Ce 3+ ‐Activated BASL Glass With High Verdet Constants and Efficient Luminescence

ABSTRACT Trivalent cerium (Ce 3+ )‐activated optical materials are important for magneto‐optical devices, radiation detection, and advanced photonic systems; however, their performance in oxide glasses has been limited by the instability of Ce 3+ at high concentrations during gla...

Asymmetric Vegetation Responses to Flood Exposure in the Chi River Basin: A Multi-Temporal Remote Sensing and Machine Learning Investigation

Flooding and drought alternate in many tropical floodplains, but how vegetation responds to both hazards over multiple years remains poorly quantified. We examined vegetation–flood associations in the Chi River Basin, Northeast Thailand, drawing on Sentinel-2 imagery from 2020, 2...

Repositioning Altar de Sacrificios on the Ancient Maya Landscape: UAS Settlement Survey of the Upper Usumacinta Confluence Zone

Abstract Despite its record among early twentieth-century explorers and being one of the first sites excavated in southwestern Petén, Guatemala, Altar de Sacrificios has eluded Maya scholarship for much of the last half-century. This article aims to redefine Altar’s position on t...

Large-scale patterns of self-reported mood and sleep across the day and week on an online cognitive-training platform

Mood follows a well-documented circadian rhythm. Sleep timing and duration are similarly shaped by biological and social factors. However, large-scale, real-world data on how these patterns vary across demographic groups remain limited. Prior studies often rely on laboratory data...

Implications of Wearable Sleep Health Technology for Cardiovascular Health Assessment and Interventions: A Narrative Review

Sleep health is a multidimensional component of cardiovascular health, and modulating sleep as a cardiometabolic risk factor requires accurate measurement. Numerous technologies have emerged in the last 50 years to longitudinally characterize sleep over time in ambulatory setting...

Early metal-enriched baryon cycling before the midpoint of cosmic reionization

Abstract Models predict that chemical enrichment and gas redistribution should begin rapidly once star formation starts, but direct constraints at the earliest epochs have been scarce. Here we show that metal-enriched gas in multiple ionic phases was already present around galaxi...

Political Endorsements by TikTok Influencers: Parasocial Interaction, Identification, and Support for Political Candidates

This study examines political persuasion on TikTok by testing how influencers’ direct address and media source labels shape audience responses to a political endorsement video. Using a preregistered 2 × 2 online survey experiment with 486 U.S. adults, we found that participants e...

Stellar masses of optically dark galaxies: uncertainty introduced by the attenuation law and star-formation histories

Abstract Recent studies using JWST have suggested that some high-redshift galaxies may be ultra-massive, thereby challenging standard models of early galaxy formation. We analyse the stellar masses using different modelling assumptions and in conjunction with new data of three ga...

A Scandian pressure-temperature path for the northern Moine Nappe, Scotland

The Northern Highlands Terrane in northwestern Scotland preserves a polyphase metamorphic history dominated by Scandian (435-415 Ma) tectonism. Phase equilibria modeling, major and trace element compositions in metamorphic phases, and textural observations are used to construct a...

The North American CORDEX-CMIP6 WRF evaluation run: comparing historical simulations from 25 km to convection-permitting scales

Earth system models (ESMs) provide essential insight into large-scale climate variability and change but often lack the spatial resolution required to represent fine-scale processes critical for regional impacts and adaptation planning. To help address this gap, we present an upd...

Vacuum ultraviolet dual-comb spectroscopy

The optical frequency comb has made a significant impact in precision spectroscopy and on our ability to probe atomic, molecular and, recently, nuclear transitions to further our understanding of their fundamental properties and how their dynamics and complex interactions affect...

Inquiry as Stance: Teachers Creating Space for Problem-Posing

This research study examined professional learning within an inquiry group and teachers’ perspectives on how this context differed from their district-mandated professional learning time. The action research is framed within an inquiry as stance perspective around knowledge-of-pr...

Examining Anxiety as an Additional Antecedent to Trust and Commitment in Financial Planning

Abstract Drawing on Morgan and Hunt’s (1994) theory of trust and commitment, this study extends prior research by examining financial anxiety as an antecedent to trust and relationship commitment in client-planner relationships. Survey data from 430 financial planning clients wer...

Star formation powers optical line emission from the CGM

Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line maps for a large sample (72) of normal, low-redshift galaxies spanning three orders of magnitude in...

The Dream Garden Game: Integrating Gamification and Playful Design to Support Public Participation in Urban Greening Policymaking

As greening initiatives are increasingly implemented by public agencies to enhance climate resilience in urban environments, meaningful engagement with communities to support public participation becomes critical. While it has been well-documented that effective community engagem...

Does Office Type Determine Gendered Campaign Messages?

This study examines how candidates’ gender shapes campaign messaging across different branches and levels of political office. Prior research offers mixed evidence on whether women are more likely than men to emphasize communal traits and women-related policies, often because gen...

Community-based Participatory Translation: A Translation Methodology for Community-Based Participatory Research

Community-based participatory research (CBPR) refers to an approach to conducting research that equitably involves community members, researchers, and other stakeholders in the research process. CPBR centers the research on the experiences of those most affected by the issue, and...

A Causal Model for Prehospital Blood Transfusion and Mortality in Traumatic Hemorrhagic Shock

OBJECTIVES Utilization of prehospital blood transfusion (PBT) as a treatment for traumatic hemorrhagic shock (THS) has been expanding nationally, yet evidence supporting the practice in some operational environments remains limited. Development of strong scientific evidence to su...

An observational perspective on precipitation efficiency of mesoscale convective systems over the Asian Monsoon Region

This study investigates the precipitation efficiency ( ε ) of tropical mesoscale convective systems (MCSs) using satellite-based precipitation rates (P˙) and reanalysis cloud, ice, and liquid water paths (CWP, IWP, LWP). We define ε as the ratio of P˙ to CWP, following Li et al....

Limitation of pantothenate bioavailability in Anopheles stephensi by second-generation pantazines enhances restriction of Plasmodium development

Plasmodium parasites require pantothenate (Pan) from their hosts to synthesize coenzyme A (CoA), an essential metabolic cofactor. While blood-stage parasites can utilize both Pan and the immediate CoA precursor phosphopantetheine from mammals to synthesize CoA, mosquito-stage par...
