| 1 | Optimal 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 | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 30 |

| 3 | Circumjacent distribution pattern of the Lungmachian graptolitic black shale(early Silurian) on the Yichang Uplift and its peripheral region显示文摘Stratigraphic hiatuses of variable time intervals within the Rhuddanian to early Aeronian(Llandovery, Silurian) are identified in the area bordering East Chongqing, West Hubei and Northwest Hunan in central China. Their distribution suggested the existence of a local uplift, traditionally named the Yichang Uplift. The diachronous nature of the basal black shale of the Lungmachi Formation crossing different belts of this Uplift signifies the various developing stages during the uplifting process.The present paper defines the temporal and spatial distribution pattern of the Yichang Uplift, which might be one of the important controlling factors for the preservation and distribution of the shale gas in this region, as it has been demonstrated that the shale gas exploration is generally less promising in the areas where more of the basal part of the Lungmachi Formation is missing.Therefore, better understanding of the circumjacent distribution pattern developed throughout the uplifting process may provide the important guidance for the shale gas exploration. The present work is a sister study to the published paper, 'Stage-progressive distribution pattern of the Lungmachian black graplolitic shales from Guizhou to Chongqing, Central China'. These two studies thus provide a complete Ordovician-Silurian black shale distribution pattern in the Middle and Upper Yangtze, a region with the major shale gas fields in China. | Xu CHEN Qing CHEN Yongyi ZHEN Hongyan WANG Linna ZHANG Junpeng ZHANG Wenhui WANG Zhaohui XIAO | 2018 | Science China Earth Sciences2018，61，9： | 9 |
| 4 | Paleogeographic evolution of the Lower Yangtze region and the break of the “platform-slope-basin” pattern during the Late Ordovician显示文摘Wide distribution of the black shales and diversification of the graptolite fauna in South China during the Late Ordovician resulted from its unique paleogeographic pattern, which was significantly affected by the paleogeographic evolution of the Lower Yangtze region. In the study, 120 Upper Ordovician sections from the Lower Yangtze region were collected, and a unified biostratigraphic framework has been applied to these sections to establish a reliable stratigraphic subdivision and correlation. Under the unified time framework, we delineate the distribution area of each lithostratigraphic unit, outline the boundary between the sea and land, and reconstruct the paleogeographic pattern for each graptolite zone. The result indicates that, with the uplift and expansion of the ‘Jiangnan Oldland' in the beginning of the late Katian, the oldland extended into the Yangtze Sea gradually from south to north, which finally separate the Jiangnan Slope and the Yangtze Platform. Consequently,the longstanding paleogeographic pattern of 'platform-slope-basin' in South China was broken. The paleogeographic change led to sedimentary differentiation among the two sides of the ‘Jiangnan Oldland' during the Late Ordovician. This event also led to the closure of the eastern exit of the Upper Yangtze Sea, and formed a semi-closed, limited and stagnant environment for the development of the organic-rich black shales during the Late Ordovician. The major controlling factors of these paleogeographic changes in the Lower Yangtze region were not consistent from the Katian to the Hirnantian. In the late Katian, the sedimentary differentiation between the east and west sides mostly resulted from regional tectonic movement-the Kwangsian Orogeny.However, during the Hirnantian, the whole Yangtze region became shallower, which was mostly influenced by the concentration of the Gondwana ice sheet and the consequent global sea level drop. | Qing CHEN Junxuan FAN Linna ZHANG Xu CHEN | 2018 | Science China Earth Sciences2018，61，5： | 5 |
| 5 | The 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 | 2014 | Journal of Geographical Sciences2014，24，5： | 5 |
| 6 | Request 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 | 2021 | Chinese Journal of Electronics2021，30，2： | 3 |
| 7 | Assessment and analysis of microwave emissivity and transmissivity of a deciduous forest towards the estimate of vegetation biomass显示文摘Forests play an important role in the global carbon cycle and have a potential impact on global climatic change.Monitoring forest biomass is of considerable importance in understanding the hydrological cycle.Because of the problem of dense forest cover,no reliable method with which to retrieve soil moisture in forest areas from the microwave emission signature has been established.All of these issues relate to the microwave emissivity and transmissivity characteristics of a forest.The microwave emission contribution received by a sensor above a forest canopy comes from both the soil surface and the vegetation layer.To analyze the relationship of forest biomass and forest emission and transmissivity,a high-order emission model,the matrix-doubling model,which consists of both soil and vegetation models,was developed and then validated for a young deciduous forest stand in a field experiment.To simulate the emissivity and transmissivity of a deciduous forest in the L and X bands using the matrix-doubling model,the parameters of components of deciduous trees when the leaf area index varies from 1 to10 were generated by an L-system and a forest growth model.The emissivity and transmissivity of a forest and the relationships of these parameters to forest biomass are presented and analyzed in this paper.Emissivity in the L band when the leaf area index is less than 6 and at viewing angles less than 40°,and transmissivity in the L band are the most sensitive parameters in deciduous forest biomass estimation. | ZHANG ZhongJun YU XianChuan ZHAO ShaoJie CHAI LinNa | 2014 | Science China Earth Sciences2014，57，3： | 2 |

| 9 | Intestinal dysbiosis exacerbates the pathogenesis of psoriasis-like phenotype through changes in fatty acid metabolism显示文摘The intestinal microbiota has been associated with host immunity as well as psoriasis;however,the mechanism of intestinal microbiota regulating psoriasis needs to be demonstrated systematically.Here,we sought to examine its role and mechanism of action in the pathogenesis of psoriasis.We found that the severity of psoriasis-like skin phenotype was accompanied by changes in the composition of the intestinal microbiota.We performed co-housing and fecal microbial transplantation(FMT)experiments using the K14-VEGF transgenic mouse model of psoriasis and demonstrated that the transfer of intestinal microbiota from mice with severe psoriasis-like skin phenotype exacerbated psoriasiform skin inflammation in mice with mild symptoms,including increasing the infiltration and differentiation of Th17,and increased the abundance of Prevotella,while decreasing that of Parabacteroides distasonis,in the colon.These alterations affected fatty acid metabolism,increasing the abundance of oleic and stearic acids.Meanwhile,gentamicin treatment significantly reduced the abundance of Prevotella and alleviated the psoriasis-like symptoms in both K14-VEGF mice and imiquimod(IMQ)-induced psoriasis-like mice.Indeed,administration of oleic and stearic acids exacerbated psoriasis-like symptoms and increased Th17 and monocyte-derived dendritic cell infiltration in the skin lesion areas in vivo,as well as increased the secretion of IL-23 by stimulating DCs in vitro.At last,we found that,treatment of PDE-4 inhibitor alleviated psoriasis-like phenotype of K14-VEGF mice accompanied by the recovery of intestinal microbiota,including the decrease of Prevotella and increase of Parabacteroides distasonis.Overall,our findings reveal that the intestinal microbiota modulates host metabolism and psoriasis-like skin inflammation in mice,suggesting a new target for the clinical diagnosis and treatment of psoriasis. | Qixiang Zhao Jiadong Yu Hong Zhou Xiaoyan Wang Chen Zhang Jing Hu Yawen Hu Huaping Zheng Fanlian Zeng Chengcheng Yue Linna Gu Zhen Wang Fulei Zhao Pei Zhou Haozhou Zhang Nongyu Huang Wenling Wu Yifan Zhou Jiong Li | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 2 |
| 10 | A New κ-Carrageenase Cgk S from Marine Bacterium Shewanella sp. Kz7显示文摘A new κ-carrageenase gene cgk S was cloned from marine bacterium Shewanella sp. Kz7 by using degenerate and site-finding PCR. The gene was comprised of an open reading frame of 1224 bp, encoding 407 amino acid residues, with a signal peptide of 24 residues. Based on the deduced amino acid sequence, the κ-carrageenase Cgk S was classified into the Glycoside Hydrolase family 16. The cgk S gene was expressed in Escherichia coli, and the recombinant enzyme was purified to homogeneity with a specific activity of 716.8 U mg-1 and a yield of 69%. Recombinant Cgk S was most active at 45℃ and p H 8.0. It was stable at p H 6.0–9.0 and below 30℃. The enzyme did not require Na Cl for activity, although its activity was enhanced by Na Cl. Cgk S degraded κ-carrageenan in an endo-fashion releasing tetrasaccharides and disaccharides as main hydrolysis products. | WANG Linna LI Shangyong ZHANG Shilong LI Jiejing YU Wengong GONG Qianhong | 2015 | Journal of Ocean University of China2015，14，4： | 2 |
| 11 | Potential Deformation and Its Application to the Diagnosis of Heavy Precipitation in Mesoscale Convective Systems显示文摘Many observational studies have shown that deformation, like vertical vorticity and divergence, is closely related to the occurrence and distribution of strong precipitation. In this paper, to involve deformation in precipitation diagnosis, a new parameter called potential deformation(PD) is derived and then applied to precipitation detection within a simulated mesoscale convective system(MCS). It is shown that PD includes both stretching deformation and shearing deformation and shares similar characteristics with deformation insofar as it does not change with the rotating coordinate. Diagnosis of the simulated MCS reveals that PD performs well in tracing the MCS' precipitation. In terms of their distributional pattern, the large-value areas of PD are similar to the precipitation in the different development stages of the MCS. A detailed analysis of the physical processes contained within the PD shows that it can reflect the three-dimensional moisture variation,vertical wind shear and wind deformation within the MCS. These structures are usually a comprehensive reflection of the characteristics of the surface cold pool, rear inflow jet, downward cold air flow and upward warm moist flow within the precipitating convective cells. For this reason, the PD shows much stronger anomalies in the precipitating atmosphere than the non-precipitating atmosphere, which implies considerable potential for its application in detecting heavy precipitation within MCSs. | Na LI Lingkun RAN Linna ZHANG Shouting GAO | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |

| 14 | Light-triggered NO-releasing nanoparticles for treating mice with liver fibrosis显示文摘Liver fibrosis, resulting from chronic liver damage and characterized by the accumulation of extracellular matrix (ECM) proteins, is a characteristic of most types of chronic liver diseases. The activation of hepatic stellate cells (HSC) is considered an essential pathological hallmark in liver fibrosis. Although nitric oxide (NO) can effectively induce HSC apoptosis, the systemic administration of NO is ineffective and may cause severe complications such as hypotension. To overcome this limitation, nanoparticles were designed to target HSCs and release NO locally under the exposure of near infrared light (NIR). To achieve this, upconversion nanoparticle (UCNP) cores were enveloped in mesoporous silica shells (UCNP@mSiO2), which were modified with hyaluronic acid (HA-UCNP@mSiO2) and Roussin’s black salt (RBS). HA molecules recognize and bind to CD44 proteins, which are overexpressed on activated HSCs. Under exposure to a 980-nm NIR laser, the UCNP cores convert the 980-nm wavelength into ultraviolet (UV) light, which then energizes the RBS (NO donors), resulting in an efficient release of NO inside of the HSCs. Once released, NO triggers HSC apoptosis and reverses the liver fibrosis. This targeted and controlled release method provides the theoretical and experimental basis for novel therapeutic approaches to treat hepatic fibrosis. | Hongxia Liang Zhenhua Li Zhigang Ren Qiaodi Jia Linna Guo Shasha Li Hongyu Zhang Shiqi Hu Dashuai Zhu Deliang Shen Zujiang Yu Ke Cheng | 2020 | Nano Research2020，13，8： | 1 |

The hot agarose solution is casted onto a template with patterned Ag nanowires, endowing agarose hydrogel with patterned conductive surface. After further heating treatment, Ag nanowires can be embedded into the agarose hydrogel, which improves the stability of Ag pattern and has no obvious e ffect on the conductivity of hydrogels. The agarose hydrogel with patterned Ag nanowires is certi fied to be an e ffective stretchable electrode to record the motion of joints, which has great potential applications in the field of wearable devices. | Qingquan Han Yang Chen Wei Song Milin Zhang Shengtao Wang Peng Ren Linna Hao Anhe Wang Shuo Bai Jian Yin | 2019 | Bio-Design and Manufacturing2019，2，4： | 1 |
| 16 | Boosting fast interfacial Li^(+)transport in solid-state Li metal batteries via ultrathin Al buffer layer显示文摘Na superionic conductor(NASICON)-type Li_(1.5)Al_(0.5)Ge_(0.5)P_(3)O_(12)(LAGP)solid state electrolytes(SSEs)have attracted significant interests thanks to the prominent ionic conductivity(>10^(–4)S·cm^(–1))at room temperature and superb stability in air.Unfortunately,its application has been hindered by the lithium dendrites and the intrinsic interfacial instability of LAGP towards metallic Li,etc.Herein,by magnetron sputtering(MS),an ultrathin Al film is deposited on the surface of the LAGP pellet(Al-LAGP).By in-situ alloying reaction,the spontaneously formed LiAl buffer layer inhibits the side reaction between LAGP SSEs and Li metal,induces the uniform distribution of interfacial electric field as well.Density functional theory(DFT)calculations demonstrate that the LiAl alloy surface promotes the diffusion of lithium atoms due to the lower energy barrier,thereby inhibiting the formation of lithium dendrites.Consequently,the Li/Al-LAGP-Al/Li symmetric cells show a low resistance of 210Ωand a durable lifespan over 1,200 h at a high current density of 0.1 mA·cm^(-2).Assembled all solid state lithium metal batteries(ASSLMBs)with LiFePO_(4)(LFP)cathode significantly improve cycle stability and rate performance,proving a promising stabilization strategy towards the NASIOCN type electrolyte/anode interface in solid state Li metal batteries. | Shengnan Zhang Qing Sun Guangmei Hou Jun Cheng Linna Dai Jianwei Li Lijie Ci | 2023 | Nano Research2023，16，5： | 1 |

| 19 | CCGD-ESCC: A Comprehensive Database for Genetic Variants Associated with Esophageal Squamous Cell Carcinoma in Chinese Population显示文摘Esophageal squamous-cell carcinoma(ESCC) is one of the most lethal malignancies in the world and occurs at particularly higher frequency in China. While several genome-wide association studies(GWAS) of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma(CCGD-ESCC) database, which contains the associations of 69,593 single nucleotide polymorphisms(SNPs) with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients(survival GWAS) and gene expression(expression quantitative trait loci,eQTL) in 94 ESCC patients. Moreover, this database also provides the associations between8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http://gffzzdf7d528e3a264cb9hn5f5u5vub9bv60kf.ffgz.tsg.suse.edu.cn/ccgd/ESCCdb. | Linna Peng Sijin Cheng Yuan Lin Qionghua Cui Yingying Luo Jiahui Chu Mingming Shao Wenyi Fan Yamei Chen Ai Lin Yiyi Xi Yanxia Sun Lei Zhang Chao Zhang Wen Tan Ge Gao Chen Wu Dongxin Lin | 2018 | Genomics, Proteomics & Bioinformatics2018，16，4： | 1 |
| 20 | Remediation of Organochlorine Pesticide-Contaminated Soils by Surfactant-Enhanced Washing Combined with Activated Carbon Selective Adsorption显示文摘Remediation of organochlorine pesticide (OCP)-contaminated soils is urgently required especially in China. The present study investigated the removal of OCPs from two soils by triton X-100 (TX- 100)-enhanced washing coupled with powdered activated carbon (PAC) adsorption treatment of the solution. Two contaminated soils, including a silt clay contaminated w计h chlordene, dichloro- 2,2-6is(p-chlorophenyl)ethanes (DDDs), and dichlorodiphenyltrichloroethane (DDT) and a sandy loam containing chlordanes and mirex, were selected. Effects of varied operating parameters, including TX-100 dosage, liquid/soil (L/S) ratio, and extraction time, on the contaminant removal were examined. For both soils, OCP removal was clearly enhanced with increasing TX-100 in extraction solution and L/S ratio. Meanwhile, the removal efficacy was also impacted by soil texture and characteristics and contents of the contaminants. Moreover, by using PAC as an absorbent, a significant decrease in the contaminants in the extraction solutions was detected, and TX-100 could be further reused. Our investigation suggests that surfactant-enhanced washing combined with activated carbon selective adsorption would be an alternative to remediate OCP-contaminated soils. | ZHANG Shengtian HE Yue WU Linna WAN Jinzhong YE Mao LONG Tao YAN Zhou JIANG Xin LIN Yusuo LU Xiaohua | 2019 | Pedosphere2019，29，3： | 1 |
