A type of two-degree-of-freedom vibration system with bilateral nonlinear constraints is established.Through the fourth-order Runge-Kutta numerical algorithm, the dynamic characteristics of the p/1 periodic motion of the system under low frequency excitation, the law of mutual transition and the corresponding law of the coexistence zone Athletic Pa
Abstract Over the last couple of decades, community question‐answering sites (CQAs) have been a topic of much academic interest.Scholars have often leveraged traditional machine learning (ML) and deep learning (DL) to explore the ever‐growing volume of content that CQAs engender.To clarify the current state of the CQA literature that has used M
Decarbonization policies are being implemented in all EU countries where renewable energy is being developed.One of the main energy sources used for this purpose is photovoltaic energy.However, the development of photovoltaics does not only mean environmental Wheels benefits in the form of green energy and thus a reduction in greenhouse gas emissio
Abstract Objectives Arachnids have fascinating and unique biology, particularly for questions on sex Accessories differences and behavior, creating the potential for development of powerful emerging models in this group.Recent advances in genomic techniques have paved the way for a significant increase in the breadth of genomic studies in non-model
