Regional Centroid-Moment-Tensor Analysis for Earthquakes in Canada and Adjacent Regions: An Update

Seismological Research Letters, 2012
Reliable determination of earthquake source parameters is a subject of fundamental importance for seismological research. It also provides critical observational constraints to the study of deformation and stress within the lithosphere. A comprehensive catalog of earthquake source parameters is not only essential to the understanding of global and ...

On the interaction of adjacent hot plasma streams. I. Dielectric permeability tensor components

Plasma Physics, 1971
The expressions for the components of the dielectric permeability tensor of a relativistic plasma stream have been obtained. The parameters (density, longitudinal temperature and equilibrium velocity) of the plasma stream varies over the cross-section of the stream which moves along an external magnetic field.

Intraoperative Neuronavigation Using Diffusion Tensor MR Tractography for the Resection of a Deep Tumor Adjacent to the Corticospinal Tract

Stereotactic and Functional Neurosurgery, 2005
<i>Objective and Importance:</i> Delineation of cerebral white matter tracts using MR tractography adds essential information for planning intracranial surgery. Integrating tractography with intraoperative neuronavigation may reduce the likelihood of new neurological deficits after surgery done to remove tumors adjacent to the projection ...

Surgery of lesions lying within or adjacent to the pyramidal tract using preoperative diffusion tensor imaging and FMRI and neuronavigation

2021
Objective: Surgery within or close to the pyramidal tract demands special attention to avoid permanent plegia. To maximize the extent of resection during surgery within or adjacent to this area, a detailed functional mapping of these areas is necessary. Methods: DTI was used with 1.9 mm slices [for full text, please go to the a.m. URL]

Correlation between diffusion tensor imaging parameters of the distal femoral physis and adjacent metaphysis, and subsequent adolescent growth

Pediatric Radiology, 2019
Diffusion-tensor imaging (DTI) depicts the movement of water through columns of cartilage and newly formed bone and provides information about velocity of growth and growth potential.To determine the correlation between DTI tractography parameters of the distal femoral physis and metaphysis and the height change after DTI in pubertal and post-pubertal ...

Update of Regional Moment Tensor Analysis for Earthquakes in New Zealand and Adjacent Offshore Regions

Bulletin of the Seismological Society of America, 2013
Abstract New Zealand is one of the more seismically active countries in the world with over 15,000 earthquakes each year in New Zealand and the adjacent offshore region. Routine regional moment tensor (RMT) analysis was implemented by GeoNet in 2007, and nearly 1300 RMT solutions have been calculated for the New Zealand region from August 2003 through

Subcortical Alterations in Tissue Microstructure Adjacent to Focal Cortical Dysplasia: Detection at Diffusion-Tensor MR Imaging by Using Magnetoencephalographic Dipole Cluster Localization

Radiology, 2009
To determine whether changes at diffusion-tensor magnetic resonance (MR) imaging were present in children with intractable epilepsy and focal cortical dysplasia (FCD) in (a) subcortical white matter subjacent to MR imaging-visible areas of FCD, (b) subcortical white matter beyond the MR imaging-visible abnormality but subjacent to a ...

Adjacency preserving functions on symmetric elements and linear preservers of non-zero decomposable symmetric tensors

Linear and Multilinear Algebra, 2009
Let A be a non-empty set and m be a positive integer. Let ≡ be the equivalence relation defined on A m such that (x 1, …, x m ) ≡ (y 1, …, y m ) if there exists a permutation σ on {1, …, m} such that y σ(i) = x i for all i. Let A (m) denote the set of all equivalence classes determined by ≡. Two elements X and Y in A (m) are said to be adjacent if (x 1,

Changes in fiber integrity, diffusivity, and metabolism of the pyramidal tract adjacent to gliomas: a quantitative diffusion tensor fiber tracking and MR spectroscopic imaging study.

AJNR. American journal of neuroradiology, 2007
The underlying changes in the neuronal connectivity adjacent to brain tumors cannot always be depicted by conventional MR imaging. The hypothesis of this study was that preoperative sensorimotor deficits are associated with impairment in pyramidal fiber bundles.
