Using Video Simulation to Enhance RN-PCA Communication
… Nurses (RNs) and Patient Care Assistants (PCAs). From a general microsystem assessment initially performed on an urban hospital medical-surgical unit, 75% of respondents noted that the most pertinent issue to address was improving communication between RNs and PCAs. Literature review of …

Algorithms and Theory for Robust PCA and Phase Retrieval
… of \emph{robust principal component analysis} (PCA), which aims to recover an unknown low-rank matrix from a corrupted and partially-observed matrix. </p> <p>The robust PCA problem, originally nonconvex itself, has been solved via a convex relaxation based approach \emph{principal component …

Face Recognition: Study and Comparison of PCA and EBGM Algorithms
… discussed briefly. Principal Component Analysis (PCA) is the most efficient and reliable method known for at least past eight years. Elastic bunch graph matching (EBGM) technique is one of the promising techniques that we studied in this thesis work. We also found better results with EBGM method …

Posterior cerebral artery (PCA) infarcts and dreaming : a neuropsychological study
Recent case reports have shown that global loss of dreaming can result from medial occipitotemporal lesions. These findings have cast doubt on Solms's reformulation of Charcot-Wilbrand Syndrome (CWS) into two distinct disorders of dreaming, and caused substantial confusion in dream research as far …

The application of PCA as a movement pattern recognition technique: A proof of principle
… Applying principal components analysis (PCA) to whole-body motion data may provide an objective data-driven method to identify unique and statistically important movement patterns. Therefore, the primary purpose of this study was to determine if athletes’ movement patterns can be …

A liderança intermédia e a sua influência numa turma de Percursos Curriculares Alternativos (PCA)
… turmas de Percursos Curriculares Alternativos (PCA) são uma realidade escolar justificada e legislada, como uma das ofertas formativas do ensino básico para alunos que apresentem um quadro disruptivo de desencontros entre interesses pessoais e escolares. Num cenário “dantesco” da mudança social …

USING PRINCIPAL COMPONENT ANALYSIS (PCA) TO OBTAIN AUXILIARY VARIABLES FOR MISSING DATA IN LARGE DATA SETS
The purpose of this dissertation is to address an important issue in the imputation of missing data in large data sets. The issue can arise in any analysis in which auxiliary variables are used to inform a modern missing data handling procedure (e.g., FIML, MI) to support the missing at random …

Capitalization Methods of Production Credit Associations and Their Impact on Borrowers' Costs (Credit, Pca, Interest Rates)
Production Credit Associations (PCAs) are farmer-owned cooperatives which are intended to enhance the economic well-being of farmers and ranchers in the United States. A way that PCAs accomplish this purpose is by providing their borrowers low, stable cost credit services. The extent to which PCAs …

Monitoring Bacteria Cultures Using Near Infrared (nir) Binary Spectronephelometry (bsn), Raman Spectra and Principal Component Analysis (pca)
… characteristics of Principal Component Analysis (PCA) of Raman spectra, and their variation in bacterial cultures, as well as assessing the role of bacterial transport e.g., diffusion in performing and analyzing BSN, are presented.</p>

X-ray power density spectra of black hole binaries : a new deadtime model for the RXTE PCA
… we focus on the Proportional Counter Array (PCA) instrument of the Rossi X-ray Timing Explorer (RXTE), an orbiting observatory that offers fast, microsecond-level time resolution and modest spectral resolution for celestial X-ray sources. We derive a new model for the effect of detector …

The Interaction of Intensity and Deviance on Auditory Event-Related Potentials: Findings Using Principal Component Analysis (PCA) of Current Source Densities (CSDs)
… from stimulus-specific N1/P2 processes. A CSD-PCA approach was used to identify and quantify reference-independent patterns of activity underlying the ERP. Results show that the intensity dependence of N1/P2 is largely dependent on the context in which a given intensity was cast. Namely, a high …

The Comparison of Ondansetron or Dolasetron on the Prevention of Postoperative Nausea and Vomiting in Patients with intravenous Patient-Controlled Analgesia
… with intravenous patient-controlled analgesia(IV PCA). In this study, we evaluated the effect of ondansetron or dolasetron on the prevention of PONV in patients undergoing mastectomy with IV PCA. MATERIALS AND METHODS: 164 patients undergoing mastectomy were randomly divided into control …

Knee Angles and Axes Crosstalk Correction in Gait, Cycling, and Elliptical Training Exercises
… rotation (IE)). Principal Component Analysis (PCA) has recently been proposed as a post hoc method to reduce crosstalk errors and operates by minimizing the correlation between the knee angles [1, 2]. However, recent studies that have used PCA have neither considered exercises, such as cycling …

The Role of Il-8-Mediated Src Family Kinase Activation In Tumor-Tumor and Tumor-Stromal Interactions In Metastasis of Prostate Cancer
<p>Men with localized prostate cancer (PCa) have a 100% five-year survival rate, but this rate drops to 33% for men with metastatic disease. A better understanding of the metastatic process is needed to develop better therapies for PCa. Aberrant activation of protein tyrosine kinases, including Src …
