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...

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...

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 MU‘TAZILITE QĀDĪ ‘ABD AL-JABBĀR ON THE DENOTATION OF MIRACLES

This article examines the Mu‘tazilite Qādī ‘Abd al-Jabbār’s views on the denotation of miracles according to his own particular methodology. Despite his acceptance of the celebrated method of the theologians in the denotation of miracles with respect to the authenticity of prophets, i.e., resorting to divine wisdom, Qādī ‘Abd al-Jabbār instead proposed the issue within the structure of conven...
