Abstract This paper investigates the maximal subgroups of a free projection‐generated regular ∗$*$‐semigroup PG(P)${{\textsf {PG}}}(P)$ over a projection algebra P$P$, and their relationship to the maximal subgroups of the free idempotent‐generated semigroup IG(E)${{\textsf {IG}}}(E)$ over the corresponding biordered set E=E(P)$E = {{\textsf {E}}}(P)$.

Metric Based Attribute Reduction Method in Dynamic Decision Tables
Feature selection is a vital problem which needs to be effectively solved in knowledge discovery in databases and pattern recognition due to two basic reasons: minimizing costs and accurately classifying data.

Neighborhood Attribute Reduction: A Multicriterion Strategy Based on Sample Selection
In the rough-set field, the objective of attribute reduction is to regulate the variations of measures by reducing redundant data attributes. However, most of the previous concepts of attribute reductions were designed by one and only one measure, which ...

Definability of complex functions in o‐minimal structures
Abstract We prove that holomorphic continuations of functions in the classes an∗$\mathbf {an}^*$ and G$\mathcal {G}$ are definable in the o‐minimal structures Ran∗$\mathbb {R}_{\operatorname{an}^*}$ and RG$\mathbb {R}_{\mathcal {G}}$, respectively. More specifically, we give complex domains on which the holomorphic continuations are definable and show ...

Solver fast prototyping for reduct-based ELP semantics [PDF]
Over time, various semantic frameworks have emerged for Epistemic Logic Programs (ELPs), which extend Answer Set Programming (ASP) by incorporating epistemic operators.

We develop the ground‐motion characterization (GMC) for the 2025 U.S. National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands (NSHM‐PRVI) for earthquakes in active crustal, subduction interface, and subduction intraslab regimes. Using ground‐motion models (GMMs) from the Next‐Generation Attenuation (NGA)‐West2 and NGA‐Subduction ...

ABSTRACT Farm diversification provides alternative sources of income and helps mitigate risks associated with relying solely on one crop. This study investigated the impact of diversification on the welfare of Ghanaian cocoa farmers. Primary data were collected from 403 smallholder cocoa farmers using a multi‐stage sampling technique and analyzed using
