Viruses infecting marine phytoplankton drive phytoplankton diversity, terminate blooms and shuttle genetic material. Assessments of the scale of viral impacts on trophic networks are, however, speculative. We investigated fluxes of DNA between host and virus during infection of the prasinophyte alga Micromonas pusilla by phycodnavirus MpV SP1. Under a light-dark regimen, viral genomes accumulat...

In this study we examined the effect of dopaminergic modulation on learning and memory. Parkinson's patients were tested 'on' versus 'off' dopaminergic medication, using a two-phase learning and transfer task. We found that dopaminergic medication was associated with impaired learning of an incrementally acquired concurrent discrimination task, while patients withdrawn from dopaminergic medicat...

We present a flexible non-parametric generative model for multigroup regression that detects latent common clusters of groups. The model is founded on techniques that are now considered standard in the statistical parameter estimation literature, namely, Dirichlet process(DP) and Generalized Linear Model (GLM), and therefore, we name it “Infinite MultiGroup Generalized Linear Models” (iMGGLM). ...

Many companies producing durable products, profit more from spares than the base parts. In a competitive and uncertain aftermarket, an Original Equipment Manufacturer (OEM) can benefit from Game Theory to manage spare parts inventories. We study the spare parts inventory game as an N-person non-zero-sum single-shot game where players play simultaneously. The game is restricted to a two-player (...

Accepted, January 20, 2005. NOT INFREQUENTLY, PATIENTS with bilateral cerebral aneurysms are encountered. In such patients, the ability to treat bilateral aneurysms through a unilateral approach spares the patient the risk and inconvenience associated with a separate craniotomy. The contralateral approach for aneurysm repair is technically feasible and safe in appropriately selected patients. H...

We consider a k-out-of-N reliability system with identical components having exponential lifetimes. There is a single repairman who attends to failed components on a firstcome first-served basis. The repair times are assumed to be of phase type. The system has K spares that can be used according to a probabilistic rule to extend the lifetime of the system. The system is analyzed using Markov ch...

The aim of this paper is to treat the analytical solution of the truncated interarrival hyperexponential machine interference queue: H2/M/1/m+Y/m+Y in case of two branches with the following concepts: balking, reneging, state-dependent, spares, and an additional server for longer queues. Our research treats the general case for the values of m and Y considering the discipline FIFO. And some spe...

In this paper a novel methodology to achieve fault tolerance in VLSI Array Processors is proposed. A “Fence” based approach is adopted in which the logic array is partitioned and spares are distributed along the boundary of the active array. The emulator as in conventional fault tolerance techniques takes care of fault mapping and reconfiguration. The latency, reconfiguration interconnect lengt...
