The article is devoted to archaeological research of new discovered burial structures in the form of catacomb at the Kylyshzhar cemetery (1st century BC – 3rd century AD), in which artifacts were found similar to the monuments of the Sarmatian appearance. They include a number of ritual actions and burial implements close to the burial practice of the Sarmatians: range and blade weapons (iron tang daggers with a stone pommel, arrowheads), horse tack (iron girth buckles), bronze mirrors, household items and ritual objects (iron buckles, chalk amulets), jewelry (Egyptian faience ribbed beads). The characteristics of the grave goods from the catacombs of the Kylyshzhar cemetery, chronological calculations and ethno cultural interpretations indicate partial similarity between mentioned burials and the Sarmatian monuments of the 1st century BC – 3rd century AD despite major differences in such significant details of the funeral rite as the construction of burial pits and the orientation of the buried ones.

ABSTRACT The ywtD gene, which codes for an enzyme that degrades γ-polyglutamic acid (PGA), was cloned from Bacillus subtilis IFO16449. The gene is located immediately downstream of ywsC and ywtABC, a PGA operon involved in PGA biosynthesis, and it showed partial similarity to genes coding for dl-endopeptidase, a peptidoglycan-degrading enzyme. The ywtD gene, from which signal sequence is excised, was inserted into pET15b, and the recombinant plasmid was then transformed into Escherichia coli. Histidine-tagged YwtD was purified from sonicated cells of the transformant. The purified YwtD degraded PGA to yield two hydrolyzed products, a high-molecular-mass product (490 kDa with nearly 100% l-glutamic acid) and an 11-kDa product (with d-glutamic acid and l-glutamic acid in an 80:20 ratio). This finding and results of enzymatic analysis of the two products with carboxypeptidase G suggest that YwtD is a novel enzyme cleaving the γ-glutamyl bond only between d- and l-glutamic acids of PGA, and it may be designated γ-dl-glutamyl hydrolase.

A paper presents analysis of dynamic similarity between full-scale wind turbines tower-nacelle system and its laboratory model. As a reference real-world structure, Vensys 82 wind turbine was assumed. Complete and partial similarity criteria were both introduced. Considering laboratory model to be equipped with tuned mass damper horizontally arranged at the top, partial similarity of one pair of points (tower tips) motions will be satisfactory. On the basis of similarity conditions, laboratory model parameters were determined so that data acquired for the model may be referred to real-world structure.

This paper proposes a fast method for measuring the partial Similarity between 3D Model and 3D point Cloud (SimMC). It is crucial to measure SimMC for many point cloud-related applications such as 3D object retrieval and inverse procedural modelling. In our proposed method, the surface area of model and the Distance from Model to point Cloud (DistMC) are exploited as measurements to calculate SimMC. Here, DistMC is defined as the weighted distance of the distances between points sampled from model and point cloud. Similarly, Distance from point Cloud to Model (DistCM) is defined as the average distance of the distances between points in point cloud and model. In order to reduce huge computational burdens brought by calculation of DistCM in some traditional methods, we define SimMC as the ratio of weighted surface area of model to DistMC. Compared to those traditional SimMC measuring methods that are only able to measure global similarity, our method is capable of measuring partial similarity by employing distance-weighted strategy. Moreover, our method is able to be faster than other partial similarity assessment methods. We demonstrate the superiority of our method both on synthetic data and laser scanning data.

Visual data mining is a procedure aimed at a selection from a document’s repository subsets of documents presenting certain classes of objects; the last may be characterized as classes of objects’ similarity or, more generally, as classes of objects satisfying certain relationships. In this chapter attention will be focused on selection of visual documents representing objects belonging to similarity classes.
