Non–Newtonian gravity and coherence properties of light. Abstract In this work the possibility of detecting a non–Newtonian contribution to the gravitational potential by means of its effects upon the first and second–order coherence properties of light is analyzed. It will be proved that, in principle, the effects of a fifth force upon the correlation functions of electromagnetic radiation cou...

As educational institutions throughout the world increasingly offer courses via the Internet, a global lifelong learning economy is emerging in which institutions must compete for students worldwide. This competition is especially noticeable in the offering of postgraduate courses aimed at satisfying the continuing professional development needs of practitioners in a wide range of disciplines. ...

Individual digit-tip forces and moments during torque production on a mechanically fixed circular object were studied. During the experiments, subjects positioned each digit on a 6-dimensional force/moment sensor attached to a circular handle and produced a maximum voluntary torque on the handle. The torque direction and the orientation of the torque axis were varied. From this study, it is con...

Mobile data traffic is constantly rising at huge growth rates. One evolving method to counter this expansion is operation frequency, and so bandwidth, increase, as formal standardization activities on 60 gigahertz industrial, scientific and medical radio band began in 2005. In line with this, this paper proposes the utilization of low terahertz (THz) band for the next-generation of mobile and w...

To obtain a high data rate that is commensurate with the growing demand for internet services, fifth generation (5G) cellular networks will use bandwidth beyond 6 GHz, called millimeters waves (mm-waves), to higher. The first phase (phase I) of 5G network design user density, where optimized microcells are deployed at carrier frequency 700 MHz 20 bandwidth. second II) consists deployment which ...

—Cognitive radio is regarded as a key technique in the fifth generation communication system. We consider that the popular contents can be cached in cognitive mobile users who compose a cognitive Device-to-Device (D2D) network. Cached

The millimeter-wave band is a much discussed candidate as additional access technology of the fifth generation of mobile radio networks (5G). This paper gives a background on the fundamentals of mmwave propagation and then investigates a set of reference scenarios, where the new bands will enable new applications and use cases.

Recent studies have described muscle synergies as overlapping, multimuscle groups defined by synchronous covariation in activation intensity. A different approach regards a synergy as a fixed temporal sequence of bursts of activity across groups of motoneurons. To pursue this latter definition, the present study used a principal component (PC) analysis tailored to reveal the across-muscle tempo...
