A 2500-year sea level change record in Fildes Peninsula, Antarctica

A detailed record of sea level changes during the last 2500 years is preserved in the northernwest coast of Fildes Peninsula in Antarctica. Fourteen marine alga layers were deposited in the beach with an altitude of 2.80 m, and one diatom layer deposited in the ancient lake on the terrace with an altitude of 6.84 m. A radiocarbon age of 695±70 aBP was obtained for the modern marine alga, and the age was used in correction for the carbon reservoir effect of the marine alga. Sea level fell 4.98 m from the 4th century B.C. to the early 13th century, at an average of -0.31 cm/a, then rose about 0.78 m during the early 13th to the middle 18th century, at an average of 0.14 cm/a. It has risen about 0.16 m since the middle 18th century, at an average of 0.07 cm/a.     

一种面向测试的RTL行为抽象与蕴含方法

针对寄存器传输级（register transfer level,RTL)行为的抽象，提出了一种层次化的带条件的表示，这种抽象的行为是面向测试的，它不仅表达简单，而且能很方便地进行蕴含操作，通过抽象，电路可以规范为行为集，并代替电路本身进行功能测试向量的生成，在测试生成过程中，大量地应用蕴含操作何以使其中的行为得到简化，并极大地提高了系统的效率。     

Frequent mtDNA mutations and its role in gastric carcinogenesis

In order to disclose the relationship between mutations of mitochondrial DNA (mtDNA) and gastric carcinogenesis, we screened the entire mtDNA sequence in 30 cases of human gastric cancer and matched normal tissues by using denaturing high-performance liquid chromatography (DHPLC) and DNA sequencing. Our data showed that high frequency (66.7%, 20/30) of mitochondrial genome mutation occurred in gastric cancer. Among these variants, 17 cases (56.7%, 17/30) were identified to be somatic mutation. High level mutant frequency was found in ND4, ND5 coding genes and D-loop control region, which was 36.7%, 26.7% and 30% respectively. Comparing with complexes Ⅲ, Ⅳ and Ⅴof the electron transport chain, we found that variants appeared to be more frequent in the subunit genes of complexⅠ. Most of mutations were base substitutions (85.4%, 41/48). Our results suggested that mutations of subunit genes encoding complexⅠ, especially ND3, ND4 and ND5 genes, might contribute to human gastric carcinogenesis.

刑事法治视野中的"亲亲相隐"

"亲亲相隐"是我国古代法制的一项基本原则,它在当代中国的存在仍然有其合理性和必要性.故应对其予以重新分析和审视,实现其在当代法治建设中的创造性转换.     

技术视野下的人与自然关系

为构建人与自然的和谐相处,现代技术的“双刃剑”效应需要人们理性的思考和认真的对待。本文从马克思主义哲学的角度阐述了技术不同于科学的内涵、负面效应及人的责任;从分析技术悲观主义、技术乐观主义与技术现实主义的基础上审视技术价值观的选择,实施可持续发展的生态文明模式;并要求在意识、科教、法律与道德和国际合作等方面采取措施,促进人与自然关系的和谐发展。     

城市可持续发展水平的指标体系及评价

从经济、环境、资源、社会发展和人口5个方面构建了评价城市可持续发展水平的指标体系.由于涉及到众多的指标,选择因子分析法通过降维处理,能使较多原始指标被综合为几个较少指标.实例证明,指标的选取、方法的选择都比较合理.

人文视野里的语文和语文教育

人文是人对自身本质特性的思索和探寻,包括理想人性及其实现方式,这种实现方式在人类社会主要体现为文化行为.人文视野里的语文表现出学科文化内蕴的综合性,言语符号内容与形式的同步性,人文精神展示的完整性等突出特点.要在语文教学中凸现人文性,必须注重教学行为的人文方式,教学材料的人文底蕴,文本解读的人文基点.
