This article addresses the question of what information and new insights atomic force microscopy (AFM) provides that are of importance and relevance to cellular biophysical chemistry research. Three enabling aspects of AFM are discussed: (a) visualization of membrane structural features with nanometer resolution, such as microvilli, ridges, porosomes, lamellapodia, and filopodia; (b) revealing ...

Recently, there is a growing interest in seismic qualification of ridges, buildings and mechanical equipment worldwide due to increase of accidents caused by earthquake. Severe earthquake can bring serious problems in the wind turbines and eventually lead to an interruption to their electric power supply. To overcome and prevent these undesirable problems, structural design optimization of a sm...

We present a new method for first person sketch-based editing of terrain models. As in usual artistic pictures, the input sketch depicts complex silhouettes with cusps and T-junctions, which typically correspond to non-planar curves in 3D. After analysing depth constraints in the sketch based on perceptual cues, our method best matches the sketched silhouettes with silhouettes or ridges of the ...

Editing and deformation of irregular meshes have become standard tools in geometric modeling. Most approaches try to preserve low-level differential properties of the surface during editing, whereas the global structure and shape of the features are not explicitly taken into account. In this paper, we introduce a feature-driven editing approach that puts global structural properties of the shap...

Understanding the mechanisms at tool/chip interface during metal cutting is crucial in production of almost every metallic component used engineering applications. It critical to have rapid, durable, and reliable machining processes. This work contributes understanding occurring on tool secondary shear zone, it focusing side contact. Crystallographic textured Chemical Vapor Deposited (CVD) α-Al...

Lombazole, an antimicrobial agent of the imidazole class, induced profound ultrastructural changes in Staphylococcus epidermidis and Candida albicans, as observed by freeze fracture electron microscopy. In S. epidermidis cells, the primary effect on ultrastructure was characterized by a distinct change in the morphology of the plasma membrane. Secondary effects of lombazole were cell wall thick...

In this paper, we proposed a new fingerprint matching algorithm based on local geometric feature of fingerprint minutia and texture feature for each minutia. To describe the geometric feature of fingerprint minutia, we build a bi-minutia based bar model and get the geometric relationship between the bar and ridges of two candidate minutia; to demonstrate the texture feature, we creatively adopt...

in this article, rubber bumpers of double - wishbone suspension system have been modeled and analyzed. the objective of the present work is to predict the performance of these products during deformation, represent an optimum method to design, obtain stiffness characteristic curves and utilize the results in the automotive suspension dynamic analysis. these parts are nonlinear and exhibit large...

The network formed by ridges in a straightened sheet of crumpled paper is studied using a laser profilometer. Square sheets of paper were crumpled into balls, unfolded, and their height profile measured. From these profiles the imposed ridges were extracted as networks. Nodes were defined as intersections between ridges, and links as the various ridges connecting the nodes. Many network and spa...

In mathematical models for crystal microstructure [1,2,27], the deformation gradient is nearly piecewise constant in space to enable the deformation to attain a low energy. The length scale of the microstructure is limited by a surface energy associated with the transition from one piecewise constant variant phase to another piecewise constant variant phase [1, 27]. Motivated by these models, n...
