An Injective Pseudo-BCI Algebra is Trivial [PDF]
Discussiones Mathematicae - General Algebra and Applications, 2019 Injective pseudo-BCI algebras are studied. There is shown that the only injective pseudo-BCI algebra is the trivial one.

An ordered structure of pseudo-BCI-algebras [PDF]
Mathematica Bohemica, 2016 To any pseudo-BCI-algebra [the reviewer and \textit{Y. B. Jun}, East Asian Math. J. 24, No. 2, 187--190 (2008; Zbl 1149.06010)], two binary operations (each of them being similar to that of a directoid) and a set of couples of antitone mappings is assigned which are in a certain sense mutually inverse.

Some properties of pseudo-BCI algebras [PDF]
Commentationes Mathematicae, 2019 Summary: The notion of an essential closed deductive system of a pseudo-BCI algebra is defined and investigated. Among other things, it is proved that such a deductive system contains all coatoms of the pseudo-BCI algebra. Also, the notions of homomorphisms and semihomomorphisms of pseudo-BCI algebras are studied and some of their properties are ...

On the generalization of pseudo p-closure in pseudo BCI-algebras [PDF]
Journal of HyperstructuresIn this paper, the notion of generalization of pseudo p-closure, denoted by gcl, is introduced and its related properties are investigated. The gcl of subalgebras and pseudo-ideals is discussed.

On two classes of pseudo-BCI-algebras [PDF]
Discussiones Mathematicae - General Algebra and Applications, 2011 The class of p-semisimple pseudo-BCI-algebras and the class of branchwise commutative pseudo-BCI-algebras are studied. It is proved that they form varieties.

Multi-granulation rough filters and rough fuzzy filters in Pseudo-BCI algebras
Journal of Intelligent & Fuzzy Systems, 2018 This paper introduced the notions of rough filters, multi-granulation rough filters, and rough fuzzy filters in pseudo-BCI algebras and investigated some properties. First, a congruence relation was structured by a filter on pseudo-BCI algebra. Then rough filters and rough fuzzy filters were investigated.

Human Brain Mapping, Volume 43, Issue 4, Page 1231-1255, March 2022., 2022 The electroencephalography–functional magnetic resonance imaging fusion methods that have been reported so far ignore the underlying multi‐way nature of the data in at least one of the modalities and/or rely on very strong assumptions concerning the relation of the respective datasets.
