Two-letter words and a fundamental homomorphism ruling geometric contextuality

, 2016
It has recently been recognized by the author that the quantum contextuality paradigm may be formulated in terms of the properties of some subgroups of the two-letter free group $G$ and their corresponding point-line incidence geometry $\mathcal{G}$.

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

Advanced Functional Materials, EarlyView.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.

Iridescent Perfect Absorption in Critically-Coupled Acoustic Metamaterials Using the Transfer Matrix Method

Applied Sciences, 2017
The absorption performance of a locally-reacting acoustic metamaterial under oblique incidence is studied. The metamaterial is composed of a slotted panel, each slit being loaded by an array of Helmholtz resonators.

Side‐Chains Engineered Self‐Assembly of Ortho‐Benzodipyrrole‐Based Acceptors: Comprehensive Exploration of Structure‐Interface‐Photovoltaics Correlations

Advanced Functional Materials, EarlyView.
The side‐chain configuration in the bay region of C‐shaped ortho‐benzodipyrrole‐based non‐fullerene acceptors plays a crucial role in their self‐assembly, single‐crystal structures, and optoelectronic properties. The closely correlated molecular structure and performance underscore the importance of minimizing A–A self‐aggregation and enhancing D–A ...

A PRESENTATION OF DESARGUES’ THEOREM APPLYING THE DESCRIPTIVE GEOMETRY RULES

Journal of Industrial Design and Engineering Graphics, 2006
This paper presents Desargues’ theorem in two ways: – the solution by incidence and succession; - the solution by the application of the descriptive geometry rules.

Symbolic incidence geometry and finite linear spaces

Discrete Mathematics, 1994
Symbolic incidence geometry (SIG) is a common project of some European Universities. The project has the task to develop a computer program package that will allow geometers to use the computer for their research in incidence geometry. In this paper the author presents a concept of how linear spaces can be dealt with in the SIG.

Combinatorial Designs with Two Singular Values II. Partial Geometric Designs [PDF]

In this and an earlier paper [17] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize (v, k, ë) designs, and include uniform multiplicative designs and partial geometric designs.Here we study the latter,
