In this paper, we study the advantages of improper Gaussian signaling (IGS) with existence hardware impairments (HWI) and imperfect successive interference cancellation (SIC) in downlink two-user power-domain non-orthogonal multiple access (PD-NOMA) systems. We first provide input-output relationships for MIMO system HWIs then derive rate expressions each user. The signals are assumed to be gen...

The International GPS Service (IGS) has provided GPS orbit products to the scientific community with increased precision and timeliness. Many users interested in geodetic positioning have adopted the IGS precise orbits to achieve centimeter level accuracy and ensure long-term reference frame stability. Currently, a differential positioning approach that requires the combination of observations ...

Elastic proteins in the muscles of a nematode (Caenorhabditis elegans), three insects (Drosophila melanogaster, Anopheles gambiae, Bombyx mori) and a crustacean (Procambus clarkii) were compared. The sequences of thick filament proteins, twitchin in the worm and projectin in the insects, have repeating modules with fibronectin-like (Fn) and immunoglobulin-like (Ig) domains conserved between spe...

Comparative analyses of complete chloroplast (cp) DNA sequences within a species may provide clues to understand the population dynamics and colonization histories of plant species. Equisetum arvense (Equisetaceae) is a widely distributed fern species in northeastern Asia, Europe, and North America. The complete cp DNA sequences from Asian and American E. arvense individuals were compared in th...

Fusarium proliferatum is a well-known plant pathogenic fungus-infected many crops. The present study was carried out to molecularly identified and characterized morphologically F. from various hosts substrates. species identity of the isolates verified as based on TEF-1α sequences phylogenetic analysis indicated high intraspecific variations. RFLP-IGS also variations which were clustered into t...

Neutralizing antibodies directed against hepatitis C virus (HCV) are present in Igs made from anti-HCV-positive plasma. However, these HCV-specific Igs are largely ineffective in vivo. The mechanism for the poor effectiveness is currently unknown. We hypothesize that the presence of nonneutralizing antibodies in HCV-specific Igs interferes with the function of neutralizing antibodies, resulting...

OBJECTIVE This study investigated whether glucose readings from a sensor sampling in interstitial fluid differ substantially from blood glucose (BG) values measured at the same time. RESEARCH DESIGN AND METHODS We have evaluated the relationship between BG and glucose extracted from interstitial fluid using the GlucoWatch (Cygnus, Redwood City, CA) biographer, a device that collects glucose f...
