ABSTRACT Straightened cylindrical models of coronal loops have been standard for decades, and shown to support nanoflare-like heating, but the influence geometric curvature in upon heating produced has not discussed depth. Heating, its spatiotemporal distributions, associated mechanisms responsible are discussed, compared with those from straightened a loop. Previously, magnetohydrodynamic aval...

The influence of space charge on emittance growth is studied in simulations of a coasting beam exposed to a strong octupolar perturbation in an otherwise linear lattice, and under stationary parameters. We explore the importance of selfconsistency by comparing results with a non-self-consistent model, where the space charge electric field is kept “frozen-in” to its initial values. For Gaussian ...

Abstract. More detailed observational capabilities in the microwave (MW) range and advancements details of microphysical schemes for ice snow demand increasing complexity to be included scattering databases. The majority existing databases rely on discrete dipole approximation (DDA) whose high computational costs limit either variety particle types or parameters included, such as frequency, tem...

Data described by econometric models typically contains autocorrelation and/or heteroskedasticity of unknown form and for inference in such models it is essential to use covariance matrix estimators that can consistently estimate the covariance of the model parameters. Hence, suitable heteroskedasticity-consistent (HC) and heteroskedasticity and autocorrelation consistent (HAC) estimators have ...

Spontaneous fission barriers, quadrupole inertia tensor, and zero-point quadrupole correlation energy are calculated for 252,256,258 Fm in the framework of the self-consistent Skyrme-Hartree-Fock+BCS theory. Two ways of computing collective inertia are employed: the Gaussian Overlap Approximation to the Generator Coordinate Method and cranking ansatz. The Skyrme results are compared with those ...

The finite temperature effective potential of the Abelian Higgs Model is studied using the self-consistent composite operator method, which can be used to sum up the contributions of daisy and superdaisy diagrams. The effect of the momentum dependence of the effective masses is estimated by using a Rayleigh-Ritz variational approximation.

Spontaneous fission barriers, quadrupole inertia, and zero-point quadrupole-energy corrections are calculated for 252,256,258 Fm in the framework of the self-consistent Skyrme-Hartree-Fock+BCS theory. Two ways of computing dynamical inertia are employed: the Gaussian Overlap Approximation to the Generator Coordinate Method and crank-ing ansatz. The Skyrme results are compared with those of the ...

A detailed model for the electronic properties of self-assembled InAs/GaAs quantum dots (SADs) is presented, with emphasis on inter-level transitions and many-body effects. The model is based on the self-consistent solution of three-dimensional Poisson and Schrödinger equations within the local (spin-) density approximation. Nonparabolicity of the band structure and a continuum model for the st...
