چکیده

Recent measurements of the CR p̄ flux have been shown to pose a problem for conventional propagation models. In particular, models consistent with secondary/primary nuclei ratio in CR produce too few p̄’s, while matching the ratio and the p̄ flux requires ad hoc assumptions. This may indicate an additional local CR component or new phenomena in CR propagation in the Galaxy. We discuss several possibilities which may cause this problem.

The Science of Pamela Space Mission

Many different mechanisms can contribute to antiprotons and positrons production, ranging from conventional reactions up to exotic processes like neu-tralino annihilation. The open problems are so fundamental (i.e.: is the universe symmetric in matter and antimatter ?) that experiments in this field will probably be of the greatest interest in the next years. Here we will summarize the present ...

The Journal of Nutrition Symposium: Caloric Restriction and Delayed Biological Aging in Humans Starving for Life: What Animal Studies Can and Cannot Tell Us about the Use of Caloric Restriction to Prolong Human Lifespan

Caloric restriction (CR) is the only experimental nongenetic paradigm known to increase lifespan. It has broad applicability and extends the life of most species through a retardation of aging. There is considerable interest in the use of CR in humans, and animal studies can potentially tell us about the impacts. In this article we highlight some of the things that animal studies can tell us ab...

Download Statistics - What Do They Tell Us?: The Example of Research Online, the Open Access Institutional Repository at the University of Wollongong, Australia

A study was undertaken of download and usage statistics for the institutional repository at the University of Wollongong, Australia, over the six-month period January-June 2006. The degree to which research output was made available, via open access, on Internet search engines was quantified. Google was identified as the primary access and referral point, generating 95.8% of the measurable full...
