Elastic tensor of Sr2RuO4
The six independent elastic constants of Sr2RuO4 were determined using resonant ultrasound spectroscopy on a high-quality single-crystal specimen. The constants are in excellent agreement with those obtained from pulse-echo experiments performed on a sample cut from the same ingot. A calculation of the Debye temperature using the measured constants agrees well with values obtained from both spe...
متن کاملLP Relaxation for Elastic Matching
According to [2], in this paper we discuss a new method to match two 3D shapes in a geometrically consistent way. We understand a matching as a diffemorphism and want to find the matching that minimizes the physical energy that is necessary to deform one shape into the other. Because of the fact that diffeomorphisms can be completely characterized by their graph, we propose an equivalent formul...
متن کاملAnalysis of partial volume effects in diffusion-tensor MRI.
The diffusion tensor is currently the accepted model of diffusion in biological tissues. The measured diffusion behavior may be more complex when two or more distinct tissues with different diffusion tensors occupy the same voxel. In this study, a partial volume model of MRI signal behavior for two diffusion-tensor compartments is presented. Simulations using this model demonstrate that the con...
متن کاملMeasurements of the Quasi-Elastic and Elastic Deuteron Tensor Asymmetries
In this update to PR12-15-005 and LOI12-14-002, we propose the first measurement of the tensor asymmetry Azz in the quasi-elastic region through the tensor polarized D(e, e )X channel; an asymmetry that is sensitive to the nucleon-nucleon potential at short distances. Previous measurements of Azz have been used to extract b1 in the DIS region and T20 in the elastic region. A unique feature of t...
متن کاملTensor decomposition in electronic structure calculations on 3D Cartesian grids
Modern problems of physical chemistry lead to computations of many-particle potentials and related integral transforms, involving quantities described by higher-order tensors. Conventional numerical treatment of these problems suffers from the so-called “curse of dimensionality”. Recently developed Tucker and canonical tensor approximation techniques provide structured data-sparse representatio...
