Remembering Interracial Intimacies: South Asian Perspectives on Black/Brown Sex and Romance in Colonial East Africa

open access: yesGender &History, Volume 38, Issue 3, Page 833-845, October 2026.
ABSTRACT Bringing together historical evidence, postcolonial fiction and memory work, this study recovers South Asian cultural attitudes towards interracial heterosexual romance from the margins of East African history. It asks why Black/brown intimacy was treated as taboo and denied legitimacy within South Asian diasporic communities in British‐ruled ...

Understanding the Immune Response Changes to Clinical Interventions for Epstein–Barr Virus Infection Prior to Lymphoma Development in Children After Organ Transplants (UNEARTH)

open access: yesPediatric Transplantation, Volume 30, Issue 10, October 2026.
The T cell and Natural Killer cell immune responses in primary EBV infection in children or during progression to PTLD are not well characterized. By performing detailed prospective immunological phenotyping through the first year after 278 pediatric organ transplants, we will unearth pathways that may inform EBV oncogenesis progression.

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1422-1432, July 2026.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Design and Simulation of a Carrier PWM‐Based Capacitor to Support a Dynamic Voltage Restorer for Voltage Swell and Voltage Mitigation in the Distribution System

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (

Footholds for pioneers: How geomorphic features accelerate early marsh assembly

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Ecosystem transitions from bare to vegetated states often stall at early stages, before the biogeomorphic feedbacks needed for further expansion take hold. In aquatic systems, this bottleneck is especially common where inundation and hydrodynamic conditions may impose strong abiotic filters on pioneer establishment.
