Multiple myeloma is an incurable cancer with expansion of malignant plasma cells in the bone marrow. Previous studies have shown that monocytes and macrophages in the bone marrow milieu are important for tumor growth and may play a role in the drug response. We therefore characterized monocytes in bone marrow aspirates by flow cytometry. We found that there was significant correlation between t...
This paper presents an element of Artificial Intelligence (AI) system to assist operators with the management traffic in orbit. The is based on a classification collision events using Dempster–Shaffer’s theory Evidence (DSt). DSt proposed capture and quantify epistemic uncertainty estimation Probability Collision (PC). By capturing calculation PC, we mitigate paradoxical Dilution that affects u...
Phosphatidyl-N,N-dimethylethanolamine (PDME), an intermediate in the formation of phosphatidylcholine (PC) by the sequential methylation of phosphatidylethanolamine (PE), was purified from rat brain and its fatty acid (FA) composition compared with those of brain PC and PE. The proportion of polyunsaturated fatty acids (PUFAs) in the PDME (29.8%) was similar to that of PE (27.7%) and much great...
A method is presented to estimate the accuracy of automated classification systems using only expert ratings that may be substantially less accurate than the systems being evaluated. The estimation method begins with multiple expert ratings on test cases, uses the level of inter-rater agreement to estimate rater accuracy, uses Bayesian updating based on estimated rater accuracy to estimate a “g...
OBJECTIVE To assess the effectiveness of a teacher led intervention to improve teenagers' knowledge about emergency contraception. DESIGN Cluster randomised controlled trial. SETTING 24 mixed sex, state secondary schools in Avon, south west England. PARTICIPANTS 1974 boys and 1820 girls in year 10 (14-15 year olds). INTERVENTION Teachers gave a single lesson on emergency contraception t...
Population size for EvolutionaryAlgorithms is usually an empirical parameter. We study the population size from aspects of fitness landscapes’ ruggedness and Probably Approximately Correct (PAC) learning theory.
In a previous report it was shown that the replacement of native erythrocyte phosphatidylcholine (PC) with different PC species which have defined acyl chain compositions can lead to morphological changes (Kuypers, F.A., W. Berendsen, B. Roelofsen, J. A. F. Op den Kamp, and L.L.M. van Deenen, 1984, J. Cell Biol., 99:2260-2267). It was proposed that differences in molecular shape between the int...
