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...

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...

Scaling up fabrication of thin-film nanocomposite (TFN) membranes: Methods, challenges, and applications

Abstract Thin-film nanocomposite (TFN) membranes have received significant attention because of their excellent separation performance, structural flexibility, and tunability. As the demand for high-efficiency membrane technologies in industry grows, it becomes imperative to tran...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

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...

Soft Foam Polyurethane Recycling and Foaming in Reactive Extrusion Using Partial Aminolysis and a Latent Cross-Linking Chemistry

Abstract Polyurethane (PU) foams are widely used as thermosets and yet poorly recycled due to their generally cross-linked nature and the difficulty in recovering their isolated monomers from chemical recycling processes. A mechanochemical recycling process was demonstrated in th...

AI-Assisted Modeling and Coding: The Overlooked Contribution of Generative AI to Chemistry

In the context of artificial intelligence in chemistry, the first applications that come to mind are widely discussed ones, such as building surrogate models to replace costly numerical simulations or designing new compounds. However, one area where generative AI truly stands out...

France's demographic trends up to 2050: What challenges for health and safety at work? A foresight study

Background The aging of the French population is a highly inertial process, meaning we can already draw the age pyramid of 2050 with a fairly high degree of certainty. According to the French National Institute of Statistics (Insee), the French population is expected to peak at 6...

Reduced Complexity Model Intercomparison Project phase 3: experimental protocol for coordinated constraining and evaluation of reduced-complexity models

Abstract. Reduced-Complexity Models (RCMs) are a critical tool for synthesising climate science knowledge and providing climate projections for a wide range of emissions scenarios. The Reduced-Complexity Model Intercomparison Project (RCMIP) provides a framework for the coordinat...

Carbapenemase-producing Klebsiella oxytoca complex in France (2017–2023): Molecular epidemiology integrated with virulence and biofilm phenotypes

OBJECTIVES: This study analysed a large French collection of carbapenemase-producing Klebsiella oxytoca complex (KoC) isolates (2017-2023) to map species and carbapenemase distributions and identify emerging lineages. We further investigated virulence traits to understand the epi...

Nested contextual change and the temporal compression of episodic memory

Abstract How does the structure of events influence the when and the where of life experiences in comparison to the what? We developed a novel virtual reality (VR) environment to understand how the quantity of information within nested structures influence participants’ memory fo...

Behavioral changes preceded by subthalamic nucleus activity alterations in a progressive macaque model of Parkinson’s disease

Abstract Parkinson’s disease (PD) is diagnosed after motor symptoms appear, although non-motor symptoms emerge years earlier. Following years of pharmacological treatment, high-frequency stimulation (HFS) of the subthalamic nucleus (STN), a key hub in goal-directed behaviors, can...
