Simulation-based deep learning for lightning localization using convolutional autoencoder and multilayer perceptron

Lightning-induced overvoltages are a major cause of faults and outages in overhead transmission systems, significantly affecting the reliability and operational continuity of power networks. Accurate and timely localization of lightning strikes is therefore essential for improvin...

Direct loading of cylindrical WST specimens for Mode I rock fracture energy evaluation: a proof-of-concept study

This study presents a proof-of-concept assessment of an alternative loading configuration for evaluating Mode I rock fracture energy using cylindrical Wedge Splitting Test (WST) specimens subjected to direct tensile opening at the specimen groove. The system uses a simple shear-t...

An interpretable SCA-ANN framework for WTI crude oil price forecasting

Abstract The recent conflict in the Strait of Hormuz as a critical oil transmit checkpoint combined with the market's inherent instability and the complex, nonlinear interactions among key influencing factors, makes accurate crude oil price forecasting a formidable challenge. Con...

Examination of the thermodynamic behavior of binary mixtures of 2-hydroxyethylammonium acetate (2-HEAA) with 1-propanol, 3-amino-1-propanol, 1-amino-2-propanol, and ethanolamine

The thermodynamics of mixtures was investigated, focusing on the protic ionic liquid 2-hydroxyethylammonium acetate ([2-HEAA]) in combination with 1-propanol ([1-Pr]), 3-amino-1-propanol ([AP]), 1-amino-2-propanol ([MIPA]), and ethanolamine ([EA]). Density ( ρ ), speed of sound (...

Psychological risk factors for non-suicidal self-injury in sexually traumatized adolescents: a cross-sectional analysis with random forest classification

Non-suicidal self-injury (NSSI) is a significant mental health issue among adolescents, especially those with histories of sexual trauma. This study examined the individual and synergistic roles of posttraumatic stress symptoms (PTSS), depression, anxiety, and sleep quality in pr...

Behavioral and neural effects of right temporoparietal junction itbs during empathy processing in women

The right temporoparietal junction (rTPJ) is one neural region that has been implicated in empathy in previous studies. However, prior findings regarding its role have been inconsistent. Moreover, methodological limitations in earlier research, including the use of suboptimal emp...
