let $g$ be a simple graph. an independent set is a set ofpairwise non-adjacent vertices. the number of vertices in a maximum independent set of $g$ isdenoted by $alpha(g)$. in this paper, we characterize graphs $g$ with $n$ vertices and with maximumnumber of maximum independent sets provided that $alpha(g)leq 2$ or $alpha(g)geq n-3$.

Ftr1p is the permease component of the Fet3p-Ftr1p high affinity iron-uptake complex, in the plasma membrane of Saccharomyces cerevisiae, that transports the Fe3+ produced by the Fet3p ferroxidase into the cell. In this study we show that Ftr1p probably has seven transmembrane domains with an orientation of N-terminal outside, and C-terminal inside the cell. Within the context of this topology ...

The plasma membrane contains some enzymes whose active sites face the external medium rather than the cytoplasm, and these enzymes have been called ‘ectoenzymes’ [ 1,2]. The biological function of an ectoenzyme can thus be explored by treatment of intact cells with impermeant reagents which inactivate the enzyme. Determination of the time course of return of the catalytic activity to steady sta...

conclusions the present study provides the first experimental evidence in support of dexmedetomidine treatment for cocaine-induced seizures. premedication with dexmedetomidine reduces seizure activity in a mouse model of acute cocaine toxicity. in addition, while dexmedetomidine may be effective, moxonidine and alpha-methyldopa did not effectively prevent cocaine-induced lethality. results the ...

Suppose $$\{P_{n}^{(\alpha , \beta )}(x)\} _{n=0}^\infty $$ is a sequence of Jacobi polynomials with \alpha >-1.$$ We discuss special cases question raised by Alan Sokal at OPSFA in 2019, namely, whether the zeros P_{n}^{(\alpha ,\beta )}(x)$$ and P_{n+k}^{(\alpha + t, s are interlacing if $$s,t >0$$ k \in {\mathbb {N}}.$$ consider two this for consecutive degree prove that P_{n+1}^{(\alpha 1 )...
