Based on the density of connections between the nodes of high degree, we introduce two bounds of the spectral radius. We use these bounds to split a network into two sets, one of these sets contains the high degree nodes, we refer to this set as the spectral– core. The degree of the nodes of the subnetwork formed by the spectral–core gives an approximation to the top entries of the leading eige...

An anthropometric study and dietary investigations were conducted in an Iban community in the Sixth Division of Sarawak. 140 children aged 0 to 6 years, were assessed anthropometrically. Their mean weights and heights were much lower than those of their counterparts in Singapore. 7% of the children were nutritional dwarfs while about 68% were either wasted or wasted as well as stunted. Rice was...

in al-ta‘liqat–which is most likely a collection of avicenna’s lectures– it is intended to answer to a paradox concerning the knowledge of the substance. this paradox can be reconstructed this way: if, by knowing something, its quiddity comes to mind, then with knowing a substance its quiddity–which is a substance–comes to mind. conversely, according to peripatetic philosophy, knowledge is a qu...

A digital audio effect for real time mixing applications, which dynamically adapts to the multi-channel input, has been implemented. The resulting audio mix is the direct result of the analysis of the content of each individual channel with respect to the other channels. The implementation permits the enhancement of a source with respect to the rest of the mixture by selectivity unmasking its s...

We have measured by cation exchange high pressure liquid chromatography adult hemoglobin (HbA) concentration at birth in 6,123 unselected single newborn individuals. Probably because of the high precision of the analytical method used, we could demonstrate clear a relationship between HbA concentration and, respectively, gestational age and birth weight. We also demonstrated a significant diffe...
