The role of the density gradient on intermittent cross-field transport events in a simple magnetized toroidal plasma
Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Mario Ludovico Podesta, Francesca Maria Poli
Intermittent cross-field particle transport events (ITEs) are studied in the basic toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)], with focus on the role of the density gradient. ITEs are due to the i ...
2008Eikonal approximation in AdS/CFT: Conformal partial waves and finite N four-point functions
We introduce the impact parameter representation for conformal field theory correlators of the form A similar to (O1O2O1O2). This representation is appropriate in the eikonal kinematical regime, and approximates the conformal partial wave decomposition in ...
Elsevier Science Bv2007Scalar relativistic correction to nucleus-independent chemical shifts of coinage-metal compounds: How does the pseudopotential approximation perform?
The performance of commonly used pseudopotentials for calcns. of nucleus-independent chem. shifts (NICS) at the center of coinage-metal rings (M4Li2 (D4h), M = Cu, Ag, Au) was studied. The scalar relativity, which has a nonnegligible effect on NICS, is acc ...
2006Design of Steerable Filters for Feature Detection Using Canny-Like Criteria
We propose a general approach for the design of 2D feature detectors from a class of steerable functions based on the optimization of a Canny-like criterion. In contrast with previous computational designs, our approach is truly 2D and provides filters tha ...
IEEE2004Sample restriction using magnetic field gradients in high-resolution solid-state NMR
Many solid-state NMR experiments are sensitive to inhomogeneity in the radiofrequency field. We propose a method to restrict the sample volume, in magic angle spinning experiments, using a static magnetic field gradient and a selective pulse. The position ...
ACADEMIC PRESS INC2000Electrodynamics in complex systems: Application to near-field probing of optical microresonators
This paper. discusses recent theoretical efforts to develop a general and flexible method for the calculation of the field distributions around and inside complex optical systems involving both dielectric and metallic materials. Starting from the usual lig ...
1996Equilibrium Gradient Effects in the Theory of Alfven-Wave Heating
An explicit expression for the local power absorption density in a uniformly-magnetized slab plasma is derived from the Vlasov-Maxwell equations, taking into account density and temperature gradients. Using a transformation to Lagrangian coordinates, the k ...
