| 3 | Experimental investigation of boundary layer transition over a delta wing at Mach number 6显示文摘An experimental study on the boundary layer transition over a delta wing was carried out at Mach number 6 in a quiet wind tunnel.The Nano-tracer-based Planar Laser Scattering(NPLS)and Temperature-Sensitive Paints(TSP)techniques were used to measure the fine flow field structure and the wall Stanton number of the delta wing.The influence of factors such as the angle of attack and the Reynolds number was studied.The following results were obtained.The boundary layer transition between the leading edge and the centerline was dominated by the crossflow instability.At the location of the initial appearance of the traveling crossflow waves,the Stanton number began to rise.The Stanton number reached a maximum when the crossflow waves were broken up to turbulence.Increasing the angle of attack increased the spanwise pressure gradient at the windward side of the delta wing,thereby increasing the crossflow instability and advancing the boundary layer transition front.However,increasing the angle of attack caused the transition front to move backward at the leeward side.In addition,the sensitivity of the boundary layer transition to the Reynolds number varied with the angle of attack and the region. | Haibo NIU Shihe YI Xiaolin LIU Xiaoge LU Dundian GANG | 2020 | Chinese Journal of Aeronautics2020，33，7： | 9 |
| 4 | Improved Algorithms for Removing Isolated Non-Meteorological Echoes and Ground Clutters in CINRAD显示文摘Using China New Generation Weather Radar(CINRAD) level-II data, the original algorithms for removing isolated non-meteorological echoes and ground clutters in radar data, which have been applied to Weather Surveillance Radar-1988 Doppler(WSR-88 D) in the USA and Severe Weather Automatic Nowcast(SWAN) system in China, are modified and improved. To remove isolated non-meteorological echoes, the new algorithm introduces a constraint parameter(Po) to distinguish whether a window of 5 × 5 points is isolated as external echoes. A statistical analysis of150 radar scans(5 cases, with each case comprising 30 scans) under three different echo types(small-scale convection, typhoon, and large-scale synoptic system) shows that the constraint parameter Po ≤ 0.167 is suitable for removing isolated non-meteorological echoes while preserving the edge of meteorological echoes. A new parameter, NDZ,which promotes the ability of the algorithm to identify the ground clutters appearing at two adjacent elevation angles,is constructed based on the vertical continuity of reflectivity. These improved algorithms are tested for four cases(three cases of isolated non-meteorological echoes and one case of ground clutters). Based on the statistics of 232 volume scans of radar data(on a temporal resolution of 1 h) measured at Nanchang station from 0000 UTC 5 to 1600 UTC 14 March 2015, it is found that the improved algorithms not only eliminate most(over 95% under clear-sky conditions) of the isolated non-meteorological echoes and ground clutters(including those appearing at two adjacent elevation angles), but also well preserve the structure of meteorological echoes(storms). | Haibo ZOU Shuwen ZHANG Xudong LIANG Xueting YI | 2018 | Journal of Meteorological Research2018，32，4： | 6 |

| 6 | Energy Optimization for Cellular-Connected Multi-UAV Mobile Edge Computing Systems with Multi-Access Schemes显示文摘In this paper,a cellular-connected unmanned aerial vehicle(UAV)mobile edge computing system is studied where several UAVs are associated to a terrestrial base station(TBS)for computation offloading.To compute the large amount of data bits,a part of computation task is migrated to TBS and the other part is locally handled at UAVs.Our goal is to minimize the total energy consumption of all UAVs by jointly adjusting the bit allocation,power allocation,resource partitioning as well as UAV trajectory under TBS’s energy budget.For deeply comprehending the impact of multi-UAV access strategy on the system performance,four access schemes in the uplink transmission is considered,i.e.,time division multiple access,orthogonal frequency division multiple access,one-by-one access and non-orthogonal multiple access.The involved problems under different access schemes are all formulated in non-convex forms,which are difficult to be tackled optimally.To solve this class of problem,the successive convex approximation technique is employed to obtain the suboptimal solutions.The numerical results show that the proposed scheme save significant energy consumption compared with the benchmark schemes. | Meng Hua Yongming Huang Yi Wang Qingqing Wu Haibo Dai Lyuxi Yang | 2018 | Journal of Communications and Information Networks2018，3，4： | 6 |
| 7 | Virtual reality-based rehabilitation in patients following total knee arthroplasty:a systematic review and meta-analysis of randomized controlled trials显示文摘Background:Physical therapy is regarded as an essential aspect in achieving optimal outcomes following total knee arthroplasty(TKA).The coronavirus disease 2019(COVID-19)pandemic has made face-to-face rehabilitation inaccessible.Virtual reality(VR)is increasingly regarded as a potentially effective option for offering health care interventions.This systematic review and meta-analysis investigate VR-based rehabilitation's effectiveness on outcomes following TKA.Methods:From inception to May 22,2021,PubMed/Medline,Embase,Web of Science,the Cochrane Central Register of Controlled Trials,Scopus,PsycINFO,Physiotherapy Evidence Database,China National Knowledge Infrastructure,and Wanfang were comprehensively searched to identify randomized controlled trials(RCTs)evaluating the effect of VR-based rehabilitation on patients following TKA according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane Handbook for Systematic Reviews of Interventions.Results:Eight studies were included in the systematic review,and seven studies were included in the meta-analysis.VR-based rehabilitation significantly improved visual analog scale(VAS)scores within 1 month(standardized mean difference[SMD]:−0.44;95%confidence interval[CI]:−0.79 to−0.08,P=0.02),the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)within 1 month(SMD:−0.71;95%CI:−1.03 to−0.40,P<0.01),and the Hospital for Special Surgery Knee Score(HSS)within 1 month and between 2 months and 3 months(MD:7.62;95%CI:5.77 to 9.47,P<0.01;MD:10.15;95%CI:8.03 to 12.27,P<0.01;respectively)following TKA compared to conventional rehabilitation.No significant difference was found in terms of the Timed Up and Go(TUG)test.Conclusions:VR-based rehabilitation improved pain and function but not postural control following TKA compared to conventional rehabilitation.More high-quality RCTs are needed to prove the advantage of VR-based rehabilitation.As the COVID-19 pandemic continues,it is necessary to promote this rehabilitation model. | Linbo Peng Yi Zeng Yuangang Wu Haibo Si Bin Shen | 2022 | Chinese Medical Journal2022，，2： | 5 |
| 8 | The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs. | Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou | 2023 | Horticulture Research2023，10，5： | 3 |
| 9 | Prostate cancer tends to metastasize in the bone-mimicking microenvironment via activating NF-κB signaling显示文摘Prostate cancer preferentially metastasizes to the bone. However, the underlying molecular mechanisms are still unclear. To explore the effects of a bone-mimicking microenvironment on PC3 prostate cancer cell growth and metastasis, we used osteoblast differentiation medium(ODM; minimal essential medium alpha supplemented with L-ascorbic acid) to mimic the bone microenvironment. PC3 cells grown in ODM underwent epithelial-mesenchymal transition and showed enhanced colony formation, migration, and invasion abilities compared to the cells grown in normal medium. PC3 cells grown in ODM showed enhanced metastasis when injected in mice. A screening of signaling pathways related to invasion and metastasis revealed that the NF-κB pathway was activated, which could be reversed by Bay 11-7082, a NF-κB pathway inhibitor. These results indicate that the cells in different culture conditions manifested significantly different biological behaviors and the NF-κB pathway is a potential therapeutic target for prostate cancer bone metastasis. | Haibo Tong Chunlin Zou Siyuan Qin Jie Meng Evan T.Keller Jian Zhang Yi Lu | 2018 | The Journal of Biomedical Research2018，32，5： | 3 |
| 10 | High-definition colorful perovskite narrowband photodetector array enabled by laser-direct-writing显示文摘Narrowband photodetectors as specific spectral sensing pixels have drawn intense attention in multispectral detection due to their distinct characteristic of filter-free spectrum discrimination,in which the emerging halide lead perovskites witness a booming development in their performance and wavelength-selectivity from blue to near-infrared light.However,the challenge in integrating perovskite narrowband photodetectors on one chip imposes an impediment on practical application.In this work,the combination of laser-direct-writing and ion exchange is proposed as an efficient way to fabricate high-definition colorful sensing array with perovskite narrowband photodetector unit as pixel.Under laser irradiation,the photolysis of halocarbon solvent(CHCl_(3),CH_(3)CH_(2)I,etc)releases the halide ions,which brings the ion exchange and gives rise to slow-varying bandgap in single perovskite photoactive film.This ion exchange can be controlled via laser irradiation time and focus point,thus enabling precisely engineerable bandgap.By optimizing the process,it is successfully applied to develop patterned perovskite narrow blue and green photodetectors array with a high-definition of~53 ppi.We believe this result will make a great step forward to integrate multifunctional perovskite devices on one chip,which will pave the way for perovskite optoelectronic device to the commercial application. | Xiaobao Xu Yuhang Dong Yuanzhou Zhang Zeyao Han Jiaxin Liu Dejian Yu Yi Wei Yousheng Zou Bo Huang Jun Chen Haibo Zeng | 2022 | Nano Research2022，15，6： | 2 |
| 11 | Calibration of Mars Energetic Particle Analyzer (MEPA)显示文摘The first Mars exploration mission of China(Tianwen-1)is scheduled to be launched in 2020;a charged particle telescope,the Mars Energetic Particle Analyzer(MEPA),is carried as one of the payloads on the orbiter.The MEPA is designed to measure solar energetic particles(SEPs)and galactic cosmic rays(GCRs)in the near-Mars space and in the transfer orbit from Earth to Mars.Before the launch,the MEPA was calibrated in ground experiments with radioactive sources,electronic pulses,and accelerator beams.The calibration parameters,such as energy conversion constants,threshold values for the triggers,and particle identification criteria,were determined and have been stored for onboard use.The validity of the calibration parameters has been verified with radioactive sources and beams.The calibration results indicate that the MEPA can measure charged particles reliably,as designed,and that it can satisfy the requirements of the Tianwen-1 mission. | ShuWen Tang Yi Wang HongYun Zhao Fang Fang Yi Qian YongJie Zhang HaiBo Yang CunHui Li Qiang Fu Jie Kong XiangYu Hu Hong Su ZhiYu Sun YuHong Yu BaoMing Zhang Yu Sun ZhiPeng Sun | 2020 | Earth and Planetary Physics2020，4，4： | 2 |

| 13 | A swept fin-induced flow field with different height mounting gaps显示文摘In order to apply the air fin successfully and ensure the maneuverability of hypersonic vehicle, a key problem to be studied urgently is the heat flux brought by the fin mounting gap.The appearance of mounting gap and fin shaft can induce many complex flow structures which need more attentions to be investigated. Under Ma 6, Nano-tracer-based Planar Laser Scattering(NPLS)and Temperature Sensitive Paints(TSP) were applied to visualize and measure transient flow structures and heat flux distribution of a swept fin-induced flow field with different height mounting gaps. Complementarily, Reynolds-averaged N-S equations were solved with k-x SST turbulent model. The heat flux distribution results of numerical simulation and TSP observed the change of high heat flux region with different mounting gap, both in position and magnitude. The streamlines based on Computational Fluid Dynamics(CFD) and flow visualization results obtained by NPLS revealed the cause of high heat flux region. The high heat flux region in this flow field is mainly related to the reattachment of vortex and flow stagnation. The increase of gap height can lead to stronger gap overflow and shaft-induced horseshoe vortex, which are source of the high heat flux around the fin. The case with the highest mounting gap(4 mm) en-counters the most severe aerodynamic heating, both on the surface of fin and plate. Thus, under the premise of ensuring the flexibility of the fin, the gap should be set as small as possible. | Feng ZHANG Shihe YI Xiwang XU Haibo NIU Xiaoge LU | 2021 | Chinese Journal of Aeronautics2021，34，1： | 2 |
| 14 | Recent satellite-derived sea ice volume flux through the Fram Strait: 2011–2015显示文摘The Fram Strait(FS) is the primary region of sea ice export from the Arctic Ocean and thus plays an important role in regulating the amount of sea ice and fresh water entering the North Atlantic seas. A 5 a(2011–2015) sea ice thickness record retrieved from Cryo Sat-2 observations is used to derive a sea ice volume flux via the FS. Over this period, a mean winter accumulative volume flux(WAVF) based on sea ice drift data derived from passivemicrowave measurements, which are provided by the National Snow and Ice Data Center(NSIDC) and the Institut Francais de Recherche pour d'Exploitation de la Mer(IFREMER), amounts to 1 029 km^3(NSIDC) and1 463 km^3(IFREMER), respectively. For this period, a mean monthly volume flux(area flux) difference between the estimates derived from the NSIDC and IFREMER drift data is –62 km^3 per month(–18×10~6 km^2 per month).Analysis reveals that this negative bias is mainly attributable to faster IFREMER drift speeds in comparison with slower NSIDC drift data. NSIDC-based sea ice volume flux estimates are compared with the results from the University of Bremen(UB), and the two products agree relatively well with a mean monthly bias of(5.7±45.9) km^3 per month for the period from January 2011 to August 2013. IFREMER-based volume flux is also in good agreement with previous results of the 1990 s. Compared with P1(1990/1991–1993/1994) and P2(2003/2004–2007/2008), the WAVF estimates indicate a decline of more than 600 km^3 in P3(2011/2012–2014/2015). Over the three periods, the variability and the decline in the sea ice volume flux are mainly attributable to sea ice motion changes, and second to sea ice thickness changes, and the least to sea ice concentration variations. | BI Haibo WANG Yunhe ZHANG Wenfeng ZHANG Zehua LIANG Yu ZHANG Yi HU Wenmin FU Min HUANG Haijun | 2018 | Acta Oceanologica Sinica2018，37，9： | 2 |
| 15 | Difference of planktonic ciliate communities of the tropical West Pacific, the Bering Sea and the Arctic Ocean显示文摘Ciliates are important components in planktonic food webs,but our understanding of their community structures in different oceanic water masses is limited.We report pelagic ciliate community characteristics in three seas:the tropical West Pacific,the Bering Sea and the Arctic Ocean.Planktonic ciliate abundance had'bimodal-peak','surface-peak'and'DCM(deep chlorophyll a maximum layer)-peak'vertical distribution patterns in the tropical West Pacific,the Bering Sea and the Arctic Ocean,respectively.The abundance proportion of tintinnid to total ciliate in the Bering Sea(42.6%)was higher than both the tropical West Pacific(7.8%)and the Arctic Ocean(2.0%).The abundance proportion of small aloricate ciliates(10–20μm size-fraction)in the tropical West Pacific was highest in these three seas.The Arctic Ocean had higher abundance proportion of tintinnids in larger LOD(lorica oral diameter)size-class.Proportion of redundant species increased from the Arctic Ocean to the tropical West Pacific.Our result provided useful data to further understand ecology roles of planktonic ciliates in different marine habitats. | Chaofeng Wang Haibo Li Zhiqiang Xu Shan Zheng Qiang Hao Yi Dong Li Zhao Wuchang Zhang Yuan Zhao Gérald Grégori Tian Xiao | 2020 | Acta Oceanologica Sinica2020，39，4： | 2 |
| 16 | Involvement of the crebellum in sequential finger movement learning:Evidence from functional magnetic resonance imaging显示文摘Whether the cerebellum is involved in volun-tary motor learning or motor performance is the subject of a new debate. Using functional magnetic resonance imaging (fMRI), we examined cerebellar activation in eight volun-teers before and after an extended period of training. Activa-tion volume on both sides of cerebellum after learning was significantly reduced compared to that before learning even under the same motor frequency. Remarkably, while motor frequency for the training sequence was significantly higher than the control sequence after 41 d of learning, activation in the cerebellum for both sequences, with respect to activation loci and volumes, was very similar. These results suggest that the cerebellum was involved in motor learning but not motor performance. Changes of cerebellar activation from training thus appear to be associated with learning but not with im-provement on task performance. | ZHU Yihong DI Haibo YUAN Yi REN Jin'ge YU Wei ZHANG Zhaoqi GAO Jiahong WENG Xuchu CHEN Yizhang | 2005 | Chinese Science Bulletin2005，50，17： | 2 |
| 17 | Construction of Highly Emissive Pt(Ⅱ) Metallacycles upon Irradiation显示文摘Photoswitchable or photoactivatable fluorescent species have been found wide applications within supramolecular chemistry and materials science.In this study,we successfully constructed two highly emissive Pt(Ⅱ)metallacycles from the diarylethene ligands via coordination-driven self-assembly.Different from the most known fluorescent metallacycles,the obtained metallacycles have displayed'turn-on'fluorescence switching.They are non-fluorescent in solution,but they emit highly yellow or orange fluorescence under ultraviolet irradiation.The metallacycles were well characterized by 1H NMR,31P NMR and ESI-TOF-MS.The photochromic properties of the resultant metallacycles were investigated by 1H NMR,31P NMR,UV/Vis spectrum and fluorescence spectrum.Notably,NMR studies revealed that these two metallacycles featured excellent cyclization efficiency(90% conversion efficiency).Moreover,the closed-ring isomers of the metallacycles displayed relatively high quantum yield(ФF=0.5).DFT simulations demonstrated that the antiparallel configuration of the diarylethene ligand had an angle closed to 120°,which was more stable in energy compared to the parallel configuration,thus allowing for the facile construction of highly emissive metallacycles.We believe that such highly emissive metallacycles which are in-situ prepared upon irradiation can be used as new fluorescence materials for sensing and bioimaging in the future. | Yi Qin Ying Zhang Guangqiang Yin Yuxuan Wang Changwei Zhang Lijun Chen Hongwei Tan Xiaopeng Li Lin Xu Haibo Yang | 2019 | Chinese Journal of Chemistry2019，37，4： | 2 |
| 18 | Distribution of Different Biogeographical Tintinnids in Yellow Sea and Bohai Sea显示文摘There were different biogeographical tintinnids in the oceans. Knowledge of their distribution pattern and mixing was important to the understanding of ecosystem functions. Yellow Sea(YS) and Bohai Sea(BS) were semi-enclosed seas influenced by warm water intrusion and YS cold bottom water. The occurrence of tintinnids in YS and BS during two cruises(summer and winter) were investigated to find out: i) whether warm-water tintinnids appeared in YS and BS; ii) whether boreal tintinnids appeared in high summer; iii) the core area of neritic tintinnids and iv) how these different biogeographical tintinnids mixed. Our results showed that tintinnid community was dominated by neritic tintinnid. We confirmed the occurrence of warm-water tintinnids in summer and winter. In summer, they intruded into BS and mainly distributed in the upper 20 m where Yellow Sea Surface Warm Water(YSSWW) developed. In winter, they were limited in the surface water of central deep region(bottom depth >50 m) of YS where were affected by Yellow Sea Warm Water(YSWW). Boreal tintinnids occurred in YS in high summer(August) and in winter, while they were not observed in BS. In summer, the highest abundance of boreal tintinnids occurred in Yellow Sea Bottom Cold Water, indicating the presence of an oversummering stock. In winter, they were concentrated in the north of YSWW. Vertically, neritic tintinnids abundance was high in the bottom layers. Horizontally, high neritic tintinnids abundance in bottom layers occurred along the 50 m isobath coinciding with the position of front systems. Front systems were the core distribution area of neritic tintinnids. High abundance areas of warm-water and boreal tintinnids were clearly separated vertically in summer, and horizontally in winter. High abundance of neritic tintinnids rarely overlapped with that of warm-water or boreal tintinnids. | CHEN Xue LI Haibo ZHAO Yuan ZHAO Li DONG Yi ZHANG Wuchang XIAO Tian | 2018 | Journal of Ocean University of China2018，17，2： | 2 |
| 19 | Grazing by microzooplankton and copepods on the microbial food web in spring in the southern Yellow Sea,China显示文摘Assessment of microzooplankton and copepods grazing pressure on picoplankton is a key requirement for resolving the microbial food web efficiency.Although microzooplankton grazing on picoplankton has been extensively studied,the impact of microzooplankton on different groups of picoplankton,i.e.,heterotrophic bacteria,Synechococcus and picoeukaryotes have rarely been compared.Furthermore,in the very few existing studies there is no consistent evidence of an enhancing or restraining effect of copepods on picoplankton.More studies are needed to improve our understanding of the influence of microzooplankton and copepod on picoplankton.Dilution incubations and copepod addition incubations were performed during a cruise to the southern Yellow Sea on May 16-29,2007.The bulk grazing of microzooplankton and the calanoid copepod Cal anus sinicus on phytoplankton,flagellates and picoplankton was estimated.Stations were divided into either eutrophic or oligotrophic according to the nutrient and biological parameters.Picoplankton comprised a large part of the diet of microzooplankton in the central oligotrophic area,while phytoplankton was the main food of microzooplankton in the coastal eutrophic area.In the central oligotrophic area,microzooplankton preferred grazing on Synechococcus.After copepod addition,ciliate abundance decreased while Synechococcus abundance increased(382%,64%and 64%at three experimental stations,respectively),indicating strong grazing pressure of microzooplankton on Synechococcus.Our results suggest that Synechococcus might be an essential carbon source the planktonic food web in the oligotrophic waters of southern Yellow Sea. | Yuan Zhao Yi Dong Haibo Li Shiquan Lin Lingfeng Huang Tian Xiao Gerald Gregori Li Zhao Wuchang Zhang | 2020 | Marine Life Science & Technology2020，2，4： | 1 |
