Full textArtificial intelligence (AI) has been widely used in the research field of AI-assisted diagnosis, treatment, and personalized medicine. This manuscript focuses on the application of artificial intelligence methods including deep learning and radiomics in cancer diagnosis. First, effective image segmentation is essential for cancer diagnosis and further radiomics-based analysis. We proposed a new approach for automatic lesion segmentation in ultrasound images, based on a multicentric and multipathology dataset displaying different types of cancers. By introducing the group convolution, we proposed a lightweight U-net network without sacrificing the segmentation performance. Second, we processed the clinical Magnetic Resonance Imaging (MRI) images to noninvasively predict the glioma subtype as defined by the tumor grade, isocitrate dehydrogenase (IDH) mutation and 1p/19q codeletion status. We proposed a radiomics-based approach. The prediction performance improved significantly by tuning different settings in the radiomics pipeline. The characteristics of the radiomic features that best distinguish the glioma subtypes were also analyzed. This work not only provided a radiomics pipeline that works well for predicting the glioma subtype, but it also contributed to the model development and interpretability. Third, we tackled the challenge of reproducibility in radiomics methods. We investigated the impact of different image preprocessing methods and harmonization methods (including intensity normalization and ComBat harmonization) on the radiomic feature reproducibility in MRI radiomics. The conclusion showed that ComBat method is essential to remove the nonbiological variation caused by different image acquisition settings (namely, scanner effects) and improve the feature reproducibility in radiomics studies. Meanwhile, intensity normalization is also recommended because it leads to more comparable MRI images and more robust harmonization results. Finally, we investigated improving the ComBat harmonization method by changing its assumption to a very common case that scanner effects are different for different classes (like tumors and normal tissues). Although the proposed model yielded disappointing results, surely due to the lack of enough proper constraints to help identify the parameters, it still paved the way for the development of new harmonization methods

Full textShifting cultivation on brulis (ai) is a convenient method of cultivation without inputs. After two or three crop cycles, the degradation of soil fertility forces farmers to move their crops and the land is left fallow. Fallowing can be used to reconstitute a biomass, which will release during the next production period, after burning, the mineral elements necessary for the growth and development of crops. The purpose of this study was to provide support for the decision, with a view to eventually establishing these traditional systems. It required an analysis of the management of Qi systems, an important component of reproducibility of fertility, and the condition of fixation. At first, the spatial management of these systems and their capacity to cope with the agro-ecological and socio-economic constraints of the environment, to reproduce, were studied. This study was carried out at the scale of the agrarian system and more precisely at the level of the production systems which correspond to the level of the choices and decisions of the farmers. In a second step, the evolution of the components of fertility, likely to influence the yield of cassava, was analyzed - the cassava constituting the main crop of West Guiana. Three levels were considered: the cropping system that allows to understand the modes of behavior and association of crops, but especially the cultivated plot and the experimental plot, place of measurement and monitoring. In the first stage of this work, a balancing capacity of the giblets is established from the Piaget model. This typology makes it possible to identify 5 functional types of giblets in the region and 2 modes of evolution. In the second stage, during a first cycle of giblets, after secondary forest, the evolution of stocks of carbon, nitrogen and exchangeable bases shows that there is no degradation in relation to the material organic soil. On the other hand, there is a decrease in exchangeable bases following the cultivation and in particular potassium. Comparing this decrease with the needs of the crop, it was possible to identify potassium as a factor limiting production
