Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solut...

Oxygen-Pressure-LimitedRecovery of the Hematite α-Fe2O3(0001) Surface from a Reduced Fe3O4(111)-likeLayer

Abstract The oxidation kinetics of hematite α-Fe2O3(0001) surfaces are vital for its applications in catalysis, environmental remediation, and industrial processes. Despite prior studies, the roles of temperature, oxygen partial pressure, and oxygen chemical potential in controll...

Adolescents at the crossroads: genetic associations between psychotic symptoms and antisocial traits

<title>Abstract</title> Antisocial behaviour in youth has serious consequences at individual and societal level. Adolescence is also a critical period for the emergence of prodromal psychosis symptoms. Their co-occurrence may aggravate aggression and lead to severe adverse outcom...

Anatomy and impact of a high Arctic atmospheric river driving extreme winter rain and snowfall

Abstract. Atmospheric rivers (ARs) transport concentrated fluxes of heat and moisture poleward, driving temperature and precipitation extremes. Yet, their vertical structure in the High Arctic – where small thermodynamic perturbations govern rain-snow partitioning and cryospheric...

Ginger for the treatment and prevention of migraine headaches: a systematic review and meta-analysis of randomised controlled trials

Objective To determine the efficacy of ginger (either stand-alone or as an adjunct treatment) for the treatment and management of migraine headaches. Methods We searched PubMed, Embase, CINAHL, PsycINFO, Epistemonikos and Cochrane CENTRAL from inception to 26 March 2025 which was...

Critical interloping, collaboration and entangling the ‘expert cultures’ of art, science and lived experience: Jacqueline Donachie’s artist-led research on myotonic dystrophy

The article positions artist-led research as a vital methodology for an engaged, transformative and translational medical humanities. Recent scholarship aligned with the critical visual medical humanities has drawn attention to art practices as epistemologically generative, sugge...

Hoverfly responses to looming stimuli depend on elevation and speed

Abstract An object on immediate collision course generates a rapidly expanding visual stimulus on the retina, which will typically trigger a fast reaction, such as an evasive behavior. In hoverflies, for example, visual looming stimuli may be generated if the insect is about to c...

Can a nonstandard invisible pair mimic the Michel distribution?

PHOS-UK: Open-source user interface for power-hydrogen-heat optimisation for the United Kingdom

This paper introduces PHOS-UK, an open-source graphical user interface (GUI) and optimisation-based decision-support tool for optimal planning of integrated energy infrastructure in the United Kingdom (UK), including electricity, hydrogen, heating, and CO 2 infrastructures. PHOS-...

Designing vocabulary multiple-choice tests for exploring word frequency effects in distributional semantics

The representation of word meanings by positions in a vector space is now widely used across a range of psychological models and technological applications. There exist many different approaches for creating such vectors, with Distributional Semantic Vectors (DSVs) often produced...

Stable and Active AuCu and AuPd Electrocatalysts for Platinum-Free Oxygen Reduction Reaction: Design Principles from Ligand–Strain Coupling and Gold Surface Segregation

Abstract Surface–subsurface partitioning of alloying elements affects stability, strain, and adsorption energetics in heterogeneous catalysis yet remains difficult to control. Here, we use first-principles calculations and atomistic modeling to show that AuM binary alloys (M = Cu...

Multilayer networks in finance: a systematic review

<title>Abstract</title> Stress in the global financial system propagates through multiple channels, including interbank credit and funding, overlapping portfolios, and bank–firm exposures. Multilayer networks represent these channels as interdependent layers, enabling analysis of...

Synthesisand Magnetism of Silver Chromium SelenideSpinels

Abstract Chalcogenide spinels exhibit electronic and magnetic properties that are tunable through lattice occupancy and composition. Here, we report the first synthesis of spinel-phase Ag2Cr2Se4 and AgCr2Se4 and demonstrate an oxidation-induced ferro-to-ferrimagnetic transition a...

Policies for the operation of an ambulance fleet under uncertainty based on a new preparedness metric

Two important decisions in the management of an ambulance fleet are ambulance selection decisions and ambulance reassignment decisions. Ambulance selection decisions determine what to do when an emergency call arrives (such as choosing what ambulance to dispatch to the emergency...

Resolving Hidden Stoichiometriesin Bacterial ProteasomeActivator (Bpa)-Substrate Complexes by Cryo-EM and Charge DetectionMass Spectrometry

Abstract Bacterial proteasome activator (Bpa) is a regulatory particle within the Mycobacterium tuberculosis (Mtb) proteasome system that facilitates ATP-independent substrate engagement and delivery to the 20S core particle (CP) for degradation. The best characterized Bpa substr...

Building a Physics-Aware AI Ecosystem for Solid-State Hydrogen Storage Materials

Abstract Hydrogen storage remains a central bottleneck for scalable hydrogen energy systems due to the multiscale and coupled nature of the thermodynamics, kinetics, and microstructural evolution of hydrogen storage materials (HSMs). Although artificial intelligence (AI) has acce...

MicroRNA Dysregulation in HPV-Driven Cervical Cancer: A Review of Oncoprotein-Targeted Signaling Pathways

MicroRNAs (miRNAs) have been associated with the initiation, development, and progression of various cancers, including cervical cancer. Their involvement in cervical cancer is extensively documented, as they influence critical biological pathways, including apoptosis, cell cycle...
