Unusual SuperDARN Backscatter During the 11 May 2024 Geomagnetic Storm

open access: yesSpace Weather, Volume 23, Issue 12, December 2025.
Abstract A geomagnetic storm, one of the largest in this solar cycle, was launched on 10 May 2024, producing spectacular auroral displays that could be observed across the continental United States (US) at middle and low latitudes. In this study, we focus on a brief 20‐min interval during the peak of the storm when the Sym‐H index dropped to ∼ ${\sim} $

Molecules in the mirror: how SERS backgrounds arise from the quantum method of images [PDF]

open access: yes, 2014
The Raman coupling of light to molecular vibrations is strongly modified when they are placed near a plasmonic metal surface, with the appearance of a strong broad continuum background in addition to the normal surface-enhanced Raman scattering (SERS ...

Reciprocal associations between confidence in getting social support and academic expectancies and subjective task values: Stronger for first‐generation and transfer students

open access: yesBritish Journal of Educational Psychology, Volume 95, Issue 4, Page 1023-1046, December 2025.
Abstract Background Social support is assumed to play a key role in motivation at university, particularly for disadvantaged students, such as first‐generation and community college transfer students. However, longitudinal research investigating reciprocal associations between social support and motivation is lacking. Aims We examined such associations

Effects of the Accelerating Mathematics Performance With Practice Strategies (AMPPS) Intervention Program When Delivered During Summer in a One‐On‐One Virtual Format

open access: yesPsychology in the Schools, Volume 62, Issue 11, Page 4725-4739, November 2025.
ABSTRACT Despite extensive research suggesting the importance of students developing strong foundational math skills during early grades, more than 60% of 4th graders in the United States lack proficiency in mathematics. Such data are influenced by several factors, including summer learning loss in math, negative impacts from the COVID‐19 pandemic, and

How changes in post‐traumatic stress disorder (PTSD) severity mediate substance use disorder (SUD) severity during and after treatment for co‐occurring PTSD and SUD: Results from Project Harmony

open access: yesAddiction, Volume 120, Issue 11, Page 2245-2257, November 2025.
Abstract Background and Aims Post‐traumatic stress disorder (PTSD) commonly co‐occurs with substance use disorders (SUD). Comorbid PTSD and SUD (PTSD+SUD) is associated with greater severity and impairment and poorer treatment outcomes. Several interventions exist to treat PTSD, SUD and PTSD+SUD; however, research has yet to elucidate the indirect ...
