A cohort study is the best way to identify incidence and natural history of a disease, and c...
متن کاملMarching Simplices
A multi-dimensional algorithm for surface extraction from a structured domain is presented. Topological information is used to split the n-cubes into simplices which are used to extract the possible configurations of new surface elements. The algorithm is intended to complement to the existing surface extraction algorithms, which are specialized to deal with a set dimension, while this algorith...
متن کاملMarching ridges
Marching Ridges is an algorithm for finding ridges of measurement functions defined for images, in which the ridges are defined as level sets of first derivatives of the measurement functions. Marching Ridges is both specific in its application to 2D and 3D medical images for the purpose of finding cores, and general in its theoretical application to finding ridges of intensity, boundary and me...
متن کاملPerspective: cohort studies.
This issue of Epidemiologic Reviews on cohort studies is published five decades after the initiation of the Framingham study, one of the landmark investigations of epidemiologic research and, more generally, contemporary biomedical research. Within a few years other cohort studies—for example, of British physicians and of the atomic bomb survivors—were initiated. As follow-up of the participant...
