G(u,u',u") = 0, (1) where u = u(x, x,..., x), and u', u" denote all the first and second partial derivatives of u. For simplicity we will assume here that both u and G are scalars and denote by ua, uab, the partial derivatives dau and respectively dahu; a,b =1,2, ..., n+1. Let u (x) be a given solution of (1). Our equation is said to be elliptic or hyperbolic at u°(x) according to whether the (...

background previous studies have proven the development of white matter hyperintensities (wmh) in methamphetamine and opioid users. opiates and methamphetamines (ma) are the most common addictive agents in iran. the adverse effects of drugs on the cns is of concern to specialists and researchers, and given that the neurotoxicity associated with methamphetamine is greater than opioids, it is hyp...

We consider the problem of designing optimal linear codes (in terms of having the largest minimum distance) subject to a support constraint on the generator matrix. We show that the largest minimum distance can be achieved by a subcode of a Reed-Solomon code of small field size. As a by-product of this result, we settle the GM-MDS conjecture of Dau et. al. in the affirmative.

conclusions: family-centered empowerment model, easily adapted to methamphetamine users and their families, leads to improved social supports and qol. results: mean scores of qol and social support dimensions changed significantly in two intervention groups (p < 0.0001), but didn’t change in the control group (p > 0.05). also, there was a positive significant relation (p < 0.05) between total s...

In this research various objective quality measures are evaluated in order to predict the intelligibility for a wide range of non-linearly processed speech signals and speech degraded by additive noise. The obtained results are compared with the prediction results of a more advanced perceptual-based model proposed by Dau et al. and an objective intelligibility measure, namely the coherence spee...
