W.Fouad, A.Badr, and I.Farag, "AIFSA: A New Approach for Feature Selection and Weighting", International Conference on Informatics Engineering & Information Science , vol. 252, pp. 596-609, 2011. Abstract

Feature selection is a typical search problem where each state in the search space represents a subset of features candidate for selection. Out of n features, 2n subsets can be constructed, hence, an exhaustive search of all subsets becomes infeasible when n is relatively large. Therefore, Feature selection is done by employing a heuristic search algorithm that tries to reach the optimal feature subset. Here, we propose a new wrapper feature selection and weighting algorithm called Artificial Immune Feature Selection Algorithm (AIFSA); the algorithm is based on the metaphors of the Clonal Selection Algorithm (CSA). AIFSA, by itself, is not a classification algorithm, rather it utilizes well-known classifiers to evaluate and promote candidate feature subset. Experiments were performed on textual datasets like WebKB and Syskill&Webert web page ratings. Experimental results showed AIFSA competitive performance over traditional well-known filter feature selection approaches as well as some wrapper approaches existing in literature.

Purpose

To evaluate the efficacy of platelet rich fibrin as a membrane for coverage of immediate implants in the maxillary anterior region.

Patients and methods

Twelve implants were inserted into eight adult patients indicated for extraction & immediate implant insertion in one or more of the upper anterior teeth. A venous blood sample of 10 cc was obtained for each single implant. After implant placement, the peri-implant defect was filled with a mixture of autogenous bone (collected from the chin) and fibrin. A platelet rich fibrin membrane was used to cover the implant site. Clinical & radiographic evaluation was performed immediately, 3 and 6 months postoperatively to evaluate soft tissue healing & crestal bone stability.

Results

After 6 months, the marginal bone was stable in 83% of cases. Clinically, good soft tissue coverage was obtained. Radiographically, bone height showed a statistically significant decrease in the distal side while there was no statistically significant decrease at the mesial side. The change in defect depth was limited to 2 mm.

Conclusion

Platelet rich fibrin provided good soft tissue coverage over the immediate implants and it enhanced bone stability. The technique was easy to perform with good esthetic results.

This study pointed to explore clinical, biochemical, bacteriological and ultrasonographic changes in camels with chronic cystitis (n=15) and control animals (n=15). Blood and urine samples from these camels were submitted to laboratory investigations. The camels with chronic cystitis showed pollakiuria, dysuria, stranguria, haematuria, and inappropriate urination. The urine analysis revealed haematuria and pyuria. The isolated bacteria were E. coli (n=15), Corynebacterium renale (n=13) and mixed bacterial culture (n=2). The laboratory analysis of blood samples revealed leukocytosis and neutrophilia in diseased camels when compared with healthy ones. There was significant increase in the levels of globulin and fibrinogen with significant decrease in the albumin levels in diseased camels when compared to healthy ones. There was non-significant changes in triglyceride, cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT) activities, blood urea nitrogen (BUN) and creatinine levels in diseased camels when compared with healthy ones. The trans-rectal ultrasonographic examination in camels with chronic cystitis showed a narrow bladder lumen with severely thickened and corrugated bladder wall. Treatment trials failed in all cases under investigation.

Fine-structure energy levels, oscillator strengths and transitions probabilities for transitions among the fine-structure levels of the terms belonging to the 1s22s22p63s2np (2P), 1s22s22p63s2nd (2D) (n= 3-5) and 1s22s22p63s2ns (2S), 1s22s22p63s2nf (2F) (n= 4, 5) configurations of the Al-like ions Ar VI, K VII, and Ca VIII have been calculated. The calculations are based upon the general configuration interaction code CIV3 of Hibbert. Calculated values are compared with experimental and other theoretical results where some unpublished energy values and oscillator strengths are reported.
