| 1 | Role,path,and vision of“5G+BDS/GNSS”显示文摘Communication,positioning,navigation,and decision-making abilities have evolved into Positioning,Navigation,and Timing(PNT)intelligence during the long process of human migration and hence promoted human evolution.This article defines intelligence and smartness from the perspective of biological intelligence.New requirements as a result of the development of communication,navigation,time service,and decision making are identified in this study.The article points out that there are many radio PNT service methods,such as 5G,the new-generation high-speed communication networks and the low-latency and ubiquitous mobile communication networks as well as Global Navigation Satellite System(GNSS),but the integrated application is especially important in providing technical support for the adjustment and control of the physical world by intelligent sensing,cognition,decision-making,and precise coordination.The fusion of 5G and GNSS[including BeiDou Navigation Satellite System(BDS)]information with the corresponding equipment can be embedded into a machine to make it intelligent.Furthermore,the fused information of 5G and GNSS together with the environment information may extend human perception and physical world control ability in terms of time and space scale.It will help to develop critical information infrastructure in the age of intelligence,which will also extend the definition of artificial intelligence.Additionally,the“5G+BDS/GNSS”fusion path is analyzed explicitly herein in terms of realization methods,information processing,and new application services.On the whole,the application of“5G+BDS/GNSS+satellite-based communication”as a critical infrastructure for land,sea,air,space and network spatiotemporal control rights is proposed. | Jingnan Liu Kefu Gao Wenfei Guo Jingsong Cui Chi Guo | 2020 | Satellite Navigation2020，1，1： | 2 |
| 2 | Hidden Process Offline Forensic Based on Memory Analysis in Windows显示文摘Malicious software programs usually bypass the detection of anti-virus software by hiding themselves among apparently legitimate programs.In this work,we propose Windows Virtual Machine Introspection(WVMI)to accurately detect those hidden processes by analyzing memory data.WVMI dumps in-memory data of the target Windows operating systems from hypervisor and retrieves EPROCESS structures’address of process linked list first,and then generates Data Type Confidence Table(DTCT).Next,it traverses the memory and identifies the similarities between the nodes in process linked list and the corresponding segments in the memory by utilizing DTCT.Finally,it locates the segments of Windows’EPROCESS and identifies the hidden processes by further comparison.Through extensive experiments,our experiment shows that the WVMI detects the hidden process with high identification rate,and it is independent of different versions of Windows operating system. | CUI Jingsong ZHANG Heng QI Jing PENG Rong ZHANG Manli | 2017 | Wuhan University Journal of Natural Sciences2017，22，4： | 1 |
| 3 | Nanomechanics of individual amyloid fibrils using atomic force microscopy显示文摘Compression elasticity of glucagon amyloid fibrils in the transverse direction was investigated by a nanoindentation approach based on atomic force microscopy (AFM).With force-volume mapping, we obtained the correlations between radially applied force and compression of amyloid fibrils, from which the radial compressive elasticity can be deduced.The estimated elastic modulus at three typical locations of fibrils varied from (0.72±0.80) GPa to (1.26±0.62) GPa under small external forces, imply-ing the structural heterogeneity of different fibrils. | ZHOU XingFei CUI ChengYi ZHANG JinHai LIU JianHua LIU JingSong | 2010 | Chinese Science Bulletin2010，55，16： | 1 |
| 4 | A Less Resource-Consumed Security Architecture on Cloud Platform显示文摘Traditional security framework in cloud platform usually brings self-vulnerability and considerable additional resource consumption. To solve these problems, we propose an external processes monitoring architecture for current popular cloud platform Open Stack with kernel-based virtual machine(KVM). With this architecture, we can monitor all active processes in online virtual machine(VMs) and scan them for their potential maliciousness in OpenS tack with no agent, and can also detect hidden processes in offline VMs' memory snapshots and notice the user to decide whether to kill them when VMs become active. Analysis and experimental results show that our architecture is able to reduce consumption of CPU, memory and bandwidth in cloud platform and can detect viruses and hidden processes effectively in VMs. | CUI Jingsong LIAO Kun TIAN Changyou PENG Rong WU Xun | 2016 | Wuhan University Journal of Natural Sciences2016，21，5： | 1 |

| 6 | A multiphoton ionization study of acetone using time-of-flight mass spectrometry显示文摘The 3p Rydberg states of acetone and photodissociation of the acetone cation were studied using time-of-flight(TOF)mass spectrometry.The 3p Rydberg state spectroscopy of acetone was investigated with linearly polarized two-photon resonance enhanced multiphoton ionization(REMPI)from 320 to 337 nm.Several new transition bands were observed in the spectra.In addition to the CH3COCH3 + ion,CH3CO + and CH3 + fragments were observed.The laser power dependences suggest that the CH3COCH3 +,CH3CO + and CH3 + ions are produced in three-,four-,and four-photon processes,respectively.Production of CH3CO + and CH3 + involves excitation of the ground state acetone cation by an additional photon and subsequent decomposition of the excited acetone ion.The average translational energies of CH3CO + and CH3 + from dissociation in CH3COCH3 +(X)+hv→CH3CO + +CH3 and CH3COCH3 +(X)+hv→CH3 + +CH3CO,respectively,were derived from the ion TOF peak profiles. | ZHENG XianFeng WU HongXia SONG Yu WU JingZe ZHANG JingSong CUI ZhiFeng | 2010 | Chinese Science Bulletin2010，55，27： | 0 |
