タイトル: A New Small-Sized Species of Orobdella (Hirudinea: Erpobdelliformes: Orobdellidae) from Mount Hehuan, Central Taiwan著者: Nakano, Takafumi; Lai, Yi-Te抄録: A small-type quadrannulate leech species of Orobdella Oka, 1895, O. minima sp. nov., from Mt. Hehuan in central Taiwan is described. Phylogenetic analyses using nuclear 18S rRNA, 28S rRNA, histone H3, mitochondrial cytochrome c oxidase subunit I, [Cys]tRNA, [Met]tRNA, 12S rRNA, [Val]tRNA, 16S rRNA, [Leu]tRNA and NADH dehydrogenase subunit 1 markers revealed that O. minima forms a clade with the middle-type quadrannulate O. ketagalan Nakano and Lai, 2012, which is endemic to northern Taiwan. This clade was sister to the other Taiwanese middle-type quadrannulate O. meisai Nakano and Lai, 2017. Based on the phylogenetic relationships among the Taiwanese Orobdella, their morphological characteristics are briefly discussed in a phylogenetic context. A key to the three species of Orobdella endemic to Taiwan is also provi ...

タイトル: Neural network ensembles for band gap prediction著者: Masuda, Taichi; Tanabe, Katsuaki抄録: The band gap energy is a critical physical property that characterizes the optical and electronic properties of semiconductors and insulators. The density functional theory has been widely employed as a method for theoretical calculation of the band gap, but it underestimates the band gap compared to the experimental value. Additionally, the hybrid functionals or the GW method, which offers higher prediction accuracy, entails high computational costs. Therefore, there has been a growing interest in data-driven approaches utilizing machine learning to mitigate computational costs and enhance prediction accuracy. Here we propose neural network ensemble learning, utilizing experimentally measured band gaps as training set to achieve rapid and highly accurate band gap predictions. Previously, research had been conducted to predict the experimental values of band gaps using ensemble ...
