1. Methodological approaches to planar and volumetric scintigraphic imaging of small volume targets with high spatial resolution and sensitivity
Single-photon emission computed tomography (SPECT) is a non-invasive imaging technique, which provides information reporting the functional states of tissues. SPECT imaging has been used as a diagnostic tool in several human disorders and can be used in animal models of diseases for physiopathological, genomic and drug discovery studies. However, most of the

2. Simulações do ruído de fundo instrumental e reconstrução de imagens do experimento protoMIRAX / Simulations of the instrumental background and image reconstruction of the protoMIRAX experiment
In this thesis, the results of detailed and realistic simulations performed with a Monte Carlo simulation code for gamma-ray Astronomy (MGGPOD) to predict the response of protoMIRAX are presented. The protoMIRAX is a project under development by the High Energy Astrophysics group of INPE, in which a hard X-ray camera is being built based on the coded apertur

3. Simulações do ruído de fundo instrumental e reconstrução de imagens do experimento protoMIRAX / Simulations of the instrumental background and image reconstruction of the protoMIRAX experiment
Neste trabalho apresenta-se o resultado de simulações computacionais realistas e detalhadas ealizadas com o programa MGGPOD, um conjunto de rotinas Monte Carlo que simula a interação da radiação gama com a matéria, para estimar a resposta do experimento protoMIRAX ao campo externo de radiação. O protoMIRAX é um projeto do grupo de Astrofísica de A

4. Da epidemiologia para a neurociÃncia: entendendo NeurÃnios disparantes acoplados eletricamente atravÃs do Modelo sirs estocÃstico na rede hipercÃbica
The response function of individual sensory spiking neurons (ring rate vs. stimulus intensity) has a small dynamic range. For example, in olfactory sensory neurons, only ~ 10 dB of stimulus intensity can be reasonably coded, if saturation and low-stimulus noise were to be avoided. This is in stark contrast with the large dynamic range observed in the next sy
