Shi-yi Wang, Zhiru Wang, Xinzhe Zhao
With the increasing development and popularity of smart wearable devices, smart bracelets have become one of the hottest smart devices today. Through a comparative analysis of existing products, this paper proposes improvement strategies in the three main directions of UI and module design, security, and handling of health issues to provide a product that is easier to use and meets the health needs of the elderly. For the direction of UI and module design, it is proposed to add the gesture recognition function and develop it in the direction of non-contact recognition based on the existing technology, and at the same time, use machine learning to achieve personalized recognition. Based on personalized module design, a GPS tracking device is installed to prevent users from being tracked, and a new network module is added to enable users to get in touch with others at a time when they encounter danger in remote areas. Improvement strategies in the security direction include data transmission, storage, and device security. The smart bracelet can use trusted computing for data encryption and storage by adding low-power core and optimizing the data transmission in three paths: local area network (LAN), public network (PN), and the cloud.Regarding health problem processing, it is proposed to achieve fall prevention through scene recognition and optimize the fall detection function through user information. In addition, this paper takes UV irradiation as an example to point out that smart bracelet devices can be added with new indicator detection technology to prevent some diseases. At the same time, a full voice interaction system can be developed to meet the social needs of the elderly.

Problems and Handling Methods of Laser Printers 激光打印机的问题和处理方法
Xiaoyue Guo
A laser printer is a common office and personal printing equipment widely welcomed for high-speed, high-quality print output. The high temperature usually causes the printer nozzle temperature to be too high, affecting the printing quality and even damaging the printer. This is because the laser printer works by attaching the toner to the paper through high-temperature sintering, hence the print head’s temperature. Maintaining a suitable temperature environment is crucial for the normal operation and life of the laser printer. In addition, If the position and thickness of the black and white tendons change, it may affect the uneven distribution of the ink when printing, resulting in patches or blur of the printed image. In the printer’s cartridges, the black and white bars are separated, ensuring that the ink in the cartridge is evenly distributed when printing. If the position and thickness of the black and white tendons change, it may affect the uneven distribution of the ink when printing, resulting in patches or blur of the printed image. Therefore, when replacing ink cartridges or resetting or modifying some settings of the printer, be careful to be sure not to damage the printer. This study aims to solve the technical defects of laser printers, improve the level of printing technology, and improve the user experience.
激光打印机是一种常见的办公和个人打印设备,因其高速、高质量的打印输出而广受欢迎。高温通常会导致打印机喷嘴温度过高,影响打印质量,甚至损坏打印机。这是因为激光打印机的工作原理是通过高温烧结将墨粉附着在纸张上,因此打印头的温度较高。保持适宜的温度环境对激光打印机的正常运行和使用寿命至关重要。此外,如果黑白筋的位置和粗细发生变化,可能会影响打印时墨水的不均匀分布,导致打印图像出现斑块或模糊。在打印机的墨盒中,黑白筋是分开的,可以确保打印时墨盒中的墨水分布均匀。如果黑白筋的位置和粗细发生变化,可能会影响打印时墨水的均匀分布,导致打印图像出现斑块或模糊。因此,在更换墨盒或重置、修改打印机的某些设置时,一定要注意不要损坏打印机。本研究旨在解决激光打印机的技术缺陷,提高打印技术水平,改善用户体验。

Guanqi Niu
With the continuous progress of science and technology, all kinds of electrical and electronic equipment are applied to production and life. However, bad electromagnetic interference will affect the normal operation of the equipment and reduce work efficiency. This paper analyzes the situation and source of electromagnetic interference in the industrial field and introduces several common anti-interference methods. And take corresponding measures according to different types of interference. This paper introduces electromagnetic shielding, filtering, and other technologies, and the application scenarios of various anti-interference methods are analyzed. When the working environment and the nature of interference emission change, the anti-interference strategy should be adjusted accordingly. Implementing these measures will significantly improve the electromagnetic compatibility of the system, reduce the electromagnetic interference phenomenon in the industrial site, and ensure the stable and efficient work of the system. Although electromagnetic interference cannot be eliminated, summarizing and analyzing existing technologies helps to develop new technologies and provides more possibilities for anti-interference.

Rice is a major food crop and one of the most cadmium absorbing and bulk cereal crops. OsCTF, a gene involved in the efflux of heavy metal Cd in rice, which is closely related to the amount of Cd accumulation in rice. In this study, CRISPR-dCas9 technology was used to regulation of OsCTF 3 ‘- UTR demethylation in rice to improve the amount of OsCTF gene expression, which was detected by direct detection, using a Chop-PCR method to detect the methylation level in rice, and real-time quantitative PCR to detect the level of OsCTF gene expression; at the same time,cadmium stress was detected, DNA methylation was analyzed by sulfite sequencing and McrBC-PCR, and OsCTF gene expression was detected by differential expression gene analysis. OsCTF expression and cadmium accumulation in rice after demethylation of the OsCTF 3 ‘- UTR were measured by both direct and cadmium stress assays. Then, OsCTF 3 ‘-UTR demethylation level, OsCTF gene expression and cadmium accumulation in offspring were measured by self-cross method of transgenic rice. Finally, a new rice line with low cadmium accumulation was formed.

Hanze Wan
With the rapid development of advanced technologies like the mobile internet, cloud computing, and the Internet of Things, the era of big data is gradually upon us. In this era, big data has been widely utilized in various fields like business, finance, social networking, and healthcare, and the value of data has become increasingly prominent. Data has become a new factor of production, the digital economy has become a new engine of development, and an important driving force for promoting social progress and economic development. However, with the advancement of big data technology, the risks of data leakage and misuse have increased. Personal data information leakage or misuse can lead to personal privacy infringement and fraud, such as the Sina Weibo data leak in March 2020 where attackers breached part of the Sina Weibo database, obtaining sensitive data including real names, website usernames, genders, locations, and phone numbers, impacting 538 million Weibo users. Therefore, there is an increasing demand for data information privacy protection. This paper will explore the core technologies and application scenarios in data information privacy protection and investigate data privacy protection in real-life settings.

Tianyi Xu
In recent years, with the development of the semiconductor industry, Moore’s Law has gradually become ineff ective, making it increasingly diffi  cult for people to improve chip manufacturing processes. Many people believe that Moore’s Law will no longer exist. However, with Samsung announcing the production of 3-nanometer gate-all-around (GAA) architecture process technology chips on June 30, 2022, the chip process has been further advanced. Moore’s Law is expected to continue in the coming years. This article will mainly introduce why GAAFET will become the mainstream fi eld-eff ect transistor in the future. The potential problems that GAAFET may encounter in its future development will also be analyzed, including massive research and development costs and a longer research and development cycle.

Ant colony algorithm based fuzzy PID control of unmanned aerial vehicle under wind disturbance conditions 风干扰条件下基于蚁群算法的无人飞行器模糊 PID 控制
Xichen Tang
A drone is an unmanned aerial vehicle that has been widely used in military, civil and commercial fields. UAVs need to maintain a smooth and stable flight state during flight to accomplish various tasks, such as reconnaissance, scouting, aerial photography, transportation, and so on. In this paper, both the ant colony algorithm and fuzzy PID control are utilized to investigate the control of quadrotor UAVs under wind disturbance conditions. The optimization of the fuzzy PID control algorithm is conducted through the application of a convolutional neural network under wind disturbance conditions.The system construction and simulation test are conducted using MATLAB and Simulink. The experimental results are analyzed, experimental conclusions are drawn, and the results are compared with those obtained using the traditional PID control algorithm and fuzzy PID control algorithm. This comparison helps demonstrate the extent of optimization achieved by the convolutional neural network on the fuzzy PID control algorithm.The results obtained from comparing the performance with the traditional PID control algorithm and fuzzy PID control algorithm demonstrate the degree of optimization achieved by applying the convolutional neural network to the fuzzy PID control algorithm. The findings indicate that the fuzzy PID control, optimized by the ant colony algorithm, can effectively be utilized for controlling quadrotor UAVs under wind disturbance conditions.

Jiajun Han
The strategic board game Gomoku has become a compelling domain for artificial intelligence (AI) research, particularly in developing and applying machine learning techniques. This paper comprehensively analyzes advanced machine learning strategies in Gomoku, focusing on logistic regression for board evaluation, neural networks for pattern recognition, and reinforcement learning for strategic gameplay. We discuss integrating these techniques in creating a sophisticated AI capable of high-level play and adaptability. Through this exploration, we highlight the potential of AI in strategic decision-making and its broader applications beyond board games.
