Autism Research, EarlyView.ABSTRACT Irritability is a prevalent and impairing feature associated with autism, yet remains poorly understood, particularly in adults. Drawing heavily on insights translated from pediatric and transdiagnostic literatures, we propose that irritability in autistic individuals often reflects a psychophysiological stress or threat response, rooted in a ...

NONLINEAR DYNAMICS OF A PENDULUM EXCITED BY A CRANK-SHAFT-SLIDER MECHANISM
, 2015 In this analysis, we consider the dynamics of a pendulum under vertical excitation of a crank-shaft-slider mechanism. The nonlinear model approaches that of a classical parametrically excited pendulum when the ratio of the length of the shaft to the ...

Carbon Energy, EarlyView.This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Droplet, EarlyView.A hand‐powered and mechanically programmable electrowetting‐on‐dielectric platform is demonstrated by integrating a contact‐separation triboelectric nanogenerator with a mechanically encoded punch‐card switch array. This unified mechanical–electrical architecture enables autonomous, portable, and robust droplet control for field‐deployable microfluidic

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
