In the present paper, Radial Basis Function interpolations are applied to approximate a fuzzy function $tilde{f}:Rrightarrow mathcal{F}(R)$, on a discrete point set $X={x_1,x_2,ldots,x_n}$, by a fuzzy-valued function $tilde{S}$. RBFs are based on linear combinations of terms which include a single univariate function. Applying RBF to approximate a fuzzy function, a linear system wil...

the main goal of this paper is to introduce and study a new class of function via the notions of $e$-$theta$-open sets and $e$-$theta$-closure operator which are defined by özkoç and aslım cite{10} called weakly $er$-open functions and $e$-$theta$-open functions. moreover, we investigate not only some of their basic properties but also their relationships with other types of already existing to...

a {em roman dominating function} on a graph $g$ is a function$f:v(g)rightarrow {0,1,2}$ satisfying the condition that everyvertex $u$ for which $f(u) = 0$ is adjacent to at least one vertex$v$ for which $f(v) =2$. {color{blue}a {em restrained roman dominating}function} $f$ is a {color{blue} roman dominating function if the vertices with label 0 inducea subgraph with no isolated vertex.} the wei...

background: eurycoma longifolia jack (elj) has been shown to elevate serum testosterone and increased muscle strength in humans. this study investigated the effects of physta® a standardized water extract of elj (400 mg/day for 6 weeks) on testosterone: epitestosterone (t:e) ratio, liver and renal functions in male recreational athletes. methods: a total of 13 healthy male recreational athletes...

A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.

The theory of circle packings and, more generally, of circle patterns enjoys in recent years a fast development and a growing interest of specialists in complex analysis and discrete mathematics. This interest was initiated by Thurston’s rediscovery of the Koebe-Andreev theorem [K] about circle packing realizations of cell complexes of a prescribed combinatorics and by his idea about approximat...

the aim of this study was to compare the effectiveness of fenugreek (trigonella foenum-graecum) with that of lovastatin in restoration of endothelia function in the aorta taken form aged n-mair rats. for this purpose, 4 groups of old n-mari rats were used (n=6), normal saline treated control group, lovastatin (10 mg/kg, orally) and fengreek seed powder in normal saline suspension (100 or 500 mg...

cognitive impairment may be a common even at the onset of multiple sclerosis (ms). in this case-control study, we tried to find out the probable relationship between homocysteine levels and cerebral atrophy or cognitive impairment in patients with multiple sclerosis. one hundred fifty six patients who had ms according to mcdonald diagnostic criteria were included in this study. patients’ age, g...
