Panoramic Endocardial Optical Mapping Demonstrates Serial Rotors Acceleration and Increasing Complexity of Activity During Onset of Cholinergic Atrial Fibrillation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Activation during onset of atrial fibrillation is poorly understood. We aimed at developing a panoramic optical mapping system for the atria and test the hypothesis that sequential rotors underlie acceleration of atrial fibrillation during ...

Further genetic heterogeneity for autosomal dominant human sutural cataracts [PDF]

, 2003
A unique sutural cataract was observed in a 4-generation German family to be transmitted as an isolated autosomal, dominant trait. Since mutations in the gamma-crystallin encoding CRYG genes have previously been demonstrated to be the most frequent ...

Current limitations of cryogenic microwave oscillator frequency stability

, 2014
Technical paperCryogenic microwave oscillators built upon sapphire loaded cavity resonators exhibit excellent levels of frequency stability. Here we present an overview of the current understanding of the various processes and noise sources that limit ...
