L- and Θ-curve approaches for the selection of regularization parameter in geophysical diffraction tomography
(2007)
Since inverse problems are usually ill-posed it is necessary to use some method to reduce their deficiencies. The method that we choose is the regularization by derivative matrices. When a first derivative matrix is used ...
Crystal structure determination of karibibite, an Fe3+ arsenite, using electron diffraction tomography
(Mineralogical Soc, 2017-10)
The crystal structure of karibibite, Fe3+3 (As3+O2)4(As3+2 O5)(OH), from the Urucum mine (Minas Gerais, Brazil), was solved and refined from electron diffraction tomography data [R1 = 18.8% for F > 4σ(F)] and further ...
