This paper presents an overview of the ACESparallel software sysremand, in particular, an introduction to the EcliPSe layer of the system. The ACES system is a fault-tolerant, layered software system for heterogeneous-network based cluster computing. The EcliPSe toolkit, which resides on an upper layer, was constructed specifically for replication-based and domain-decomposition based simulation...

A light curve modelling and fitting program is presented for cataclysmic variable stars and related objects. It allows modelling of a three-dimensional disk in conjunction with the Roche-lobe filling secondary star, thus rendering it a very general tool for light curve analysis. Optimization of the solution is based on the maximumentropy algorithm. Some bench-mark tests are presented, and the g...

A two-step purification of pneumococcal eclipse complex is described, which uses sucrose gradient sedimentation followed by agarose gel permeation chromatography. Purified complex contains, in addition to donor DNA single strands, macromolecular material that can be labeled with methionine or leucine during development of competence. This material co-chromatographed with eclipse complex DNA on ...
