Topological bands in the PdSe2 pentagonal monolayer
The electronic structure of monolayer pentagonal palladium diselenide (PdSe2) is analyzed from the topological band theory perspective. Employing first-principles calculations, effective models and symmetry indicators, we ...
On fresh state behavior of foamed cement pastes and its influence on hardened performance
Foamed cement pastes or cellular cement pastes currently are a material of wide interest. The fresh state of these mixtures represents a critical point as it determines the properties on hardened state. Rheological ...
Narrow band filter designed from Bravais-Moiré two-dimensional photonic crystal
This work investigates the light propagation through a narrow-band filter based on a two-dimensional photonic crystal with Bravais-Moiré lattice and dielectric elements of circular cross section. We report on the corresponding ...

Modelling of an insurance premium through the application of actuarial methods, failure theory and Black-Scholes in the health in Colombia [Modelación de una prima de seguros mediante la aplicación de métodos actuariales, teoría de fallas y Black-Scholes en la salud en Colombia]
The pricing’s premium in an insurance for the health sector is influenced by the claims ratio of its subscribers, which generates high levels of fluctuation and uncertainty. The objective of this research is the application ...
A unified approach based on multidimensional scaling for calibration estimation in survey sampling with qualitative auxiliary information
Survey calibration is a widely used method to estimate the population mean or total score of a target variable, particularly in medical research. In this procedure, auxiliary information related to the variable of interest ...
