Epidemiology of animal bites in Rafsanjan, southeast of Islamic Republic of Iran, 2003-05.

The incidence of animal bites in the Islamic Republic of Iran has been increasing in recent years. In a descriptive study of 1542 patients referred to a health centre in Rafsanjan city from 2003 to 2005, the incidence of animal bites in the area was estimated as 180, 195 and 241 per 100 000 in 2003, 2004 and 2005 respectively. Of the patients, 74% were bitten by dogs, 23% by cats and 3% by other animals (monkeys, rats, foxes, bats, donkeys, etc.). The mean time delay from injury to initial management was 15.1 (SD 29.8) hours. Rabies vaccine was given to 85% of cases, rabies vaccine plus rabies immunoglobulin to 15% and tetanus toxoid vaccine to 66%.

Supervised mutual-information based feature selection for motor unit action potential classification.

A new supervised mutual information-based feature selection method is presented. Using real motor unit action potential (MUAP) data from 10 EMG signals, the performances of 32 time-sample feature sets, feature subsets selected using first- and second-order mutual information and features obtained using linear discriminant analysis (LDA) and principal component analysis (PCA) were evaluated using a minimum Euclidean distance (MED) classifier. The evaluation showed that by using only 20 first-order features or only 15 second-order features mean error rates and error rate variations equivalent to using all 32 samples or LDA or PCA could be obtained. The computational cost of first-order feature selection was considerably less than LDA, PCA and second-order feature selection. The performance of first-order features was further evaluated using a more robust classifier. Unlike the MED classifier, the robust classifier only assigned a candidate MUAP if the assignment was sufficiently certain. For the robust classifier the average error rates using 20 features were similar to using the full feature set, yet higher assignment rates were obtained. Results from both evaluations suggest that the sets of first-order features were an efficient representation of lower dimension, which provided high accuracy classification with reduced computational requirements.
