A Study of Reverse Characteristics of GaN-on-Si Quasi-Vertical PiN Diode with Beveled Sidewall and Fluorine Plasma Treatment.

In this work, we show a high-performance GaN-on-Si quasi-vertical PiN diode based on the combination of beveled sidewall and fluorine plasma treatment (BSFP) by an inductively coupled plasma (ICP) system. The leakage current and breakdown voltage of the diode are systematically studied. Due to the beveled sidewall treated by the fluorine plasma, the diodes achieve an excellent breakdown voltage (V) of 790 V and a low reverse leakage current.

Efficient and Robust Video Object Segmentation Through Isogenous Memory Sampling and Frame Relation Mining.

Recently, memory-based methods have achieved remarkable progress in video object segmentation. However, the segmentation performance is still limited by error accumulation and redundant memory, primarily because of 1) the semantic gap caused by similarity matching and memory reading via heterogeneous key-value encoding; 2) the continuously growing and inaccurate memory through directly storing unreliable predictions of all previous frames. To address these issues, we propose an efficient, effective, and robust segmentation method based on Isogenous Memory Sampling and Frame-Relation mining (IMSFR).

Enhanced soft magnetic properties and high-frequency stability of FeNiMo powder cores by coating SiO insulation layer.

FeNiMo/SiO powder cores were prepared using the sol-gel method. Tetraethyl orthosilicate (TEOS) was added to produce an amorphous SiO coating outside the FeNiMo particles to form a core-shell structure. The thickness of the SiO layer was designed by varying the concentration of TEOS, and the optimized permeability and magnetic loss of the powder core could achieve 78.

The Development of a Competency Assessment Standard for General Practitioners in China.

This paper describes the development of a competency assessment standard for General Practitioners in Shenzhen, China. The standard is to be used for developing and delivering the training curriculum for General Practitioners and to enable rigorous assessment of the mastery of the standards by GP trainees. The requirement for the training of General Practitioners in China is mandated by government policy requires an international standard curriculum to meet the needs of patients and the community.
