Background While SSFP CMR is the gold standard for assessing left ventricular (LV) function, it requires a regular cardiac rhythm and frequent breath-holds and not all patients with cardiovascular disease are able to achieve this. It is known that Compressed Sensing (CS) greatly reduces data acquisition time however its accuracy for LV volume and mass is currently unknown. This study compares v...

This study applies two approaches in creating a single scale from two separate statewide exams (Golden State Math Exam and California Standard Math Test) and compares some aspects of the two statewide tests. The first analysis involves a sequence of unidimensional Rasch scalings, using anchored items to scale the two tests together. The second analysis employs a 2-dimensional Rasch scaling usin...

An analysis component recognizing addresses on printed documents and identifying the respective sender or recipient is presented. The component’s kernel is a standard chart parser for feature-based context-free grammars. The parsing procedure is enhanced with the island-parsing strategy and the ability for partial parsing. The needs of the realworld application within document analysis of print...

Normal-distribution-based maximum likelihood (ML) and multiple imputation (MI) are the two major procedures for missing data analysis. This article compares the two procedures with respects to bias and efficiency of parameter estimates. It also compares formula-based standard errors (SEs) for each procedure against the corresponding empirical SEs. The results indicate that parameter estimates b...

Cosmic strings are a well-motivated extension to the standard cosmological model and could induce a subdominant component in the anisotropies of the cosmic microwave background (CMB), in addition to the standard inflationary component. The detection of strings, while observationally challenging, would provide a direct probe of physics at very high-energy scales. We develop a framework for cosmi...

Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...

DataFrames.jl is a package written for and in the Julia language offering flexible efficient handling of tabular data sets memory. Thanks to Julia's unique strengths, it provides an appealing set features: Rich support standard processing tasks excellent flexibility efficiency more advanced non-standard operations. We present fundamental design how compares with implementations frames other lan...

BACKGROUND Inframammary fold reconstruction has scarcely been evaluated in literature. No biomechanical analyses have been performed comparing different reconstructive methods. This evaluation compares the gold-standard suture reconstruction with an intrarib anchor system (Micro BioComposite SutureTak, Arthrex). METHODS Three analysis groups were compared including 8 Sawbone blocks, 22 embalm...
