We have characterized several dynamic aspects of a simple chemical system capable of self-movement: An oil droplet in water system. We focused on spontaneous mode switching and collective behavior of droplets as emergent properties of the system. Droplets demonstrated spontaneous mode switching by changing speed, direction and acceleration over time, and(More)
This paper presents a detailed characterization of the trajectory of a single housefly freely walking in a square cage. The trajectory of the fly is recorded and transformed into time series, which is fully analyzed by the method of AR model. A main discovery is that the fly switches the styles of motion from the low dimensional regular pattern to the(More)
This paper presents a detailed characterization of the trajectory of a single housefly with free range of a square cage. The trajectory of the fly was recorded and transformed into a time series, which was fully analyzed using an autoregressive model, which describes a stationary time series by a linear regression of prior state values with the white noise.(More)
OBJECTIVE This study was undertaken to investigate the feasibility and accuracy of determination of stroke volume and cardiac output by calculating transmitral flow volume using the flow convergence region method in patients with mitral stenosis. PATIENTS AND INTERVENTIONS Fifty-six patients with rheumatic mitral stenosis were studied using imaging and(More)
