| 2 | Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices. | Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng | 2016 | Light(Science & Applications)2016,5,1: | 36 |
| 3 | Evaluation of the yield and nitrogen use efficiency of the dominant maize hybrids grown in North and Northeast China显示文摘Breeding high-yielding and nutrient-efficient cultivars is one strategy to simultaneously resolve the problems of food security,resource shortage,and environmental pollution.However,the potential increased yield and reduction in fertilizer input achievable by using high-yielding and nutrient-efficient cultivars is unclear.In the present study,we evaluated the yield and nitrogen use efficiency(NUE) of 40 commercial maize hybrids at five locations in North and Northeast China in 2008 and 2009.The effect of interaction between genotype and nitrogen(N) input on maize yield was significant when the yield reduction under low-N treatment was 25%-60%.Based on the average yields achieved with high or low N application,the tested cultivars were classified into four types based on their NUE:efficient-efficient(EE) were efficient under both low and high N inputs,high-N efficient(HNE) under only high N input,low-N efficient(LNE) under only low N input,and nonefficient-nonefficient under neither low nor high N inputs.Under high N application,EE and HNE cultivars could potentially increase maize yield by 8%-10% and reduce N input by 16%-21%.Under low N application,LNE cultivars could potentially increase maize yield by 12%.We concluded that breeding for N-efficient cultivars is a feasible strategy to increase maize yield and/or reduce N input. | CHEN FanJun FANG ZenGuo GAO Qiang YE YouLiang JIA LiangLiang YUAN LiXing MI GuoHua ZHANG FuSuo | 2013 | Science China(Life Sciences)2013,56,6: | 27 |
| 4 | Positive impact of adding No.14v lymph node to D2 dissection on survival for distal gastric cancer patients after surgery with curative intent显示文摘Background:D2 lymphadenectomy has been increasingly regarded as standard surgical procedure for advanced gastric cancer(GC),while the necessity of No.14 v lymph node(14v) dissection for distal GC is still controversial.Methods:A total of 920 distal GC patients receiving at least a D2 lymph node dissection in Department of Gastric Cancer,Tianjin Medical University Cancer Institute and Hospital were enrolled in this study,of whom,243 patients also had the 14 v dissected.Other 677 patients without 14 v dissection were used for comparison.Results:Forty-five(18.5%) patients had 14 v metastasis.There was no significant difference in 3-year overall survival(OS) rate between patients with and without 14 v dissection.Following stratified analysis,in TNM stages I,II,IIIa and IV,14 v dissection did not affect 3-year OS;in contrast,patients with 14 v dissection had a significant higher 3-year OS than those without in TNM stages IIIb and IIIc.In multivariate analysis,14 v dissection was found to be an independent prognostic factor for GC patients with TNM stage IIIb/IIIc disease [hazard ratio(HR),1.568;95% confidence interval(CI):1.186-2.072;P=0.002].GC patients with 14 v dissection had a significant lower locoregional,especially lymph node,recurrence rate than those without 14 v dissection(11.7 % vs.21.1%,P=0.035).Conclusions:Adding 14 v to D2 lymphadenectomy may be associated with improved 3-year OS for distal GC staged TNM Ⅲb/Ⅲc. | Yuexiang Liang Liangliang Wu Xiaona Wang Xuewei Ding Hongmin Liu Bin Li Baogui Wang Yuan Pan Rupeng Zhang Ning Liu Han Liang | 2015 | Chinese Journal of Cancer Research2015,27,6: | 22 |
| 5 | Kinetics and equilibrium of adsorption of dissolved organic matter fractions from secondary effluent by fly ash显示文摘Fly ash was used as a low-cost adsorbent for removing dissolved organic matter (DOM) in secondary effluent. Batch experiments were conducted under various adsorbent dosages, pH, contact time, temperatures and DOM fractional characteristics. Under the optimum conditions of fly ash dosage of 15 g/L, temperature of 303 K and contact time of 180 min, a removal of 22.5% of the dissolved organic carbon (DOC), 23.7% of UV-254, 25.9% of the trihalomethanes precursors in secondary effluent was obtained. The adsorption of DOM fractions onto fly ash all followed the pseudo second-order kinetic model, and the hydrophilic fraction adsorption by fly ash also fitted the intraparticle diffusion model quite well. Freundlich and Langmuir models were applicable to the fly ash adsorption and their constants were evaluated. The maximum adsorption capacities of the adsorptions revealed that fly ash was more effective in adsorbing hydrophilic fraction than the acidic fractions. Structure changes of the DOM fractions after fly ash adsorption were also characterized via spectrum analyzing. Those mechanisms presented critical step toward improved efficiencies of fly ash adsorption via further surface-modification. | Liangliang Wei Kun Wang Qingliang Zhao Chunmei Xie Wei Qiu Ting Jia | 2011 | Journal of Environmental Sciences2011,23,7: | 21 |
| 6 | Disclosure of government financial information and the cost of local government's debt financing——Empirical evidence from provincial investment bonds for urban construction显示文摘China's slowing economic growth and rapid urbanization have made local government debt financing a significant issue.This study uses a sample of China's provincial government data for the 2006–2012 period to examine the effect of the disclosure of financial information by local governments on their debt financing costs.The results show that financial information disclosure is conducive to public supervision and enhances government credibility,leading to a decrease in the cost of debt financing.Furthermore,increased government economic intervention increases the strength of the association between financial information disclosure and the cost of debt financing.Increased government audit prevention function weakens the strength of the association between financial information disclosure and the cost of debt financing. | Zhibin Chen Jun Pan Liangliang Wang Xiaofeng Shen | 2016 | China Journal of Accounting Research2016,,3: | 15 |
| 7 | Fe2N nanoparticles boosting FeNx moieties for highly efficient oxygen reduction reaction in Fe-N-C porous catalyst显示文摘Replacing Pt-based electrocatalysts for the oxygen reduction reaction (ORR) with high performance and low-cost non-precious metal catalysts is crucial for the commercialization of fuel cells.Herein,we present a highly efficient Fe-N-C porous ORR electrocatalyst with FeNx moieties promoted by Fe2N nanoparticles derived from Fe-doped zeolitic imidazolate framework.The best-performing Fe-N-C/HPC-NH3 catalyst exhibits a superior ORR activity with an onset (E0) and half-wave (E1/2) potential of 0.945 and 0.803 V (RHE),respectively,which is comparable to those of the commercial Pt/C in acidic media.Probing and acid-leaching experiments prove that FeNx moieties play an important role in the ORR and the Fe2N can further improve the ORR activity.Density functional theory calculation reveals a synergistic effect that the existence of Fe2N weakens the adsorption of ORR intermediates on active sites and lowers the reaction free energy of the potential limiting step,thus facilitating the ORR.Both experimental evidence and theoretical analysis for the enhancement of ORR activity by Fe2N decoration in Fe-N-C catalyst might inspire a new strategy for rational design of high performance non-precious metal catalysts. | Xiao Liu Hong Liu Chi Chen Liangliang Zou Yuan Li Qing Zhang Bo Yang Zhiqing Zou Hui Yang | 2019 | Nano Research2019,12,7: | 14 |
| 8 | Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability. | Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang | 2021 | Signal Transduction and Targeted Therapy2021,6,3: | 13 |
| 9 | Activation of mTORC1 in subchondral bone preosteoblasts promotes osteoarthritis by stimulating bone sclerosis and secretion of CXCL12显示文摘Increasing evidences show that aberrant subchondral bone remodeling plays an important role in the development of osteoarthritis(OA).However,how subchondral bone formation is activated and the mechanism by which increased subchondral bone turnover promotes cartilage degeneration during OA remains unclear.Here,we show that the mechanistic target of rapamycin complex 1(mTORC1)pathway is activated in subchondral bone preosteoblasts(Osterix+)from OA patients and mice.Constitutive activation of mTORC1 in preosteoblasts by deletion of the mTORC1 upstream inhibitor,tuberous sclerosis 1,induced aberrant subchondral bone formation,and sclerosis with little-to-no effects on articular cartilage integrity,but accelerated posttraumatic OA development in mice.In contrast,inhibition of mTORC1 in preosteoblasts by disruption of Raptor(mTORC1-specific component)reduced subchondral bone formation and cartilage degeneration,and attenuated post-traumatic OA in mice.Mechanistically,mTORC1 activation promoted preosteoblast expansion and Cxcl12 secretion,which induced subchondral bone remodeling and cartilage degeneration during OA.A Cxcl12-neutralizing antibody reduced cartilage degeneration and alleviated OA in mice.Altogether,these findings demonstrate that mTORC1 activation in subchondral preosteoblasts is not sufficient to induce OA,but can induce aberrant subchondral bone formation and secrete of Cxcl12 to accelerate disease progression following surgical destabilization of the joint.Pharmaceutical inhibition of the pathway presents a promising therapeutic approach for OA treatment. | Chuangxin Lin Liangliang Liu Chun Zeng Zhong-Kai Cui Yuhui Chen Pinling Lai Hong Wang Yan Shao Haiyan Zhang Rongkai Zhang Chang Zhao Hang Fang Daozhang Cai Xiaochun Bai | 2019 | Bone Research2019,7,1: | 12 |

| 11 | Coupling Rice with Fish for Sustainable Yields and Soil Fertility in China显示文摘About 30 million hectares of rice are cultivated annually in China(FAOSTAT,2019).Because most rice fields are wellirrigated and suitable for fish living(‘fish’here refers to various aquatic animals like carps,prawns,crabs,soft shell turtles,etc.)(Fernando,1993),many efforts have been made to determine how well rice farming and aquaculture can be coupled as a rice-fish system(RFS),of which the same land and water produces both rice and aquatic products.With the technological guidance of RFSs and political supports from the Ministry of Agriculture and Rural Affairs of China since 2010(Supplemental Table 1),multiple types of large-scale,high-efficiency and technologically intensive RFSs are now being demonstrated in the main rice-growing areas of China(National Fisheries Technology Extension Centre,2019),and in total about 1.2 million hectares of rice fields are under RFSs. | GUO Liang HU Liangliang ZHAO Lufeng SHI Xiaoyu JI Zijun DING Lilian REN Weizheng ZHANG Jian TANG Jianjun CHEN Xin | 2020 | Rice science2020,27,3: | 11 |
| 12 | Transition of human diets and agricultural economy in Shenmingpu Site, Henan, from the Warring States to Han Dynasties显示文摘Historical records and archaeological remains indicate that the Chinese agricultural economy changed significantly from the Warring States (475-221 BC) to Han Dynasties (206 BC-220 AD), i.e., from rice-millet based agriculture to rice-millet-wheat based agriculture. However, the variation of human diets and the inner relationship between human diets and the agricultural transition during this period remain poorly understood. In this paper, the C and N stable isotopes from human and animal bones at the Shenmingpu site (SMPS), Xichuan County, Henan Province were analyzed. If some outliers (M34, M36, M102) were excluded, the mean 13C value (( 16.7±0.8)‰, n=15) of humans in Han Dynasties was dramatically lower than that in the Warring States (( 12.7±0.8)‰, n=14), indicating that the cultivation of rice and wheat, especially wheat, had been more widely popularized in Han Dynasties. Meanwhile, the range of 15N values of humans (6.6‰-9.3‰) in Han Dynasties was narrower than that of the Warring States (6.2‰-10.4‰), suggesting that the animal protein resources in human foods during Han Dynasties were more concentrated. The transition of human diets and the close relationship with the change of agricultural economy in SMPS were due to more stable society, the carryout of new agricultural policies, and the emergence of new agricultural tools in Han Dynasties. | HOU LiangLiang WANG Ning Lu Peng HU YaoWu SONG GuoDing WANG ChangSui | 2012 | Science China Earth Sciences2012,55,6: | 10 |
| 13 | Ultrafast hydrogen bond dynamics of liquid water revealed by terahertz-induced transient birefringence显示文摘The fundamental properties of water molecules,such as their molecular polarizability,have not yet been clarified.The hydrogen bond network is generally considered to play an important role in the thermodynamic properties of water.The terahertz(THz)Kerr effect technique,as a novel tool,is expected to be useful in exploring the low-frequency molecular dynamics of liquid water.Here,we use an intense and ultrabroadband THz pulse(peak electric field strength of 14.9 MV/cm,centre frequency of 3.9 THz,and bandwidth of 1–10 THz)to resonantly excite intermolecular modes of liquid water.Bipolar THz field-induced transient birefringence signals are observed in a free-flowing water film.We propose a hydrogen bond harmonic oscillator model associated with the dielectric susceptibility and combine it with the Lorentz dynamic equation to investigate the intermolecular structure and dynamics of liquid water.We mainly decompose the bipolar signals into a positive signal caused by hydrogen bond stretching vibration and a negative signal caused by hydrogen bond bending vibration,indicating that the polarizability perturbation of water presents competing contributions under bending and stretching conditions.A Kerr coefficient equation related to the intermolecular modes of water is established.The ultrafast intermolecular hydrogen bond dynamics of water revealed by an ultrabroadband THz pump pulse can provide further insights into the transient structure of liquid water corresponding to the pertinent modes. | Hang Zhao Yong Tan Liangliang Zhang Rui Zhang Mostafa Shalaby Cunlin Zhang Yuejin Zhao Xi-Cheng Zhang | 2020 | Light(Science & Applications)2020,9,1: | 10 |
| 14 | Preliminary 3D printing of large inclined-shaped alumina ceramic parts by direct ink writing显示文摘Three dimensional(3D)printing technology by direct ink writing(DIW)is an innovative complex shaping technology,possessing advantages of flexibility in fabrication,high efficiency,low cost,and environmental-friendliness.Herein,3D printing of complex alumina ceramic parts via DIW using thermally induced solidification with carrageenan swelling was investigated.The rheological properties of the slurry under different thermally-induced modes were systematically studied.The solidification properties of thermally-induced pastes with varying contents of carrageenan were optimized.The experimental results showed that the optimized paste consisting of 0.4 wt%carrageenan could be rapidly solidified at about 55℃,which could print inclined-plane more than 60°in vertical without support,resulting in better homogeneity of the green body.A nearly pore-free structure was obtained after sintering at 1600℃ for 2 h. | Liangliang YANG Xiaojun ZENG Allah DITTA Bo FENG Lizhong SU Yue ZHANG | 2020 | Journal of Advanced Ceramics2020,9,3: | 9 |
| 15 | Plant coexistence can enhance phytoextraction of cadmium by tobacco (Nicotiana tabacum L.) in contaminated soil显示文摘A mesocosm experiment was conducted to investigate whether plant coexistence affects cadmium (Cd) uptake by plant in contaminated soil.Tobacco (Nicotiana tabacum L.var.K326) and Japanese clover (Kummerowia striata (Thunb.) Schindl.) were used.Cadmium was applied as 3CdSO 4 ·8H 2 O in solution at three levels (0,1,and 3 mg/kg soil) to simulate an unpolluted soil and soils that were slightly and moderately polluted with Cd.Tobacco (crop),Japanese clover (non-crop),and their combination were grown under each Cd treatment.Compared to monoculture and under all Cd treatments,co-planting with Japanese clover did not affect tobacco biomass but significantly increased Cd concentration in all tobacco tissues and enhanced Cd accumulation in tobacco shoots and roots.Compared to monoculture,co-planting reduced soil pH and increased Cd bioavailability.For tobacco,co-planting with Japanese clover increased the Cd bioconcentration factor (BCF) in Cd contaminated soil.Japanese clover also accumulated substantial quantities of Cd in shoots and roots.Thus,total Cd uptake by the plants was much greater with co-planting than with monoculture.The results suggested that phytoextraction can be effectively increased through tobacco co-planting with Japanese clover in mildly Cd-contaminated soil. | Ling Liu Yuefang Li Jianjun Tang Liangliang Hu Xin Chen | 2011 | Journal of Environmental Sciences2011,23,3: | 9 |

| 17 | Fractional Fourier domain hopped communication method based on chirp modulation for underwater acoustic channels显示文摘To improve the data rate of underwater acoustic frequency-hopped communications, frequency hopping is applied to different orders of fractional Fourier domain(Fr FD), to enable non-intrusive, bandwidth-limited acoustic communications.An Fr FD frequency-hopped communication method based on chirp modulation, namely multiple chirp shift keying-Fr FD hopping(MCSK-Fr FDH), is proposed for underwater acoustic channels. Validated by both simulations and experimental results, this method can reach a bandwidth efficiency twice more than conventional frequency-hopped methods with the same data rate and anti-multipath capability, suggesting that the proposed method achieves a better performance than the traditional frequencyhopped communication in underwater acoustic communication channels. Results also show that in practical scenarios, the MCSKFr FDH system with longer symbol length performs better at the low signal-to-noise ratio(SNR), while the system with larger frequency sweeping range performs better at a high SNR. | Xingbin Tu Xiaomei Xu Zheguang Zou Liangliang Yang Jianming Wu | 2017 | Journal of Systems Engineering and Electronics2017,28,3: | 9 |
| 18 | Fate of secondary effluent dissolved organic matter during soil-aquifer treatment显示文摘The reduction of mass and trihalomethane formation potential (THMFP) of dissolved organic matter (DOM) and its fractions from secondary effluent during laboratory-scale soil-aquifer treatment (SAT) soil columns were studied. Reduction in dissolved organic carbon (DOC), absorbance of ultraviolet light at 254 nm (UV-254), biodegradable dissolved organic carbon (BDOC) and nonbiodegradable dis- solved organic carbon (NBDOC) for the bulk DOM averaged 72.35%, 53.98%, 97.49% and 35.33% across the soil columns, respectively. Using XAD-8 and XAD-4 resins, DOM was fractionated into 3 fractions: hydrophobic acid (HPO-A), transphilic acid (TPI-A) and hydrophilic fraction (HPI). HPO-A was removed by 61.06%, TPI-A by 54.86% and HPI by 74.95% as DOC as a consequence of the laboratory-scale SAT, respectively. The reduction of THMFP from HPO-A, TPI-A and HPI was 27.24%, 26.24% and 36.08%, respectively. Proton nuclear magnetic resonance (1H-NMR) spectra revealed that the HPO-A isolated from the secondary effluent contained more aromatic functional groups than the corresponding TPI-A. Fourier-transform infrared (FT-IR) spectrum analysis illustrated that TPI-A had decreased hydrocarbon and increased aromatics content in the SAT columns. Specific ultraviolet light absorbance (SUVA) and specific THMFP for each DOM fraction increased across the soil columns and HPI exhibited greater increase in both than HPO-A and TPI-A. The most problematic THM precursor was found to be HPO-A with its high quantity present in recharged water and high chlorine reactivity. | XUE Shuang ZHAO QingLiang WEI LiangLiang WANG LiNa LIU ZhiGang | 2007 | Chinese Science Bulletin2007,52,18: | 8 |

| 20 | Prognostic significance of lymphovascular infiltration in overall survival of gastric cancer patients after surgery with curative intent显示文摘Objective: Lymphovascular infiltration(LVI) is frequently detected in gastric cancer(GC) specimens. Studies have revealed that GC patients with LVI have a poorer prognosis than those without LVI.Methods: In total, 1,007 patients with curatively resected GC at Department of Gastric Cancer, Tianjin Medical University Cancer Institute and Hospital were retrospectively enrolled. The patients were categorized into two groups based on the LVI status: a positive group(PG;presence of LVI) and a negative group(NG;absence of LVI). The clinicopathological factors corrected with LVI and prognostic variables were analyzed. Additionally, a pathological lymphovascular-node(lvN) classification system was proposed to evaluate the superiority of its prognostic prediction of GC patients compared with that of the eighth edition of the N staging system.Results: Two hundred twenty-four patients(22.2%) had LVI. The depth of invasion and lymph node metastasis were independently associated with the presence of LVI. GC patients with LVI demonstrated a significantly lower overall survival(OS) rate than those without LVI(42.8% vs. 68.9%, respectively;P<0.001). In multivariate analysis,LVI was identified as an independent prognostic factor for GC patients(hazard ratio: 1.370;95% confidence interval: 1.094-1.717;P=0.006). Using strata analysis, significant prognostic differences between the groups were only observed in patients at stage I-IIIa or N0-2. The lvN classification was found to be more appropriate to predict the OS of GC patients after curative surgery than the pN staging system. The-2 log-likelihood of lvN classification(4,746.922) was smaller than the value of pN(4,765.196), and the difference was statistically significant(χ^2=18.434, P<0.001).Conclusions: The presence of LVI influences the OS of GC patients at stage Ⅰ-Ⅲ a or N0-2. LVI should be incorporated into the pN staging system to enhance the accuracy of the prognostic prediction of GC patients. | Liangliang Wu Yuexiang Liang Chen Zhang Xiaona Wang Xuewei Ding Chongbiao Huang Han Liang | 2019 | Chinese Journal of Cancer Research2019,31,5: | 8 |
