THE LATTICE OF CONGRUENCES ON A TERNARY SEMIGROUP [PDF]

open access: yesJournal of Algebraic Systems, 2018
In this paper we investigate some properties of congruences on ternary semigroups. We also define the notion of congruence on a ternary semigroup generated by a relation and we determine the method of obtaining a congruence on a ternary semigroup T from a

Cladistics and Stratigraphy

open access: yesGeosciences, 2023
Using cladistic phylogenies (cladograms) to evaluate stratigraphy (taxon distributions and correlations) necessitates various assumptions that include all of the assumptions built into the cladogram, assuming the cladogram is “correct” and that new taxa ...

Double Flash Illusions: Current Findings and Future Directions

open access: yesFrontiers in Neuroscience, 2020
Twenty years ago, the first report on the sound-induced double flash illusion, a visual illusion induced by sound, was published. In this paradigm, participants are presented with different numbers of auditory and visual stimuli.

Robustness Analysis of Deep Learning-Based Lung Cancer Classification Using Explainable Methods

open access: yesIEEE Access, 2022
Deep Learning (DL) based classification algorithms have been shown to achieve top results in clinical diagnosis, namely with lung cancer datasets. However, the complexity and opaqueness of the models together with the still scant training datasets call ...

Congruence submodularity

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2002
A lattice \(L\) of equivalence relations on a set \(A\neq \emptyset\) is called \(k\)-submodular \((k\geqq 2\) being a positive integer) if for all \(\theta, \phi, \psi \in L\) with \(\theta \subseteq \psi\) the condition \((\theta,\phi,\theta \dots)\cap \psi\subseteq \theta \vee (\phi\vee \psi)\) (where in the brackets on the left side there are \(k\)

PRINCIPAL AND SYNTACTIC CONGRUENCES IN CONGRUENCE-DISTRIBUTIVE AND CONGRUENCE-PERMUTABLE VARIETIES [PDF]

open access: yesJournal of the Australian Mathematical Society, 2008
AbstractWe give a new proof that a finitely generated congruence-distributive variety has finitely determined syntactic congruences (or, equivalently, term finite principal congruences), and show that the same does not hold for finitely generated congruence-permutable varieties, even under the additional assumption that the variety is residually very ...

Impact of Interest Congruence on Study Outcomes

open access: yesFrontiers in Psychology, 2022
Grounding on Holland’s RIASEC model of vocational interests and the respective assumptions on person-environment fit (congruence), this paper focuses on how congruence is related to study outcomes, especially students’ persistence, performance, and ...

Canonical forms for unitary congruence and *congruence [PDF]

open access: yesLinear and Multilinear Algebra, 2009
We use methods of the general theory of congruence and *congruence for complex matrices--regularization and cosquares-to determine a unitary congruence canonical form (respectively, a unitary *congruence canonical form) for complex matrices A such that \bar{A}A (respectively, A^2) is normal.
