Filipino migrant workers navigating war online: Digital performative citizenship and the construction of belonging during the Israel–Hamas war

Research on migrant workers’ use of social media has largely focused on everyday contexts. Little attention has been given to their practices during major crises in their host countries where they lack citizenship. This study examines how Filipino live-in caregivers in Israel use...

Monotonicity, topology, and convexity of recurrence in random walks

We consider nonhomogeneous random walks on the two-dimensional positive quadrant N2. In the 1960’s the following question was asked for N2: is it true if such a random walk X is recurrent and Y is another random walk that at every point is more likely to go down and more likely t...

Dermatological Diseases and Household Behavioral Spillovers: A Conceptual Framework

Background: Chronic diseases may generate behavioral responses extending beyond the affected individual. Although family health effects and behavioral spillovers have been examined in health economics and behavioral research, their relevance to dermatological disease management h...

Defining Success in Ptosis Surgery: Outcome Heterogeneity and Priorities for Standardization

Ptosis surgery aims to restore eyelid position, visual function, facial expression, and, in children, visual development. Yet reported success rates reflect how success is defined as much as what surgery achieves. Studies use different eyelid-height thresholds, symmetry criteria,...

The gene-regulatory evolution of the human skeleton

Abstract Skeletal modifications were central to human evolution, enabling adaptations for bipedalism, large cranial vaults and childbirth 1 . Despite their importance, the genetic changes that gave rise to the unique human form remain mostly unknown 2 . Here we systematically map...

Transition to Double‐Cell Mock Walker Circulations With Surface Warming Explained by Periodic Convection

Abstract Idealized mock Walker simulations are widely used to study the interactions between overturning circulation and convection in the tropics. Previous studies documented a transition from a single‐cell to a double‐cell mock Walker circulation when the average sea surface te...

Spatial mixed models for assessing environmental exposure effects on the microbiome

Environmental exposures such as air pollution may influence human health partly through microbiome, but statistical modeling is challenged by spatial dependence across regions and ecological correlations among taxa. We propose SpaMixed, a novel spatial mixed modeling framework fo...

Limitation of O3 Dry Deposition by Elevated-Source NO Emissions and Surface Dryness in Urban Environments

Abstract Tropospheric ozone (O3) is a major air pollutant that adversely affects human health, climate and ecosystems. However, its removal in urban environments remains poorly represented in air-quality and climate models, largely due to limited flux-based observations of urban...

Mediterranean Late Bronze Age copper ingots: A new lead isotope-based synthesis

Within the dynamic exchange networks of the Mediterranean Late Bronze Age, copper ingots are central to reconstructing the scale, organization, and intensity of economic and cultural contact. Yet, whether Late Bronze Age copper ingots derived from a single copper source or were m...

Taxonomic revision of the genus Methanobrevibacter, description of Methanomonile shimae gen. nov. sp. nov., and proposal of Methanobrevibacteraceae fam. nov

Recent phylogenomic analyses revealed that the genus Methanobrevibacter , which consists almost exclusively of representatives from the intestinal tract of animals, is severely underclassified. Based on the large relative evolutionary divergence between individual subclades, memb...

Factors affecting family consent to corneal donation at a hospital-based eye bank in a tertiary Israeli medical center

Purpose To identify clinical, demographic, and situational factors associated with family consent to corneal donation in a culturally diverse Israeli medical center operating under an opt-in system. Methods This retrospective observational study included 824 deceased individuals...

A Transdiagnostic IPT-Based Intervention for Global Crises

This Psychotherapy Tools article presents an ultra-brief, transdiagnostic crisis intervention protocol designed for use during national emergencies such as war, natural disasters, or pandemics. Based on interpersonal psychotherapy (IPT) and integrating skills from cognitive-behav...

A New Case of Lethal Congenital Contracture Syndrome Type 3 With Hyperinsulinism and Optic Atrophy

ABSTRACT Lethal congenital contracture syndrome 3 (LCCS3, MIM #611369) is a rare autosomal recessive neuromuscular disorder caused by biallelic loss‐of‐function (LOF) variants in PIP5K1C , reported in only two families to date. It typically presents with severe fetal akinesia, ar...

Unveiling the role of neurotransmitters in Nrf2 pathway activation in HaCaT cells: toward novel brain-skin redox biomarkers

Oxidative stress is a central feature of both cutaneous biology and neurological disorders; however, the endogenous signals that activate the Nrf2 antioxidant pathway in the skin remain poorly defined. Here, we identified dopamine (DA) as a selective activator of Nrf2-dependent c...

Tunable Porphyrin Cage Based on Designed Electric Field for Methane Capture and Oxidation

Abstract Methane is a generic chemical feedstock, and its conversion to methanol can provide an alternative fuel. We herein provide a first-principles-based strategy for designing a catalyst that operates in a synchronized catalytic cycle and efficiently converts methane into met...

Adverse Childhood Experiences and New-Onset of PTSD During Military Service.

INTRODUCTION: Exposure to adverse childhood experiences (ACEs) has been increasingly recognized as a potential risk factor for later psychopathology; however, its role in the development of post-traumatic stress disorder (PTSD) during military service remains insufficiently chara...

Mortars and plasters at Herod's Caesarea Maritima: integration of imported and local construction technologies

Abstract Building materials from different architectural elements at Herodian Caesarea Maritima (22–4 BCE ) provide evidence for a variety of compositions tailored to specific construction functions, demonstrating the extent of Roman technological influence on Herod's architectur...

Elucidating Sodium-Ion Storage Mechanisms in Bowl-Shaped Hierarchical Porous Carbon Anodes: A Combined Solid-State NMR and EPR Approach

Abstract Understanding sodium-ion storage in carbon anodes is essential for fabricating efficient batteries via the design of carbon architectures with optimized pores, defects, and surface area. Previous mechanistic studies have mainly focused on hard carbon anodes with poorly d...

Reversing the pipeline: a ‘human-first’ multi-omics approach to cardiovascular discovery

Despite significant biomedical advances, cardiovascular disease remains a leading cause of global mortality. The traditional 'bench-to-bedside' research pipeline, which heavily relies on animal models to guide clinical translation, is often hampered by species-specific physiologi...

Extensions of unirational groups

Abstract We undertake a study of extensions of unirational algebraic groups. We prove that extensions of unirational groups are also unirational over fields of degree of imperfection 1, but that this fails over every field of higher degree of imperfection, answering a question of...
