Rethinking the role of interference in wireless networks

Abstract: This article re-examines the fundamental notion of interference in wireless networks by contrasting traditional approaches to new concepts that handle interference in a creative way. Specifically, we discuss the fundamental limits of the interference channel and present the interference alignment technique and its extension of signal alignment techniques. Contrary to this traditional view, which treats interference as a detrimental phenomenon, we introduce three concepts that handle interference as a useful resource. The first concept exploits interference at the modulation level and leads to simple multiuser downlink precoding that provides significant energy savings. The second concept uses radio frequency radiation for energy harvesting and handles interference as a source of green energy. The last concept refers to a secrecy environment and uses interference as an efficient means to jam potential eavesdroppers. These three techniques bring a new vision about interference in wireless networks and motivate a plethora of potential new applications and services.

Towards the glueball spectrum from unquenched lattice QCD

Abstract: We use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique includes glueball scattering states. The measurements were made using 2150 configurations at 0.092 fm with a pion mass of 360 MeV. We report masses for 10 glueball states. We discuss the prospects for unquenched lattice QCD calculations of the oddballs.

Student Teachers’ Beliefs about Creativity

Abstract: The purpose of the present study was to examine student teachers’ beliefs about creativity, creative outcomes, and factors related to creativity. Even though the importance of facilitating creativity in educational settings has been recognised, little attention has been paid to teachers’ beliefs about creativity. In this study, a questionnaire, designed to explore conceptualisations of creativity and issues related to it, was administered to 49 student teachers. The results indicated that student teachers tend to perceive creativity as a general ability primarily manifested in the context of artistic endeavours. Moreover, creative outcomes were thought to be novel but not necessarily appropriate or correct. These findings are discussed with respect to their educational implications.
