| 1 | On the infimum problem of Hilbert space effects显示文摘The quantum effects for a physical system can be described by the set ε(H) of positive operators on a complex Hilbert space Hthat are bounded above by the identity operator Ⅰ. The infimum problem of Hilbert space effects is to find under what condition the infimum A∧B exists for two quantum effects A and B ∈ε(H). The problem has been studied in different contexts by R. Kadison, S. Gudder, M. Moreland, and T. Ando. In this note, using the method of the spectral theory of operators, we give a complete answer of the infimum problem. The characterizations of the existence of infimum A ∧ B for two effects A, B ∈ε(H) are established. | DU Hongke DENG Chunyuan LI Qihui | 2006 | Science China Mathematics2006，49，4： | 16 |
| 2 | Superplastic Solid-Phase Welding of 40 Cr-T10A Steel显示文摘The microstructure of 40Cr and T10A steel sample and its surface to be welded is ultra-fined through salt-bath cyclic quenching and high frequency hardening, then the surface is cleaned. Under non-vacuum and no shielded gas, the welding parameter of isothermal superplastic solidphase welding and the effect of surface microstructure prior to pressure welding on the quality of joint are studied. At the temperature of 730~750°C and at initial strain rate of (2~4) × 10-4 s-1,the strength of the joint is up to or close to that of 40Cr base metal in 3~5 min pressure welding. | Keke ZHANG Yunlin YANG Changsheng WANG Hongke LI Jin XUE | 2001 | Journal of Materials Science & Technology2001，17，1： | 10 |
| 3 | A Survey on Smart Collaborative Identifier Networks显示文摘The current Internet architecture was designed on the basis of a triple bindings model, which could meet the needs of the early Internet. However, with the tremendous growth of the Internet and the continuous innovations of applications, the triple bindings(namely, control/data binding, resource/location binding and user/network binding) have given rise to many problems for the Internet, such as scalability, mobility, and security. In order to solve these problems, many network techniques have been developed. Besides, novel future Internet architectures including Information-Centric Networks and Software-Defined Networks have emerged. However, these architectures only partially decouple the triple bindings. To completely separate the triple bindings, Smart Collaborative Identifier Networks(SINET) is proposed. There have been many research efforts on SINET, which built the foundation of SINET being a promising future Internet. In this paper, we comprehensively introduce SINET and these related research works. We start by introducing the motivation for SINET, explain its fundamental concepts and how it can make a difference. Next, we present in details the design principles of every layer in SINET, explaining how it can decouple the triple bindings and solve the problems of the current Internet. Finally, we discuss the state-of-theart challenges in SINET. We investigate the ongoing research works and commercial products in SINET, with aspects such as scalability, mobility, security and reliability. | Haifeng Li Hongke Zhang | 2018 | China Communications2018，15，3： | 3 |

| 5 | Main Detrainment Height of Deep Convection Systems over the Tibetan Plateau and Its Southern Slope显示文摘Deep convection systems (DCSs) can rapidly lift water vapor and other pollutants from the lower troposphere to the upper troposphere and lower stratosphere. The main detrainment height determines the level to which the air parcel is lifted. We analyzed the main detrainment height over the Tibetan Plateau and its southern slope based on the CloudSat Cloud Profiling Radar 2B_GEOPROF dataset and the Aura Microwave Limb Sounder Level 2 cloud ice product onboard the Atrain constellation of Earth-observing satellites. It was found that the DCSs over the Tibetan Plateau and its southern slope have a higher main detrainment height (about 10-16 km) than other regions in the same latitude. The mean main detrainment heights are 12.9 and 13.3 km over the Tibetan Plateau and its southern slope, respectively. The cloud ice water path decreases by 16.8% after excluding the influences of DCSs, and the height with the maximum increase in cloud ice water content is located at 178 hPa (about 13 km). The main detrainment height and outflow horizontal range are higher and larger over the central and eastern Tibetan Plateau, the west of the southern slope, and the southeastern edge of the Tibetan Plateau than that over the northwestern Tibetan Plateau. The main detrainment height and outflow horizontal range are lower and broader at nighttime than during daytime. | Quanliang CHEN Guolu GAO Yang LI Hongke CAI Xin ZHOU Zhenglin WANG | 2019 | Advances in Atmospheric Sciences2019，36，10： | 1 |
| 6 | The first two leading modes of the tropical Pacific and their linkage without global warming显示文摘A discrepancy remains in the first two leading empirical orthogonal function(EOF) modes of the tropical Pacific sea surface temperature anomaly(SSTA) based on observations since the 1980s. The EOF1 mode, representing the El Ni?o-Southern Oscillation(ENSO), is a robust result. However, the EOF2 features either El Ni?o Modoki(EM) or ENSO evolution during different periods, which is probably associated with the impacts of global warming. The underlying question is what the EOF2 mode of the tropical Pacific would be without global warming. Using the CMIP5 preindustrial scenario to exclude the influence of global warming, we find that the EOF1 mode of the tropical Pacific SSTA represents ENSO and that the EOF2 mode is not EM. According to the lead–lag correlation between the ENSO and EOF2 modes, the linkage between these two modes is as follows: …El Ni?o → EOF2 → La Ni?a →–EOF2 → El Ni?o…. By analyzing the evolution of sea surface temperature, surface wind, and subsurface ocean temperature anomalies, we find the mechanism linking the ENSO and EOF2 modes is the air–sea interaction associated with the ENSO cycle. This result suggests that the EOF2 mode represents an aspect of ENSO evolution under preindustrial conditions. Therefore, this study further indicates that the EM is probably due to the influence of global warming. | Yang Li QuanLiang Chen XiaoRan Liu Nan Xing ZhiGang Cheng HongKe Cai Xin Zhou Dong Chen XiaoFei Wu MingGang Li | 2019 | Earth and Planetary Physics2019，3，2： | 1 |

| 10 | Additive Manufacturing of Large-scale Metal Mesh with Core-shell Composite Structure for Transparent Electromagnetic Shielding/glass Heater显示文摘Transparent electromagnetic(EM)shielding glass with a metal mesh has significant potential for application in different fields of EM radiation and anti-EM interference light-transmitting observation windows.In particular,a transparent EM-shielding glass with a large-aspect-ratio metal mesh can effectively alleviate the contradictory problems of shielding effectiveness and light-transmission performance constraints.However,the fabrication of high-aspect-ratio metal meshes on glass substrates has problems such as high cost,complex processes,low efficiency,small area,and easy damage issues,which limit their application in the field of high-performance,transparent EM-shielding glass.Therefore,this paper proposes a composite additive manufacturing process based on electric-field-driven microjet 3D printing and electroplating.By fabricating metal meshes with an Ag-Cu core-shell structure on a glass substrate,EM-shielding glass with high shielding efficiency and light transmission can be manufactured without increasing the aspect ratio of the metal meshes.The prepared Ag-Cu composite metal mesh has excellent optoelectronic properties(period 250��m,line width 10��m,90.1%transmission at 550 nm visible light,square resistance 0.21Ω/sq),efficient electrothermal effect(3 V DC voltage can reach 189°C steady-state temperature),stable EM-shielding effectiveness(average shielding effectiveness 23 dB at X-band),and acceptable mechanical and environmental stability(less than 3%change in square resistance after 150-times adhesion test and less than 6%and 0.6%change in resistance after 72 h in acid and alkali environments,respectively).This method provides a new solution for the mass production of high-performance large-area transparent electric heating/EM-shielding glass. | Yuping Tai Junyi Zhou Xiaoyang Zhu Houchao Zhang Hongke Li Zhenghao Li Rui Wang Fan Zhang Guangming Zhang Chaohong Liu Hongbo Lan | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，3： | 0 |

| 12 | Distributed rate allocation for elastic flows in concurrent multipath transfer显示文摘Concurrent multipath transfer(CMT) using stream control transmission protocol(SCTP) multihoming has become an appealing option to increase the throughput and improve the performance of increasingly bandwidth-hungry applications.To investigate the rate allocation for applications in CMT,this paper analyzes the capacities of paths shared by competing sources,then proposes the rate allocation model for elastic flows based on the framework of network utility maximization(NUM).In order to obtain the global optimum of the model,a distributed algorithm is presented which depends only on local available information.Simulation results confirm that the proposed algorithm can achieve the global optimum within reasonable convergence times. | Shiyong Li Yajuan Qin Hongke Zhang | 2010 | Journal of Systems Engineering and Electronics2010，21，5： | 0 |
| 13 | A Novel Location Management Scheme based on DNS in Proxy Mobile IPv6显示文摘Proxy Mobile IPv6 (PMIPv6) is designed to provide a network-based localized mobility management protocol, but it does not handle the global mobility of hosts. In this paper, we propose a location management scheme based on Domain Name System (DNS) for PMIPv6 which can support global mobility by using DNS as a location manager. In addition, to support large numbers of mobile terminals and enhance network scalability a paging extension scheme is introduced to PMIPv6. To evaluate the proposed location management scheme, we establish an analytical model, formulate the location update cost and the paging cost, and analyze the influence of the different factors on the total signaling cost. The performance results show that our proposed scheme outperforms the basic PMIPv6 under various parameters in terms of reducing the signaling overhead and the proposed scheme reduces signaling overhead compared to the basic PMIPv6. | Qiu Feng Li Xiaoqian Su Wei Zhang Hongke | 2010 | China Communications2010，7，3： | 0 |
| 14 | Recent advances in nanofiber-based flexible transparent electrodes显示文摘Flexible and stretchable transparent electrodes are widely used in smart display,energy,wearable devices and other fields.Due to the limitations of flexibility and stretchability of indium tin oxide electrodes,alternative electrodes have appeared,such as metal films,metal nanowires,and conductive meshes.However,few of the above electrodes can simultaneously have excellent flexibility,stretchability,and optoelectronic properties.Nanofiber(NF),a continuous ultra-long one-dimensional conductive material,is considered to be one of the ideal materials for high-performance transparent electrodes with excellent properties due to its unique structure.This paper summarizes the important research progress of NF flexible transparent electrodes(FTEs)in recent years from the aspects of NF electrode materials,preparation technology and application.First,the unique advantages and limitations of various NF materials are systematically discussed.Then,we summarize the preparation technology of various advanced NF FTEs,and point out the future development trend.We also discuss the application of NFs in solar cells,supercapacitors,electric heating equipments,sensors,etc,and analyze its development potential in flexible electronic equipment,as well as problems that need to be solved.Finally,the challenges and future development trends are proposed in the wide application of NF FTEs in the field of flexible optoelectronics. | Houchao Zhang Xiaoyang Zhu Yuping Tai Junyi Zhou Hongke Li Zhenghao Li Rui Wang Jinbao Zhang Youchao Zhang Wensong Ge Fan Zhang Luanfa Sun Guangming Zhang Hongbo Lan | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
| 15 | A Large-Scale NFV-Based Emulation Platform for Smart Identifier Network显示文摘Network emulation is significant because of its ability to study network architecture running on real operating system and thewhole protocol stack. However, conservatively allocating a physical network equipment for a corresponding emulation network iscostly, scale-limited and rigid. In this paper, based on network function virtualization(NFV), we present a large-scale emulationplatform for the Smart Identifier Network(SINET). We pool and virtualize all hardware resources by lightweight virtualization technology. Controllers and orchestrators are designed to manage emulation and collect monitored SINET emulation results. The controllers are used to implement dynamically synchronously management for large-scale emulation network and link characteristics.The orchestrators are utilized to achieve overload avoidance and green computing with the Xiao's dynamic resource allocation algorithm. We implement flexibly programmable and dynamically configurable emulation. | LI Haifeng LI Taixin ZHANG Hongke | 2017 | ZTE Communications2017，15，3： | 0 |
| 16 | Monte Carlo and phantom study in the brain edema models显示文摘Because the brain edema has a crucial impact on morbidity and mortality,it is important to develop a noninvasive method to monitor the process of the brain edema effectively.When the brain edema occurs,the optical properties of the brain will change.The goal of this study is to access the feasibility and reliability of using noninvasive near-infrared spectroscopy(NIRS)monitoring method to measure the brain edema.Specifically,three models,including the water content changes in the cerebrospinal fuid(CSF),gray matter and white matter,were explored.Moreover,these models were numerically simulated by the Monte Carlo studies.Then,the phantom experiments were performed to investigate the light intensity which was measured at different detecting radius on the tissue surface.The results indicated that the light intensity correlated well with the conditions of the brain edema and the detecting radius.Briefly,at the detect ing radius of 3.0 cm and 4.0 cm,the light intensity has a high response to the change of tissue parameters and optical properties.Thus,it is possible to monitor the brain edema noninvasively by NIRS method and the light intensity is a reliable and simple parameter to assess the brain edema. | Yubing Liu Hongke Wang Yangyang Liu Weitao Li Zhiyu Qian | 2017 | Journal of Innovative Optical Health Sciences2017，，3： | 0 |
| 17 | Network layered priority mapping theory显示文摘In the early days of the Internet layered design,the information between layers did not exchange in large amount frequently.With the rapid growth of the Internet,the emergence of many technologies such as service data partition,multi-connection and multi-path has made it possible to frequently exchange complex information between layers.With regard to these changes,this paper introduces 'network layered priority mapping(NLPM)' for future Internet development.The NLPM aims to maximize the satisfaction of the Internet users.The NLPM is designed to differentiate priority of the information on different layers and integrate the information using priority mapping.With NLPM,network services can be delivered more efficiently;network utilization such as the utilization of connection,path and channel can also be improved.Model analysis,NS simulation and prototype implementation have proved the efficiency of NLPM. | YANG Dong ZHANG HongKe SONG Fei LI ShiYong | 2010 | Science China(Information Sciences)2010，53，9： | 0 |

| 19 | The Performance Analysis of the THMLD-based Mobile Multicast Method显示文摘Mobile multicast is important for the emerging applications such as mobile video or audio conference and mobile IPTV.Some mobile multicast schemes have been proposed in the past few years, but most of them study the reconstruc-tion of multicast delivery tree, and few consider the group membership management for mobile sub-scribers.In this paper, we propose a new mobile multicast method based on the Two-Hop Multicast Listener Discovery(THMLD) protocol which pro-vides the mobile multicast membership manage-ment function by forwarding the traditional MLD messages to its neighboring subnets.To evaluate its performance, we analyze the THMLD and set up the simulation platform to compare it with the several traditional mobile multicast methods.The results show that THMLD can reduce the multicast join time, and the THMLD-based mobile multicast method can reduce the multicast join delay at a cost of increasing additional multicast maintenance cost. | Guan Jianfeng Zhou Huachun Li Xin Zhang Hongke | 2009 | China Communications2009，6，4： | 0 |
| 20 | The tropical Pacific cold tongue mode and its associated main ocean dynamical process in CMIP5 models显示文摘The cold tongue mode(CTM),which represents the out-of-phase relationship in sea surface temperature anomaly(SSTA)variability between the Pacific cold tongue region and elsewhere in the tropical Pacific,shows a long-term cooling trend in the eastern equatorial Pacific.In this study,we investigate how well the CTM is reproduced in historical simulations generated by the 20 models considered in Phase 5 of the Coupled Model Intercomparison Project(CMIP5).Qualitatively,all 20 models roughly capture the cooling SSTA associated with the CTM.However,a quantitative assessment(i.e.,Taylor diagrams and the ratio of the trend between the simulations and observations)shows that only five of these 20 models(i.e.,CESM1-CAM5,CMCC-CM,FGOALS-g2,IPSL-CM5B-LR,and NorESM1-M)can reproduce with useful accuracy the spatial pattern and long-term trend of the CTM.We find that these five models generally simulate the main ocean dynamical process associated with the CTM.That is,these models adequately capture the long-term cooling trend in the vertical advection of the anomalous temperature by the mean upwelling.We conclude that the performance of these CMIP5 models,with respect to simulations of the long-term cooling trend associated with the vertical advection,and the related long-term decreasing trend of the vertical gradient of the oceanic temperature anomaly,can play an important role in successful reproduction of the CTM. | Yang Li QuanLiang Chen JianPing Li WenJun Zhang MinHong Song Wei Hua HongKe Cai XiaoFei Wu | 2019 | Earth and Planetary Physics2019，3，5： | 0 |
