Determination of nonlinear permeability parameters for shear zones in Baihetan Hydropower Station by in-situ tests

Yantu gongcheng xuebao, 2020
Based on the Forchheimer equation of generalized nonlinear permeability, an in-situ test method for determining the permeability parameters of nonlinear flow in shear zones is proposed. Based on the field tests of Baihetan Hydropower Station, it is found

Slow-Light-Enhanced Nonlinear Characteristics in Slot Waveguides Composed of Photonic Crystal Nanobeam Cavities

IEEE Photonics Journal, 2013
We investigate slow-light-enhanced nonlinear characteristics in slot waveguides composed of photonic crystal (PC) nanobeam cavities. To evaluate the effective nonlinear coefficient, numerical simulations are performed by using 3-D vector finite-element ...

Direct Estimation of Nonlinear Aerodynamic Coefficients [PDF]

AIAA Atmospheric Flight Mechanics Conference and Exhibit, 2007
(Abstract) In this paper a parameter estimation technique is proposed which allows for direct updates to the aerodynamic coefficients represented in the form of table lookup. The proposed method is capable of capturing the nonlinearities in the coefficients.

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Use of a Molecular Signature Response Classifier to Inform Treatment Selection Improves Clinical Disease Activity Among Patients with Rheumatoid Arthritis Initiating a Biologic or Targeted Synthetic Disease‐Modifying Antirheumatic Drug

Arthritis Care &Research, EarlyView.
Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of
