Extensional primary field approximations for viscoelastic media
Rheologica Acta, 1971TheTrouton ratio, defined as the ratio of the extensional to the shear viscosity, may reach very high levels in viscoelastic media. Consequently the diagonal components of the deformation rate tensor, often of negligible importance in the analysis of flows ofNewtonian fluids, may be of primary interest here.

Pulsed Field or Conventional Thermal Ablation for Paroxysmal Atrial Fibrillation.
New England Journal of Medicine, 2023BACKGROUND Catheter-based pulmonary vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation, which delivers microsecond high-voltage electrical fields, may limit damage to tissues outside the myocardium.

Calibration. Primary—Secondary—Field
The Journal of the Acoustical Society of America, 1997The primary calibration of acoustic and vibration transducers are well standardized and confirmed by a round-robin inter-laboratory test. Secondary calibration is also very common with traceability to primary calibration. Examples of setups for microphone and accelerometer secondary calibration are discussed regarding accuracy, frequency response ...
