Achieving Portable andE cient Parallel

SUMMARY With the availability of Computational Grids, new kinds of applications are emerging. They raise the problem of how to program them on such computing systems. In this paper, we advocate a programming model based on a combination of parallel and distributed programming models. Compared to previous approaches, this work aims at bringing SPMD programming into CORBA in a portable way. For e...

Potent anti-platelet constituents from Centaurea iberica.

New naturally occurring nitrogenous compounds 1 and 2, along with a new dimeric lignan glucoside 3, have been isolated from the ethyl acetate soluble fraction of Centaurea iberica. Their structures have been elucidated through spectroscopic techniques. All the isolated compounds showed significant platelet aggregation inhibition.

Kamiokande and Super-Kami ok ande

Neutrino astrophysics has begun in 1987 when Kamiokande observ ed the neutrino burst from a sup erno va SN1987A. Kamiok ande succeeded to observ e solar neutrinos and demonstrated at the rst time that the observ ed neutrinos are coming from the direction of the sun and con rmed the long standing solar neutrino problem. The atmospheric neutrino anomaly was rst pointed out by the Kamiok ande expe...

Traversals of Object Structures : Speci cation andE cient Implementation

We present a new approach, called strategies, to the task of traversing object structures. In our approach traversals are deened using a high-level directed graph description, which is compiled into a dynamic road map to assist run-time traversals. The complexity of the compilation algorithm is polynomial in the size of the strategy graph and the class graph of the given application. The implem...
