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...
We analyze the problem of calculating the solutions and the spectrum of a string with arbitrary density and fixed ends. We build a perturbative scheme which uses a basis of WKB-type functions and obt...
A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1

We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...
Effect of Potential Shape on the Density of the Impurity States in Nanotube
Subbands mixing Magnetic field Density impurity states Binding energy

We analyze the effect of the potential shape on the ground state energy of the off-axis neutral donor in GaAs/Ga1¡xAlxAs cylindrical nanotube in the presence of the uniform magnetic field applie...
Role of Sn in the Density of Defect States in a-Se0.75Te0.25 and a-Se0.85Te0.15Thin Films
Thin films Chalcogenide glasses SCLC DOS

In this paper we report the effect of Sn incorporation in the density of defect states of two binary Se-Te glassy systems, comparing the properties of a-Se0.75Te0.25, a-Se0.85Te0.15 and a-Se0.75Te0.15...
QCD at High Parton Density
QCD High Parton Density
2010/10/26
The high parton density regime of Quantum Chromodynamics (QCD) is briefly discussed. Some phenomenological aspects of saturation are described, mainly focusing on possible signatures of the non-linear...
Dielectric Constant and Density of Water as a Function of Pressure at Constant Temperature
Water Constant Temperature Dielectric Constant Density of Water

In order to simulate the effects of hydrostatic pressure on protein folding/unfolding it is necessary to accurately describe the behavior of the dielectric constant and the density of the solvent (wat...
