The nature of hot electron electroluminescence (EL) in AlGaN/GaN high electron mobility transistors is studied and attributed to Bremsstrahlung. The spectral distribution has been corrected, for the first time, for interference effects due to the multilayered device structure, and this was shown to be crucial for the correct interpretation of the data,(More)
OBJECTIVE To investigate anti-neurofascin 155 (NF155) antibody-positive chronic inflammatory demyelinating polyneuropathy (CIDP). METHODS Sera from 50 consecutive CIDP patients diagnosed in our clinic, 32 patients with multiple sclerosis, 40 patients with other neuropathies including 26 with Guillain-Barré syndrome (GBS)/Fisher syndrome, and 30 healthy(More)
Tacrolimus is an immunosuppressive drug used to prevent acute rejection following organ transplantation and to treat autoimmune disease. Tacrolimus is usually prescribed in such situation at a dose of 3.0 mg/day. Pneumocystis pneumonia induced by this dose of tacrolimus has been reported in many cases; however, we encountered a rare case of Pneumocystis(More)
We report a patient with gastric carcinoma successfully treated with TS-1/CDDP as a neoadjuvant chemotherapy. The patient was a 72-year-old man who had suffered from general malaise with severe anemia and was diagnosed as type 2 carcinoma, having bulky N2, with suspected invasion of the pancreas. TS-1 (100 mg/day) was administered orally every day for 21(More)
BACKGROUND Lung adenocarcinoma is often composed of a complex and heterogeneous mixture of histological subtypes. Invasive adenocarcinomas are now classified by their predominant pattern, using the comprehensive histological subtyping of the International Association for the Study of Lung Cancer (IASLC), the American Thoracic Society (ATS), and the European(More)
The purpose of this paper is to construct an impression evaluation model for button sounds generated when users press the buttons on car audio systems using a neural network. The dynamic characteristics of 11 kinds of button sounds obtained by their wavelet transform frequencies. Their sound pressure values are fed into the neural network model inputs. The(More)
Non-small cell lung cancer (NSCLC) patients with squamous cell carcinoma (SCC) histology have limited chemotherapeutic options. Treatment with S-1 combined with carboplatin (CBDCA) has been shown to provide a significant survival benefit in SCC patients compared with treatment with combined CBDCA and paclitaxel. The aim of the present study was to(More)
