    In bioacoustics, passive acoustic monitoring of animals livingin the wild, both on land and underwater, leads to large dataarchives characterized by a strong imbalance between recordedanimal sounds and ambient noises. Bioacoustic datasets sufferextremely from such large noise-variety, caused by a multitudeof external influences and changing environmental conditionsover years. This leads to significant deficiencies/problems concerning the analysis and interpretation of animal vocalizationsby biologists and machine-learning algorithms. To counteractsuch huge noise diversity, it is essential to develop a denoisingprocedure enabling automated, efficient, and robust data enhancement. However, a fundamental problem is the lackof clean/denoised ground-truth samples. The current workis the first presenting a fully-automated deep denoising approach for bioacoustics, not requiring any clean ground-truth,together with one of the largest data archives recorded onkiller whales (Orcinus Orca) – the Orchive. Therefor, an approach, originally developed for image restoration, known asNoise2Noise (N2N), was transferred to the field of bioacoustics, and extended by using automatic machine-generated binary masks as additional network attention mechanism. Besidesa significant cross-domain signal enhancement, our previousresults regarding supervised orca/noise segmentation and orcacall type identification were outperformed by applying ORCACLEAN as additional data preprocessing/enhancement ste

    Journal non répertorié dans les bases de données internationales.International audienceIn this paper, we present a framework for understanding long-lasting influences on children's food purchase choices and consumption. The framework interacts the characteristics of agents (i.e., children and parents/caretakers) with marketing related effects to explain how these agents make short- and long-term decisions in the food category. We develop each of the components of our framework with different theories and multiple empirical examples, focusing on how children develop their food preferences and how their understanding of and resistance to persuasion and marketing messages may influence choices. Overall, the presented approach suggests firms, consumers, and parents can benefit from taking these factors into account when making choices that affect children and when allowing children to make their own choices

    RATIONALE: Several common and rare genetic variants have been associated with Idiopathic pulmonary fibrosis, a progressive fibrotic condition that is localized to the lung. OBJECTIVE: To develop an integrated understanding of the rare and common variants located in multiple loci that have been reported to contribute to the risk of disease. METHODS: We performed deep targeted resequencing (3.69 Mb of DNA) in cases (N=3,624) and controls (N=4,442) across genes and regions previously associated with disease. We tested for association between disease and a) individual common variants via logistic regression and b) groups of rare variants via a sequence kernel association test. MEASUREMENTS AND MAIN RESULTS: Statistically significant common variant association signals occurred in all 10 of the regions chosen based on genome-wide association studies. The strongest risk variant is the MUC5B promoter variant, rs35705950, with an OR of 5.45 (95% CI: 4.91-6.06) for one copy of the risk allele and 18.68 (95% CI: 13.34-26.17) for two copies of the risk allele (p=9.60 x 10-295). In addition to identifying for the first time that rare variation in FAM13A is associated with disease, we confirmed the role of rare variation in risk of IPF in the TERT and RTEL1 gene regions, and found that the FAM13A and TERT regions have independent common and rare variant signals. CONCLUSIONS: A limited number of common and rare variants contribute to the risk of idiopathic pulmonary fibrosis in each of the resequencing regions; these genetic variants focus on biological mechanisms of host defense and cell senescence
