Sex Differences in Mathematics and Science Achievement: A Meta-Analysis of National Assessment of Educational Progress Assessments.

open access: yes, 2014
Gender gaps in the development of mathematical and scientific literacy have important implications for the general public’s understanding of scientific issues and for the underrepresentation of women in science, technology, engineering, and math.

Statistical Aspects of Wasserstein Distances [PDF]

open access: yesAnnual Review of Statistics and Its Application, 2018
Wasserstein distances are metrics on probability distributions inspired by the problem of optimal mass transportation. Roughly speaking, they measure the minimal effort required to reconfigure the probability mass of one distribution in order to recover ...

Remarks on the distributional Schwarzschild geometry [PDF]

open access: yesJ.Math.Phys. 43 (2002) 1493-1508, 2001
This work is devoted to a mathematical analysis of the distributional Schwarzschild geometry. The Schwarzschild solution is extended to include the singularity; the energy momentum tensor becomes a delta-distribution supported at r=0. Using generalized distributional geometry in the sense of Colombeau's (special) construction the nonlinearities are ...

Infinite series involving harmonic numbers and reciprocal of binomial coefficients

open access: yesAIMS Mathematics
Yamamoto's integral was the integral associated with 2-posets, which was first introduced by Yamamoto. In this paper, we obtained the values of infinite series involving harmonic numbers and reciprocal of binomial coefficients by using some techniques of

The Distribution of Prime Numbers [PDF]

open access: yesNature, 2006
THIS interesting “Cambridge Tract” is concerned mainly with the behaviour, for large values of x, of the function n(x), which denotes the number of primes not exceeding x. The first chapter gives some elementary theorems concerning TT(O:), that is to say,

An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

open access: yesFEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in
