Electron structure of topologically disordered metals

Condensed Matter Physics, 2005
Here two methods for calculating the density of states of electrons in conduction band of disordered metals are investigated. The first one is based on the usage of one-parameter trial electron wave function.

FORM FACTORS IN THE FINITE VOLUME [PDF]

International Journal of Modern Physics B, 1999
We study exactly solvable models of quantum statistical mechanics. Our main example is the Quantum nonlinear Schrödinger equation. This model can be solved by algebraic Bethe Ansatz. We are interested in the expression for a form factor of the local field in the finite volume [Formula: see text].

N to Δ electromagnetic transition form factors from lattice QCD

, 2004
The magnetic dipole, the electric quadrupole and the Coulomb quadrupole amplitudes for the transition $\gamma N\to \Delta$ are evaluated both in quenched lattice QCD at $\beta=6.0$ and using two dynamical Wilson fermions simulated at $\beta=5.6$.

Tensor form factor for the D → π(K) transitions with Twisted Mass fermions. [PDF]

, 2018
We present a preliminary lattice calculation of the D → π and D → K tensor form factors fT (q2) as a function of the squared 4-momentum transfer q2.

Value and Variability of Pulse Shape Indicator for Estimating Mean Arterial Pressure in the Radial and Femoral Arteries

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The form factor (FF) is a pulse shape indicator that corresponds to the fraction of pulse pressure added to diastolic blood pressure to estimate the time‐averaged mean arterial pressure (MAP).

Small-Angle Scattering from Weakly Correlated Nanoscale Mass Fractal Aggregates

Nanomaterials, 2019
Formation of fractal aggregates is generally an undesired effect which may lead to end products with worse properties as compared to those of the individual components, especially in nanocomposite materials.

Temperature-Induced Errors in ITTC Model-Ship Extrapolation

Journal of Marine Science and Engineering
This study addresses the question: “Does the towing tank water temperature affect the result of model-ship extrapolation?” While it is well-established that temperature variations affect Reynolds numbers and consequently frictional and viscous resistance,

The Analysis of Periodic Order in Monolayers of Colloidal Superballs

Applied Sciences, 2021
The characterization of periodic order in assemblies of colloidal particles can be complicated by the coincidence of Bragg diffraction peaks of the structure and minima in the form factor of the particles.

Fire as a Soil-Forming Factor [PDF]

AMBIO, 2013
In the span of a human generation, fire can, in theory, impact all the land covered by vegetation. Its occurrence has many important direct and indirect effects on soil, some of which are long-lasting or even permanent. As a consequence, fire must be considered a soil-forming factor, on par with the others traditionally recognized, namely: parent ...
