1High precision topographic data on Lop Nor basin's Lake 'Great Ear' ? and the timing of its becoming a dry salt lake显示文摘High precision elevation measurements using DGPS were carried out along three representative tran- sects for the 'Great Ear' area, a dry salt lake within the Lop Nor basin. Results indicate that the Lop Nor basin is only 5.2 m deep and its lowest point occurs at the center of the 'Great Ear'. In addition, the basin is asymmetric - steeper in the southwest (0.19‰) and gentler in the northeast (0.09‰). Points along the same 'Great Ear' ring were found to have an identical elevation value, but different when from different ones (lower towards the center). The spacing of the 'Great Ear' rings was found to be closely related with the surface steepness. The closer the 'Great Ear' rings are spaced, the steeper the ground surface, and vice versa. These findings support the argument that the 'Great Ear' rings are the former shoreline trails left behind by Lop Nor water during the last few episodes of recession towards its total dry up. A comprehensive analysis of the high precision elevation data, historical accounts, aerial and satellite photographs and imagery, and official topographic maps of the study area suggests that the 'Great Ear' area in the Lop Nor basin was incorrectly mapped as being covered by a great body of water on the 1963 topographic maps. A re-interpretation of the 1958 aerial photographs and newer remote sensing imagery indicated that the 'Great Ear' ring structure was already in place in 1958 and it continued to appear on the subsequent remote sensing data without any major changes. It is estimated that lake water in the 'Great Ear' area of the Lop Nor basin disappeared between the late 1930s and early 1940s.LI BaoGuo MA LiChun JIANG PingAn DUAN ZengQiang SUN DanFeng QIU HongLie ZHONG JunPing WU HongQi 2008Chinese Science Bulletin2008,53,6:11

3Performance and role of N-acyl-homoserine lactone(AHL)-based quorum sensing(QS) in aerobic granules显示文摘The present study investigated the relationship between N-acyl-homoserine lactone(AHL)-based quorum sensing(QS) and the physico-chemical properties of aerobic granules.Stable mature granules were observed in SBR2 and SBR3 with average diameters of 0.96,and1.49 mm,respectively. The sludge densities of aerobic granules in SBR2 and SBR3 were1.0246,and 1.0201 g/mL,respectively,which were higher than that of flocculent sludge in SBR1(1.0065 g/mL). The results showed that the activity of AHL-based QS in SBR2 and SBR3 amounted to 2.4- and 2.1-fold induction,however,that in SBR1 with flocculent sludge was1.6-fold induction. In addition,the results also showed that the activity of AHL-based QS in the three reactors rose in the feast condition,and then dropped with the consumption of substrate. However,the activity of AHL-based QS in these three reactors recovered again in prolonged starvation. Furthermore,the results showed that the enhancement of AHL-based QS favored the extracellular polymeric substance production of microorganisms in activated sludge. Thus,it could be concluded that aerobic granules showed higher AHL-based QS than flocculent sludge,which resulted from the higher sludge density of aerobic granules than flocculent sludge. AHL-based QS was related to the metabolism energy in the feast condition; however,in prolonged starvation,microorganisms would emit more AHL-like molecules to protect themselves to resist starvation. Moreover,the enhancement of AHL-based QS favored the EPS component productivity of the microorganisms in activated sludge,which contributed to maintain the aerobic granular structure.Yaochen Li Junping Lv Chen Zhong Wen Hao Yaqin Wang Jianrong Zhu 2014Journal of Environmental Sciences2014,26,8:6

6Automated retinal layer segmentation in optical coherence tomography images with intraretinal fluid显示文摘We propose a novel retinal layer segmentation method to accurately segment 10 retinal layers in optical coherence tomography(OCT)images with intraretinal fluid.The method used a fan filter to enhance the linear information pertaining to retinal boundaries in an OCT image by reducing the effect of vessel shadows and fluid regions.A random forest classifier was employed to predict the location of the boundaries.Two novel methods of boundary redirection(SR)and similarity correction(SC)were combined to carry out boundary tracking and thereby accurately locate retinal layer boundaries.Experiments were performed on healthy controls and subjects with diabetic macular edema(DME).The proposed method required an average of 415 s for healthy controls and of 482 s for subjects with DME and achieved high accuracy for both groups of subjects.The proposed method requires a shorter running time than previous methods and also provides high accuracy.Thus,the proposed method may be a better choice for small training datasets.Luquan Wang Xiaowen Li Yong Chen Dingan Han Mingyi Wang Yaguang Zeng Junping Zhong Xuehua Wang Yanhong Ji Honglian Xiong Xunbin Wei 2022Journal of Innovative Optical Health Sciences2022,15,3:0
7CONTRAST-ENHANCED PHOTOACOUSTIC IMAGING USING INDOCYANINE GREEN-CONTAINING NANOPARTICLES显示文摘Contrast agents are attracting a great deal of attention in photoacoustic inaging.Here weintroduce an exogenous contrast agent that provides high photoacoustic signal amplitude at thenear-infrared wavelength._Our_agents consist_of Indocyanine green(ICG)and phospholi-pid-polyethylene glycol(PL-PEG),entitled ICG-PL-PEG nanoparticles,These nanoparticleshave overcome numerous limitations of ICG,such as poor aqueous stability,concentration-dependent aggregation and lack of target specificity.ICG-PL-PEG nanoparticles are bio-compatible and relatively nontoxic.All the components of ICG-PL-PEG nanoparticles havebeen approved for human use.Upon pulsed laser irradiation,the nanoparticles are more eficient inproducing photoacoustic waves than ICG alone.The results showed that ICG-PL-PEG nano-particles act as good contrast agents for photoacoustic imaging.These unique ICG-PL-PEGnanoparticles have great potential in clinical applications.JUNPING ZHONG SIHUA YANG 2014Journal of Innovative Optical Health Sciences2014,7,1:0
8Detection of cells by flow cytometry:Counting,imaging,and cell classification显示文摘The study of circulating cells in the blood stream is critical,as it covers many felds of biomed-icine,including immunology,cell biology,oncology,and reproductive medicine.In-viuo flowcytometry(IVFC)is a new tool to monitor and count cells in real time for long durations in theirnative biological environment.This review describes two main categories of IVFC,ie.,labeledand label-free IVFC.It focuses on label-free IVFC and introduces its technological developmentand related biological applications.Because cell recognition is the basis of flow cytometrycounting,this review also describes various methods for the classification of unlabeled cells,including the latest machine learning-based technologies.Yingsi Yu Yimei Zheng Caizhong Guan Min Yi Yunzhao Chen Yaguang Zeng Honglian Xiong Xuehua Wang Junping Zhong Wenzheng Ding Mingyi Wang Xunbin Wei 2023Journal of Innovative Optical Health Sciences2023,16,3:0
