The evolution of many morphological structures is associated with the behavioral context of their use, particularly for structures involved in copulation. Yet, few studies have considered evolutionary relationships among the integrated suite of structures associated with male reproduction. In this study, we examined nine species of lizards in the genusAnolisto determine whether larger copulatory morphologies and higher potential for copulatory muscle performance evolved in association with higher copulation rates. In 10–12 adult males of each species, we measured the size of the hemipenes and related muscles, the seminiferous tubules in the testes, and the renal sex segments in the k.dneys, and we assessed the fiber type composition of the muscles associated with copulation. In a series of phylogenetically-informed analyses, we used field behavioral data to determine whether observed rates of copulation were associated with these *** found that species with larger hemipenes had larger fibers in the RPM (the retractor penis magnus, a muscle that controls hemipenis movement), and that the evolution of larger hemipenes and RPM fibers is associated with the evolution of higher rates of copulatory behavior. However, the sizes of the seminiferous tubules and renal sex segments, and the muscle fiber composition of the RPM, were not associated with copulation rates. Further, body size was not associated with the size of any of the reproductive structures investigated. The results of this study suggest that peripheral morphologies involved in the transfer of ejaculate may be more evolutionarily labile than internal structures involved in ejaculate production.

An Improved EZW Hyperspectral Image Compression

引用

Journal of Computer and Communications 2014年第2期2卷 31-36页

作者： k.i-Jen Cheng Jeffrey C. dill School of Electrical Engineering and Computer Science Ohio University Athens USA.

The paper describes an efficient lossy and lossless three dimensional (3D) image compression of hyperspectral images. The method adopts the 3D spatial-spectral hybrid transform and the proposed transform-based coder. The hybrid transforms are that k.rhunen-Loève Transform (k.T) which decorrelates spectral data of a hyperspectral image, and the integer Discrete Wavelet Transform (DWT) which is applied to the spatial data and produces decorrelated wavelet coefficients. Our simpler transform-based coder is inspired by Shapiro’s EZW algorithm, but encodes residual values and only implements dominant pass incorporating six symbols. The proposed method will be examined on AVIRIS images and evaluated using compression ratio for both lossless and lossy compression, and signal to noise ratio (SNR) for lossy compression. Experimental results show that the proposed image compression not only is more efficient but also has better compression ratio.

化学过程和生命现象大都在溶剂中进行,对它们进行分子模拟研究的时候,模拟体系里往往有大量的溶剂分子（一般为水分子）。所以,对这些水分子开发合适的、准确快速的模型,对分子模拟、药物设计等诸多研究领域的发展都有重要意义。我们基于SEA（Semi-Explicit Assembly）这一研究思路,认为溶质的溶剂化自由能是溶质分子表面上溶剂化能量场的加和函数。我们通过一系列电荷、LJσ、ε参数各不相同的LJ球体在显式溶剂TIP3P中的模拟数据,提取出分子表面和分子性质,以及分子表面溶剂化能量场和分子表面性质的函数关系。根据这两个函数关系,可以得到任意分子的溶剂化自由能（极性部分和非极性部分分开计算）。我们用这个溶剂模型计算了原子数从1到约50,电荷从-2到+2的大量不同种类溶质分子的溶剂化能量,取得了满意的结果:计算精度和TIP3P模型相当,速度却和GB（Generalized Born）模型相当。该溶剂模型进一步用于更加复杂的分子（SAMPL4）以及更加复杂的电解质溶液体系,也都取得了满意的结果。
