An investigation is being pursued to determine the best pH sensor for assessing tissue viability during the process of reconstructive surgery. Two different pH sensors are being evaluated in a preliminary study designed to improve upon the standard glass pH electrode: an ion-selective field effect transistor (ISFET) sensor and a conventional glass electrode. Preliminary test results show that the...
The characteristics of physical manual dexterity are defined and analyzed to provide the basis for a numerical rating system. Physical manual dexterity is based on the actual functionality and fitness of the hand and is assessed independently of higher neural ability. A method has been developed to test and analyze define characteristics. This method is expanded and integrated into a quantitative...
Clozaril, an antipsychotic agent, has several harmful side effects. An established computerized database was used to monitor Clozaril patients in New York State (NYS) Psychiatric Centers. Six centers with a total of 138 Clozaril patients were monitored from June to December 1991. White blood cell test results (WBC, % Gran (percentage of granulocytes), Hash Gran (absolute number of granulocytes)) were...
Changes in electroencephalogram (EEG) were analyzed at different levels of halothane anesthesia. Five experiments were carried out on mongrel dogs. Four channels of EEG data were recorded, at different anesthetic levels. A tenth-order autoregressive (AR) model was used to represent the EEG signal. The AR model parameters were used as input to a three-layer perceptron feedforward neural network, and...
