Uniplanar compact wideband bandstop filter

IEEE Microwave and Wireless Components Letters, 2003
A uniplanar wideband bandstop filter is proposed using two bent open-end stubs. The proposed filter consists of the bent connecting line of /spl lambda//sub g//2 between two bent /spl lambda//sub g//4 stubs, which results in wideband design with a rejection bandwidth of 90% at 2.05 GHz.

Neuromuscular fatigue reduces force responsiveness when controlling leg external forces

Physiological Reports, Volume 13, Issue 16, August 2025.
Abstract Agile movement requires precise control of ground reaction forces, yet the impact of neuromuscular fatigue on this control remains incompletely understood. We investigated how leg muscle fatigue affects the nervous system's ability to modulate vertical ground reaction forces, hypothesizing that fatigue would impair responsiveness, and accuracy.

Acute Cervical Vagus Nerve Stimulation Modulates Gastric Slow Waves in the Distal Rat Stomach

Neurogastroenterology &Motility, Volume 37, Issue 7, July 2025.
Slow waves were mapped on the rat gastric serosa during acute cervical vagus nerve stimulation with three stimulation protocols. The medium and high cVNS protocols modified slow wave frequency, and slow wave propagation was temporarily disrupted during stimulation in all subjects.

Reducing ECG Artifact From Left Ventricular Assist Device Electromagnetic Interference

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Left ventricular assist devices (LVADs) generate electromagnetic interference that causes high‐frequency noise artifacts on 12‐lead ECGs. We describe the causes of this interference and potential solutions to aid ECG interpretation in patients

Modeling Emotional Arousal With Turbulence Measured by EEG

Psychophysiology, Volume 62, Issue 6, June 2025.
ABSTRACT Turbulence‐like dynamics in brain activity have been proposed as a signature of systems operating near criticality, and may reflect changes in neuronal function associated with emotional states. In this paper, we hypothesize that motor behavior linked to emotional expression modulates turbulence, reflecting a shift towards more streamlined ...
