Interframe Variation Vector: A Novel Feature for Gait Recognition

Gait representation is an important issue in gait recognition. A simple yet efficient approach, called Interframe Variation Vector (IVV), is proposed. IVV considers the spatio-temporal motion characteristic of gait, and uses the shape variation information between successive frames to represent gait signature.Different from other features, IVV rather than condenses a gait sequence into single image resulting in spatial sequence lost; it records the whole moving process in an IVV sequence. IVV can encode whole essential features of gait and preserve all the movements of limbs. Experimental results show that the proposed gait representation has a promising recognition performance.     

Description of a new species of Armandia (Polychaeta: Opheliidae) from western Kyushu,Japan, with character variations

Armandia amakusaensis sp. nov. (Polychaeta: Opheliidae) is described from an intertidal sandflat in western Kyushu, Japan. The holotype measures 13.14 mm in total body length, and has 32 setigers, with branchiae on setigers 2–31. Eleven pairs of lateral eyes are present on setigers 7–17. The anal funnel opens dorsally, fringed with 11 papillae, its length being slightly shorter than the length of the last three setigers. A long unpaired cirrus originates mid-ventrally from the inside of the anal funnel. Variation in these diagnostic characters is described. The new species is most similar to A. leptocirris (Grube, 1878) and A. intermedia Fauvel, 1902. However, it is distinguished from A. leptocirris in the distribution patterns of the branchiae and the lateral eyes, and from A. intermedia in the distribution pattern of the lateral eyes, the ratio of anal funnel length to total body length, and the number of anal-funnel papillae.     

Partitioning phenotypic variation: genotypic,environmental and residual components from bryozoan skeletal morphology

Using morphometric studies of colonial (clonal) organisms such as Bryozoa grown as replicates in controlled laboratory experiments, phenotypic variation (hard part morphology) can be partitioned into its genotypic and environmental (ecophenotypic) components. The interaction between these, i.e. different genotypic responses to the same environmental change, can also be recognized. Palaeobiological studies are inherently constrained by species concepts based on morphotypes (preserved morphological phenotype). Uncertainties associated with fossil species concepts restrict the deductive resolution potential of fossil taxa in discussions of the broader biological questions of species evolution, ecology, biogeography and phylogeny. The relationship between species-level morphological variation and genetic variation in modern taxa is central to evaluating the viability of fossil morphotypes as biological species. Results from a preliminary study of three genotypes of Electra pilosa L., grown as replicate colonies in tanks comprising different microenvironmental conditions, allow for direct evaluation of morphospecies concepts. Numerical analyses (Cluster Analysis, Principal Component Analysis and Two-way ANOVA) of six morphometric characters demonstrated a strong Genotype control over zooid morphology and limited environmental (Tank) effects with minimal environmental differences among tanks. No significant Genotype by Tank (=environment) interactions were found for any characters. These results demonstrate that it is possible to quantify the extent to which a given trait is plastically expressed in different environments. The strong degree of correlation between morphology and genetics for this species is encouraging for the use of morphotypes as proxies for biological species.     

对相对论“长度变化”的深度分析

本文以相对论长度收缩效应为基础,分析计算了＂特种杆＂从静止加速到匀速运动状态时的长度变化,得出了静止长度变长的结论。再以相对论效应的普适性为由,将此结论推广到普通物体。文章进一步解释了历史上的贝尔飞船悖论,分析论证了相对论长度变化对长度测量的影响,通过设计思想实验,对相对论提出了质疑。     

山水审美：启蒙与终极关怀的主题变奏

中国古人浓厚的自然本位思想和中国优良的山水环境使中国山水审美文化在古代得到了充分的发展,贯穿其发展过程的是终极关怀与审美启蒙两大主题的交融与变奏。     

变分迭代法求解量子力学中的微扰问题

微扰法求解量子力学中的微扰问题具有一定的局限性。本文把变分法和迭代法结合起来考虑量子力学中的微扰问题，解决了微扰方法不能解决的问题。更重要的是该方法不仅可以求出基态能量和基态波函数的近似值，也可以求出一、二级，甚至，n级能量的近似值和对应状态的近似波函数。     

论汉族四大民间传说在畲族地区发生变异的内外在原因

牛郎织女、孟姜女、白蛇传和梁山泊与祝英台这四部作品，享有“汉族四大民间传说”的美誉。这四大传说在畲族中广泛流传。在畲族地区，这几部作品与畲族的文化传统、民族性格、地方景物和风俗习惯等结合，在思想内容、人物形象和情节等方面都发生了较大的变异。讲唱者记忆力和表达能力的差异性、再创作的随意性以及畲族所处历史条件和区域的不同，是汉族四大民间传说在畲族地区发生变异的内外在原因。     

健康黑松幼苗中的电波传递

以健康黑松功苗为材料，用非伤害性刺激（如冷冻）和伤害性刺激（如烧伤、刺伤、化学伤害等）引发植物体内的波形的变化。研究表明，非伤害性刺激能在幼苗体内引起动作电波的传递，伤害性刺激除了能引起和电波的传递外，还能引起较复杂的变异电波的传递，并对这种现象进行了讨论。
