Fuzzy connectedness and fuzzy clustering are two well-known techniques for fuzzy image segmentation. The former considers the relation of pixels in the spatial space, but does not inherently utilize their feature information. On the other hand, the latter does not consider the spatial relations among pixels. In this paper, a new segmentation algorithm is proposed in which these methods are comb...

According to the norms and collective efficacy model, the levels of social connectedness within a local community are a function of neighborhood structural characteristics, such as socioeconomic status and ethnic composition. The current work aims to determine whether neighborhood structural and institutional features (neighborhood wealth, percentage of immigrants, population density, opportuni...

Background: The exponential growth of smartphones has afforded many users with ubiquitous access to socialization as seen in the various mobile apps used to communicate and connect with others. The present study employed mixed-method approaches to analyse the impact of phubbing on social connectedness among adolescents in Malaysia. Methods:</stron...

We study continua on which each nonconstant open mapping is light. W. Makuchowski asked if this property is preserved under atomic mappings. It is known that this is true under an additional assumption of arcwise connectedness of the domain continuum. We show that in general this is not true.

Population geneticists have shown that the effects of local extinction and recolonization on selectively neutral genetic diversity are sensitive to the number of individuals that migrate between groups. Here, we employ a spatially explicit metapopulation model to investigate the extent to which the effects of local extinction on selectively neutral cultural diversity and change are sensitive to...

About thirty years ago it was considered that Topology had two aspects, according to which its practitioners could be roughly divided into two schools. These aspects would today be termed global and local, and those whose interests lay mainly in global properties of a space or configuration formed one school, while those whose chief interest lay in local properties formed the other. The causes ...

1. The main purpose of this paper is to show that certain properties of a metrizable space, such as local connectedness or local contractibility or LCn or local compactness, hold uniformly with a properly chosen metric.2 This result, while easy to prove, seems to be new, and often permits simplifications in proofs dealing with various kinds of local connectedness. In §2, we obtain an analogous ...

Let I denote an ideal of a local Gorenstein ring (R, m). Then we show that the local cohomology module H I (R), c = height I, is indecomposable if and only if V (Id) is connected in codimension one. Here Id denotes the intersection of the highest dimensional primary components of I. This is a partial extension of a result shown by Hochster and Huneke in the case I the maximal ideal. Moreover th...
