Variantes raras do melanoma maligno: um desafio clínico e histopatológico
Parente, J; Gomes, J; Viana, I; Vale, EIntroduction: Malignant melanoma may present a great variety of histopathological patterns. Besides the classic forms of melanoma, there are a number of variants that have been described, such as polypoid, verrucous, desmoplastic, myxoid, chondroid, balloon-cell, rhabdoid, animal-type, amelanotic, spitzoid, nevoid. The aim of this study was to characterize the rare histopathologic variants of malignant melanoma...

Unified description of the DC conductivity of monolayer and bilayer graphene ba...
Ferreira, Aires; Nilsson, Johan; Castro Neto, A. H.; Gomes, J. Viana; Peres, N. M. R.We show that a coherent picture for the DC conductivity of monolayer and bilayer graphene emerges from considering that strong short-range potentials are the main source of scattering in these two systems. The origin of the strong short range potentials may lie in adsorbed hydrocarbons at the surface of graphene. The equivalence between results based on the partial wave description of scattering and the T-matri...
