following the idea of $l$-fuzzy neighborhood system as introduced byfu-gui shi, and its generalization to $(l,m)$-fuzzy neighborhood system, the relationship between  $(l,m)$-fuzzy topology and $(l,m)$-fuzzy neighborhood system will be further studied. as an application of the obtained results, we will describe the initial structures of $(l,m)$-fuzzy neighborhood subspaces and $(l,m)$-fuzzy top...

In this paper, new definitions of $L$-fuzzy closure operator, $L$-fuzzy interior operator, $L$-fuzzy remote neighborhood system, $L$-fuzzy neighborhood system and $L$-fuzzy quasi-coincident neighborhood system are proposed. It is proved that the category of $L$-fuzzy closure spaces, the category of $L$-fuzzy interior spaces, the category of $L$-fuzzy remote neighborhood spaces, the category of ...

AIM This study aimed to estimate the prevalence, incidence rate, and lifetime risk of developing atrial fibrillation (AF) in a population-based study of Swedish men. METHODS AND RESULTS The study is a part of 'The Study of Men Born in 1913', which is a longitudinal prospective cohort study of 855 men born in 1913 and living in the city of Gothenburg in Sweden. They were followed from the age ...

The different purposes present within a distributed information environment create the potential for repositories to enhance their metadata by capitalising on the diversity of metadata available for any given object. This paper presents three conceptual reference models required to achieve this optimisation of metadata workflow: the ecology of repositories, the object lifecycle model, and the m...

regarding iranian old cities, neighborhood has been a real place to live, a space for social interaction as well as economic activities. the concept of neighborhood has always been accompanied with senses of well-being, security and identity. in parallel with urban developments and changing lifestyles, neighborhoods have also faced the significant changes. in tehran as the capital, the changes ...

background: the purpose of this study is to determine association between personal, family, neighborhood, and social network characteristics and perceived intimacy in the neighborhood by the women. methods: in this cross‑sectional study, we applied a two‑stage sampling method to choose a representative sample of 150 married women and housewives, aged 15 to 49 years, who had education between si...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...

Main methods, algorithms and applications of the Variable Neighborhood Search metaheuristic are surveyed, in view of a chapter of the Encyclopedia of Optimization.

It is generally considered as self evident that the lifetime of our vacuum in the landscape of string theory cannot be much shorter than the current age of the universe. Here I show why this lower limit is invalid. A certain type of " parallel universes " is a necessary consequence of the string-landscape dynamics and might well allow us to " survive " vacuum decay. As a consequence our stringy...

In this paper the performance of the proposed DLMT and CLMT algorithms are compared. These proposed algorithms tend to extend the node lifetime. Decentralized lifetime maximizing tree(DLMT) features in nodes with higher energy to be chosen as data aggregating parents while Centralized Lifetime Maximizing Tree(CLMT) features with the identification of the bottleneck node to collect data in a cen...
