1Optimal operation of electricity, natural gas and heat systems considering integrated demand responses and diversified storage devices显示文摘In recent years, the increasing penetration level of renewable generation and combined heat and power(CHP) technology in power systems is leading to significant changes in energy production and consumption patterns. As a result, the integrated planning and optimal operation of a multi-carrier energy(MCE) system have aroused widespread concern for reasonable utilization of multiple energy resources and efficient accommodation of renewable energy sources. In this context, an integrated demand response(IDR) scheme is designed to coordinate the operation of power to gas(P2 G) devices, heat pumps,diversified storage devices and flexible loads within an extended modeling framework of energy hubs. Subsequently, the optimal dispatch of interconnected electricity,natural gas and heat systems is implemented considering the interactions among multiple energy carriers by utilizing the bi-level optimization method. Finally, the proposed method is demonstrated with a 4-bus multi-energy systemand a larger test case comprised of a revised IEEE 118-bus power system and a 20-bus Belgian natural gas system.Linna NI Weijia LIU Fushuan WEN Yusheng XUE Zhaoyang DONG Yu ZHENG Rui ZHANG 2018Journal of Modern Power Systems and Clean Energy2018,6,3:30
2Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems.SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui 2012Science China Earth Sciences2012,55,7:24
3The effect of environmental factors on spatial variability in land use change in the high-sediment region of China's Loess Plateau显示文摘In areas with topographic heterogeneity, land use change is spatially variable and influenced by climate, soil properties, and topography. To better understand this variability in the high-sediment region of the Loess Plateau in which soil loss is most severe and sediment diameter is larger than in other regions of the plateau, this study builds some indicators to identify the characteristics of land use change and then analyze the spatial variability as it is affected by climate, soil property, and topography. We build two indicators, a land use change intensity index and a vegetation change index, to characterize the intensity of land use change, and the degree of vegetation restoration, respectively. Based on a subsection mean method, the two indicators are then used to assess the spatial variability of land use change affected by climatic, edaphic, and topographic elements. The results indicate that: 1) Land use changed significantly in the period 1998–2010. The total area experiencing land use change was 42,302 km2, accounting for 22.57%of the study area. High-coverage grassland, other woodland, and forest increased significantly, while low-coverage grassland and farmland decreased in 2010 compared with 1998. 2) Land use change occurred primarily west of the Yellow River, between 35 and 38 degrees north latitude. The four transformation types, including(a) low-coverage grassland to medium-coverage grassland,(b) medium-coverage grassland to high-coverage grassland,(c) farmland to other woodland, and(d) farmland to medium-coverage grassland, were the primary types of land use change, together constituting 60% of the area experiencing land use change. 3) The spatial variability of land use change was significantly affected by properties of dryness/wetness, soil conditions and slope gradient. In general, land use changed dramatically in semi-arid regions, remained relativelystable in arid regions, changed significantly in clay-rich soil, remained relatively stable in clay-poor soil, changed dramatically in steeper slopes, and remained relatively stable in tablelands and low-lying regions. The increase in vegetation coincided with increasing changes in land use for each physical element. These findings allow for an evaluation of the effect of the Grain to Green Program, and are applicable to the design of soil and water conservation projects on the Loess Plateau of China.LUO Ya YANG Shengtian ZHAO Changsen LIU Xiaoyan LIU Changming WU Linna ZHAQ Haigen ZHANG Yichi 2014Journal of Geographical Sciences2014,24,5:5

5Request Merging Based Cross-User Deduplication for Cloud Storage with Resistance Against Appending Chunks Attack显示文摘Cross-user deduplication is an emerging technique to eliminate redundant uploading in cloud storage.Its deterministic response indicating the existence of data creates a side channel to attackers,which makes the privacy in the cloud at risk.Such kind of attack as well as further appending chunks attack,still cannot be well resisted in current solutions,thus is becoming a big obstacle in using this technique.We propose a secure cross-user deduplication,called Request merging based deduplication scheme(RMDS),which takes the lead to consider resistance against appending chunks attack in a lightweight way,let alone side channel attack.We utilize the proposed XOR based chunk-level server-side storage structure together with a request merging strategy to obfuscate attackers in minimized communication overhead.The experiment results show that,with security guaranteed,the proposed scheme is more efficient comparing with the state of the art.TANG Xin ZHANG Yi ZHOU Linna LIU Dan HU Bingwei 2021Chinese Journal of Electronics2021,30,2:3

15Adaptive Optimal Output Regulation of Interconnected Singularly Perturbed Systems With Application to Power Systems显示文摘This article studies the adaptive optimal output regulation problem for a class of interconnected singularly perturbed systems(SPSs) with unknown dynamics based on reinforcement learning(RL).Taking into account the slow and fast characteristics among system states,the interconnected SPS is decomposed into the slow time-scale dynamics and the fast timescale dynamics through singular perturbation theory.For the fast time-scale dynamics with interconnections,we devise a decentralized optimal control strategy by selecting appropriate weight matrices in the cost function.For the slow time-scale dynamics with unknown system parameters,an off-policy RL algorithm with convergence guarantee is given to learn the optimal control strategy in terms of measurement data.By combining the slow and fast controllers,we establish the composite decentralized adaptive optimal output regulator,and rigorously analyze the stability and optimality of the closed-loop system.The proposed decomposition design not only bypasses the numerical stiffness but also alleviates the high-dimensionality.The efficacy of the proposed methodology is validated by a load-frequency control application of a two-area power system.Jianguo Zhao Chunyu Yang Weinan Gao Linna Zhou Xiaomin Liu 2024IEEE/CAA Journal of Automatica Sinica2024,11,3:0
16Electrochemical synthesis of dipyrazolo/dipyrimidine-fused pyridines via oxidative domino cyclization of C(sp^(3))–H bonds显示文摘An electrochemically oxidative domino cyclization reaction of methyl azaarenes/ketones with pyrazol-5-amines and 6-amino-pyrimidine-2,4-diones was developed, providing a variety of dipyrazolo[3,4-b:4’,3’-e]pyridines and dipyrimidine-fused pyridines with moderate to good yields. The reaction involved two C–C bond formations and one C–N bond formation in one pot. Moreover, the photoluminescence properties of the representative dipyrazolo[3,4-b:4’,3’-e]pyridines were investigated.Peng Qian Linna Xu Wenyan Wang Lin Zhang Liang Tang Jiaojiao Liu Liangquan Sheng 2022Organic Chemistry Frontiers2022,9,6:0
17Pure Red Cell Aplasia Caused by Parvovirus B19 in Patients with Human Immunodeficiency Virus Infection: A Series of Four Cases显示文摘Parvovirus B19(B19V)infection can cause pure red cell aplasia(PRCA)in patients with human immunodeficiency virus(HIV)infection.Intravenous immunoglobulin(IVIG)is a preferred treatment option.From July 2019 to March 2022,four patients with HIV infection were admitted to Guangzhou Eighth People’s Hospital with dizziness and fatigue and were diagnosed with PRCA.Blood investigations revealed severe anemia and the B19V genome.Therefore,the four patients were diagnosed with B19V-induced PRCA.All four patients received red blood cell transfusion in the setting of antiretroviral therapy,and two of the four patients received intravenous immunoglobulin(IVIG).After 3-7 months of treatment,all four patients recovered,although two did not receive IVIG.This suggests that IVIG is not always necessary for the treatment of PRCA in patients with HIV infection and that effective antiretroviral therapy and immunological reconstitution play an important role in the eradication of parvovirus.Feilong Xu Yulong Wang Linjin Fan Yaozu He Xiejie Chen Pengfei Ye Linna Liu Jun Qian Linghua Li 2023Infectious Diseases & Immunity2023,3,3:0
18Functions of ULK1 in autophagy and non-autophagy pathways and its implications in human physiology and disease显示文摘ULK1(unc-51 like autophagy activating kinase 1),a mammalian serine/threonine kinase,is a key component of autophagy initiation complex and helps to induce all types of autophagy.Canonical autophagy is a process in which,through the interactions of a series of autophagy-related proteins,damaged organelles or misfolded proteins are engulfed by autophagosomes and then merged with lysosomes to be degraded.Thus,canonical autophagy is an important constituent part of the cellular“quality control.”Besides,accumulating evidence indicates that ULK1 exerts autophagy-independent effects in a cell-specific manner.For example,ULK1 facilitates neurite elongation through the regulation of endoplasmic reticulum(ER)–Golgi trafficking in neurons,stimulates phosphopentose pathway to help NADPH(nicotinamide adenine dinucleotide phosphate hydrogen)production,and acts as a duplex regulator in type I IFN(type I interferon)induced innate immune response.Considering the importance and diversity of ULK1 in various biological processes,this review aims to present a comprehensive overview of autophagy and non-autophagy related functions of ULK1 in a variety of human physiological,pathological,and disease processes.LINNA TAN YUYONG TAN DELIANG LIU 2020BIOCELL2020,44,4:0
19Research on multi-color OLED with bi-directional charge transfer using Ag:Mg as intermediate electrode显示文摘Organic light-emitting devices(OLEDs) have received widespread attention due to their excellent luminescence performance and flexibility.In this work,we demonstrate a novel two-color OLED,in which the forward and reverse units are vertically stacked together using Ag:Mg as an intermediate electrode for charge injection and transfer.Due to the extremely thin Ag:Mg film layer has a relatively smooth surface,it plays a critical role in the reverse unit light emission of the device.Thus,it is realized that the device emits green and red light when forward and reverse voltages are applied respectively.This provides a new possibility for future OLEDs lighting and display developments.The OLEDs were prepared by using such Ag:Mg intermediate electrodes,and a maximum brightness of 451.14 cd/m^(2) and an external quantum efficiency(EQE) of 3.82% were obtained at a small current density.LIU Linna GAO Xiongwei WAN Chunchen ZHANG Fanghui 2023Optoelectronics Letters2023,19,6:0
20Inhibition of lysine-specific demethylase 1(LSD1)prevented tumor growth and metastasis by downregulating PD-L1 expression in lung adenocarcinoma显示文摘Lysine-specific demethylase 1(LSD1),as a histone lysine demethylase,demethylates monomethyl and dimethyl of histone H3 on lysine 4(H3K4)and lysine 9(H3K9).Studies have reported that high LSD1 expression promotes cell proliferation,migration,and invasion by regulating chromatin morphology and gene expression,and is closely related to the development of non-small cell lung cancer(NSCLC).1 However,the underlying mechanism of LSD1 on cell proliferation and migration remains unclear.Pengxing He Linna Du Pan Hao Han Yang Yufei Ren Huiqin Kang Yanli Ding Wen Zhao Yichao Xu Hongmin Liu 2023Genes & Diseases2023,10,5:0
