In this work, we present the development of radial basis function circuits in CMOS technology. Two one-dimensional circuits, namely RBF1 and RBF2, are proposed for radial basis function realization, and their functionality is demonstrated by SPICE simulations and by their implementation with commercial MOSFET array integrated circuits. Multidimensional capability is demonstrated by the implemen...

OBJECTIVE To assess the cutoff values established by ROC curves to classify (18)F-NaF uptake as normal or malignant. MATERIALS AND METHODS PET/CT images were acquired 1 hour after administration of 185 MBq of (18)F-NaF. Volumes of interest (VOIs) were drawn on three regions of the skeleton as follows: proximal right humerus diaphysis (HD), proximal right femoral diaphysis (FD) and first verte...

Since Thiamine the first discovered vitamin among B complex vitamins is considered as an essential nutrient [1], and used for treatment of many disorders and diseases [2]; and because it is included as a component of different multi-vitamins, a variety of analytical methods have been proposed for its determination in pharmaceutical formulations. Those methods include flow injection analysis (FI...

ObjectiveTo compare transabdominal (TA) and transrectal (TR) ultrasonography of the prostate gland. DesignExperimental study. Animals10 intact male dogs that required euthanasia for reasons other than prostatic disease. ProceduresProstatic length (L), width (W) and height (H) were measured in T A (L1, W1 and H1) and TR (L2 and H2) ultrasonography. Prostatic volume was calculated using the formu...

spectrophotometric and electrochemical studies were successfully used in quantitative analysis of amitriptyline hydrochloride (ath) and nortriptyline hydrochloride (nth). conductometric titration were carried out in equeous solution using iodide and dopamine and serotonine as titrant. two new methods using spectrophotometry are dascribed for the determination of (ath) and (nth) with potassium b...

The growth of a thiamine pyrophosphate auxotroph of Escherichi coli was inhibited by either thiamine or thiamine monophosphate, and the growth of a thiamine monophosphate auxotroph was inhibited by thiamine. The thiamine pyrophosphate-dependent oxidation of pyruvate was inhibited by thiamine with whole cells of the thiamine pyrophosphate auxotroph but not with cell extracts prepared from the sa...
