| 1 | QoS-Aware Dynamic Resource Management in Heterogeneous Mobile Cloud Computing Networks显示文摘In mobile cloud computing(MCC) systems,both the mobile access network and the cloud computing network are heterogeneous,implying the diverse configurations of hardware,software,architecture,resource,etc.In such heterogeneous mobile cloud(HMC) networks,both radio and cloud resources could become the system bottleneck,thus designing the schemes that separately and independently manage the resources may severely hinder the system performance.In this paper,we aim to design the network as the integration of the mobile access part and the cloud computing part,utilizing the inherent heterogeneity to meet the diverse quality of service(QoS)requirements of tenants.Furthermore,we propose a novel cross-network radio and cloud resource management scheme for HMC networks,which is QoS-aware,with the objective of maximizing the tenant revenue while satisfying the QoS requirements.The proposed scheme is formulated as a restless bandits problem,whose 'indexability' feature guarantees the low complexity with scalable and distributed characteristics.Extensive simulation results are presented to demonstrate the significant performance improvement of the proposed scheme compared to the existing ones. | SI Pengbo ZHANG Qian F.

| 13 | Carbon nanodots enhanced performance of Cs_(0.15)FA_(0.85)PbI_(3) perovskite solar cells显示文摘A high-quality hybrid Cs_(0.15)FA_(0.85)PbI_(3) thin film is deposited through doping of carbon nanodots(CNDs)into perovskite precursor solution.The corresponding inverted planar perovskite solar cells(PSCs)of ITO/PTAA/Cs_(0.15)FA_(0.85)PbI_(3)/PC_(61)BM/BCP/Ag exhibit an improvement in efficiency from 17.36%to 20.06%,which could be attributed to the passivation of the defects at the crystallized perovskite thin film and enhanced perovskite phase uniformity.The results of electron trap density indicate that the addition of CNDs significantly reduces the defects density at the perovskite thin film and the recombination of charge carriers in transport process is minimized.These results demonstrate that low-cost CNDs are effective additives for passivating defects,further reducing charge carrier recombination and improving device efficiency. | Yu Gao Wenzhan Xu Fang He Pengbo Nie Qingdan Yang Zhichun Si Hong Meng Guodan Wei | 2021 | Nano Research2021，14，7： | 0 |
| 14 | Construction of recombinant adeno-associated virus vector co-expressing hVEGF_(165) and hBMP_7 gene显示文摘Objective: To construct recombinant adeno-associated virus co-expressing human vascular epithelial growth factor 165(hVEGF165) and bone morphogenetic protein 7(hBMP7),measure the virus titer and verify the recombination. Methods:The AAV helper-free system was used as basis to generate recombinant AAV. The IRES sequence of plasmid pIRES was cut down and subcloned into ITR/MCS containing vector pAAV-MCS to construct recombinant plasmid pAAV-MCSa-IRES-MCSb. The hVEGF165 and hBMP7 gene was amplified by PCR and inserted into upstream MCSa and downstream MCSb respectively. Then,recombinant plasmid pAAV-hVEGF165-IRES-hBMP7,pAAV-RC and pHelper were co-transfected into AAV-293 cells to complete rAAV-hVEGF165-IRES-hBMP7 packaging. The GFP labeled rAAV-IRES-GFP was simultaneously packaged by using the parallel plasmid pAAV-IRES-hrGFP. The efficiency of AAV packaging was monitored under fluorescent microscope and recombinant viral particles were harvested from infected AAV-293 cells. The virus titer was measured by infecting AAV-HT1080 cells,and the recombinant AAV-hVEGF165-IRES-hBMP7 was verified by PCR of the exogenous interest genes. Results:Recombinant pAAV-hVEGF165-IRES-hBMP7 was verified by double digestion. GFP expression in AAV-293 could be observed under fluorescent microscope 72 h after transfection and the system provided a high packing ratio of 95%. The recombinant adeno-associated virus has a high titer of 5.5×1011vp/ml,and AAV-HT 1080 was infected at a ratio of 90%. The recombinant virus was confirmed by PCR of exogenous hBMP7 and hVEGF165 gene. Conclusion:Recombinant rAAV-hVEGF165-IRES-hBMP7 was successfully constructed with a high virus titer,which may offer foundation for in vitro and in vivo experiments of hVEGF165 and hBMP7 co-expression and provide a new method for gene therapy of bone regeneration. | Zhibin Shi Xianghui Huang Kunzheng Wang Xiaoqian Dang Pei Yang Pengbo Yu | 2008 | Journal of Nanjing Medical University2008，22，4： | 0 |
| 15 | Research on Measures for TBT of Pork Export显示文摘With the deepening of economic globalization and increasingly fierce competition of trade liberalization in WTO member countries,the effect of traditional trade protection measures is gradually weakening or even removed. In recent years,Technical Barriers to Trade( TBT)as a category of nontariff barriers to trade,are the widely divergent measures that countries use to regulate markets,protect their consumers,or preserve their natural resources( among other objectives),but they also can be used( or perceived by foreign countries) to discriminate against imports in order to protect domestic industries. These directly or indirectly lead to gradual rise of trade friction of China's pork export. This paper analyzed background and significance of measures for TBT of pork export,current situations of researches on TBT both at home and abroad,and came up with new ideas and viewpoints for further strengthening measures for TBT of pork export. | Hua YU Yubao YAN Pengbo CUI | 2014 | Asian Agricultural Research2014，6，11： | 0 |
| 16 | PIFs interact with SWI2/SNF2-related 1 complex subunit 6 to regulate H2A.Z deposition and photomorphogenesis in Arabidopsis显示文摘Light is an essential environmental signal perceived by a broad range of photoreceptors in plants. Among them, the red/far-red light receptor phytochromes function to promote photomorphogenesis, which is critical to the survival of seedlings after seeds germination. The basic-helix-loop-helix transcription factors phytochrome-interacting factors (PIFs) are the pivotal direct downstream components of phytochromes. H2A.Z is a highly conserved histone variant regulating gene transcription, and its incorporation into nucleosomes is catalyzed by SWI2/SNF2-related 1 complex, in which SWI2/SNF2-related 1 complex subunit 6 (SWC6) and actin-related protein 6 (ARP6) serve as core subunits. Here, we show that PIFs physically interact with SWC6 in vitro and in vivo, leading to the disassociation of HY5 from SWC6. SWC6 and ARP6 regulate hypocotyl elongation partly through PIFs in red light. PIFs and SWC6 coregulate the expression of auxin-responsive genes such as IAA6, IAA19, IAA20, and IAA29 and repress H2A.Z deposition at IAA6 and IAA19 in red light. Based on previous studies and our findings, we propose that PIFs inhibit photomorphogenesis, at least in part, through repression of H2A.Z deposition at auxin-responsive genes mediated by the interactions of PIFs with SWC6 and promotion of their expression in red light. | Huiru Chen Wanting Wang Xiao Chen Yake Niu Yuanyuan Qi Ze Yu Minyu Xiong Pengbo Xu Wenxiu Wang Tongtong Guo Hong-Quan Yang Zhilei Mao | 2023 | Journal of Genetics and Genomics2023，50，12： | 0 |
| 17 | Establishment of a recombinant adeno-associated virus expressing hVEGF_(165)显示文摘BACKGROUND: Because certain gene vectors could have deleterious effects in the central nervous system, the choice of a safe and effective vector system has become more important for gene therapy of nerve regeneration. OBJECTIVE: To construct a non-pathogenic, recombinant adeno-associated virus (AAV) simultaneously expressing human vascular endothelial growth factor 165 (hVEGF165) and green fluorescent protein (GFP). DESIGN, TIME AND SETTING: A randomized controlled experiment was performed at the Virology Laboratory of Shaanxi Provincial Center for Disease Control and Prevention between March and September 2007. MATERIALS: AAV helper-free system, AAV-293 packaging cell line, and AAV HT-1080 cells were purchased from Stratagene, USA. E. coli DH5α was a stocked strain from Centers for Disease Control and Prevention of Shaanxi, China. Plasmid pUC18-hHVEGF165 was a gift from Zhibin Shi. METHODS: The hVEGF165 gene was amplified by PCR from pUC18-hHVEGF165 and inserted into plasmid pAAV-IRES-hrGFP to construct recombinant plasmid pAAV-hVEGF165-IRES-hrGFP. Subsequently pAAV-hVEGF165-IRES-hrGFP, pAAV-RC (the rep/cap-gene containing plasmid), and pHelper were co-transfected into AAV-293 cells to complete rAAV-hVEGF165-IRES-hrGFP packaging through homologous recombination. The efficiency of AAV packaging was monitored under a fluorescent microscope, and the recombinant viral particles were harvested from infected AAV-293 cells, and further concentrated and purified. AAV HT-1080 cells were infected with the recombinant virus AAV-hVEGF165-IRES-hrGFP. MAIN OUTCOME MEASURES: Recombinant virus titer was measured by fluorescent cell counting, and infection efficiency was detected by Fluorescence Activated Cell Sorter (FACS) upon infecting AAV-HT1080 cells. The recombination with the exogenous gene was verified by PCR. RESULTS: The PCR amplified products were verified as hVEGF165 gene by DNA sequencing, and the recombinant pAAV-hVEGF165-IRES-GFP was confirmed by double digestion. The system provided a high packaging ratio of 95%, and the purified recombinant virus had a high titer of 5.5×1011 virus particles/mL. The AAV-HT1080 cells were infected at a ratio of 90.4%. The recombinant virus was confirmed by PCR to contain the exogenous hVEGF165 gene. CONCLUSION: The non-pathogenic rAAV-hVEGF165-GFP vector, carrying hVEGF165 and GFP reporter gene, was successfully constructed with a high titer and infection efficiency. | Xianghui Huang Zhibin Shi Xiaoqian Dang Chen Zhang Pengbo Yu Kunzheng Wang | 2008 | Neural Regeneration Research2008，3，6： | 0 |
| 18 | Error propagation determined iterative channel estimation with ICI mitigation for fast time-varying OFDM channels显示文摘The intersubcarrier interference(ICI) degrades the performance of the pilot-aided channel estimation in fast time-varying orthogonal frequency division multiplexing(OFDM) systems.To solve the error propagation in joint channel estimation and data detection due to this ICI,a scheme of error propagation determined iterative estimation is proposed,where in the first iteration,Kalman filter based on signal to interference and noise is designed with ICI transformed to be part of the noise,and for the later iterations,a determined iterative estimation algorithm obtains an optimal output from all iterations using the iterative updating strategy.Simulation results present the significant improvement in the performance of the proposed scheme in high-mobility situation in comparison with the existing ones. | 张杰 Yang Ruizhe Si Pengbo Zhang Yanhua Yu Richard | 2014 | High Technology Letters2014，20，4： | 0 |
| 19 | Lithium-Ion Charged Polymer Channels Flattening Lithium Metal Anode显示文摘The concentration difference in the near-surface region of lithium metal is the main cause of lithium dendrite growth.Resolving this issue will be key to achieving high-performance lithium metal batteries(LMBs).Herein,we construct a lithium nitrate(LiNO_(3))-implanted electroactiveβphase polyvinylidene fluoride-co-hexafluoropropylene(PVDF-HFP)crystalline polymorph layer(PHL).The electronegatively charged polymer chains attain lithium ions on the surface to form lithium-ion charged channels.These channels act as reservoirs to sustainably release Li ions to recompense the ionic flux of electrolytes,decreasing the growth of lithium dendrites.The stretched molecular channels can also accelerate the transport of Li ions.The combined effects enable a high Coulombic efficiency of 97.0%for 250 cycles in lithium(Li)||copper(Cu)cell and a stable symmetric plating/stripping behavior over 2000 h at 3 mA cm^(-2)with ultrahigh Li utilization of 50%.Furthermore,the full cell coupled with PHL-Cu@Li anode and Li Fe PO_(4) cathode exhibits long-term cycle stability with high-capacity retention of 95.9%after 900 cycles.Impressively,the full cell paired with LiNi_(0.87)Co_(0.1)Mn_(0.03)O_(2)maintains a discharge capacity of 170.0 mAh g^(-1)with a capacity retention of 84.3%after 100 cycles even under harsh condition of ultralow N/P ratio of 0.83.This facile strategy will widen the potential application of LiNO_(3)in ester-based electrolyte for practical high-voltage LMBs. | Haofan Duan Yu You Gang Wang Xiangze Ou Jin Wen Qiao Huang Pengbo Lyu Yaru Liang Qingyu Li Jianyu Huang Yun‑Xiao Wang Hua‑Kun Liu Shi Xue Dou Wei‑Hong Lai | 2024 | Nano-Micro Letters2024，16，4： | 0 |
