| 1 | Distribution and significance of C~_(40) alkanes in the extracts of Cretaceous source rocks from the Songliao Basin显示文摘Source rock extracts and crude oils from the Songliao Basin were analyzed by high-temperature gas chromatography (HTGC), gas chromatography-mass spectrometry (HTGC-MS) and gas chromatography-isotope ratio-mass spectrometry (GC-IRMS), for high molecular-weight alkanes. The distributions of n-alkanes in the Nenjiang Formation extracts are in the C14―C63 range; a bimodal distribution occurs in the C-21 and C21―40 regions. The C30―C37 n-alkanes are accompanied by C29―C35 hopanes, whereas the high molecular-weight C45―C47 n-alkanes co-occur with abundant isoalkanes, alkylcyclohexanes and alkylcyclopentanes. The high δ 13C values of the n-alkanes and the microscopic maceral compositions indicate a highly diversified organic source input for the Nenjiang Formation source rocks, ranging from aquatic plants, blue alge-bacteria, to land plant material. In contrast, n-alkanes in the rock extracts of the Qingshankou Formation are characterized by a single modal distribution, with relatively low abundances of C29―C35 hopanes, but high molecular-weight isoalkanes, alkylcyclohexanes and alkylcyclopentanes. The relatively low δ 13C values of C22―C44 n-alkanes and organic material compositions indicate that the source rocks in the Qingshankou Formation contain dominantly type I algal organic matter. The relative abundance of C+40 compounds in source rocks changes little at low maturity stage, but decreases drastically at higher maturity levels, with a concurrent reduction in the odd/even carbon predominance. In crude oils, in contrast, the relative abundance of C+40 compounds appears to relate closely with the oil source and oil viscosity. | FENG ZiHui FANG Wei ZHANG JuHe LI ZhenGuang HUANG ChunYan WANG Xue ZHAO QinLing HUO QiuLi | 2007 | Science China Earth Sciences2007，50，10： | 10 |

| 3 | Characterizing robustness and sensitivity of convolutional neural networks for quantitative analysis of mitochondrial morphology显示文摘Background:Quantitative analysis of mitochondrial morphology plays important roles in studies of mitoehondrial biology.The analysis depends critically on segmentation of mitochondria,the image analysis process of extracting mitochondrial morphology from images.The main goal of this study is to characterize the performance of eonvolutional neural networks (CNNs)in segmentation of mitochondria from fluorescence microscopy images. Recently,CNNs have achieved remarkable success in challenging image segmentation tasks in several disciplines.So far,however,our knowledge of their performance in segmenting biological images remains limited.In particular,we know little about their robustness,which defines their capability of segmenting biological images of different conditions,and their sensitivity,which defines their capability of detecting subtle morphological changes of biological objects. Methods:We have developed a method that uses realistic synthetic images of different conditions to characterize the robustness and sensitivity of CNNs in segmentation of mitochondria.Using this method,we compared performance of two widely adopted CNNs:the fully convolutional network (FCN)and the U-Net.We further compared the two networks against the adaptive active-mask (AAM)algorithm,a representative of high-performance conventional segmentation algorithms. Results:The FCN and the U-Net consistently outperformed the AAM in accuracy,robustness,and sensitivity,often by a significant margin.The U-Net provided overall the best performance. Conclusions:Our study demonstrates superior performance of the U-Net and the FCN in segmentation of mitochondria.It also provides quantitative measurements of the robustness and sensitivity of these networks that are essential to their applications in quantitative analysis of mitochondrial morphology. | Xiaoqi Chai Qinle Ba Ge Yang | 2018 | Frontiers of Electrical and Electronic Engineering in China2018，6，4： | 3 |
| 4 | Robust design and analysis of a conformal expansion nozzle with inverse-design idea显示文摘This paper examines robust optimization design and analysis of a conformal expansion nozzle of flying wing Unmanned Aerial Vehicle(UAV) with the inverse-design idea.In view of flow features and stealth constraints, the inverse-design idea is described and the uncertainty-based robust design model is presented.A robust design system employs this model to combine deterministic optimization and robust optimization and is applied into design of a conformal expansion nozzle.The results indicate that design optimization can conform to the anticipation of the inversedesign idea and significantly improve the aerodynamic performance that meet the requirement of 6σ.The present method is a feasible nozzle design strategy that integrates robust optimization and inverse-design. | Wenbiao GAN Xiaocui ZHANG Tielin MA Qinling ZHANG Wu YUAN | 2018 | Chinese Journal of Aeronautics2018，31，1： | 3 |

| 6 | Analysis of thermohaline and current distribution characteristics of Zhejiang and Fujian waters in summer显示文摘This paper analyzed the distribution of thermohaline and circulation characteristics of Zhejiang and Fujian waters,based on the cross-sectional thermohaline data and on current data (up to 30 d duration) at fixed-point moorings,collected in the summer of 2006.We also performed low-pass filtering and spectrum analysis on the mooring submersible buoy data.Based on that analysis,we discussed the characteristics of low frequency currents and time-variations in these waters.The main conclusions are as follows.(1) There is a low salinity pinnate area near the Hangzhou Bay in summer,and outside the low salinity area,an obvious salinity front is present from surface to bottom near 123 E.There is also a temperature front below the surface at a corresponding position.(2) Bottom water of the Taiwan Warm Current comes from the subsurface of Kuroshio.(3) The direction of low frequency current at fixed anchor stations is N-NE or S,which mainly depends on the interaction of control currents in this waters.(4) Significant spectral peaks at all mooring stations are typically semidiurnal and diurnal tides.Semidiurnal tidal waves are the main ones in these waters,and have more energy closer to the shore.(5) Significant energy spectral peaks of middle period (3 to 8 d) of currents are responses to weather frequency.(6) Significant energy spectral peaks of long periods at the surface or bottom are probably responses to seasonal wind or bottom friction,while,the long period peaks of other depths can reflect cyclical changes of interactions between currents.We conclude that the pulsation period of the Taiwan Warm Current in these waters is 10-17 d. | DU Panjun ZHANG Hui XIAO Wenjun KANG Xing GUAN Qinle | 2011 | Acta Oceanologica Sinica2011，30，5： | 3 |
| 7 | Analysis of characteristics of time-frequency correlations between runoff,tidal range and salinity in the Changjiang Estuary显示文摘Power spectrum and cross-wavelet transform analysis was adopted to study the time-frequency characteristics and multiscale correlations between runoff,tidal range and salinity in the Changjiang Estuary based on the runoff data collected at the Datong Station,the tidal range measured at the Baozhen Station,and the salinity at the Baogang Station from 2008 to 2009.The variations of the salinity showed significant periodicity at scales of 2-3,7-8,14-15 and 26-30 d.The correlation between the salinity and the runoff and the tidal range were found to be significantly related to shock at scales of 5-7,14-15,26-30 d and 0.5 a.The correlation between the runoff and the salinity was mainly in the same phase,while the correlation between the tidal range and the salinity was in the antiphase.Different frequency bands were related to different degrees,and their relevance increased as the resonance frequency decreased.In addition,changes of the seasonal runoff were obvious.Specifically,a point of discontinuity was reached in early June with a cycle of 7-8 d,which coincided with the periodicity of plum rains in the Changjiang-Huaihe region.High-frequency changes (8-16 d period) of the salinity corresponded to the time domain in January-April 2008,February-April 2009 and October-December 2009 and exhibited an approximately 0.5 a (184 d) long frequency oscillation.Short-period changes were found to be stronger than long-period changes.Cross-wavelet transforms for the salinity,the runoff and the tidal range revealed local features in the time domain,while the significant levels of different periodic oscillations were observed in the frequency domain.The correlation characteristics of the salinity and the runoff were significant in the 80-90 d frequency domain,indicating that the major impact of the runoff on the salinity was reflected in seasonal changes.The tidal range on the small scale of 14-15 and 30-32 d was more obvious than the runoff. | FEI Yuejun XU Lili DU Panjun GUAN Qinle KANG Xing XIAO Wenjun | 2011 | Acta Oceanologica Sinica2011，30，5： | 3 |
