This study investigates pedagogical content knowledge (PCK) among teachers teaching mathematics at the preschool level in Colombia, highlighting the importance of integrating mathematical knowledge with innovative and effective pedagogical …

In this article, we are going to discuss about how alternant codes over Eisenstein integers are crucial in today’s technologies especially in encoding data and correction of those data. Based on the parity check matrices of alternant codes, the codes …

The development of critical thinking (CT) enhances academic and professional opportunities. A review of literature reveals the use of fragmented analysis techniques, such as descriptive and correlational methods, among others, which hinder a deeper …

Digitalization has recently gained significant relevance in the education field. The focus has been on its use and application, as well as on training teachers and students to become responsible, competent, and ethical users of technology. This is …

This study analyzes in a comparative way the psychological meanings that social science and basic science researchers assign to the term "research". Using the Natural Semantic Networks technique with 127 participants from a Colombian public …

We investigate the spectral types of families of discrete one-dimensional Schrödinger operators $\{H_{\omega }{\}}_{\omega \in \mathrm{\Omega }}$, where each $H_{\omega }$ has a potential function $V_{\omega }(n)=f(T^n\omega )$ for $n\in \mathbb{Z}$, $T$ is an ergodic …

This paper is dedicated to study some pseudo-differential equations related to the operator $D_{d_1,d_2}^{\alpha }$ with symbol ${\mathcal{A}}_{d_1,d_2}^{\alpha }=max|x{|}_p^{d_1},|x{|}_p^{d_2}$, acting on a radial function $\phi (|x{|}_p)$. The …

In block ciphers, the nonlinear components, also known as sub- stitution boxes (S-boxes), are used with the purpose of inducing confusion in cryptosystems. For the last decade, most of the work on designing S-boxes over the points of elliptic curves …

La violencia es un flagelo social que campea por todos los escenarios y se requieren esfuerzos multilaterales y variadas estrategias para combatirla. El objetivo de este trabajo investigativo fue aplicar una estrategia de juegos cooperativos para …

In this paper, we apply the method given in the paper “Zero relaxation time limits to a hydrodynamic model of two carrier types for semiconductors” (Mathematische Annalen, 2022, 382: 1031–1046) to study the Cauchy problem for a one dimensional …
