Abstract.Promoting the whole-county (city or district) construction of rooftop distributed photovoltaic generation is an important part in realizing the two major national strategies of "carbon peak, carbon neutrality" and rural revitalization. In this paper, a distributed photovoltaic generation system design scheme based on substituting 50 kW inverter for 100 kW inverter is proposed for industrial and commercial rooftop photovoltaic projects. Through detailed comparative analysis, it is concluded that the design scheme entailing the use of 50 kW inverters is more economic and cost-effective than … Read more →

Abstract.In the field of ocean engineering, the efficiency and safety of ship operation are significantly affected by waves. Faced with the instability and safety risks of ship crane operation under complex sea conditions, a design and research method of efficient wave compensation device based on Stewart platform is proposed in this paper, aiming at developing a compensation system that can respond in real time and effectively counteract the effects of waves, so as to improve the safety and efficiency of offshore operations. Aiming at the limitation of traditional wave compensation technology, this … Read more →

Abstract.Objective: To investigate the effects of black rice anthocyanins extract (BSE) on depression-like behavior in mice with chronic unpredictable mild stress (CUMS). Methods: A total of 30 male Kunming mice were randomly divided into Control group, model group (CUMS) and black rice anthocyanin extract group (300 mg/kg). Except the blank group, all mice were treated with CUMS to induce depression. After 21 days of intragastric administration, the behavioral changes of the mice were analyzed by body weight, sucrose preference test, open field test, and water maze test. Enzyme-linked immunosorbent … Read more →

Abstract.In pace with the development of the economy, the spiritual entertainment brought by movies is increasingly valued by people, and the problem of how to recommend the most suitable movie for users among the numerous movies also arises. Based on this, experiments were conducted using convolutional neural networks in the field of deep learning for movie recommendation. The convolutional neural network was trained using user information, movie information, and user movie rating data from the Douban Movie Network. In data preprocessing, instead of converting category fields to one hot encoding, they … Read more →
