فرض کنیم r حلقه جابجایی و z(r) مجموعه مقسوم علیه های صفر و reg(r) مجموعه اعضای منظم باشد. گراف تام از حلقه r را با ?(?(r)) نشان می دهیم. برخی خاصیتهای ?(?(r))، زمانیکه r حلقه جابجایی متناهی است را بررسی می کنیم و در این حالت یک کران بالا برای راس همبندی مشاهده می کنیم. همچنین ثابت می کنیم یال همبندی از ?(?(r)) برابر با مینیمم درجه آن است اگر و تنها اگر r حلقه جابجایی باشد بطوریکه z(r) ایده ...
The exposure of dark-grown Pharbitis nil seedlings to continuous R induces a rapid decrease in PHYA mRNA abundance with a half-life of about 2 h. A 5 min R pulse also induces this decline, and the effect is partially reversible by subsequent FR irradiation, confirming that the regulation of expression is mediated via the Pfr form of a phytochrome. When de-etiolated seedlings are returned to dar...
The effects of local anesthetics were examined on a family of transiently expressed neuronal calcium channels. Fomocaine, a local anesthetic containing a morpholine ring, preferentially blocked (Y,~ channels (Ki = 100 PM), and had a lower affinity (3to 15fold) for (Y,~, (Y,~, and cz,c channels. Block was incompletely reversible, followed I:1 kinetics, and did not affect steady-state inactivatio...
We propose the use of evolutionary algorithms (EAs) (Holland, 1992) to deal with the attribute selection task of referring expression generation. Evolutionary algorithms operate over a population of individuals (possible solutions for a problem) that evolve according to selection rules and genetic operators. The fitness function is a metric that evaluates each of the possible solutions, ensurin...
We completely determine those natural numbers $n$ for which the full matrix ring $M_n(F_2)$ and triangular $T_n(F_2)$ over two elements field $F_2$ are either n-torsion clean or almost clean, respectively. These results somewhat address settle a question, recently posed by Danchev-Matczuk in Contemp. Math. (2019) as well they supply more precise aspect nil-cleanness property of $n\times n$ all ...
To optimize nanoimprint lithography (NIL), it is essential to be able to characterize and control the NIL process in situ and in real time. Recently we have developed a real-time imprint monitoring by the scattering-of-light (RIMS) approach, which allows us to detect the degree of resist deformation and the duration of resist penetration by a mould during the imprint process in real time. In th...
Let $R$ be a reversible ring which is $alpha$-compatible for an endomorphism $alpha$ of $R$ and $f(X)=a_0+a_1X+cdots+a_nX^n$ be a nonzero skew polynomial in $R[X;alpha]$. It is proved that if there exists a nonzero skew polynomial $g(X)=b_0+b_1X+cdots+b_mX^m$ in $R[X;alpha]$ such that $g(X)f(X)=c$ is a constant in $R$, then $b_0a_0=c$ and there exist nonzero elements $a$ and $r$ in $R$ such tha...
The vascular endothelial growth factor (VEGF) system is of major importance for glomerular endothelial repair in glomerulonephritis (GN) and is significantly affected by nitric oxide (NO) release. For investigating whether glomerular upregulation of inducible NO synthase (iNOS) in GN might affect VEGF-mediated repair, a selective iNOS inhibitor, L-N6-(1-iminoethyl)-lysin (L-NIL), was administer...
runtime form of constructive negation does not have this advantage, but applies to many more programs. The simple form of the runtime method 1], given a negative goal :A, executes A; if A has a nite SLD-tree with answer substitutions (as substitution formulas) s 1 collection of substitutions in cases as described by Theorem 5, but in general cannot be presented this way. For example, the goal :...
In the present paper we extend the methods of the Weierstrass (or spinor) representation of surfaces in R [10, 11] and SU(2) = S [12] for surfaces in the threedimensional Lie groups Nil , S̃L2, and Sol endowed with so-called Thurston’s geometries [9]. The main feature of this approach is that the geometry of a surface is related to the spectral properties of the corresponding Dirac operator. The...
