Comments on Van den Berg, et al. Toxic equivalency factors (TEFs) for PCBs, PCDDs, PCDFs for humans and wildlife. Environ Health Perspect 106:775-792 (1998)

It is shown that some topological equivalency classes of S-unimodal maps are equal to quasisymmetric conjugacy classes. This includes some infinitely renormalizable polynomials of unbounded type.

Abstract The objective of this study was to assess the regulatory framework for health data in Indonesia order understand policy context and explore possibility expanding adoption implementation FAIR Guidelines, which state that should be Findable, Accessible, Interoperable Reusable (FAIR), Indonesia. Although Guidelines were not explicitly mentioned any documents relevant Indonesian digital se...

HYPOTHESIS We hypothesized that review of randomized controlled clinical trials (RCTs) with nonstatistically significant or "negative" results published in the surgical literature do not have appropriate statistical power to demonstrate equivalency between treatment arms. DATA SOURCES AND STUDY SELECTION The MEDLINE database was searched to obtain reports of all RCTs with negative results pub...

The properties of acoustic kinetic energy density and total energy density of sound fields in lightly damped enclosures have been explored thoroughly in the literature. Their increased spatial uniformity makes them more favorable measurement quantities for various applications than acoustic potential energy density (or squared pressure), which is most often used. In this paper, a generalized ac...

Abstract In this paper, we examine the antecedents and consequences of timing in the transition from high school to college. Using the National Education Longitudinal Study of 1988 (NELS:88), we find that 16 percent of high school graduates postpone enrollment by seven months or more after completing high school. Delayers tend to have some common characteristics: they come from families with fe...
