Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Valence Asymmetries of Traits in Dating Contexts
European Journal of Social Psychology, EarlyView.ABSTRACT Research on traits in dating contexts has typically focused on trait content. We instead examined structural differences in trait frequency and similarity. Prior work suggests that positive information is more frequent, whereas negative information is more diverse and less similar.

From Studying Real Hummingbirds to Designing Hummingbird-Like Robots—A Literature Review
IEEE Access, 2019 In this paper, the interpretation of hovering flight for hummingbirds is studied from a hummingbird morphology perspective (muscle and skeleton) including weight distribution, followed by a discussion of hovering aerodynamics. Next, by studying the scale

Feminist Anthropology, EarlyView.Abstract This essay examines how gendered expectations, structural precarity, and institutional hierarchies shape research practices, knowledge production, and career trajectories in biological anthropology. Taking the figure of the “strong woman” as an entry point, it questions celebratory narratives of resilience that frame endurance as an individual

The International Journal of Health Planning and Management, EarlyView.ABSTRACT Pakistan has hosted Afghan refugees for more than four decades, in one of the world's most protracted displacements of people. Afghan refugees receive health services through United Nations High Commissioner for Refugees (UNHCR) and non‐governmental organisation (NGO) supported programmes alongside public sector facilities at every tier.

Human Resource Development Quarterly, Volume 36, Issue 1, Page 89-112, Spring 2025.Abstract Retirees re‐entering the workforce, popularly termed as bridge employment, is a phenomenon that is anticipated to increase in the coming years. Though research establishes that these employees have unique aspirations and work motives (see Mazumdar et al., 2020), primary research on how the retirement transition and bridge employment shape each
