On Groups in Which Many Automorphisms Are Cyclic

open access: yesMathematics, 2022
Let G be a group. An automorphism α of G is said to be a cyclic automorphism if the subgroup ⟨x,xα⟩ is cyclic for every element x of G. In [F. de Giovanni, M.L. Newell, A. Russo: On a class of normal endomorphisms of groups, J.

Testing the Clar theory: Cyclic conjugation in some benzo- and naphthaleno-annelated ovalenes [PDF]

open access: yesKragujevac Journal of Science, 2014
Cyclic conjugation (assessed by its energy effect) is studied in benzo- and naphthaleno-annelated ovalenes, in which annelation is in positions d and o.

Enhancing fluorescence and lowering the optical gap through CP doping of a π-conjugated molecular backbone: A computational-based design approach

open access: yesJournal of Photochemistry and Photobiology, 2021
Design principles of organic fluorescent materials are investigated at the molecular level using a first-principles-based computational approach. The design approach incorporates hetero atoms into a conjugated cyclic skeleton by introducing CP bonds. In

Splittings and automorphisms of relatively hyperbolic groups [PDF]

open access: yes, 2014
We study automorphisms of a relatively hyperbolic group G. When G is one-ended, we describe Out(G) using a preferred JSJ tree over subgroups that are virtually cyclic or parabolic. In particular, when G is toral relatively hyperbolic, Out(G) is virtually

Cyclic conjugation in benzo-annelated triphenylenes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Cyclic conjugation in benzo-annelated triphenylenes was studied by means of the energy effect (ef) and the π-electron content (EC) of the six-membered rings.

Ultrasound-sensitive cRGD-modified liposomes as a novel drug delivery system

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2022
Targeted liposomes enable the delivery of encapsulated chemotherapeutics to tumours by targeting specific receptors overexpressed on the surfaces of cancer cells; this helps in reducing the systemic side effects associated with the cytotoxic agents. Upon

Modulating Protein–Protein Interactions by Cyclic and Macrocyclic Peptides. Prominent Strategies and Examples

open access: yesMolecules, 2021
Cyclic and macrocyclic peptides constitute advanced molecules for modulating protein–protein interactions (PPIs). Although still peptide derivatives, they are metabolically more stable than linear counterparts, and should have a lower degree of ...

Infinity-Norm Permutation Covering Codes from Cyclic Groups

open access: yes, 2017
We study covering codes of permutations with the $\ell_\infty$-metric. We provide a general code construction, which uses smaller building-block codes.

Hierarchical wave function, Fock cyclic condition and spin-statistics relation in the spin-singlet fractional quantum Hall effect

open access: yes, 1993
We construct the hierarchical wave function of the spin-singlet fractional quantum Hall effect, which turns out to satisfy Fock cyclic condition. The spin-statistics relation of the quasi-particles in the spin-singlet fractional quantum Hall effect is ...

The embedding of a cyclic permutable subgroup in a finite group. II [PDF]

open access: yes, 2004
In two previous papers we established the structure of the normal closure of a cyclic permutable subgroup $A$ of a finite group, first when $A$ has odd order and second when $A$ has even order, but with an extra hypothesis that was unnecessary in the odd
