Further Studies of Polymers as Carcinogenic Agents
The inception of this investigation is an exam ple of serendipity, a word recently popularized to designate the faculty of accidentally making ob servations or discoveries which were not originally sought. In the present instance, a safe antihyper tensive compound was being sought among the quinones to reduce the high blood pressure pro duced by wrapping one or both kidneys of rats with celloph...
متن کاملExpectation-Maximisation Algorithm Derivation and a cookbook for further recepies
To simplify the treatment, we consider here only how to derive and apply the expectation-maximisation algorithm in the context of soft clustering. The treatment of other applications is analogous. The soft-clustering is based on a probabilistic model, which combines k different data sources. More precisely, we assume that individual observations x1, . . . ,xn are generated by k different data s...
متن کاملFrom Commodity Polymers to Functional Polymers
Functional polymers bear specified chemical groups, and have specified physical, chemical, biological, pharmacological, or other uses. To adjust the properties while keeping material usage low, a method for direct synthesis of functional polymers is indispensable. Here we show that various functional polymers can be synthesized by in situ cross-linked polymerization/copolymerization. We demonst...
متن کاملAn Introduction to Expectation-Maximization
This notes reviews the basics about the Expectation-Maximization (EM) algorithm, a popular approach to perform model estimation of the generative model with latent variables. We first describe the E-steps and M-steps, and then use finite mixture model as an example to illustrate this procedure in practice. Finally, we discuss its intrinsic relations with an optimization problem, which reveals t...
متن کاملFurther Inequalities for the Expectation and Variance of a Random Variable Defined on a Finite Interval
Some new elementary inequalities for the expectation and the variance of a continuous random variable defined on a finite interval are given. Mathematics subject classification (2000): 26D15, 60E15.
