Longitudinal associations of rapid eye movement (REM) sleep and slow‐wave sleep with plasma Alzheimer's disease biomarkers

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Data on how sleep architecture relates to progression of plasma Alzheimer's disease biomarkers remains limited. METHODS Sixty‐four cognitively unimpaired older adults (ages 55–90) underwent plasma collection twice 2.6 years apart and polysomnography proximate to the first plasma collection.

Application Research of Several Improved Active Disturbance Rejection Control Methods for Superheated Steam Temperature System

IET Smart Energy Systems, Volume 2, Issue 1, Page 49-61, March 2026.
A series of improved active disturbance rejection controller (ADRC) methods are proposed, and their parameter tuning processes are presented. They are comprehensively compared with regular proportional integral (PI) control and ADRC, and detailed superheated steam temperature (SST) simulations are carried out to verify their notably superior control ...

A Human–Robot Collaboration Control Framework for Supernumerary Robotic Limbs

Journal of Field Robotics, Volume 43, Issue 1, Page 34-48, January 2026.
ABSTRACT In this paper, a novel human–robot collaboration (HRC) framework is proposed to enhance the capability of Supernumerary Robotic Limbs (SRLs). The proposed framework consists of three key modules: human motion intention recognition, disturbance rejection control, and obstacle avoidance, all of which are crucial for SRLs in the process of HRC ...

Design of Novel Exponential PDN Controller via Quadratic Interpolation Optimiser for Nonlinear and Unstable Ball and Beam System

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel exponential proportional‐derivative controller with filter (exp‐PDN) for stabilising the nonlinear and underactuated ball and beam system. Unlike conventional PID‐based approaches, the proposed controller removes the integral term, resulting in faster transient responses and improved robustness.
