Assessing diversity of King Crab Lithodes spp. in the south‐eastern pacific using phylogeny and molecular species delimitation methods

Ecology and Evolution, 2022
The purpose of this study was to test the hypothesis that the genetic diversity of commercially significant species of King Crabs (Lithodes spp.) along the south‐eastern Pacific (SEP) comprises different independent evolutionary units (IEUs) with ...

(λ, μ)‐Fuzzy Version of Ideals, Interior Ideals, Quasi‐Ideals, and Bi‐Ideals [PDF]

Journal of Applied Mathematics, 2012
We introduced (λ, μ)‐fuzzy ideals, (λ, μ)‐fuzzy interior ideals, (λ, μ)‐fuzzy quasi‐ideals, and (λ, μ)‐fuzzy bi‐ideals of an ordered semigroup and studied them. When λ = 0 and μ = 1, we meet the ordinary fuzzy ones. This paper can be seen as a generalization of Kehayopulu and Tsingelis (2006), Kehayopulu and Tsingelis (2007), and Yao (2009).

Bone grafts: which is the ideal biomaterial?

Journal of Clinical Periodontology, 2019
Bovine xenograft materials, followed by synthetic biomaterials, which unfortunately still lack documented predictability and clinical performance, dominate the market for the cranio-maxillofacial area. In Europe, new stringent regulations are expected to

Ideal Stabilization

2011 IEEE International Conference on Advanced Information Networking and Applications, 2011
We define and explore the concept of ideal stabilization. The program is ideally stabilizing if its every state is legitimate. Ideal stabilization allows the specification designer to prescribe with arbitrary degree of precision not only the fault-free program behavior but also its recovery operation.

Principal Ideals in the Ideal Lattice [PDF]

Proceedings of the American Mathematical Society, 1972
We show that there cannot be a definition of “principal elements” in the theory of multiplicative lattices so that the notion of principal elements concurs with the notion of principal ideals when interpreted in the ideal lattices of rings.
