Relationship between electron density and effective densities of body tissues for stopping, scattering and nuclear interaction of proton and ion beams
electron density body tissues proton and ion beams
2011/9/9
In treatment planning of charged-particle radiotherapy, patient heterogeneity is normally modeled as variable-density water to best reproduce the stopping power. This water-based model would cause sub...
Nuclear symmetry energy at subnormal densities from measured nuclear masses
Nuclear symmetry energy subnormal densities measured nuclear masses
2011/1/6
The symmetry energy coefficients for nuclei with mass number A = 20 ∼ 250 are extracted
from more than 2000 measured nuclear masses. With the semi-empirical connection between the
symmetry ene...
Thermodynamically Consistent Diffuse Interface Models for Incompressible Two-Phase Flows with Different Densities
Diffuse Interface Models Incompressible Two-Phase Flows Different Densities
2010/11/12
A new diffuse interface model for a two-phase flow of two incompressible fluids with different densities is introduced using methods from rational continuum mechanics. The model fulfills local and gl...
On a class of semi-elliptic diffusion models. Part I: a constructive analytical approach for global existence, densities, and numerical schemes (with applications to the Libor market model)
Degenerate parabolic equations financial derivatives sen-sitivities Monte-Carlo methods
2010/4/27
Computational parsimony makes reduced factor Libor market models popular among practioners. However, value functions and sensitivities of such models are described by degenerate parabolic (i.e. semiel...
A model-insensitive determination of First-hitting-time densities with Application to Equity default-swaps
First-hitting-time densities Equity default-swaps
2010/4/27
Equity default-swaps pay the holder a fixed amount of money when the underlying spot level touches a (far-down) barrier during the life of the instrument. While most pricing models give reasonable res...
Statistical Complexity in Traveling Densities
Statistical complexity traveling densities distribution shape
2010/4/7
In this work, we analyze the behavior of statistical complexity in several systems where two identical densities that travel in opposite direction cross each other. The crossing between two Gaussian, ...
A short remark on negative energy densities and quantum inequalities
negative energy densities quantum inequalities
2010/4/7
In quantum field theory it is generally known that the energy density may be negative at a given point in spacetime. A number of papers have shown that there is a restriction on this energy density wh...
