Computational grid computing has emerged as one of the most promising research areas in high performance and distributed computing. The ability to allocate large numbers of resources for a parallel application with a greatly reduced cost makes the concept grid computing highly appealing. The heterogeneous nature of a grid creates a complex application environment; the nature of faults within th...

Non-Markovian reduced dynamics of an open system is investigated. In the case the initial state of the reservoir is the vacuum state, an approximation is introduced which makes possible to construct a reduced dynamics which is completely positive.

California is a leader among states in its efforts to cut greenhouse gas emissions. Under the California Global Warming Solutions Act of 2006 (Assembly Bill 32), the state has set itself on a course to reduce its greenhouse gas emissions to 1990 levels by the year 2020. In addition to its cap-and-trade program, California aims to accomplish this objective via a large assortment of complementary...

A new method to deal with reduced dynamics of open systems by means of the Schrödinger equation is presented. It allows one to consider the reduced time evolution for correlated and uncorrelated initial conditions.

Software services offer many opportunities like reduced cost for IT infrastructure. They also introduce new risks, for example the clients lose control over their data. While data can be secured against external threats using standard techniques, the service providers themselves have to be trusted to ensure privacy. In this paper, we examine methods that can increase the level of privacy a serv...

Mutation analysis is a fault-based testing technique that uses mutation operators to introduce small changes into a program or specification, producing mutants, and then chooses test cases to distinguish the mutants from the original. Mutation operators differ in the coverage they get. They also differ in the number of mutants they generate. Consequently, selecting mutation operators is an impo...

Studies of the furious and paralytic forms of canine rabies at the early stage of disease have shown a more rapid viral colonization of the cerebral hemispheres in the furious form, as measured by viral antigen within neuronal cell bodies and viral RNA levels. Measurement of cellular processes separate from neuronal cell body provides a visual record of the spread of rabies virus which occurs a...

• Reduced lignin content in perennial crops has been sought as a means to improve biomass processability for paper and biofuels production, but it is unclear how this could affect wood properties and tree form. • Here, we studied a nontransgenic control and 14 transgenic events containing an antisense 4-coumarate:coenzyme A ligase (4CL) to discern the consequences of lignin reduction in poplar ...
