Methodology for horizontal well pattern design in anisotropic oil reservoirs
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 ...

Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...
