BACKGROUND In patients with left ventricular hypertrophy (LVH), LV midwall fractional shortening (FS) is used as a measure of LV systolic performance that is more physiologically appropriate than conventional FS. For evaluation of LV volume and ejection fraction (EF), 2-dimensional (2D) echocardiography is more accurate than M-mode echocardiography. The purpose of this study was to assess systo...

PURPOSE To identify facilitators and barriers among early adopters of Enhance(®)Fitness (EF), in Young Men's Christian Association-affiliated (Y-affiliated) sites from the perspective of program staff. EF is an evidence-based group exercise program for seniors. METHODS This qualitative study used semi-structured phone interviews with 15 staff members representing 14 Y-affiliated sites. Interv...

The translation elongation factor EF-Tu is a GTPase that delivers amino-acylated tRNAs to the ribosome during the elongation step of translation. EF-Tu/GDP is recycled by the guanine nucleotide exchange factor EF-Ts. Whereas EF-Ts is lacking in S. cerevisiae, both translation factors are found in S. pombe and H. sapiens mitochondria, consistent with the known similarity between fission yeast an...

Executive function (EF) deficits in schizophrenia (SZ) are well documented, although much less is known about patterns of EF deficits and their association to differential impairments in everyday functioning. The present study empirically defined SZ groups based on measures of various EF abilities and then compared these EF groups on everyday action errors. Participants (n = 45) completed vario...

The EF-hand protein with a helix-loop-helix Ca(2+) binding motif constitutes one of the largest protein families and is involved in numerous biological processes. To facilitate the understanding of the role of Ca(2+) in biological systems using genomic information, we report, herein, our improvement on the pattern search method for the identification of EF-hand and EF-like Ca(2+)-binding protei...

BACKGROUND Elongation factor G (EF-G) catalyzes the translocation step of translation. During translocation EF-G passes through four main conformational states: the GDP complex, the nucleotide-free state, the GTP complex, and the GTPase conformation. The first two of these conformations have been previously investigated by crystallographic methods. RESULTS The structure of EF-G-GDP has been r...

This article introduces Evaluation-Function based Proof– Number Search (EF-PN) and its second-level variant EF-PN. It is a framework for setting the proof and disproof number of a leaf node with a heuristic evaluation function. Experiments in LOA and Surakarta show that compared to PN and PN, which use mobility to initialize the proof and disproof numbers, EF-PN and EF-PN take between 45% to 85...

—Recently it was shown that Shannon entropy is more Bahadur ef cient than any Rényi entropy of order > 1: In this paper we shall show that relative Bahadur ef ciency between any two Rényi entropies of orders 2 ]0; 1] is 1 when the relative Bahadur ef ciency is de ned according to [1]. Despite the fact that the relative Bahadur ef ciency is 1 it is shown that in a certain sense Shannon entropy i...
