Unraveling the Origin of the Repulsive Interaction between Hydrogen Adsorbates on Platinum Single-Crystal Electrodes.

Hydrogen adsorption on platinum (Pt) single-crystal electrodes has been studied intensively in both experiments and computations. Yet, the precise origin and nature of the repulsive interactions observed between hydrogen adsorbates (H) have remained elusive. Here, we use first-principles density functional theory calculations to investigate in detail the interactions between H on Pt(111), Pt(100), and Pt(110) surfaces.

Innovating a Community-driven Enumeration and Needs Assessment of People Experiencing Homelessness: A Network Sampling Approach for the HUD-Mandated Point-in-Time Count.

To enumerate people experiencing homelessness in the U.S., the federal Department of Housing and Urban Development (HUD) mandates its designated local jurisdictions regularly conduct a crude census of this population.

Research Priorities for Childhood Apraxia of Speech: A Long View.

This article introduces the Special Issue: Selected Papers From the 2022 Apraxia Kids Research Symposium. The field of childhood apraxia of speech (CAS) has developed significantly in the past 15 years, with key improvements in understanding of basic biology including genetics, neuroscience, and computational modelling; development of diagnostic tools and methods; diversity of evidence-based interventions with increasingly rigorous experimental designs; and understanding of impacts beyond impairment-level measures. Papers in this special issue not only review and synthesize the some of the substantial progress to date but also present novel findings addressing critical research gaps and adding to the overall body of knowledge.

The Locations of Palestine and the U.S. in the Global Map of Homelessness: Part I.

It's now well appreciated that social determinants of health are the strongest predictors of our health and well-being. A good argument could be made that housing is at the top of the pyramid of these determinants. And, surprisingly, housing is also the social determinant that could rapidly turn on a dime-that is, with sufficient political will, creating access to housing could be radically expanded in short order.
