The gradient based algorithms are the most basic independent component analysis (ICA) algorithms, used in Blind signal separation (BSS). Because these algorithms adopt fixed step size, the choice of step size affects the performance and the convergence speed of the algorithm. In this paper, we propose a new algorithm SCG-ICA for blind signal separation. The new algorithm significantly improves ...

The present study aims at detecting molecular markers, based on RAPD, ISSR and AFLP, for the salttolerant wild barley Hordeum spontaneum as a little is known about its genetic structure and function. Barley is one of the most important cereal crops all over the world. Therefore, the identification of molecular markers for the salttolerant wild species is crucial for the future development of to...

Les auteurs rapportent 2 cas de fistules oesotrachéales isolées sans atrésie de l'oesophage, colligés au service de chirurgie pédiatrique au CHU Hassan II de Fès au Maroc entre 2008 et 2013. Il s'agit d'une anomalie rare représentée par un fin canal ascendant entre l'oesophage et la face postérieure de la trachée, à la hauteur du défilé cervico-thoracique. Elle se manifeste cliniquement par une...

In the present study Willbutrin (bupropion hydrochloride) was employed to induce mutagenic/ carcinogenic features in mice, i.e. undesirable cell division and DNA damage. The repair actions of fennel dry seeds and its extracted bioactive substance anethole supplied to Willbutrin-treatedmice in a dietary regime were investigated. Male Swiss albino mice (25-30gm) orally received Willbutrin dose (0...

The challenge of assimilation of the accumulating wealth of information necessitates the urge for having a comprehensive database. Such database can be used as an important tool in assisting scientists to decipher a host of biological phenomena ranging from the structure of biomolecules and their interaction to the whole metabolism of organisms and the evolution of species. This knowledge helps...
