| 1 | Hydrogeochemical and Isotopic Evidence for Flow Paths of Karst Waters Collected in the Heshang Cave,Central China显示文摘Understanding of hydrological processes in caves is important to help us interpret paleoclimate records from speleothems. In this study,we integrated hydrogeological and hydrogeochemical properties to characterize the hydraulic behavior of karst waters in the Heshang Cave,Central China. Using geological and topographical analyses,we identified regional watershed boundaries and hydrogeological connections that were controlled by anticlinal geometry and faults. Water samples were collected from the Heshang Cave and potential recharge sites. Geochemical data of c(Sr2+)/c(Ca2+) and c(Mg2+)/c(Ca2+) ratios suggest that the drainage system in Heshang Cave consists of two flow paths. For vadose waters,including drip water and rimstone pool water,c(Sr2+)/c(Ca2+) ratio ranges from 0.000 6 to 0.001 1,and c(Mg2+)/c(Ca2+) ratio ranges from 0.97 to 1.1,indicating that recharge was mainly from rainfall infiltration through the overlying Cambrian dolomite stratum. In contrast,slope current and underground river waters have higher c(Sr2+)/c(Ca2+) ratios(values from 0.002 2 to 0.002 8),and lower c(Mg2+)/c(Ca2+) ratios(values from 0.50 to 0.64). These waters show homogeneous isotopic composition(δ18O:-7.15‰–-6.95‰; δD:-52.73‰–-51.31‰),implying recharge of allogeneic water from the Xiaoer River via karst conduits that pass through Ordovician limestone and Cambrian dolomite stratum. | Xiang Long Ziyong Sun Aiguo Zhou Deliang Liu | 2015 | Journal of Earth Science2015，26，1： | 18 |
| 2 | New strategy for designing orangish-redemitting phosphor via oxygen-vacancyinduced electronic localization显示文摘Phosphor-converted white-light-emitting diodes(pc-WLED)have been extensively employed as solid-state lighting sources,which have a very important role in people’s daily lives.However,due to the scarcity of the red component,it is difficult to realize warm white light efficiently.Hence,red-emitting phosphors are urgently required for improving the illumination quality.In this work,we develop a novel orangish-red La_(4)GeO_(8):Bi^(3+) phosphor,the emission peak of which is located at 600 nm under near-ultraviolet(n-UV)light excitation.The full width at half maximum(fwhm)is 103 nm,the internal quantum efficiency(IQE)exceeds 88%,and the external quantum efficiency(EQE)is 69%.According to Rietveld refinement analysis and density functional theory(DFT)calculations,Bi^(3+) ions randomly occupy all La sites in orthorhombic La_(4)GeO_(8).Importantly,the oxygen-vacancy-induced electronic localization around the Bi3+ions is the main reason for the highly efficient orangish-red luminescence.These results provide a new perspective and insight from the local electron structure for designing inorganic phosphor materials that realize the unique luminescence performance of Bi^(3+) ions. | Yi Wei Gongcheng Xing Kang Liu Guogang Li Peipei Dang Sisi Liang Min Liu Ziyong Cheng Dayong Jin Jun Lin | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 3 | Estimating regional coal resource efficiency in China using three-stage DEA and bootstrap DEA models显示文摘Based on three-stage data envelopment analysis(DEA) model estimates of resource utilization efficiency of coal,we selected 29 provinces from China's 2012 input-output data and used the bootstrap DEA model to correct the bias.The results show that the mean overall technical efficiency,pure technical efficiency,and scale efficiency was 0.833,0.998,and 0.711 in 2012,respectively.Moreover,the comprehensive technical efficiency score indicates that the scale is invalid.Area utilization efficiencies for the eastern,central,and western regions were 0.917,0.731,and 0.629,respectively.The results prove that there are significant differences in the distribution of coal resources utilization efficiency across regions. | Cui Yijia Huang Guoliang Yin Ziyong | 2015 | International Journal of Mining Science and Technology2015，25，5： | 10 |
| 4 | Molecular mechanisms underlying the effects of acupuncture on neuropathic pain显示文摘Acupuncture has been used to treat neuropathic pain for a long time,but its mechanisms of action remain unknown.In this study,we observed the effects of electroacupuncture and manua acupuncture on neuropathic pain and on ephrin-B/EphB signaling in rats models of chronic constriction injury-induced neuropathic pain.The results showed that manual acupuncture and electroacupuncture significantly reduced mechanical hypersensitivity following chronic constriction injury,especially electroacupuncture treatment.Real-time PCR results revealed that ephrin-B1/B3and EphB1/B2 mRNA expression levels were significantly increased in the spinal dorsal horns of chronic constriction injury rats.Electroacupuncture and manual acupuncture suppressed the high expression of ephrin-B1 mRNA,and elevated EphB3/B4 mRNA expression.Electroacupuncture significantly enhanced the mRNA expression of ephrin-B3 and EphB3/B6 in the dorsal horns of neuropathic pain rats.Western blot results revealed that electroacupuncture in particular,and manual acupuncture,significantly up-regulated ephrin-B3 protein levels in rat spinal dorsal horns The results of this study suggest that acupuncture could activate ephrin-B/EphB signaling in neuropathic pain rats and improve neurological function. | Ziyong Ju Huashun Cui Xiaohui Guo Huayuan Yang Jinsen He Ke Wang | 2013 | Neural Regeneration Research2013，8，25： | 8 |
| 5 | Additive manufacturing of thin electrolyte layers via inkjet printing of highly-stable ceramic inks显示文摘Inkjet printing is a promising alternative for the fabrication of thin film components for solid oxide fuel cells(SOFCs) due to its contactless, mask free, and controllable printing process. In order to obtain satisfying electrolyte thin layer structures in anode-supported SOFCs, the preparation of suitable electrolyte ceramic inks is a key. At present, such a kind of 8 mol% Y_(2)O_(3)-stabilized ZrO_(2)(8 YSZ) electrolyte ceramic ink with long-term stability and high solid loading(> 15 wt%) seems rare for precise inkjet printing, and a number of characterization and performance aspects of the inks, such as homogeneity, viscosity, and printability, should be studied. In this study, 8 YSZ ceramic inks of varied compositions were developed for inkjet printing of SOFC ceramic electrolyte layers. The dispersing effect of two types of dispersants, i.e., polyacrylic acid ammonium(PAANH4) and polyacrylic acid(PAA), were compared. The results show that ultrasonic dispersion treatment can help effectively disperse the ceramic particles in the inks. PAANH4 has a better dispersion effect for the inks developed in this study. The inks show excellent printable performance in the actual printing process. The stability of the ink can be maintained for a storage period of over 30 days with the help of initial ultrasonic dispersion. Finally, micron-size thin 8 YSZ electrolyte films were successfully fabricated through inkjet printing and sintering, based on the as-developed high solid loading 8 YSZ inks(20 wt%). The films show fully dense and intact structural morphology and smooth interfacial bonding, offering an improved structural quality of electrolyte for enhanced SOFC performance. | Zhongqi Zhu Zhiyuan Gong Piao Qu Ziyong Li Sefiu Abolaji Rasaki Zhiyuan Liu Pei Wang Changyong Liu Changshi Lao Zhangwei Chen | 2021 | Journal of Advanced Ceramics2021，10，2： | 7 |
| 6 | Sedimentation Rate Rhythms:Evidence from Filling of the Tarim Basin,Northwest China显示文摘Variations of sedimentation rate within a basin over geologic time are a time series that can be filtered into several cyclic wave curves. Based on back-stripping and the empirical mode decomposition method, the cores from 14 wells in the Tarim Basin were selected to do filtering analysis. Four cycles or quasi-cycles(33 Ma, 64.4 Ma, 103.6 Ma, and 224 Ma) were obtained. Among these, the 33 Ma period, which was related to the internal earth activity, an external force, or a combination of the two, was the most obvious. The 64.4 Ma period corresponded to the solar system crossing the galaxy plane or the periodic melting of inner-earth material. The 103.6 Ma period was related with plate collisional tectonism around the Tarim Plate. The 224 Ma period was related to one galaxy year and may also be related to the aesthenospherical convection cycle. | CHEN Shuping JIN Zhijun WANG Yi ZHOU Ziyong LI Jingchang YANG Weili | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 6 |
| 7 | EARS: Intelligence-Driven Experiential Network Architecture for Automatic Routing in Software-Defined Networking显示文摘Software-Defined Networking(SDN)adapts logically-centralized control by decoupling control plane from data plane and provides the efficient use of network resources.However,due to the limitation of traditional routing strategies relying on manual configuration,SDN may suffer from link congestion and inefficient bandwidth allocation among flows,which could degrade network performance significantly.In this paper,we propose EARS,an intelligence-driven experiential network architecture for automatic routing.EARS adapts deep reinforcement learning(DRL)to simulate the human methods of learning experiential knowledge,employs the closed-loop network control mechanism incorporating with network monitoring technologies to realize the interaction with network environment.The proposed EARS can learn to make better control decision from its own experience by interacting with network environment and optimize the network intelligently by adjusting services and resources offered based on network requirements and environmental conditions.Under the network architecture,we design the network utility function with throughput and delay awareness,differentiate flows based on their size characteristics,and design a DDPGbased automatic routing algorithm as DRL decision brain to find the near-optimal paths for mice and elephant flows.To validate the network architecture,we implement it on a real network environment.Extensive simulation results show that EARS significantly improve the network throughput and reduces the average packet delay in comparison with baseline schemes(e.g.OSPF,ECMP). | Yuxiang Hu Ziyong Li Julong Lan Jiangxing Wu Lan Yao | 2020 | China Communications2020，17，2： | 4 |
| 8 | An Efficient Bar Code Image Recognition Algorithm for Sorting System显示文摘In the sorting system of the production line,the object movement,fixed angle of view,light intensity and other reasons lead to obscure blurred images.It results in bar code recognition rate being low and real time being poor.Aiming at the above problems,a progressive bar code compressed recognition algorithm is proposed.First,assuming that the source image is not tilted,use the direct recognition method to quickly identify the compressed source image.Failure indicates that the compression ratio is improper or the image is skewed.Then,the source image is enhanced to identify the source image directly.Finally,the inclination of the compressed image is detected by the barcode region recognition method and the source image is corrected to locate the barcode information in the barcode region recognition image.The results of multitype image experiments show that the proposed method is improved by 5+times computational efficiency compared with the former methods,and can recognize fuzzy images better. | Desheng Zheng Ziyong Ran Zhifeng Liu Liang Li Lulu Tian | 2020 | Computers, Materials & Continua2020，，9： | 3 |
| 9 | Microstructure and Phase Transformation of a Niobium-rich TiAl-based Alloy Containing Boron and Carbon显示文摘Microstructure and phase transformation of Ti46Al8Nb0.5B0.2C alloy have been investigated.X-ray diffraction (XRD),optical microscopy (OM),scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results show that as-cast and hot isostatic pressing (HIP) alloy mainly composed of γ and α 2 phase have fully lamellar microstructure with point-like or ribbon-like TiB 2 distributing in lamellar colony or at grain boundary.The mean size of lamellar colony is about 150 and 450 μm for as-cast and HIP alloy,respectively.The lamellar spacing is about 550 and 600 nm for as-cast and HIP alloy,respectively.It has been found that cooling rates and quenching temperatures have significant effect on phase transformation of Ti46Al8Nb0.5B0.2C alloy.When the alloy is treated at 1380℃ for 1 h and cooled from α domain,water cooling leads to complete α→α 2 transformation,oil cooling leads to predominant α→α 2 and part α→γ m transformation,air cooling leads to α→α + γ p2 →L(α + γ) →L(α 2 + γ) transformation,and furnace cooling leads to α→α + γ p3 →L(α + γ) →L(α 2 + γ) transformation.However,when the alloy is treated at 1400℃ for 1 h and cooled from α domain,water cooling leads to predominant α→α 2 and part α→α + γ p4 →γ m transformation,oil cooling leads to α→α + γ p5 →γ m transformation,air cooling leads to α→α + γ p6 →L(α + γ) →L(α 2 + γ) transformation,and furnace cooling leads to α→α + γ p7 →L(α + γ) →L(α 2 + γ) transformation.Microstructural evolution of the alloy during various heat treatments has been examined and the phase transformation mechanisms have been elucidated.Based on the experimental observation,schematic CCT diagrams for the alloy have been given. | Ziyong Chen Xianglin Su Zhilei Xiang Zuoren Nie | 2012 | Journal of Materials Science & Technology2012，28，5： | 3 |
| 10 | Applying Stack Bidirectional LSTM Model to Intrusion Detection显示文摘Nowadays,Internet has become an indispensable part of daily life and is used in many fields.Due to the large amount of Internet traffic,computers are subject to various security threats,which may cause serious economic losses and even endanger national security.It is hoped that an effective security method can systematically classify intrusion data in order to avoid leakage of important data or misuse of data.As machine learning technology matures,deep learning is widely used in various industries.Combining deep learning with network security and intrusion detection is the current trend.In this paper,the problem of data classification in intrusion detection system is studied.We propose an intrusion detection model based on stack bidirectional long short-term memory(LSTM),introduce stack bidirectional LSTM into the field of intrusion detection and apply it to the intrusion detection.In order to determine the appropriate parameters and structure of stack bidirectional LSTM network,we have carried out experiments on various network structures and parameters and analyzed the experimental results.The classic KDD Cup’1999 dataset was selected for experiments so that we can obtain convincing and comparable results.Experimental results derived from the KDD Cup’1999 dataset show that the network with three hidden layers containing 80 LSTM cells is superior to other algorithms in computational cost and detection performance due to stack bidirectional LSTM model’s ability to review time and correlate with connected records continuously.The experiment shows the effectiveness of stack bidirectional LSTM network in intrusion detection. | Ziyong Ran Desheng Zheng Yanling Lai Lulu Tian | 2020 | Computers, Materials & Continua2020，，10： | 2 |

| 17 | ESMD-Flow: An Intelligent Flow Forwarding Scheme with Endogenous Security Based on Mimic Defense in Space-Air-Ground Integrated Network显示文摘The Space-Air-Ground Integrated Network(SAGIN) realizes the integration of space, air,and ground networks, obtaining the global communication coverage.Software-Defined Networking(SDN) architecture in SAGIN has become a promising solution to guarantee the Quality of Service(QoS).However, the current routing algorithms mainly focus on the QoS of the service, rarely considering the security requirement of flow. To realize the secure transmission of flows in SAGIN, we propose an intelligent flow forwarding scheme with endogenous security based on Mimic Defense(ESMD-Flow). In this scheme, SDN controller will evaluate the reliability of nodes and links, isolate malicious nodes based on the reliability evaluation value, and adapt multipath routing strategy to ensure that flows are always forwarded along the most reliable multiple paths. In addition, in order to meet the security requirement of flows, we introduce the programming data plane to design a multiprotocol forwarding strategy for realizing the multiprotocol dynamic forwarding of flows. ESMD-Flow can reduce the network attack surface and improve the secure transmission capability of flows by implementing multipath routing and multi-protocol hybrid forwarding mechanism. The extensive simulations demonstrate that ESMD-Flow can significantly improve the average path reliability for routing and increase the difficulty of network eavesdropping while improving the network throughput and reducing the average packet delay. | Ziyong Li Yuxiang Hu Di Zhu JiangxingWu Yunjie Gu | 2022 | China Communications2022，19，1： | 1 |
