There are six classes of endomorphisms for a graph. The sets these form chain under the inclusion sets. In order to systematically study endomorphisms, Böttcher and Knauer defined concepts endomorphism spectrum type graph in 1992. this paper, based on property structure monoids graphs, double-edge fan graphs described. particular, we give spectra types graphs.

In this paper, numerical and experimental investigations on an axial-flow fan with grooved/double-sectional blades are performed to improve its performance in terms of volume flow rate and noise at a local operating point. The target fan is used to cool a mechanical room of a household refrigerator. However, it is found that the target system has more resistance than that for which the fan is o...

1. Neither the duration nor severity of symptoms of upper respiratory tract infection was reduced after Traditional Chinese medicine treatment with either Jing Fan Bai Du san or Ying Qiao san. 2. For patients with wind-cold syndrome, Jing Fan Bai Du san might be able to improve general health more than placebo. 3. Both Jing Fan Bai Du san and Ying Qiao san were well tolerated, with no excess in...

Diberikan graf terhubung dan sederhana $G=(V(G), E(G))$ bilangan bulat positif $k$. Himpunan $S \subseteq V(G)$ disebut sebagai pembangkit $k$-metrik jika untuk setiap pasang titik berbeda $u,v \in V(G)$, terdapat paling sedikit $k$ $w_{1}, w_{2}, \ldots, w_{k} S$ sedemikian sehingga $d(u,w_{i}) \neq d(v,w_{i})$ $i \{1,2,\ldots, k\}$, dengan $d(u,v)$ adalah panjang \emph{path} terpendek dari $u...

It is important to keep in mind that SIGCOMM runs a double-blind reviewing process. By double-blind we mean that authors don’t know who their reviewers are, and reviewers don’t know who the authors are. Personally, I’m a big fan of double-blind reviewing. Double-blind reviewing focuses attention on the papers, rather than who wrote the papers. And every year there are some surprises — SIGCOMM a...

Aptamers can be chemically modified to enhance nuclease resistance and increase target affinity. In this study, we performed chemical modification of 2'-deoxyinosine in AS1411, an anti-proliferative G-rich oligodeoxynucleotide aptamer, which binds selectively to the nucleolin protein. Its function was augmented when 2'-deoxyinosine was incorporated at positions 12, 13, 15, and 24 of AS1411, res...
