Development of Intelligent Water Distributor for Horizontal Well
Shiyou jixie, 2017 Considering that the separate section water injection for horizontal well stimulation is still in the preliminary exploration stage, and there are some problems such as high cost of measurement and adjustment in the later period and incapable of ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...

Methodology for horizontal well pattern design in anisotropic oil reservoirs
Petroleum Exploration and Development, 2008 Anisotropic permeability has major effects on horizontal well networks. Well lines, horizontal sections of the wells, and the principal direction of anisotropic permeability should be parallel or perpendicular to each other, in which the horizontal well ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We
