Regularization Techniques for ECG Imaging during Atrial Fibrillation: a Computational Study

Frontiers in Physiology, 2016
The inverse problem of electrocardiography is usually analyzed during stationary rhythms. However, the performance of the regularization methods under fibrillatory conditions has not been fully studied.

Study on Impact–Echo Response of Concrete Column near the Edge

Applied Sciences, 2023
The impact–echo method is a superior method for detecting the health of concrete structures, but it has the disadvantage of significant errors when identifying structural boundaries. In order to overcome this limitation, this paper proposes a calculation

High spatial frequencies dominate perception [PDF]

Bulletin of the Psychonomic Society, 1975
An effect is described which suggests that very high spatial frequencies may “mask” low spatial frequencies. The effect cannot be interpreted in terms of “critical band masking” and is probably due to the higher spatial frequencies dominating our attention.

Relationship Between Electrical Instability and Pumping Performance During Ventricular Tachyarrhythmia: Computational Study

Frontiers in Physiology, 2020
There are representative electrical parameters for understanding the mechanism of reentrant waves in studies on tachyarrhythmia, namely the action potential duration (APD), dominant frequency, phase singularity, and filament.

Selection in a Subdivided Population With Dominance or Local Frequency Dependence [PDF]

Genetics, 2003
Abstract The interplay between population structure and natural selection is an area of great interest. It is known that certain types of population subdivision do not alter fixation probabilities of selected alleles under genic, frequency-independent selection.
