| 1 | Tumor-expressed B7-H3 mediates the inhibition of antitumor T-cell functions in ovarian cancer insensitive to PD-1 blockade therapy显示文摘Although PD-L1/PD-1 blockade therapy has been approved to treat many types of cancers,the majority of patients with solid tumors do not respond well,but the underlying reason remains unclear.Here,we studied ovarian cancer(OvCa),a tumor type generally resistant to current immunotherapies,to investigate PD-1-independent immunosuppression.We found that PD-L1 was not highly expressed in the tumor microenvironment(TME)of human OvCa.Instead,B7-H3,another checkpoint molecule,was highly expressed by both tumor cells and tumor-infiltrating antigen-presenting cells(APCs),which correlated with T-cell exhaustion in patients.Using ID8 OvCa mouse models,we found that B7-H3 expressed on tumor cells,but not host cells,had a dominant role in suppressing antitumor immunity.Therapeutically,B7-H3 blockade,but not PD-1 blockade,prolonged the survival of ID8 tumorbearing mice.Collectively,our results demonstrate that tumor-expressed B7-H3 inhibits the function of CD8^(+)T cells and suggest that B7-H3 may be a target in patients who are not responsive to PD-L1/PD-1 inhibition,particularly OvCa patients. | Dongli Cai Jiaming Li Dingfeng Liu Shanjuan Hong Qin Qiao Qinli Sun Pingping Li Nanan Lyu Tiantian Sun Shan Xie Li Guo Ling Ni Liping Jin Chen Dong | 2020 | Cellular & Molecular Immunology2020，17，3： | 8 |
| 2 | Influence of environmental factors on corrosion damage of aircraft structure显示文摘Corrosion is one of the important structural integrity concerns of aging aircraft, and it is estimated that a significant portion of airframe maintenance budgets is directed towards corrosion-related problems for both military and commercial aircraft. In order to better understand how environmental factors influence the corrosion damage initiation and propagation on aircraft structure and to predict pre-corrosion test pieces of fatigue life and structural integrity of an effective approach, this paper uses the cellular automaton (CA) method to character the effect of electrolyte concentrations, dissolution probabilities, and temperature on the corrosion damage of a metal structure exposed to an aggressive environment, and the procedure for applying the local rules between the cells of the CA to simulate the corrosion damage evolution is formulated. The simulation results show that the different electrolyte concentrations, dissolution probabilities and temperature, the laws of the dissolution current with time are investigated and they obey the time power function. | Keliang Ren,) Shiwu Gao, Pingping Liu, and Yan Dong Department of Physics & Electrical Information, Ningxia University, Ningxia 750021, China | 2011 | Theoretical & Applied Mechanics Letters2011，1，6： | 2 |

| 7 | Electrodeposited synthesis of self-supported Ni-P cathode for efficient electrocatalytic hydrogen generation显示文摘One of the key challenges for electrochemical water splitting is the development of low-cost and efficient hydrogen evolution cathode. In this work, a self-supported Ni-P cathode was synthesized by a facile electrodeposition method. The composition and morphology were characterized by X-ray diffraction,X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy.The Ni-P cathode performed low onset over-potential, good catalytic activity and long-term stability under neutral and alkaline conditions. The mechanism of Ni-P electrode for hydrogen production was discussed by electrochemical impedance spectroscopy. The excellent performance of Ni-P cathode was mainly attributed to the synergistic effect of phosphate anions and the self-supported feature. | Ruixian Wu Yuming Dong Pingping Jiang Guangli Wang Yanmei Chen Xiuming Wu | 2016 | Progress in Natural Science:Materials International2016，26，3： | 1 |

| 13 | Studies on pathways to carbon neutrality for indirect coal liquefaction in China显示文摘The production capacity of indirect coal liquefaction(ICL)in use in China has reached a level of 8 million t/a,which corresponds to a carbon footprint of>60 million t/a.ICL is facing mountainous pressure to reduce its carbon emissions when its development is planned with carbon neutrality as a background objective.This paper studies the pathways that can lead to carbon neutrality for ICL in China,constructing four carbon-neutral pathways for ICL systems with the introduction of green hydrogen,biomass as feedstock and with CCS(carbon capture and storage),which can reduce significant carbon emissions from coal-gasification and water-gas shift processes.The carbon-neutral biomass is used to replace some coal as co-feed to gasification and combustion,leading to reduced carbon emissions as well.Calculations and economic analyses are performed on different carbon-reduction pathways using a carbon-neutral ICL system on a 1 million t/a scale as an example.The results are that the pathway of direct coal substitution with biomass is the lowest carbon-reduction route at RMB 31-125/t CO_(2),substitution with green hydrogen costs the highest at RMB 84-422/t CO_(2) and CCS costs are in the middle at RMB 96-148/t CO_(2).Each pathway has its pros and cons,and a combination of the three may be used for the best outcome.Furthermore,a comprehensive study and systematic summation of the critical technological processes and their underlying challenges for carbon-neutral ICL together with direction for a technological breakthrough are presented.These ICL carbon-reduction pathways presented in this paper are capable of realizing an integrated development between fossil and renewable energy sources,helping the carbon-intense coal-chemical industries to achieve their goals of carbon peak and carbon neutrality. | Chufu Li Yonglong Li Ming Xu Yan Gong Siqi Gong Peng Wang Pingping Li Binqi Dong Zhuowu Men | 2021 | Clean Energy2021，5，4： | 1 |

| 15 | Axiotaxy driven growth of belt-shaped InAs nanowires in molecular beam epitaxy显示文摘In this study,we demonstrate the axiotaxy driven growth of belt-shaped InAs nanowires using Au catalysts by molecular beam epitaxy.It is found that,the zinc-blende structured InAs nanowires,with the features of[113]growth direction and extensive{110}side-surfaces,are induced by catalysts in Au–In α phase through the axiotaxy growth,in which the lattice mismatch between the projections of atomic planes onto nanowire/catalyst interfaces is minimized by forming extraordinary tilted interfaces.Our atomic-resolution in situ TEM heating experiments show that the catalysts remained in the solid state of Au–In α phase during the axiotaxy growth,by which the vapor–solid–solid growth mechanism can be confirmed.Through manipulating the growth direction,this unusual growth mechanism can provide a practical pathway to control the morphology of the low-dimensional nanomaterials,from conventional nanowires to belt-shaped nanowires utilizing a significant lateral growth,simply using nanoparticles as catalyst. | Qiang Sun Dong Pan Xutao Zhang Jianhua Zhao Pingping Chen Wei Lu Jin Zou | 2021 | Nano Research2021，14，7： | 0 |
| 16 | Scheduling optimization for upstream dataflows in edge computing显示文摘Edge computing can alleviate the problem of insufficient computational resources for the user equipment,improve the network processing environment,and promote the user experience.Edge computing is well known as a prospective method for the development of the Internet of Things(IoT).However,with the development of smart terminals,much more time is required for scheduling the terminal high-intensity upstream dataflow in the edge server than for scheduling that in the downstream dataflow.In this paper,we study the scheduling strategy for upstream dataflows in edge computing networks and introduce a three-tier edge computing network architecture.We propose a Time-Slicing Self-Adaptive Scheduling(TSAS)algorithm based on the hierarchical queue,which can reduce the queuing delay of the dataflow,improve the timeliness of dataflow processing and achieve an efficient and reasonable performance of dataflow scheduling.The experimental results show that the TSAS algorithm can reduce latency,minimize energy consumption,and increase system throughput. | Haohao Wang Mengmeng Sun Lianming Zhang Pingping Dong Yehua Wei Jing Mei | 2023 | Digital Communications and Networks2023，9，6： | 0 |
| 17 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 18 | Preparation of Cu-,Zn-,Co-Zeolites and Application for Adsorptive Desulfurization of Saudi Arabian Medium Crude显示文摘A series of Cu(II)-, Zn(II)-, Co(II)-loaded zeolites were successfully prepared by liquid phase ion-exchange method and characterized by X-ray diffraction(XRD), N2-adsorption specific surface area measurement(BET), X-ray fluorescence(XRF), and scanning electron microscopy(SEM) techniques. The adsorptive desulfurization performance of different adsorbents for treating Saudi Arabian medium crude oil was investigated, and the results showed that desulfurization efficiency declined in the following order: Zn(II)X > Cu(II)Y > Co(II)X > Cu(II)X > Co(II)Y> Zn(II)Y. The best desulfurization efficiency of 41.01% was achieved by using Zn(II)X as the adsorbent under the optimized conditions.The desulfurization performance of Zn(II)X in different distillates showed that a better performance was obtained in heavy petroleum fractions. Furthermore, the distribution of sulfur compounds in distillates after desulfurization was analyzed and the results showed that the adsorbent Zn(II)X could preferably adsorb aromatic sulfides such as thiophenes,benzothiophenes, and dibenzothiophenes. These results suggested that the π-complexation between zinc ions and sulfides would be crucial to the excellent desulfurization efficiency of Zn(II)X. In addition, the used adsorbent could be regenerated by heating at 700 °C in air, and around 84% of desulfurization capacity was recovered after the first cycle of regeneration. | Song Linhua Wang Zi Yan Yixuan LüBaoxiu Wu Pingping Zhao Xiaodong Liu Dong | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，3： | 0 |
| 19 | Split-TCP Based Acceleration Gateway over Packet Lossy Networks显示文摘The conservative Additive Increase Multiplicative Decrease mechanism of traditional TCP causes the link under-utilization in the Wide Area Networks(WANs) due to the WANs' intrinsic nature of high latency and high packet loss.To alleviate the problem,we present the design and implantation of STAG,an Acceleration Gateway with Split-TCP in the paper.STAG is built on embedded network equipment and acts as a transparent proxy.In STAG,a new improved congestion control method named Rapid TCP is adopted,which determines whether or not to decrease the congestion window based on the packet loss trend.In particular,in the fast recovery phase,it chooses different window adjustment strategies based on the current size of congestion window to achieve higher utilization.The performance validation of STAG is done on both our emulation testbed and the real wide area network.The results show that STAG with Rapid TCP effectively adapts to the high loss network environment and significantly speeds up the applications without loss of fairness. | DONG Pingping WANG Jianxin HUANG Jiawei WANG Haodong | 2015 | China Communications2015，12，5： | 0 |
| 20 | Laminae characteristics of gas-bearing shale fine-grained sediment of the Silurian Longmaxi Formation of Well Wuxi 2 in Sichuan Basin,SW China显示文摘Based on various test data, the composition, texture, structure and lamina types of gas-bearing shale were determined based on Well Wuxi 2 of the Silurian Longmaxi Formation in the Sichuan Basin. Four types of lamina, namely organic-rich lamina, organic-bearing lamina, clay lamina and silty lamina, are developed in the Longmaxi Formation of Well Wuxi 2, and they form 2 kinds of lamina set and 5 kinds of beds. Because of increasing supply of terrigenous clasts and enhancing hydrodynamics and associated oxygen levels, the contents of TOC and brittle mineral reduce and content of clay mineral increases gradually as the depth becomes shallow. Organic-rich lamina, organic-rich + organic-bearing lamina set and organic-rich bed dominate the small layers 1-3 of Member 1 of the Longmaxi Formation, suggesting anoxic and weak hydraulic depositional setting. Organic-rich lamina, along with organic-bearing lamina and silty lamina, appear in small layer 4, suggesting increased oxygenated and hydraulic level. Small layers 1-3 are the best interval and drilling target of shale gas exploration and development. | SHI Zhensheng QIU Zhen DONG Dazhong LU Bin LIANG Pingping ZHANG Mengqi | 2018 | Petroleum Exploration and Development2018，45，2： | 0 |
