In that case, the calculations are performed using the perturbation method and the compact effective mass density matrix approach.
Metamaterials with highly anisotropic mass density are required for this approach so that it can uncover high-loss scattering on the perforated plastic plates.
The linear mass density of the growing fibers approached a value of two monomers per nm corresponding to single stranded fibers, which is in accordance with presently existing models for the aggregation of β-amyloid.
At the Planck time, the mass density of the universe is thought to approach the Planck density, c5/hG2, roughly 1093 grams per cubic centimetre.
Coming to mass density, on earth the metal with highest mass density is osmium, having a mass density of 22,570 kg/m3.
(ii) The plateau values for the persistence length and linear mass density observed in the final regime are gradually approached from higher values.
The model employs a novel approach via the concept of the effective surface mass density and approximates the unit cell vibrations in the form of piston-like displacements.
The result is intuitively plausible since the smaller the mass density, the smaller the role for gravitation, so the more the universe will approach free expansion (assuming that the cosmological constant is zero).
Central to this research is the desire to surpass the so-called "mass density law", 357 which is a scaling law based on an effective medium approach of estimating the transmission attenuation of an effectively "homogeneous" material.
A density gradient in terms of mass density (g/cm3) versus depth (nm) was obtained from the experimental beam data using a novel approach, yielding a width of the density gradient of approximately 3.5 nm.
