To Tell or Not to Tell: Self-(Non)Disclosure to Parents Across Three Cultures

In Western contexts, self-disclosure is commonly considered beneficial, while nondisclosure is often viewed as dysfunctional. The current research challenges the universality of this assumption about nondisclosure by examining the tendencies, mechanisms, and psychological consequ...

Gut microbiota profile in school-aged children with vitamin A depletion and vitamin E deficiency: A cross-sectional study

Vitamin A (VitA) and vitamin E (VitE) deficiencies can result in significant health consequences in children. The role of the intestinal microbiota in these vitamin deficiencies has been scarcely explored. This cross-sectional study aimed to analyze the relationship of VitA deple...

A Mobile-Centric Approach to Improving the Performance of Decentralized Wireless Networks

The proliferation of wireless devices and intelligent environments has led to increasingly dense, interference-prone Wireless Local Area Network (WLAN) deployments. Recent amendments, such as IEEE 802.11ax/be, aim to enhance spatial reuse (SR) by optimizing spectrum efficiency. H...

Impact of undernutrition on apoptotic pathways and thymocyte development in rats: insights into caspase activation and mitochondrial dysfunction

Abstract Undernutrition significantly compromises immune function, particularly in vulnerable populations. This study explored the effects of undernutrition on apoptotic pathways and thymocyte development in rats, shedding light on potential mechanisms underlying immunosuppressio...

Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1

Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

First Reported Human Case of Primary Lymphocutaneous Nocardiosis Caused by Nocardia shinanonensis

Nocardia species are ubiquitous environmental microorganisms that can cause localized cutaneous, pulmonary or disseminated infections in humans. Primary cutaneous nocardiosis is uncommon and may present as cellulitis, abscesses, ulcers, granulomas or lymphocutaneous disease chara...

Volcanic textures control the mechanical behaviour of Mesoamerican obsidians

Abstract Obsidian—natural volcanic glass—was exploited for millennia and played a central role in the technological and socio-economic development of pre-Hispanic societies across Mesoamerica. The selection of obsidian from specific deposits has been linked to differences in visu...

Culinary Chemistry as a Platform for Interfacial Materials Design

ABSTRACT This Review examines culinary systems as experimentally accessible models of interfacial materials design. Culinary operations, including emulsification, foaming, gelation, spherification, controlled heating, smoking, and dehydration, govern gas‐liquid, oil‐water, solid‐...

Advanced oxidation processes for 2,4-dichlorophenoxyacetic acid in aqueous media: evidence gaps, mechanistic insights and emerging directions

Abstract The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) remains a relevant aquatic contaminant because parent-compound disappearance does not imply mineralization, detoxification or treatment readiness. This systematic review synthesizes recent evidence on advanced oxidatio...

Integrative systematics of the Neotropical doryctine wasp genus Panama (Hymenoptera: Braconidae) and related genera with the description of a new genus

Context Panama Marsh (Hymenoptera: Braconidae) is a Neotropical doryctine wasp genus erected to contain a single species, P. canalia Marsh, primarily based on its distinctly extended pronotum forming a pronotal collar. Although several morphologically similar genera also possess...

Stratosphere–troposphere exchange and surface ozone pollution over tropical regions: a case study of Rossby wave breaking and tropopause folding

Abstract. Stratosphere-troposphere exchange (STE) is a key process by which ozone-rich stratospheric air enters the troposphere, influencing surface air quality. This study analyses an atypical STE event over North America between 6 and 14 March 2016, coinciding with a Phase I oz...

Topological control of local electroneutrality in confined electrolytes

Topology governs finite-size violations of local electroneutrality in confined electrolytes. Within Poisson-Boltzmann theory, we show that this topological control gives rise to a universal hierarchy of deviations in spherical, cylindrical, and planar confinement. We quantify thi...

Modulating Access: Contributions From Latin America to the Study of Mobility and Care in the Urban Periphery

ABSTRACT This article examines theoretical and methodological innovations from Latin America in the study of urban mobility, exploring the relationship between access and care as experienced by domestic workers living in mass social housing projects on the outskirts of Mexico Cit...

Influence of functional traits and trait syndromes on the vulnerability of amphibians and reptiles in the tropical dry forest of Oaxaca, Mexico

Abstract Tropical dry forests are among the most threatened ecosystems worldwide, yet their biodiversity remains understudied compared to humid tropical forests. We integrated functional trait ecology with environmental vulnerability assessments to evaluate multi‑causal disturban...

Joint Modeling of GD-1 and C-19 as Old Streams

Abstract DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multihalo potential of a Milky Way–like galaxy based on a cosmological Milky Way–like simulation. The number of subhalos decreases with time, and the subhalo-stream en...

Cleft Palate Surgery: Evolving Surgical Techniques and Reconstructive Principles for Oronasal Fistula and Velopharyngeal Dysfunction: A Narrative Review

Background Despite more than a century of surgical innovation, no single palatoplasty technique has demonstrated consistently superior outcomes across the spectrum of cleft palate phenotypes. Objective This review examines the historical evolution of cleft palate reconstruction a...

Nutritional Programming via Maternal Protein Restriction Mitigates Long-Term Consequences of Acute Kidney Injury

The kidney is highly sensitive to prenatal and early-life environmental influences. Maternal protein restriction (MPR) can alter renal development and may modify susceptibility to chronic kidney disease (CKD) following acute kidney injury (AKI). We investigated whether MPR during...

Validation of Turbulence Models for Predicting Pressure Coefficients for Natural Ventilation Purposes on an Isolated Low-Rise Building

The wind pressure coefficient CP is a key aerodynamic parameter for describing wind-induced pressure fields on building envelopes and is widely used as an input in air flow network (AFN) models. Most CFD validation studies rely on wall-averaged CP or a limited number of center-li...

Whey Protein–Polysaccharide Nanocomplexes: Structure–Function Characterization and Bone-Related Outcomes in Ovariectomized Rats

Background/Objectives: Estrogen deficiency is associated with impaired bone mineralization and deterioration of bone quality. Protein–polysaccharide nanostructures have attracted interest as food-grade formulations because their physicochemical properties can be modified by the n...

Symmetry-Based Reformulation of the Gravity Sensitivity Matrix for Efficient Regional-Scale Gravity Imaging

Regional-scale gravity imaging is limited by the size of the sensitivity matrix: a direct three-dimensional formulation of the gravity operator requires on the order of 1013 coefficients, making explicit storage infeasible on standard hardware. We exploit two symmetry properties...
