Crosstalk of cancer stemness-neutrophils in outcome of intracranial germ cell tumors [PDF]

open access: yesFrontiers in Immunology
BackgroundIntracranial germ cell tumors (iGCTs) are categorized into germinomas (GEs) and non-germinomatous germ cell tumors (NGGCTs), which show divergent clinical outcomes with GEs having a significantly more favorable prognosis.

Soft-Switching Resonant Conversion with IGCT [PDF]

open access: yes2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
In the area of medium voltage DC-DC conversion, series resonant converter is an attractive topology for implementation of the solid state DC transformer. Applying integrated gate controlled thyristor as a switch, it is possible to obtain very low conduction losses, while greatly lowering the switching losses by proper use of this converter topology ...
