A little more than a year ago, we published an editorial calling for papers describing research on human subjects (1). Research on human subjects is becoming more feasible because of advances in methodology, and investigations on human subjects are needed to advance the areas of human physiology and disease covered by the Journal. Patient-oriented research in particular is often perceived as be...

speci cation. Individuals acquainted with the expected operation of a sequence of microcode can often identify errors in symbolic expressions easily because they manifest themselves as unusual looking results. The implication of this discovery is that the mere symbolic simulation of microcode is nearly as valuable as full formal veri cation in many situations. An early study of symbolic simulat...

Energy management systems are focused to achieve efficient electricity control in smart grid systems. In order to achieve the effective systems, various functions such as sensing mechanisms, control mechanisms, management mechanisms and user interface mechanisms are required. In this paper, we employ Arduino micro-computer as basic field devices and use virtual private server services for cloud...

Extreme energy photons are expected to be a minor component of the ultra high energy cosmic rays. Nevertheless, they are the carriers of very important astrophysical information related to the origin and propagation of such ultra energetic particles. JEM-EUSO is an orbital fluorescence telescope intended to observe the highest energy component of the cosmic rays, including photons and neutrinos...

To take up the challenge of understanding origin ultra-high-energy cosmic rays (UHECRs), new observational means appear necessary. The JEM-EUSO Collaboration has undertaken to open space road UHECR studies. For more than a decade, it been developing realistic program measure UHECRs from with unprecedented aperture, together complementary scientific objectives in broader multidisciplinary contex...
