On Implicative and Positive Implicative GE Algebras

open access: yesBulletin of the Section of Logic, 2023
GE algebras (generalized exchange algebras), transitive GE algebras (tGE algebras, for short) and aGE algebras (that is, GE algebras verifying the antisymmetry) are a generalization of Hilbert algebras. Here some properties and characterizations of these

Positive implicative ordered filters of implicative semigroups [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We introduce the notion of positive implicative ordered filters in implicative semigroups. We show that every positive implicative ordered filter is both an ordered filter and an implicative ordered filter. We give examples that an ordered filter (an implicative ordered filter) may not be a positive implicative ordered filter.

Implications of positive surgical margins [PDF]

open access: yesThe Laryngoscope, 1993
AbstractThe recently concluded Head and Neck Intergroup trial tested the addition of three courses of cis‐platinum containing chemotherapy to standard treatment of surgery and postoperative radiotherapy for patients with advanced operable squamous cell carcinoma of the head and neck.

HLA-B27 positivity: associated health implications [PDF]

open access: yesInternational Journal of Ophthalmic Practice, 2011
HLA-B27 positivity makes the onset of autoimmune diseases such as uveitis, ankylosing spondylitis and Crohn's disease more likely to occur. Ankylosing spondylitis and Crohn's disease are two types of HLA-B27 positive diseases that demonstrate a direct association with uveitis.

General Implicativity in Groupoids

open access: yesMathematics, 2018
There are several equivalent axioms, which can be used to characterize the positive implicativity in B C K -algebras. In this paper, we investigate interrelationships among such axioms in a more general setting of groupoids, and several aspects ...

Fuzzy positive implicative ordered filters of implicative semigroups [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We consider the fuzzification of the notion of a positive implicative ordered filter in implicative semigroups. We show that every fuzzy positive implicative ordered filter is both a fuzzy ordered filter and a fuzzy implicative ordered filter. We give examples that a fuzzy (implicative) ordered filter may not be a fuzzy positive implicative ordered ...

Positive Implicative-Artinian and Positive Implicative Noetherian Hyper Bck-Algebras

open access: yesUniversal Journal of Computational Mathematics, 2014
The notion of intuitionistic fuzzy positive implicative hyper BCK-ideals of type-1, 2... 8 of hyper BCK-algebras was introduced in 2012 by Durga Prasad, Satyanarayana and Ramesh. In this paper, we investigate some related properties of intuitionistic fuzzy positive implicative hyper BCK-ideals of types-1.

Weak positive implicative hyperBCK-ideal [PDF]

open access: yesJournal of Korean Institute of Intelligent Systems, 2003
In this paper we define a weak positive implicative hyperBCK-ideal of hyperBCK-algebra. Also we investigate that every positive implicative hyperBCK-algebra is a positive implicative hyperK-algebra and then we prove that every positive implicative hyperK-algebra is a weak positive implicative hyperK-algebra.

Positive Tetrahydrocurcumin-Associated Brain-Related Metabolomic Implications

open access: yesMolecules, 2023
Tetrahydrocurcumin (THC) is a metabolite of curcumin (CUR). It shares many of CUR’s beneficial biological activities in addition to being more water-soluble, chemically stable, and bioavailable compared to CUR. However, its mechanisms of action have not been fully elucidated. This paper addresses the preventive role of THC on various brain dysfunctions

On N-Fold Positive Implicative Artinian and Positive Implicative Notherian BCK-Algebras

open access: yesMathematics and Statistics, 2014
The notion of BCK-algebras was initiated by Imai and Iseki in 1966 as a generalization of both classical and non-classical positional calculus. In 1999, Huang and Chen introduced the notion of n-fold positive implicative ideals in BCK-algebras. In 2011, Satyanarayana and Durga Prasad introduced foldness of intuitionistic fuzzy positive implicative ...
