State-of-the-art CTA imaging equipment has increased increased clinician's ability to make non-invasive diagnoses of coronary heart disease; however, an effective interpretation of the cardiac CTA becomes cumbersome due to large amount of imaged data. Intensity based background suppression is often used to enhance the coronary vasculature but setting a fixed threshold to discriminate coronaries...

Describing the relationship between vehicle volume and travel time delay on road sections consisting multiple intersections in the context of junction quantity is favorable to extend the advantage of intersection-specific volume-delay functions. This paper demonstrates a microsimulation method combined with a non-linear function fitting algorithm to determine unbiased delay function parameters ...

The apparent partial specific volume, phi, of a protein (or other macromolecule) and the absolute concentration, c, can be determined from the densimetry of solutions and diffusates in 1H2O , 2H2O and 1H2O/2H2O mixtures if the ratios of concentrations (relative concentrations) are known. The densimetry method allows a non-destructive check on total macromolecule concentrations without prior kno...

BACKGROUND Finasteride was introduced to treat patients with benign prostatic hyperplasia (BPH) recently, and it has shown its effects in reduction of prostate volume and decrease of prostate-specific antigen (PSA). We want to know how and how much does finasteride affect prostate volume as well as PSA and prostate-specific antigen density (PSAD), since PSA and PSAD are widely used as screening...

BACKGROUND Prostate is an important male reproductive system gland and its disorders can affect men's quality of life and health. Prostatitis, benign prostatic hyperplasia (BPH), and prostate adenocarcinoma are major disorders that can be found in all men in different ages. OBJECTIVES The aim of this study was to investigate the association of diet with serum prostate specific antigen (PSA) l...

calculate some thermodynamic properties of molten polymers including specific volume and isothermal compressibility (s.m. hoseini, physical chemistry & electrochemistry, 2 (2014) 56-65). this work extended that eos to predict the volumetric properties of some molten ethylene copolymers including ethylene/1-octene, ethylene/1-butene (xethylene equal to 0.8543 and 0.563), ethylene/propene. the ab...

Background: To evaluate the role of 3D, 4D and color Doppler ultrasound (US) in the assessment of early human development. Materials and Methods: 380 women with uncomplicated early pregnancy between 5 and 14 weeks were evaluated by 3D, 4D and color Doppler US. Results: Regression analysis revealed exponential rise of the gestational sac volume with gestational age throughout the first trimester...

The unwanted radiation transmission through the multileaf collimators could be reduced by the jaw tracking technique which is commercially available on Varian TrueBeam accelerators. On the basis of identical plans, this study aims to investigate the dosimetric impact of jaw tracking on the volumetric-modulated arc therapy (VMAT) plans. Using Eclipse treatment planning system (TPS), 40 jaw-track...
