In recent years significant work has been undertaken by both national and local government agencies to protect critical data and infrastructures from cyber attacks. As a result, many Homeland Security solutions have been newly developed and deployed, requiring the design of new computer systems technologies, as well as techniques allowing security procedures to be executed on many different are...

Tibetans are often imagined as authentic, pure, and geographically undifferentiated, but Tibetan identity formation is, in fact, varied and deeply inflected by national location and transnational trajectories. In this paper I examine the frictions of encounter between three groups of Tibetans who arrived in the USA around the same time, but who differ in their relationships to the homeland. The...

From the second half of the 19th century up to modern times, the tremendous contribution of Italian chemists to the development of science resulted in the discovery of a number of innovative chemical transformations. These reactions were subsequently christened according to their inventors' name and so entered into the organic chemistry portfolio of "named organic reactions". As these discoveri...

in this paper, the writers try to compare two authors, the iranian leftist, bozorg alavi (1904-1997) and the polish joseph conrad (1857-1924). although these two writers have different attitudes to socialism and the question of revolution, both share romantic idealism and a tragic sense of personal and social life. moreover, they both are precursors of modernist novel in their countries, and sh...

I magine a software assistant agent (AA) that proactively provides relevant concise personalized information to an analyst or first responder and collaborates with other AAs to share knowledge and arrange person-to-person contact. The following descriptive scenario provides an example application of this concept. A report of an explosion at a chemical plant is received by a homeland security (H...

charged with protecting us from lurking outside dangers. What ensues is either smoldering conflict to attrition or large-scale open warfare. Treatments have generally been disappointing. Autoimmune phenomena are sometimes consequences of both autologous and allogeneic hematopoietic cell transplantation (HCT). So, why would one consider treating autoimmune diseases with HCT? Serendipity can fuel...
