Current IaaS (infrastructure as a service) cloud service may not satisfy communication QoS (quality of service) requirements of delay‐sensitive network applications, if there is a significant physical distance between a server of the network application (NetApp server) at a data center and its network application clients (NetApp clients). In order...

Cancer cells collectively form a large-scale structure for their growth. In this article, we report that HeLa cells, epithelial-like human cervical cancer cells, aggressively migrate on Matrigel and form a large-scale structure in a cell-density-dependent manner. To explain the experimental results, we develop a simple model in which cells interact...

In IaaS cloud services, QoS of network applications (NW-Apps) may degrade due to location factors such as significant distance between a server-side application (server) of a NW-App at a data center and a client-side application (client) of the NW-App at a client terminal. In order to shorten the distance and to improve the QoS, server migration se...

Intercellular Ca(2+) waves are commonly observed in many cell types. In non-excitable cells, intercellular Ca(2+) waves are mediated by gap junctional diffusion of a Ca(2+) mobilizing messenger such as IP(3).
