Abstract Background The increasing use of intracardiac echocardiography (ICE) in the ablation of premature ventricular complexes (PVCs) has raised questions about its true efficacy and safety.Methods This retrospective study collected the periprocedural complications and PVC burden post ablation.The risk factors of PVC recurrence was further explor
Safety of drivers in freeway work zones has been a problem.Real-time crash prediction helps prevent crashes before they happen.This paper looks at real-time crash prediction in freeway work zones by using machine learning approaches.Both the Convolutional Neural Network and the Binary Logistic Regression model are introduced.For training and testin
Pervasive development across the country has resulted in unprecedented urbanization with a phenomenal change to the urban landscape.This rapid expansion of cities has generated characteristic local urban climates with an increased land surface temperature (LST) and the intensities of urban heat islands (UHI).The study on LST and UHI can be performe
