Retrograde recanalization demonstrated to be one of the most significant amendments of the technique and has recently become a vital complement to the classical antegrade approach in chronic total occlusion recanalization.Interventionists embark on this technique in complex lesions, in which the antegrade approach is not feasible Waste Receptacles
In order to improve the prediction accuracy of gas emission in the mining face, a method combining least absolute value convergence and selection operator (LASSO), whale optimization algorithm (WOA), and extreme gradient boosting (XGBoost) was proposed, along with the LASSO-WOA-XGBoost gas emission prediction model.Aiming at the monitoring data of
Food safety issues caused by pesticide residue have exerted far-reaching impacts on human daily life, yet the available detection methods normally focus on surface residue rather than pesticide penetration to the internal area of foods.Herein, we demonstrated gold nanoparticle (AuNP)-immersed paper imprinting mass spectrometry imaging (MSI) for mon
