Temporal Distribution of Fish Community Structure in Dongting Lake Estuary  [PDF]
Xiping Yuan, Xin Yang, Hongzi Ge, Hong Li, Daqing Deng
Agricultural Sciences (AS) , 2019, DOI: 10.4236/as.2019.103025
Abstract: The Dongting Lake Estuary is migration pathways for some river-lake migratory and semi-migratory fishes. In the present study, an annual survey of fish was conducted from January to November 2018 covering a total of 6 sites in Dongting Lake Estuary. A total of 57 freshwater species and subspecies belonging to 5 orders and 10 families were recorded. The catches at the Dongting Lake Estuary were mainly composed of Lake settled fish. The biomass of Cyprinus (Cyprinus) carpio Linnaeus was the highest, accounting for 25.53% of the total catches, followed by Hypophthalmichthys molitrixs, Culter alburnus Basilewsky and Ctenopharyngodon idellus, accounting for 10.41%, 8.99% and 7.10% of the total catches, respectively. The four major domestic carps accounted for 26.13% of the total catch. The range of richness of species varied between 40 and 51 species. The trend was fewer species in spring, with the arrival of summer and autumn gradually increasing, peaking at the turn of summer and autumn, and then gradually decreasing with the arrival of winter, to the lowest in spring. The Shannon, Simpson, Pielou and Margalef indices showed the consistent trends with richness of species.
Genetic Structure of Spinibarbus caldwelli Based on mtDNA D-Loop  [PDF]
Xiping Yuan, Xin Yang, Hongzi Ge, Hong Li
Agricultural Sciences (AS) , 2019, DOI: 10.4236/as.2019.102015
Abstract: Spinibarbus caldwelli was an endemic species to China, and its germplasm protection and resources utilization had become more and more concerned. To know its genetic diversity and differentiation, the mitochondrial DNA D-loop was amplified and sequenced for 148 individuals from four regions of Pearl River and Yangtze River Basin. Altogether 9 variable nucleotide sites existed among the aligned sequences of 748 bp, and 8 haplotypes were found within 148 individuals. The average nucleotide diversity (Pi) was high 0.00297, while haplotype diversity (Hd) was 0.706. The average genetic distance was 0.00298, most value occurred between LJ and CL populations, and small value occurred between HJ and QZ populations.
Stickiness of KAM tori for higher dimensional beam equation
Xiucui Song,Hongzi Cong
Mathematics , 2015,
Abstract: This paper is concerned with the stickiness of invariant tori obtained by KAM technics (so-called KAM tori) for higher dimensional beam equation. We prove that the KAM tori are sticky, i.e. the solutions starting in the $\delta$-neighborhood of KAM torus still stay close to the KAM torus for a polynomial long time such as $|t|\leq \delta^{-\mathcal{M}}$ with any $\mathcal{M}\geq 0$, by constructing a partial normal form of higher order, which satisfies $p$-tame property, around the KAM torus.
Evaluation of Magnetic Resonance Imaging Findings and Short-Term Outcome in Brain Metastatic Tumors after CyberKnife Treatment  [PDF]
Jiashou Hu, Hongzi Tian, Na Guo, Di Wang, Jinfeng Sun
International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2016, DOI: 10.4236/ijmpcero.2016.51010
Abstract: Objective: To evaluate the treatments’ outcomes in brain metastatic tumors after CyberKnife treatment according to magnetic resonance imaging (MRI) findings and improvement of symptoms. Methods: A retrospective analysis of CyberKnife treatment; 63 cases of patients with brain metastases; the use of CyberKnife treatment; short-term outcome evaluation after treatment and the MRI findings and measured before treatment and underwent diffusion-weighted imaging MRI scan of apparent diffusion coefficient (ADC) values. Results: 3 months after CyberKnife treatment and effectiveness were 82.5% and 96.8% respectively; 6 months and one year survival rates were 82.5% and 55.6% respectively; the median survival time was 16 months. MRI of 52 patients (67 lesions) ADC values after treatment increased to some extent than before treatment. There are 38 lesions volume to shrink or disappear, no enhancement or slight enhancement in the lesion, no edema zone; 27 lesions does not change in volume, no edema (18 lesions significantly weakened the degree of enhancement; 6 lesions showed no obvious change enhancement; 3 lesions showed ring enhancement, internal cystic); 2 lesions volume were larger, heterogeneous enhancement, peripheral edema. Conclusion: CyberKnife is an effective method for treating brain metastatic tumor. MRI can accurately evaluate tumor lesions after treatment.

Mathematics , 2014,
Abstract: It is proved that the KAM tori (thus quasi-periodic solutions) are long time stable for infinite dimensional Hamiltonian systems generated by nonlinear wave equation, by constructing a partial normal form of higher order around the KAM torus and showing $p$-tame property persists under KAM iterative procedure and normal form iterative procedure.
The Effects of Cigarette Smoke Extract on Ovulation, Oocyte Morphology and Ovarian Gene Expression in Mice
Zixin Mai, Ming Lei, Bolan Yu, Hongzi Du, Jianqiao Liu
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0095945
Abstract: Cigarette smoking can harm fertility, but the existing research has targeted primarily on ovarian follicles, embryos or sex hormone. In this study, we tested cigarette smoke extract on ovulation, oocyte morphology and ovarian gene expression associated with inhibition of oxidative stress using C57BL/6 mice. Mice in the experimental group were administered a cigarette smoke extract (CSE) solution (2 mg/ml) orally daily, while the blank control group was given dimethylsulfoxide (DMSO). A positive control group (menadione) was used that received an intraperitoneal injection of 15 mg/kg menadione in oil solution daily. We found that the CSE group manifested a reduced diameter of zona pellucida-free oocyte (ZP-free OD) and a morphologically misshapen first polar body (PB). Our results suggest that CSE exposure is associated with a shrink size and poor quality of oocytes. Quitting smoking is a wise choice to ensure good fertility.
Existence and Nonexistence of Global Solutions of a Fully Nonlinear Parabolic Equation  [PDF]

Advances in Pure Mathematics (APM) , 2013, DOI: 10.4236/apm.2013.31004
Abstract: In the paper, we study the global existence of weak solution of the fully nonlinear parabolic problem (1.1)-(1.3) with nonlinear boundary conditions for the situation without strong absorption terms. Also, we consider the blow up of global solution of the problem (1.1)-(1.3) by using the convexity method.
Research on Serving the Development of Regional Economy Innovation by Intellectual Properties in Universities  [PDF]
Ge Li
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.23005

At present, a sound intellectual property management and service system have not been established yet in Chinese colleges and universities. Meanwhile, the lost of existing intellectual property in universities due to small amount, low conversion rate, low technology content and weak brand awareness, hinders the positive effect of intellectual property and affects its transformation and application in China. This article introduces the current problems with intellectual property in universities and gives some countermeasures to promote the use of intellectual property in universities for a better regional economic service.

The Property of a Special Type of Exponential Spline Function  [PDF]
Ge Yang
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.513074
Abstract: Approximation theory experienced a long term history. Since 50’ last century, the rise of spline function as well as the advance of calculation promotes the growth of classical approximation theory and makes them develop a profound theory in maths, and application values have shown among the field of scientific calculation and engineering technology and etc. At present, the study of spline function had made a great progress and had a lot of fruits, as for that, the reader could look up the book [1] or [2]. Nevertheless, the research staff pays less attention to exponential spline function, since polynomial spline function is a special case of that, so it is much essential and meaningful for one to explore the nature of exponential spline function.
