タイトル: Elevated Serum Growth Differentiation Factor 15 Levels as a Potential Biomarker of the Efficacy of Imeglimin in Individuals With Type 2 Diabetes Mellitus: An Exploratory Study著者: Wada, Naoki; Murakami, Takaaki; Fauzi, Muhammad; Sakaki, Kentaro; Oshima, Shinobu; Shimada, Yoshihito; Asai, Kanae; Oshima, Ayako; Nomura, Satoko; Joo, Erina; Mori, Michiko; Fujiwara, Ryoko; Shide, Kenichiro; Wada, Keiko; Yabe, Daisuke; Inagaki, Nobuya; Harada, Norio抄録: Background: The aim of the present study was to conduct a prospective observational study to explore the effects of imeglimin on systemic energy metabolism/body composition and to identify potential mitochondria-related biomarkers of the efficacy of the drug in clinical settings. Methods: In this prospective observational study, 16 participants with type 2 diabetes mellitus in the diabetes clinic of Kyoto University Hospital were enrolled. Individuals were started on imeglimin as monotherapy or add-on therapy. Results: Aft ...

タイトル: Diffraction modelling of a 2023 March 5 stellar occultation by subkilometer-sized asteroid (98943) 2001 CC21著者: Arimatsu, Ko; Yoshida, Fumi; Hayamizu, Tsutomu; Ida, Miyoshi; Hashimoto, L, George; Abe, Takashi; Akitaya, Hiroshi; Aratani, Akari; Fukuda, Hidekazu; Fujita, Yasuhide; Fujiwara, Takao; Horikawa, Toshihiro; Iihoshi, Tamio; Imamura, Kazuyoshi; Imazawa, Ryo; Kasebe, Hisashi; Kawasaki, Ryosuke; Kishimoto, Hiroshi; Mishima, Kazuhisa; Miyachi, Machiko; Mizutani, Masanori; Nakajima, Maya; Nakatani, Hiroyoshi; Okamura, Kazuhiko; Okanobu, Misaki; Okuda, Masataka; Suzuki, Yuji; Tatsumi, Naoto; Uno, Masafumi; Yamamura, Hidehito; Yasue, Mikoto; Yoshihara, Hideki; Hirabayashi, Masatoshi; Yoshikawa, Makoto抄録: We present an analysis of a stellar occultation event caused by a near-Earth asteroid (98943) 2001 CC21, an upcoming flyby target in the Hayabusa2 extended mission, on 2023 March 5. To determine the asteroid’s shape from diffraction-affected light curves accu ...

タイトル: Cubic fourfolds with eleven cusps and a related moduli space著者: MUKAI, Shigeru抄録: First we construct a cubic 4-fold whose singularities are 11 cusps and which has an action of the Mathieu group

タイトル: Application of gravity recovery and climate experiment data and ensemble modeling to assess saltwater intrusion in the Miandoab coastal aquifer, Iran, under climate change著者: Nourani, Vahid; Paknezhad, Nardin Jabbarian; Wen, Zhang; Kantoush, Sameh Ahmed抄録: Study region: The Miandoab aquifer, northwest of Iran, which is located in a sub basin of the Urmia Lake. Study focus: To model the groundwater (GW) quantity and quality, shallow learning (Feed Forward Neural Network (FFNN), Adaptive neuro fuzzy inference system (ANFIS), Support Vector Regression (SVR)), their ensemble and deep learning models were applied. Projections by General Circulation Models (GCMs) for the Shared Socio-economic Pathways (SSP585) scenario, after bias correction, and changes of the model inputs including Normalized Difference Vegetation Index (NDVI), Gravity Recovery and Climate Experiment (GRACE), GRACE Follow-On (GRACE-FO) and GW level (GWL) obtained via Markov Chain model were employed f ...

タイトル: Effect of process parameters on woody biomass fractionation in a methanol/water mixture in a semi-flow reactor著者: Yao, Yilin; Minami, Eiji; Kawamoto, Haruo抄録: The degradation of woody biomass in methanol/water mixtures at elevated temperatures and pressures is a promising candidate for chemical production from renewable resources, combining the wood-degrading ability of water with the product-dissolving capacity of methanol. However, the effects of water and methanol on wood degradation remain unclear. In the present study, the effect of process parameters on the degradation of Japanese cedar in methanol/water at 270 ℃ and 10-30 MPa was investigated using a semi-flow reactor in which pressure and temperature can be controlled independently. At 270 ℃, hemicelluloses were degraded and solubilized more preferentially at 10 MPa, but delignification was more preferred at 20 and 30 MPa. In the resulting products, methylation of coniferyl alcohol from lignin and meth ...

タイトル: Mn-Based Transition Metal Oxide Positive Electrode for K-Ion Battery Using an FSA-based Ionic Liquid Electrolyte著者: Jiao, Kai; Yamamoto, Takayuki; Kiuchi, Hisao; Zhao, Haochong; Nohira, Toshiyuki抄録: Layered Mn-based transition metal oxides have gained interest as positive electrode materials for K-ion batteries due to their high capacity, excellent structural stability, and abundant resources. However, their practical utility is significantly hindered by insufficient electrochemical performances during operations. This study reports the successful synthesis of P3-K₀.₄₆MnO₂ via the solid-state method and investigates its charge–discharge behavior as a positive electrode working in an FSA-based (FSA= bis(fluorosulfonyl)amide) ionic liquid electrolyte at 298 K. The K₀.₄₆MnO₂ electrode demonstrates superior performance compared to previously reported KₓMnO₂ counterparts, delivering a reversible discharge capacity of about 100 mAh g⁻¹ at a curr ...

タイトル: Note on the summational invariant and corresponding local Maxwellian for the Enskog equation著者: Takata, Shigeru; Takahashi, Aoto抄録: The summational invariant and the corresponding local Maxwellian that are compatible with the Enskog equation are discussed, with special interest in the presence of a boundary. The local Maxwellian corresponding to the summational invariant is restrictive compared to the case of the Boltzmann equation in the sense that a radial flow and time-dependent temperature are forbidden. However, a rigid body rotation with a constant angular velocity is admitted as in the case of the Boltzmann equation. The influence of the presence of a boundary is also discussed in simple situations.
