Gap junctions have diverse roles in a wide variety of tissues and have recently become a subject of intense investigation in neural circuits where synchrony and oscillations may play an important part. In circuits where gap junctions are present, the possibility arises of identifying intercommunicating cells via introduction of tracer into one cell and observing its spread into its coupled neig...

the rapid scaling in modern cmos technology has motivated the researchers to design new analog-to-digital converter (adc) architectures that can properly work in lower supply voltage. an exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. this paper is going to review the recent development in t...

The technology of the digital still camera has recently achieved remarkable progress. The number of pixels in the main stream of consumer-use cameras has reached the 3 million-range, with 5 million the maximum. And for professional-use, the number of pixels has reached the 16 million. Digital still cameras convert signal data generated from these pixel CCD's to luminosity signals and chromatici...

In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...

Title of dissertation: DELAY INDUCED INSTABILITIES IN COUPLED SEMICONDUCTOR LASERS AND MACKEY-GLASS ELECTRONIC CIRCUITS Min-Young Kim, Doctor of Philosophy, 2005 Dissertation directed by: Professor Rajarshi Roy Department of Physics We describe two experimental systems where a time-delayed feedback mechanism plays an important role in inducing instabilities. The first system consists of two cro...

Quantum dot cellular Automata technology is used in this paper which overcomes the design constraints of nanoscale CMOS circuits. This paper presents the analysis of 2:4 decoder circuit using four different methodologies. QCA based Decoder circuit is implemented using coupled majority voter minority gate, 45 0 rotated cells, multilayer wire crossings and five input Majority Voter gate. Comparat...

In this paper, the case of inverse lag synchronization phenomenon of two mutually coupled chaotic oscillators, was studied. This type of synchronization is observed for the first time in continuous dynamical systems. The system consists of two identical double scroll chaotic circuits coupled via a linear resistor. For a specific region of the coupling value, the system appears inverse lag synch...
