background & aim: lumbar spinal stenosis (lss) is a common condition. this congenital or acquired stenosis has multiple etiologies. the goal of this study was to describe intraoperative pathoanatomic findings of lumbar spinal stenosis observed within a black african population. methods & materials/patients: it was a retrospective and descriptive study performed at departmental teaching hospital...
This write-up presents the design and analysis of several algorithms for determining the maximum sum of certain subsets of one-dimensional arrays. In the first section, we consider the Maximum Subsequence Sum (MSS) problem: given an array A with signed integer elements, find a contiguous subarray with the maximum possible sum. In Section 2, we extend our algorithm to handle the case of cyclic s...
The recent establishment of cloud computing and its increasing importance for consumers have attracted new ways of service creation and provisioning over the internet. Research has dealt with the establishment of new cloud computing markets and new opportunities for collaboration in these emerging markets. We found that the necessary decisions are very much similar to decisions that have to be ...
Expansion of cattail, Typha domingensis , is perhaps the most conspicuous indicator of long-term degradation of the Florida Everglades. The spread of cattail in the Everglades has been tracked at a landscape scale through photointerpretation of aerial and satellite photography (Rutchey and Vilchek 1994, Jensen et al. 1995, Rutchey and Vilchek 1999 and Rutchey et al. 2008) and has provided an im...
The muscarinic acetylcholine G-protein-coupled receptors are implicated in diseases ranging from cognitive dysfunctions to smooth-muscle disorders. To provide a structural basis for drug design, we used the MembStruk computational method to predict the 3D structure of the human M1 muscarinic receptor. We validated this structure by using the HierDock method to predict the binding sites for thre...
Cytogenetic analysis of short-term cultures was carried out on 109 lipomas from 92 patients. Clonal chromosomal abnormalities were pres ent in 50% of the tumors analyzed. Based on the results, three main Cytogenetic groups were identified and included: (a) tumors with normal karyotypes, (b) tumors with abnormalities involving region ql3-15 on chromosome 12, and (c) tumors with other clonal aber...
