In this letter we derive a deformed Dirac equation invariant under the κ–Poincaré quantum algebra. A peculiar feature is that the square of the κ–Dirac operator is related to the second Casimir (the κ–deformed squared Pauli–Lubanski vector). The “spinorial” realization of the κ–Poincaré is obtained by a contraction of the coproduct of the real form of SOq(3, 2) using the 4–dimensional represent...

Single mode optical fibers having minimum non-zero dispersion over the spectral windows of 1300 and 1550 nm region are essential for the multi-channel operation of dense wavelength multiplexed systems and minimizing the nonlinear four wave mixing effects This paper demonstrates that nonzero dispersion flattening of the dispersion factor extends over a wavelength range of more than 350 nm is ach...

Two innovative high-speed low power parallel 8-bit counter architectures are proposed. Then, High speed 8-bit frequency divider circuits using the proposed architectures are realized. The proposed parallel counter architectures consist of two sections – The Counting Path and the State Excitation Module. The counting path consists of three counting modules in which the first module (basic module...

We construct new leakage-resilient signature schemes. Our schemes remain unforgeable against an adversary leaking arbitrary (yet bounded) information on the entire state of the signer (sometimes known as fully leakage resilience). The main feature of our constructions, is that they offer a graceful degradation of security in situations where standard existential unforgeability is impossible. Th...

There are several significant advantages of memristors, such as their nano scale, fast switching speed, power efficiency and compatibility with CMOS technology, one the alternatives in next generation semiconductor storage devices. D-flip-flops (DFFs) based on traditional process have some shortcomings, including a large area, high power, charge leakage when scaling down. However, memristors of...

In this paper we propose a methodology to design high-speed, power-efficient static frequency dividers based on the low-voltage Folded MOS Current Mode Logic (FMCML) approach. A modeling strategy analyze dependence of propagation delay and power consumption bias currents divide-by-2 (DIV2) cell is introduced. We demonstrate that behavior FMCML DIV2 different both from one conventional MCML DFF ...

Relevance. Outward foreign direct investment (OFDI) and international trade are traditionally viewed as key drive of economic integration globalization. At the same time, relationship between these phenomena is ambiguous both from theoretical empirical points view. This study contributes to existing literature by analyzing outward for countries with different levels income per capita. Research ...

The high bandwidth and the relatively long-lived characteristics of digital video are key limiting factors in the wide-spread usage of streaming content over the Internet. The problem is further complicated by the fact that video popularity changes over time. In this paper, we study caching issues for a cluster-based streaming proxy in the face of changing video popularity. We show that the cac...
