| 1 | 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 |

| 3 | 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 |

Scaling of CMOS logic technology from 32 to 22 nm node meets more critical issues and needs some significant changes of the technology, as well as integration of the advanced processes. This paper will review the key processing technologies which can be potentially integrated into 22 nm and beyond technology nodes, including double patterning technology with high NA water immersion lithography and EUV lithography, new device architectures, high K/metal gate (HK/MG) stack and integration technology, mobility enhancement technologies, source/drain engineering and advanced copper interconnect technology with ultra-low-k process. | HUANG Ru WU HanMing KANG JinFeng XIAO DeYuan SHI XueLong AN Xia TIAN Yu WANG RunSheng ZHANG LiangLiang ZHANG Xing WANG YangYuan | 2009 | Science in China(Series F)2009，52，9： | 8 |
| 5 | 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 |
| 6 | Tuning Superhydrophobic Materials with Negative Surface Energy Domains显示文摘Hydrophobic/superhydrophobic materials with intrinsic water repellence are highly desirable in engineering fields including antiicing in aerocrafts,antidrag and anticorrosion in ships,and antifog and self-cleaning in optical lenses,screen,mirrors,and windows.However,superhydrophobic material should have small surface energy(SE)and a micro/nanosurface structure which can reduce solid-liquid contact significantly.The low SE is generally found in organic materials with inferior mechanical properties that is undesirable in engineering.Intriguingly,previous theoretical calculations have predicted a negative SE forθ-alumina(θ-Al_(2)O_(3)),which inspires us to use it as a superhydrophobic material.Here,we report the experimental evidence of the small/negative SE ofθ-Al_(2)O_(3) and aθ-Al_(2)O_(3)-based superhydrophobic coating prepared by one-step scalable plasma arcing oxidation.The superhydrophobic coating has complete ceramic and desired micro/nanostructure and therefore exhibits excellent aging resistance,wear resistance,corrosion resistance,high-temperature tolerance,and burning resistance.Owing to the rarity of the small/negative SE in inorganic materials,the concept to reduce SE byθ-Al_(2)O_(3) may foster a blowout to develop robust superhydrophobicity by complete inorganic materials. | Zhongzhen Wu Liangliang Liu Shunning Li Shunping Ji Pinghu Chen Suihan Cui Zhengyong Ma Yuchang Weng Qian Huang Zhongcan Wu Hao Wu Yuan Lin Ricky KYFu Hai Lin Xiubo Tian Paul KChu Feng Pan | 2019 | Research2019，，1： | 6 |

| 8 | Elevated preoperative plasma D-dimer dose not adversely affect survival of gastric cancer after gastrectomy with curative intent: A propensity score analysis显示文摘Objective: Elevated plasma D-dimer has been reported to be associated with advanced tumor stage and poor survival in several types of malignancies. The purpose of this study was to assess the potential impact of preoperative plasma D-dimer level(PDL) on overall survival(OS) of gastric cancer(GC) patients undergoing curative surgery by applying propensity score analysis.Methods: A total of 1,025 curatively resected GC patients in Tianjin Medical University Cancer Institute &Hospital were enrolled. Patients were categorized into two groups based on preoperative PDL: the elevated group(EG) and the normal group(NG). To overcome bias due to the different distribution of covariates for the two groups, a one-to-one match was applied using propensity score analysis, after matching, prognostic factors were analyzed.Results: In analysis for the whole study series, patients in the EG were more likely to have a larger proportion of tumor size ≥5 cm(67.5% vs. 55.8%, P=0.006), elder mean age(64.0±10.8 years vs. 60.5±11.6 years, P<0.001) and advanced tumor(T), node(N), and TNM stage. Patients with elevated PDL demonstrated a significantly lower 5-year OS than those with normal PDL(27.0% vs. 42.6%, P<0.001), however, the PDL was not an independent prognostic factor for OS in multivariate analysis [hazard ratio: 1.13, 95% confidence interval(95% CI): 0.92–1.39,P=0.236]. After matching, 163 patients in the EG and 163 patients in the NG had the same characteristics. The 5-year OS rate for patients in the EG was 27.0% compared with 25.8% for those in the NG(P=0.809, log-rank).Conclusions: The poor prognosis of GC patients with elevated preoperative PDL was due to the advanced tumor stage and elder age rather than the elevated D-dimer itself. | Yuexiang Liang Donglei He Liangliang Wu Xuewei Ding Xiaona Wang Baogui Wang Rupeng Zhang Han Liang | 2018 | Chinese Journal of Cancer Research2018，30，2： | 6 |
| 9 | Synthesis and characterization of N-aryloxo-functionalized β-ketoiminate rare-earth complexes and their catalytic activity for the polymerization of ε-caprolactone显示文摘The synthesis and characterization of dimeric rareearth amides stabilized by a dianionic N-aryloxo functionalized β-ketoiminate ligand are described.Reactions of 4-(2-hydroxy-5-methyl-phenyl) imino-2-pentanone(LH2) with Ln[N(SiMe3)2]3(μ-Cl)Li(THF)3 in a 1:1 molar ratio in THF gave the dimeric rare-earth amido complexes [LLn{N(SiMe3)2}(THF)]2 [Ln = Nd(1),Sm(2),Yb(3),Y(4)].These complexes were well characterized,and the definitive molecular structures of complexes 3 and 4 were determined.It was found that complexes 1― 4 can initiate the ring-opening polymerization of ε-caprolactone,and the ionic radii of the central metals have significant effect on the catalytic activity. | HAN XiangZong WU LiangLiang YAO YingMing ZHANG Yong SHEN Qi | 2009 | Chinese Science Bulletin2009，54，20： | 5 |
| 10 | Heterogeneously integrated,superconducting silicon-photonic platform for measurementdevice-independent quantum key distribution显示文摘Integrated photonics provides a route to both miniaturization of quantum key distribution(QKD)devices and enhancing their performance.A key element for achieving discrete-variable QKD is a singlephoton detector.It is highly desirable to integrate detectors onto a photonic chip to enable the realization of practical and scalable quantum networks.We realize a heterogeneously integrated,superconducting silicon-photonic chip.Harnessing the unique high-speed feature of our optical waveguide-integrated superconducting detector,we perform the first optimal Bell-state measurement(BSM)of time-bin encoded qubits generated from two independent lasers.The optimal BSM enables an increased key rate of measurement-device-independent QKD(MDI-QKD),which is immune to all attacks against the detection system and hence provides the basis for a QKD network with untrusted relays.Together with the timemultiplexed technique,we have enhanced the sifted key rate by almost one order of magnitude.With a 125-MHz clock rate,we obtain a secure key rate of 6.166 kbps over 24.0 dB loss,which is comparable to the state-of-the-art MDI-QKD experimental results with a GHz clock rate.Combined with integrated QKD transmitters,a scalable,chip-based,and cost-effective QKD network should become realizable in the near future. | Xiaodong Zheng Peiyu Zhang Renyou Ge Liangliang Lu Guanglong He Qi Chen Fangchao Qu Labao Zhang Xinlun Cai Yanqing Lu Shining Zhu Peiheng Wu Xiao-Song Ma | 2021 | Advanced Photonics2021，3，5： | 5 |
| 11 | In-situ optimizing the valence configuration of vanadium sites in NiV-LDH nanosheet arrays for enhanced hydrogen evolution reaction显示文摘Developing the highly active, cost-effective, environmental-friendly, and ultra-stable nonprecious electrocatalysts for hydrogen evolution reaction(HER) is distinctly indispensable for the large-scale practical applications of hydrolytic hydrogen production. Herein, we report the synthesis of well-integrated electrode, NiV layered double hydroxide nanosheet array grown in-situ on porous nickel foam(abbreviated as in-NiV-LDH/NF) via the facile one-step hydrothermal route. Interestingly, the valence configuration of vanadium(V) sites in such NiV-LDH are well dominated by the innovative use of NF as the reducing regulator, achieving the reassembled in-NiV-LDH/NF with a high proportion of trivalent V ions(V3+), and then an enhanced intrinsic electrocatalytic HER activity. The HER testing results show that the in-NiVLDH/NF drives the current densities of 10 and 100 mA cm-2 at extremely low overpotentials of 114 and 245 mV without iR-compensation respectively, even outperforms commercial 20 wt% Pt/C at the large current density of over 80 mA cm-2 in alkaline media, as well as gives robust catalytic durability of at least 100 h in both alkaline and neutral media. More importantly, this work provides a fresh perspective for designing bimetal(oxy) hydroxides electrocatalysts with efficient hydrogen generation. | Danyang He Liyun Cao Jianfeng Huang Koji Kajiyoshi Jianpeng Wu Changcong Wang Qianqian Liu Dan Yang Liangliang Feng | 2020 | Journal of Energy Chemistry2020，29，8： | 5 |
| 12 | Research on fault detection method for heat pump air conditioning system under cold weather显示文摘Building energy consumption accounts for nearly 40% of global energy consumption, HVAC(Heating, Ventilating,and Air Conditioning) systems are the major building energy consumers, and as one type of HVAC systems, the heat pump air conditioning system, which is more energy-efficient compared to the traditional air conditioning system, is being more widely used to save energy. However, in northern China, extreme climatic conditions increase the cooling and heating load of the heat pump air conditioning system and accelerate the aging of the equipment, and the sensor may detect drifted parameters owing to climate change. This non-linear drifted parameter increases the false alarm rate of the fault detection and the need for unnecessary troubleshooting.In order to overcome the impact of the device aging and the drifted parameter, a Kalman filter and SPC(statistical process control) fault detection method are introduced in this paper. In this method, the model parameter and its standard variance can be estimated by Kalman filter based on the gray model and the real-time data of the air conditioning system. Further, by using SPC to construct the dynamic control limits, false alarm rate is reduced.And this paper mainly focuses on the cold machine failure in the component failure and its soft fault detection.This approach has been tested on a simulation model of the 'Sino-German Energy Conservation Demonstration Center' building heat pump air-conditioning system in Shenyang, China, and the results show that the Kalman filter and SPC fault detection method is simple and highly efficient with a low false alarm rate, and it can deal with the difficulties caused by the extreme environment and the non-linear influence of the parameters, and what's more, it provides a good foundation for dynamic fault diagnosis and fault prediction analysis. | Liangliang Sun Jianghua Wu Haiqi Jia Xuebin Liu | 2017 | Chinese Journal of Chemical Engineering2017，25，12： | 5 |
| 13 | Simplified mathematical model of inter-turn short circuit of field windings in hydro-generators and its application显示文摘Inter-turn short circuit of field windings is a common electrical fault of generators.Simulation is an important method of investigating the fault and providing data support for fault monitoring.However,huge numbers of pole pairs and damper loops in large hydro-generators would lead to lengthy calculation time,hindering scientific research and engineering application.To deal with this problem,we analyze a theoretical basis for a damper winding simplified model and then propose an equivalent treatment method.Through the analysis of steady-state current harmonic characteristics of generators with different stator winding configurations during the fault,the simplified models suitable for steady-state calculation are derived from two aspects,namely,additional rotor harmonic current frequency characteristics and the relationship of the amplitude as well as the phase of each branch current of the stator.The calculation and experimental results of the two simplified models are then compared to verify the models' correctness.A calculation example of the Three Gorges left bank VGS generator shows few deviations between the calculation results of the simplified model and the original model.Moreover,the calculation time using the simplified model is 1/1500 that using the original model,which provides a more effective tool for on-line fault monitoring.Finally,the sensitivity-verification application of the fault-monitoring scheme based on the stator steady-state unbalanced current RMS is depicted.The result shows that the scheme can monitor two-turn short circuits of field windings in the Three Gorges generator and provide high sensitivity. | HAO LiangLiang WU JunYong SUN YuGuang WANG XiangHeng | 2013 | Science China(Technological Sciences)2013，56，4： | 5 |

| 15 | The comparison of biomarkers released by hydropyrolysis and Soxhlet extraction from source rocks of different maturities显示文摘The Permian Dalong Formation(P2d) source rocks from the mature Guangyuan outcrop section and the overmature Wangcang outcrop section in Sichuan Basin were selected.The Soxhlet extraction and kerogen catalytic HyPy were conducted on the P2d source rocks.The biomarkers obtained by both methods were compared to discuss their difference and the influence extent of thermal maturation on covalently bound biomarkers.The results show that covalently bound biomarkers can hardly be correlated to the corresponding free biomarkers due to severe thermal alterations and/or interference of migrated hydrocarbons in both outcrop sections and thermal maturation have much lower influence on covalently bound biomarkers in kerogens than on free biomarkers in Soxhlet extracts.The application of HyPy in study of biomarker geochemistry can reduce the thermal maturation effect on biomarkers(Ro≤2.4%) to a greater extent and the interference of migrated hydrocarbons between interbedded layers.The covalently bound biomarkers released by HyPy are useful in the study of biomarker geochemistry and oil-source correlation on high-overmature source rocks. | WU LiangLiang LIAO YuHong FANG YunXin GENG AnSong | 2013 | Chinese Science Bulletin2013，58，3： | 4 |

| 17 | Numerical simulation and experimental validation of gas–solid flow in the riser of a dense fluidized bed reactor显示文摘Gas–solid flow in the riser of a dense fluidized bed using Geldart B particles(sand),at high gas velocity (7.6–15.5 m/s)and with comparatively high solid flux(140–333.8 kg/m2 s),was investigated experimentally and simulated by computational fluid dynamics(CFD),both two-and three-dimensional and using the Gidaspow,O’Brien-Syamlal,Koch-Hill-Ladd and EMMS drag models.The results predicted by EMMS drag model showed the best agreement with experimental results.Calculated axial solids hold-up pro- files,in particular,are well consistent with experimental data.The flow structure in the riser was well represented by the CFD results,which also indicated the cause of cluster formation.Complex hydrody- namical behaviors of particle cluster were observed.The relative motion between gas and solid phases and axial heterogeneity in the three subzones of the riser were also investigated,and were found to be consistent with predicted flow structure.The model could well depict the difference between the two exit configurations used,viz.,semi-bend smooth exit and T-shaped abrupt exit.The numerical results indicate that the proposed EMMS method gives better agreement with the experimental results as compared with the Gidaspow,O’Brien-Syamlal,Koch-Hill-Ladd models.As a result,the proposed drag force model can be used as an efficient approach for the dense gas–solid two-phase flow. | Xueyao Wang Fan Jiang xiang xu Shengdian Wang Xuezhi Wu Baoguo Fan Liangliang Liao Jiachang Wang Yunhan Xiao | 2009 | Particuology2009，7，4： | 3 |
| 18 | Magnetostrictive properties and detection efficiency of TbDyFe/FeCo composite materials for nondestructive testing显示文摘In order to develop a highly sensitive material for nondestructive testing(NDT),(Tb_(0.3) Dy_(0.7))Fe_(1.95) thin films were deposited on FeCo substrates at room temperature by magnetron sputtering and annealed.The magnetostrictive properties and the detection efficiency of the composite films were investigated.Results demonstrate that the detection efficiency roughly shows regular consistency with the magnetostrictive strain of the TbDyFe films. Heat treatment has a great effect on the crystalline state and the magnetostrictive strain of the composite materials. The as-deposited(Tb_(0.3) Dy_(0.7))Fe_(1.95) films are amorphous, and the saturation magnetostriction(ls) is only 90 ppm. However, the nanostructured crystalline REFe2 is partially separated out in amorphous matrix after annealing at 600C for 1 h, and the ls increases to 265 ppm. Simultaneously, the detection efficiency of the composite materials is obviously improved compared to that of the as-deposited films. The detection signal of traditional FeCo strip is0.4 V at the excitation power of 1.0 P and frequency of 128 kHz and that of the strip increases significantly by depositing one layer of(Tb_(0.3) Dy_(0.7))Fe_(1.95) film. The detection signal of the composite material annealed at 600C is the best, even reaching saturation value of 2.5 V(1.0 P, 128 kHz). The results may provide us with a method for preparing new materials for NDT. | Liangliang Zhu Kuoshe Li Yang Luo Dunbo Yu Zilong Wang Guiyong Wu Jiajun Xie Zhifeng Tang | 2019 | Journal of Rare Earths2019，37，2： | 3 |
| 19 | Hydrogen sulfide removal by catalytic oxidative absorption method using rotating packed bed reactor显示文摘Using catalytic oxidative absorption for H_2S removal is of great interest due to its distinct advantages. However,traditional scrubbing process faces a great limitation in the confined space. Therefore, there is an urgent demand to develop high-efficiency process intensification technology for such a system. In this article, H_2S absorption experimental research was conducted in a rotating packed bed(RPB) reactor with ferric chelate absorbent and a mixture of N_2 and H_2S, which was used to simulate natural gas. The effects of absorbent p H value, gas–liquid ratio, gravity level of RPB, absorption temperature and character of the packing on the desulfurization efficiency were investigated. The results showed that H_2S removal efficiency could reach above 99.6% under the most of the experimental condition and above 99.9% under the optimal condition. A long-time continuous experiment was conducted to investigate the stability of the whole process combining absorption and regeneration. The result showed that the process could well realize simultaneous desulfurization and absorbent regeneration, and the H_2S removal efficiency kept relatively stable in the whole duration of 72 h. It can be clearly seen that high gravity technology desulfurization process, which is simple, high-efficiency, and space intensive, has a good prospect for industrial application of H_2S removal in confined space. | Liangliang Zhang Shuying Wu Zuozhong Liang Hong Zhao Haikui Zou Guangwen Chu | 2017 | Chinese Journal of Chemical Engineering2017，25，2： | 3 |
| 20 | A kind of double-sided porous anodic alumina membrane fabricated with the three-step anodic oxidation method显示文摘The porous anodic alumina membranes(PAAMs)have been successfully used as templates for the fabrication of functional nano-materials due to their outstanding regularity and physicochemical properties.In this paper,a transparent double-sided anodic alumina membrane with ultra-thin aluminum substrate was fabricated with the three-step anodic oxidation method in the oxalic acid electrolyte.The characters such as the top-surface morphology,membrane thickness,and depth of nanopores of this three-layer(Al2O3-Al-Al2O3)sandwiched nano-structure were controllable through regulating the main anodic oxidation conditions,e.g.,anodic oxidation time of various steps,coating remove process.The experiments data revealed that the aluminum substrate is exponential declined with the oxidation time when it was approximately reduced by a few micrometers.This new double-sided anodic alumina membrane can be used as the high-quality functional field emission materials and templates. | ZHANG Chen WANG KaiGe GAO ZeYang WU JunJun REN JunYing ZHANG LiangLiang GU ChangZhi BAI JinTao | 2014 | Science China(Technological Sciences)2014，57，2： | 2 |
