International Journal of Peptide and Protein Research, 1979
The calculation of protein densities from atomic coordinates is not straightforward and requires very careful attention to the determination of the protein‐solvent boundary. Interior densities are more readily obtained and are in reasonable agreement with those estimated from solvent accessibility studies.The interior of globular proteins has very ...

Mammographic density (MD) refers to the radiographic density of the breast on the mammogram. The risk of developing breast cancer is 4–5 times higher for women with the highest compared to lowest MD. The increased risk is related to biological mechanisms and the decreased sensitivity of mammography in women with dense breast (tumour masking effect). MD

Theory of Probability & Its Applications, 1994
Summary: This paper shows that a uniform expression is possible for stable densities (in all cases except \(p = 1\), \(\gamma = 0\) in terms of the incomplete hypergeometric function \(_ 1 G_ 0(\alpha,\beta,z)\) defined by \[ _ 1G_ 0(\alpha,\beta,z)=\begin{cases} {1\over\Gamma(\alpha)}\sum^\infty_{n=0} {\Gamma(\alpha + n\beta)\over n!} z^ n, & \text{if

Density Operator, Density Matrix
2011The density matrix is especially suited for a description of an arbitrary (pure or mixed) polarization state (differently from a wave function). With it averages and expectation values as well as statistical distributions of measurable quantities can be described.

Physical Review Letters, 1992
Since the inception of Density Functional Theory (DFT) the remarkable success of the Local Density Approximation (LDA) has been difficult to improve in a systematic way. Originally Hohenberg, Kohn and Sham introduced LDA as the first term in a gradient expansion of the exchange-correlation energy functional[1].

Density and Density Matrices in Density Functional Theory
1990Publisher Summary This chapter discusses density and density matrices in density functional theory. It also discusses particle number and order; fundamental Hilbert spaces; matrices and restricted operators; local and nonlocal operators; equidensity orbitals and n representability; and negative consequences of a finite model.

Relative Density -> Eco-Density
2009Non se ne può fare a meno. La sua assenza produce di solito il vuoto, che per quando rarefatto è sempre in qualche modo denso di qualcosa. Eppure, per quanto essenziale, la densità è anche sfuggente come gran parte delle caratteristiche qualificative che descrivono proprietà delle sostanze di cui sono fatti i corpi.
