A new pipelined architecture for adaptive progressive thresholding (APT) is proposed. Unlike the conventional architectures that rely heavily on multipliers and dividers to evaluate the maximum between-class variance, our method employs a reconfigurable logarithmic computing unit to simplify the circuitry and increases the application’s agility to operational variation. Our logarithmic conversi...

this brief introduces a method of improving the power conversion efficiency of a dc-dc boost converter with passive snubber circuit. This method uses a passive snubber circuit which consists of two inductors, a capacitor, and a diode, to reduce switching loss. The use of passive soft switching methods has been emphasized as better alternative to active methods mainly because they do not require...

HNO has broad biological effects and pharmacological activities. Direct HNO probes for in vivo applications were recently reported, which are CuII-based complexes having fluorescence reporters with reaction to HNO resulting in CuI systems and the release of NO. Their coordination environments are similar to that in Cu,Zn-superoxide dismutase (SOD), which plays a significant role in cellular HNO...

Gene conversion is a recombinatorial mechanism which transfers genetic information from a donor into a recipient gene. A case of gene conversion between immunoglobulin VH region genes was analysed and palindromic sequences were found to be located near to the left recombinatorial breakpoint, which also is flanked by a direct repeat sequence. We performed a computer search for palindromes and di...

BACKGROUND Writing is a sequential motor action based on sensorimotor integration in visuospatial and linguistic functional domains. To test the hypothesis of lateralized circuitry concerning spatial and language components involved in such action, we employed an fMRI paradigm including writing and drawing with each hand. In this way, writing-related contributions of dorsal and ventral premotor...

Introduction Digital Signal Processing (DSP) affords greater flexibility, higher performance (in terms of attenuation and selectivity), better time and environment stability and lower equipment production costs than traditional analog techniques. Additionally, more and more microprocessor circuitry is being displaced with costeffective DSP techniques and products; an example of this is the emer...

Mathematical models and circuitry necessary for optimal energy conversion have been developed for piezoelectric devices because of their ability to convert mechanical energy to electrical energy. The piezoelectric device that is the focus of this study is a curved, thin unimorph prestressed bender. This device consists of layers of piezoelectric material, polyimide, and metal bonded at high tem...
