Living with the Unknown: Intolerance of Uncertainty in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is marked by pervasive uncertainty due to fluctuating motor and non‐motor symptoms, variable treatment response, and an unpredictable clinical course. Intolerance of uncertainty (IU), a tendency to perceive ambiguity as threatening and respond with worry, avoidance, or decisional paralysis, may be ...

Development of Magnetorheological Engine Mount Test Rig

MATEC Web of Conferences, 2017
Ride comfort is an important factor in any road vehicle performance. Nonetheless, passenger ride comfort is sometimes affected by the vibrations resulting from the road irregularities.

Design, Analysis, and Experimental Validation of a Variable‐Gap Magnetorheological Damper for Seat Suspension

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Life history stability under climate change: a wildflower at the northern edge of its range

Nordic Journal of Botany, EarlyView.
Stabilities of life history traits for a widespread native perennial wildflower, Rudbeckia laciniata L., are described for five populations near the northern edge of its range in North America. Theory proposes that such populations experience variable levels of stress as suitable abiotic conditions shift north or south from year to year, which ...

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Transforming a Poaching Hotspot: Embedded NGO Governance Between State and Community in Southern China

Public Administration and Development, EarlyView.
ABSTRACT This article examines how a local environmental NGO in southern China transformed Guantouling Hill, once a prominent poaching hotspot along the East Asian–Australasian Flyway, into a recognised model of community‐based biodiversity conservation.

Simulation analysis and optimization of ride quality of in-wheel motor electric vehicle

Advances in Mechanical Engineering, 2018
In order to evaluate the influence of unsprung mass on ride comfort for an in-wheel motor electric vehicle, an improved genetic algorithm based on fitness evaluation was proposed to optimize the suspension system.

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.
