Common Neighborhood Energy of the Non-Commuting Graphs and Commuting Graphs Associated with Dihedral and Generalized Quaternion Groups

Mathematics
This paper explores the common neighborhood energy (ECN(Γ)) of graphs derived from the dihedral group D2n and generalized quaternion group Q4n, specifically the non-commuting graph (NCM-graph) and the commuting graph (CM-graph).

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

Advanced Materials, EarlyView.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

Higher-dimensional automorphic lie algebras [PDF]

, 2016
The paper presents the complete classification of Automorphic Lie Algebras based on sln(C)sln(C) , where the symmetry group G is finite and acts on sln(C)sln(C) by inner automorphisms, sln(C)sln(C) has no trivial summands, and where the poles are in ...

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

Advanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...

Shunkov Groups with Additional Finiteness Conditions, Containing Dihedral Subgroups

Известия Иркутского государственного университета: Серия "Математика"
In this paper, Shunkov groups are studied in the context of the well-known question of B. Amberg and L. S. Kazarin about the structure of groups containing direct products of a finite number of dihedral groups.

Codes in a Dihedral Group Algebra

Automatic Control and Computer Sciences, 2019
In 1978, Robert McEliece constructed the first asymmetric code-based cryptosystem using noise-immune Goppa codes; no effective key attacks has been described for it yet. By now, quite a lot of code-based cryptosystems are known; however, their cryptographic security is inferior to that of the classical McEliece cryptosystem.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

On product-one sequences over dihedral groups

, 2021
Let G be a finite group. A sequence over G means a finite sequence of terms from G, where repetition is allowed and the order is disregarded. A product-one sequence is a sequence whose elements can be ordered such that their product equals the identity ...

Algebras and Dihedral Defect Groups

Proceedings of the London Mathematical Society, 1987
Let F be an algebraically closed field of characteristic 2, and let G be a finite group. Let B be a block of the group algebra FG with dihedral defect group D of order \(2^ n\). It has been proved by \textit{R. Brauer} [Symp. Math. 13, 367-393 (1974; Zbl 0288.20010)] that B has either 1, 2 or 3 simple modules.
