Atrial fibrillation (AF) is regarded as a complex arrhythmia, with one or more co-existing
mechanisms, resulting in an intricate structure of atrial activations. Fractionated atrial …

为了剖析大地电磁信号和强干扰的本质特征, 进一步精细分离出微弱的大地电磁有用信号,
提出基于递归分析和聚类的大地电磁信噪辨识及分离方法. 首先, 运用递归分析法扩展大地电磁 …

Many physical situations involve chaotic systems implemented in hardware. Among them
one-dimensional piecewise linear maps are popular candidates for such applications …

In order to analyze the essential characteristics of magnetotelluric (MT) sounding data and
strong interferences, and further to separate weak useful MT signal, we propose a new …

Introduction The temporal behavior of atrial electrograms (AEGs) collected during persistent
atrial fibrillation (persAF) directly affects ablative treatment outcomes. We investigated …

Recently, several techniques have been presented for blind source separation using linear
or non-linear mixture models. The problem is to recover the original source signals without …

In this research a new way introduced for solving the underdetermined blind speech signal
separation problem when the number of observation is less than the sources for which the …

A fibrilação atrial é uma arritmia cardíaca caracterizada por ativações cardíacas turbulentas
e desorganizadas. O comportamento temporal de eletrogramas atriais (AEGs) coletados …

This work investigates an alternative approach to the problem of blind equalization. The
approach is based on complexity measures and is inspired by preceding successful …

In the present work, we sought to uncover possible deterministic dynamics in atrial tissue
activations during persistent atrial fibrillation (persAF) using recurrence plots (RP) and …
