Generalization of f-Graphs and Their Algebraic Aspects

Journal of Mathematics, 2023
The notion of f-graphs and f-ideals are relatively new and have been studied in many papers. In this paper, we have generalized the idea of f-graphs and f-ideals to quasi f-graphs and quasi f-ideals, respectively. We have characterized all quasi f-graphs

An Algorithm for Computing the Limit Points of the Quasi-component of a Regular Chain [PDF]

, 2013
For a regular chain $R$, we propose an algorithm which computes the (non-trivial) limit points of the quasi-component of $R$, that is, the set $\bar{W(R)} \setminus W(R)$.

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, EarlyView.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2016
Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S,  ,  is called an (m, n)-ideal of S if (i) Am SAn  A, and (ii) if x  A, y  S such that y  x, then y  A. In this paper, necessary and sufficient conditions for every (

Quasi-prime ideals

, 2018
In this paper, the new concept of quasi-prime ideal is introduced which at the same time generalizes the `prime ideal' and `primary ideal' notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which generalizes the Zariski topology.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

Advanced Functional Materials, EarlyView.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Countable Ideals in a Semi-Lattice of the De Enumeration Degrees

Моделирование и анализ информационных систем, 2015
In the article we have proved that any countable ideal in the semi-lattice of the De is the intersection of two principal ideals generated by quasi-minimal covers for this ideal.

The revised JBI critical appraisal tool for the assessment of risk of bias for quasi-experimental studies

JBI Evidence Synthesis
Systematic reviews of effectiveness offer a rigorous synthesis of the best evidence available regarding the effects of interventions or treatments. Randomized controlled trials are considered the optimal study design for evaluating the effectiveness of ...
