We investigate the effective potential for a scalar Φ 4 theory with spontaneous symmetry breaking at finite temperature. All 'daisy' and 'super daisy' diagrams are summed up and the properties of the corresponding gap eqation are investigated. It is shown exactly that the phase transition is first order.

We present an experimental demonstration of the occurence of omnidirectional reflection in a finite multilayer of two elastic materials. This property is demonstrated in three different samples consisting of a few periods of Pb/Epoxy. The effect is fullfiled thanks to the large mismatch between the elastic parameters of the two materials in the multilayer. The thicknesses of the layers were cho...

12 tracted much attention due to unsur13 passed carrier mobility and high thermal 14 conductivity, 4 combined with excellent 15 chemical and thermal stability down to 16 the nanometer scale. The major drawback 17 is the absence of fundamental band gap, 18 which makes semimetallic graphene unsui19 table for conventional digital logic applica20 tions. Sustained efforts to engineer a band 21 gap i...

Nowadays, Information Society policies have been paying a lot of attention in bridging “Digital Divide” in our country. The gap between people from different socioeconomic backgrounds with regard to their opportunity and ability to access and make use of Information and Communication Technologies (ICT) is commonly regarded as a potential barrier for participation in the information society. ICT...

Organizations are increasingly adopting digital strategies and investing heavily in digital technologies and initiatives. However, to date, there does not appear to be a clear understanding of digital strategies and their purpose, which forms the motivation for this research. This research-in-progress study aims to address this research gap by exploring 1) the various conceptions of digital str...

In iterative schemes of identification and control one of the particular and important choices to make is the choice for a model uncertainty structure, capturing the uncertainty concerning the estimated plant model. This is typically done in some normbounded form, in order to guarantee robust stability and/or robust performance when redesigning the controller. Structures that are used in the re...

this study has investigated the effects of ict to increase efficiency and empowerment of rural women using data envelopment analysis (dea) to investigate the mechanism of effectiveness of information technology (ict) on the efficiency and empowerment of rural women in the village of gharn abad, golestan province. in this study, using survey methods, 38 users and 25 non-users of technology (cont...

Digitization is affecting almost all areas of business and society. It brings about opportunities for enterprises to design a digital business model. While a significant amount of research exist examining the conceptual foundation of business models in general, no comprehensive approach is available that helps enterprises in designing a digital business model. This paper addresses this gap and ...
