Self-Dual and LCD Codes from Kneser Graphs K(n, 2) and Generalized Quadrangles

open access: yesMathematics
In this paper, we study self-dual and LCD codes constructed from Kneser graphs K(n, 2) and collinearity graphs of generalized quadrangles using the so-called pure and bordered construction. We determine conditions under which these codes are self-dual or

A spectrum result on maximal partial ovoids of the generalized quadrangle Q(4,q), q even [PDF]

open access: yes, 2010
This article presents a spectrum result on maximal partial ovoids of the generalized quadrangle Q(4,q), q even. We prove that for every integer k in an interval of, roughly, size [q2/10,9q2/10], there exists a maximal partial ovoid of size k on Q(4,q), q

Engineering Local Polar Frustration in Lead‐Free Dielectric Ceramics for Ultrahigh Normalized Energy Storage Performance

open access: yesAdvanced Functional Materials, EarlyView.
Local polar frustration is engineered to stabilize an ergodic relaxer through nanoscale multiphase coexistence, suppressing long‐range ferroelectric order while preserving high polarization. This strategy delivers ultrahigh low‐field normalized energy density (Wa >0.020 mC cm−2), exceptional thermal stability, and a transferable design principle for ...

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Generalized Quadrangles with a Spread of Symmetry

open access: yesEuropean Journal of Combinatorics, 1999
An incidence system of points and blocks is called a Steiner system \(S(t,k,v)\) if there exactly \(v\) points, every block is incident with exactly \(k\) points and every \(t\) different points are incident with exactly one block. A partial spread of a Steiner system is a set of mutually disjoint blocks.

Foundations of elation generalized quadrangles

open access: yesEuropean Journal of Combinatorics, 2006
The authors give a negative answer to the long-standing question whether or not the set of all elations about some point \(x\) forms a group for any thick generalized quadrangle \(S^{(x)}\) having \(x\) as an elation point or a center of transitivity. Furthermore, an answer is given for each of the known generalized quadrangles.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
