Arbitrary choice of basic variables in density functional theory: Formalism [PDF]
The Hohenberg-Kohn theorem of the density functional theory is extended by modifying the Levy constrained-search formulation. The new theorem allows us to choose arbitrary physical quantities as the basic variables which determine the ground-state properties of the system. Moreover, the theorem establishes a minimum principle with respect to variations

Unconditional basic sequences in spaces of large density [PDF]
We study the problem of the existence of unconditional basic sequences in Banach spaces of high density. We show, in particular, the relative consistency with GCH of the statement that every Banach space of density $\aleph_ω$ contains an unconditional basic sequence.

The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]
We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

The imprint of crustal density heterogeneities on regional seismic wave propagation [PDF]
Density heterogeneities are the source of mass transport in the Earth. However, the 3-D density structure remains poorly constrained because travel times of seismic waves are only weakly sensitive to density.

Global imaging of the Earth's deep interior: seismic constraints on (an)isotropy, density and attenuation [PDF]
Seismic tomography is the principal tool to probe the deep interior of the Earth. Models of seismic anisotropy induced by crystal alignment provide insight into the underlying convective motion, and variations of density allow us to discriminate between ...

Basic personality traits and density distributions of basic personality states
Perspective on personality based on multiple assessments of momentary personality states has been gaining increased research attention. Personality states can be viewed as everyday manifestations of personality in behavior and, when assessed throughout different occasions, they form density distributions with their own parameters. The aim of this study
