Misunderstandings, misperceptions, and mistakes.
iscussions about evidence-based medicine (EBM) have engendered both positive and negative reactions from clini-cians, researchers, and policymakers since the term was first coined in the early 1990s (1, 2). These discussions were brought to the forefront again in a recent commentary by Dr. Bernadine Healy, former Director of National Institutes of Health (NIH), in US News and World Report(3). S...
متن کاملA Zq-Fan theorem
In 1952, Ky Fan proved a combinatorial theorem generalizing the Borsuk-Ulam theorem stating that there is no Z2-equivariant map from the d-dimensional sphere S to the (d − 1)-dimensional sphere Sd−1. The aim of the present paper is to provide the same kind of combinatorial theorem for Dold's theorem, which is a generalization of the Borsuk-Ulam theorem when Z2 is replaced by Zq, and the spheres...
متن کاملFan Selection and Maintenance
J.F. Smith Animal Sciences and Industry Kansas State University When reducing heat stress in dairy herds, fans are used to enhance the evaporation of moisture from a cow’s back. Fan selection should be based on performance rather than horsepower and diameter. Certified lab studies of similar size fans show a 50 percent difference in airflow rate per unit of input energy. Maintenance is importan...
متن کاملA Non-Regular Grobner Fan
The Gröbner fan of an ideal I ⊂ k[x1, . . . , xn], defined by Mora and Robbiano, is a complex of polyhedral cones in Rn. The maximal cones of the fan are in bijection with the distinct monomial initial ideals of I as the term order varies. If I is homogeneous the Gröbner fan is complete and is the normal fan of the state polytope of I. In general the Gröbner fan is not complete and therefore no...
متن کاملUsability assessment of cone beam computed tomography with a full-fan mode bowtie filter compared to that with a half-fan mode bowtie filter
Background: In intensity modulated radiation therapy, cone beam computed tomography (CT) has been used to evaluate patients prior to treatment. This study conducted a comparative evaluation of the image reconstruction ability of the clinically used half-fan bowtie filter and the full-fan bowtie filter. Materals and Methods: A CT simulation marker was inserted inside a human phantom, and the pel...
