Adequate sleep is essential for adolescents' cognitive function and academic performance. This study examines the relationship between sleep duration and academic outcomes among senior high school students. The data in this study were collected from 10th and 11th-grade students in international schools in Qingdao and Dalian. A one-sample z-test for...

In laser welding, the plasma plume often shields the input energy, causing laser beam defocusing and significantly impacting welding efficiency and quality. This paper elucidates experimental facts concerning the attenuation and dispersion of laser energy at varying ambient pressures, and derives the associated absorption and refraction mechanisms ...

Galaxy mergers are a crucial pathway for the growth and evolution of galaxies at the cosmic center. Supermassive black holes (SMBHs) are commonly present at the centers of galaxies. During galaxy mergers, the central SMBHs may form binary black hole systems and, in some cases, merge. Detecting and studying supermassive binary black hole systems wit...

As a commonly used symmetric encryption method, AES (Advanced Encryption Standard) still has some steps that cannot fully ensure the effectiveness of encryption, and Symmetric Key Encryption has the risk of key leakage in common. This paper mainly researches an optimization model of AES encryption method, which is based on the original AES encrypti...

Large-scale deep learning weather prediction models are revolutionizing the field of weather forecasting. GraphCast is the current state-of-the-art model, but its training is not explicitly designed for predicting extreme weather events. However, extreme weather prediction is more critical because it directly impacts public safety, potentially savi...
