Enhanced radiosensitivity of head and neck cancer cells to proton therapy via hyperthermia-induced homologous recombination deficiency

Clinical and Translational Radiation Oncology
Background and purpose: Radiotherapy induces tumor cell killing by generating DNA double strand breaks (DSBs). The effectiveness of radiotherapy is significantly influenced by the repair of DSBs, which counteracts this lethal effect.

Proton irradiation impact on interface traps under Schottky contact in AlGaN/GaN heterostructure

AIP Advances, 2020
The effect of 3 MeV proton irradiation on interface traps under a Schottky contact in an AlGaN/GaN heterostructure has been investigated in this work. Utilizing the frequency-dependent conductance technique, the detailed information about interface traps

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Investigation of Proton Irradiation-Enhanced Device Performances in AlGaN/GaN HEMTs

IEEE Journal of the Electron Devices Society, 2022
We have studied the effects of proton irradiation on the AlGaN/GaN HEMTs with AlN buffer layer as well as conventional GaN buffer layer. It was found that a short time proton irradiation (~ 50 sec) can promote beneficial effects on device ...
