Quantum-dot cellular automata (QCA) are a promising nanotechnology to implement digital circuits at the nanoscale. Devices based on QCA have the advantages of faster speed, lower power consumption, and greatly reduced sizes. In this paper, we are presented the circuits, which generate random numbers in QCA.  Random numbers have many uses in science, art, statistics, cryptography, gaming, gambli...

The Polymer Diagnostics Section (Code 6122) of the U.S. Naval Research Laboratory (NRL) has expertise in solid state nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and nuclear quadrupole resonance (NQR). In 1983, NRL established an interagency agreement with the Federal Aviation Administration (FAA) to advise the FAA on NMR methods to detect explosives. We were aware of ear...

This paper analyzes the ‘institutionality’ of Brazil’s National Health System, stressing crucial aspects to be dealt with, due to a return to the Public Health Reform Project. The reflection focus on the System ́s institutional configuration, covering issues related to the process for its political and management conduct, rooted in the authoritarian/patrimonialistic organizational culture of the...

We report a quantum random number generator based on the photon-number-path entangled state that is prepared by means of two-photon quantum interference at a beam splitter. The randomness in our scheme is truly quantum mechanical in origin since it results from the projection measurement of the entangled two-photon state. The generated bit sequences satisfy the standard randomness test.

In this paper, we discuss the self-consistency condition for the spherical symmetric Klein-Gordon equation. And then discuss a natural possibility that gravity and weak coupling constant gG and GW may be defined after gEM . In this point of view, gravity and the weak force is subsidiary derived from electricity. Unified solution for each particle field is calculated. ∗Electronic address:nisikaw...

in this study two indices of tempo and quantum of fertility for the city of tehran are calculated. the tables are based on data which have been collected in a survey in 1986. the sampling was administrated at two stages. at the beginning 158 geographical points were considered (the number of first birth order during 24 hours in tehran), then on the first stage 17 random geographical points were...

Julian Birkinshaw believes that corporate entrepreneurship can play an important strategic rôle in the business development of large, multinational firms, and he particularly identifies internal initiatives by subsidiary companies. The growth of network organizations is relevant here, and he puts forward a framework for an ‘internal market’ to understand how they work. The internal market model...

This study offers an empirical test and extension of Gupta & Govindarajan’s typology of subsidiary roles based on knowledge inflows and outflows. A four-fold typology of subsidiary roles – global innovators, integrated players, implementors and local innovators – is tested using a sample of 169 subsidiaries of MNCs headquartered in the US, Japan, UK, Germany, France and the Netherlands. Results...
