Integrating Remote Sensing and Indigenous Knowledge: A Community-Commanded Approach to Heritage Management in the Atacama Desert

Abstract This article presents the Zapar project, a community-commanded initiative developed in collaboration with the Atacameño Community of Toconao (northern Chile), which repositions remote sensing (RS) technologies through Indigenous governance and ethical frameworks. By embe...

Super-pupil beam engineering for enhanced confinement of azimuthally polarized depletion beams

Fluorescence depletion microscopy techniques require optical fields with a well-defined and spatially confined central intensity minimum to achieve sub-diffraction lateral resolution. Here, we present the design and experimental implementation of an azimuthally polarized, doughnu...

Heights of complete intersections in toric varieties

The height of a toric variety and that of its hypersurfaces can be expressed in convex-analytic terms as an adelic sum of mixed integrals of their roof functions and duals of their Ronkin functions. Here we extend these results to the 2 -codimensional situation by presenting a li...

Head-to-Tail Cyclization and D-Amino Acid Substitution Redesign the Biological Activities of a Naturally Occurring Amphibian Peptide

Peptide engineering has emerged as a powerful strategy to optimize naturally occurring peptides. Here, the amphibian skin peptide Hp-1891 from Boana pulchella was selected as a model scaffold to investigate the effects of two complementary engineering approaches, namely site-spec...

Workplace violence against social work and social services professionals in Spain: systematic review of prevalence, risk factors and prevention implications

Violence perpetrated by service users against social work and social services professionals has become an increasingly recognised occupational risk, with important implications for workers’ wellbeing and the quality-of-service delivery. Despite growing international attention to...

A Philosophy of Crisis? Methodological and Critical Perspectives

Building on Miguel de Beistegui's Crisis: A Critique (2026, Bloomsbury Academic), this forum exchange debates the book's central arguments and their significance for contemporary social, political, and ecological thought. In contrast to philosophers such as Jacques Derrida, who q...

Building masculinities through sport: a study of physical activity in prison contexts

This article examines how imprisonment reshapes incarcerated men’s masculine identities, focusing on how sport and physical activity contribute to the reproduction, negotiation, and transformation of masculinities in prison. The study draws on a two-and-a-half-year ethnography co...

A New Genus of Oak Gall Wasp, Striatoandricus Pujade-Villar (Hymenoptera: Cynipidae: Cynipini) from America with Descriptions of Two New Mexican Species

section. Descriptions of the genus and diagnostic characters, including DNA sequence data, are presented. This new genus is supported by both morphological and molecular data.

Blue-sky thinking about pronunciation research and teaching

Abstract In the fall of 2024, Ron Thomson and Tracey Derwing invited 15 pronunciation scholars representing several subspecialties to participate in a full-day symposium to discuss directions for pronunciation research. To prepare for the symposium, held in conjunction with the P...

Effects of Polyaromatic Film Interfaces on Cu Catalysts for Selective Electrochemical CO2 Reduction

Abstract Electrochemical CO2 reduction (CO2RR) offers a sustainable pathway to convert CO2 into energy-dense fuels and value-added chemicals, addressing both climate and energy storage challenges. This study investigates the effect of polyaromatic film (PAF) coatings on Cu-based...

A Taxonomic Review of the Gall Wasp Genus Saphonecrus Dalla-Torre and Kieffer and other Oak Cynipid Inquilines (Hymenoptera: Cynipidae) from Mainland China, with Updated Keys to Eastern Palaearctic and Oriental Species

Weld, 1944 from the USA are discussed.

Microwave-Assisted Extraction of a Quercetin-Containing Onion Leaf Extract for Potential Anti-Aging Cosmetic Applications

Onion (Allium cepa L.) is one of the most widely cultivated vegetables worldwide, while its leaves are discarded as agricultural waste despite being a valuable source of bioactive compounds. This study aims to investigate anti-aging cosmetic potential of onion leaf extract obtain...

The Mast Cell–Substance P Neuroimmune Axis in Allergic Contact Dermatitis and Atopic Dermatitis: Molecular Mechanisms and Pathophysiological Perspectives

Recent advances in cutaneous neuroimmunology have substantially expanded our understanding of inflammatory skin diseases, revealing an intricate bidirectional network linking peripheral sensory neurons, resident immune cells, and structural skin components. Among the mediators or...

Evanescent Absorption Spectroscopy of Transition Metal Dichalcogenide Materials Using Guided Photoluminescence in Si3N4 Photonic Waveguides

Abstract On-chip integration of two-dimensional transition metal dichalcogenides (TMDs) with photonic waveguides underpins a growing class of compact optoelectronic and sensing devices, whose performance depends on the optical absorption of the two-dimensional (2D) material in th...

Black holes and causal nonlinear electrodynamics

A bstract For generic theories of nonlinear electrodynamics (NLED) we investigate the implications of (a)causality on spherically-symmetric solutions of the Einstein-NLED equations that are asymptotic to a Reissner-Nordström (RN) spacetime. Equal-charge dyonic RN black holes are...

Hierarchical Bayesian calibration of mesoscopic models for ultrasound contrast agents from force spectroscopy data

Ultrasound-guided drug and gene delivery (USDG) is a promising non-invasive approach for targeted therapeutic applications. Mechanical properties of encapsulated microbubbles (EMBs), which serve as contrast agents, affect their interactions with ultrasound and are, thus, critical...

Search for signatures of outflow interaction around Cygnus X-3

Abstract Cygnus X-3 is a microquasar hosting a Wolf–Rayet star, recently identified as a Galactic PeVatron and a potential ULX source. We analyzed high-resolution H i data to search for interstellar medium interaction signatures across all proposed distances. We identify a candid...

Oveporexton for Narcolepsy Type 1 — Results from Two Phase 3 Trials

BACKGROUND: Narcolepsy type 1 is characterized by excessive daytime sleepiness, cataplexy, disrupted sleep, sleep paralysis, and hypnagogic or hypnopompic hallucinations. Oveporexton (TAK-861), an oral orexin receptor 2-selective agonist, reduced symptoms of narcolepsy type 1 in...

Aftershock Production in Mean Field Avalanche Models with Static Fields

Advanced seismic hazard assessment frameworks rely on stochastic models which include aftershock production in the form of branching or self-exciting point processes. Such empirical constructs are based on debated statistical laws observed across catalogs of natural seismicity, w...

Refining risk stratification after indeterminate urinary cytology: Evidence from Bladder EpiCheck

BACKGROUND: This study aimed to evaluate Bladder EpiCheck (BE) performance in detecting urothelial carcinoma (UC) and HG (high-grade) events in patients with indeterminate cytology and negative cystoscopy. METHODS: This prospective study included 63 patients who presented with in...
