Price fluctuation is a random walk and the resulting statistical distribution is Gaussian. This is the starting point of financial engineering to derive, for example, the Black-Sholes Formula for derivative prices. On the other hand, it is widely kno

We study the statistical nature of stock price fluctuation in the ultrafast stock trading system called the “arrowhead market”. The first stage of this “arrowhead market” was started in the beginning of January 2010 at Tokyo Security Exchange

When a camphor disk is placed close to a water surface, Marangoni convection occurs due to the surface tension gradient originating from the spatial distribution of camphor molecules at the water surface. We put plastic floats on the water surface to

A self-propelled motor driven by the enzymatic reaction of catalase adsorbed onto a filter paper floating on an aqueous solution of H2 O2 was used to study nonlinear behavior in the motor's motion. An increase in the concentration of H2 O2 resulted i

A series of physical double-network hydrogels is synthesized based on an amphiphilic triblock copolymer. The gel, which contains strong hydrophobic domains and sacrificial dynamic bonds of hydrogen bonds, is stiff and tough, and even stiffens in conc

Most studies on hydrogel swelling instability have been focused on a constrained boundary condition. In this paper, we studied the mechanical instability of a piece of disc-shaped hydrogel during free swelling. The fast swelling of the gel induces tw

We investigated the water-depth dependence of the self-motion of a camphor disk and camphor boat. With increasing water depth, the speed of motion of the camphor disk increased, but that of the camphor boat decreased in an annular one-dimensional sys

Oscillation in the metabolism of microorganisms often depends on the cell density, where each cell interacts through the mediator concentration(s) in its environment. Such bifurcation behavior indu...

The concept of self-propelled objects is important for the understanding of biological mobility, as well as for the development of autonomous devices in medicine and engineering. In this study, a simple self-propelled object, driven by a difference i
