Kinematic and dynamic characteristics' analysis of a scissor multi-rod ring deployable mechanism [PDF]

Mechanical Sciences, 2023
In this paper, the authors developed a double-layer ring truss deployable antenna mechanism (RTDAM) based on a scissor unit, which can be used as the deployment and support mechanism in large-aperture satellite antenna. Firstly, three configuration state

Extending the Ring Theory of Personhood to the Care of Dying Patients in Intensive Care Units [PDF]

Asian Bioethics Review, 2021
AbstractIt is evident, in the face of the COVID-19 pandemic that has physicians confronting death and dying at unprecedented levels along with growing data suggesting that physicians who care for dying patients face complex emotional, psychological and behavioural effects, that there is a need for their better understanding and the implementation of ...

Construction of Complex Lattice Codes via Cyclotomic Fields

Trends in Computational and Applied Mathematics, 2022
Through algebraic number theory and Construction $A$ we extend an algebraic procedure which generates complex lattice codes from the polynomial ring \mathbb{F}_{2}[x]/(x^{n}-1), where \mathbb{F}_{2}=\{0,1\}, by using ideals from the generalized ...

Vertex and region colorings of planar idempotent divisor graphs of commutative rings.

Iraqi Journal for Computer Science and Mathematics, 2022
The idempotent divisor graph of a commutative ring R is a graph with vertices set in R* = R-{0}, and any distinct vertices x and y are adjacent if and only if x.y = e, for some non-unit idempotent element e2 = e ? R, and is denoted by ?(R).

Gap-Size-Dependent Effective Phase Transition in Metasurfaces of Closed-Ring Resonators

Crystals, 2021
We theoretically investigate a metal-to-insulator transition in artificial two-dimensional (2D) crystals (i.e., metasurfaces) of tightly coupled closed-ring resonators.

Quasi-Regular Graphs Associated with Commutative Rings

Journal of Mathematics, 2022
One of the most important branches of mathematics is algebraic graph theory, which solves graph problems with algebraic methods. In graph theory, several algebraic properties of a ring can be represented.

Isosterism in pyrrole via azaboroles substitution, a theoretical investigation for electronic structural, stability and aromaticity

Heliyon, 2023
This work uses ab-initio CBS-QB3 and density functional theory (B3LYP) to analyze the structure, stability, and aromaticity of all isosteric nitrogen-boron pyrroles.
