background postural instability is one of the common problems of aging. however, with increased age many systems of body such as musculoskeletal system are affected and changed. one of these changes is knee flexion contracture. the study aimed to investigate the simulated knee flexion contracture effects on postural stability in elderly. material and methods 15 elderly subjects (11 men, 4 women...

In this paper, characterizations of the degree to which a mapping $mathcal{T} : L^{X}longrightarrow M$ is an $(L, M)$-fuzzy topology are studied in detail.What is more, the degree to which an $L$-subset is an $L$-open set with respect to $mathcal{T}$ is introduced.Based on that, the degrees to which a mapping $f: Xlongrightarrow Y$ is continuous,open, closed or a quotient mapping with respect t...

Recently two new degree concepts have been defined in graph theory: ev-degree and ve-degree. Also the evdegree and ve-degree Zagreb and Randić indices have been defined very recently as parallel of the classical definitions of Zagreb and Randić indices. It was shown that ev-degree and ve-degree topological indices can be used as possible tools in QSPR researches . In this paper we d...

We analyze the asymptotic behavior of the degree sequence of Random Apollonian Networks [11]. For previous weaker results see [10, 11].

Definitions Abbreviation: A shortened form of a word, term or phrase used chiefly in writing to represent the full form (for example: 0 C for degree centigrade, N for nitrogen, ha for hectare, etc.) Acronym: More commonly used in writing and conversation, an acronym is formed by taking the initial letters of a name, term, or title (such as WO for Washington Office, NFS for National Forest Syste...
