Commander of the Faithful: The Life and Times of Emir Abd el-Kader: A Story of True Jihad

Since September 11, 2001, Muslims have been stereotyped and the message and image of Islam have been tarnished. Self-proclaimed leaders have given new and twisted meanings to the message of Islam. Explanations of complex issues have been reduced to sound bites on television. No issue has been in this regard more profaned than jihad, a sacred term for Muslims, There is no dearth of explanations ...

Role of abd-A and Abd-B in Development of Abdominal Epithelia Breaks Posterior Prevalence Rule

Hox genes that determine anteroposterior body axis formation in all bilaterians are often found to have partially overlapping expression pattern. Since posterior genes dominate over anterior Hox genes in the region of co-expression, the anterior Hox genes are thought to have no function in such regions. In this study we show that two Hox genes have distinct and essential functions in the same c...

Optimal Synchronization of ABD Networks

We present in this paper a simple and e cient synchronizer algorithm for Asynchronous Bounded Delay Networks. In these networks each processor has a local clock, and the message delay is bounded by a known constant. The algorithm improves on an earlier synchronizer for this network model, presented by Chou et al.[CCGZ90]. Moreover, using a mathematical model for this type of synchronizer, we sh...

The Parallel Solution of ABD

Many commonly used numerical methods for the solution of Boundary Value Problems (BVPs) for Ordinary Di erential Equations (ODEs) contain signi cant components that can be parallelized easily, and recent investigations have shown that substantial speedups are attainable on machines with a modest number of processors. However, a stage in most of these methods is the numerical solution of an Almo...
