Current developments in surface electromyography
Turkish Journal of Medical Sciences, 2023 Surface electromyography (surface EMG) is a primary technique to detect the electrical activities of muscles through surface electrodes. In recent years, surface EMG applications have grown from conventional fields into new fields. However, there is a gap between the progress in the research of surface EMG and its clinical acceptance, characterized by ...

Prevalence of Deformation‐Scale Surface Currents
Geophysical Research Letters, 2023 Understanding the transport of large ocean currents, like the Gulf Stream, has been of interest since the early days of oceanography. There has been less attention on the widths of the currents, although there exist several theoretical predictions.

Forecast uncertainty and ensemble spread in surface currents from a regional ocean model
Frontiers in Marine Science, 2023 An operational ocean Ensemble Prediction System (EPS) for the coastal seas off Northern Norway is evaluated by comparing with high-frequency radar current speed estimates. The EPS is composed of 24 members for which the ocean current is not perturbed nor

Response of a Small River Plume on Wind Forcing
Frontiers in Marine Science, 2021 Wind forcing is the main driver of river plume dynamics. Direction and magnitude of wind determine position, shape, and size of a river plume. The response of river plumes on wind forcing was simulated in many numerical modeling studies; however, in situ
