Aim. To compare the diagnostic performance of diffusion weighted imaging (DWI) using b-values of 1000 s/mm(2) and 2000 s/mm(2) at 3 Tesla (T) for the evaluation of clinically significant prostate cancer. Matherials and Methods. Seventy-eight prostate cancer patients underwent a 3T MRI scan followed by radical prostatectomy. DWI was performed using b-values of 0, 1000, and 2000 s/mm(2) and quali...

I demonstrate that the B(E2) value in 32Mg can be understood with a model in which both the ground and 2+ first-excited states are predominantly of sd-shell character.

Overview: The characteristics of water diffusion parallel and perpendicular to white matter tracts are a sensitive indicator of tissue microstructure and cannot be fully determined from single b-value DTI. In order to obtain singleor two-tensor DTI data with multiple b-values and acceptable SNR in clinically reasonable times, a new data acquisition strategy is proposed – CURVE-ball DTI (CUbe Ra...

Laboratory experiments have shown that the b value in the size distribution of acoustic emission events decreases linearly with differential stress. There have been a number of observations that indicate that this relation may also hold for earthquakes. Here using a simple frictional strength model for stresses in the continental lithosphere combined with earthquake b values measured as a funct...

The study established the influence of media on adolescents’ sexual risky behaviour. Two hundred (200) Adolescents of reproductive age were selected from five secondary schools in Ibadan Metropolis; Nigeria constituted the sample for the study. Their ages ranged from 12years to17years with a mean age of 14.5years and standard deviation of 3.5. The two instruments used were author-constructed qu...

Gene expression profiles generated by the highthroughput microarray experiments are usually in the form of large matrices with high dimensionality. Unfortunately, microarray experiments can generate data sets with multiple missing values, which significantly affect the performance of subsequent statistical analysis and machine learning algorithms. Numerous imputation algorithms have been propos...

BACKGROUND Hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. Liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. Percutaneous liver biopsy; however, is an invasive procedure with risks of complications. Therefore, there is need for alternative non-invasive techniq...

PURPOSE As MR scanner hardware has improved, allowing for increased gradient strengths, we are able to generate higher b values for diffusion-weighted (DW) imaging. Our purpose was to evaluate the appearance of the normal brain on DW MR images as the diffusion gradient strength ("b value") is increased from 1,000 to 3,000 s/mm2. METHOD Three sets of echo planar images were acquired at 1.5 T i...

In this work the collocation method based on quartic B-spline is developed and applied to two-point boundary value problem in ordinary differential equations. The error analysis and convergence of presented method is discussed. The method illustrated by two test examples which verify that the presented method is applicable and considerable accurate.
