Ground state configuration of hydrogenated Biphenylene sheet: structure, stabilities, electronic and mechanical properties from first-principles calculations [PDF]

open access: yesarXiv, 2021
Based on first-principles calculations, the ground state configuration (Cmma-CH) of hydrogenated Biphenylene sheet (Science, 372, 852, 2021) is carefully identified from hundreds of possible candidates generated by RG2 code (Phys. Rev. B., 97, 014104, 2018).

Tricyclic antidepressant poisoning [PDF]

open access: yesCleveland Clinic Journal of Medicine, 2000
Tricyclic antidepressant poisoning causes predictable electrocardiographic abnormalities and can be lethal. Cardiac arrhythmias, hypotension, seizures, and coma are common. Sodium bicarbonate is still considered the treatment of choice for severe toxicity, although a variety of supportive measures may be taken.

The complement of enhanced power graph of a finite group [PDF]

open access: yesarXiv, 2022
The enhanced power graph $\mathcal{P}_E(G)$ of a finite group $G$ is the simple undirected graph whose vertex set is $G$ and two distinct vertices $x, y$ are adjacent if $x, y \in \langle z \rangle$ for some $z \in G$. In this article, we give an affirmative answer of the question posed by Cameron [6] which states that: Is it true that the complement ...

Tricyclic graphs with exactly two main eigenvalues [PDF]

open access: yesarXiv, 2003
An eigenvalue of a graph $G$ is called a main eigenvalue if it has an eigenvector the sum of whose entries is not equal to zero. In this paper, all connected tricyclic graphs with exactly two main eigenvalues are determined.

On reformulated zagreb indices with respect to tricyclic graphs [PDF]

open access: yesarXiv, 2014
The authors Mili$\breve{c}$evi$\acute{c}$ et al. introduced the reformulated Zagreb indices, which is a generalization of classical Zagreb indices of chemical graph theory. In the paper, we characterize the extremal properties of the first reformulated Zagreb index.
