In this paper, a methodology for designing distributed model coplanar asymmetry transformer on gallium nitride (GaN) process is proposed, which can accurately characterize the transformer’s feature up to millimeter-wave band. The paper analyses transformer-based matching circuit and proposes practical design procedure. A two stage, based X-band power amplifier (PA) reported here. Using proposed...

In this work, by means of numerical simulations, we verify that four-wave mixing (FWM) processes, including depletion and parametric gain, generate a redistribution of pump power in distributed fiber Raman amplifiers (DFRAs). As a consequence of pump-pump FWM, FWM products are generated, as well as a power exchange between pumps, which produces degradation in the performance of the amplifier du...

Deriving a dynamic model based on the coupled-mode and carrier rate equations, the effects of coupling coefficient and corrugation position on all-optical flip-flops (AOFF) we have analyzed in this paper. Also the self phase modulation (SPM) in the distributed coupling coefficient distributed feedback semiconductor optical amplifier (DCCDFB-SOA) has been implemented. Then the effects of SPM on ...

The mesotelencephalic dopamine (DA) system is heterogeneous with respect to nuclei, terminal loci, DA receptor subtypes, electrophysiological characteristics and response patterns, and neuropharmacological response to a range of agents. The majority of mesocortical and mesolimbic DA neurons originate in the ventral tegmental area. Mesostriatal DA neurons originate in substantia nigra pars compa...

because of participation in many aspects of human life, and due to oxidation-sensitive characteristics of dopamine (da) and arachidonoyl dopamine (aa-da), the necessity of biocompatible carrier to keep them against oxidation is of importance. in this work, we explored the putative binding sites of da and aa-da to -lactoglobulin (blg) as potent carrier. docking results identified the binding si...

The study of paraconsistent logic as a branch of mathematics and logic has been pioneered by Newton da Costa. With the growing advent of distributed and often inconsistent databases over the last ten years, there has been growing interest in paraconsistency amongst researchers in databases and knowledge bases. In this paper, we provide a brief survey of work in paraconsistent databases and know...
