Timely evaluation and reperfusion have improved the myocardial salvage and the subsequent recovery rate of the patients hospitalized with acute myocardial infarction (MI). Long waiting time and time-consuming procedures of in-hospital diagnostic testing severely affect the timeliness. We present a Poincare pattern ensemble-based method with the consideration of multi-correlated non-stationary stochastic system dynamics to localize the infarct-related artery (IRA) in acute MI by fully harnessing information from paper-based Electrocardiogram (ECG). The vectorcardiogram (VCG) diagnostic features extracted from only 2.5-s long paper ECG recordings were used to hierarchically localize the IRA—not mere localization of the infarcted cardiac tissues—in acute MI. Paper ECG records and angiograms of 106 acute MI patients collected at the Heart Artery and Vein Center at Fresno California and the 12-lead ECG signals from the Physionet PTB online database were employed to validate the proposed approach. We reported the overall accuracies of 97.41% for healthy control (HC) vs. MI, 89.41 ± 9.89 for left and right culprit arteries vs. others, 88.2 ± 11.6 for left main arteries vs. right-coronary-ascending (RCA) and 93.67 ± 4.89 for left-anterior-descending (LAD) vs. left-circumflex (LCX). The IRA localization from paper ECG can be used to timely triage the patients with acute coronary syndromes to the percutaneous coronary intervention facilities.

International audienceThis paper deals with a much less contemplated topic of carbon footprint (CFP) reduction in automated machining lines. A multi-objective problem for the simultaneous optimisation of line cost and carbon footprint while satisfying all the constraints of an automated production line with rotary transfer and turrets is presented. A framework for accounting and reduction of CFP and, hence, the energy consumption of the production line is put forward. This framework investigates the environmental impact of greenhouse gas emitted and energy consumed by the system-level processes during the machining and non-machining operations. Moreover, a binary scatter tabu search process for multi-objective optimisation (BSSPMO), a meta-heuristic based on scatter and tabu search procedure, is used for approximating the efficient frontier. To demonstrate the validation of the proposed approach, a case study is presented, and the numerical results are analysed. Though the trade-off between line cost and CFP is not a perfect Pareto, but it gives a very important conclusion about the trend of how these two critical parameters varies and the range in which it can be controlled
