Article Synopsis
  • The COVID-19 pandemic has created urgent public health challenges, highlighting the need for effective detection and diagnosis to save lives.
  • Traditional testing methods like RT-PCR are expensive and time-consuming, while manual X-ray analysis for COVID-19 diagnosis is labor-intensive.
  • This study introduces a computer-aided diagnosis system using chest X-ray images and a novel multiscale deep learning model, achieving high accuracy rates of up to 100% for classifying COVID-19 from X-rays, outperforming existing detection methods.

The elimination of ocular artifacts is critical in analyzing electroencephalography (EEG) data for various brain-computer interface (BCI) applications. Despite numerous promising solutions, electrooculography (EOG) recording or an eye-blink detection algorithm is required for the majority of artifact removal algorithms. This reliance can hinder the model's implementation in real-world applications.

The categorization of sleep stages helps to diagnose different sleep-related ailments. In this paper, an entropy-based information-theoretic approach is introduced for the automated categorization of sleep stages using multi-channel electroencephalogram (EEG) signals. This approach comprises of three stages.

The complex wavelet sub-band bi-spectrum (CWSB) features are proposed for detection and classification of myocardial infarction (MI), heart muscle disease (HMD) and bundle branch block (BBB) from 12-lead ECG. The dual tree CW transform of 12-lead ECG produces CW coefficients at different sub-bands. The higher-order CW analysis is used for evaluation of CWSB.

In this letter, the authors propose a new entropy measure for analysis of time series. This measure is termed as the state space correlation entropy (SSCE). The state space reconstruction is used to evaluate the embedding vectors of a time series.
