Chromosome aberrations (CA) and sister-chromatid exchanges (SCE) were measured in lymphocytes of (A) 32 healthy individuals working in the flower industry and exposed to pesticides, (B) 32 individuals exposed as above and hospitalized for bladder cancer, and (C) 31 controls. Compounds to which floriculturists were exposed included 18 nitro-organic(More)
Aflatoxin-albumin adducts in peripheral blood provide a measure of exposure to aflatoxin over the previous 2-3 months. In the present study, the levels of these adducts were determined in a group of individuals from The Gambia, West Africa and were compared in a cross-sectional study to the levels of various cytogenetic alterations (chromosomal aberrations,(More)
— In this article, we present some results on the application of fuzzy methods to the segmentation of multivariate medical images. We report the results obtained by using the Fuzzy C-mean (FCM) algorithm by J. Bezdek and the method by K. Rose, E. Gurewitz and G. Fox (RGF) based on the Maximum Entropy Principle (MEP) that avoids any a priori assumption on(More)
The use of centralized signal processing for dense urban mobile networks is gaining interest both in research and in industry. Gathering most of the base station functionalities in a processing pool would enable capacity sharing and the implementation of advanced techniques such as coordinated multi-point. Nevertheless, this puts stringent requirements on(More)
Earlier studies have produced evidence for an association between work-related styrene exposure and cytogenetic damage, while more recent studies have failed to show such an association. In the present study, chromosome aberrations (CA) and sister chromatid exchanges (SCE) were measured in peripheral blood lymphocytes of 46 male workers employed in a(More)
New technologies and architectures arise in the telecommunications industry in order to cater to the ever growing demands in terms of resource utilization, manageability and user experience. C-RAN and SDN represent two such novel paradigms, both advocating for centralization of a set of resources or control capabilities respectively. The C-RAN architecture(More)
Inter-cell interference (ICI) is considered as the most critical bottleneck to ubiquitous 4<sup>th</sup> generation cellular access in the mobile long term evolution (LTE). To address the problem, several solutions are under evaluation as part of LTE-Advanced (LTE-A), the most promising one being coordinated multipoint joint transmission (CoMP JT). Field(More)
