OBJECTIVES To review the oral cancer (OC) studies that were conducted in Arab countries with regard to epidemiology, risk factors, and prognosis. METHODS A computer-based PubMed literature search was performed to retrieve studies conducted in the Arab world on epidemiology of OC. After screening for exclusion criteria, cross-referencing, and searching local journals, a total of 19 articles we...

Fresh leaves from khat trees (Catha edulis Celestrasae) are chewed daily by over 20 million people in Yemen and East African countries. Chewing khat (qat) is a popular social habit which has spread to Yemeni, Somali or East African communities in the USA and UK.

The use of artificial intelligence (AI) in sensor analytics is entering a new era based on the ubiquitous embedded connected devices. This transformation requires adoption design techniques that reconcile accurate results with sustainable system architectures. As such, improving efficiency AI hardware engines as well backward compatibility must be considered. In this paper, we present Hybrid-Fl...

Following a previous study of the one-loop factorization of the nonsinglet g2 structure function of the nucleon, we present in this paper the next-to-leading order coefficient functions in the singlet sector. To obtain the result, the partonic processes of virtual Compton scattering off two and three “on-shell” gluons are calculated. A key step in achieving the correct factorization is to separ...
