Observations on the Relation of the Virus Causing Rabbit Papillomas to the Cancers Deriving Therefrom
The papillomas caused by the Shope virus sometimes grow down spontaneously into the subcutaneous tissue and extend along the lymphatics in the same way as do many cancers of the human breast. They may even invade the voluntary muscle under such circumstances, taking on an aspect suggestive of squamous cell carcinomatosis, but ultimately they differentiate in the way characteristic of the papill...
متن کاملChildren's causal inferences from conflicting testimony and observations.
Preschoolers use both direct observation of statistical data and informant testimony to learn causal relationships. Can children integrate information from these sources, especially when source reliability is uncertain? We investigate how children handle a conflict between what they hear and what they see. In Experiment 1, 4-year-olds were introduced to a machine and 2 blocks by a knowledgeable...
متن کاملInferences on the Generalized Variance under Normality
Generalized variance is applied for determination of dispersion in a multivariate population and is a successful measure for concentration of multivariate data. In this article, we consider constructing confidence interval and testing the hypotheses about generalized variance in a multivariate normal distribution and give a computational approach. Simulation studies are performed to compare thi...
متن کاملObservations upon Tropical Fishes and Inferences from their Adaptive Coloration.
tribution and more or less evanescent in continuity, to the streams that flowed constantly in one direction and eventually into an unnatural habitat, the sea. They needed a more direct and quicker embryonic development, requiring, it would seem, the abandonment of the nauplius stage. It may therefore well be that the trilobites retaining the nauplius stage did not give rise to these stocks, as ...
متن کاملA Survey of Table Recognition: Models, Observations, Transformations, and Inferences
Table characteristics vary widely. Consequently, a great variety of computational approaches have been applied to table recognition. In this survey, the table recognition literature is presented as an interaction of table models, observations, transformations and inferences. A table model defines the physical and logical structure of tables; the model is used to detect tables, and to analyze an...
