タイトル: Systematic parameterizations of minimal models of microswimming著者: Walker J., Benjamin; Ishimoto, Kenta; Gaffney A., Eamonn抄録: Simple models are used throughout the physical sciences as a means of developing intuition, capturing phenomenology, and qualitatively reproducing observations. In studies of microswimming, simple force-dipole models are commonplace, arising generically as the leading-order, far-field descriptions of a range of complex biological and artificial swimmers. Though many of these swimmers are associated with intricate, time varying flow fields and changing shapes, we often turn to models with constant, averaged parameters for intuition, basic understanding, and back-of-the-envelope prediction. In this brief study, via an elementary multitimescale analysis, we examine whether the standard use of a priori-averaged parameters in minimal microswimmer models is justified, asking if their behavioural predictions qualitatively align with those of mode ...

タイトル: Decomposition of mechanical stress effect on the magnetic property of silicon steel sheet著者: Shimizu, H.; Marumo, Y.; Mishima, Y.; Matsuo, T.抄録: A principal stress decomposition method was examined and compared with the equivalent stress theory to evaluate the stress-dependent magnetic properties of nonoriented silicon steel. A physical magnetization model, the multidomain particle model, was used to simulate the stress dependence of the magnetic properties by applying mechanical stress in different directions relative to the magnetic field direction. Experimental and computational tests show that even though the principal stress decomposition method provides a reasonable evaluation of the stress-dependent properties in the stress direction, it fails to accurately predict the properties in the perpendicular direction. To improve the prediction accuracy, a modified decomposition method is proposed, which gives a reasonable evaluation of the stress dependence of BH ...

タイトル: Review: Monitoring of land cover changes and plant phenology by remote‐sensing in East Asia著者: Shin, Nagai; Saitoh, M., Taku; Takeuchi, Yayoi; Miura, Tomoaki; Aiba, Masahiro; Kurokawa, Hiroko; Onoda, Yusuke; Ichii, Kazuhito; Nasahara, Nishida, Kenlo; Suzuki, Rikie; Nakashizuka, Tohru; Muraoka, Hiroyuki抄録: To achieve a sustainable society and solve the problems caused by climate change and socioeconomic activities, it is necessary to monitor the spatial and temporal variability of ecosystem functions, services, and biodiversity at both regional and global scales. During the last decade, we have seen rapid and significant improvement in satellite and near-surface remote-sensing technologies. In this review, we describe how remote-sensing observations are being used to effectively evaluate the spatial and temporal variability of land use and cover types and of plant phenology in East Asia. We discuss the current status, uncertainties, problems, and future perspecti ...
