Motion Control of Musculoskeletal Systems with Redundancy

Hyunjoo Park, Dominique M. Durand

The loss of volitional motor control of the musculoskeletal system has a variety of causes, including spinal cord injury and neurological diseases. In cases where the peripheral nervous system and musculoskeletal system remain intact, such as in spinal cord injury and stroke, …

Epidural Spinal Cord Recordings (ESRs): Sources of Artifact in Stimulation Evoked Compound Action Potentials

Ashlesha Deshmukh, Megan L. Settell, Kevin P. Cheng, Bruce E. Knudsen et autres

Introduction: Evoked compound action potentials (ECAPs) measured using epidural spinal recordings (ESRs) during epidural spinal cord stimulation (SCS) can help elucidate fundamental mechanisms for the treatment of pain, as well as inform closed-loop control of SCS. Previous studies have used ECAPs to …

Colorimetric Detection of Furfural with Enhanced Visible Absorption of Furfural-DNPH in Basic Conditions

Hyunjoo Park, Eun Young Kim, Taehyun Jun, Sang‐Hyun Pyo et autres

Furfural is an intermediary toxic aldehyde compound produced during heat-induced food processing and storage. Furfural is also formed by the degradation of cellulosic insulation in oil-immersed electric potential transformers, whose level is an important indicator of aging for replacement. In this study, …
