| 1 | Vehicle-to-Infrastructure Channel Characterization in Urban Environment at 28 GHz显示文摘Both ultra-reliable low latency and high-data-rate communications are required by connective vehicles. Millimeter wave(mm Wave) with large bandwidth is a key technology to support high-data-rate communications. In this paper, the 28 GHz wideband vehicle-to-infrastructure channel is characterized for the urban environment in a major street in Manhattan. The deployment of the transmitter and the receiver, as well as the traffic models, are selected by considering the recommendation by 3GPP TR 37.885. Ray tracing simulator with calibrated electromagnetic parameters is employed in this work to practically conduct intensive simulations. The 3D environment model is reconstructed from OpenStreetMap. The power delay profile, path loss, root-meansquare delay spread, K-factor and so on, are extracted from the calibrated simulation results. The evolution of the parameters, as well as their statistical properties, are analyzed and modeled. The work of this paper helps the researchers understand the propagation channel for designing mmWave technologies and communication system in a similar scenario. | Longhe Wang Bo Ai Danping He Ke Guan Jiayi Zhang Junhyeong Kim Zhangdui Zhong | 2019 | China Communications2019，16，2： | 3 |
| 2 | User Association and Wireless Backhaul Bandwidth Allocation for 5G Heterogeneous Networks in the Millimeter-Wave Band显示文摘The user association and wireless backhaul bandwidth allocation for a two-tier heterogeneous network(Het Net) in the millimeter wave(mm Wave) band is proposed in this article. The two-tier Het Net is built up with a macro base station(MBS) and several small cell SBSs, where the MBS is assumed to be equipped with large-scale antenna arrays but the SBSs only have single-antenna capability and they rely on the wireless link to the MBS for backhaul. The sum of logarithmic user rate, which is established according to the result of multi-user Multiple Input Multiple Output(MIMO) downlink employing Zero-Force Beamforming(ZFBF), is chosen as the network utility for the objective function. And a distributed optimization algorithm based on primal and dual decomposition is used to jointly optimize the user association variable xj,i and the wireless backhaul bandwidth factor β. Simulation results reveal that the distributed optimization algorithm jointly optimizing two variables outperforms the conventional SINR-based user association strategies. | zhenxiang su bo ai yichuan lin danping he ke guan ning wang guoyu ma li niu | 2018 | China Communications2018，15，4： | 2 |
| 3 | Geotectonic evolution of lunar LQ-4 region based on multisource data显示文摘The Sinus Iridum region, the first choice for China's 'Lunar Exploration Project' is located at the center of the lunar LQ-4 area and is the site of Chang'e-3(CE-3)'s soft landing. To make the scientific exploration of Chang'e-3 more targeted and scientific, and to obtain a better macro-level understanding of the geotectonic environment of the Sinus Iridum region, the tectonic elements in LQ-4 region have been studied and the typical structures were analyzed statistically using data from CE-1, Clementine, LRO and Lunar Prospector missions. Also, the mineral components and periods of mare basalt activities in the study area have been ascertained. The present study divides the tectonic units and establishes the major tectonic events and sequence of evolution in the study area based on morphology, mineral constituents,and tectonic element distribution. | Jianping Chen Yanbo Xu Xiang Wang Shujun He Danping Yan Shaofeng Liu Yongliao Zou Yongchun Zheng | 2014 | Geoscience Frontiers2014，5，2： | 1 |
| 4 | Minor change in the length of carbon chain has a great influence on the antitumor effect of paclitaxel-fatty alcohol prodrug nanoassemblies:Small roles,big impacts显示文摘Prodrug-based nanoassembly emerges as a hopeful way for the efficient delivery of antitumor drugs,with carrier-free structure and ultra-high drug loading.Carbon chains are widely used to design self-assembling prodrugs.The impacts of the length of carbon chains on the self-assembly stability,drug delivery efficiency and antitumor effect of prodrugs have not been fully elucidated.Here,three paclitaxel prodrugs were synthesized by conjugating paclitaxel with octanol(C_(8)),decanol(C_(10))or dodecanol(C_(12))through disulfide bond.The three prodrugs could form homogeneous nanoparticles,with over 50%drug loading and redox dual-responsivity.Interestingly,the length extension of carbon chains ameliorates the self-assembly and the colloidal stability of prodrugs,thus improving the drug delivery efficiency.The optimal paclitaxel-dodecanol prodrug nanoassemblies exhibit better antitumor efficacy than Taxol and Abraxane.These findings are meaningful for the rational design of advanced nanomedicines in cancer therapy. | Xin Wang Lingxiao Li Danping Wang Shiyi Zuo Tian Liu Fudan Dong Xuanbo Zhang Zhonggui He Bingjun Sun Jin Sun | 2022 | Nano Research2022，15，4： | 1 |
| 5 | Towards 6G: Paradigm of Realistic Terahertz Channel Modeling显示文摘Terahertz(THz)communications are envisioned as a key technology for the sixth-generation wireless communication system(6G).However,it is not practical to perform large-scale channel measurements with high degrees of freedom at THz frequency band.This makes empirical or stochastic modeling approaches relying on measurements no longer stand.In order to break through the bottleneck of scarce fulldimensional channel sounding measurements,this paper presents a novel paradigm for THz channel modeling towards 6G.With the core of high-performance ray tracing(RT),the presented paradigm requires merely quite limited channel sounding to calibrate the geometry and material electromagnetic(EM)properties of the three-dimensional(3D)environment model in the target scenarios.Then,through extensive RT simulations,the parameters extracted from RT simulations can be fed into either ray-based novel stochastic channel models or cluster-based standard channel model families.Verified by RT simulations,these models can generate realistic channels that are valuable for the design and evaluation of THz systems.Representing two ends of 6G THz use cases from microscopy to macroscopy,case studies are made for close-proximity communications,wireless connections on a desktop,and smart rail mobility,respectively.Last but not least,new concerns on channel modeling resulting from distinguishing features of THz wave are discussed regarding propagation,antenna array,and device aspects,respectively. | Ke Guan Haofan Yi Danping He Bo Ai Zhangdui Zhong | 2021 | China Communications2021，18，5： | 1 |

| 8 | A Ray Tracing and Joint Spectrum Based Clustering and Tracking Algorithm for Internet of Intelligent Vehicles显示文摘Driven by the rapid growth in information services provided by the Internet and the appearance of new multimedia applications,millimeter wave is foreseen as a key enabler towards the Internet of intelligent vehicles(IoIV)for urban traffic safety enhancement.In this regard,cluster-based channel modeling has become an important research topic in the realm of emergency communications.To fully understand the cluster-based channel model,a series of vehicle-to-infrastructure(V2I)channel simulations at 22.6 GHz are conducted by a three-dimensional ray tracing(RT)simulator.The clustering and tracking algorithm is proposed and analyzed from three aspects by the obtained simulation results.The multiple signal classification estimation spectrum is applied to restrain the influence of antenna sidelobes and identify targets at first.Based on the fundamentals,the clusters can be identified and subsequently tracked using the proposed approach.The impacts of antenna sidelobes,angle resolution of beam rotation,and non-line-of-sight propagation path on the performance of clustering and tracking are evaluated.The multi-component-level RT results are adopted as comparison benchmarks,which reflect the ground truth.This work aims to provide a full picture of the clustering characteristics for designing and analyzing emergency communication systems. | Luoyan Zhu Danping He Bo Ai Ke Guan Shuping Dang Junhyeong Kim Heesang Chung Zhangdui Zhong | 2020 | Journal of Communications and Information Networks2020，5，3： | 0 |
| 9 | The effect of lengths of branched-chain fatty alcohols on the efficacy and safety of docetaxel-prodrug nanoassemblies显示文摘The self-assembly prodrugs are usually consisted of drug modules,activation modules,and assembly modules.Keeping the balance between efficacy and safety by selecting suitable modules remains a challenge for developing prodrug nanoassemblies.This study designed four docetaxel(DTX)prodrugs using disulfide bonds as activation modules and different lengths of branched-chain fatty alcohols as assembly modules(C_(16),C_(18),C_(20),and C_(24)).The lengths of the assembly modules determined the self-assembly ability of prodrugs and affected the activation modules’sensitivity.The extension of the carbon chains improved the prodrugs’self-assembly ability and pharmacokinetic behavior while reducing the cytotoxicity and increased cumulative toxicity.The use of C_(20) can balance efficacy and safety.These results provide a great reference for the rational design of prodrug nanoassemblies. | Shuo Wang Tian Liu Yuetong Huang Chaoying Du Danping Wang Xiyan Wang Qingzhi Lv Zhonggui He Yinglei Zhai Bingjun Sun Jin Sun | 2024 | Acta Pharmaceutica Sinica B2024，14，3： | 0 |
