Implementing multidomain non‐pharmaceutical interventions for preventing cognitive decline in community‐dwelling older adults in China: An embedded mixed‐methods implementation study of determinants and strategies

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION The WW‐FINGERS network has demonstrated the efficacy of multidomain non‐pharmaceutical interventions (NPIs) but left their real‐world implementation largely unexplored, prompting this study in Changxing County to identify key determinants and develop actionable strategies for community‐based delivery.

Coordinated DC Fault Ride‐Through Control for a Grid‐Forming Wind‐Storage System With VSC‐HVDC Integration Under Transmission Constraints

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.

Integral Sliding Mode Controller for Modular Multilevel Inverter‐Based PMSM Drives

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
The primary contribution of this work is the development of an integral sliding mode controller (ISMC) designed for motor speed and current regulation, optimized to enhance control performance with the unique MMLI structure. The proposed MMLI architecture offers a reduced number of switching components and passive elements, thereby minimizing system ...

Disturbance‐Resilient Voltage/Power‐Quality Management for Islanded Inverters Using Self‐Tuning Type‐3 Fuzzy Controller

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2816-2838, June 2026.
An adaptive fuzzy controller using an interval type‐3 fuzzy logic system replaces the SMC switching term to mitigate chattering while preserving global stability for islanded inverters. Simulations show lower THD, greater robustness to disturbances and parameter variations, and improved voltage‐tracking accuracy, with applicability to other uncertain ...
