Changes in the structure of the nucleolus during the cell cycle of the Chinese hamster cell in vitro were studied. Quantitative electron microscopic techniques were used to establish the size and volume changes in nucleolar structures. In mitosis, nucleolar remnants, "persistent nucleoli," consisting predominantly of ribosome-like granular material, and a granular coating on the chromosomes wer...

This paper discusses foundations of conventional style of rule mining in which rules are extracted from a data table. Rule mining mainly uses the structure of a table, data partition, but two different approaches are observed: divide and conquer and covering: the former focuses on the nature of data partition and the latter does on the nature of information granules. This paper illustrates that...

The influence of CO2 on the corrosion characteristics 42CrMo steel through heat treatment was systematically investigated. results revealed that had a widmanstatten structure before treatment, and Fe3C in laminar. However, it exhibited granular bainite after granular. rate increased treatment. film occurred severe spallation, protective properties were reduced. lamellar inhibited local flow Fe2...

Oxygen vacancy-rich high-entropy (Cr 0.2 Mn Fe Co Ni ) 3 O 4 oxide nanofibres with granular structure are good candidates for the preparation of electrocatalytic inks.

We present a granular synthesis (GS) technique that produces environmental-like sounds using sampled sound grains and meso-time control functions. This approach is related to physical modeling (PM) (Smith, 1992; VŠlimŠki & Takala, 1996) and traditional granular synthesis (GS) (Roads, 1996, 299; Truax, 1988) but we have worked on two issues that have been previously neglected in these techniques...

We unravel how mechanical stress heterogeneity and core-periphery asymmetry in tissue spheroids are modulated by their granular micro-structure, means of simulations with a deformable cell model.

Granular computing deals with representation of information in the form of some aggregates and related methods for transformation and analysis for problem solving. A granulation scheme based on clustering and Rough Set Theory is presented with focus on structured conceptualization of information has been presented in this paper. Experiments for the proposed method on four labeled data exhibit g...

We report the existence of self-organization in wet granular media or slurries, mixtures of particles of different sizes dispersed in a lower density liquid. As in the case of dry granular mixtures, axial banding (alternating bands rich in small and large particles in a long rotating cylinder) and radial segregation (in quasi-2D containers) are observed in slurries. However, when compared with ...

We use the first Betti number of a complex to analyze the morphological structure of granular samples in mechanical equilibrium. We investigate two-dimensional granular packings after a tapping process by means of both simulations and experiments. States with equal packing fraction obtained with different tapping intensities are distinguished after the introduction of a filtration parameter whi...

We present an x-ray microtomography study of the three-dimensional structural correlations in monodisperse granular packings. By measuring an orientation-dependent pair correlation function, we find that the local structure shows an angularly anisotropic orientation correlation. The correlation is strongest along the major axis of the local Minkowski tensor of the Voronoi cell. It turns out tha...
