| 3 | EFFECT: an efficient flexible privacy-preserving data aggregation scheme with authentication in smart grid显示文摘Smart grid is considered as a promising approach to solve the problems of carbon emission and energy crisis. In smart grid, the power consumption data are collected to optimize the energy utilization.However, security issues in communications still present practical concerns. To cope with these challenges, we propose EFFECT, an efficient flexible privacy-preserving aggregation scheme with authentication in smart grid. Specifically, in the proposed scheme, we achieve both data source authentication and data aggregation in high efficiency. Besides, in order to adapt to the dynamic smart grid system, the threshold for aggregation is adjusted according to the energy consumption information of each particular residential area and the time period, which can support fault-tolerance while ensuring individual data privacy during aggregation.Detailed security analysis shows that our scheme can satisfy the desired security requirements of smart grid.In addition, we compare our scheme with existing schemes to demonstrate the effectiveness of our proposed scheme in terms of low computational complexity and communication overhead. | Zhitao GUAN Yue ZHANG Liehuang ZHU Longfei WU Shui YU | 2019 | Science China(Information Sciences)2019，62，3： | 8 |
| 4 | LIN28 coordinately promotes nucleolar/ribosomal functions and represses the 2C-like transcriptional program in pluripotent stem cells显示文摘LIN28 is an RNA binding protein with important roles in early embryo development,stem cell differentiation/re-programming,tumorigenesis and metabolism.Previous studies have focused mainly on its role in the cytosol where it interacts with Let-7 microRNA precursors or mRNAs,and few have addressed LIN28's role within the nucleus.Here,we show that LIN28 displays dynamic temporal and spatial expression during murine embryo development.Maternal LIN28 expression drops upon exit from the 2-cell stage,and zygotic LIN28 protein is induced at the forming nucleolus during 4-cell to blas-tocyst stage development,to become dominantly expressed in the cytosol after implantation.In cultured pluripotent stem cells(PSCs),loss of LIN28 led to nucleolar stress and activation of a 2-cell/4-cell-like transcriptional program characterized by the expression of endogenous retrovirus genes.Mechanistically,LIN28 binds to small nucleolar RNAs and rRNA to maintain nucleolar integrity,and its loss leads to nucleolar phase separation defects,ribosomal stress and activation of P53 which in turn binds to and activates 2C transcription factor Dux.LIN28 also resides in a complex containing the nucleolar factor Nucleolin(NCL)and the transcrip-tional repressor TRIM28,and LIN28 loss leads to reduced occupancy of the NCL/TRIM28 complex on the Dux and rDNA loci,and thus de-repressed Dux and reduced rRNA expression.Lin28 knockout cells with nucleolar stress are more likely to assume a slowly cycling,translationally inert and anabolically inactive state,which is a part of previously unappreciated 2C-like transcriptional program.These findings elucidate novel roles for nucleolar LIN28 in PSCs,and a new mechanism linking 2C program and nucleolar functions in PSCs and early embryo development. | Zhen Sun Hua Yu Jing Zhao Tianyu Tan Hongru Pan Yuqing Zhu Lang Chen Cheng Zhang Li Zhang Anhua Lei Yuyan Xu Xianju Bi Xin Huang Bo Gao Longfei Wang Cristina Correia Ming Chen Qiming Sun Yu Feng Li Shen Hao Wu Jianlong Wang Xiaohua Shen George Q.Daley Hu Li Jin Zhang | 2022 | Protein & Cell2022，13，7： | 4 |

| 6 | Nonvolatile memristor based on heterostructure of 2D room-temperature ferroelectric α-In2Se3 and WSe2显示文摘Two-dimensional(2D) ferroelectricity is considered to have significant potential for information storage in the future. Semiconducting ferroelectrics that are stable at room temperature afford many possibilities for the assembly of various high-performance heterostructures and fabricating multifuntional devices.Herein, we report the synthesis of a stable van der Waals(vd W) single-crystal semiconductor α-In2 Se3.Piezoresponse force microscopy(PFM) measurements demonstrated the out-of-plane ferroelectricity in ~15 layers α-In2 Se3 at room temperature. Both ferroelectric domains with opposite polarization and the tested amplitude and phase curve proved that this semiconductor exhibits hysteresis behavior during polarization.In the α-In2Se3/WSe2 vertical heterostructure device, the switchable diode effect and nonvolatile memory phenomenon showed a high on/off ratio and a small switching voltage. The distinct resistance switches were further analyzed by band alignment of the heterostructure under different polarizations by first principle calculations. Nonvolatile memory based on vd W ferroelectric heterostructure could provide a novel platform for developing 2 D room-temperature ferroelectrics in information storage. | Huai YANG Mengqi XIAO Yu CUI Longfei PAN Kai ZHAO Zhongming WEI | 2019 | Science China(Information Sciences)2019，62，12： | 3 |
| 7 | Combination therapy using microwave ablation and d-mannose-chelated iron oxide nanoparticles inhibits hepatocellular carcinoma progression显示文摘Despite being a common therapy for hepatocellular carcinoma(HCC),insufficient thermal ablation can leave behind tumor residues that can cause recurrence.This is believed to augment M2 inflammatory macrophages that usually play a pro-tumorigenic role.To address this problem,we designed D-mannose-chelated iron oxide nanoparticles(man-IONPs) to polarize M2-like macrophages into the antitumor Ml phenotype.In vitro and in vivo experiments demonstrated that man-IONPs specifically targeted M2-like macrophages and accumulated in peri-ablation zones after macrophage infiltration was augmented under insufficient microwave ablation(MWA).The nanoparticles simultaneously induced polarization of pro-tumorigenic M2 macrophages into antitumor M1 phenotypes,enabling the transformation of the immunosuppressive microenvironment into an immunoactivating one.Post-MWA macrophage polarization exerted robust inhibitory effects on HCC progression in a well-established orthotopic liver cancer mouse model.Thus,combining thermal ablation with man-IONPs can salvage residual tumors after insufficient MWA.These results have strong potential for clinical translation. | Rui Cui Luo Wang Dongyun Zhang Kun Zhang Jianping Dou Linan Dong Yixuan Zhang Jiapeng Wu Longfei Tan Jie Yu Ping Liang | 2022 | Acta Pharmaceutica Sinica B2022，12，9： | 2 |
| 8 | An SDN Oriented Loop Detection Mechanism Based on TTL Statistics显示文摘The rise of the network has injected new impetus into the development of traditional networks.Due to the complexity of the network itself and its network programmability,there is a risk of routing loops occurring in the SDN network.This paper proposes a loop detection mechanism.According to the Time To Live(TTL)value of the loop packet,there is approximately periodicity in the same loop.We use sFlow to count the number of packets corresponding to each TTL value of a switch in the loop over a period of time,and perform discrete Fourier transform on the obtained finite-length sequence to observe its frequency domain performance and determine whether there are periodic features.By doing so,it is determined whether there is a routing loop,and the purpose of passively detecting the routing loop is achieved.Compared to existing algorithms,it has advantages in real-time,scalability and false positive rate.The experimental results show that the routing loop detection algorithm based on TTL statistics in this paper still maintains high judgment accuracy under the scenarios of lower stream sampling rate and smaller detection period. | Tao Yu Longfei Yu Diyue Chen Hongyan Cui Jilong Wang | 2020 | China Communications2020，17，6： | 2 |
| 9 | Multi-Component and Multi-Point Trace Gas Sensing in Wavelength Modulation Spectroscopy Based on Wavelength Stabilization显示文摘Multi-component and multi-point trace gas sensing in the wavelength modulation spectroscopy is demonstrated based on the frequency-division multiplexing and time-division multiplexing technology.A reference photodetector is connected in series with a reference gas cell with the constant concentration to measure the second-harmonics peak of the components for wavelength stabilization in real time.The central wavelengths of the distributed feedback lasers are locked to the target gas absorption centers by the reference second-harmonics signal using a digital proportional-integral-derivative controller.The distributed feedback lasers with different wavelengths and modulation frequencies are injected into the gas cell to achieve multi-components gas measurement by the frequency-division multiplexing technology.In addition,multi-point trace gas sensing is achieved by the time-division multiplexing technology using a photoswitch and a relay unit.We use this scheme to detect methane(CH4)at 1650.9 nm and water vapor(H2O)at 1368.597 nm as a proof of principle with the gas cell path length of 10 cm.The minimum detection limits achieved for H2O and CH4 are 1.13 ppm and 11.85 ppm respectively,with three-point gas cell measurement;thus 10.5-fold and 10.1-fold improvements are achieved in comparison with the traditional wavelength modulation spectroscopy.Meanwhile,their excellent R-square values reach 0.9983 and 0.99564 for the concentration ranges of 500 ppm to 2000 ppm and 800 ppm to 2700 ppm,respectively. | Zongliang WANG Jun CHANG Huishan YU Cunwei TIAN Hao ZHANG Xiukun ZHANG Longfei TANG Qinduan ZHANG Yiwen FENG | 2019 | Photonic Sensors2019，9，4： | 2 |
| 10 | Purification and molecular weight distribution of a key exopolysaccharide component of Bacillus megaterium TF10显示文摘Extracellular polymeric substances(EPS) are organic metabolic compounds excreted by microorganisms. They largely impact microbial aggregate structures and functions.Extracellular polysaccharides(EP) in EPS are responsible for the formation of microbial aggregates. In this work, we successfully separated and characterized EP from EPS of the bacterium Bacillus megaterium TF10. Extraction of EP from EPS was optimized using Sevag's reagent. Chemical characteristics, functional groups, and molecular weight(MW) distribution of EP were compared with the harvested EPS and soluble microbial products(SMP). We found that the polymers of lower MW and free proteins were successfully removed by Sevag's reagent. The higher MW components of EPS were predominantly polysaccharides,while the polymers of lower MW tended to secrete to the supernatant and were described as SMP. A part of the proteins in the EP was polysaccharide-bonded. Our results can be further used in elucidating the complex flocculation mechanisms in which EP play a major role. | Lingling Wang Longfei Wang Qingshan Shi Hanqing Yu | 2018 | Journal of Environmental Sciences2018，30，1： | 2 |

| 12 | Natural astaxanthin enhanced antioxidant capacity and improved semen quality through the MAPK/Nrf2 pathway in aging layer breeder roosters显示文摘Background:Natural astaxanthin(ASTA)has strong antioxidant properties and has been widely used as a health product to improve human health.However,the effects of ASTA on the reproductive performance of aging roosters have been poorly studied.We aimed to investigate the effects of dietary ASTA on semen quality and antioxidant capacity in aging roosters and to explore the potential mechanism of semen quality change via antioxidation defense system.Methods:In the present study,9653-week-old Jinghong No.1 layer breeder roosters were fed a corn-soybean meal basal diet containing 0,25,50,or 100 mg/kg ASTA for 6 weeks.Results:Semen quality in the ASTA groups remarkably improved than that in the control group,and antioxidant activities,the abilities to scavenge hydroxyl radicals and superoxide anions,increased gradually with ASTA addition(P<0.05).In addition,the mRNA levels of antioxidant enzymes as well as the mRNA and protein levels of the mitogen-activated protein kinase(MAPK)and nuclear factor-erythroid 2-related factor 2(Nrf2)were markedly increased in the 50-100 mg/kg ASTA group(P<0.05).Conclusions:Collectively,these results demonstrate that dietary ASTA may improve semen quality by increasing antioxidant enzyme activities and the ability to scavenge hydroxyl radicals,which may be related to upregulation of the MAPK/Nrf2 pathway. | Shan Gao Nuo Heng Fang Liu Yong Guo Yu Chen Liang Wang Hemin Ni Xihui Sheng Xiangguo Wang Kai Xing Longfei Xiao Xiaolong Qi | 2022 | Journal of Animal Science and Biotechnology2022，13，2： | 2 |

| 15 | Formation, preservation and connectivity control of organic pores in shale显示文摘In view of strong heterogeneity and complex formation and evolution of organic pores,field emission scanning electron microscopy(FESEM),Raman spectrum and fluid injection+CT/SEM imaging technology were used to study the macerals,organic pores and connectivity of organic pores in the lower Paleozoic organic-rich shale samples from Southern China.Combined with the mechanism of hydrocarbon generation and expulsion and pore forming mechanism of organic matter-based activated carbon,the relationships between organic pore development and the organic matter type,hydrocarbon generation process,diagenesis and pore pressure were explored to reveal the controlling factors of the formation,preservation and connectivity of organic pores in shale.(1)The generation of organic pores goes on through the whole hydrocarbon generation process,and is controlled by the type,maturity and decomposition of organic matter;the different hydrocarbon generation components and differential hydrocarbon-generation evolution of kerogen and solid asphalt lead to different pore development characteristics;organic pores mainly develop in solid bitumen and hydrogen-rich kerogen.(2)The preservation of organic pores is controlled by maturity and diagenesis,including the steric hindrance effect of in-situ hydrocarbon retention,rigid mineral framework formed by recrystallization,the coupling mechanism of pore-fluid pressure and shale brittleness-ductility transition.(3)The Ro of 4.0%is the maturity threshold of organic pore extinction,the shale layers with Ro larger than 3.5%have high risk for shale gas exploration,these shale layers have low gas contents,as they were in an open state before uplift,and had high hydrocarbon expulsion efficiency and strong aromatization,thus having the'congenital deficiency'of high maturity and pore densification.(4)The pores in the same organic matter particle have good connectivity;and the effective connectivity between different organic matter pores and inorganic pores and fractures depends on the abundance and distribution of organic matter,and development degree of pores and fractures in the shale;the accumulation,preservation and laminar distribution of different types of organic matter in high abundance is the prerequisite for the development and connection of organic pores,grain margin fractures and bedding fractures in reservoir. | BORJIGIN Tenger LU Longfei YU Lingjie ZHANG Wentao PAN Anyang SHEN Baojian WANG Ye YANG Yunfeng GAO Zhiwei | 2021 | Petroleum Exploration and Development2021，48，4： | 1 |

| 20 | Improved Yield Prediction of Ratoon Rice Using Unmanned Aerial Vehicle-Based Multi-Temporal Feature Method显示文摘Pre-harvest yield prediction of ratoon rice is critical for guiding crop interventions in precision agriculture.However,the unique agronomic practice(i.e.,varied stubble height treatment)in rice ratooning could lead to inconsistent rice phenology,which had a significant impact on yield prediction of ratoon rice.Multi-temporal unmanned aerial vehicle(UAV)-based remote sensing can likely monitor ratoon rice productivity and reflect maximum yield potential across growing seasons for improving the yield prediction compared with previous methods.Thus,in this study,we explored the performance of combination of agronomic practice information(API)and single-phase,multi-spectral features[vegetation indices(VIs)and texture(Tex)features]in predicting ratoon rice yield,and developed a new UAV-based method to retrieve yield formation process by using multi-temporal features which were effective in improving yield forecasting accuracy of ratoon rice.The results showed that the integrated use of VIs,Tex and API(VIs&Tex+API)improved the accuracy of yield prediction than single-phase UAV imagery-based feature,with the panicle initiation stage being the best period for yield prediction(R^(2) as 0.732,RMSE as 0.406,RRMSE as 0.101).More importantly,compared with previous multi-temporal UAV-based methods,our proposed multi-temporal method(multi-temporal model VIs&Tex:R^(2) as 0.795,RMSE as 0.298,RRMSE as 0.072)can increase R^(2) by 0.020-0.111 and decrease RMSE by 0.020-0.080 in crop yield forecasting.This study provides an effective method for accurate pre-harvest yield prediction of ratoon rice in precision agriculture,which is of great significance to take timely means for ensuring ratoon rice production and food security. | ZHOU Longfei MENG Ran YU Xing LIAO Yigui HUANG Zehua LÜZhengang XU Binyuan YANG Guodong PENG Shaobing XU Le | 2023 | Rice science2023，30，3： | 0 |
