Frequency-bin qubits possess unique synergies with wavelength-multiplexed lightwave communications, suggesting valuable opportunities for quantum networking the existing fiber-optic infrastructure. Although coherent manipulation of frequency-bin states requires highly controllable multi-spectral-mode interference, frequency processor (QFP) provides a scalable path gate synthesis leveraging stan...

Abstract The Networks of Genetic Processors (NGPs) are non-conventional models computation based on genetic operations over strings, namely mutation and crossover as it was established in algorithms. Initially, they have been proposed acceptor machines which decision problem solvers. In that case, has shown universal computing equivalent to Turing machines. this work, we propose NGPs enumeratio...

Task graph scheduling is a multi-objective optimization and NP-hard problem. In this paper a new algorithm on homogeneous multiprocessors systems is proposed. Basically, scheduling algorithms are targeted to balance the two parameters of time and energy consumption. These two parameters are up to a certain limit in contrast with each other and improvement of one causes reduction in the othe...

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...

RXTE ASM count rates from the X-ray pulsar Her X-1 began falling consistently during the late months of 2003. The source is undergoing another state transition similar to the anomalous low state of 1999. This new event has triggered observations from both space-and ground-based observatories. In order to aid data interpretation and telescope scheduling, and to facilitate the phase-connection of...

The structure and electronic properties of 1-ML Au supported on TiO2~110! have been theoretically investigated using the full potential linearized augmented plane-wave method. Based on total-energy and atomicforce calculations, the preferential adsorption site for the Au adatom is predicted to be the atop site above the fivefold surface Ti atom, with a bond length of dAu-Ti52.66 Å and an adsorp...

Apples comprise an important part of everyday diet. This fruit contains micronutrients such as vitamins, calcium, zinc, and fluoride. Moreover, apples contain a high percentage of dietary fiber. Apple is also rich in phytochemicals which act as antioxidants. This fruit is considered to be beneficial for overall health. But are apples effective in preserving oral health? This brief review provid...

The approximation ratio of the longest processing time (LPT) scheduling algorithm has been investigated in various studies. While tight is known for cases when all processors are identical, unknown have different speeds. In this study, we provide a three, four, and five processors. We show that ratios these no larger than lower bound provided by Gonzalez, Ibarra, Sahni (SIAM J. Computing 1977)....
