Heterogeneous network computing enables the development of a single complex application using a distributed network of possibly dissimilar machines. While heterogeneous networks promise cost-eeective compute cycles, almost no software is available to aid in the design and implementation of their applications. In this paper, we couple the Zoom representation, designed to facilitate development o...

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have diierent operating systems and data formats and are ...

This paper studies the notions of conceptual grounding and explanation (which includes notion mathematical explanation), with an aim clarifying links between them. On one hand, it analyses complex examples these two that bring to fore features are easily overlooked otherwise. other provides a formal framework for modeling both explanation, based on concept proof. Inspiration analogies drawn rec...

There are two ways eukaryotes double number of chromosomes: (1) whole genome duplication (polyploidy), in which all nuclear DNA is replicated, and (2) karyotypic fission (pseudopolyploidy), in which all chromosomes are physically bifurcated. We contrast polyploidy with pseudopolyploidy, highlighting when it is crucial to look at genetic vs. genomic levels. We review history of pseudopolyploidy,...
