Measurement of low-energy antiproton detection efficiency in BESS below 1 GeV

An accelerator experiment was performed using a low-energy antiproton beam to measure antiproton detection efficiency of BESS, a balloon-borne spectrometer with a superconducting solenoid. Measured efficiencies showed good agreement with calculated ones derived from the BESS Monte Carlo simulation based on GEANT/GHEISHA. With detailed verification of the BESS simulation, the relative systematic error of detection efficiency derived from the BESS simulation has been determined to be $\pm$5%, compared with the previous estimation of $\pm$15% which was the dominant uncertainty for measurements of cosmic-ray antiproton flux.Comment: 13 pages, 7 figure

Precise Measurement of Cosmic-Ray Proton and Helium Spectra with the BESS Spectrometer

We report cosmic-ray proton and helium spectra in energy ranges of 1 to 120 GeV and 1 to 54 GeV/nucleon, respectively, measured by a balloon flight of the BESS spectrometer in 1998. The magnetic-rigidity of the cosmic-rays was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 Tesla. Those spectra were determined within overall uncertainties of +-5 % for protons and +- 10 % for helium nuclei including statistical and systematic errors.Comment: 12 pages, 4 figure

キャンパスワイドデータ集約基盤の構築とデータ解析の研究

本論文では、専修大学データサイエンス研究助成により支援を受けた研究プロジェクトの2年間の活動について報告する。本研究プロジェクトは、情報科学研究所内での呼びかけから始まり、学部の枠を超えたバックグラウンドの異なる教員が、得意とするところをそれぞれに発揮して行われたものである。2年間を通して、実に多くの議論を重ねてきたが、その中で得られた電力需要予測・情報集約基盤の構築・食堂混雑緩和の取り組み・混雑状況の可視化といった成果とともに、明確な成果には至らなかった活動についても述べる。This paper reports on two-year activities of our research project supported by the Senshu University data science research grant. The research project started with a call in Institute of Information Science and involved researchers with different research backgrounds. We brought our own disciplines and strengths to proceed the project. We describe our outcomes including electricity demand forecasting, building data foundation, congestion mitigation of restaurant, and visualization of congestion, as well as trials without clear outcomes.departmental bulletin pape

Comparisons of Postoperative Complications and Nutritional Status After Proximal Laparoscopic Gastrectomy with Esophagogastrostomy and Double-Tract Reconstruction

[Background] The purpose of this study was to compare postoperative complications and nutritional status between esophagogastrostomy and double-tract reconstruction in patients who underwent laparoscopic proximal gastrectomy, and assess the advantages of both surgical procedures. [Methods] Between 2010 and 2018, 47 cases underwent proximal gastrectomy with esophagogastrostomy (n = 23) or double-tract reconstruction (n = 24) at our institution for the treatment of clinical T1N0 adenocarcinoma located in the upper third of the stomach. Patient clinical characteristics, short-term outcomes, nutrition status, and skeletal muscle index were compared among the two groups. [Results] There was no significant difference between esophagogastrostomy and double-tract reconstruction in terms of operation time, blood loss, and length of postoperative hospital stay. Reflux symptoms and anastomotic stenosis were significantly higher in the esophagogastrostomy group compared with the double-tract reconstruction group (P < 0.001 and P = 0.004, respectively). There was no significant difference in anastomotic leakage, surgical site infection, and pancreatic fistula. For the nutritional status, the decrease rate of cholinesterase was significantly higher in the esophagogastrostomy group compared with the double-tract reconstruction group at 6 months (P = 0.008) There was no significant difference in the decrease rate of skeletal muscle mass index at 1 year after surgery. [Conclusion] Compared with esophagogastrostomy, double-tract reconstruction tends to have better short-term nutritional status and postoperative outcomes in terms of preventing the occurrence of gastroesophageal reflux and anastomosis stenosis. These findings suggest that double-tract reconstruction may be a useful method in laparoscopic proximal gastrectomy.journal articl
