We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.

This paper is concerned with constraints on the interpretation of pronominal anaphora, in particular Condition B effects. It aims to contribute to a particular approach, initiated by Reinhart (1983) and further developed by Heim (1998), Fox (2000), Büring (2005b), Reinhart (2006), and Reuland (2008). It proposes a modification of Reinhart’s Interface Rule, and argues that the resulting theory c...

Since decades, basic-block (BB) graphs are the state-of-the-art means for representing programs in advanced industrial compiler environments. The usual justi cation for introducing the intermediate BB-structures in the program representation is performance: analyses on BB-graphs are generally assumed to outperform their counterparts on single-instruction (SI ) graphs, which, undoubtedly, are co...
