Background Chagas disease is caused by Trypanosoma cruzi , and humans acquire the parasite by exposure to contaminated feces from hematophagous insect vectors known as triatomines. Triatoma virus (TrV) is the sole viral pathogen of triatomines, and is transmitted among insects through the fecal-oral route and, as it happens with T. cruzi, the infected insects release the virus...
A study of the physics of electronic states in cubic InAs quantum dot periodic nanostructures embedded in GaAs is presented. The miniband structure of electron states in the conduction band is related to the size and density of the quantum dots. The effect of strain is also taken into account in the simulations. The photon-electron absorption coefficient is obtained for different quantum dot configurations...
In this work, a study of traps located in the bulk and the Si-SiO2 interfaces of four gate transistors (G4-FETs), and their effect in the performance of these transistors, is presented. Different kinds of low frequency noise spectra measured at different voltages applied to the gates show that traps in the bulk and traps at the interfaces are the origin of such different spectra. We propose a model...
