Abstract This paper investigates physical layer security analysis of cooperative non-orthogonal multiple access (NOMA) communication system. A virtual full-duplex (VFD) relaying scheme with an untrusted amplify-and-forward (AF) half-duplex (HD) relay and a trusted decode-and-forward (DF) HD is used in this system to improve the spectral efficiency. In order prevent from eavesdropping, simple pr...

What is Europe PMC? Europe PMC [2] is a global, free, biomedical literature repository, providing access to worldwide life sciences articles, books, patents and clinical guidelines. The resource currently contains over 32 million abstracts and more than 4 million full-text articles (see Figure 1). A subset of the full-text information corpus is the open-access literature that can be downloaded ...

Images (i.e., figures or tables) are important experimental results that are typically reported in bioscience full-text articles. Biologists need to access the images to validate research facts and to formulate or to test novel research hypotheses. We designed, evaluated, and implemented a novel user-interface, BioEx, that allows biologists to access images that appear in a full-text article di...

introduction: an overlooked but important part of successful root canal treatment is a straight-line access (sla). the purpose of this in vitro study was to compare the efficacy of introfile and prerace rotary instruments with gates glidden (gg) drills in gaining sla by cone-beam computed tomography (cbct). methods and materials: a total of forty five extracted mandibular first molars were sele...

abstract accurate prediction of hourly minimum temperature is required for various crop models which simulate photosynthesis and transpiration. such data can be used for crop protection and reducing the crops injuries due to freezing as well. our objective of this study is employing trigonometric and pattern recognition (k-nn) approaches to evaluate their potential in prediction of hourly tempe...

second language acquisition (sla) always happens when the learners live and have contact with the native speakers of a second language. although this study investigates learning english by ten native children of farsi, the authors try to simulate the second language acquisition environment. the research deals with the initial state and further development in the child second language learning o...
