Corneal endothelial cell changes and surgical results after Ahmed glaucoma valve implantation: ciliary sulcus versus anterior chamber tube placement

Scientific Reports, 2021
We compared the changes in corneal endothelial cells and surgical outcomes after Ahmed glaucoma valve (AGV) implantation with the valve tip inserted either into ciliary sulcus (CS) or anterior chamber (AC). We retrospectively reviewed the medical records

Prediction of Nonsinusoidal AC Loss of Superconducting Tapes Using Artificial Intelligence-Based Models

IEEE Access, 2020
Current is no longer sinusoidal in modern electric networks because of widespread use of power electronic-based equipments and nonlinear loads. Usually AC loss is calculated for pure sinusoidal current, while it is no longer accurate when current is ...

An Adipokinetic Hormone Acts as a Volume Regulator in the Intertidal Gastropod Mollusk, Aplysia californica

Frontiers in Endocrinology, 2018
Adipokinetic hormone (AKH) is a multifunctional neuropeptide in the gonadotropin-releasing hormone superfamily. In insects, AKH acts to mobilize energy stores during times of high energetic demand, but has been shown to have other effects.

Analysis of AC winding loss of permanent magnet synchronous traction motor with high power

机车电传动, 2022
In a multiple-pole and high-power PMSTM with high fundamental frequency, the harmonic frequency of the internal magnetic field increases accordingly. The harmonic magnetic field will induce eddy current in the winding, resulting in high-frequency eddy ...

AC Losses in Superconductors

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1969
A brief review is presented on the ac losses of superconductors in the low-frequency, high-frequency, and weak-field regions. Special emphasis is given to the hysteresis loss which is the main part of the low frequency losses. Existing data of the low-frequency losses are collected to be shown in a single figure and it is shown that most of these can ...
