Muscle Synergies Facilitate Computational Prediction of Subject-Specific Walking Motions. [PDF]

open access: yes, 2016
Researchers have explored a variety of neurorehabilitation approaches to restore normal walking function following a stroke. However, there is currently no objective means for prescribing and implementing treatments that are likely to maximize recovery ...

Simple finite-time sliding mode control approach for jerk systems

open access: yesAdvances in Mechanical Engineering, 2019
This article describes an easy way to apply active control upon all jerk systems for which the linear part of the third-order differential jerk equation strongly depends on acceleration and velocity.

Feed rate modeling in circular–circular interpolation discontinuity for high-speed milling [PDF]

open access: yes, 2013
In this paper, a modeling approach is presented in order to evaluate feed rate during a circular interpolation in high-speed milling. The developed model depends on the type of discontinuity and the kinematic performance of the machine tool.

Jerk Reduction Control of Mechanical Transfer System

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006
This paper considers vibration suppression of a mechanical transfer system, where the work is connected with the hand flexibly. We adopt the idea of jerk reduction of the hand. From the equation of motion, we first derive a state equation including the jerk and acceleration of the hand, but excluding the displacement and velocity of the work.

Design Procedure for Motion Profiles with Sinusoidal Jerk for Vibration Reduction

open access: yesApplied Sciences, 2023
High-speed motions performed by industrial machines can induce severe vibrations that degrade the positioning accuracy and efficiency. To address this issue, this paper proposes a novel motion profile design method utilizing a sinusoidal jerk model to ...

Life‐Threatening Bradycardia in Anti‐NMDA‐Receptor Encephalitis and a Novel Use for Permanent Pacing

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pediatric anti‐NMDA receptor encephalitis (pNMDARE) is an autoantibody‐mediated disorder that can cause severe autonomic dysfunction, including symptomatic bradycardia and asystole. Dysautonomia can last for years, making it very challenging to manage.

Jerk-Bounded Trajectory Generation Method using Digital Convolution [PDF]

open access: yes, 2009
This paper proposes a jerk-bounded trajectory generation method using a digital convolution. The suggested jerk-bounded trajectory is able to reduce unexpected damages for a robot motion control system and to improve a tracking accuracy/speed of the ...

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.
