Lightweight formal methods promise to yield modest analysis results in an extremely rapid manner. To fulfill this promise, they must be able to work with existing information sources, be able to analyze for manifestly desirable properties, be highly automated (especially if dealing with voluminous amounts of information), and be readily customizable ancl flexible in the face of emerging needs a...

Trajectory data play a fundamental role to an increasing number of applications, such as transportation management, urban planning and tourism. Trajectory data are normally available as sample points. However, for many applications, meaningful patterns cannot be extracted from sample points without considering the background geographic information. In this paper we propose a novel framework for...

among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (phbv) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. phbv has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. nanofibers are noticeably employed in order to enhance the performance of biomaterials,...

DE-DIFFERENTIATION OF PAROTID ACINAR CELLS IN VITRO Andrew S. Currie July 16, 2010 Background: When rat salivary gland cells are cultured in vitro, they dedifferentiate within 24 h. Hypothesis: Growth factors will prevent de-differentiation of primary cultures of parotid gland cells, and they will induce differentiation of ParC5 cells. DNA methylation drives de-differentiation and the loss of e...

The csxPOI system enables its users to collaboratively create, share, and modify points of interest, which describe geographic places with explicit semantic properties instead of using vague annotations such as tags. Users can edit their own points of interest and those shared by others, but also adapt the structure of the ontology underlying the semantic annotations. The interface for all user...

The article describes the derivational differentiation of proper nouns (onomastic units) from appellative lexicon, their specific features, conversion (lexical-semantic) method word formation and within scientific interpretation this method, onomastic its simple different aspects, toponyms in Uzbek language by conversion, toponymization (toponymization) appellatives are highlighted on basis evi...

This contribution investigates the content-based feature extraction methods used in visual information retrieval, focusing on concepts that are employed for the semantic representation of media content. The background part describes the building blocks of feature extraction functions. Since numerous methods have been proposed we concentrate on the metaconcepts. The building blocks lead to a dis...

Semantic segmentation in LiDAR point clouds has become an important research topic for autonomous driving systems. This paper proposes a dynamic graph convolution neural network cloud semantic using polar bird’s-eye view, referred to as DGPolarNet. are converted coordinates, which rasterized into regular grids. The points mapped onto each grid distribute evenly solve the problem of sparse distr...

Properties of the hybrid of block-pulse functions and Lagrange polynomials based on the Legendre-Gauss-type points are investigated and utilized to define the composite interpolation operator as an extension of the well-known Legendre interpolation operator. The uniqueness and interpolating properties are discussed and the corresponding differentiation matrix is also introduced. The appl...
