From an algebraic construction of the mKdV hierarchy we observe that the space component of the Lax operator plays the role of a universal algebraic object. This fact induces the universality of a gauge transformation that ...

A comparative study was used to outline the literature in the research topic. This paper aims to present a bibliometric study of multi-criteria decision-making methods most applied in publications from 1990 to 2014. Our ...

Current Internet-based technologies enable the operation of extended supply chains (ESCs) and introduce new requirements on managing and sharing product-related information in such ESCs, where product models are the ...

Values are at the heart of human decision-making. They are used to decide whether something or some state of affairs is good or not, and they arealso used to address the moral dilemma of the right thing to do under given ...

The purpose of this research was to compare the hierarchy of values among high school students, according to type of school (religious and secular) and sex. The sample was composed by 250 high school students (60.4% male, ...

Different gauge copies of the Ablowitz-Kaup-Newell-Segur (AKNS) model labeled by an angle θ are constructed and then reduced to the two-component Camassa-Holm model. Only three different independent classes of reductions ...

We investigate a two scalar field split braneworld model which leads to a possible approach to the hierarchy problem within the thick brane scenario. The model exhibits a resulting asymmetric warp factor suitable for this ...

We propose an approach to the nonvanishing boundary value problem for integrable hierarchies based on the dressing method. Then we apply the method to the AKNS hierarchy. The solutions are found by introducing appropriate ...
