Coevolutionary analysis of resistance-evading peptidomimetic inhibitors of HIV-1 protease

We have developed a coevolutionary method for the computational design of HIV-1 protease inhibitors selected for their ability to retain efficacy in the face of protease mutation. For HIV-1 protease, typical drug design techniques are shown to be ineffective for the design of resistance-evading inhibitors: An inhibitor that is a direct analogue of one of the natural substrates will be susceptible to resistance mutation, as will inhibitors designed to fill the active site of the wild-type or a mutant enzyme. Two design principles are demonstrated: (i) For enzymes with broad substrate specificity, such as HIV-1 protease, resistance-evading inhibitors are best designed against the immutable properties of the active site-the properties that must be conserved in any mutant protease to retain the ability to bind and cleave all of the native substrates. (ii) Robust resistance-evading inhibitors can be designed by optimizing activity simultaneously against a large set of mutant enzymes, incorporating as much of the mutational space as possible.     

Noise analysis and synthesis for 3D laser depth scanners

This paper analyses the noise present in range data measured by a Konica Minolta Vivid 910 scanner, in order to better characterise real scanner noise. Methods for denoising 3D mesh data have often assumed the noise to be Gaussian, and independently distributed at each mesh point. We show via measurements of an accurately machined almost planar test surface that real scanner data does not have such properties: the errors are not quite Gaussian, and more importantly, exhibit significant short range correlation. We use this to give a simple model for generating noise with similar characteristics. We also consider how noise varies with such factors as laser intensity, orientation of the surface, and distance from the scanner. Finally, we evaluate the performance of three typical mesh denoising algorithms using real and synthetic test data, and suggest that new denoising algorithms are required for effective removal of real noise.

Edge-Aware Level Set Diffusion and Bilateral Filtering Reconstruction for Image Magnification

In this paper we propose an image magnification reconstruction method.In recent years many interpolation algorithms have been proposed for image magnification,but all of them have defects to some degree,such as jaggies and blurring.To solve these problems,we propose applying post-processing which consists of edge-aware level set diffusion and bilateral filtering.After the initial interpolation,the contours of the image are identified.Next,edge-aware level set diffusion is applied to these significant con...

离心泵叶轮轴面图的3点水力优化

叶轮轴面图设计的好坏直接影响离心泵效率,以双圆弧轴面图上的前盖板圆弧半径、前盖板倾角、后盖板圆弧半径、后盖板倾角几何参数为自变量,以3个工况点的加权平均水力效率最大为目标,采用Isight集成Pro/E、Gambit和Fluent对离心泵叶轮轴面图进行自动数值优化.采用超传递近似法来确定3个目标函数的权重因子.采用最优拉丁方试验设计方法确定优化样本.并采用该方法对一比转数为84.8的离心泵在0.8、1.0和1.2倍设计流量下的水力性能进行了优化.结果表明:优化后的3个工况点的加权平均水力效率提高了1.42百分点.因此,建立的离心泵叶轮轴面图的3点水力优化方法是可行有效的.
