The jump-yip display of black-tailed prairie dogs (Cynomys ludovicianus) is contagious, spreading through a prairie dog town as 'the wave' through a stadium. Because contagious communication in primates serves to assess conspecific social awareness, we investigated whether instigators of jump-yip bouts adjusted their behaviour relative to the response of conspecifics recruited to display bouts....

It seems I am fighting a two-front war, besieged by three superb scholars. Professors Robert Delahunty and John Yoo,1 and Professor Michael Ramsey2 have authored bracing and challenging responses to Unleashing the Dogs of War (Unleashing).3 Though I have learned from these essays, their authors might say that I have not learned enough because I continue to adhere to the categorical theory’s cla...

Virtual reality is a hot research topic in computer science and the introduction of virtual roaming to the field of urban planning provides a new means for urban design. This paper analyzes the development, features and technology of virtual reality and the virtual city roaming and its applications and advantages in urban planning; then focus on key technologies and how to implement a real-time...

Echinococcosis is a major emerging zoonosis in central Asia. A cross-sectional study of dogs in four villages in rural Kyrgyzstan was undertaken to investigate the epidemiology and transmission of Echinococcus spp. A total of 466 dogs were examined by arecoline purgation for the presence of Echinococcus granulosus and E. multilocularis. In addition, a faecal sample from each dog was examined fo...

We propose a framework based on proactive server roaming to mitigate the effects of Denial-of-Service (DoS) attacks. The active server proactively changes its location within a pool of servers to defend against unpredictable and undetectable attacks. Only legitimate clients can follow the active server as it roams. We present algorithms that are secure, distributed, randomized, and adaptive for...

Wireless LAN Roaming enables users to be authenticated and authorized for access networks at various places they visit. The largest roaming federation today is probably eduroam developed research education institutions. There have been some projects developing federations public wireless services as well. Since the introduction of Next Generation Hotspot concept, need interconnect these has eme...
