Time irreversibility, which characterizes nonequilibrium processes, can be measured based on the probabilistic differences between symmetric vectors. To simplify the quantification of time irreversibility, symmetric p...

Electrocardiogram (ECG) has emerged as a widely accepted diagnostic instrument for cardiovascular diseases (CVD). The standard clinical 12-lead ECG configuration causes considerable inconvenience and discomfort, while wearable devices offers a more practical alternative. To reduce information gap between 12-lead ECG and single-lead ECG, this study proposes a multi-channel masked autoencoder (MCMA) for reconstructing 12-Lead ECG from arbitrary single-lead ECG, and a comprehensive evaluation benchmark, ECGGenEval, encompass the signal-level, feature-level, and diagnostic-level evaluations. MCMA can achieve the state-of-the-art performance. In the signal-level evaluation, the mean square errors of 0.0175 and 0.0654, Pearson correlation coefficients of 0.7772 and 0.7287. In the feature-level evaluation, the average standard deviation of the mean heart rate across the generated 12-lead ECG is 1.0481, the coefficient of variation is 1.58%, and the range is 3.2874. In the diagnostic-level evaluation, the average F1-score with two generated 12-lead ECG from different single-lead ECG are 0.8233 and 0.8410.

This invited Team Profile was created by the scientists in the Highly Operational Team (HOT) led by the Shustova group from the university of South Carolina (USA). HOT researchers are located at four universities ( the university of South Carolina , Clemson university , the university of Florida , and Chulalongkorn university) and one national laboratory ( Savannah River National laboratory ) from two different countries, USA and Thailand. The team recently published an article using the synergy among the HOT participants to reveal the synthetic pathways toward preparation of transuranic heterometallic extended metal–organic materials, providing mechanistic details for their formation, and establishing a structure–property relationship: “f-block MOFs: A Pathway to Heterometallic Transuranics” , K.
