Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...

Synthetic biology has potential spaceflight applications yet few if any studies have attempted to translate Earth-based synthetic tools into spaceflight. An exogenously inducible biological circuit for protein production in Arabidopsis thaliana , pX7-AtPDSi (Guo et al. 2003), was flown ISS and functionally investigated. Seedlings were grown a custom built 1.25 U plant greenhouse. Images recorde...

in this research, active capacitance circuit and the feature of negative resistance are analysed in details. also, a new active filter is presented based on active capacitance circuit. for simulations, we used matlab and advanced design system(ads). proposed active filter (rf) is a narrow band filter. the results of simulation shows some aspects of sustainability and low noise feature. the circ...

the purpose of this study was to examine serum selenium (se), lipoproteins and testosterone responses to a single session of circuit resistance exercise. fourteen male college students volunteered in the present study. blood samples were taken at 30minutes before, immediately after 25 and 60minutes of single session of circuit resistance exercise (10 exercise, 20s for each exercise, and at 60%1...

This paper deals with the most relevant issues about the integration of renewable generation in weak power grids. Initially, the main parameters that characterize these types of networks are reviewed, in terms of short circuit power, system inertia and frequency and voltage characteristics. Afterwards, improvement measures in the structure of weak power grids are proposed, analyzing different s...

DNA sequencing methods are the subject of continued interest in molecular biology for use in a wide variety of applications. Sequencing DNA by hybridization on a “DNA chip” has been estimated to increase the rate of DNA sequencing as much as one-million fold. In this process, the sequence of a target molecule is reconstructed by the complementary binding of a pool of random probe molecules. For...

The transformation of biochemical information into a physical or chemical signal is the basic idea behind a biosensor. The efficient detection of charged biomolecules by biosensor with appropriate device has caught tremendous research interest in the present decade. The present work is related to the simulation study of the performance of a functionalized surface of a biologically sensitive fie...

A class of reactive DNA circuits was adapted as erasable molecular imaging probes that allow fluorescent reporting complexes to be assembled and disassembled on a biological specimen. Circuit reactions are sequence-dependent and therefore facilitate multiplexed (multicolor) detection. Yet, the ability to disassemble reporting complexes also allows fluorophores to be removed and new circuit comp...

This paper reviews the experimental technique of whiplash PCR as intro duced in Hagiya et al in press and proposes a model of computation based on this technique in combination with assembly PCR Stemmer et al In this model based on GOTO graphs a number of NP complete problems can be solved in O biosteps including branching program satis ability the independent set problem and the Hamiltonian pa...
