Neural networks in which 'commands' spread 'horizontally' across multiple neurons have been believed to mediate motor pattern variation. A recent study shows that dedicated 'vertical' neural pathways can also underlie these variations.

We describe a proof dedicated meta-language, called Ltac, in the context of the Coq proof assistant. This new layer of meta-language is quite appropriate to write small and local automations. Ltac is essentially a small functional core with recursors and powerful pattern-matching operators for Coq terms but also for proof contexts. As Ltac is not complete, we describe an interface between Ltac ...

There is increasing evidence that multimedia traffic in a variety of networks including the Internet, exhibits properties of self-similarity such as long-range dependence and a high-degree of correlation between arrivals. The demands of self-similar traffic impose unique new requirements in switch design, especially as far as the buffering strategy is concerned. In this paper, we study buffer s...

Since data rates for cell-edge users cannot be improved by merely increasing transmission power due to inter-cell interference (ICI), the interference management and alignment become crucial for cell-edge users. In this paper, we consider a simple approach where each base station (BS) in coordination transmits signals to a dedicated user through multiple subcarriers shared by adjacent BSs so th...

Many genes are regulated as an innate part of the eukaryotic cell cycle, and a complex transcriptional network helps enable the cyclic behavior of dividing cells. This transcriptional network has been studied in Saccharomyces cerevisiae (budding yeast) and elsewhere. To provide more perspective on these regulatory mechanisms, we have used microarrays to measure gene expression through the cell ...

In the mammalian brain, there is a large volume of white matter dedicated to long-range wiring, separated from the neuron cell bodies and short-range wiring. In the avian brain, no such dedicated volume exists. Assuming that evolution has maximised brain functionality, what are the advantages of the mammalian arrangement from an engineering point of view? To find possible answers to the questio...

We present a theory for automata in HOL, which is dedicated towards formal hardware synthesis. The theory contains deenitions for formally representing and transforming automata. In this approach hardware is represented by automata descriptions and formal synthesis is performed by applying formally proven theorems. The approach presented is constructive | i.e. starting from speciications at hig...

Viral marketing has attracted considerable concerns in recent years due to its novel idea of leveraging the social network to propagate the awareness of products. Specifically, viral awareness spread by propagating the information to their friends via their social relationships. Extensive studies have been conducted for maximizing the awareness spread given the number of seeds (the Influence Ma...

We have proposed the heuristic Load Balancing (LB) scheduling (Shr et al., 2006a) (Shr et al., 2006b) (Shr et al., 2006c) and Multiagent Scheduling System (MSS) (Shr, et al. 2006d) approaches to provide solutions to the issue of dedicated photolithography machine constraint. The dedicated photolithography machine constraint, which is caused by the natural bias of the photolithography machine, i...

Abstract Cell-aware test (CAT) explicitly targets faults caused by defects inside library cells to improve quality, compared with conventional automatic pattern generation (ATPG) approaches, which target only at the boundaries of cells. The CAT methodology consists two stages. Stage 1, based on dedicated analog simulation, characterization per cell identifies cell-level detects cell-internal de...
