AIM We have applied diffusion tensor imaging (DTI) to interrogate microstructural changes in white matter integrity in a widely used middle cerebral artery occlusion (MCAO) model of cerebral ischemia. MATERIAL AND METHODS We performed ex vivo DTI 35 days after 60 minutes transient focal ischemia in male spontaneously hypertensive rats and generated fractional anisotropy (FA), mean, axial and ...

Relevant local characteristics of fatigue loading are the largest stress amplitudes in related mean values. They should be determined for whole components. The relevant material properties then compared with stresses to assess integrity and life a panel, made Al allow, welded stringers. To determine maximum Finite Element Method was used.

OBJECTIVE We investigated corticospinal tract (CST) integrity in the absence of white matter (WM) lesions using diffusion tensor imaging (DTI) in early MS disease stages. METHODS Our study comprised 19 patients with clinically isolated syndrome (CIS), 11 patients with relapsing-remitting MS (RRMS), and 32 age- and sex-matched healthy controls, for whom MRI measures of CST integrity (fractiona...

Hippocampal structural integrity is commonly quantified using volumetric measurements derived from brain magnetic resonance imaging (MRI). Previously reported associations with cognitive decline have not been consistent. We investigate hippocampal integrity using quantitative MRI techniques and its association with cognitive abilities in older age. Participants from the Lothian Birth Cohort 193...

Poor social health has been linked to risk of neuropsychiatric disorders. Neuroimaging studies have shown associations between and global white matter microstructural integrity. We aim identify which tracts are involved in these associations. Social markers (loneliness, perceived support, partnership status) integrity 15 (identified with probabilistic tractography after diffusion magnetic reson...

Semantic properties that reflect quality criteria can be modeled by integrity constraints. Violated instances of constraints may serve as a basis for measuring quality. Such measures also serve for monitoring and controlling quality impairment across changes.

We investigate how belief change operations can be eeec-tively constructed. To that end we suppose given a set of laws (alias integrity constraints) together with a relation of dependence between formulas.
