In this study,a novel method is proposed for producing perovskite rare-earth manganese oxide magnetic refrigeration materials that exhibit superior properties compared to similar materials.The maximum magnetic entropy change values for this sample are 1.44 and 3.75 J·kg-1·K-1for magnetic fields of 2 and 7 T,respectively.Additionally,its relative cooling power has been calculated to be 101.96 and 404.78 J·kg-1,indicating good performance.Both results were obtained using the sample synthesized under a pressure of 4 GPa,and the sample has undergone a second phase transition.The critical behavior of the sample fits well with the mean field model.For different magnetic fields,there is a significant overlap between the values of the maximum magnetic entropy change and the temperature-averaged entropy change,indicating that the refrigeration performance of the sample after high pressure can approach its maximum capability.

Neuro- and Immuno-modulation Mediated by the Cardiac Sympathetic Nerve: A Novel Insight into the Anti-ischemic Efficacy of Acupuncture

引用

Journal of Traditional Chinese Medicine 2024年

作者： XI Hanqing LI Xia ZHANG Ziyi CUI xiang JING xianghong ZHU Bing gao Xinyan Institute of Acupuncture and Moxibustion China Academy of Chinese Medical Sciences

Communication between sympathetic nerves and the immune system is a crucial and active process during myocardial ischemia (MI)， as myocardial damage and inflammatory stimuli concurrently occur. Sympathetic nerves undergo structural and functional changes after MI， leading to adverse left ventricular (LV) remodeling and heart failure (HF). The complex inflammatory response to MI， including local myocardial anti-inflammatory repair and systemic immune reactions， plays a key role in adverse LV remodeling. Here， we review the progressive structural and electrophysiological remodeling of the LV and the involvement of sympathetic tone in complex and dynamic processes that are susceptible to MI pathological conditions. Acupuncture has been reported to effectively improve cardiac function， eliminate arrhythmia， and mitigate adverse LV remodeling via somatosensory regulation after MI. Moreover， acupuncture has an anti-inflammatory effect on the pathological process of myocardial ischemia. In this Review， we aim to summarize the involvement of sympathetic nerve activation in the neuro-immune modulation of structural and functional cardiac changes after MI. As a noninvasive method for sympathetic regulation， acupuncture is an ideal option because of its anti-ischemic efficacy. A better understanding of the neural circuitry that regulates cardiac function and immune responses following MI could reveal novel targets for acupuncture treatment.

World Journal of Hepatology 2024年第4期16卷 537-549页

作者： Jing-Jing Li Jia-Xi Mao Han-xiang Zhong Yuan-Yu Zhao Fei Teng Xin-Yi Lu Li-Ye Zhu Yang gao Hong Fu Wen-Yuan Guo Department of Liver Surgery and Organ Transplantation Shanghai Changzheng HospitalNaval Medical UniversityShanghai 200003China

The tumor microenvironment is a complex network of cells,extracellular matrix,and signaling molecules that plays a critical role in tumor progression and metastasis.Lymphatic and blood vessels are major routes for solid tumor metastasis and essential parts of tumor drainage conduits.However,recent studies have shown that lymphatic endothelial cells(LECs)and blood endothelial cells(BECs)also play multifaceted roles in the tumor microenvironment beyond their structural functions,particularly in hepatocellular carcinoma(HCC).This comprehensive review summarizes the diverse roles played by LECs and BECs in HCC,including their involvement in angiogenesis,immune modulation,lymphangiogenesis,and metastasis.By providing a detailed account of the complex interplay between LECs,BECs,and tumor cells,this review aims to shed light on future research directions regarding the immune regulatory function of LECs and potential therapeutic targets for HCC.

Development of a 2D spatial displacement estimation method for turbulence velocimetry of the gas puff imaging system on EAST

引用

Plasma Science and Technology 2024年第3期26卷 17-24页

作者：李乐天刘少承颜宁刘晓菊高翔 Anhui University Hefei 230039People's Republic of China Institute of Plasma Physics Chinese Academy of SciencesHefei 230031People's Republic of China

A gas puff imaging(GPI)diagnostic has been developed and operated on EAST since 2012,and the time-delay estimation(TDE)method is used to derive the propagation velocity of fluctuations from the two-dimensional GPI data.However,with the TDE method it is difficult to analyze the data with fast transient events,such as edge-localized mode(ELM).Consequently,a method called the spatial displacement estimation(SDE)algorithm is developed to estimate the turbulence velocity with high temporal resolution.Based on the SDE algorithm,we make some improvements,including an adaptive median filter and super-resolution technology.After the development of the algorithm,a straight-line movement and a curved-line movement are used to test the accuracy of the algorithm,and the calculated speed agrees well with preset speed.This SDE algorithm is applied to the EAST GPI data analysis,and the derived propagation velocity of turbulence is consistent with that from the TDE method,but with much higher temporal resolution.

We demonstrate a high-Q perfect light absorber based on all-dielectric doubly-resonant metasurface.Leveraging bound states in the continuum(BICs)protected by different symmetries,we manage to independently manipulate the Q factors of the two degenerate quasi-BICs through dual-symmetry perturbations,achieving precise matching of the radiative and nonradiative Q factors for degenerate critical coupling.We achieve a narrowband light absorption with a>600 Q factor and a>99%absorptance atλ_(0)=1550 nm on an asymmetric germanium metasurface with a 0.2λ_(0)thickness.Our work provides a new strategy for engineering multiresonant metasurfaces for narrowband light absorption and nonlinear applications.

Performance improvements in complementary metal oxide semiconductor devices and circuits based on fin field-effect transistors using 3-nm ferroelectric Hf0.5Zr0.5O2

Rare Metals 2024年第7期43卷 3242-3249页

作者： Zhao-Hao Zhang Yan-Na Luo gao-Bo Xu Jia-Xin Yao Zhen-Hua Wu Hong-Bin Zhao Qing-Zhu Zhang Hua-xiang Yin jun Luo Wen-Wu Wang Hai-Ling Tu Integrated Circuit Advanced R&D Center Institute of Microelectronics of Chinese Academy of Sciences School of Integrated Circuits University of Chinese Academy of Sciences State Key Laboratory of Advanced Materials for Smart Sensing General Research Institute for Nonferrous Metals

In this work,a conventional HfO2gate dielectric layer is replaced with a 3-nm ferroelectric（Fe） HZO layer in the gate stacks of advanced fin field-effect transistors（FinFETs）.Fe-induced characteristics,e.g.,negative drain induced barrier lowering（N-DIBL） and negative differential resistance（NDR）,are clearly observed for both p-and n-type HZO-based FinFETs.These characteristics are attributed to the enhanced ferroelectricity of the 3-nm hafnium zirconium oxide（HZO） film,caused by Al doping from the TiAlC capping layer.This mechanism is verified for capacitors with structures similar to the FinFETs.Owing to the enhanced ferroelectricity and N-DIBL phenomenon,the drain current(IDS)of the HZO-FinFETs is greater than that of HfO2-FinFETs and obtained at a lower operating voltage.Accordingly,circuits based on HZO-FinFET achieve higher performance than those based on HfO2-FinFET at a low voltage drain(VDD),which indicates the application feasibility of the HZO-FinFETs in the ultralow power integrated circuits.

Preliminary safety analysis for heavy water-moderated molten salt reactor

引用

Nuclear Science and Techniques 2024年第6期35卷 202-217页

作者： gao-Ang Wen Jian-Hui Wu Chun-Yan Zou xiang-Zhou Cai Jin-Gen Chen Man Bao College of Science University of Shanghai for Science and TechnologyShanghai 200093China Shanghai Institute of Applied Physics Chinese Academy of SciencesShanghai 201800China University of Chinese Academy of Sciences Beijing 100049China

The heavy water-moderated molten salt reactor(HWMSR)is a newly proposed reactor concept,in which heavy water is adopted as the moderator and molten salt dissolved with fissile and fertile elements is used as the fuel.Issues arising from graphite in traditional molten salt reactors,including the positive temperature coefficient and management of highly radio-active spent graphite waste,can be addressed using the HWMSR.Until now,research on the HWMSR has been centered on the core design and nuclear fuel cycle to explore the viability of the HWMSR and its advantages in fuel utilization.However,the core safety of the HWMSR has not been extensively studied.Therefore,we evaluate typical accidents in a small modular HWMSR,including fuel salt inlet temperature overcooling and overheating accidents,fuel salt inlet flow rate decrease,heavy water inlet temperature overcooling accidents,and heavy water inlet mass flow rate decrease accidents,based on a neutronics and thermal-hydraulics coupled code.The results demonstrated that the core maintained safety during the investigated accidents.
