在理论研究和专家访谈的基础上构建高职院校数学教师核心素养模型.通过维度设计、项目选编和评估编制"高职院校数学教师核心素养量表",进行整体层面和分层面的探索性因素分析,通过逐项删除不合理题项,从而确认量表的因素结构,建立量表的建构效度.进一步采用结构方程模型法对量表进行验证性因素分析,经由对初始模型的3次修正,最终得到一个二阶因素模型与实际数据相契合,因此说明量表具有建构效度.该模型的二阶因素为高职院校数学教师核心素养,3个一阶因素为知识、能力和品性,其中知识因素可以分为本体性知识和条件性知识两个观测变量,能力因素分为数学能力、数学教学能力和专业发展能力3个观测变量,品性因素则分为认识信念和态度两个观测变量.

考虑产品族按订单装配(ATO)制造商以通用零部件和专用零部件组装生产同一产品族中两种内在价值不同的产品,建立了基于顾客驱动型需求替代的产品族ATO制造商产品定价及零部件补货模型.通过理论及仿真分析,给出了ATO制造商最优定价及补货策略.研究表明:同一产品族中的不同产品间价差不宜大于其内在价值之差,且价格之比也应不超过内在价值之比;当内在价值低的产品缺货时,愿意购买内在价值高的产品作为替代的顾客比例为两种产品内在价值之比,内在价值高的产品缺货时,所有的顾客都愿意购买内在价值低的产品作为替代;ATO制造商在制定最优销售价格和销售时长时,只需考虑产品内在价值,零部件采购价格以及单位保管成本,无需考虑产品族的单位时间潜在总需求.

Journal of Electronic Science and Technology of China 2008年第4期6卷 462-465页

作者： Wen-Tao z.ang Fang Li yu-Liang Liu Optoelectronic SystemLaboratory Institute of Semiconductors Chinese Academy of SciencesBeijing 100083 China

A fiber Bragg grating （FBG） hydrophone with enhanced sensitivity is demonstrated. A novel piston-like diaphragm with a hard core fixed at the center is used as the sensing element. Theoretical analysis shows that the Young＇s modulus of the diaphragm and the radius of the hard core have significant effect on the pressure sensitivity. Experiments are carried out to test this effect and the performance of the hydrophone. The static measure- ment result is in good agreement with the theoretical result and an acoustic sensitivity of 7 nm/MPa has been achieved.

Objective:To study the effect of sunitinib on renal cancer cell growth and invasion in vitro as well as Wnt/β-catenin signaling ***: Renal cancer cell lines ACHN were cultured and processed with different doses of sunitinib (1 μmol/L, 2 μmol/L, 4 μmol/L and 8 μmol/L), and sunitinib-free processing condition was used as negative control. 24 h after processing, the mRNA expression levels of apoptosis genes, invasion genes and Wnt/β-catenin signaling pathways in cells were ***: 24 h after treatment, NPRL2, Bax, caspase-3 and caspase-9 mRNA expression in 1 μmol/L, 2 μmol/L, 4 μmol/L and 8 μmol/L sunitinib groups were significantly higher than those in negative control group while MMP2, MMP9, Vimentin, N-cadherin, Wnt andβ-catenin mRNA expression were significantly lower than those in negative control group;the higher the dose of sunitinib, the higher the NPRL2, Bax, caspase-3 and caspase-9 mRNA expression while the lower the MMP2, MMP9, Vimentin, N-cadherin, Wnt andβ-catenin mRNA expression in ***: Sunitinib can inhibit the Wnt/β-catenin signaling pathway in renal cancer cells to increase the expression of apoptosis genes, inhibit the expression of invasion genes and thereby inhibit the cell growth and invasion.

Agricultural Biotechnology 2016年第4期5卷 46-50页

作者： yu LI Liquan WU Rongfu WANG Juan LI School of Resources and Environment Anhui Agricultural University School of Agronomy Anhui Agricultural University Biotechnology Center Anhui Agricultural University

Stresses are defined as a variety of environmental factors that pose adverse impacts on plant growth and survival. Rice is an important food crop, whose quality and yield may be affected by environmental stresses. MicroRNAs play an important role in response to stresses, which regulate gene expression at the post-transcription level by cleaving target mRNAs and inhibiting mRNA translation. This paper summariz.d the mechanism of action of miRNAs and introduced research progress of miRNAs in rice under biotic and abiotic stresses, which provided reference for revealing the functional role of rice miRNAs in stress resistance.

Background Prior research about N400 has been mainly based on English stimuli,while the *** of Chinese characters is still *** aim of the present study was to further investigate the semantic processing of Chinese *** Event related potentials （ERP） component N400 was elicited by 38 pairs of matching （congruent） and mismatching （incongruent） ended Chinese idioms：ending words with same phoneme but different shape and meaning （sPdSdM）,with similar shape but different phoneme and meaning（sSdPdM）,with same meaning but different phoneme and shape（sMdPdS）,and words with different phoneme,shape and meaning（dPdSdM）and recorded by Guangz.ou Runjie WJ-1 ERP *** 62 right-handed healthy adults（age 19-50 years）,N400 amplitudes and latencies were compared between matching and mismatching conditions at Fz.Cz.and *** N400 showed a midline distribution and could be elicited in electrodes Fz. Cz.and *** mean values of N400 latencies and amplitudes were obtained for matching and mismatching ending werds in healthy *** differences were found in N400 latencies and amplitudes in matching and mismatching ending-werds idioms in healthy adults（P〈0.05）.Compared with matching ending-werds jdioms, N400 latencies were prolonged and the amplitudes were increased in mismatching ones.N400s elicited by different types of stimuli showed different latencies and *** longest N400 latency and largest N400 amplitude were elicited by ending-werds with *** gender difference was found of N400 latency and amplitude in this study （P〉0.05）.Conclusions Compared with English *** ideographic words could provide more flexible stimuli for N400 research in that the werds have 3-dimension *** and *** of N400 elicited by matching and mismatching ending words in Chinese idioms are mainly determined by the meaning of the *** issues of N400 elicited by Chinese characters deserve further
