Improve the quality of "dead band" audio-frequency magnetotelluric impedance data using electric field remote reference

open access: yes矿业科学学报, 2022
Magnetic remote-reference is the most practical noise suppression method in magnetotelluric data processing.In actual audio-frequency magnetotelluric (AMT) sounding observation, usually the "one with three" or "one with four" acquisition method is used ...

Do metal implants for total hip arthroplasty affect bioelectrical impedance analysis? A retrospective study

open access: yesBMC Musculoskeletal Disorders, 2023
Background Evaluation of body composition after total hip arthroplasty (THA) is essential because it can be used to evaluate muscle and functional recovery. Muscle volume and degeneration are evaluated using computed tomography (CT).

Monitoring Freeze-Damage in Grapefruit by Electric Bioimpedance Spectroscopy and Electric Equivalent Models

open access: yesHorticulturae, 2022
Grapefruit is a cold-sensitive citrus fruit, and freezing can spoil the harvest when the fruit is still on the tree and even later during manufacturing and transport due to inappropriate postharvest management.
