Optimization of Natural Rhenium Irradiation Time to Produce Compositional Radiopharmaceutical
Introduction: Previously, 186Re and 188Re radioisotopes have been produced through appropriate activities, and each of them has been used for therapeutic applications. The 186Re and 188Re have unique properties, which make them proper for the treatment of tumors in different sizes. The long-range 188Re, is suitabl...
متن کاملComparison of time to the event and nonlinear regression models in the analysis of germination data
Extended abstract Introduction: Numerous studies are being carried out to reveal the effects of different treatments on the germination of seeds from various plants. The most commonly used method of analysis is the nonlinear regression which estimates germination parameters. Although the nonlinear regression has been performed based on different models, some serious problems in its structure...
متن کاملCompositional Separate Modular Static Analysis of Programs by Abstract Interpretation
The purpose of this paper is to present four ba sic methods for compositional separate modular static analy sis of programs by abstract interpretation: • Simplification-based separate analysis; • Worst-case separate analysis; • Separate analysis with (user-provided) interfaces; • Symbolic relational separate analysis; as well as a fifth category which is essentially obtained by composition of...
متن کاملStatistical Analysis and Interpretation of Discrete Compositional Data
A composition is a vector of proportions describing the contribution of each of k components to the whole. We introduce an algebra for compositions that provides a natural definition for additive statistical models. The algebra eases interpretation of treatment effects, treatment interactions, and covariates. Our developments extend the logistic normal modeling framework of Aitchison (1982, 198...
متن کاملLinear regression with compositional explanatory variables
Compositional explanatory variables should not be directly used in a linear regression model because any inference statistic can become misleading. While various approaches for this problem were proposed, here an approach based on the isometric logratio (ilr) transformation is used. It turns out that the resulting model is easy to handle, and that parameter estimation can be done like in usual ...
