TEXTURE ANALYSIS OF IODINE MAPS AND CONVENTIONAL IMAGES FOR K-NEAREST NEIGHBOR CLASSIFICATION OF BENIGN AND METASTATIC LUNG NODULES

Texture analysis of iodine maps and conventional images for k-nearest neighbor classification of benign and metastatic lung nodules

Abstract Background The purpose of this study was to analyze if the use of texture analysis on spectral detector CT (SDCT)-derived iodine maps (IM) in addition to conventional images (CI) improves lung nodule differentiation, when being applied to a k-nearest neighbor (KNN) classifier.Methods 183 cancer patients who underwent contrast-enhanced, ven

Ecosystem respiration, methane and nitrous oxide fluxes from ecotopes in a rewetted extracted peatland in Sweden

Ecosystem respiration (carbon dioxide; CO2), methane (CH4) and nitrous oxide (N2O) fluxes to the atmosphere were determined using an opaque closed chamber method within various ecotopes (vegetation covered, bare peat and open water) in a rewetted extracted peatland and within an adjacent open poor fen in Sweden.Ecotopes had a significant impact on

On a Periodic Solution of the 4-Body Problems

We study the necessary and sufficient conditions on the masses for the dea eyewear periodic solution of planar 4-body problems, where three particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.We prove that the above periodic motion is a solution of Newtonian earthbath facial

A Comparison of Collection Methods for Microbial Volatiles

Recently, there has been an increase in the number of reports that highlight the role of microbes and their volatile metabolites in interactions with plants and insects, including interactions which may benefit agricultural production.Accurate and reproducible volatile collection is crucial to investigations of chemical-mediated communication betwe
