Characterisation of a high-Tc coil using short sample data [PDF]

, 1998
Characteristics of a circular superconducting coil made with BSCCO-2223/Ag tape depend on the amplitude and direction of the magnetic field in the windings. The effect can be estimated by studying a short sample of the same tape.

Experimental study of a transformer with superconducting elements for fault current limitation and energy redistribution

, 2005
Numerous proposed and developed superconducting fault current limiters and self-limiting transformers limit successfully fault currents but do not provide uninterrupted supplying of consumers. A design investigated in the work combines the functions of a

Superconducting traction transformer: traction - the HTS transformer killer application? [PDF]

, 2021
An ongoing project to develop HTS traction transformers for the Chinese Fuxing high-speed train is demonstrating that the high power density accessible using high temperature superconductors (HTS) can produce spectacular results: the existing 6.5 MVA traction transformers can be replaced with drop-in superconducting transformers which can achieve ...

HT-Net: A Hybrid Transformer Network for Fundus Vessel Segmentation

Sensors, 2022
Doctors usually diagnose a disease by evaluating the pattern of abnormal blood vessels in the fundus. At present, the segmentation of fundus blood vessels based on deep learning has achieved great success, but it still faces the problems of low accuracy and capillary rupture.

Spherical Skin Model: Stratified Co‐Culture of Fibroblasts and Keratinocytes on Spherical Beads Toward Compound Screening

Advanced Healthcare Materials, EarlyView.
Models of the human skin must combine the relevant biological contents and suitable biomaterials with the correct spatial organization. Performing compound screening on such in vitro models also requires fast and reproducible production methods of the models.

Operational research on a high-T c rectifier-type superconducting flux pump [PDF]

, 2016
High-T$_{c}$ superconducting (HTS) flux pumps are capable of injecting flux into a superconducting circuit, which can achieve persistent current operation for HTS magnets. In this paper, we studied the operation of a rectifier-type HTS flux pump.
