In a world where technology advances, it is important that the human-computer interface follows in the same pace, to maximize the user experience. This means that when the machines become more powerful and the services become more comprehensive, it is important that they still are adapted to the users. In the web browsing world, a concept called infinite-scroll has become popular when trying to...

Abnormal electrical activity from the boundaries of ischemic cardiac tissue is recognized as one of the major causes in generation of ischemia-reperfusion arrhythmias. Here we present theoretical analysis of the waves of electrical activity that can rise on the boundary of cardiac cell network upon its recovery from ischaemia-like conditions. The main factors included in our analysis are macros...

Rotating spiral waves are observed in a variety of physical, chemical, and biological settings including the Belousov-Zhabotinsky (BZ) reaction, thermal convection in a thin fluid layer, slime mold on a nutrient-supplied medium, and waves of electrical activity in heart tissue [1,2]. While much attention has been devoted to spiral waves in two dimensions, there has also been increasing interest...

A new mechanical supercharger-a low compression ratio scroll compressor was introduced in this paper, including the principle, scroll geometry, suction volume, inner compression ratio, etc. Then the advantages of the scroll supercharger were pointed out compared with other superchargers. After some concrete design considerations, a prototype was made and the performance tests showed the results...

We examined the strengths and weaknesses of three diverse scroll control modalities for photo browsing on personal digital assistants (PDAs). This exploration covered nine alternatives in a design space that consisted of three visual interfaces and three control modalities. The three interfaces were a traditional thumbnail layout, a layout that placed a single picture on the screen at a time, a...

We develop a numerical approach based on our recent analytical model of fiber structure in the left ventricle of the human heart. A special curvilinear coordinate system is proposed to analytically include realistic ventricular shape and myofiber directions. With this anatomical model, electrophysiological simulations can be performed on a rectangular coordinate grid. We apply our method to stu...
