Nonparametric methods provide a flexible framework for estimating the probability density function of random variables without imposing a strict parametric model. By relying directly on observed data, ...

Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is ...

Of late, Analytical Quality by Design (AQbD) has been gaining increased acceptance in the industrial, academic and regulatory circles. Considered as a science and risk-based approach, AQbD provides ...

Powder is a collection of single solid particles, which in most cases may be considered a basic unit. Powder is typically comprised of solid particles, interparticle voids, as well as open and closed ...

Density functional theory (DFT) is a widely used computational method for carrying out quantum calculations in chemistry, materials science, and biology research. Despite its enormous popularity and ...

Background: Measurement of bone mineral density is widely used to diagnose osteoporosis. The objectives of this study are to determine how bone densitometry affects subsequent treatment of osteopenia ...
