Flip-flops is critical timing elements in digital circuits which have a large impact on the circuit speed and power consumption. The performance of flip-flop is an important element to determine the efficiency of the whole synchronous circuit . In an attempt to reduce power consumption in flip-flops a low-power flip-flop (FF) design featuring an explicit type pulse-triggered structure and a mod...

Valproic acid (VPA) is a short, branched fatty acid with broad-spectrum anticonvulsant activity. It has been suggested that VPA acts directly on the plasma membrane. We calculated the free energy of interaction of VPA with a model lipid bilayer using simulated annealing and the continuum solvent model. Our calculations indicate that VPA is likely to partition into the bilayer both in its neutra...

AMPA receptors are hetero-oligomers composed of subsets of four distinct subunits, termed GluR1, GluR2, GluR3, and GluR4. Using quantitative reverse transcription-PCR analysis, we have found that light-induced degeneration of rat retina dramatically suppresses developmental progression of the flip-to-flop alternative splicing switch of retinal GluR1 mRNA. When animals were raised under standard...

The sequential element (flip-flop) is a basic building block to design any clocking system, which consists of the clock distribution tree and flip-flops. A large portion of the on chip power is consumed by the clocking system the total power consumption of the clocking system depends on both clocking distribution tree and also the register elements (flip-flops). The power consumption of registe...

A modified Linear Feedback Shift Register is designed in which power consumption reduction by deactivating the clock signal to Flip Flop when the output signal is same as input signal. The power consumption of the new LFSR is reduced due to the reduced switching of Flip Flop To verify, the maximum, minimum and average

This paper presents an architecture for an all optical switching node. The architecture is suitable for optical packet and optical burst switching and provides appropriate contention resolution schemes and QoS guarantees. A concept, called virtual memory, is developed to allow controllable and reasonable periods for delaying optical traffics. Related to its implementation, several engineering i...

The ‘flip-flop’ phenomenon has now been found to occur on several late-type stars: active longitudes, associated with dark regions of the surface, are seen to jump by 180◦. A simple non-linear non-axisymmetric mean field dynamo model is described, in which for the first time magnetic behaviour is found that is akin to the observed flip-flop.

Glutamatergic transmission converging on calcium signaling plays a key role in dendritic differentiation. In early development, AMPA receptor (AMPAR) transcripts are extensively spliced and edited to generate subunits that differ in their biophysical properties. Whether these subunits have specific roles in the context of structural differentiation is unclear. We have investigated the role of n...

In this paper, we introduce design models for Totally Self Checking, Code Disjoint (T S C / C D) and Strongly Fault Secure, Strongly Code Disjoint (SFS/SCDJ synchronous controllers. The T S C / C D and SF / S C D models based on two new proposed low-cost, modular, Totally Self Checking (TSC), edge triggered and error propagating (code disjoint) Flip-Flops; one, a D Flip-Flop which can be used i...

The photochromic fluorescence switching of a fulgimide derivative was used to implement the first molecule-based D (delay) flip-flop device, which works based on the principles of sequential logic. The device operates exclusively with photonic signals and can be conveniently switched in repeated cycles.
