In several signal processing applications for wireless communications, the received signal is multidimensional in nature and may exhibit a multilinear algebraic structure. In this context, the PARAFAC tensor decomposition has been the subject of several works in the past six years. However, generalized tensor decompositions are necessary for covering a(More)
The most used treatment strategies for breast cancer (BC) are surgery, chemotherapy, and/or radiotherapy. Premenopausal women undergoing adjuvant chemotherapy BC treatment have significant bone loss from the first year after the treatment. This high bone mineral density loss can lead to an increased risk of fractures. Doxorubicin associated with(More)
PURPOSE To determine the effects of different polychemotherapy drugs on cortical bone structure, the femur diaphysis of rats were treated with two different chemotherapy drugs, AC (doxorubicin + cyclophosphamide) and TC (docetaxel + cyclophosphamide), and evaluated by 3D morphological analysis using synchrotron radiation microtomography. MATERIALS AND(More)
Synchrotron Radiation (SR) X-ray micro-Computed Tomography (mCT) enables magnified images to be used as a non-invasive and non-destructive technique with a high space resolution for the qualitative and quantitative analyses of biomedical samples. The research on applications of segmentation algorithms to SR-mCT is an open problem, due to the interesting and(More)
The PhC-SR-μCT is a nondestructive technique that allows the microanatomical investigations and 3D images reconstructions within a short time. This technique performed in blood sucker, Rhodnius prolixus – one of the most important primary vectors of of Trypanosoma cruzi, ethiologic agent of Chagas’ disease in Latin America and also the most well-know(More)
