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 density is crucial in manufacturing many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide ...

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 ...

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 ...

Experiments at China's Experimental Advanced Superconducting Tokamak have confirmed the existence of "a density-free region" ...
