Harmonic Angular Mapping Method for Binary Microlensing Grid Search
Kansuke Nunota
Searching for binary-lens microlensing solutions is computationally demanding because of the complex parameter space and the large number of trial models required. We present an al…
Peripheral prototypical contrastive loss for supervised medical image segmentation
Takuro Shimaya, Ryosaku Shino, Masahiro Saiko
Robust segmentation of biomedical images remains challenging primarily due to ill-defined object boundaries. Although several loss functions have recently been proposed to enhance…
Smectic-like bundle formation of planktonic bacteria upon nutrient starvation
Takuro Shimaya, Kazumasa A. Takeuchi
Bacteria aggregate through various intercellular interactions to build biofilms, but the effect of environmental changes thereupon remains largely unexplored. Here, by using an exp…
Emergence of bacterial glass
Hisay Lama, Masahiro J. Yamamoto, Yujiro Furuta +2
Densely packed, motile bacteria can adopt collective states not seen in conventional, passive materials. These states remain in many ways mysterious, and their physical characteriz…
Tilt-induced polar order and topological defects in growing bacterial populations
Takuro Shimaya, Kazumasa A. Takeuchi
Rod-shaped bacteria, such as Escherichia coli, commonly live forming mounded colonies. They initially grow two-dimensionally on a surface and finally achieve three-dimensional grow…
Scale invariance of cell size fluctuations in starving bacteria
Takuro Shimaya, Reiko Okura, Yuichi Wakamoto +1
In stable environments, cell size fluctuations are thought to be governed by simple physical principles, as suggested by recent findings of scaling properties. Here, by developing…
Lane formation and critical coarsening in a model of bacterial competition
Takuro Shimaya, Kazumasa A. Takeuchi
We study competition of two non-motile bacterial strains in a three-dimensional channel numerically, and analyze how their configuration evolves in space and time. We construct a l…
