaAs substrate for 1100 nm Applications

ABSTRACT III‐V materials exhibit superior optoelectronic properties compared to conventional semiconductors, making them ideal for short‐wavelength infrared (SWIR) photodetectors. These devices are in demand for applications such as telecommunications, LiDAR, and biomedical engin...

Compartmentalization of metals for photosynthesis and nitrogen fixation in specialized cells of the filamentous cyanobacterium Anabaena sp. PCC7120

Nitrogen fixing cyanobacteria, such as Anabaena sp. PCC7120, are some of the oldest multicellular organisms. When combined nitrogen sources are scarce, this cyanobacterium compartmentalizes photosynthesis and nitrogen fixation in vegetative cells and in differentiated heterocysts...

Solving the Gross-Pitaevskii equation with quantic tensor trains: Ground states and nonlinear dynamics

We develop a tensor network framework based on the quantic tensor train (QTT) format to efficiently solve the Gross-Pitaevskii equation (GPE), which governs Bose-Einstein condensates under mean-field theory. For sufficiently regular functions, the QTT approach enables exponential...

Brick kilns across India: A temporal analysis of brick kiln distribution and technology types

Thousands of brick kilns operate across India, significantly contributing to air pollution and CO 2 emissions due to outdated practices and non-compliance with environmental standards. Regulations promoting cleaner kiln technologies have been introduced, yet detailed information...

The impact of prescriptions in phenomenological extractions of transverse momentum dependent distributions

Abstract We investigate the impact of phenomenological prescriptions in the Collins–Soper–Sterman (CSS) approach for global extractions of Transverse Momentum Distributions (TMDs). We show that fits to low-energy Drell–Yan data with different choices of $$b_*$$ <mml:math xmlns:mm...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

The postsynaptic scaffolding protein SAPAP3 shapes mitochondrial activity: the case of Huntington’s disease

Abstract Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiol...

Accelerating biomass loss from forest disturbances across Europe

Abstract Forest disturbances are rising globally due to climate change and land-use pressures, weakening the terrestrial carbon sink. However, declines in aboveground biomass from tree cover loss remain poorly quantified, limiting our understanding of the role of disturbances in...
