Texte intégralIn the past few years, optogenetics was used in research to replace electrical stimulation of neurons by photo-stimulation. Scientists now search a way to extend optogenetics to cardiac research. Many were able to control the heartbeat of rodents using light. These experiments were conducted using wired and cumbersome equiments with electrocardiogram (ECG) recording using electrodes and photo-stimulation using optical fibers. These systems increase tests subjects stress which can induce measurements errors. This master's thesis describes the design of a device answering this problem. The developed system enables cardiac photostimulation and ECG recording wirelessly with an implant and a low power electronic circuit. The device also includes a real-time algorithm to reduce motion artifacts shown in preliminary testing. Finally, the operation of the prototype is demonstrated during in-vivo experiments.

Texte intégralNeural data recording has seen huge progress during the past few years; it helps for diagnosing diseases inside the brain like Parkinson disease and clinical depression. A big number of Parkinson’s patients use a neural implant to lessen tumors and rigid movement. A small electrode will be placed on the brain. It helps to control motion and when an electrical simulation happens, it helps reduce and even eliminate Parkinson symptoms. The neural data recording system requires a complete link starting by recording neural data using electrodes, convert this data onto digital data and transmit the digitized data using a wireless link. In this work we are focusing on sending neural data from an implanted device through the skin using light. There are different ways to transmit data wirelessly with either antenna or with an optical transmitter; we discuss about those methods in the literature review chapter. We choose to work with VCSEL or Vertical Cavity Surface Emitting Lasers; a specialized laser diode with improved efficiency and high speed compared to other optical devices. The first part of the research was to study the best way to transmit data through the human skin, the method of transmission and the properties of the medium through which the light will propagate. After choosing the method of transmission, we designed an integrated link using 0.18 um CMOS technology. This integrated link consists of two parts, the transmitter side which is a VCSEL driver able to drive the VCSEL with a 3 dB bandwidth of 1.3 GHz and low power-consumption of 12 mW, and a receiver side that consists of a photodiode connected to a CMOS transimpedance amplifier with high gain (90 dB) and high speed of (250 Mbps). The second part was to build a discrete optical link with commercial low cost components, so we designed two PCBs (Printed Circuit Board) for the transmitter and receiver side, and we designed a mechanical system to align the transmitter and the photodiode. We then tested our optical link, and it demonstrated the capability to transmit data through 3 mm of pork tissue at a bit-rate of 20 Mbps with low power consumption of 3 mW using OOK (On Off Keying) data transmission, and finally we did a comparison between our results and other works.

Texte intégralThe central nervous system is composed of heterogeneous populations of neurons. Studying their functional properties in the intact central nervous system (CNS) is key to be able to understand their respective role in signal processing within entire networks. To achieve this, it is essential to be able to record electrophysiologically from identified neurons in the intact tissue. Recording from identified cells types in vivo has remained a challenge, especially for local circuit neurons. Novel fluorescent labeling techniques open new possibilities on that front. To take full advantage of these recent developments, the ability to record electrophysiological signals from single neurons must be combined with optical detection of individual cells deep into CNS tissue. Here it describe the development of a novel microprobe based on a dual core optical fiber: an optical core that excites locally fluorescent labeled cells and collects back the fluorescence, and an electrolyte filled hollow core that performs classical extracellular single unit electrophysiological measurements. In contrast to previous solutions, this novel design allows production of microprobes with sufficient optical resolution for single cell detection: the microprobes could be pulled down to tips sizes of 6 µm, which is smaller than the cell body diameter of most neuron populations. It is presented the evolution of the microprobe design and the experimental setup. To characterize the optical properties of the probes, it is showed a series of in vitro experiments and numerical simulations. Then, it is presented in vivo experiment to identify and record single spinal neurons labeled retrogradely with fluorescent dyes as well as single GABAergic interneurons expressing GFP in the brain of transgenic mice. It’s also established a spatial criterion to correlate optical and electrophysiological signals, confirming co-detection of single cells. This novel microprobe vastly expands possibilities for in vivo electrophysiological recording by providing parallel access to single cell optical monitoring.

Texte intégralMannoni, Laurent. « L'enregistrement du mouvement au XIXe siècle : les méthodes graphique et chronophotographique ». Paris 3, 2003. http://www.theses.fr/2003PA030079.
Texte intégralThe graphic method consists of recording, by means of a stylus which traces a curve on a revolving cylinder covered with a sheet of paper coated with lamp-black, or on any other suitable surface, the variations of volume, length, pressure or speed of an organ or an object in movement. Instruments for the graphic method were introduced into France from Germany by the physiologist Etienne-Jules Marey, who went on to develop them to a very high degree of sophistication. Marey also conceived and originated chronophotography. In Marey's system of chronophotography, the movements of an organ or an object are no longer inscribed by a stylus attached to a geared lever but by the intermediary of light - that famous " pencil of nature ", in the words of William Henry Fox Talbot. The difference between the graphic and chronophotographic methods essentially lies in the " pencils " which serve to inscribe the movement : one is solid, the other luminous. In the nineteenth century, the graphic and chronophotographic methods made possible the knowledge, evaluation and thus, often, the mastery of innumerable phenomena relating to medicine, physiology, natural sciences, different branches of physics and the arts. The graphic and chronophotograpic methods, not without having suffered some " distortions " (Taylorism, eugenics), have a place in the origin of modern art in its abstract forms and have played a not negligible role in academic art ; they are at the base of modern methods of study of the physiology of movement ; finally, they contributed significantly to the realisation of cinematographic techniques, both silent and sound

Texte intégralThis thesis relates to preliminary studies aiming to achieve quantum memories in rare earth ions doped inorganic crystals. If photons are the best vectors for information transport, materials systems represent the best quantum objects to achieve inforrmation storage and manipulation. As they are insensitive to decoherence by spontaneous emission, Raman transitions are an interesting process to realize the light-matter coupling. Rare earth ions have been chosen because they exhibit relatively long coherence lifetime. After a detailed presentation of the different rare earth ions and the different crystals, we justify the choice of working on Thulium:YAG ions, for which we built a stabilised laser. We discuss on the possibility to create an efficient three-level system in this material with the help of an external magnetic field, using the coupled effect of hyperfine interaction and electronic Zeeman interaction. We present the experimentals results of spectroscopy of Thulium ion in a magnetic field and we measure the system gyromagnetic factors, which present a good agreement with the theoretical values. We present the three-level system preparation procedure, aiming to eliminate the transitions inhomogeneous broadening. We describe a first coherent manipulation process of a thulium ions macroscopic ensemble: the population adiabatic transfer between two levels of the system, using the "Complex Hyperbolic Secant" excitation procedure. Transfer rates of about 95% have been achieved

Texte intégralThe imperial decree of October 15th 1810 established the first national regulation on classifiedfacilities. It laid the ground for French law on the industrial environment by creating the firstnomenclature. An analysis of over 140 nomenclature texts published since then has providedinsight into a certain number of societal developments. Indeed, the nomenclature system has beena powerful social marker for more than two centuries. Furthermore, the effectiveness of the lawhas depended greatly on the nomenclature system. While its original objective was to fosterfreedom of enterprise, it gradually evolved towards a law protecting third parties, in particularregarding property rights. The Act of December 19th 1917 on classified facilities furtherstrengthened this purpose, generally placing the focus first on third parties and then on theenvironment. The act also favored workers’ health and safety, which had been ignored until then.On the other hand, the act abolished the principle of preliminary authorization by introducing adeclaration scheme for the benefit of operators. The Act of July 19th 1976 on classified facilities forenvironmental protection took over and modernized all of these provisions but without reallyintroducing any innovation. The nomenclature system rapidly underwent a series oftransformations that generally resulted in the decommissioning of numerous facilities. Thedeclaration scheme continued to expand. However, the creation of the registration scheme in 2009,which is somewhere between the declaration and authorization schemes, has led to a dramaticreduction in the reach of the latter. The transposition of recent European directives has spurredthis process by introducing a new nomenclature. Never before has such a regression onenvironmental law been reached, especially since it is combined with a marked separation betweenclassified facilities and the receiving environment

Texte intégralUnimodal inputs and outputs in current systems have become very mature with touch applications or distributed services for geo-localization or speech, audio and image recognition. However, the integration and instantiation of all these modalities, lack of an intelligent management of the acquisition and restitution context, based on highly formalized notions reflecting common sense. This requires a more dynamic behavior of the system with a more appropriate approach to manage the user environment.However, the technology required to achieve such a goal is not yet available in a standardized manner, both in terms of the functional description of unimodal services and in terms of their semantic description. This is also the case for multimodal architectures, where the semantic management is produced by each project without a common agreement in the field to ensure inter-operability, and it is often limited to the processing of inputs and outputs or fusion / fission mechanisms. To fill this gap, we propose a semantic service-oriented generic architecture for multimodal systems. This proposal aims to improve the description and the discovery of modality components for assistance services: this is the architecture SOA2m. This architecture is fully focused on multimodality and it is enriched with semantic technologies because we believe that this approach will enhance the autonomous behavior of multimodal applications, provide a robust perception of the user-system exchanges, and help in the control of the semantic integration of the human-computer interaction.As a result, the challenge of discovery is addressed using the tools provided by the field of the semantic web services

Texte intégralSubmarine paleoseismology is a discipline based on the recognition and study of past earthquakes from submarine records such as turbidite deposits. This discipline was initially developed in the 1990’s in the Cascadia region (north-west coast of the USA), and was subsequently, applied to other seas, oceans and lakes. The Ionian Sea is a small, narrow and deep basin located in the central Mediterranean Sea and bounded by two accretionary wedges, the Mediterranean Ridge to the east and the Calabrian wedge to the west. Eastern Sicily and Calabria region have been repeatedly struck by destructive historical earthquakes, sometime followed by tsunamis, such as the 1693 AD earthquake in Catania (magnitude to 7.4) or the 1908 AD earthquake in Messina (magnitude to 7.1).This latter earthquake triggered a submarine landslide and turbidity currents that ruptured submarine cables. In the Ionian abyssal plain, another type of deposit is observed in seismic data, expressed as successive transparent layers. These mega-deposits, several meters in thickness, are associated with large extreme events (earthquakes, volcanic eruptions, tsunamis) and are named megaturbidites or homogenites.The research conducted during this thesis focuses on the interpretation of turbidites and mega-deposits, observed by a new data set located in the western part of the Calabrian prism and acquired during the CIRCEE cruise, in October 2013. The understanding of the sources and the origin of these deposits is essential for the interpretation of paleoseismological record in the region. The general objective is to improve our understanding of the chronology and origin of major catastrophic events that have affected the region. These new data, include piston cores, bathymetry and seismic profiles (Chirp and HR), and allow us, for first time, to revisit the interpretation of sedimentary processes and origin of mega deposits and in particular the most recent deposit named "Augias deposit" This deposit, whose thickness reaches 12 meters in Ionian abyssal plain, can be linked to the 365 AD Crete earthquake and associated tsunami. Based on the sedimentological description and different measurements that were conducted, three type facies could be identified ("megaturbidite", "homogenite" and "thick sandy turbidite") that are the expressions of different sedimentary processes.The second part of this thesis represents a paleoseismological study of the last 25 ka in Ionian Sea based on age models. The time period covered by the cores includes the end of the last glacial period, the sea level rise and the historical period. This allowed identification of deposits from the historical period whose main trigger of turbidity currents are earthquakes. On the other hand for earlier deposits, eustatic and climatic variations are shown to have a stong effect on the frequency of turbidites

Texte intégralIon channels are membrane proteins responsible for ion transport across biological membranes. Due to their ubiquity, they are promising drug targets but are not yet fully exploited as such due to experimental restrictions in their study. Electrical measurement of ion channels activity within in vitro artificial lipid bilayers would enable to overcome these restrictions. However, there is not yet a system satisfying all the requirements for ion channels studies: stability and purity of the lipid bilayer, low noise level, fast insertion of ion channels, fluidic integration, ability to perform simultaneous optical characterization. The aim of this phD was to assess in which extent the use of an SOI (Silicon On Insulator) substrate bearing nanopores could satisfy all these requirements. 10 nm to 160 nm diameter nanopores were fabricated in an SOI substrate and characterized. A transparent fluidic cell was used for fluidic addressing. This transparent cell allows combined electrical and optical characterization. Electrical properties of the device in aqueous environment were studied, allowing to bring out improvement prospects. The combined electrical and optical characterization was demonstrated with fluorescent nanoparticle trapping experiments on the nanopores. Finally, promising results about the formation of a free-standing lipid bilayer are presented

Texte intégralIndividuals with schizophrenia have been shown to be impaired in the attribution of mental states to others. We have demonstrated that they were also impaired in the detection of elementary intentional motions such as chasing. This impairment was situated at the perceptual stage of processing, with abnormal ocular behaviour, but also at the cognitive stage. Using an object translocation paradigm, we found that the same group of patients was also impaired in the attribution of goals and believes to others. This impairment was entirely explained by a lower visual attention dedicated to faces. We have developed ocular measures that showed an attraction of the visual attention of control participants by intentional motion on Frith-Happé animations. Finally, we have shown on other control participants that intentional reasoning from comic strips was associated with a greater visual scanning compared to mechanistic reasoning. These last two paradigms could be particularly useful to confirm that individuals with schizophrenia show an abnormal visual attention toward mentalistic information, as demonstrated in the first two paradigms. The results suggest that visual exploration of mentalistic stimuli could benefit from remediation strategies in schizophrenia
