INTRODUCTION We tested the latent variable "δ" (for "dementia")'s ability to predict conversion to "mild cognitive impairment" (MCI) and Alzheimer's disease (AD). METHODS An ethnicity equivalent d homolog ("dEQ") was constructed in n = 1113 Mexican- American (MA) and n = 1958 non-Hispanic white (NHW) participants in the Texas Alzheimer's Research and Care Consortium. "Normal Controls" (NC) (n...

Boolean circuits are well established as a data structure for building propositional encodings of problems in preparation for satisfiability solving. The standard method for converting Boolean circuits to clause form (naming every vertex) has a number of shortcomings In this paper we give a projection of several well-known clause form conversions to a simplified Boolean circuit. We introduce a ...

Optical communication is attracting more and more attentions because of its huge bandwidth to meet the ever increasing demand of emerging computing/networking applications. In this paper we study distributed scheduling algorithms to resolve output contentions in WDM optical interconnects with wavelength conversion ability. We consider the general case of limited range wavelength conversion, inc...

In this paper, we investigate Residue Number System (RNS) to decimal conversion which is an important issue concerning the utilization of RNS numbers in Digital Signal Processing (DSP) applications. We propose a reverse converter using the moduli set {2n+1, 2n, 2n−1}. First, we show that this converter does not require the computation of multiplicative inverses. Next, we simplify the Chinese Re...

Most of the existing voice conversion methods calculate the optimal transformation function from a given set of paired acoustic vectors of the source and target speakers. The alignment of the phonetically equivalent source and target frames is problematic when the training corpus available is not parallel, although this is the most realistic situation. The alignment task is even more difficult ...

The here presented work reports on incorporation of a core grammar of Greek Sign Language (GSL) into a Greek to GSL conversion tool. The output of conversion feeds a signing avatar, enabling dynamic sign synthesis. Efficient conversion is of significant importance in order to support access to e-content by the Greek deaf community, given that the conversion tool may well be integrated into vari...

The model of South et al. [South et al. (1995) Enzyme Microb Technol 17(9): 797-803] for simultaneous saccharification of fermentation of cellulosic biomass is extended and modified to accommodate intermittent feeding of substrate and enzyme, cascade reactor configurations, and to be more computationally efficient. A dynamic enzyme adsorption model is found to be much more computationally effic...

This paper presents a novel three-phase utility frequency to high frequency soft switching power conversion circuit with dual mode pulse width modulation and pulse density modulation for high power induction heating applications as melting of steel and non ferrous metals, annealing of metals, surface hardening of steel and cast iron work pieces and hot water producers, steamers and super heated...
