Full textCortical bone and dentine are two biological tissues sharing a common genetic origin, overall structure, composition, and embryological development, distinct from those of enamel. Various observations suggest the possibility of coordinated postnatal development of these two tissues in hominins. For example, Neandertals display higher cortical bone volumes in their infra-cranial skeleton and greater dentine robustness compared to modern humans, while absolute enamel volumes are similar between the two taxa. Studies of immature Neandertal specimens indicate that their cortical bone and dentine robustness may be present from early developmental stages. In this doctoral research, we aimed to understand whether the structural and developmental affinities between cortical bone and dentine could lead to coordinated postnatal development of these tissues in modern humans. To this end, we measured the coordinated variation of cortical bone and dentine volumes in a sample of modern humans, comprising 12 immature individuals and 70 adults. Using microtomographic acquisitions of the arm, forearm bones, and anterior dentition, we conducted a methodological approach combining the quantification of cortical bone and dentine volumes with the analysis of their topographic distribution. Our results highlight a developmental desynchronization between cortical bone and dentine during the growth of immature individuals, leading to weak covariation between their cortical bone and dentine volumes. The bone-dentine covariation signal is stronger in adults, suggesting that common factors may influence postnatal development of these tissues once skeletal and dental maturation is achieved. This research highlights the predominant role of the hormonal milieu in the postnatal development of these tissues, while the biomechanical history of the skeleton appears to have a more limited impact. A preliminary analysis of bone-dentine covariation was conducted on chimeric individuals of Paranthropus, Australopithecus, and Neandertals. Most of these individuals deviate from the modern human bone-dentine relationship, characterized by higher dentine volumes in fossil taxa and cortical bone volumes similar to those of modern humans. A slowdown in growth and development has been described in Homo sapiens compared to fossil hominins, which may explain the unique bone-dentine relationship seen in this taxon. This doctoral thesis provides an original contribution to the study of bone and dental tissue volumes and distribution in various fossil and extant hominin taxa, offering insights into the impact of genetic, environmental, and evolutionary factors acting on their development

Full textAeolian dunes at different scales (m-km) are the primary topographic forms in aeolian systems and are found on various planetary bodies such as Earth, Mars, or Venus. They result from the interaction between wind, transported sediments, and the substrate. The shape, size, spatial arrangement, and movement of dunes allow for the analysis of interactions between airflows and sediment supply, modulated by surface conditions. The production of detailed maps of individual dune characteristics, coupled with spatial morphometric statistical analysis, is thus necessary to understand better and characterize the origin of dune formation and evolution.However, accurately mapping dunes over large areas remains a challenging task today for two reasons. Firstly, considering the availability of remote sensing datasets with ever-increasing spatial (and temporal) resolution, such mapping requires automated processes since manual digitization i) is time-consuming and ii) can be subjective and of uneven quality. These limitations are mainly because human operators cannot maintain consistent mapping criteria across large study areas, especially when dealing with complex morphologies. Secondly, this mapping is challenging, particularly due to the complexity of some forms and the lack of a universally accepted dune classification, despite recent research efforts.The primary objective of this work is to propose a new method for mapping aeolian dunes, focusing on an approach that couples Deep Learning to delineate the dune outlines, "skeletonization," and network analysis to map their crestlines and connectivities (defects). The originality of this study lies in the ability to map these features at various scales, ranging from a few kilometers to entire deserts. The developed algorithms demonstrate excellent performance in analyzing large and complex geographic areas with an accuracy of around 90%. This method has enabled the creation, for the first time, of a database containing several thousand dunes from the Rub'Al Khali desert (the largest active desert in the world), with high fidelity compared to visual observations of the dunes present in the Digital Elevation Model (DEM).From this database, we studied the morphological variability of the dunes by comparing them with wind data (ERA5 Land Reanalysis) on a desert scale, in order to quantify and understand their morphological changes and spatial distributions in relation to wind dynamics. This spatialized morphometric analysis is based on Principal Component Analysis (PCA) and highlights the dominant parameters as follows: dune length (PC1) explains more than 50% of the variance and describes the linear dunes in the SW of the desert; height (PC2) represents 18% of the variance and describes the crescent-shaped dunes in the NW; and defect density (PC3) explains 14% of the variance, representing star and dome dunes in the SE. P-value tests were also conducted on these parameters and revealed values below 0.05, thus confirming a significant spatial organization of dunes at the desert scale.Each archetypal dune form is dominated by one of the three parameters identified by the PCA, and transitions between these forms represent evolutionary stages. By comparing these results with wind data, we obtain an evolutionary model in which dunes shape, size, and orientation are strongly influenced by the directional characteristics of sand flow associated with the Shamal and Kharif winds. The analysis of wind data to the different statistically defined dune populations also revealed two dune growth modes: an elongation mode in the west, where the crests of linear dunes align with the sediment flow, favoring their stretching, and an instability mode in the east, where isolated and crescentic dunes, perpendicular to the flow, optimize their vertical growth

Full textMinkowski functionals define set topological and geometrical measurements, insufficient for the characterization, because different sets may have the same functionals. Thus, other shape functionals, geometrical and morphometrical are used. A shape diagram, defined thanks to two morphometrical functionals, provides a representation allowing the study of set shapes. In quantitative image analysis, these functionals and diagrams are often limited to binary images and achieved in a global and monoscale way. The General Adaptive Neighborhoods (GANs) simultaneously adaptive with the analyzing scales, the spatial structures and the image intensities, enable to overcome these limitations. The GAN-based Minkowski functionals are introduced, which allow a gray-tone image analysis to be realized in a local, adaptive and multiscale way.The GANs, defined around each point of the spatial support of a gray-tone image, are homogeneous with respect to an analyzing criterion function represented in an algebraic model, according to an homogeneity tolerance. The shape functionals computed on the GAN of each point of the spatial support of the image, define the so-called GAN-based shape maps. The map histograms and diagrams provide statistical distributions of the shape of the gray-tone image local structures, contrary to the classical histogram that provides a global distribution of image intensities. The impact of axiomatic criteria variations is analyzed through these maps, histograms and diagrams. Thus, multiscale maps are built, defining GAN-based shape functions
