| 1 | Anatomical and chemical characteristics associated with lodging resistance in wheat显示文摘Anatomical and chemical characteristics of stems affect lodging in wheat(Triticum aestivum L.) cultivars. Traits associated with lodging resistance, such as plant height, stem strength, culm wall thickness, pith diameter, and stem diameter, were extensively investigated in earlier studies. However, the solid stem trait was rarely considered. In this study, we measured a range of anatomical and chemical characteristics on solid and hollow stemmed wheat cultivars. Significant correlations were detected between resistance to lodging and several anatomical features, including width of mechanical tissue, weight of low internodes, and width of stem walls. Morphological features that gave the best indication of improved lodging resistance were increased stem width, width of mechanical tissue layer, and stem density. Multiple linear regression analysis showed that 99% of the variation in lodging resistance could be explained by the width of the mechanical tissue layer, suggesting that solid stemmed wheat has several anatomical features for increasing resistance to lodging. In addition, microsatellite markers GWM247 and GWM340 were linked to a single solid stem QTL on chromosome 3BL in a population derived from the cross Xinongshixin(solid stem)/Line 3159(hollow stem). These markers should be valuable in breeding wheat for solid stem. | Eryan Kong Dongcheng Liu Xiaoli Guo Wenlong Yang Jiazhu Sun Xin Li Kehui Zhan Dangqun Cui Jinxing Lin Aimin Zhang | 2013 | The Crop Journal2013，1，1： | 43 |
| 2 | Safety and feasibility of video-assisted thoracoscopic surgery for stage IIIA lung cancer显示文摘Objective: The current study was prospectively designed to explore the application of video-assisted thoracoscopic surgery(VATS) radical treatment for patients with stage IIIA lung cancer, with the primary endpoints being the safety and feasibility of this operation and the second endpoints being the survival and complications after the surgery.Methods: A total of 51 patients with radiologically or mediastinoscopically confirmed stage IIIA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher.Results: A total of 51 patients with non-small cell lung cancer(NSCLC) were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41(80.4%) had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50(98%) received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage(>1,000 mL), and the postoperative recovery was satisfactory. Up to 45 patients(88.2%) did not suffer from any perioperative complication, and 6(11.8%) experienced one or more complications.Conclusions: VATS radical treatment is a safe and feasible treatment for stage IIIA lung cancer. | Wenlong Shao Jun Liu Wehua Liang Hanzhang Chen Shuben Li Weiqiang Yin Xin Zhang Jianxing He | 2014 | Chinese Journal of Cancer Research2014，26，4： | 12 |
| 3 | First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed. | XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong | 2009 | Chinese Science Bulletin2009，54，24： | 11 |
| 4 | Oxidative stress, nutritional antioxidants and beyond显示文摘Free radical-induced oxidative stress contributes to the development of metabolic syndromes(Mets), including overweight,hyperglycemia, insulin resistance and pro-inflammatory state. Most free radicals are generated from the mitochondrial electron transport chain;under physiological conditions, their levels are maintained by efficient antioxidant systems. A variety of transcription factors have been identified and characterized that control gene expression in response to oxidative stress status.Natural antioxidant compounds have been largely studied for their strong antioxidant capacities. This review discusses the recent progress in oxidative stress and mitochondrial dysfunction in Mets and highlights the anti-Mets, anti-oxidative, and antiinflammatory effect of polyphenols as potential nutritional therapy. | Qiuping Guo Fengna Li Yehui Duan Chaoyue Wen Wenlong Wang Lingyu Zhang Ruilin Huang Yulong Yin | 2020 | Science China(Life Sciences)2020，63，6： | 10 |

| 6 | Diode-pumped power scalable Kerr-lens mode-locked Yb:CYA laser显示文摘Stable 68 fs pulses with the average power of 1.5 W is directly generated from a multimode diode-pumped Kerr-lens mode-locked Yb:CYA laser by separating the gain medium and Kerr medium. The repetition rate is about 50 MHz, resulting in a single pulse energy of 30 n J and a peak power of 0.44 MW. To the best of our knowledge, this is the highest single pulse energy ever produced from a mode-locked Yb:CYA oscillator. Our experimental results show that Yb:CYA crystal is an excellent candidate for multiwatt, sub-100 fs pulse generation in diode-pumped all-solid-state lasers. It is believed that the output power can be scalable to multi-W while the pulse duration is maintained with this simple method. | WENLONG TIAN YINGNAN PENG ZIYUE ZHANG ZIJIAO YU JIANGFENG ZHU XIAODONG XU ZHIYI WEI | 2018 | Photonics Research2018，6，2： | 8 |

| 9 | Synthesis of low-cost porous ceramic microspheres from waste gangue for dye adsorption显示文摘Low-cost porous ceramic microspheres from waste gangue were prepared by simple spray drying and subsequent calcination. Effects of calcination temperature on phase and microstructure evolution, specific surface area, pore structure, and dye adsorption mechanism of the microspheres were investigated systematically. Results showed that the microspheres were spherical, with some mesopores both on the surface and inside the spheres. The phase kept kaolinite after calcined at 800 and 900 ℃ and transformed into mullite at 1000 ℃. The microspheres calcined at 800 ℃ showed larger adsorption capacity and removal efficiency than those calcined at higher temperatures. Methylene blue(MB) and basic fuchsin(BF) removal efficiency reached 100% and 99.9% with the microsphere dosage of 20 g/L, respectively, which was comparable to that of other low-cost waste adsorbents used to remove dyes in the literature. Adsorption kinetics data followed the pseudosecond-order kinetic model, and the isotherm data fit the Langmuir isotherm model. The adsorption process was attributed to multiple adsorption mechanisms including physical adsorption, hydrogen bonding, and electrostatic interactions between dyes and gangue microspheres. The low-cost porous microspheres with excellent cyclic regeneration properties are promising absorbent for dyes in wastewater filtration and adsorption treatment. | Shu YAN Yiming PAN Lu WANG Jingjing LIU Zaijuan ZHANG Wenlong HUO Jinlong YANG Yong HUANG | 2018 | Journal of Advanced Ceramics2018，7，1： | 6 |
| 10 | The involvement of wheat U-box E3 ubiquitin ligase TaPUB1 in salt stress tolerance显示文摘U-box E3 ubiquitin ligases play important roles in the ubiquitin/26 S proteasome machinery and in abiotic stress responses. Ta PUB1-overexpressing wheat(Triticum aestivum L.) were generated to evaluate its function in salt tolerance. These plants had more salt stress tolerance during seedling and flowering stages, whereas the Ta PUB1-RNA interference(RNAi)-mediated knock-down transgenic wheat showed more salt stress sensitivity than the wild type(WT). Ta PUB1 overexpression upregulated the expression of genes related to ion channels and increased the net root Na+efflux, but decreased the net K+efflux and H+influx, thereby maintaining a low cytosolic Na+/K+ratio, compared with the WT. However,RNAi-mediated knock-down plants showed the opposite response to salt stress. Ta PUB1 could induce the expression of some genes that improved the antioxidant capacity of plants under salt stress. Ta PUB1 also interacted with Ta MP(Triticum aestivum α-mannosidase protein), a regulator playing an important role in salt response in yeast and in plants. Thus, low cytosolic Na+/K+ratios and better antioxidant enzyme activities could be maintained in wheat with overexpression of Ta PUB1 under salt stress. Therefore, we conclude that the U-box E3 ubiquitin ligase Ta PUB1 positively regulates salt stress tolerance in wheat. | Wenlong Wang Wenqiang Wang Yunzhen Wu Qinxue Li Guangqiang Zhang Ruirui Shi Junjiao Yang Yong Wang Wei Wang | 2020 | Journal of Integrative Plant Biology2020，62，5： | 6 |
| 11 | Optimal power allocation for secure directional modulation networks with a full-duplex UAV user显示文摘This paper makes an investigation of a secure unmanned aerial vehicle(UAV)-aided communication network based on directional modulation(DM). In this network, ground base station(GBS) acts as a control center to transmit confidential message and artificial noise(AN). The UAV user, moving along a linear flight trajectory, is intended to receive the useful information from GBS. At the same time, it also sends AN signals to further interference eavesdropper’s channel. Aiming at maximizing secrecy rate during the UAV flight process, a joint optimization problem is formulated with respect to power allocation(PA)factors, beamforming vector and AN projection matrices. For simplicity, maximum rate transmission, nullspace projection and the leakage-based method are applied to form the transmit beamforming vector, AN projection matrix at GBS, and AN projection vector at UAV user, respectively. Following this, the optimization problem reduces to a bivariate optimization programme with two PA factors. An alternating iterative algorithm(AIA) is proposed to optimize the two PA factors. Simulation results demonstrate that, compared to the half-duplex(HD) mode, the proposed strategy for full-duplex(FD) mode achieves a higher secrecy rate(SR) and outperforms the FD mode with fixed PA strategy. | Zaoyu LU Linlin SUN Shuo ZHANG Xiaobo ZHOU Jinyong LIN Wenlong CAI Jin WANG Jinhui LU Feng SHU | 2019 | Science China(Information Sciences)2019，62，8： | 6 |
| 12 | Twin structure of the lath martensite in low carbon steel显示文摘It has been well accepted that the martensites in quenched carbon steels exhibit two typical morphologies which are closely dependent on the carbon content, i.e. lath martensite in low carbon steels and lenticular martensite in high carbon steels. Based on conventional belief, the lath martensites in low carbon steels are with high density dislocations as the substructure, in contrast to twin substructure in lenticular high carbon martensite. In the present work, an intensive transmission electron microscopy investigation was made to characterize the microstructures of the lath martensite in a low carbon steel of 0.2 wt%C. It was found that lots of lath martensites consist of twin as their substructure, rather than high density dislocations. In addition, nanoscale precipitates cohering with ferrite matrix were found at the twin interfaces. The orientation relationships between the precipitates and the ferrite matrix are in good agreement with that of primitive hexagonal ω phase in titanium alloys and other bcc metals or alloys. | Pan Zhang Yulin Chen Wenlong Xiao Dehai Ping Xinqing Zhao | 2016 | Progress in Natural Science:Materials International2016，26，2： | 6 |
| 13 | Topologically Protected Edge State in Two-Dimensional Su–Schrieffer–Heeger Circuit显示文摘Topological circuits,an exciting feld just emerged over the last two years,have become a very accessible platform for realizing and exploring topological physics,with many of their physical phenomena and potential applications as yet to be discovered.In this work,we design and experimentally demonstrate a topologically nontrivial band structure and the associated topologically protected edge states in an RF circuit,which is composed of a collection of grounded capacitors connected by alternating inductors in the x and y directions,in analogy to the Su–Schriefer–Heeger model.We take full control of the topological invariant(i.e.,Zak phase)as well as the gap width of the band structure by simply tuning the circuit parameters.Excellent agreement is found between the experimental and simulation results,both showing obvious nontrivial edge state that is tightly bound to the circuit boundaries with extreme robustness against various types of defects.Te demonstration of topological properties in circuits provides a convenient and fexible platform for studying topological materials and the possibility for developing fexible circuits with highly robust circuit performance. | Shuo Liu Wenlong Gao Qian Zhang Shaojie Ma Lei Zhang Changxu Liu Yuan Jiang Xiang Tie Jun Cui Shuang Zhang | 2019 | Research2019，，1： | 6 |
| 14 | Long-term survival outcomes of video-assisted thoracic surgery for patients with non-small cell lung cancer显示文摘Background: Video-assisted thoracic surgery(VATS) has been shown to be a safe alternative to conventional thoracotomy for patients with non-small cell lung cancer(NSCLC). However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival.Methods: Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival.Results: Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients(69%). The median 5-year overall survival for Stage I, II, III and IV disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis.Conclusions: VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectable NSCLC. | Wenlong Shao Xinguo Xiong Hanzhang Chen Jun Liu Weiqiang Yin Shuben Li Xin Xu Xin Zhang Jianxing He | 2014 | Chinese Journal of Cancer Research2014，26，4： | 5 |
| 15 | Finite sensor selection algorithm in distributed MIMO radar for joint target tracking and detection显示文摘Due to the requirement of anti-interception and the limitation of processing capability of the fusion center, the subarray selection is very important for the distributed multiple-input multiple-output(MIMO) radar system, especially in the hostile environment. In such conditions, an efficient subarray selection strategy is proposed for MIMO radar performing tasks of target tracking and detection. The goal of the proposed strategy is to minimize the worst-case predicted posterior Cramer-Rao lower bound(PCRLB) while maximizing the detection probability for a certain region. It is shown that the subarray selection problem is NP-hard, and a modified particle swarm optimization(MPSO) algorithm is developed as the solution strategy. A large number of simulations verify that the MPSO can provide close performance to the exhaustive search(ES) algorithm. Furthermore, the MPSO has the advantages of simpler structure and lower computational complexity than the multi-start local search algorithm. | ZHANG Haowei XIE Junwei GE Jiaang ZHANG Zhaojian LU Wenlong | 2020 | Journal of Systems Engineering and Electronics2020，31，2： | 5 |
| 16 | High-temperature oxidation behavior and analysis of impedance spectroscopy of 7YSZ thermal barrier coating prepared by plasma spray-physical vapor deposition显示文摘Quasi-columnar structure 7YSZ(yttria stabilized zirconia) thermal barrier coatings(TBCs) are prepared by plasma spray-physical vapor deposition(PS-PVD) onto pretreated and un-pretreated bond coating, respectively. An isothermal oxidation experiment of 7YSZ TBCs is carried out in the atmosphere of 950 °C in order to simulate the high-temperature oxidation process of engine blades. The isothermal oxidation process of 7YSZ thermal barrier coatings is investigated systematically by impedance spectroscopy. The electrochemical physical model and equivalent circuit of columnar 7YSZ coatings are established. Results show that the isothermal oxidation kinetic curve of columnar 7YSZ thermal barrier coatings appears to follow the parabolic law. A pretreatment of bond coating can reduce the growth rate of the thermally grown oxide(TGO) layer, restraining the initiation and propagation of microcracks between YSZ and TGO layers. The oxidation rate constants of 7YSZ coatings with pretreated and un-pretreated bond coating are 0.101×10^(-12) cm^2·s^(-1) and 0.115 × 10^(-13) cm^2 ·s^(-1), respectively. Impedance analysis shows that the content of oxygen vacancies decreases and the density increases after the TGO layer is oxidized for 150 h. In addition, shrinkage microcracks formed by sintering during the oxidation process is the main reason for an increase of the capacitance and a decrease of the resistance in the grain boundary of YSZ. | Wenlong CHEN Min LIU Jifu ZHANG Ziqian DENG Jie MAO | 2018 | Chinese Journal of Aeronautics2018，31，8： | 5 |
| 17 | Facile fabrication of MoP nanodots embedded in porous carbon as excellent anode material for potassium-ion batteries显示文摘Molybdenum phosphide(MoP),owing to its abundant reserve and high theoretical capacity,is regarded as a promising anode material for potassium-ion batteries.However,it still suffers from the problems of acute volume expansion and weak diffusion kinetics.This study reports a simple method to synthesize a composite of molybdenum phosphide and porous carbon(MoP@PC)through simple mixing and annealing treatment.In the MoP@PC,lots of MoP nanodots with an average diameter of about 4 nm uniformly embedded in the petal-like porous carbon.The MoP@PC shows reversible capacities of 330 mAh g^(-1) at100 mA g^(-1) after 100 cycles,and ultra-long cycling stability with a capacity of 240 mAh g^(-1) after 1000 cycles at 1 A g^(-1) and 161 mAh g^(-1) after 1000 cycles at 5 A g^(-1).The structure of MoP@PC after charging-discharging cycles is also investigated by high resolution transmission electron microscope(HRTEM)and the result shows that MoP can still maintain the nanodot morphology without any agglomeration after 1000 cycles at 5 A g^(-1).The storage mechanism of potassium ions was studied as well,which reveals that MoP and potassium ion have a conversion reaction. | Zhanheng Yan Zhongyuan Huang Haihui Zhou Xinxin Yang Songlin Li Wenlong Zhang Fei Wang Yafei Kuang | 2021 | Journal of Energy Chemistry2021，30，3： | 5 |
| 18 | Multimetallic AuPd@Pd@Pt core-interlayer-shell icosahedral electrocatalysts for highly efficient oxygen reduction reaction显示文摘Incorporating Pt with core metals into Pt-based core-shell catalysts is regarded as a promising strategy to substantially enhance the catalytic properties towards oxygen reduction reaction(ORR) in fuel cells due to the synergetic effect between distinct metals. In this wok, ultrathin Pt skins with two atomic layers were epitaxially coated on as-prepared icosahedral Au_50Pd_50, Au_60Pd_40 and Au_66Pd_34 nanocrystal seeds,which are constructed with alloyed cores and Pd shells with different thickness. Through electron microscopic characterizations, Pd interlayers with tunable thickness of 3, 6, and 12 atomic layers can be found in the Au_66Pd_34@Pt, Au_60 Pd_40@Pt and Au_50Pd_50@Pt icosahedra, respectively. These icosahedral Au Pd@Pd@Pt nanocrystals show substantially enhanced activities and durabilities in electrocatalytic measurements towards ORR compared to Au_75Pd_25@Pt icosahedra without Pd interlayer and commercial Pt/C catalysts. Specifically, Au_60Pd_40@Pt icosahedra with 6 atomically thick Pd interlayer display the best electrocatalytic performances, whose mass activities before and after durability tests of 50,000 cycles are11.6 and 30.2 times, respectively, as high as that of the commercial Pt/C. | Qingfeng Xu Wenlong Chen Yucong Yan Zhemin Wu Yi Jiang Junjie Li Ting Bian Hui Zhang Jianbo Wu Deren Yang | 2018 | Science Bulletin2018，63，8： | 5 |
| 19 | Protective effects of taurine against muscle damage induced by diquat in 35 days weaned piglets显示文摘Background: Oxidative stress is a key factor that influences piglets' health. Taurine plays an imperative role in keeping the biological system from damage. This study was conducted to investigate the protective effect of taurine against muscle injury due to the secondary effect of diquat toxicity.Results: Our study found that taurine effectively and dose-dependently alleviated the diquat toxicity induced rise of feed/gain, with a concurrent improvement of carcass lean percentage. The plasma content of taurine was considerably increased in a dose-dependent manner. Consequently, dietary taurine efficiently improved the activity of plasma antioxidant enzymes. Furthermore, taurine attenuated muscle damage by restoring mitochondrial micromorphology, suppressing protein degradation and reducing the percentage of apoptotic cells in the skeletal muscle. Taurine supplementation also suppressed the genes expression levels of the antioxidant-, mitochondrial biogenesis-, and muscle atrophy-related genes in the skeletal muscle of piglets with oxidative stress.Conclusions: These results showed that the dose of 0.60% taurine supplementation in the diet could attenuate skeletal muscle injury induced by diquat toxicity. It is suggested that taurine could be a potential nutritional intervention strategy to improve growth performance. | Chaoyue Wen Fengna Li Qiuping Guo Lingyu Zhang Yehui Duan Wenlong Wang Jianzhong Li Shanping He Wen Chen Yulong Yin | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 5 |
| 20 | Tomography of the dynamic stress coefficient for stress wave prediction in sedimentary rock layer under the mining additional stress显示文摘In this study,the tomography of dynamic stress coefficient(TDSC)was established based on a mechanical model of stress wave propagation in bedding planes and a mathematical model of the stress wave attenuation in rock masses.The reliability of the TDSC was verified by a linear bedding plane model and field monitoring.Generally,the TDSC in the dynamic stress propagation of bedding planes increases with the following conditions:(1)the increase of the normal stiffness of the bedding plane,(2)the increase of the incident angle of the stress wave,(3)the decrease of the incident frequency of the stress wave,or(4)the growth of three ratios(the ratios of rock densities,elastic moduli,and the Poisson’s ratios)of rocks on either side of bedding planes.The additional stress weakens TDSC linearly and slowly during the stress wave propagation in bedding planes,and the weakening effect increases with the growth of the three ratios.Besides,the TDSC decreases exponentially in the rock mass as propagation distance increases.In a field case,the TDSC decreases significantly as vertical and horizontal distances increase and its wave range increases as vertical distance increases in the sedimentary rock layers. | Wenlong Shen Guocang Shi Yungang Wang Jianbiao Bai Ruifeng Zhang Xiangyu Wang | 2021 | International Journal of Mining Science and Technology2021，31，4： | 5 |
