conclusions in this study there is no correlation between the main lv diastolic indices derived by spect and echocardiography, may be due to the main changes in the last version of guidline for assessment of lv diastolic function by echocardiography. results the population study consisted of 19 male and 30 female with the average age of 58.2 years.there is a mild negative correlation between pf...

BACKGROUND Dexamethasone (Dex) limits and all-trans-retinoic acid (RA) promotes alveolarization. While structural changes resulting from such hormonal exposures are known, their functional consequences are unclear. METHODS Neonatal rats were treated with Dex and/or RA during the first two weeks of life or were given RA after previous exposure to Dex. Morphology was assessed by light microscop...

To study the left atrial function after cardioversion, left ventricular apex cardiogram, electrocardiogram, unipolar and bipolar oesophageal electrocardiogram, and cardiac catheterization were done after 39 procedures in 37 patients with rheumatic heart disease and 2 with atrial septal defect. An 'a' wave in the apex cardiogram representing left atrial contraction appeared in 31 of the 32 recor...

A cascade correlation learning architecture has been devised for the first time for radial basis function processing units. The proposed algorithm was evaluated with two synthetic data sets and two chemical data sets by comparison with six other standard classifiers. The ability to detect a novel class and an imbalanced class were demonstrated with synthetic data. In the chemical data sets, the...

Gaussian network model (GNM) is one of the most accurate and efficient methods for biomolecular flexibility analysis. However, the systematic generalization of the GNM has been elusive. We show that the GNM Kirchhoff matrix can be built from the ideal low-pass filter, which is a special case of a wide class of correlation functions underpinning the linear scaling flexibility-rigidity index (FRI...

BACKGROUND Thyroid dysfunction can be evaluated by measuring serum thyroid stimulating hormone (TSH), total tri-iodothyronine (T3) and total thyroxine (T4) which will establish euthyroidism, hyperthyroidism and hypothyroidism. Fine needle aspiration (FNA) is the diagnostic test of choice in determining whether a nodule is benign or malignant. OBJECTIVE To correlate hormonal levels to FNA cyto...

We present a systematic comparison of some usual estimators of the 2–point correlation function, some of them currently used in Cosmology, others extensively employed in the field of the statistical analysis of point processes. At small scales, it is known that the correlation function follows reasonably well a power–law expression ξ(r) ∝ r−γ. The accurate determination of the exponent γ (the o...

We present the results of a study of the two-point correlation function for a sample of field galaxies taken from the CNOC cluster survey. The sample consists of 144 galaxies within a contiguous region of space subtending 225 square arcminutes. The objects have r-band magnitudes 17.0 ≤ r ≤ 21.7 and redshifts 0.21 ≤ z ≤ 0.53. The median redshift of the sample is z̄ = 0.36. The real space correlat...

The size of this monograph and its moderate price belie the wealth of information contained within its pages. This book is a competent attempt to assemble biochemical and physiological data and correlate these findings with ultrastructure of the rat anterior pituitary. There are twelve chapters. The first two are devoted to definitions and experimental procedures. The next six chapters center a...

Despite their long history in experiment, simulation, and analytical theory, pair correlation functions that describe local order in many-body systems still retain a legacy of mathematical mysteries. One such open question concerns “realizability” of a given candidate pair correlation function, namely whether it actually represents the pair correlation for some spatial distribution of particles...
