Characterization of A5 and PSL(2,7) by sum of elements orders [PDF]

open access: yesInternational Journal of Group Theory, 2013
Let $G$ be a finite group. We denote $psi(G)=sum_{gin G}o(g)$ where $o(g)$ denotes the order of $g in G$. Here we show that $psi(A_5)< psi(G)$ for every nonsimple group $G$ of order 60. Also we prove that $psi(PSL(2,7))groups $G$ of order 168.

Finite simple groups and finite primitive permutation groups [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1983
The classification of the finite simple groups has had far-reaching consequences for many branches of algebra. This paper is a discussion of several problems about primitive permutation groups which have been solved using the simple group classification.

On a New Criterion for the Solvability of Non-Simple Finite Groups and m-Abelian Solvability

open access: yesJournal of Mathematics, 2021
This paper is devoted to introduce a sufficient condition for the solvability of finite groups. Also, it presents the concepts of m-abelian and m-cyclic solvability as new generalizations of solvability and polycyclicity, respectively.

Thin finite simple groups [PDF]

open access: yesJournal of Algebra, 1976
A group G is of characterstic 2 type if F*(M) = O,(M) for each 2-local subgroup M of G. It seems likely that in the near future the problem of determining the finite simple groups will be reduced to the determination of the characteristic 2 type groups.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Quasirecognition by prime graph of finite simple groups ${}^2D_n(3)$ [PDF]

open access: yesInternational Journal of Group Theory, 2014
Let $G$ be a finite group. In [Ghasemabadi et al., characterizations of the simple group ${}^2D_n(3)$ by prime graph and spectrum, Monatsh Math., 2011] it is proved that if $n$ is odd, then ${}^2D _n(3)$ is recognizable by prime graph and also by ...

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Large subgroups of simple groups

open access: yes, 2014
Let $G$ be a finite group. A proper subgroup $H$ of $G$ is said to be large if the order of $H$ satisfies the bound $|H|^3 \ge |G|$. In this note we determine all the large maximal subgroups of finite simple groups, and we establish an analogous result ...

Sustainable bioplastics manufacturing from renewable sources

open access: yesFEBS Open Bio, EarlyView.
Bioplastics are manufactured by using polymers from different bio‐based sources. These novel materials not only offer biodegradability but also possess various functional properties that make them suitable for diverse applications. Recent developments in the preparation of bioplastics are reported, highlighting the distinct properties of each type of ...
