I t pays to have a backup project in case your main research stalls. That's what Alan Hall (now at University College London) and colleagues learned when they set aside their studies on the protein ras and switched to its cousin rho. Their work (starting with Paterson et al., 1990) revealed that rho and related proteins were key regulators of the cell's actin cytoskeleton, and it set the stage ...

In this article, Imam Khomeini’s political theory is investigated with the Lakatos methodology. His methodology confirms the distinction between a hard core or the original skeleton of investments and experimental propositions confirms as a protective belt for the research program. Regarding this, the claim from this article is that if we understand the system of religious knowledge of Imam Kho...

A method of identification of curvature features for shape description and recognition is suggested. The method is based on the relation between local boundary features and the skeleton structure of a plain domain. It uses a continuous boundary-skeleton model of an image. The model consists of a boundary of a polygonal figure approximating a raster image, and a skeleton of the figure. To reveal...

For β ≥ 1, the β-skeleton depth (SkDβ) of a query point q ∈ Rd with respect to a distribution function F on Rd is defined as the probability that q is contained within the β-skeleton influence region of a random pair of points from F . The β-skeleton depth of q ∈ Rd can also be defined with respect to a given data set S ⊆ Rd. In this case, computing the β-skeleton depth is based on counting all...

In this paper, we propose an improved 3D star skeleton technique, which is a suitable skeletonization for human posture representation and reflects the 3D information of human posture. Moreover, the proposed technique is simple and then can be performed in real-time. The existing skeleton construction techniques, such as distance transformation, Voronoi diagram, and thinning, focus on the preci...

Table S1. Structure of compounds with different skeletons in the data set.

Skeleton lines of terrain, i.e. ridge and valley lines are essential features on topographic maps. A skeleton line is the one with minimum slope among the slope lines. Slope lines are the lines of the steepest slope. Skeleton lines are used for a wide range of aims, e.g. emphasizing land forms, generation of high fidelity digital terrain models, terrain generalization, determining characteristi...

This paper presents the results of a study on the use of morphological set operations to represent and encode a discrete binary image by parts of its skeleton, a thinned version of the image containing complete information about its shape and size. Using morphological erosions and openings, a finite image can be uniquely decomposed into a finite number of skeleton subsets and then the image can...

A method is proposed in this paper to automatically generate the animation skeleton of a model such that the model can be manipulated according to the skeleton. With our method, users can construct the skeleton in a short time, and bring a static model both dynamic and alive. The primary steps of our method are finding skeleton joints, connecting the joints to form an animation skeleton, and bi...
