Challenges to the ancient methane seep search strategy: The Bedford Canyon Formation (Middle Jurassic, Santa Ana Mountains, California)

open access: yesSedimentology, Volume 72, Issue 2, Page 688-707, February 2025.
Abstract Carbonates formed by anaerobic oxidation of methane at localized seeps have been recognized in the rock record based on a list of criteria, including anomalous deposition within detrital facies, complex petrofabrics, seep‐endemic macrofauna and 13C‐depleted isotopic signatures.

Engel, Nilpotent and Solvable BCI-algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this paper, we define the concepts of Engel, nilpotent and solvable BCI-algebras and investigate some of their properties. Specially, we prove that any BCK-algebra is a 2-Engel.

Multipolar Intuitionistic Fuzzy Set with Finite Degree and Its Application in BCK/BCI-Algebras

open access: yesMathematics, 2020
When events occur in everyday life, it is sometimes advantageous to approach them in two directions to find a solution for them. As a mathematical tool to handle these things, we can consider the intuitionistic fuzzy set. However, when events are complex

Benchmarking Multipartite Entanglement Generation with Graph States

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 1, January 2025.
As quantum computing technology matures, interest in assessing the capabilities of quantum hardware grows. This study discusses benchmarking entanglement generation in noisy intermediate‐scale quantum (NISQ) devices using graph states. Entanglement witnesses are used to detect bipartite and multipartite entanglement in graph states for two‐colorable ...

Safety Containment Control for Parabolic PDEs

open access: yesIET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This paper investigates the output feedback containment control problem for multi‐agent systems with multiple leaders under denial‐of‐service attacks. In the considered system, all agents are modelled by partial differential equations. ABSTRACT This paper investigates the output feedback containment control problem for multi‐agent systems (MASs) with ...

Study of Cubic Q-ideals in Q-algebras

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
The concept of cubic ideals is an important generalization in an algebraic structure. In this work, we introduce the notion of a cubic Q-sub-algebra and a cubic Q-ideal within a Q-algebra.

On n-fold fuzzy positive implicative ideals of BCK-algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider the fuzzification of the notion of an n-fold positive implicative ideal. We give characterizations of an n-fold fuzzy positive implicative ideal.

Positive Implicative Hyper BCK-Ideals of Hyper BCK-Algebras Under an Interval-Valued Intuitionistic Fuzzy Environment

open access: yesInternational Journal of Analysis and Applications
This paper contains some new theorems related to hyper BCK-ideals positive implicative hyper BCK-ideals of types-1, 2, 3, 4 of hyper BCK-algebras (HBCKA) under an interval-valued intuitionistic fuzzy environment. Henceforth, the connection between these ideas and their relevant characteristics is discussed.

On Pseudo implicative BCK ideals of Pseudo-BCK algebras

open access: yes, 2009
W.A. Dudek and Y.B. Jun gave a characterization of pseudo-BCK algebras, and provided conditions for a pseudo-BCK algebra to be ^-semi- lattice ordered (resp. \-semilattice ordered). Y.B. Jun, M. Kondo and K.H. Kim, introduced the notion of positive implicative pseudo-ideals in a pseudo-BCK algebra, and then they investigated some of their properties ...
