Empirical Analysis on Rural Financial Development and Farmers' Income Increase in China

The growth of farmer＇s incomes is cIoseIy reIated to rural finance. The research analyzed the dynamic reIationship of rural financial deveIopment, efficiency and farmer＇s incomes based on VAR modeI, and the resuIts indicated that the ex-pansion of rural finance wouId stimuIate farmer＇s incomes in a Iong term, and the growth of rural financial efficiency significantIy improves farmer＇s incomes in a short term, instead of a Iong term. Hence, it is necessary to introduce more credit funds and social funds to rural areas, deepen rural financial system reform and acceIerate use rate of Ioan capital and enhance guidance for farmers and township enterprises in use of Ioan capitals.

Assessment of Land Comprehensive Carrying Capacity in Lin'an City

According to regional characteristics and the actual situation in Lin ’an City, an evaluation index system of land comprehensive carrying capacity composed of three support subsystems （eco-environment, social and economic carrying capaci-ties） containing 22 evaluation indexes was established to evaluate the comprehen-sive carrying capacity of land resource in Lin’an City during 2005-2012. Meanwhile, based on the target data of overal land use plan, the level of land comprehensive carrying capacity was predicted at the end of the plan period （2020） .The results showed that land comprehensive carrying capacity had a significant growth in Lin ’an from 2005 to 2012, and the development trend was basical y sustainable. The sub-systems also had been greatly improved, in which the constant improvement of ec-ological environment carrying capacity made the largest contribution to the constant raising of land comprehensive carrying capacity. The degree of coordination between the systems was poor, in which eco-environment carrying capacity had the maxi-mum growth, far more than the social and economic carrying capacities. According to the land comprehensive carrying capacity in 2020, utilization of land resources in Lin＆#39;an city can achieve sustainable development in general. Final y, proposals of im-proving comprehensive carrying capacity were put forward in terms of the enhance-ment of eco-environment protection, accelerating economic development and policy guidance.

A novel image encryption scheme based on Keplers third law and random Hadamard transform

In this paper, a novel image encryption scheme based on Keplers third law and random Hadamard transform is proposed to ensure the security of a digital image. First, a set of Kepler periodic sequences is generated to permutate image data, which is characteristic of the plain-image and the Keplers third law. Then, a random Hadamard matrix is constructed by combining the standard Hadamard matrix with the hyper-Chen chaotic system, which is used to further scramble the image coefficients when the image is transformed through random Hadamard transform. In the end, the permuted image presents interweaving diffusion based on two special matrices, which are constructed by Kepler periodic sequence and chaos system. The experimental results and performance analysis show that the proposed encrypted scheme is highly sensitive to the plain-image and external keys, and has a high security and speed, which are very suitable for secure real-time communication of image data.

Improvement of the thermoelectric efficiency of pyrene-based molecular junction with doping engineering

In this study, the thermoelectric properties of pyrene molecule doped with boron and nitrogen atom at different sites of molecule are investigated using density functional theory and none-equilibrium Greens function formalism in the linear response regime. Our calculations show that when the impurities are added to the edge of the molecule, the anti-resonant peaks will appear in the transmission diagram in the vicinity of the Fermi energy level. So it increases the thermoelectric figure of merit of the system in comparison with the one that the impurity is located in the center of molecule. Additionally, the seebeck coefficient signs are not the same among the B, N, and N ＆ B doped devices, indicating that the types of the carriers can be changed with different types of doping.

2个Ⅰ型Waardenburg综合征家系的基因诊断及产前诊断

目的 分析2个中国汉族Ⅰ型Waardenburg综合征（WS1）家系致病基因PAX3的突变位点,并在此基础上探讨PAX3基因分析用于产前诊断的可行性.方法 2015年7月和2016年3月分别有2例汉族家族遗传性WS1患者在郑州大学第一附属医院就诊,采集2个家系（WS1-01和WS1-02）成员血样并留取临床资料.应用多聚酶链反应（PCR）结合sanger测序和多重连接探针扩增技术（multiplex ligation-dependent probe amplification,MLPA）对2个WS1家系中2例先证PAX3基因进行检测,获得变异序列后,针对所检出变异序列对家系成员和健康对照个体的PAX3基因序列进行变异验证分析;确定致病性突变后,对WS1-01家系中的高危胎儿进行孕中期产前诊断.结果 在WS1-01家系的患者中均检测出了PAX3基因第7外显子杂合缺失,家系中表型正常者和20名健康对照者均未检测到此突变;高危胎儿未检测出与患者相同的致病突变,出生后表型正常.在WS1-02家系的2例患者中均检测到AX3基因第8外显子c.1385_1386delCT微小缺失突变（可导致移码框的改变）,家系中表型正常者和200名健康对照者均未检测到此突变.结论 PAX3基因第7外显子缺失突变和第8外显子c.1385_1386delCT是本研究2个WS1家系的致病原因,测序分析结合MLPA技术可对该2个WS1家系进行有效的基因诊断和产前诊断.
