Let G be a graph of order p, and let a, b and n be nonnegative integers with b ≥ a ≥ 2, and let f be an integer-valued function defined on V (G) such that a ≤ f(x) ≤ b for each x ∈ V (G). A fractional f -factor is a function h that assigns to each edge of a graph G a number in [0,1], so that for each vertex x we have dG(x) = f(x), where d h G(x) = ∑ e3x h(e) (the sum is taken over all edges inc...
تعریف: فضای توپولوژی x، یک فضای k تفکیک پذیر نامیده می شود، اگر به ازای هر دو نقطه متمایز a و b از آن، بتوانیم یک تابع c(x,k) f بیابیم که f(a)=1 و f(b)=0. تعریف: فضای توپولوژی x با خاصیت t1 را، k- منظم می نامیم هرگاه به ازای هر x a و هر زیر مجموعه بسته که بتوانیم یک تابع c(x,k) f بیابیم که f(a)=1 و f(x)=0 و b در x . ابتدا توجه می کنیم که فضاهای k- منظم غیر یکسان ریخت x و y موجودند که (x,k)c و...
Let S be a non empty set and let a, b be elements of S. The functor a, b, ... yields a function from N into S and is defined by the condition (Def. 1). (Def. 1) Let i be a natural number. Then (i) if there exists a natural number k such that i = 2 ·k, then (a, b, ...)(i) = a, and (ii) if it is not true that there exists a natural number k such that i = 2 ·k, then (a, b, ...)(i) = b. We now stat...

Although temozolomide has shown clinical activity against neuroblastoma, this activity is likely limited by the DNA repair enzyme O-methylguanine DNA methyltransferase (MGMT). We hypothesized that IFN-B could sensitize neuroblastoma cells to the cytotoxic effects of temozolomide through its ability to down-regulate MGMT expression. In vitro proliferation of three neuroblastoma cell lines treate...
