متن کاملAquatic Alchemy
Background: Current statistical methods for sib-pair linkage analysis of complex diseases include linear models, generalized linear models, and novel data mining techniques. The purpose of this study was to further investigate the utility and properties of a novel pattern recognition technique (step-wise discriminant analysis) using the chromosome 10 linkage data from the Framingham Heart Study...
متن کاملModern Alchemy
developmental process. Surveying the mathematical analysis of Woodger and the contribution of experimental embryology to formation (Gestaltung), to segregation, to differentiation, to growth, to polarity and symmetry, and finally to regeneration, we are led through a consideration of the historical character of the organism to the system theory. We read, "We must view the germ as a whole, as a ...
متن کاملCreating new β cells: cellular transmutation by genomic alchemy.
To address insulin insufficiency, diabetes research has long focused on techniques for replacing insulin-producing β cells. Studies in mice have suggested that, under some conditions, α cells possess the capacity to transdifferentiate into β cells, although the mechanisms that drive this conversion are unclear. In this issue, Bramswig et al. analyzed the methylation states of purified human α, ...
متن کاملAtomic Alchemy
We consider the transitions between electromagnetic bound states, such as the exclusive weak decay of a muonic atom into an electronic atom: (µ − Z) → (e − Z)¯ ν e ν µ. We show that relativistic effects in the atomic wave-functions are crucial for determining the rate. In the case of heavy atoms, the exclusive channel branching ratios exceed 10 −6 , possibly bringing the study of these rare dec...
