Tree-Like Features Formed on Photoelectrochemically etched n-GaN surfaces ―Revelation of threading dislocations in GaN―

Electrochemical etching behavior of n-type GaN films grown on sapphire has been studied under UV (λ=325 nm) light illumination. As the cases for photoelectrochemical etching of n-type GaAs and InP, three different features appear on etched n-GaN surfaces depending on current density for etching; a high density (10^10 cm^<-2>) of tree-like protrusions at a lower c-urrent density, a relatively flat surface at an intermediate current density, and peeling of the film from the substrate at a higher current density. From the shape and the density of tree-like protrusions, in addition to the analogy of these results with those for n-type GaAs and InP, it is reasonable to conclude that tree-like protrusions formed at a low current density are due to threading dislocations involved in n-GaN films. Thus, the photoelectrochemical etching is found to become a convenient method to detect dislocations in n-type III nitride materials

Predictors of the Response to Tolvaptan Therapy and Its Effect on Prognosis in Cirrhotic Patients with Ascites

Aims: The vasopressin V2 receptor antagonist, tolvaptan, has been reported to be effective in cirrhotic patients with ascites. Here, we evaluated predictors of the response to tolvaptan. Methods: A total of 97 patients with cirrhosis (60 males; median age, 63 years) who had been treated for ascites with oral tolvaptan were enrolled. Tolvaptan efficacy was defined as urine volume increase of ≥500 mL or a urine volume ≥2000 mL/day on the day following treatment. Normalization of the serum sodium (Na) level after 1 week of treatment and the posttreatment survival rate was analyzed. Results: Tolvaptan therapy resulted in effective urination in 67% of patients. A multivariate analysis revealed that the blood urea nitrogen/creatinine (BUN/Cr) ratio and urinary Na/potassium (Na/K) ratio were predictive of the tolvaptan response (p <0.05). The serum Na level was 135 (121–145) mEq/L, and normal levels were recovered in 50.0% of the patients with an initial Na level of <135 mEq/L. The posttreatment survival rate was significantly higher in patients who responded to tolvaptan therapy (p <0.05). Conclusions: The combination of the initial BUN/Cr and urine Na/K ratios and a normalized serum Na level after 1 week was predictive of a favorable outcome to tolvaptan therapy

Status of 48Ca double beta decay search in CANDLES

We study a strategy to reduce veto-time in the search for neutrino-less double-beta decay (0υββ) with CANDLES-III system. We develop a new likelihood analysis and apply it to our new Run010 data. We show that we can increase the un-vetoed live-time by 11.8%. Thanks to this improvements, We expect to increase a limit on the life-time of 0υββ by a factor of three by analyzing both Run009 and Run010 data

The Japanese space gravitational wave antenna; DECIGO

DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future Japanese space gravitational wave antenna. DECIGO is expected to open a new window of observation for gravitational wave astronomy especially between 0.1 Hz and 10 Hz, revealing various mysteries of the universe such as dark energy, formation mechanism of supermassive black holes, and inflation of the universe. The pre-conceptual design of DECIGO consists of three drag-free spacecraft, whose relative displacements are measured by a differential Fabry– Perot Michelson interferometer. We plan to launch two missions, DECIGO pathfinder and pre- DECIGO first and finally DECIGO in 2024

センダイシ オヨビ ナトリシ デ シハンサレル トリ ヒキニク カラノ サルモネラ ノ ケンシュツ ホウコク

本研究では、宮城県で調査報告の少ない鳥ひき肉におけるサルモネラの汚染状況を調査した。その結果、市販される鶏ひき肉55.2％にサルモネラの汚染が確認された。この汚染レベルは、全国レベルに匹敵し、鶏の育成場所や鳥肉処理場、ミンチ加工処理、包装などが違えども、同程度の汚染がみられた。またムネ肉とモモ肉では、汚染には差が認められなかった。販売店舗としては調査した11店舗中10店舗の鳥ひき肉でサルモネラ汚染は認められたが、直接培養で検出されないなど、その汚染菌数は少ない。さらに冷蔵や加熱などの食品に認められる損傷菌に関しても、今回分離したサルモネラの37.5％が損傷菌である可能性がある。ここ宮城県仙台市および名取市で市販される鳥ひき肉からもサルモネラ菌の汚染が示されたことから、鳥ひき肉の調理や取り扱いにも十分注意することを強調したい
