    White matter changes in dementia of Alzheimer's type: the difference in vulnerability between cell compartments (1990)

    Notes: Structural white matter changes were found to be common in dementia of Alzheimer's type. A neuropatholoical investigation was undertaken in order to characterize and quantify these white matter changes. The tissue changes were compared with those in white matter in normal control cases and in complete white matter infarcts. Our results support the hypothesis that the white matter lesion seen in dementia of Alzheimer's type is due to incomplete infarction involving both axons and myelin and is a result of mild ischaemia. In mild ischaemia, the myelin compartment appears to be the most vulnerable. We have termed the lesion selective incomplete white matter infarction.

    The effects of sampling design parameters on block selection (1992)

    Notes: Abstract Cost-effective spatial sampling strategy requires balancing sampling costs with the expected benefits from improved information. A contaminated site numerical model was used to test various single-phase sampling schemes, which were evaluated based on the quality of block selections from interpolated values. Different sample set sizes, different sampling patterns, and two levels of sampling precision were used. The sample set size was the only one of these factors observed to be significant. Bias was also examined. Modest levels (〈20%) had minimal impact; the effects of higher levels of bias varied with the selection level concentration.
