| 1 | Formation of Natural Bitumen and its Implication for Oil/gas Prospect in Dabashan Foreland显示文摘Natural bitumen is the evolutionary residue of hydrocarbon of sedimentary organic matter.Several kinds of bitumen with different occurrences,including bitumen in source rock,migration bitumen filled in fault,oil-bed bitumen and paleo-reservoir bitumen,are distributed widely in the Dabashan foreland.These kinds of bitumen represent the process of oil/gas formation,migration and accumulation in the region.Bitumen in source rock filled in fractures and stylolite and experienced deformation simultaneously together with source rock themselves.It indicated that oil/gas generation and expelling from source rock occurred under normal buried thermal conditions during prototype basin evolution stages prior to orogeny.Occurrences of bitumen in source rock indicated that paleo-reservoir formation conditions existed in the Dabashan foreland.Migration bitumen being widespread in the fault revealed that the fault was the main channel for oil/gas migration,which occurred synchronously with Jurassic foreland deformation.Oil-bed bitumen was the kind of pyrolysis bitumen that distributed in solution pores of reservoir rock in the Dabashan foreland depression,the northeastern Sichuan Basin.Geochemistry of oil-bed bitumen indicated that natural gas that accumulated in the Dabashan foreland depression formed from liquid hydrocarbon by pyrolysis process.However,paleo-reservior bitumen in the Dabashan forleland was the kind of degradation bitumen that formed from liquid hydrocarbon within the paleo-reservior by oxidation,alteration and other secondary changes due to paleo-reservior damage during tectonics in the Dabashan foreland.In combination with the tectonic evolution of the Dabashan foreland,it is proposed that the oil/gas generated,migrated and accumulated to form the paleo-reservoir during the Triassic Indosinian tectonic movement.Jurassic collision orogeny,the Yanshan tectonic movement,led to intracontinental orogeny of the Dabashan area accompanied by geofluid expelling and paleo-reservoir damage in the Dabashan foreland.The present work proposed that there is liquid hydrocarbon exploration potential in the Dabashan foreland,while there are prospects for the existence of natural gas in the Dabashan foreland depression. | LI Rongxi DONG Shuwen ZHANG Xue ZHU Ruijing | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 7 |

| 3 | Adaptive Pseudo Inverse Control for a Class of Nonlinear Asymmetric and Saturated Nonlinear Hysteretic Systems显示文摘This paper aims at eliminating the asymmetric and saturated hysteresis nonlinearities by designing hysteresis pseudo inverse compensator and robust adaptive dynamic surface control(DSC)scheme.The'pseudo inverse'means that an on-line calculation mechanism of approximate control signal is developed by applying a searching method to the designed temporary control signal where the true control signal is included.The main contributions are summarized as:1)to our best knowledge,it is the first time to compensate the asymmetric and saturated hysteresis by using hysteresis pseudo inverse compensator because the construction of the true saturated-type hysteresis inverse model is very difficult;2)by designing the saturated-type hysteresis pseudo inverse compensator,the construction of true explicit hysteresis inverse and the identifications of its corresponding unknown parameters are not required when dealing with the saturated-type hysteresis;3)by combining DSC technique with the tracking error transformed function,the'explosion of complexity'problem in backstepping method is overcome and the prespecified tracking performance is achieved.Analysis of stability and experimental results on the hardware-inloop platform illustrate the effectiveness of the proposed adaptive pseudo inverse control scheme. | Xiuyu Zhang Ruijing Jing Zhiwei Li Zhi Li Xinkai Chen Chun-Yi Su | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，4： | 4 |
| 4 | Recovery of neodymium,dysprosium,and cobalt from NdFeB magnet leachate using an unsymmetrical dialkylphosphinic acid extractant,INET-3显示文摘Rare earths (REs) and Co are critical strategic resources.Their recovery is crucial for ensuring that their supplies are adequate and for reducing environmental pollution.End-of-life NdFeB magnets are important secondary RE sources.The separation of Dy,Nd,and Co from NdFeB leachate using a relatively new extractant (2,3-dimethylbutyl)(2,4,4’-trimethylpentyl)phosphinic acid (INET-3),was investigated in this study.The separation parameters,such as equilibrium pH,phase ratio,INET-3 concentration,and number of counter-current extraction stages,were optimised.The results show that INET-3 can separate Dy,Nd,and Co efficiently.For the preferential extraction of Dy from synthetic iron-free NdFeB leachate,the optimum equilibrium pH is 2.60.Under this condition,separation of Dy from the leachate requires four counter-current extraction stages at A/O (volume ratio of aqueous to organic)=1:2.This is demonstrated by a simulated four-stage counter-current extraction process.At equilibrium pH=2.52and A/O=1:2,98%of Dy is recovered with 95%purity.As to the subsequent separation of Nd from the leachate,nearly 100%is recovered with 99%purity through a simulated three-stage counter-current extraction process at equilibrium pH=5.33 and A/O=1:1.Approximately 95%of Co remains in the raffinate with 99.98%purity. | Zhengyu Liu a Jiaming Wu a Xinyu Liu Wen Wanga Ziwei Li Ruijing Xu Yue Ding Junlian Wang | 2020 | Journal of Rare Earths2020，38，10： | 3 |
| 5 | Fast synthesis of monodisperse TiO_2 submicrospheres via a modified sol-gel approach显示文摘Monodisperse titania glycolate submicrospheres were synthesized by a modified sol-gel route, in which ultrasonic treatment was introduced to improve the reaction efficiency. The as-prepared products were characterized by means of Fourier transform infrared spectrum (FT-IR), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results indicate that the as-prepared products are titania glycolate submicrospheres with diameters of 230-330 nm. The average particle diameter is estimated to be about 280 nm. Ultrasonic treatment has an important influence on the morphology of the produced titania glycolates. After calcination at 450°C for 2 h, these titania glycolates were completely converted into anatase TiO2. The morphology of TiO2 particles was well reserved during the calcination process except for a reduction of 18% in the average particle size. | WANG Hong'en LI Bo YAN Zaoxuea LU Zhouguang CHENG Ruijing QIAN Donga | 2008 | Rare Metals2008，27，1： | 2 |
| 6 | Comparison of Four Forward Models for Breast Imaging in Ultrasound Computed Tomography显示文摘Ultrasound computed tomography(USCT)is considered to have great potential for breast cancer screening.Compared with ray-based methods,Waveform inversion(WI)methods obtain high spatial resolution images because they consider higher-order diffraction effects.For the WI method,considering more properties of the medium in a forward model can estimate more accurate images.However,longer reconstruction time is required.Therefore,to reduce the reconstruction time,three hypotheses are set in this work to develop the medium under different conditions.We compare the reconstructed images using the four forward models to analyze the effects of the various considered medium properties,which include the sound speed,density of the medium,acoustic absorption and dispersion.To reduce the difficulty of hardware manufacturing,a square border ultrasonic transducer array is adopted in the USCT data acquisition system.Penalized leastsquares optimization problems are constructed to obtain numerical solutions of the sound speed and bulk modulus distributions.The reconstruction of the bulk modulus makes the reconstructed sound speed images more accurate.Computer simulations are conducted to compare reconstructed images using the four forward models under different noise conditions.A numerical breast phantom is used to evaluate the performance.The results suggest that for breast imaging,the forward model(which only considers the heterogeneous sound speed)is a compromise option between image accuracy and computational time. | LI Ruijing CHEN Houjin PENG Yahui LI Jupeng | 2019 | Chinese Journal of Electronics2019，28，4： | 2 |
| 7 | Numerical Study of Square Border Ultrasonic Transducer Element Arrays for Breast Imaging in Ultrasound Computed Tomography with Waveform Inversion Method显示文摘Ultrasound computed tomography (USCT) is a promising approach for early breast cancer screening. Existing studies that estimate breast images using Waveform inversion (WI) methods utilize a Circular ultrasonic transducer element array (CUTA) to collect the measurement data. However, very accurate transducer element positioning and directivity are required for signal calibration in the hardware system of these studies, thereby causing difficulties in hardware manufacturing. The purpose of this study is to estimate high-resolution USCT images using a WI method with a Square border ultrasonic transducer element array (SUTA), which reduces the difficulty of hardware manufacturing and creates accurate correspondence between the continuous and discrete forms of the transducer element positions. Therefore, in this study, an SUTA is adopted to collect the measurement data of breast imaging using the WI method. A penalized least-squares optimization problem is constructed to obtain the numerical solution of a sound speed distribution. Computer simulations are conducted to compare images reconstructed from the measurement data that are collected using an SUTA and a CUTA. The performance is evaluated using a numerical breast phantom. Results suggest that the biases of the images reconstructed are less than 1% with the evenly distributed SUTA and 1% with the CUTA, under a noise condition. | LI Ruijing CHEN Houjin PENG Yahui LI Jupeng | 2019 | Chinese Journal of Electronics2019，28，5： | 2 |

| 15 | The point of no return and pectoral angle of Japanese anchovy(Engraulis japonicus) larvae during growth and starvation显示文摘At a temperature of 23.0~24.8℃,the mixed feeding of Japanese anchovy larvae was initiated 24 h before the yolk-sac was exhausted.The point of no return(PNR) was reached on the 6th day after hatching.On the 4th day after hatching,the pectoral angle appeared in both fed and unfed anchovy larvae although it was more evident and sharper in the starved and the PNR stage larvae than in the fed ones.According to observations of larvae collected in the sea,the pectoral angles were evident not only in the larvae of 3.62~7.44 mm in standard length,but also in the larvae of 2.70 mm in standard length with remnants of yolk.The pectoral angles became diffuse when the larvae reached 7.84 mm and vanished at 9.86 mm.The pectoral angle cannot be used as a criterion to distinguish healthy from starving larvae. | WAN Ruijing LI Xiansen ZHUANG Zhimeng JOHANNESSEN Arne | 2007 | Acta Oceanologica Sinica2007，26，5： | 1 |

| 17 | Evaluation of Bacillus sp. MZS10 for decolorizing Azure B dye and its decolorization mechanism显示文摘To evaluate decolorization and detoxification of Azure B dye by a newly isolated Bacillus sp. MZS10 strain, the cultivation medium and decolorization mechanism of the isolate were investigated. The decolorization was discovered to be dependent on cell density of the isolate and reached 93.55%(0.04 g/L) after 14 hr of cultivation in a 5 L stirred-tank fermenter at 2.0 g/L yeast extract and 6.0 g/L soluble starch and a small amount of mineral salts. The decolorization metabolites were identified with ultra performance liquid chromatography-tandem mass spectroscopy(UPLC-MS). A mechanism for decolorization of Azure B was proposed as follows: the C=N in Azure B was initially reduced to –NH by nicotinamide adenine dinucleotide phosphate(NADPH)-dependent quinone dehydrogenase, and then the –NH further combined with –OH derived from glucose to form a stable and colorless compound through a dehydration reaction. The phytotoxicity was evaluated for both Azure B and its related derivatives produced by Bacillus sp. MZS10 decolorization, indicating that the decolorization metabolites were less toxic than original dye. The decolorization efficiency and mechanism shown by Bacillus sp. MZS10 provided insight on its potential application for the bioremediation of the dye Azure B. | Huixing Li Ruijing Zhang Lei Tang Jianhua Zhang Zhonggui Mao | 2014 | Journal of Environmental Sciences2014，26，5： | 1 |

| 20 | EBV-induced human CD8^(+) NKT cells synergize CD4^(+) NKT cells suppressing EBV-associated tumors upon induction of Th1 bias显示文摘The authors inadvertently published histograms in the fourth panel to the right in both rows of Figure 4c that were actually the data of CD81 NKT cells from EBV-exposed CD8^(+)NKT cell-transferred,or EBV-exposed CD41 and CD81 NKT-trans-ferred hu-thym-SCID chimeras.The corrected figure included here contains the histograms that correctly represent the data of T cells from EBV-exposed CD41 and CD81 NKT-trans-ferred hu-thym-SCID chimeras.Since the fourth panels to the right in both rows of Figure 4c show the cellular proliferation using the CFSE labeling technique,the histogram substitutions do not alter the conclusions that were drawn from the original data.The authors would like to apologize for their mistake. | Wei Xiao Li Li Rui Zhou Ruijing Xiao Yujuan Wang Xiang Ji Mengjun Wu Lan Wang Wei Huang | 2011 | Cellular & Molecular Immunology2011，8，4： | 0 |
