Downstream Control on the Stability of River Bifurcations
Abstract River bifurcations are prevalent features in both gravel‐bed and sand‐bed fluvial systems, including braiding networks, anabranches and deltas. Therefore, gaining insight into their morphological evolution is important to understand the impact they have on the adjoining environment.

Engel, Nilpotent and Solvable BCI-algebras
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.

HEREDITARY SUBALGEBRAS OF BCK-ALGEBRAS
The leading motivation for BCK-algebras comes from algebraic logic: a BCK-algebra \({\mathbf A}= \langle A; \cdot, 0\rangle\) is the algebraic counterpart of a purely implicational calculus in which \(0\) corresponds to truth, \(x\cdot y\) is interpreted as \(y\to x\) and \(x\cdot y= 0\) as \(\lvdash y\to x\).

Quasi-valuation maps based on positive implicative ideals in BCK-algebras
The notion of PI-quasi-valuation maps of a BCK-algebra is introduced, and related properties are investigated. The relationship between an I-quasi-valuation map and a PI-quasivaluation map is examined.

An ordered structure of pseudo-{\rm BCI}-algebras [PDF]
In Chajda's paper (2014), to an arbitrary BCI-algebra the author assigned an ordered structure with one binary operation which possesses certain antitone mappings.

BMBJ-neutrosophic subalgebra in BCI/BCK-algebras [PDF]
For the first time Smarandache introduced neutrosophic sets which can be used as a mathematical tool for dealing with indeterminate and inconsistent information.

Factor congruences in BCK-algebras
In the paper under review, the authors present a general characterization of factor congruences in BCK-algebras, and use this description to determine whether a free algebra for a quasi-variety of BCK-algebras can be decomposed directly or not. In case it is decomposable, the authors determine its factors.

BCK-sequences and n-commutative BCK-algebras were introduced by T. Traczyk, together with two related problems. The first one, whether BCK-sequences are always prolongable.
