Realizing Constant Current and Constant Voltage Outputs and Input Zero Phase Angle of Wireless Power Transfer Systems with Minimum Component Counts
600 IEEE TRANSACTIONS ON INTELLIGENT TRANSPORTATION SYSTEMS, VOL. 22, NO. 1, JANUARY 2021 Realizing Constant Current and Constant Voltage Outputs and Input Zero Phase Angle of Wireless Power Transfer Systems With Minimum Component Counts Jianghua Lu , Student Member, IEEE, Guorong Zhu , Senior Member, IEEE,DeyanLin,Member, IEEE, Yiming Zhang , Member, IEEE, Haoran Wang , Member, IEEE, and Chunting Chris Mi , Fellow, IEEE Abstract— In both normal and fast wireless electric vehicle advantages of its high specific energy, energy density, and high charging systems, constant current/constant voltage (CC/CV) cycle lifetime. The wireless power transfer (WPT) technology charging profile, regardless of the variation of the battery [1], [2] using magnetic or electric field coupling, namely the state of charge, is one of the most essential characteristics to ensure the battery performance and reliability. The input zero inductive power transfer (IPT) or capacitive power transfer phase angle (ZPA) is able to minimize the system volt-ampere (CPT), provides a promising solution for both normal and fast rating, enhance the power transfer capability, and make it charging [3], [4] of EV Li-ion batteries. Over the full range easy to achieve soft-switching operation over the full range of of the Li-on battery charge, the battery pack equivalent load battery charging profile. Therefore, the load-independent CC and resistance, which defined as the ratio of the charging voltage CV output characteristics with ZPA conditions are necessary for wireless charging systems. However, the existing methods to the charging current, may be roughly from a few ohms to that can achieve these functions either add power switches or several hundred ohms [5]. -

However, few STEM programs have been designed based Ya-Jun Wang on cultural-historical events. To explore this issue, the present study drew on the cultural-historical activity theory and the content analysis method by adopting the descriptive-interpretative approach to explore the STEM content of the Dujiang- Introduction yan Irrigation System (DIS) in present-day Sichuan, China. As early as 2,275 years ago Science, Technology, Engineering and Mathematics (STEM) education is during the Warring States period, Li Bing, recognized as the world’s top educational project (Sergis et al., 2019).

The al., 2018). In recent years, STEM has been widely advocated and implemented results of this study indicate that the DIS in education because it is considered to have a great impact on students’ incorporates Science (e.g., the hydraulic interdisciplinary learning, which can be seen as an important driving force principle), Technology (e.g., making a large for the progress of a country (Kuo et al., 2019).

Ethanol Affects Behavior and HPA Axis Activity During Development In
www.nature.com/scientificreports OPEN Ethanol afects behavior and HPA axis activity during development in zebrafsh larvae Wenxiao Du1*, Xiaoli Chen2, Min Shi1, Fuhua Bian1 & Zhenjun Zhao1* Recent studies have shown that long-term alcohol intake from food can lead to numerous mental disorders in humans, and the social and health efects of excessive intake of alcohol currently represent serious problems for governments and families worldwide. However, to date, it has not been determined how alcohol afects the hypothalamic–pituitary–adrenal (HPA) axis. The zebrafsh ofers a good model for studying the toxicology of food-grade ethanol. In the present study, using zebrafsh larvae exposed to 1% ethanol, we performed zebrafsh behavioral analysis. Samples were collected for enzyme-linked immunosorbent assay (ELISA) and quantitative real time-polymerase chain reaction (qRT-PCR) experiments, and statistical analysis was performed. We found that ethanol decreased the locomotor activity of zebrafsh larvae, which showed a more intense reaction to external stimuli. Ethanol also increased the level of HPA axis hormones in zebrafsh larvae, infuenced the level of neurotransmitters, and altered the expression of key genes in neurotransmitter metabolism. Ethanol exposure afects zebrafsh behavior, increases the level of HPA axis hormones in zebrafsh larvae, afects the level of neurotransmitters, and afects the expression of key genes in dopamine and serotonin metabolism. These fndings may help to elucidate the efects of ethanol on HPA axis activity. Ethanol is a substance consumed daily by humans that can cause considerable harm to human health, especially in minors1. Indeed, the social and health efects of alcoholism are among the most serious problems faced by governments and families every year 2. -
