Discrimination of time-dependent inflow properties with a cooperative dynamical system
Hiroshi Ueno, Tatsuaki Tsuruyama, Bogdan Nowakowski +2
Many physical, chemical and biological systems exhibit a cooperative or sigmoidal response with respect to the input. In biochemistry, such behavior is called an allosteric effect.…
Roughening dynamics of spontaneous radial imbibition
Yong-Jun Chen, Kenichi Yoshikawa
We performed an experimental observation on the spontaneous imbibition of water in a porous media in a radial Hele-Shaw cell and confirmed Washburn's law, where r is distance and t…
Anomalous roughening of forced radial imbibition in a porous medium
Yong-Jun Chen, Shun Watanabe, Kenichi Yoshikawa
We report forced radial imbibition of water in a porous medium in a Hele-Shaw cell. Washburn's law is confirmed in our experiment. Radial imbibition follows scaling dynamics and sh…
Self-organized Archimedean Spiral Pattern: Regular Bundling of Fullerene through Solvent Evaporation
Yong-Jun Chen, Kosuke Suzuki, Hitoshi Mahara +2
We report the spontaneous generation of an Archimedean spiral pattern of fullerene via the evaporation of solvent. The self-organized spiral pattern exhibited equi-spacing on the o…
Anomalous Roughening of Curvature-Driven Growth With a Variable Interface Window
Yong-Jun Chen, Yuko Nagamine, Tomohiko Yamaguchi +1
We studied the curvature-driven roughening of a disk domain pattern with a variable interface window. The relaxation of interface is driven by negative surface tension . When a dom…
Dynamic Labyrinthine Pattern in an Active Liquid Film
Yong-Jun Chen, Yuko Nagamine, Kenichi Yoshikawa
We report the generation of a dynamic labyrinthine pattern in an active alcohol film. A dynamic labyrinthine pattern is formed along the contact line of air/pentanol/aqueous three…
