Quadrature transceivers utilize complex signal processing in the analog front-end (AFE) to tackle the image problem in frequency up/downconversion. The image-rejection performance is limited by the unavoidable I/Q imbalance throughout the AFE. In this paper, an in-depth analysis and modeling of I/Q mismatch effects in 3 different AFE frequency up/downconverters in SIMULINK are presented to bett...

AIMS The aim of this study was to analyze factors related to rejection of care and behaviors directed towards others in nursing home residents with dementia. METHODS The relationship of lack of understanding, depression, psychosis and pain with rejection of care and behaviors directed towards others was explored using four assessments from the Minimum Data Set (MDS) within a period of 15 mont...

In this paper, we describe our effort in developing new method of false alarm rejection for keyword spotting type of speech recognition system. This false alarm rejection uses prosodic similarities, and works as posterior rescore basis. In keyword spotting, there is always false alarm problem. Here, we propose a technique to reject those false alarms using prosodic features. In Japanese, prosod...

Three methods of synthesizing correlations for meta-analytic structural equation modeling (SEM) under different degrees and mechanisms of missingness were compared for the estimation of correlation and SEM parameters and goodness-of-fit indices by using Monte Carlo simulation techniques. A revised generalized least squares (GLS) method for synthesizing correlations, weighted-covariance GLS (W-C...

We examined adjustment problems as risks for patterns of emotions, appraisals, and coping with rejection, and explored whether these processes could account for sex (boy/girl) differences in coping. Young adolescents (N = 669, grades 6-8) completed questionnaires, which assessed responses to peer rejection threat with two short scenarios. Using structural equation modeling to test a multivariat...

OBJECTIVE The present study uses structural equation modeling of latent traits to examine the extent to which family factors, cognitive factors and perceptions of rejection in mother-child relations differentially correlate with aggression at home and at school. METHODS Data were collected from 476 school-age (7-15 years old) children with a diagnosis of ADHD who had previously shown differen...

background acute rejection remains a major problem in renal transplantation and represents one of the most important causes of chronic allograft dysfunction and late graft loss. daclizumab is a genetically engineered human igg1 monoclonal antibody that binds specifically to the α chain of the interleukin-2 receptor, and may thus reduce the risk of rejection after renal transplantation. objectiv...
