Public health care systems in these areas face many problems like isolation, scarce of communication infrastructures or lack of personnel with adequate training that may be solved through the use of appropriate ICTs. This chapter presents a case study of the more than ten years of EHAS (Enlace Hispano Americano de Salud Hispano American Health Link) Foundation activities trying to solve this pr...

We investigate lattice dynamics and spin-phonon coupling as well the magnetic electronic properties of $\ensuremath{\beta}\text{\ensuremath{-}}{\mathrm{Na}}_{0.33}{\mathrm{V}}_{2}{\mathrm{O}}_{5}$ using temperature-dependent Raman scattering, dc magnetization resistivity, x-ray photoemission, absorption spectroscopy. The Rietveld refinement diffraction pattern with space group $C2/m$ confirms m...

We introduce a double quantum (DQ) 4-Ramsey measurement protocol that enables wide-field magnetic imaging using nitrogen-vacancy ($\mathrm{N}$-$V$) centers in diamond, with enhanced homogeneity of the sensitivity relative to conventional single (SQ) techniques. The DQ employs microwave-phase alternation across four consecutive Ramsey (4-Ramsey) measurements isolate desired signal from any resid...

In this paper we introduce two project evolution indicators. One is showing an increase of downloads of the project and therefore a growing interest of users in the results of the project. The second indicator is predicting the future evolution of the project with the submission of new revisions to the concurrent versioning system. Both indicators can provide evidence of the sustainability of a...

A key trait of Free and Open Source Software (foss) development is its distributed nature. Nevertheless, two projectlevel operations, the fork and the merge of program code, are among the least well understood events in the lifespan of a foss project. Some projects have explicitly adopted these operations as the primary means of concurrent development. In this study, we examine the effect of hi...

Recent studies have been trying to better understand geographically distributed software development which is increasing from year to year. Analyzing Free/Open Source Software (FOSS) communities would help us obtain useful insights for distributed software development, because some FOSS communities already have tremendous success in a distributed environment. Our prior study analyzed an informa...
