Traditionally users subscribe to RSS feeds of interest using an RSS feed reader. The RSS feed reader periodically polls the subscribed feeds for updates or items to be displayed to the user. Many RSS feeds usually pertain to a single news source or blog. Others may aggregate various feeds usually on some topic and produce a single RSS feed. Middleware publishsubscribe systems allow users to sub...

The two open-ended frontiers in radio astronomy instrumentation are collecting area and field of view. Greater collecting area translates directly into greater sensitivity while increased field of view increases observing efficiency and makes feasible new areas of science, such as searches for transient radio sources, rare types of pulsars, and surveys of large portions of our Galaxy and of the...

The use of fermented liquid feeds in monogastric animal nutrition is regarded as one of the biosafe methods of animal production. This paper examines bacterial fermentation of feed substrates for production of fermented liquid feeds for pigs and moist feeds for poultry. Emphasis is placed on the interplay of factors affecting feed fermentation and their relationship to feed quality. The resista...

Effective responses to emergency situations require accessing both information that is known ahead of time and information from emergent sources. Whereas emergency providers have succeeded in formalizing acquisition and distribution of information from pre-existing sources, emergent and unconventional sources remain a challenge, especially in the context of rapid system-of-systems integration. ...

olarizing cells must first pick a direction. The external cues that guide this choice are obvious: bud scars or mating partners for budding yeast, and chemoattractant gradients for Dictyostelium and neutrophils. But polarization still occurs, albeit in a random direction, when these cues are either removed or made uniform. Now, Roland Wedlich-Soldner, Rong Li (Harvard Medical School, Boston, MA...

The expansion of the World Wide Web has led to a chaotic state where the users of the internet have to face and overcome the major problem of discovering information. For the solution of this problem, many mechanisms were created based on crawlers who are browsing the www and downloading pages. In this paper we describe “advaRSS” crawling mechanism which intends to be the base utility for syste...
