A Metric for Secrecy-Energy Efficiency Tradeoff Evaluation in 3GPP Cellular Networks
Physical-layer security is now being considered for information protection in future wireless communications. However, a better understanding of the inherent secrecy of wireless systems under more realistic conditions, with a specific attention to the relative energy consumption costs, has to be pursued. This paper aims at proposing new analysis tools and investigating the relation between secrecy capacity and energy consumption in a 3rd Generation Partnership Project (3GPP) cellular network , by focusing on secure and energy efficient communications. New metrics that bind together the secure area in the Base Station (BS) sectors, the afforded date-rate and the power spent by the BS to obtain it, are proposed that permit evaluation of the tradeoff between these aspects. The results show that these metrics are useful in identifying the optimum transmit power level for the BS, so that the maximum secure area can be obtained while minimizing the energy consumption
Formation of the -N(NO)N(NO)- polymer at high pressure and stabilization at ambient conditions
A number of exotic structures have been formed through high-pressure chemistry, but applications have been hindered by difficulties in recovering the high-pressure phase to ambient conditions (i.e., one atmosphere and 300 K). Here we use dispersion-corrected density functional theory [PBE-ulg (Perdew-Burke-Ernzerhof flavor of DFT with the universal low gradient correction for long range London dispersion)] to predict that above 60 gigapascal (GPa) the most stable form of N(2)O (the laughing gas in its molecular form) is a one-dimensional polymer with an all-nitrogen backbone analogous to cis-polyacetylene in which alternate N are bonded (ionic covalent) to O. The analogous trans-polymer is only 0.03âŒ0.10 eV/molecular unit less stable. Upon relaxation to ambient conditions, both polymers relax below 14 GPa to the same stable nonplanar trans-polymer. The predicted phonon spectrum and dissociation kinetics validates the stability of this trans-poly-NNO at ambient conditions, which has potential applications as a type of conducting nonlinear optical polymer with all-nitrogen chains and as a high-energy oxidizer for rocket propulsion. This work illustrates in silico materials discovery particularly in the realm of extreme conditions (very high pressure or temperature)
New Indico module for Paper Review and Edit documentation and promotion
The group Collaboration, Devices and Applications (CDA) in CERN IT Department provides a big number of services which are very visible to the end-user, under-going continuous development, while ensuring top quality availability and support. One of these services is Indico that is undergoing a major OF the Conference Paper Review module and introduces a new module for Conference Paper Editing. Indico is an open-source tool used every day at CERN for event organization and collaboration. It can be used for lectures, meetings, workshops and conferences. It provides Reviewing functionalities for conference papers -one of the functionalities that has been redesigned -but it was also expanded to review slides and posters as conference material.. The Editing module is intended to enhance and extend the complex process of change management in a certain material. Paper Reviewing is concerned with the content and scientific correctness of the paper, whereas Editing intends to focus on the material layout, review comments or even editor suggestions
