Accelerating Identification of Relevant Polarons in Batteries

Abstract Many of the materials under consideration as battery electrodes are known to exhibit polarons─charge carriers localized through polarizing their environments, which are unfortunately quite costly to tackle by theory. Next to costly ab initio methods and geometry optimiza...

Income sharing for common pool resources with uncertain productivity

Abstract We address the interconnected issues of externalities in the use of a natural common‐pool resource system and adverse effects of environmental uncertainty on risk‐averse resource users. We set up a simple analytical model and derive conditions such that insurance by mean...

Arithmetic properties of the Taylor coefficients of differentially algebraic power series

Let f = ∑ n = 0 ∞ f n x n ∈ ℚ ¯ 〚 x 〛 be a solution of an algebraic differential equation Q ( x , y ( x ) , ⋯ , y ( k ) ( x ) ) = 0 , where Q is a multivariate polynomial with coefficients in ℚ ¯ . The sequence ( f n ) n ≥ 0 satisfies a non-linear recurrence, whose expression i...

Can Intraoperative Therapeutic Window Data Predict Chronic Contact Selection in Deep Brain Stimulation?

Abstract Deep brain stimulation (DBS) programming relies on selecting electrode contacts that maximize clinical benefit while minimizing side effects. The therapeutic window (range of current yielding symptom improvement without adverse effects) is a key criterion in this decisio...

Opening Pandora’s box: Paper mills in conference proceedings

OBJECTIVE: Paper mills are a growing threat to the integrity of science, yet their penetration in conference proceedings remains underexplored despite conferences being more important than journals in some scientific subfields. This study aims to identify papers in conference pro...

Variance reduction for forces and pressure in variational Monte Carlo

We present simple and practical strategies to reduce the variance of Monte Carlo estimators. Our focus is on variational Monte Carlo calculations of atomic forces and pressure in electronic systems, although we show that the underlying ideas apply more broadly to other observable...

AADT: Abstract Abstract Data Types

Proving properties of programs that manipulate compound data structures requires both disjunctive reasoning (e.g., a pointer may target different arrays) and relational reasoning. Existing abstract interpreters struggle to combine both: non-relational designs support modular comp...

HySoP: Hybrid Simulation with Particles

Official release of the code.

Development of ultrafast and radiation-hard GAGG for the next-generation of High-Energy Physics calorimeters

The evolution of High Energy Physics (HEP) toward future collider experiments with High Luminosity (HL), such as the HL-LHC, requires the development of scintillating materials that combine high density, excellent radiation hardness and an ultrafast response. While Cerium-doped G...

A spatial scan statistical for categorical, functional data

We have developed and tested a spatial scan statistic for categorical, functional data (CFSS) - a data structure within which current approaches cannot identify spatial clusters. Our methodology combines an encoding scheme for categorical, functional observations with a nonparame...

A Decomposition Approach for Large Virtual Network Embedding

ABSTRACT Virtual Network Embedding (VNE) is the core combinatorial problem of Network Slicing, a 5G technology which enables telecommunication operators to propose diverse service‐dedicated virtual networks, embedded onto a common substrate network. VNE asks for a minimum‐cost ma...

Design of Small Circularly Polarized Luminescence-Active Planar-Chiral Azaboroles

Abstract We report an enantioselective approach toward new planar-chiral azaboroles bearing the [2.2]paracyclophane unit and studies of their (chir)optical properties. Fusing the planar-chiral scaffold with a B,N-heterocycle led to the formation of a set of three substances, all...

Spectacular Science with Everyday Materials: A Do-It-Yourself Luminescence Workshop for Broad Audiences

Abstract Chemistry is often perceived as distant and challenging, which can limit public interest and engagement. Hands-on demonstrations offer a way to make chemistry accessible, engaging, and visually appealing, while also enhancing participants’ perception of learning. This ar...

Competition between vacancy creation and filling in defect-engineering of hBN

Abstract Hexagonal boron nitride (hBN) has recently become the focus of intense research as a material that can host quantum emitters. It is known that such emission is related to point defects, but in order to conclusively correlate specific defects to their spectra, having cont...

Immobilization of Alginate Microbeads With Whole‐Cells Expressing Nitrilase for Continuous Nicotinic Acid Production in Chip Millireactor

ABSTRACT The biocatalytic production of nicotinic acid using nitrilases has emerged as a promising alternative to conventional chemical synthesis, offering improved selectivity and environmental sustainability. In this study, we developed a continuous‐flow millireactor system emp...

Scattering and inverse scattering for multipoint potentials at high energies

Abstract We consider the solvable Schrödinger equation with a multipoint potential of Bethe–Peierls–Thomas–Fermi type. For this singular potential, we develop scattering and inverse scattering at high energies. In particular, in this framework, our results include analogs of the...

Meromorphic differentials and twisted DR hierarchies for the Hodge CohFT

Abstract In [4], two families of classical and quantum integrable hierarchies associated to arbitrary Cohomological Field Theories (CohFTs) were introduced: the meromorphic differential and twisted double ramification hierarchies. For trivial CohFT, the authors established a conn...

B lur D riving : Investigating How Personalized Blur Techniques Impact Drivers' Performance in Virtual Reality

Distracted driving remains a major safety concern, motivating approaches that aim to reduce visual overload before attention breaks down. However, visual overload varies across individuals, making it difficult to determine appropriate interventions for each driver. We investigate...

Arrival-Time Distributions as a Probe of the Preferred Foliation in Relativistic Bohmian Mechanics

Relativistic extensions of de Broglie–Bohm theory postulate a preferred foliation of spacetime, an additional structure essential for defining simultaneous configurations on Minkowski spacetime but conventionally believed to be empirically undetectable at quantum equilibrium. In...

Intra- and inter-specific variability in benthic foraminifera modulates surface sediment reworking

Abstract Bioturbation is a key ecological process that regulates benthic ecosystem functioning, including organic matter remineralization and nutrient regeneration. Despite growing evidence that meiofauna, and benthic foraminifera in particular, contribute to sediment bioturbatio...
