A novel mechanism for jumping in the indian ant<Emphasis Type="Italic">Harpegnathos saltator</Emphasis> (Jerdon) (Formicidae,Ponerinae)

The Indian antHarpegnathos saltator may be unique among insects in using its jumping capacity not only as an escape mechanism but also as a normal means of locomotion, and for catching its prey in flight. High-speed cinematography used to analyse the various phases of the jump suggests thatHarpegnathos employs a novel jumping mechanism to mediate these behaviours: namely the synchronous activation of its middle and hindlegs. Electrophysiological recordings from muscles or nerves in pairs of middle and hindlegs show remarkably synchronous activity during fictive jumping, supporting the synchronous activation hypothesis.Harpegnathos is not the only ant to jump, and a cladistic analysis suggests that jumping behaviour evolved independently three times during ant evolutionary history.

Pattern formation in Rayleigh-Bénard convection: Numerical simulation with a coupled-map-lattice model

The various patterns formed in Rayleigh-Bénard convection under different conditions are numerically simulated with a coupled-map-lattice model. In the case of a lower aspect ratio (L/d=5), the simulations vividly depicted the main features of the transition process from a laminar state to a soft turbulence and then to a hard turbulence. In this case, the cellular structure in a horizontal section is also reproduced. In the case of a larger aspect ratio (L/d=30), the simulations successfully reproduced the spiral-defect chaos and target chaos in the initial stage of the pattern evolution which were recently found in experiments. In this case, for a fluid ofPr=1, it is verified in simulations that both the ideal straight rolls and spiral-defect chaos are stable attractors in the same parameter regime, and that the initial condition is a decisive factor for which one of the two is formed. In the same case, for a fluid ofPr=4, the target patterns are dominant instead of the spirals, the sizes and distributions of the target are also notably dependent on the initial condition.     

基于B样条修匀公式的边缘检测的改进方法

边缘检测是图像分割中的一个重要部分．本文依据B样条修匀公式的图像边缘检测的基本思想，但又因为用B样条函数光滑后的图像对原始图像的逼近性并不十分精确，即它们的误差图像中残留着一些可能造成检测到的边缘线不连续或有用特征可能检测不到的边缘信息，为减少残量误差，本文对图像原型值采取盈亏修正，然后再对修正的图像使用B样条修匀公式做全息光滑曲面，重新得到的曲面改进了逼近性，同时还具有足够的光滑性和良好的保凸性．

帽儿山森林生态系统蚯蚓区系组成研究

帽儿山林区蚯蚓种类较丰富，有2科6属8种，正蚓科的赤子爱胜蚓、粉正蚓及微小双胸蚓为优势种，从年龄结构上看，该地区蚯蚓种群属增长型，成蚓少于幼蚓，对林型系列研究表明白桦林的蚯蚓数量最少，对生态系列蚯蚓研究表明，蚯蚓生物量和个体密度随着地形坡位的升高而增大，热量因子对森林生态系统蚯蚓种群分布起着重要作用。
