A calculation of the physical mass of sigma meson
Published 2007“…The mass is calculated by using the spectral function, and we find that it is about 600 MeV. In addition, we obtained 220 MeV as the value for the width of its spectral function. …”

Remittances and the household's expenditures on health
Published 2009“…We use a Tobit model with random effects and find a statistically significant effect of remittances on the proportion of health expenditures for households that do not have access to employment’s medical insurance: Our results suggest that around 10% of changes in remittances are devoted to health expenditure…”

Performance evaluation and optimization of swarms of robots in a specific task
Published 2019“…However, determining how well the task is resolved is an important current problem, assign evaluation metrics to tasks performed by swarms of robots is very useful in order to measure the performance of a particular swarm in the task resolution. Find the control parameters of a swarm of robots that resolves a task with the best possible performance represents many benefits as saving of energetic resources and time. …”

All you can drink: should we worry about quality?
Published 2009“…In this paper, I elaborate a model to determine whether a monopolist produces higher or lower quality goods when using buffet pricing (all you can drink) instead of a two-part tariff. I find that the more profitable strategy is usually associated with a higher quality good than the less profitable strategy. …”
