The improper Gaussian signaling (IGS) technique can improve the achievable rate of an interference-limited network by fully exploiting second-order statistics complex signaling. This paper addresses outage performance analysis a two-user downlink non-orthogonal multiple access (NOMA) system using IGS in presence imperfect successive interference cancellation (SIC). strong channel user (SU) adop...

The aim of this paper is to describe an original approach which consists of designing an Information Gathering System (IGS). This system gathers the most relevant information related to the patient. Our IGS is based on using questionnaire ontology and adaptive engine which collects relevant information by prompting the whole significant questions in connection with the patient’ s medical backgr...

The human bacterial pathogen Streptococcus pyogenes has developed a broad variety of virulence mechanisms to evade the actions of the host immune defense. One of the best-characterized factors is the streptococcal cysteine protease SpeB, an important multifunctional protease that contributes to group A streptococcal pathogenesis in vivo. Among many suggested activities, SpeB has been described ...

This paper presents a review of the state of the art of visualization in mixed reality image guided surgery (IGS). We used the DVV (data, visualization processing, view) taxonomy to classify a large unbiased selection of publications in the field. The goal of this work was not only to give an overview of current visualization methods and techniques in IGS but more importantly to analyze the cur...

Systems for genetically standardizing inbred strains of rodents have been well documented. With the internationalization of biomedical research, it has become necessary for multi-national laboratory animal suppliers to globally standardize more commonly used non-inbred toxicology models such as the Sprague Dawley and Hanover Wistar rat stocks. This paper describes one such breeding system, the ...

OBJECTIVE Image-guided surgical (IGS) technology has been clinically available for more than a decade. To date, no acceptable standard exists for reporting the accuracy of IGS systems, especially for lateral skull base applications. We present a validation method that uses the post from bone-anchored hearing aid (BAHA) patients as a target. We then compare the accuracy of 2 IGS systems-one usin...

A common feature of interspecific animal and plant hybrids is the uniparental silencing of ribosomal RNA gene transcription, or nucleolar dominance. A leading explanation for the genetic basis of nucleolar dominance in animal hybrids is the enhancer-imbalance model. The model proposes that limiting transcription factors are titrated by a greater number of enhancer-bearing subrepeat elements in ...

Aggregates of hyperphosphorylated tau protein are found in a group of diseases called tauopathies, which includes Alzheimer's disease. The causes and consequences of tau hyperphosphorylation are routinely investigated in laboratory animals. Mice are the models of choice as they are easily amenable to transgenic technology; consequently, their tau phosphorylation levels are frequently monitored ...

Polymorphism of the nuclear ribosomal DNA intergenic spacer (IGS) of the ectomycorrhizal basidiomycete Hebeloma cylindrosporum was studied to evaluate whether this sequence could be used in field studies to estimate the diversity of strains forming mycorrhizas on individual Pinus pinaster root systems. This sequence was amplified by PCR from 125 haploid homokaryotic strains collected in 14 P. p...
