Characterizing some regularities of ordered semigroups by their anti-hybrid ideals [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
We focus on mappings called hybrid structures. A hybrid structure can be regarded as a combination of a soft set and a fuzzy set. Therefore, with the help of the products of union softs sets and fuzzy sets, we can define a new product of hybrid ...

Monotone subsequence via ultrapower

open access: yesOpen Mathematics, 2018
An ultraproduct can be a helpful organizing principle in presenting solutions of problems at many levels, as argued by Terence Tao. We apply it here to the solution of a calculus problem: every infinite sequence has a monotone infinite subsequence, and ...

Light Management With Grating Structures in Optoelectronic Devices

open access: yesFrontiers in Chemistry, 2021
Ordered and patterned micro/nanostructure arrays have emerged as powerful platforms for optoelectronic devices due to their unique ordered-dependent optical properties.

The structure of first-order causality [PDF]

open access: yesMathematical Structures in Computer Science, 2009
Game semantics describe the interactive behaviour of proofs by interpreting formulas as games on which proofs induce strategies. Such a semantics is introduced here for capturing dependencies induced by quantifications in first-order propositional logic.

Estimating ordered categorical variables using panel data: a generalized ordered probit model with an autofit procedure [PDF]

open access: yes
Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption).

Entropy Generation through Deterministic Spiral Structures in Corner Flows with Sidewall Surface Mass Injection

open access: yesEntropy, 2016
Results are presented for an innovative computational procedure that predicts time-dependent instabilities and deterministic ordered structures in three-dimensional steady-state laminar boundary-layer flows.

Characterizing the Ordered AG-Groupoids Through the Properties of Their Different Classes of Ideals

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
In this article, we have presented some important charcterizations of the ordered non-associative semigroups in relation to their ideals. We have initially characterized the ordered AG-groupoid through the properties of the their ideals, then we ...

Hierarchical Hydrogels with Ordered Micro-Nano Structures for Cancer-on-a-Chip Construction

open access: yesResearch, 2021
In the drug therapy of tumor, efficient and stable drug screening platforms are required since the drug efficacy varies individually. Here, inspired by the microstructures of hepatic lobules, in which hepatocytes obtain nutrients from both capillary ...

Fuzzy neighborhood structures on partially ordered groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Ahsanullah (1988) showed the compatibility between group structures and I-fuzzy neighborhood systems. In this paper, we require not only that the I-fuzzy neighborhood systems be compatible with the group structures, but also compatible with the order ...
