Open Journal of Depression (OJD) , 2014, DOI: 10.4236/ojd.2014.35022
Abstract: Objective: Both of selective serotonin reuptake inhibitors (SSRIs) and estrogen can modulate emotion and cognition function in post-menopause women, moreover SSRIs can influence estrogen system in rats and aquatic wildlife but most of them for reproductive ability. The aim of this study was to investigate the possible relationship between SSRI, estrogen, and emotion and cognition in post-menopause women with anxiety and depressive symptoms .Methods: A double-blind, randomized controlled trials of Paroxetine, an SSRI (n = 44), versus placebo (n = 38) for 6 months in post-menopausal women with anxiety and depressive symptoms. For screening anxiety, depression and mild cognitive impairment (MCI), we use the Hamilton Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D) and the Chinese Version of the Montreal cognitive assessment (MoCA-CV). And sex hormones were measured by ELASE method which is serum estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH). Results: Paroxetine increased serum E2 and decreased LH, FSH significantly (P < 0.05). Meanwhile, HAM-A and HAM-D scores declined and MoCA-CV score raised by Paroxetine (P < 0.05). We also found that a negative association between E2 and scores of HAM-A and HAM-D at pre-treatment and post-treatment of Paroxetine (HAM-A: R = ?0.27, R = ?0.24; HAM-D: R = ?0.65, R = ?0.37), while a positive correlation between E2 and MoCA-CV scores (R = 0.52, R = 0.47). Conclusions: This founding suggests that SSRI can increase serum estrogen levels and the change of estrogen may be one of mechanism in SSRI’s improve emotion and cognitive function in post-menopausal women.

Computer Science , 2014,
Abstract: Recreation of flight trajectory is important among research areas. The design of a flight trajectory recreation and playback system is presented in this paper. Rather than transferring the flight data to diagram, graph and table, flight data is visualized on the 3D global of ossimPlanet. ossimPlanet is an open-source 3D global geo-spatial viewer and the system realization is based on analysis it. Users are allowed to choose their interested flight of aerial mission. The aerial photographs and corresponding configuration files in which flight data is included would be read in. And the flight statuses would be stored. The flight trajectory is then recreated. Users can view the photographs and flight trajectory marks on the correct positions of 3D global. The scene along flight trajectory is also simulated at the plane's eye point. This paper provides a more intuitive way for recreation of flight trajectory. The cost is decreased remarkably and security is ensured by secondary development on open-source platform.

Research on the Reform of the Review Method of College Professional Titles Based on Point System  [PDF]
Weihuang Dai, Xiaofang Chen
Journal of Service Science and Management (JSSM) , 2018, DOI: 10.4236/jssm.2018.114031
Abstract: Taking the confidentiality principle of professional title as the entry point, based on the existing problems of college titles, such as simple feedback mechanism, being lack of pertinence, unfairness, etc., this paper proposes a new title review method based on the point system to change the traditional system review voting method. At the same time, the review index method is introduced, and the specific operation of the case is described in detail by Analytic Hierarchy Process (AHP) and Precedence Chart (PC). It is hoped that through the reform of the review method, the openness and fairness of professional title review process will be further improved, and the incentive effect of college titles should be brought into play to promote the long-term development of colleges and teachers.
Segmentation-based multi-scale urban green space landscape

SUN Xiaofang,LU Jian,SUN Yibin,

应用生态学报 , 2006,
Abstract: In this study, three scales urban green space landscapes were generated by multi-resolution segmentation. With 50 and 300 pixels as the object segmentation thresholds, the small- and large-scale landscape object image layers were produced, and the two object image layers were obtained by the nearest neighbor classification method. The result of small-scale landscape classification image was segmented into middle-scale landscape image, and then classified. Green space information was extracted through vector form of object image layers of three scales landscape classification. The landscape indexes diversity, dominance, evenness, fractal dimension, fragmentation, and interior to edge ration were calculated, with the largest values of the former four indexes being 2. 2, 0. 681, 0. 948, and 0. 326, and the smallest values being 1. 641, 0. 122, 0. 707, and 0. 113, respectively, indicating that the diversity, evenness and fragmentation decreased, while the dominance increased with increasing land- scape scale. The method of multi-resolution segmentation to generate multi-scale landscape could meet the needs of urban green space landscape research.

International Journal of Molecular Sciences , 2005, DOI: 10.3390/i6120303
Abstract: We herein describe a method of depositing hemoglobin (Hb) and sulfonated polyaniline (SPAN) on GC electrodes that facilitate interfacial protein electron transfer. Well-defined, reproducible, chemically reversible peaks of Hb and SPAN can be obtained in our experiments. We also observed enhanced peroxidase activity of Hb in SPAN films. These results clearly showed that SPAN worked as molecular wires and effectively exchanged electrons between Hb and electrodes.Mediated by Conjugated Polymers

环境工程学报 , 2013,
Abstract: The urban wastewater discharge can provide fundamental data for drainage engineering design, the Gray System Theory is widely used to forecast urban wastewater discharge. Based the urban wastewater discharge in Tianjin from 2001 to 2009, Gray Model was established to forecast the discharge of domestic sewage and industrial wastewater in Tianjin from 2010 to 2015. As the data of industrial wastewater was characterized as great fluctuation, Markov Model was introduced to amend the results of Gray Model. The results showed that the forecasting results of industrial wastewater by Gray Markov Model had high accuracy. The domestic sewage discharged would be 651.2057 million tons and the industrial wastewater discharged would be 193.3939 million tons in 2015. It indicated that the percentage of domestic sewage discharge in urban wastewater discharge having an increase trend as time goes on.
