This paper explores two different methods to capture the local anisotropy of locally parallel textures. The corresponding models allow for both an analysis and a synthesis of oriented patterns. The first method models such textures as local oscillations that can be analyzed by a windowed Fourier transform. The resulting model can be sampled by alternating projections that enforce the consistenc...

Formation of an anisotropy lattice in Co/ Pt multilayers by direct laser interference patterning" (2006). Roger Kirby Publications. 2. We report on the use of direct laser interference patterning to form an " anisotropy " lattice in Co/ Pt thin film multilayers. Co/ Pt multilayers have been extensively studied and, for the compositions studied here, are characterized by strong perpendicular mag...

We propose a phenomenological model for incompressible magnetohydrodynamic turbulence. We argue that nonlinear-wave interaction weakens as the energy cascade proceeds to small scales, however, the anisotropy of fluctuations along the large-scale magnetic field increases, which makes turbulence strong at all scales. To explain the weakening of the interaction, we propose that smallscale fluctuat...

Spatial variations in the rigidity of continental plates (expressed in terms of an effective elastic thickness, Te) can have a profound influence on the style of deformation of ocean–continent convergent margins. Depending on the spatial distribution of Te, strains related to plate boundary forces can become concentrated where Te is small. We calculate Te and Te anisotropy in western Canada by ...

We prove higher differentiability of bounded local minimizers to some widely degenerate functionals, verifying superquadratic anisotropic growth conditions. In the two dimensional case, we prove that local minimizers to a model functional are locally Lipschitz continuous functions, without any restriction on the anisotropy.

Abstract For several decades, shear-wave splitting (SWS) parameters (fast polarization orientations and splitting times) have been widely measured to reveal the orientation and strength of mantle anisotropy. One of the most popularly used techniques for obtaining station-averaged SWS parameters is the multiple-event stacking technique (MES). Results from previous studies suggest the splitting t...

Earth’s upper mantle includes a 200 km thick asthenosphere underneath the plates where viscosity and seismic velocities are reduced compared to the background. This zone of weakness matters for plate dynamics and may be required for the generation of plate tectonics itself. However, recent seismological and electromagnetic studies indicate strong heterogeneity in thinner layers underneath the p...

Insulin secretion from islets of Langerhans is a dynamic process that is essential for maintaining glucose homeostasis. The ability to measure dynamic changes in insulin levels upon glucose stimulation from single islets will allow testing of therapeutics and investigating mechanisms of defective secretion observed in metabolic diseases. Most approaches to date for measurement of rapid changes ...

The continuum theory of micromagnetism is used to study ultrathin films with magnetic anisotropy varying laterally on the nanometer scale. A series of infinitely long stripes with alternating inand out-of-plane uniaxial anisotropy is considered as a model for patterned ferromagnetic films. The analytical solution based on an effective anisotropy description of the dipolar energy is given as a f...
