Most combinatorial optimization problems cannot be solved exactly. A class of methods, called metaheuristics, has proved its eeciency to give good approximated solutions in a reasonable time. Cooperative metaheuristics are a subset of metaheuristics, which implies a parallel exploration of the search space by several entities with information exchange(More)
Biomarker detection is one of the greatest challenges in Clinical Proteomics. Today, great hopes are placed into tandem mass spectrometry (MS/MS) to discover potential biomarkers. MS/MS is a technique that allows large scale data analysis, including the identification, characterization, and quantification of molecules. Especially the identification process,(More)
National expenditures on HIV/AIDS were estimated as summary indicators to assess the country's response to HIV/AIDS. The methodology is based on a matrix system describing the level and flow of health expenditures on HIV/AIDS: an adaptation of the National Health Accounts methods. The expenditures were classified by source (public, private, international),(More)
In this study, gamma irradiation induced degradation of orange peels (OP) was investigated. The lignocellulosic biomass degradation was carried out at doses of 0 (control), 600, 1800 and 3500 kGy using a Co-60 gamma radiation source. The samples were tested for total and reducing sugars. The concentrations of total sugars ranged from 0.530 g • g −1 in(More)
The identification and characterization of peptides from tandem mass spectrometry (MS/MS) data represents a critical aspect of proteomics. Today, tandem MS analysis is often performed by only using a single identification program achieving identification rates between 10-50% (Elias and Gygi, 2007). Beside the development of new analysis tools, recent(More)
The graphics processing unit (GPU) learning initiative is developed within a project awarded by the Moroccan Fulbright Alumni Association (MFAA), entitled "GPU Acceleration of Human Genome Sequencing". This project involves undergraduate students at Abdelmalek Essaadi University, and is conducted in collaboration with the High Performance Computing Lab(More)
