On Implicative and Positive Implicative GE Algebras [PDF]

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

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 ...

On Pre-Hilbert and Positive Implicative Pre-Hilbert Algebras [PDF]

open access: yesBulletin of the Section of Logic
In the paper, pre-Hilbert algebras are defined as a generalization of Hilbert algebras (namely, a Hilbert algebra is just a pre-Hilbert algebra satisfying the property of antisymmetry).

Neutrosophic Positive Implicative N -Ideals in BCK-Algebras [PDF]

open access: yesAxioms, 2018
The notion of a neutrosophic positive implicative N -ideal in B C K -algebras is introduced, and several properties are investigated. Relations between a neutrosophic N -ideal and a neutrosophic positive implicative N -ideal are discussed.

Capivasertib in Hormone Receptor-Positive Advanced Breast Cancer.

open access: yesNew England Journal of Medicine, 2023
BACKGROUND AKT pathway activation is implicated in endocrine-therapy resistance. Data on the efficacy and safety of the AKT inhibitor capivasertib, as an addition to fulvestrant therapy, in patients with hormone receptor-positive advanced breast cancer ...

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.

Pooled CRISPR screening identifies m6A as a positive regulator of macrophage activation

open access: yesScience Advances, 2021
CRISPR screening identifies RNA m6A modification as negative regulator of TLR signaling pathway for proper innate immune response. m6A RNA modification is implicated in multiple cellular responses.

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.

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 ...
