| 2 | Optimal Spectrum Sensing in Energy Harvesting Cognitive Radio Systems显示文摘In this paper,we consider a cognitive radio system with energy harvesting,in which the secondary user operates in a saving-sensing-transmitting(SST) fashion.We investigate the tradeoff between energy harvesting,channel sensing and data transmission and focus on the optimal SST structure to maximize the SU's expected achievable throughput.We consider imperfect knowledge of energy harvesting rate,which cannot be exactly known and only its statistical information is available.By formulating the problem of expected achievable throughput optimization as a mixed-integer non-linear programming one,we derive the optimal saveratio and number of sensed channels with indepth analysis.Simulation results show that the optimal SST structure outperforms random one and performance gain can be enhanced by increasing the SU's energy harvesting rate. | QU Zhaowei SONG Qizhu YIN Sixing | 2014 | China Communications2014，11，5： | 4 |

| 8 | Feedback LSTM Network Based on Attention for Image Description Generator显示文摘Images are complex multimedia data which contain rich semantic information.Most of current image description generator algorithms only generate plain description,with the lack of distinction between primary and secondary object,leading to insufficient high-level semantic and accuracy under public evaluation criteria.The major issue is the lack of effective network on high-level semantic sentences generation,which contains detailed description for motion and state of the principal object.To address the issue,this paper proposes the Attention-based Feedback Long Short-Term Memory Network(AFLN).Based on existing codec framework,there are two independent sub tasks in our method:attention-based feedback LSTM network during decoding and the Convolutional Block Attention Module(CBAM)in the coding phase.First,we propose an attentionbased network to feedback the features corresponding to the generated word from the previous LSTM decoding unit.We implement feedback guidance through the related field mapping algorithm,which quantifies the correlation between previous word and latter word,so that the main object can be tracked with highlighted detailed description.Second,we exploit the attention idea and apply a lightweight and general module called CBAM after the last layer of VGG 16 pretraining network,which can enhance the expression of image coding features by combining channel and spatial dimension attention maps with negligible overheads.Extensive experiments on COCO dataset validate the superiority of our network over the state-of-the-art algorithms.Both scores and actual effects are proved.The BLEU 4 score increases from 0.291 to 0.301 while the CIDEr score rising from 0.912 to 0.952. | Zhaowei Qu Bingyu Cao Xiaoru Wang Fu Li Peirong Xu Luhan Zhang | 2019 | Computers, Materials & Continua2019，，5： | 1 |

| 10 | An intelligent near-infrared light activatable nanosystem for accurate regulation of zinc signaling in living cells显示文摘Accurate regulation of cellular zinc signaling is imperative to decipher underlyingzinc functions and develop new therapeutic agents. However, the ability tomodulate zinc in a spatiotemporal manner remains elusive. We herein report anintelligent spiropyran-upconversion (SP-UCNPs) based nanosystem that enablesnear-infrared (NIR) light-controlled zinc release at precise times and locations.The magnitude of zinc release can be simply manipulated by varying the durationof NIR irradiation. Moreover, the utilization of NIR light not only showed littledamage to cells but also significantly improved penetration depth. By evaluatingactivity of a model protein, phosphatase 2A, we further validated zinc signalingactivation. Importantly, our strategy may be broadly applicable to other types ofmetal ions, like the ubiquitous second messenger calcium. More importantly, ourstrategy can potentially enable the precise control of specific signaling pathways ofmetal ions while minimizing cellular damage, facilitating the advanced manipulationof cellular dynamics. | Wei Li Zhen Liu Zhaowei Chen Lihua Kang Yijia Guan Jinsong Ren Xiaogang Qu | 2017 | Nano Research2017，10，9： | 0 |
| 11 | Nucleation growth quenching for superior cluster catalysts显示文摘Cluster catalysts are rapidly growing into an important sub-field in heterogeneous catalysis,owing to their distinct geometric structure,neighboring metal sites,and unique electronic structure.Although the thermodynamics and kinetics of the formation of nanoparticles have been largely investigated,the precise synthesis of clusters in wet chemical methods still faces great challenges.In the study,a quenching strategy of asymmetric temperature in solution for the rapid generation of vacancy-defect rich clusters is reported.The quenching process can be used to synthesize multitudinous metal compound clusters,including metal oxides,fluorides,oxygen-sulfur compounds,and tungstate.For oxygen evolution reaction(OER),IrO_(2)clusters with abundant oxygen vacancies were obtained and uniformly dispersed in the solution.Compared to commercial IrO_(2),the prepared IrO_(2)cluster can be directly loaded on carbon paper and used as binder-free electrodes,which exhibit higher OER activity and long-term operational stability in alkaline electrolytes.The quenching strategy provides a simple and efficient method for the synthesis of clusters,which has tremendous potential for industrial-scale preparation and application,especially can be further applied to flow electrochemical generators. | Ruyue Wang Feng Cheng Yonggang Wang Dongyu Fan Bohan Deng Yuanzheng Long Haolin Tang Kai Huang Zhaowei Qu Ming Lei Binghui Ge Hui Wu | 2022 | Nano Research2022，15，9： | 0 |
| 12 | Predictive Spectrum Sensing Strategy Based on Reinforcement Learning显示文摘In this paper,we consider a cognitive radio(CR) system with a single secondary user(SU) and multiple licensed channels.The SU requests a fixed number of licensed channels and must sense the licensed channels one by one before transmission.By leveraging prediction based on correlation between the licensed channels,we propose a novel spectrum sensing strategy,to decide which channel is the best choice to sense in order to reduce the sensing time overhead and further improve the SU's achievable throughput.Since the correlation coefficients between the licensed channels cannot be exactly known in advance,the spectrum sensing strategy is designed based on the model-free reinforcement learning(RL).The experimental results show that the proposed spectrum sensing strategy based on reinforcement learning converges and outperforms random sensing strategy in terms of long-term statistics. | QU Zhaowei CUI Rong SONG Qizhu YIN Sixing | 2014 | China Communications2014，11，10： | 0 |
| 13 | Optimization of Crosswalk Width Based on Bi-Directional Pedestrian Crossing Time at Signalized Intersections显示文摘The effects of the interactions between bi-directional pedestrians on the crossing time and the crosswalk width are studied. Firstly,the crossing process of bi-directional pedestrians is analyzed.The total crosswalk time is divided into a discharge time and a crossing time. The interactions between bi-directional pedestrians are quantified with the drag force theory. Then,a model is developed to study the crossing time based on the kinetic energy theory and momentum theory. Subsequently,the related parameters of the proposed model are calibrated with observed information. The relationships among crosswalk width,signal time,pedestrian volume and level of service are simulated with the proposed model. The results are verified and compared with other models. The proposed model has an absolute value of relative error of 9. 38%,which is smaller than that of the Alhajyaseen model( 15. 26%) and Highway Capacity Manual( HCM) model( 12. 42%). Finally,suggested crosswalk widths at different conditions are successfully estimated with the proposed crossing time model. | Ningbo Cao Yongheng Chen Zhaowei Qu Liying Zhao Yanfei Li Qiujie Yang | 2018 | Journal of Beijing Institute of Technology2018，27，2： | 0 |
| 14 | DESIGN OF BEAM-WAVE INTERACTION BASED ON HIGH EFFICIENCY OF A HIGH-POWER BROADBAND KLYSTRON显示文摘The paper mainly presents the design of beam-wave interaction of a C-band high-peakpower high-efficiency broadband klystron.The beam-wave interaction section is designed based on considerations of efficiency and bandwidth synthetically.As a part of beam-wave interaction section,buncher section is simulated by Particle-In-Cell(PIC) code to observe the bunching process of electron beam to achieve high conversion efficiency of electron beam and RF field.When it comes to the other part,output circuit is designed as a three-section filter by an output cavity loaded with Chebyshev filter,and the cold test results are given.The beam-wave interaction is simulated by EGUN code and Arsenal-MSU code respectively.The simulated results indicated that,the existence of power dips in the operating bandwidth is verified by Arsenal-MSU code,comparing proper results by EGUN code.Then,the method that design parameters are not adjusted except parameters of buncher cavities to remove potential power dips is described.What is more,the simulated results of electron optics system are given by EGUN code and Arsenal-MSU code respectively.The further hot test results of klystron prove that the whole design of beam-wave interaction is effective. | Qu Zhaowei Zhang Zhaochuan Liu Pukun Zhang Rui Fan Junjie | 2014 | Journal of Electronics(China)2014，31，2： | 0 |
