We report a new fabrication process to realize a slant field plate – a field plate in which the plate-to-channel distance gradually increases with the distance from the gate edge – using a multi-layer SiCN film. AlGaN/GaN HEMTs with several types

Tissue-specific gene deletion by the Cre-loxp system is a powerful tool to investigate the roles of specific genes. To determine the specificity and efficiency of the Cre-mediated recombination under the control of the human smooth muscle alpha-actin

BACKGROUND Hemodialysis (HD) patients are reported to show poor clinical outcomes after percutaneous coronary intervention (PCI) with sirolimus-eluting stent (SES) compared with non-HD patients and their long-term prognosis remains unclear. METHODS A

International audience; We report on the intrinsic responsivity of an asymmetric dual-grating-gate plasmonic detector over 100 kV/W at 200 GHz and 50 kV/W at 300 GHz measured at room temperature with zero source-drain bias. We demonstrate that broadb

In an OFDM system, it is possible to improve the symbol error rate degradation from the multipath by using an equalizer. However, received power of specific carriers drops down and carrier to noise ratio becomes lower for such carriers when an affect

A new process approach to realize a slant field plate — a field plate (FP) gradually separated from the semiconductor surface from the gate edge toward the drain — is reported. A multistep SiCN dielectric film is used to make a sloped sidewall in

This paper presents a new multiple hypothesis problem for spectrum sharing between primary users (PUs) and secondary users (SUs) with cognitive radio technique. The considered four hypotheses are as follows; the studied frequency band is vacant (hypo

We experimentally demonstrate the efficacy of using slant field plates (field plates with the plate-to-channel gap gradually increasing away from the gate edge) on the breakdown voltage. We develop a new fabrication process using a multi-step SiCN fi

In 193 cases autopsied between 1945 and 1980, all persons who had been intravascularly injected with Thorotrast in life, the authors found 131 malignant hepatic tumors, 20 liver cirrhoses, 6 myeloid leukemias, 4 erythroleukemias, 5 aplastic anemias,

An epidemiological follow-up study was conducted on 272 Thorotrast-administered war-wounded ex-servicemen to determine their status as of 31 December 1980, after a lapse of 35-43 yr from Thorotrast injection. In the 251 cases who had been intravascul
