A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs).Optically significant constituent includes chlorophyll a concentration (Chl a), a proxy of phytoplankton biomass, absorption of colored detrital matter

Comparing Machine Learning Models for Pupillary Light Reflex–Based Autism Spectrum Disorder Classification

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Autism spectrum disorder (ASD) prevalence is rising globally, underscoring the critical need for early detection to improve intervention outcomes. Atypical pupillary light reflex (PLR) has emerged as a promising biomarker for this purpose. This study leverages machine learning to enhance the accuracy of early ASD screening in children aged 3–6.

Bipolar Fuzzy Dot Structures on Subalgebras of a β‐Algebra

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this article, we present the concepts of bipolar fuzzy dot β‐subalgebras (BFD β‐SAs) within the context of β‐algebra and explore their associated characteristics. We establish the connections between a BF β‐SA and a BFD β‐SA. We examine the homomorphic and inverse images of BFD β‐SAs and prominent results.

Fuzzy Set Theoretic Approach to Generalized Ideals in BCK/BCI-Algebras

Journal of Function Spaces, 2022
This paper deals with the study of generalizations of fuzzy subalgebras and fuzzy ideals in BCK/BCI-algebras. In fact, the notions of ∈,∈∨κ~∗,qκ~-fuzzy subalgebras, ∈,∈∨κ~∗,qκ~-fuzzy ideals, and ∈∨κ~∗,qκ~,∈∨κ~∗,qκ~-fuzzy ideals in BCK/BCI-algebras are ...

On the Structural Behavior of Multiplicative (Generalized)‐Derivations via d‐Algebra Structures

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In the context of a d‐algebra structure (℧, ∗, 0), this paper aims to introduce the concept of a multiplicative (generalized)‐derivation G associated with a self‐map Ξ (not necessarily a derivation). Based on this concept, the operations ∧ and composition ° will be defined, and several interesting related properties will be investigated, such as ...

Fixed‐Point Hoop Algebras and Lattice‐Theoretic Properties of Derivation Classes

Journal of Mathematics, Volume 2026, Issue 1, 2026.
We introduce three classes of derivations on hoop algebras—pseudo implicative, implicative, and f‐implicative—and investigate their algebraic characteristics through detailed examples. We establish that, under natural conditions, the collection of pseudo implicative derivations forms a bounded distributive lattice.

The p-semisimple property for some generalizations of BCI algebras and its applications

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2020
This paper presents some generalizations of BCI algebras (the RM, tRM, *RM, RM**, *RM**, aRM**, *aRM**, BCH**, BZ, pre-BZ and pre-BCI algebras). We investigate the p-semisimple property for algebras mentioned above; give some examples and display various

Ideal Theory in BCK/BCI-Algebras Based on Soft Sets and 𝒩-Structures

Discrete Dynamics in Nature and Society, 2012
Based on soft sets and 𝒩-structures, the notion of (closed) 𝒩-ideal over a BCI-algebra is introduced, and related properties are investigated. Relations between 𝒩-BCI-algebras and 𝒩-ideals are established.

Parametric Inference for a Multicomponent Stress–Strength Reliability Model With Kumaraswamy Distribution Under Ordered Ranked Set Sampling

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Assessing reliability in systems with dual stress constraints needs a flexible model and effective sampling methods. A framework using the Kumaraswamy distribution is set up for multicomponent stress and strength systems. Data collection is done through ordered ranked set sampling, leveraging the unified theory of generalized order statistics to ...

On Q-algebras

International Journal of Mathematics and Mathematical Sciences, 2001
We introduce a new notion, called a Q-algebra, which is a generalization of the idea of BCH/BCI/BCK-algebras and we generalize some theorems discussed in BCI-algebras.
