A Novel DOI Positioning Algorithm for Monolithic Scintillator Crystals in PET Based on Gradient Tree Boosting [PDF]
IEEE Transactions on Radiation and Plasma Medical Sciences, 2018 Monolithic crystals are examined as an alternative to segmented scintillator arrays in positron emission tomography (PET). Monoliths provide good energy, timing, and spatial resolution including intrinsic depth of interaction (DOI) encoding.

São Paulo em Perspectiva, 2002 Da dupla perspectiva das "alianças" e do Modo de Reprodução Ampliada do Capital (MRAC), as alianças são vantajosas apenas quando os países que as fazem estão no mesmo grau de maturação do MRAC, ou contribuem para que novos associados atinjam o estágio dos mais desenvolvidos. O acordo do Mercosul igualou do mais forte aos mais fracos.

Response of Single Polymers to Localized Step Strains [PDF]
, 2008 In this paper, the response of single three-dimensional phantom and self-avoiding polymers to localized step strains are studied for two cases in the absence of hydrodynamic interactions: (i) polymers tethered at one end with the strain created at the ...
