| 2 | First observations of low latitude whistlers using WHU ELF/VLF receiver system显示文摘The recently developed high-quality WHU ELF/VLF receiver system has been deployed in Suizhou, China(geomagnetic latitude 21.81°N, longitude 174.44°E, L=1.16) to detect low latitude extremely-low-frequency(ELF: 0.3-3 k Hz) and very-low-frequency(VLF: 3-30 k Hz) emissions originating from either natural or artificial sources since February 2016. During the first-month operation of the receiver system, a total of 3039 clear whistlers have been recorded at this low latitude station with the majority(97.0%) occurring on 28 February and 1 March 2016. Observed whistlers manifest various types including single one-hop, echo train, multi-flash, and multi-path. They tend to intensify after local midnight, reach the peak around 04-05 LT, and then weaken quickly. Both features of lower cutoff frequencies of most whistlers below ~1.6 k Hz and almost uniform dispersion for many successive multi-flash whistlers suggest that these whistlers propagate along the geomagnetic field lines in the duct mode. The computed dispersion varies between ~15 s^(1/2) and 23 s^(1/2) for observed one-hop whistlers and is greater than 50 s^(1/2) for three-hop echo train whistlers, indicating that the whistlers observed at the Suizhou station are low latitude whistlers. | CHEN YanPing NI BinBin GU XuDong ZHAO ZhengYu YANG GuoBin ZHOU Chen ZHANG YuanNong | 2017 | Science China(Technological Sciences)2017，60，1： | 12 |
| 3 | Petrogenesis of keratophyes in the Pingshui Group,Zhejiang:Constraints from zircon U-Pb ages and Hf isotopes显示文摘Zircon LA-ICP-MS U-Pb ages and Hf isotopic as well as whole-rock geochemical data are reported for keratophyes in the Pingshui Group, Zhejiang. The results are used to discuss their petrogenesis and geological significance. The keratophyes were dated at 904±8 to 906±10 Ma. These intermediate-felsic rocks are characterized by high LREE contents and depletion of HREE and HFSE (e.g., Nb, Ta, Ti, P), resembling arc-derived rocks. The keratophyes exhibit positive εHf(t) values of 8.6 to 15.4, consistent with their εNd(t) values of 6.4 to 7.9 but far away from those of crust-derived rocks. Such features indi-cate that they were likely originated from prompt reworking of juvenile crust by arc-continent collision during the early-Neoproterozoic assembly between the Cathaysia and Yangtze Blocks. Combining with their Hf model ages, we suggest that there may exist not only remarkable growth of juvenile crust at ca.1.3―1.1 Ga but also production of juvenile arc-derived crust along the southeastern margin of the Yangtze Block (e.g., the Pingshui area) at ca.1.0―0.9 Ga. | CHEN ZhiHong XING GuangFu GUO KunYi DONG YongGuan CHEN Rong ZENG Yong LI LongMing HE ZhengYu ZHAO Ling | 2009 | Chinese Science Bulletin2009，54，9： | 9 |
| 4 | A detailed investigation of low latitude tweek atmospherics observed by the WHU ELF/VLF receiver:2.Occurrence features and associated ionospheric parameters显示文摘As a companion paper to Zhou RX et al.(2020),this study describes application of the automatic detection and analysis module to identify all the tweek atmospherics detectible in the WHU ELF/VLF receiver data collected at Suizhou station during the period of 3 February through 29 February 2016.Detailed analysis of the identified low-latitude tweek events reveals that the occurrence rate varies considerably—from 800 to 6000 tweeks per day,and exhibits a strong diurnal and local time dependence,the peak occurring before local midnight.The diurnal variation of identified tweeks was similar to that of the lightning data obtained by the World-Wide Lightning Location Network(WWLLN)..Estimates of the propagation distance and ionospheric reflection height of tweek atmospherics suggest that the majority(~92%)of the low latitude tweeks originate from the lightning activity within a radius of 4000 km and that they are very likely to reflect from the lower ionospheric D-region at the height range of 75–85 km.At these lower ionospheric reflection altitudes,~74%of the corresponding electron densities from the tweek spectral measurements are within 24.5–27.5 cm^-3.The daily variation of estimated D-region electron densities in the considered period(February 2016)also exhibits a small overall increasing trend from early to later in the month. | Juan Yi XuDong Gu Wen Cheng XinYue Tang Long Chen BinBin Ni RuoXian Zhou ZhengYu Zhao Qi Wang LiQing Zhou | 2020 | Earth and Planetary Physics2020，4，3： | 8 |
| 5 | A detailed investigation of low latitude tweek atmospherics observed by the WHU ELF/VLF receiver:Ⅰ. Automatic detection and analysis method显示文摘As a dispersive wave mode produced by lightning strokes, tweek atmospherics provide important hints of lower ionospheric(i.e., D-region) electron density. Based on data accumulation from the WHU ELF/VLF receiver system, we develop an automatic detection module in terms of the maximum-entropy-spectral-estimation(MESE) method to identify unambiguous instances of low latitude tweeks.We justify the feasibility of our procedure through a detailed analysis of the data observed at the Suizhou Station(31.57°N, 113.32°E) on17 February 2016. A total of 3961 tweeks were registered by visual inspection;the automatic detection method captured 4342 tweeks, of which 3361 were correct ones, producing a correctness percentage of 77.4%(= 3361/4342) and a false alarm rate of 22.6%(= 981/4342).A Short-Time Fourier Transformation(STFT) was also applied to trace the power spectral profiles of identified tweeks and to evaluate the tweek propagation distance. It is found that the fitting accuracy of the frequency–time curve and the relative difference of propagation distance between the two methods through the slope and through the intercept can be used to further improve the accuracy of automatic tweek identification. We suggest that our automatic tweek detection and analysis method therefore supplies a valuable means to investigate features of low latitude tweek atmospherics and associated ionospheric parameters comprehensively. | RuoXian Zhou XuDong Gu KeXin Yang GuangSheng Li BinBin Ni Juan Yi Long Chen FuTai Zhao ZhengYu Zhao Qi Wang LiQing Zhou | 2020 | Earth and Planetary Physics2020，4，2： | 7 |
| 6 | New type of transverse moving box mechanism for pot seedling transplanting machine显示文摘The existing moving box mechanism pot seedling transplanting machine on the market moves too fast when the picked seedling is collected,which negatively impacts the seedling picking performance.In order to improve the performance,two types of variable speed continuous moving box schemes were designed in this study.The first scheme was to apply a spiral-gear moving box spiral shaft with sine curve characteristics in the box moving mechanism,whereas the second one was to change the circular gear in the moving box into an elliptical gear with a speed shifting transmission mechanism.The working mechanism of the mechanical structure was analyzed,and the kinematic model was established.A dynamic analysis of the slider mechanism was performed.A virtual prototype was established according to agronomic parameters,and the virtual prototype experiments were conducted in ADAMS.The physical prototype and the high-speed photography experiment were performed on the test bench of a transplanting machine frame.The theoretical analysis,virtual prototype and physical prototype test results were consistent,which verified the validity of the theoretical model,virtual prototype and physical prototype and ensured the feasibility of the system. | Maile Zhou Zhengyu Hua Jingyuan Wang Lei Wang Yun Zhao Daqing Yin | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 7 |
| 7 | Almost perfect sequences based on cyclic difference sets显示文摘The perfect sequences are so ideal that all out-of-phase autocorrelation coefficients are zero, and if the sequences are used as the coding modulating signal for the phase-modulated radar, there will be no interference of side lobes theoretically. However, it has been proved that there are no binary perfect sequences of period 4 < n≤ 12100. Hence, the almost perfect sequences with all out-of-phase autocorrelation coefficients as zero except one are of great practice in engineering. Currently, the cyclic difference set is one of most effective tools to analyze the binary sequences with perfect periodic autocorrelation function. In this article, two characteristic formulas corresponding to the autocorrelation and symmetric structure of almost perfect sequences are calculated respectively. All almost perfect sequences with period n, which is a multiple of 4, can be figured out by the two formulas. Several almost perfect sequences with different periods have been hunted by the program based on the two formulas and then applied to the simulation program and practical application for ionospheric sounding. | Chen Gang Zhao Zhengyu | 2007 | Journal of Systems Engineering and Electronics2007，18，1： | 6 |
| 8 | Application of the oblique ionogram as vertical ionogram显示文摘The vertical ionogram can provide the important ionospheric parameters, such as critical frequency, virtual height and electron density, for ionospheric research. The oblique ionosonde has the ability to detect the ionosphere over sea and other terrain where it is not practical to deploy vertical sounder and provide more ionograms with less transmitting and receiving devices. Therefore, the conversion of the oblique ionogram to vertical ionogram for obtaining the important ionospheric parameters is a very useful inversion technology. The experimental comparison between oblique and vertical detections was carried out in the equatorial ionospheric anomaly (EIA) region of south China on 25 and 26 August 2010. The oblique detecting path was from Wuhan to Shenzhen and the VI ionosonde was located in the midpoint of the oblique path. The oblique ionogram reversion results showed a small deviation of the critical frequency, minimum virtual height as well as the electron density profile of the ionospheric F layer, as compared with the real vertical observations. | CHEN Gang ZHAO ZhengYu ZHANG YuanNong YANG GuoBin ZHOU Chen HUANG Shuo LI Ting LI Ning SUN HengQing | 2012 | Science China(Technological Sciences)2012，55，5： | 5 |
| 9 | The development of a sensitive fluorescent protein-based transcript reporter for high throughput screening of negative modulators of lncRNAs显示文摘While the human genome is pervasively transcribed,<2%of the human genome is transcribed into protein-coding mRNAs,leaving most of the transcripts as noncoding RNAs,such as microRNAs and long-noncoding RNAs(lncRNAs),which are critical components of epigenetic regulation.lncRNAs are emerging as critical regulators of gene expression and genomic stability.However,it remains largely unknown about how lncRNAs are regulated.Here,we develop a highly sensitive and dynamic reporter that allows us to identify and/or monitor negative modulators of lncRNA transcript levels in a high throughput fashion.Specifically,we engineer a fluorescent fusion protein by fusing three copies of the PEST destruction domain of mouse ornithine decarboxylase(MODC)to the C-terminal end of the codon-optimized bilirubin-inducible fluorescent protein,designated as dBiFP,and show that the dBiFP protein is highly destabilized,compared with the commonly-used eGFP protein.We further demonstrate that the dBiFP signal is effectively down-regulated when the dBiFP and mouse lncRNA H19 chimeric transcript is silenced by mouse H19-specific siRNAs.Therefore,our results strongly suggest that the dBiFP fusion protein may serve as a sensitive and dynamic transcript reporter to monitor the inhibition of lncRNAs by microRNAs,synthetic regulatory RNA molecules,RNA binding proteins,and/or small molecule inhibitors so that novel and efficacious inhibitors targeting the epigenetic circuit can be discovered to treat human diseases such as cancer and other chronic disorders. | Zongyue Zeng Bo Huang Shifeng Huang Ruyi Zhang Shujuan Yan Xinyi Yu Yi Shu Chen Zhao Jiayan Lei Wenwen Zhang Chao Yang Ke Wu Ying Wu Liping An Xiaojuan Ji Cheng Gong Chengfu Yuan Linghuan Zhang Wei Liu Yixiao Feng Bo Zhang Zhengyu Dai Yi Shen Xi Wang Wenping Luo Rex C.Haydon Hue H.Luu Lan Zhou Russell R.Reid Tong-Chuan He Xingye Wu | 2018 | Genes & Diseases2018，5，1： | 4 |
| 10 | Optimizing polyphase sequences for orthogonal netted radar systems显示文摘Orthogonal netted radar systems (ONRS) can fundamentally improve the radar performance by using a group of specially designed orthogonal polyphase code signals which require a very low aperiodic autocorrelation peak sidelobe level, low aperiodic cross-correlation, and a good resilience to small Doppler shifts. However, the existing numerical solutions degrade severely in the presence of small Doppler shifts. A new set of polyphase sequences is presented with good correlation properties as well as resilience to Doppler shifts. These sequences are built by using numerical optimization based on correlation properties as well as the Doppler effects on matched filter outputs, which maintains the Doppler tolerance. The statistical simulated annealing algorithm and the greedy code search method are used to optimize the sequences. Correlation and Doppler results are compared with the best-known sequences and show to be superior. | Wenwu Chen Zhengyu Cai Rushan Chen Zhao Zhao | 2012 | Journal of Systems Engineering and Electronics2012，23，4： | 4 |
| 11 | PKM2-dependent glycolysis promotes the proliferation and migration of vascular smooth muscle cells during atherosclerosis显示文摘Increased glycolysis is involved in the proliferation and migration of vascular smooth muscle cells(VSMCs).Pyruvate kinase isoform M2(PKM2),a key rate-limiting enzyme in glycolysis,accelerates the proliferation and migration of tumor cells.Although the intracellular mecha nisms associated with oxidized low-density lipoprotein(oxLDL)-stimulated VSMC proliferation and migration have been extensively explored,it is still unclear whether oxLDL promotes the proliferation and migration of VSMCs by enhancing PKM2-dependent glycolysis.In the present study,we detected PKM2 expression and pyruvate kinase activity in oxLDL-treated VSMCs and explored the regulation of PKM2 in oxLDL-treated VSMCs and apoE^-/-mice.The results showed that PKM2 expression in VSMCs was higher in the intima than in the media in plaques from atherosclerotic rabbits.Moreover,PKM2 level in VSMCs was increased during atherosclerosis progression in apoE^-/-mice.Both PKM2 expression and pyruvate kinase activity were found to be upregulated by oxLDL stimulation in VSMCs.Shikonin(SKN),a specific inhibitor of PKM2,was found to inhibit the oxLDL-induced proliferation and migration in VSMCs,in addition to delaying the atherosclerosis progression in apoE^-/-mice.More importantly,oxLDL increased glucose uptake,ATP and lactate production,and the extracellular acidification rate in VSMCs,which could be reversed by SKN.Meanwhile,oxygen consumption rate was unchanged after oxLDL stimulation,suggesting that glycolysis is the main contributor to the energy supply in oxLDL-treated VSMCs.Our results suggest that oxLDL induces VSMC proliferation and migration by upregulating PKM2-dependent glycolysis,thereby contributing to the atherosclerosis progression.Thus,targeting PKM2-dependent glycolysis might provide a novel therapeutic approach for the treatment of atherosclerosis. | Xuezhu Zhao Fancheng Tan Xiaoru Cao Zhengyu Cao Bicheng Li Zhaoqian Shen Ye Tian | 2020 | Acta Biochimica et Biophysica Sinica2020，52，1： | 3 |
| 12 | Radio Wave Propagation Effects Produced by Chemical Releases in the Ionosphere显示文摘As an effective means to actively modify the ionosphere,chemical release can produce artificial ionospheric holes as a consequence of ionization depletion,which can greatly impact on radio wave propagation.In this paper,on the basis of the pre-study results on ionospheric disturbances produced by some representative chemical releases,the radio waves propagation effects of ionospheric holes that are produced by two different release species,water(H2O) and sulfur hexafluoride(SF6),had been investigated and simulated by the three-dimensional(3-D) numerical ray tracing.The results show that ① the appearance of various artificial ionospheric holes can lead to certain decrease of critical frequency in the ionosphere,and ② when the wave frequency exceeds the critical frequency,the rays should be multiple reflections or penetrate through the ionospheric hole and focus afterwards with the focus altitude elevated for higher frequencies.This work may provide the necessary theoretical support for chemical release experiments and the evaluation of radio wave propagation effects. | HU Yaogai ZHAO Zhengyu XIANG Wei | 2011 | Wuhan University Journal of Natural Sciences2011，16，3： | 3 |
| 13 | Numerical simulation of the propagation of electromagnetic waves in ionospheric irregularities显示文摘The characteristics of high-frequency(HF)electromagnetic(EM)wave propagation can be affected when EM waves propagate in the ionosphere.When ionospheric irregularities appear in the ionosphere,they can have a serious impact on the propagation of HF EM waves.In this study,the propagation of HF EM waves in ionospheric irregularities was investigated by numerical simulation.First,a twodimensional model of plasma bubbles was used to produce ionospheric irregularities in the ionosphere.A ray-tracing method was then utilized to simulate the propagation of HF radio waves in these ionospheric irregularities.Results showed that the propagation of HF radio waves in the ionosphere was more complex in ionospheric irregularities than without ionospheric irregularities.In addition,corresponding ionograms were synthesized by radio rays propagated in the ionosphere with these irregularities.The synthesized ionograms were then compared with the experimental ionograms recorded by an ionosonde.Results showed that spread F could be simulated on the ionograms when ionospheric irregularities occurred in the ionosphere.This result was consistent with the ionosonde observations. | Chun Hua Jiang LeHui Wei GuoBin Yang Chen Zhou ZhengYu Zhao | 2020 | Earth and Planetary Physics2020，4，6： | 3 |
| 14 | Design and Implementation of Hardware Architecture in Ionospheric Oblique Backscattering Sounding System显示文摘The ionospheric oblique backscattering sounding sys-tem can not only be used to detect the state of the ionosphere and the condition of high frequency channel in real time, but also be used for over-the-horizon sounding. Therefore, it has a very high military and civil value. For the characteristics of ionospheric oblique backscattering sounding, such as long sounding distance, wake echo, strong background noise, slow moving target, etc., a hardware platform of ionospheric oblique backscattering sounding system is designed. This platform adopts the technology of soft-ware radio and is designed as a new kind of general purpose, modularized, software-based ionosonde that is based on the VXI (Versa module eurocard eXtensions for Instrumentation) bus. This hardware platform has been successfully used in actual iono-spheric oblique backscattering sounding, and the experimental results demonstrate that this system can satisfy the requirements. | SHI Shuzhu ZHAO Zhengyu YANG Guobin ZHANG Yuannong LIU Ruiyuan | 2009 | Wuhan University Journal of Natural Sciences2009，14，1： | 3 |
| 15 | Radiation belt electron scattering by whistler-mode chorus in the Jovian magnetosphere: Importance of ambient and wave parameters显示文摘Whistler-mode chorus waves are regarded as an important acceleration mechanism contributing to the formation of relativistic and ultra-relativistic electrons in the Jovian radiation belts. Quantitative determination of the chorus wave driven electron scattering effect in the Jovian magnetosphere requires detailed information of both ambient magnetic field and plasma density and wave spectral property, which however cannot be always readily acquired from observations of existed missions to Jupiter. We therefore perform a comprehensive analysis of the sensitivity of chorus induced electron scattering rates to ambient magnetospheric and wave parameters in the Jovian radiation belts to elaborate to which extent the diffusion coefficients depend on a number of key input parameters. It is found that quasi-linear electron scattering rates by chorus can be strongly affected by the ambient magnetic field intensity, the wave latitudinal coverage, and the peak frequency and bandwidth of the wave spectral distribution in the Jovian magnetosphere, while they only rely slightly on the background plasma density profile and the peak wave normal angle, especially when the wave emissions are confined at lower latitudes. Given the chorus wave amplitude, chorus induced electron scattering rates strongly depend on Jovian L-shell to exhibit a tendency approximately proportional to L_J^3. Our comprehensive analysis explicitly demonstrates the importance of reliable information of both the ambient magnetospheric state and wave distribution property to understanding the dynamic electron evolution in the Jovian radiation belts and therefore has implications for future mission planning to explore the extreme particle radiation environment of Jupiter and its satellites. | BinBin Ni Jing Huang YaSong Ge Jun Cui Yong Wei XuDong Gu Song Fu Zheng Xiang ZhengYu Zhao | 2018 | Earth and Planetary Physics2018，2，1： | 3 |
| 16 | Modification of physicochemical properties and degradation of barley flour upon enzymatic extrusion显示文摘In order to evaluate the application potential of enzyme-extruded barley flour(EEBF)in the brewing of whole-barley beer,the physicochemical properties,mashing and fermentation effects of EEBF were studied,and conventional extruded barley flour(CEBF)and steam-cooked barley flour(SCBF)were taken as controls.The water solubility index(WSI)of EEBF(46.88%-52.63%)was much higher than that of CEBF(6.70%)and SCBF(4.59%).The results of degree of gelatinization(DG)and enthalpy(ΔH)suggested that EEBF was almost completely gelatinized,and the rapid visco analyzer(RVA)exhibited that the peak viscosity of EEBF was drastically reduced.The weight-average molecular weight of EEBF(<10^(6) g/mol)was significantly lower than that of CEBF and SCBF.Scanning electron microscopy(SEM)showed that the heat-treatments caused starch granules to break and aggregate,and there were many hydrolyzed pores on the surface of EEBF.Both the long-and short-range order of EEBF were destroyed.Although EEBF caused serious filtration blocking,it greatly improved the alcohol content of finished beer(5.41%vol).Overall,the thermal modification of barley flour by enzyme-extrusion meets the needs of fermentation,and could improve the problem of limited leaching of unmalted barley,which was benefit for the production of whole-barley beer. | Shuna Zhao Aiquan Jiao Yueyue Yang Qing Liu Wenqi Wu Zhengyu Jin | 2022 | Food Bioscience2022，45，1： | 2 |
| 17 | A New Location Precision Model for Multi-Static Over-the-Horizon Radar System显示文摘In this paper, a multi-static system working in an active way is made up of ionospheric oblique backscatter sounding system (IOBSS) and two separate receiving stations, which adopts discontinuous wave mechanism. We have advanced a new model that contains skywave condition to locate over-the-horizon targets. We use a single quasi-parabolic (QP) ionosphere model and an analytic ray-tracing program to obtain the coordinate registration (CR) index, which changes skywave group range to ground range. Also, IOBSS and other two receiving stations use this distance information to locate the target which is far away from the system. The analytic expression for the geometric dilution of precision (GDOP) under different station deployments are obtained, which shows GDOP is influenced by the system measurement precision, the stations' coordinates, and CR index. By computer simulation, we find that GDOP of isosceles right triangle deployment is smaller than that of line deployment and location precision will be improved with increasing base line length. The results indicate that this model is practicable with an acceptable range of error (less than 500 m under certain conditions in this paper). | SONG Jun, ZHAO Zhengyu, ZHOU Chen School of Electronic Information, Wuhan University, Wuhan 430072, Hubei, China | 2010 | Wuhan University Journal of Natural Sciences2010，15，2： | 2 |
| 18 | A visualized study of interfacial behavior of air–water two-phase flow in a rectangular Venturi channel显示文摘A visualized investigation was carried out on the effect of the diverging angle on the bubble motion and interfacial behavior in a Venturi-type bubble generator.It was found two or three large vortexes formed in the diverging section,resulting in strong reentrant jet flow in the front of the bubbles or slugs rushing out of the throat.The jet flow in return bumps into the ongoing bubbles or slugs,leading to strong interaction between the gas and liquid phases.The diverging angle has significant influence on the reentrant flow process and the performance of the bubble generator as well.Increasing the diverging angle results in the reentrant flow moving further forward to the upstream and intensifies the interaction between the two phases.As a consequence,the breakup or collapse of bubbles becomes more violent,whereby finer bubbles are generated.As such,the reentrant flow strongly links to the performance of the Venturi channel taken as a bubble generator,and that a moderate increase in the diverging angle can improve its performance without additional increase in flow resistance like that by increasing liquid flow rate. | Jiang Huang Licheng Sun Min Du Zhengyu Mo Liang Zhao | 2018 | Theoretical & Applied Mechanics Letters2018，8，5： | 2 |

| 20 | Doppler estimating and compensating method based on phase显示文摘According to the Doppler sensitive of the phase coded pulse compression signal,a Doppler estimating and compensating method based on phase is put forward to restrain the Doppler sidelobes,raise the signal-to-noise ratio and improve measuring resolution.The compensation method is used to decompose the echo to amplitude and phase,and then compose the new compensated echo by the amplitude and the nonlinear component of the phase. Furthermore the linear component of the phase can be used to estimate the Doppler frequency shift.The computer simulation and the real data processing show that the method has accurately estimated the Doppler frequency shift, successfully restrained the energy leakage on spectrum,greatly increased the echo signal-to-noise ratio and improved the detection performance of the radio system in both time domain and frequency domain. | Chen Gang Zhao Zhengyu Nie Xuedong Shi Shuzhu Yang Guobin Su Fanfan | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 2 |
