The importance of multimedia databases has been growing over the last years in the most diverse areas of application, such as: Medicine, Geography, etc. With the growth of importance and of use, including the explosive increase of multimedia data on the Internet, comes the larger dimensions of these databases. This evolution creates the need for more efficient indexing structures in a way that ...

In my opening remarks the acoustics and signal processing involved in active control will be reviewed: both for enhancing audio signals and for attenuating acoustic noise. The physical limits due to the geometry of practical arrays will be discussed, together with the signal processing design methods that can be used to implement robust practical arrays, whose performance approaches these geome...

BACKGROUND Maternal smoking during pregnancy (MSDP) is an independent risk factor for offspring nicotine dependence (ND), but mechanisms remain unknown. We investigated prenatal glucocorticoid (cortisol) and androgen (testosterone) associations with offspring ND over 40 years and the possibility that prenatal glucocorticoids and androgens would mediate links between MSDP and offspring ND. MET...

The pathogenicity of Newcastle disease (ND) virus, isolated from ND outbreak in vaccinated chickens, was evaluated through experiments. The pathogenicity indexes (mean death time (MDT); 58 hr, intracerebral pathogenicity index (ICPI); 1.7 and intravenous pathogenicity index (IVPI); 2.51) indicated that the ND virus was velogenic. The ND virus caused lymphocytic necrosis in the spleen with fibri...

This paper defines the contextual natural deduction calculus ND for the implicational fragment of intuitionistic logic. ND extends the usual natural deduction calculus (here called ND) by allowing the implication introduction and elimination rules to operate on formulas that occur inside contexts. In analogy to the Curry-Howard isomorphism between ND and the simply-typed λ-calculus, an extensio...

Young growing animals appear to have significantly reduced "nutritional to short periods of unstressed starvation compared with adults, with resultant growth arrest and/or atrophy of diaphragm (Dia) muscle fibers. The aim of this study was to assess in an adolescent rat model of acute nutritional deprivation (ND; 72 h) the impact of insulin-like growth factor I (IGF-I), with or without added gr...

In this paper, a constructive general matrix factorization scheme is developed for extracting a nontrivial factor from a given nD (n > 2) polynomial matrix whose maximal order minors satisfy certain conditions. It is shown that three classes of nD polynomial matrices admit this kind of general matrix factorization. It turns out that minor prime factorization and determinantal factorization are ...

The adrenergic system has an important role in normal central nervous system function as well as in brain disease. The locus coeruleus, the main source of norepinephrine in brain, is involved in the regulation of learning and memory, reinforcement of sleep-wake cycle and synaptic plasticity. In Alzheimer’s disease, locus coeruleus degeneration is observed early in the course of the disease, yea...

Recent studies postulated the association between bullous pemphigoid (BP) and neurodegenerative disorders (ND). The autoantibodies to BP180 and/or BP230 may be present not only in BP, but also in ND as neuronal isoforms of these proteins are identified in the central nervous system. However, there are only scant data about the precise pathogenetic mechanisms interlinking ND and BP as well as th...
