Full textStatistical depth functions play a fundamental role in analyzing and characterizing complex data structures. Depth functions provide a measure of centrality or outlyingness for individual observations or entire datasets, aiding in the understanding of their relative positions and underlying distributions. The concepts related to depth, as found in the literature, originate from the notion of Tukey's depth, also known as the median depth. This concept was introduced by the statistician John W. Tukey in his article titled "Mathematics and the Picturing of Data," published in 1975 [170]. The fundamental idea underlying Tukey's depth is to generalize the univariate median of a one-dimensional dataset in higher dimension. First, our interest focuses on multivariate depths followed by functional depths, both of which we build an overall review within Chapter 1. In the second part of this thesis, i.e. in Chapter 2, we undertake a rigorous study of multivariate depth-level sets and establish several analytical and statistical properties. First, we show that, when the underlying multivariate depth is smooth enough, then the symmetric difference between the estimated depth-level set and its theoretical counterpart converges to zero in terms of the d-dimensional volume and of the probability under the unknown distribution. Apart from these contributions, the novelty of Chapter 2 is the introduction and study of a depth-based risk measure called the Covariate-Conditional- Tail-Expectation (CCTE), within a risk theory setup. Roughly, the CCTE aims at computing an average cost knowing that at least one of the risk factors at hand is 'high' in some direction. The latter risk area is modelled by a level-set of low depth value. In contrast to risk measures based on distribution tails, our definition of CCTE is direction-free, owing to the involvement of depth level sets. We establish that, as the sample size goes to infinity the empirical depth-based CCTE is consistent for its theoretical version. We demonstrate consistency and provide rates of convergence for the depth- CCTE, for fixed levels of risk as well as when the risk level goes to zero as the sample size goes to infinity. In this last case of study, we also analyze the behavior of the original CCTE definition based on a distribution function, a case that was not studied in [56]. On top of several simulations performed on the CCTE, we illustrate its usefulness on environmental data.The final part of this thesis, Chapter 3, wraps up our work in which we contribute to defining a new type of depth for functional data based on functional principal component analysis. This includes using a generic multivariate depth. In this view, we use the well known Karhunen-Loève decomposition as a tool to project a centered square-integrable random process along some finite linear combination of orthogonal functions called the principal components. To the best of our knowledge, this is a novel approach in the functional depth literature. In this extent, we involve a multivariate depth function for the vector of the projected principal components. Naturally, we provide an estimator of our functional depth for which we demonstrate uniform consistency with a rate of convergence. We complement our study with several simulations and real data applications to functional classification, where our new depth equals or outperforms most of conventional competitors

Full textProving that programs behave correctly is difficult; one uses proof tools, which must rely on overapproximation (because of Rice's theorem). Automaton completion is such a tool, which overapproximates the set of reachable terms during the execution of a program represented as a TRS. An evaluation strategy dictates which subterm of a term should be rewritten first; taking this into account allows for a better approximation. Our thesis sets forward an adaptation of automaton completion to the innermost strategy, which is used among others by OCaml. We prove the soundness and the precision of our adaptation and show how it is part of a greater framework for analysis of functional programms (OCaml)

Full textOne of the greatest challenges of modern neuroscience that will lead to a better understanding and earlier diagnostics of brain sickness is to decipher the details of neuronal interactions in the living brain. To achieve this goal, we must be capable of observing populations of living cells in their original matrix with a good resolution, both spatial and temporal. Two-photon microscopy offers the right tools for this since it presents with a spatial resolution in the order of the micron. Unfortunately, this very good three-dimensional resolution lowers the temporal resolution because the optical sectioning caused by the microscope's small depth of field forces us to scan thick samples repeatedly when acquiring data from a large volume. In this doctoral project, we have designed, built and characterized a two-photon microscope with an extended depth of field with the goal of simplifying the functional imaging of neurons in thick samples. To increase the laser scanning microscope's depth of field, we shaped the laser beam entering the optical system in such a way that a needle of light is generated inside the sample instead of a spot. We modify the laser beam with an axicon, a cone-shaped lens that transforms a gaussian beam into a quasi non-diffractive beam called Bessel-Gauss beam. The excitation beam therefore maintains the same transverse resolution at different depths inside the sample, eliminating the need for many scans in order to probe the entire volume of interest. In this thesis, we demonstrate that the extended depth of field microscope effectively works as we designed it, and we use it to image calcium dynamics in a three-dimensional network of live neurons. We also present the different advantages of our system in comparison with standard two-photon microscopy.

Full textOur knowledge of the diversity of marine microbial communities has long been restricted to the precious but incomplete informations generated by the culture-based methods. In this study, molecular techniques (PCR, RT-PCR, cloning, sequencing, hybridization) and genetic markers [16S rRNA, genes coding for enzymes specific of diverse metabolic pathways (mcr A, pmo A, dsrAB)] were used to circumvent the limits inherent to cultivation methods ant to get a more realistic view of the specific and functional diversity of the deep-sea hydrothermal vent microbial communities. This research allowed (i) to reveal a wide diversity af archaeal and bacterial 16S rRNA, and to show the existence of variations in the archaeal coomunity composition at the hydrothermal site and hydrothermal field scales, (ii) to discover new microbial lineages whatever the genetic markers used, and to study the phylogenetic diversity and geopgraphic distribution of one of them (iii) to develop and validate 16S rRNA oligonucleotide probes targeting Archaea frequently found in hydrothermal systems, and (iv) to identify the most active Archaea of a microbial community associated with an hydrothermal sample. By the combined use of diverse molecular approaches, this work enlarges our view of the diversity of microbial communities in deep-sea hydrothermal vents

Full textThe dorsal horn of the spinal cord (Dh) is organized into different laminae. Each lamina is characterized by the presence of intrinsic neurons contacted by different types of primary afferent fibers (PAF). [. . . ] Our results indicate the existence of a polysynaptic network transferring the information from nociceptive fibers expressing TRPV1 lamina II to the deep laminae (III-V) as a stimulation of excitatory and inhibitory synaptic transmissions. This is the first demonstration of the existence of such functional interactions between laminae II and III-IV. In addition, these results suggest that the increase in inhibitory glycinergic transmission in lamina II and laminae III-IV requires neural relay located in a layer deeper than the lamina IV, probably in lamina V and depends on the establishment of a phenomenon of disinhibition. [. . . ] Taken together, these results contribute to a better understanding of the structure of networks of spinal interneurons involved in the processing of nociceptive information, highlighting the importance of relations between the synaptic layers of the dorsal horn during this process. A better understanding of the structure and operation of these networks will approach the study of functional plasticity phenomena taking place in these networks of interneurons in situations of inflammatory or neuropathic pain

Full textDue to the constant increase of the world demand for wood, the planted forests are in fast expansion notably in tropical countries such as Brazil where plantations of eucalypts, the most productive and spread out planted species, may reach 10 million ha by 2020. The expansion of these plantations on less fertile sites, combined with the context of climate change lead to important issues about (i) the sustainability of these plantations under more frequent and intense drought events and (i) the impact on the environment of these highly productive plantations with very short rotations (6 yr), particularly for nutrient, water and carbon cycles. Eucalypt trees are able to develop very deep root system (<15 m) to reach the water table, and this may play a key role to cope with decreasing soil water availability. However, the role of these deep fine roots in plant nutrition is dramatically under-documented. In this context, the general objective of this study was to evaluate the influence of soil depth combined with water availability on fine root functioning through characterization of the rhizosphere properties. For this purpose, a 5-yr-old clonal Eucalyptus grandis plantation was studied in Brazil in two contrasted water regimes: the +W treatment, receiving normal rainfall was compared with the –W treatment where 37% of the throughfall were excluded in order to mimick the future climate forecasted in the region. Exploratory tests were carried out for the introduction of an innovative lab technology under field conditions: the optodes, which allow mapping rhizosphere pH. The rhizodeposition of eucalypt fine roots interfered with the optical sensor signal and prevented us to get interpretable results. However, some tests on pine trees let us confident of the possibility of using our system for field studies at depth, using some recommendations. Destructive analyses of rhizosphere and bulk soil samples collected along a 4-m deep soil profile showed an effect of depth and rainfall reduction on rhizosphere pH, potassium concentration, rhizodeposition pattern and carbon storage capacity. Concerning nutrition issues, we found an accumulation of potassium and protons within the rhizosphere, especially below 1-m depth (x3.0 and x1.1 for K and H3O+ in +W, respectively) and in reduced rainfall conditions (x7.0 and x1.4 for K and H3O+ in –W, respectively). Repeating these measurements during rainy season confirmed the enrichment of protons and potassium within the rhizosphere, suggesting that these processes may occur all along the year but no treatment effect was observed anymore, pointing to a potential good resilience of the system. The amount of K brought to fine roots by mass flow was estimated to 2.0 kg K ha-1 yr-1 and could not explain the amount of potassium taken up by trees estimated to 17.5 kg K ha-1 yr-1 and the observed accumulation in the rhizosphere. A more likely explanation was the root-induced weathering of K-bearing minerals, partly related to rhizosphere acidification. Proof of ectomycorrhizal association down to 4-m depth further supported the hypothesis of a key role of deep fine roots in plant nutrition. High exchangeable Al3+ concentration was found within the rhizosphere (up to 12.0 mg kg-1). Concerning the carbon storage issue, despite an expected exponential decrease of C and N concentrations within the bulk soil with depth (0.72‰ to 0.12‰ from top soil to 4-m depth), our results showed that more than half of soil C stock within the bulk soil occurred below the first meter. An accumulation of C within the rhizosphere was found, especially at depth (x1.4 below 1 m in +W) and in reduced rainfall conditions (x3.0 at 4-m depth in –W). The same trends were found for N. The rhizosphere effect was conserved during rainy season but not the treatment effect. This work confirmed that deep fine roots play a key role, especially in the context of climate change, for plant nutrition and carbon storage
