The avian auditory brainstem displays parallel processing, a fundamental feature of vertebrate sensory systems. Nuclei specialized for temporal processing are largely separate from those processing other aspects of sound. One possible exception to this parallel organization is the inhibitory input provided by the superior olivary nucleus (SON) to nucleus angularis (NA), nucleus magnocellularis ...

The avian auditory brain stem consists of a network of specialized nuclei, including nucleus laminaris (NL) and superior olivary nucleus (SON). NL cells show sensitivity to interaural time difference (ITD), a critical cue that underlies spatial hearing. SON cells provide inhibitory feedback to the rest of the network. Empirical data suggest that feedback inhibition from SON could increase the I...

This study in Egypt, measured the son preference index, its determinants, and impact on reproductive behaviour and intention of 400 mothers attending for delivery. Overall son preference index was 1.4. The causes of sex preference were mainly psychological and social. Mothers with only girls were 496 times more likely to prefer a son as compared to those with boys only. Mothers with illiterate ...

The aim of this paper is to give a complete classification of irreducible finite-dimensional representations of the nonstandard q-deformation U ′ q(son) (which does not coincide with the Drinfel’d-Jimbo quantum algebra Uq(son)) of the universal enveloping algebra U(son(C)) of the Lie algebra son(C) when q is not a root of unity. These representations are exhausted by irreducible representations...

In Self-Organizing Networks (SONs), a potentially large number of SON functions are available that autonomously perfom network management tasks. Different functions are e.g. available for the optimization of the network, and they can have conflicting goals. To ensure an effective optimization of the overall network, coordination of SON functions is necessary. For this purpose, we developed a po...

The tensor product of vector and arbitrary representations of the nonstandard q-deformation U ′ q(son) of the universal enveloping algebra U(son) of Lie algebra son is defined. The Clebsch– Gordan coefficients of tensor product of vector and arbitrary classical or nonclassical type representations of q-algebra U ′ q(son) are found in an explicit form. The Wigner–Eckart theorem for vector operat...

Khaqani is one of the most important poets in Persian literature. His artistic personality is a complex character; he has worked on various branches of art and elegy is one of the main of these branches. Khaqani has composed over sixty elegies that are considered his masterpieces. His personal elegies are the most famous and the most artistically composed Persian elegies. Seven of these elegies...

Located in the ventrolateral region of the avian brainstem, the superior olivary nucleus (SON) receives inputs from nucleus angularis (NA) and nucleus laminaris (NL) and projects back to NA, NL, and nucleus magnocellularis (NM). The reciprocal connections between the SON and NL are of particular interest because they constitute a feedback circuit for coincidence detection. In the present study,...
