| 1 | Preparation of ternary Cr_2 O_3-SiC-TiO_2 composites for the photocatalytic production of hydrogen显示文摘Novel ternary Cr 2 O 3 -SiC-TiO 2 composites were synthesized by implanting Cr 3+ into SiC-TiO 2 via sol-gel and impregnation approaches. The results from X-ray diffraction, scanning electron microscopy and trans- mission electron microscopy show that the Cr 3+ species were doped onto the surface of the SiC-TiO 2 carrier. The diffuse reflectance ultraviolet-visible absorption spectra revealed that the absorption edges of the ternary Cr 2 O 3 -SiC-TiO 2 composites were gradually shifted red with increasing chromium content. The luminescence intensities of the composites decreased with increasing doped Cr 3+ content due to the reduction in the number of recombination sites of electron-hole pairs. The ternary Cr 2 O 3 -SiC-TiO 2 com- posites showed high hydrogen-producing activities, which probably results from the formation of donor levels of the Cr 3+ species in the forbidden band of the SiC semiconductor. | Yaojun Zhang Yong Xu Tuo Li Yachao Wang | 2012 | Particuology2012,10,1: | 8 |

| 3 | Computer-Assisted Detection of Colonic Polyps Using Improved Faster R-CNN显示文摘The deficiencies of existing polyp detection methods remain:i)They primarily depend on the manually extracted features and require considerable amounts of preprocessing.ii)Most traditional methods cannot specify the location of the polyps in colonoscopy images,especially for the polyps with variable size.In order to derive the improvement and lift the accuracy,we propose a novel and scalable detection algorithm based on deep neural networks-an improved Faster Regionbased Convolutional neural networks(Faster R-CNN)-by increasing the fusion of feature maps at different levels.It can be employed to detect and locate polyps,and even achieve a multi-object task for polyps in the future.The experimental consequences demonstrate that the best version among improved algorithms achieves 97.13%accuracy on the CVC-ClinicDB database,overtaking the previous methods. | LI Jiangyun ZHANG Jie CHANG Dedan HU Yaojun | 2019 | Chinese Journal of Electronics2019,28,4: | 6 |
| 4 | Effects of sediment parameters on the low frequency acoustic wave propagation in shallow water显示文摘The integral expression for acoustic field due to a point source in shallow waterwhile sediment is either a liquid or a solid is derived. The synthetic full waveforms are simulatedusing real axis integration and FFF method. The effects of the seabed sediment parametersand center frequency of the source on the low frequency acoustic wave propagation in shallowwater are investigated. The conclusion is that the wave groups received in far field are thoseof the mode waves of the source center frequency. The possibility for inversely deducing thecompressional and shear sound speeds of sediment using the least square optimum through themeasured group velocities of a selected mode at different frequencies is discussed. | LI Zhenglin WANG Yaojun(The State Key Laboratory of Modern Acoustics, Nanjing University Nanjing 210093)MA Li GAO Tianfu(Institute of Acoustics, Academia Silica Beijing 100080) | 2000 | Chinese Journal of Acoustics2000,19,3: | 5 |
| 5 | Evaluating transit operator efficiency:An enhanced DEA model with constrained fuzzy-AHP cones显示文摘This study addresses efforts to comb the Analytic Hierarchy Process(AHP) with Data Envelopment Analysis(DEA) to deliver a robust enhanced DEA model for transit operator efficiency assessment.The proposed model is designed to better capture inherent preferences information over input and output indicators by adding constraint cones to the conventional DEA model.A revised fuzzy-AHP model is employed to generate cones,where the proposed model features the integration of the fuzzy logic with a hierarchical AHP structure to:1) normalize the scales of different evaluation indicators,2) construct the matrix of pairwise comparisons with fuzzy set,and 3) optimize the weight of each criterion with a nonlinear programming model.With introduction of cone-based constraints,the new system offers accounting advantages in the interaction among indicators when evaluating the performance of transit operators.To illustrate the applicability of the proposed approach,a real case in Nanjing City,the capital of China's Jiangsu Province,has been selected to assess the efficiencies of seven bus companies based on 2009 and 2010 datasets.A comparison between conventional DEA and enhanced DEA was also conducted to clarify the new system's superiority.Results reveal that the proposed model is more applicable in evaluating transit operator's efficiency thus encouraging a boarder range of applications. | Xin Li Yue Liu Yaojun Wang Zhigang Gao | 2016 | Journal of Traffic and Transportation Engineering(English Edition)2016,3,3: | 4 |
| 6 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021,41,12: | 3 |

| 11 | Integrating PCR-free amplification and synergistic sensing for ultrasensitive and rapid CRISPR/Cas12a-based SARS-CoV-2 antigen detection显示文摘Antigen detection provides particularly valuable information for medical diagnoses;however,the current detection methods are less sensitive and accurate than nucleic acid analysis.The combination of CRISPR/Cas12a and aptamers provides a new detection paradigm,but sensitive sensing and stable amplification in antigen detection remain challenging.Here,we present a PCR-free multiple trigger dsDNA tandem-based signal amplification strategy and a de novo designed dual aptamer synergistic sensing strategy.Integration of these two strategies endowed the CRISPR/Cas12a and aptamer-based method with ultra-sensitive,fast,and stable antigen detection.In a demonstration of this method,the limit of detection was at the single virus level(0.17 fM,approximately two copies/μL)in SARS-CoV-2 antigen nucleocapsid protein analysis of saliva or serum samples.The entire procedure required only 20 min.Given our system’s simplicity and modular setup,we believe that it could be adapted reasonably easily for general applications in CRISPR/Cas12a-aptamer-based detection. | Xiangxiang Zhao Zhengduo Wang Bowen Yang Zilong Li Yaojun Tong Yuhai Bi Zhenghong Li Xuekui Xia Xiangyin Chen Lixin Zhang Weishan Wang Gao-Yi Tan | 2021 | Synthetic and Systems Biotechnology2021,6,4: | 1 |

| 13 | Climate-driven acceleration of glacier mass loss on global and regional scales during 1961–2016显示文摘During the past decades, glacier mass loss is becoming increasingly significant worldwide but knowledge about the acceleration is still limited despite its potentially profound impacts on sea level rise, water resources availability and glacial hazards. In this study, we analyzed the acceleration of glacier mass loss based on in-situ measurements and on the latest compilation dataset of direct and geodetic observations for the period 1961–2016. The results showed that the rate of glacier mass loss has increased worldwide during the past decades. At the global scale, the rate of glacier mass loss has been accelerating at 5.76±1.35 Gt a-2 as well as 0.0074±0.0016 m w.e.a-2 on mass balance(refer to the area-averaged mass change value) during the whole period. At regional scales, for mass change rate, the heavily glacierized regions excluding Antarctic and Subantarctic exhibited a larger acceleration compared to other regions. The highest acceleration of mass change was found in Alaska glaciers(1.33±0.47 Gt a-2) over the full period. As for mass balance, high acceleration occurred on the regions with small glaciers as well as on the heavily glacierized regions. Central Europe exhibited the highest acceleration(0.024±0.0088 m w.e.a-2) during 1961–2016. High level of consistency between the acceleration and temperature implies that climate warming had a significant effect on the accelerating of glacier mass loss. Moreover, acceleration of the contribution from the Greenland ice sheet(0.028 to0.070 mm a-2) and Antarctic ice sheet(0.023 to 0.058 mm a-2) to sea level rise exceeds acceleration of the contribution from global glaciers(0.019±0.013 mm a-2). These results will improve our understanding of the glacier retreat in response to climate change and provide critical information for improving mitigation strategies for impacts that may be caused by glacier melting. | Yaojun LI Yongjian DING Donghui SHANGGUAN Fengjing LIU Qiudong ZHAO | 2021 | Science China Earth Sciences2021,64,4: | 1 |

| 18 | The effects of bonding conditions on the propagation of acoustic waves along a cased borehole显示文摘Based on the wave equations in cylindrically layered structures and boundary conditions, the frequency equation for axisymmetric guided waves and the expression for sound fields in a cased borehole excited by a monopole or multipole source have been derived. The synthetic full waveforms excited by the monopole and dipole source are simulated using a real axis integration and FFT method. According to the axisymmetric guided wave modes, the synthetic full waveforms and the effects of the interface conditions on the sound field in a cased borehole have been analyzed and studied respectively. Numerical results indicate that it may be difficult to distinguish well bonded, poorly bonded or unbonded intermediate layer between the steel pipe and formation if only using a monopole source or dipole source. To properly estimate the case boundary conditions, a combination of monopole source logging with dipole source logging is suggested. | LI Zhenglin, DU Guangsheng, WANG Yaojun (The State Key Laboratory of Modern Acoustics, Nanjing University Nanjing 210093) | 2001 | Chinese Journal of Acoustics2001,20,3: | 1 |
