The electron transport through a quantum sphere with three one-dimensional wires attached to it is investigated. An explicit form for the transmission coefficient as a function of the electron energy is found from the first principles. The asymmetric Fano resonances are detected in transmission of the system. The collapse of the resonances is shown to appear under certain conditions. A two-term...

-This paper explains a new approach to design Exclusive-OR gate using 2 transistors. A full adder circuit has been designed by using proposed 2T Exclusive-OR circuit and a transmission gate is used extensively in very large-scale integration (VLSI) application. The power dissipation of the adder is in range of 421.7256uw to 581.542uw in 0.35 um technology with a voltage supply is in the range o...

We have fabricated graphene devices with a top gate separated from the graphene layer by an air gap-a design which does not decrease the mobility of charge carriers under the gate. This gate is used to realize p-n-p structures where the conducting properties of chiral carriers are studied. The band profile of the structures is calculated taking into account the specifics of the graphene density...

The Gate diffusion input (GDI) is a novel technique for low power digital circuit design. This technique reduces the power dissipation, propagation delay, area of digital circuits and it maintains low complexity of logic design. In this paper, the 4×1 Multiplexer, 8×3 Encoder, BCD Counter and Mealy State Machine were implemented by using Pass Transistors (PT), Transmission Gate (TG) and Gate Di...

‘gate control’ theory. Stimuli are processed peripherally and their transmission determined by a gate set both in the spinal cord and the subcortical regions. Higher centres then determine motor, and other motivational, responses as well as interpreting psychological aspects. The gate is set according to competing spatially similar and adjacent stimuli as well as the brain’s arousal and attenti...

Ca(2+)-activated BK channels modulate neuronal activities, including spike frequency adaptation and synaptic transmission. Previous studies found that Ca(2+)-binding sites and the activation gate are spatially separated in the channel protein, but the mechanism by which Ca(2+) binding opens the gate over this distance remains unknown. By studying an Asp-to-Gly mutation (D434G) associated with h...

Photon storage with 250 ps rise time of the readout optical signal was implemented with indirect excitons in coupled quantum well !CQW" nanostructures. The storage and release of photons was controlled by the gate voltage pulse. The transient processes in the CQW were studied by measuring the kinetics of the exciton emission spectra after application of the gate voltage pulse. Strong oscillatio...

Major issues of NBI power supplies are a high-speed switching, regulation and transmission of dc ultra high voltage, and suppression of surge energy input to the beam source at breakdown. A GTO(gate turn off thyristor) inverter type power supply where the control is performed at low voltage ac side was designed for the ITER NB. Based on the remarkable progress of a high power IEGT (injection en...

New military communications require increased versatility for the transmission of a wide range of data, voice and images. There are many algorithms needed for communication like FFT (Fast Fourier Transform), DCT (Discrete Cosine Transforms), Viterbi coders and decoders, trellis techniques etc. Advances in VLSI technology continue to improve the quality of algorithm that can be implemented on a ...
