Full textThis thesis investigates the pivotal role of emerging non-volatile memory (NVM) technologies, with a primary focus on Resistive Random-Access Memory (ReRAM), in addressing the challenges of memory latency associated with the shrinking of logic components. The exploration begins by elucidating the fundamental physics of ReRAM and its potential applications in in-memory and neuromorphic computing.The second chapter delves into material engineering strategies to optimize ReRAM performance, covering aspects such as top electrode materials, doping effects, and the benefits of a bi-layer resistive switching (RS) oxide stack. These insights provide a foundation for subsequent investigations into device reliability.A Kinetic Monte Carlo (KMC) simulation framework is introduced in the third chapter, offering a powerful tool for probing the microscopic dynamic behavior of ReRAM. This framework becomes instrumental in the fourth chapter, where the physics of ReRAM reliability, specifically resistance fluctuations, is explored in depth. The analysis reveals intricate mechanisms governing fluctuations and their impact on metrics like the standard Failing Bit Count (FBC).In the final chapter, the application of ReRAM devices as synapses in artificial neural networks (ANNs) is revisited. Programming techniques and strategies to mitigate the impact of fluctuations, particularly in multi-level cell (MLC) ReRAM, are discussed. The thesis concludes by emphasizing the crucial role of ReRAM material stack engineering in designing reliable synapses for future computing paradigms.This comprehensive exploration contributes to advancing our understanding of ReRAM's potential, offering insights into device optimization, reliability, and its application in neuromorphic computing. Looking forward, the research underscores the significance of continued innovation in ReRAM material engineering to unlock its full capabilities and facilitate its integration into the evolving landscape of computing technologies
Mortessagne, Pierre. "Characterization of the different populations of granular neurons in the dentate gyrus of the hippocampus : from morphology to function." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0402.
Full textIn the dentate gyrus (DG) of the hippocampus, the generation of dentate granule neurons(DGNs) starts during late embryogenesis, peaks around birth and continues at low levels during adulthood. This continuous neurogenesis makes the DG a unique structure, composed of DGNs from distinct temporal origins, which form subpopulations potentially bearing unique anatomical characteristics and functional roles in hippocampal physiology. Surprisingly, this hypothesis has received limited attention. In this context, our research aimed to elucidate the morphological, electrophysiological, and behavioral characteristics of DGNs subpopulations based on their temporal origin. Building on prior findings from our team that high lighted dendritic differences between these populations, we focused on examining the features of their axons, called mossy fibers (MFs). Using sparse labeling strategies — electroporation to targetembryonically-born (E14.5) and neonatally-born (P0) DGNs, and retroviral injections foradolescent-born (P21) and adult-born (P84) DGNs — we uncovered that DGNs generated laterin life develop larger MF boutons with more filopodia, and exhibit a shorter axon initialsegment. Additionally, using the Osteocalcin-Cre and Ascl1CreERT2 mouse lines to selectivelylabel large cohorts of embryonically-born and adult-born DGNs, respectively, we found thatearlier-born neurons project further onto the CA2 compared to later-born neurons. Following these morphological findings, we further investigated the functional characteristics of temporally distinct DGNs at both the electrophysiological and behavioral levels. The electrophysiological studies revealed similar intrinsic properties between neonatally- and adult born DGNs, and higher basal transmission in neonatally-born DGNs, potentially reflecting alarger number of active sites. Finally, we examined the role of embryonic-born DGNs in socialbehavior, and showed that acute inhibition of these neurons delayed the expression of social preference. However, these functional data remain preliminary and need further investigation.Altogether, this PhD work highlights the significant impact of the birthdate of DGNs on their anatomical and potentially functional characteristics, and emphasizes the importance of considering their precise temporal origin in any structural or functional analysis of the DG

Full textDNA duplication in S phase starts from thousands of initiation sites called DNA replication origins. These replication origins are set in G1 as pre-replication complexes (pre-RC) and fired in S phase following a spatio-temporal program of activation. This program determines which origins will be fired and when. Indeed, all the origins are not fired in the same time and we can distinguish early, middle and late replication origins. This temporal regulation is called "replication timing" and is determined at the "timing decision point" (TDP) in early G1. It's a robust program, which participates to the definition of cell identity, in term of differentiation state or cell type. However, the precise molecular mechanisms involved are poorly understood. Defective timing program has been evidenced in pathological contexts, in particular in cancers, but the mechanisms of this deregulation remain unclear. In the first part of my PhD, I contributed to the discovery of a new regulator of the origin timing program: the specialized DNA polymerase Theta (Pol Theta). Pol Theta is loaded onto chromatin in early G1, coimmunoprecipitates with pre-RC components and modulates the recruitment of Mcm helicases at TDP. Moreover, depletion or overexpression of Pol Theta modifies the timing of replication at a fraction of chromosomal domains. The second part of my work aimed at exploring the mechanisms that regulates replication timing after a replicative stress. I identified a totally new transgenerational adaptive mechanism of DNA replication timing regulation: the modification of the timing of origin activation at chromosomal domains that have suffered from a replicative stress during the previous cell cycle. Daughter cells from a cell that has experienced replication stress at particular domains (late replicating domains, AT rich so they can form structured DNA, and poor in origin density) shows advanced origin activation within these regions. This new biological process in response to replicative stress could be of particular interest in the context of cancer since, tumor cells are characterized by high level of intrinsic chronic replicative stress. This new mechanism may favor cancer cell survival despite replication stress, particularly upon treatments with anti-tumor agents that target DNA

Full textThe microbiological quality of bathing water is progressively decreasing from year to year, and can constitute a major public health problem. Thus, sanitary monitoring of the microbiological quality of bathing waters is carried out in accordance with the European directive (2006/7/EC) to ensure the sanitary safety of bathers and preserve the image of these recreational ecosystems. For many years, the bay of Aytré (Charente Maritime, France), has been classified as "poor quality" and this beach is prohibited for bathing since 2018. The health issues and the preponderant role of this beach on the tourism development and the local economy led to investigate the origin and the spatiotemporal determinism of this fecal contamination. This thesis presents an integrated approach to the analysis of the fecal contamination of Aytré Bay through a multidisciplinary study of different hypotheses analysed since the beginning of the 2000s by the local authorities. The level of fecal contamination of the bathing water during a year was relatively low with a notable seasonal variation in the abundance of the fecal contamination indicators Escherichia coli and enterococci. Exceedances of the regulatory thresholds on 24% and 32% of the water samples from Platin Nord and Platin Sud, the two bathing sites in Aytré Bay, were mainly due to enterococci. The microbiological quality of the sediment over time showed that the sediment was not a diffuse source of contamination in the water. The combined analysis of protein, genetic and chemical markers revealed the presence of enterococci species of environmental origin on the one hand, and on the other hand, a contamination of mainly animal origin and a small contribution from human origin. The analytical strategy and tools developed during this study will help to improve the sanitary surveillance methods of bathing waters

Full textThe reservoir quality is one of the "risk" factors for hydrocarbon exploration or for the future development of geothermal energy in siliciclastic hydrosystems. Reservoir properties are defined by porosity and permeability values. In deep buried siliciclastic reservoirs, chlorite coatings around quartz grains help to preserve these properties. The mechanisms behind these coatings are still poorly understood. The objectives of this study are: (1) to characterize (mineralogy, crystallography, textural and microstructural properties) and to determine the spatial and temporal distribution of clay and clay coatings in well constrained sedimentary environments and within a well-defined stratigraphic framework; (2) to better understand the factors controlling the formation of clay coatings in siliciclastic reservoirs; (3) to describe the intermediate processes of authigenic chlorite formation via different precursor minerals during burial; (4) to predict the distribution of good reservoir properties in relation to clay coatings. The modern analogue chosen for this study is the Gironde estuary, where the presence of detrital clay grain coats was detected in the intertidal zone of tidal and point bars, but also in pluri-meters long sedimentary cores. The formation mechanisms of these coatings have been investigated with the interaction between hydrodynamic and biological processes. Analogies with buried sandstone reservoirs (>3500m) showed that sand facies of external tidal bars deposited at the end of a transgressive cycle are the preferred targets for finding good reservoir properties in estuarine reservoirs. The evolution of detrital clay grain coats during burial was approached by studying buried reservoirs between 400 and 1000m deep. The detrital coatings are transformed into berthierine and mixed-layer chlorite-smectite at depths between 600 and 900m and temperatures between 30-40°C. These minerals are true precursors to ferrous chlorite coatings that appear at greater depth
