Full textLes méthodes de modélisation basées sur la structure tridimensionnelle des protéines sont d'une grande utilité dans le développement de médicaments. Cette thèse résume cinq projets de recherche proposant des avancées dans la méthodologie et les protocoles liés à la découverte et à l'optimisation de petites molécules actives. Le premier projet démontre que le paradigme voulant que la surface moléculaire exposée au solvant soit décrite par le contact d'une sonde sphérique de rayon constant de 1.4Å avec la protéine fait apparaître des poches et des cavités hydrophobes irréalistes sur la surface. Une méthode novatrice est présentée où le rayon de la sonde change au contact des différents types d'atome produisant ainsi une représentation plus réaliste des aspérités de la surface ayant pour effet une meilleure définition de la complémentarité de la forme moléculaire ainsi qu'une meilleure estimation de l'énergie électrostatique. Le deuxième projet démontre que l'utilisation d'un simple coefficient d'hydratation pour corriger le calcul de l'énergie libre de liaison entraîne une erreur moyenne importante entre les affinités calculées et mesurées expérimentalement. Conséquemment, une nouvelle fonction d'énergie tenant compte de la solvatation (SIE) a été développée appuyant sa paramétrisation sur des données expérimentales. La fonction SIE est en mesure de reproduire les affinités de 99 complexes ligand-protéine différents avec une erreur moyenne de 1.29 kcal/mol. Dans le troisième projet, la fonction SIE est introduite dans une nouvelle procédure de criblage virtuel (CV). La capacité de la fonction SIE est accrue par l'ajout d'un terme d'entropie et d'un terme décrivant les liaisons hydrogène. La procédure de criblage qui en résulte déclasse la majorité des autres méthodes publiées. Dans le quatrième projet une version modifiée de la procédure de criblage est utilisée pour prédire les modes de

Full textTiivistelmä Entsyymit voivat toimia ylivoimaisina katalyytteinä monissa kemianteollisuuden prosesseissa johtuen niiden hyvästä spesifisyydestä, valikoimiskyvystä, alhaisesta energiantarpeesta ja ympäristöystävällisyydestä. Näistä ominaisuuksista huolimatta entsyymien kaikkien mahdollisuuksien hyödyntämisen esteenä on monia haasteita. Tarvittavia ominaisuuksia ovat katalyyttinen tehokkuus, saatavuus suurina määrinä, alhainen hinta, alhainen tuoteinhibitio sekä korkea aktiivisuus ja stabiilisuus prosessiolosuhteissa. TIM-tynnyrirakenne on yleisin ja monipuolisin proteiinien laskostumisrakenne luonnossa esiintyvissä entsyymeissä. Tässä rakenteessa katalyyttisesti aktiiviset aminohappotähteet ovat sijoittuneet tynnyrirakenteen toiselle puolelle, kun taas stabiilisuuden kannalta tärkeät aminohappotähteet ovat sijoittuneet kokonaan toiselle puolelle. Tämä erityinen rakenne antaa mahdollisuuden muokata proteiinin katalyyttistä aktiivisuutta vaikuttamatta haitallisesti sen stabiilisuuteen. Tämä on täydellinen lähtökohta proteiininmuokkaukselle. Tässä tutkimusprojektissa käytettiin ns. järkiperäistä suunnittelua monomeerisen trioosifosfaatti-isomeraasivariantin (A-TIM) luomisessa. Tämän tutkimustyön pääasialliset tavoitteet olivat (i) uusien sitoutujien löytäminen ja (ii) uuden, suuremman sitoutumistaskun ominaisuuksien määrittäminen röntgenkristallografisilla menetelmillä. Tässä tutkimuksessa havaittiin, että A-TIM kykenee sitomaan yhdisteitä, jotka ovat täysin erilaisia luonnolliseen substraattiin verrattuna. Tässä tutkimuksessa kuvaillaan kolmenlaisia sitoutujia: (i) todelliset villityypin entsyymin substraattianalogit, (ii) substraattianalogit, joihin on liitetty hydrofobinen hiilivetyketju ja (iii) villityypin substraattia suuremmat sokerifosfaatit. Tämän lisäksi A-TIM:n aktiivisen keskuksen todistettiin olevan toimintakykyinen. Yleisellä tasolla tämä tutkimus osoittaa röntgenkristallografisten menetelmien tärkeyden entsyymienmuokkausprojekteissa, joissa entsyymivarianttien ominaisuuksien määritys on tärkeää

Full textStructural health monitoring (SHM) has attracted much attention in many engineering fields like civil, aeronautic, mechanical industry, etc. since it is important to monitor the healthy condition of the operational structure in order to avoid unpredicted structural failure which may have severe consequences. The four-level damage identification process: existence, localization, severity and prediction of damage evolution, can be partly realized if a suitable indicator is chosen. It exists different damage indicators whose application range of frequency spans from vibrational response at low frequencies to the ultrasonic regimes in the mega hertz range.The sandwich structures are widely used in various engineering applications due to its exceptionally high flexural stiffness-to-weight ratio compared to monocoque structures. In this thesis a specified twin-wall sandwich structure in polypropylene was studied and vibration-based indicators were designed by taking use of its relative high damping and propagation directivity characteristics. Numerical investigations on different damage scenarios (i.e., different types of defect and their combinations) and an associated discussion on the range of application were first carried out. Experimental configuration was easily realized with the help of a scanning laser doppler vibrometer (SLDV). Defect was successfully detected by the proposed indicators

Full textDurante la mayor parte de la historia humana, los patógenos han sido una de las principales causas de muertes y enfermedades. Gracias al descubrimiento de los antibióticos hemos conseguido tratar estas enfermedades con facilidad, pero su mal uso ha acelerado la aparición de resistencias a los antimicrobianos (AMRs). Dado que las AMRs han provocado que la mayoría de fármacos antimicrobianos sean ineficaces, el desarrollo de tratamientos alternativos es más necesario que nunca. Los péptidos de la defensa del huésped (HDPs) han sido propuestos como modelos para la generación de nuevos antimicrobianos para luchar contra las infecciones AMR. Sin embargo, la mayoría de HDPs se producen mediante la síntesis química, un proceso que es caro, insostenible y difícil de escalar. Alternativamente, la producción recombinante de HDPs es muy atractiva pero complicada, ya que son péptidos altamente susceptibles de ser degradados y son tóxicos para el huésped recombinante. Sin embargo, los cuerpos de inclusión (IBs), que son agregados de proteína formados durante los procesos de producción recombinante, se pueden utilizar como formato alternativo al de la proteína soluble para permitir la producción de HDPs dentro del huésped sin efectos tóxicos. Por otra parte, la construcción de proteínas quiméricas podría ser una estrategia para expresar péptidos pequeños con éxito. En este contexto, esta tesis explora diversas estrategias para la producción recombinante de HDPs. Por un lado, hemos explorado el uso de las cremalleras de leucina como dominios potenciales para fomentar la producción recombinante de HDPs en la fracción insoluble y para aumentar la calidad de la proteína recombinante en los IBs. Además, hemos desarrollado varias proteínas antimicrobianas multidominio basadas en la fusión de diferentes péptidos HDP y proteínas de la inmunidad innata. Como también hemos utilizado cremalleras de leucina en estos constructos, se pueden expresar de manera efectiva - sin toxicidad para la célula productora. Además, en caso de necesidad, podemos recuperar antimicrobianos solubles a partir de los IBs gracias a un protocolo de solubilización suave y no desnaturalizando. En conjunto, hemos demostrado que estos constructos tienen un amplio espectro de acción antimicrobiana contra bacterias multi resistentes (MDR), tanto en el formato soluble como en el formato de IBs. Es más, los constructos también son capaces de estimular la liberación de IL-8 dentro de un potencial rango de propiedades inmunomoduladoras. Estos resultados nos han invitado a utilizar nuestras proteínas en la biofuncionalizacón de monocapas autoensamblantes para evitar la formación de biofilms, y hemos observado que estas proteínas pueden anclarse a estos materiales y evitar el crecimiento de biofilms. En resumen, estos resultados refuerzan las proteínas antimicrobianas multidominio como potenciales alternativas antimicrobianas con propiedades inmunomoduladoras.
For most of human history, pathogens have been a leading cause of death and illness. Although we have attained the ability to treat them easily, thanks to the discovery of antibiotics, the widespread overuse and misuse of antimicrobial drugs have accelerated the appearance of antimicrobial resistances (AMRs). Because AMRs have rendered most antimicrobial drugs ineffective, the development of alternative approaches is more necessary than ever before. Host defense peptides (HDPs) have been proposed as blueprints for the generation of new antimicrobials to fight AMR infections. Despite this, most HDPs are produced by chemical synthesis, which is expensive, unsustainable, and difficult to scale-up. Alternatively, their recombinant production is very appealing but still challenging. HDPs are highly susceptible to degradation and are generally toxic to the recombinant host. However, inclusion bodies (IBs), which are protein aggregates that usually happen during recombinant production, can be used to allow HDP formation inside the host without being harmful. Also, the construction of chimeric proteins could be a strategy for successful recombinant expression of small peptides. In this context, this dissertation explores several new strategies for the recombinant production of HDPs. We tried leucine zippers as potential domains to drive the recombinant production of HDPs to the insoluble fraction and improve IBs protein quality. After that, we developed several antimicrobial multidomain proteins based on the fusion of different peptides and proteins from innate immunity. Because we also used leucine zippers with these constructs, they could be produced effectively – without toxicity to the microbial cell factory. Moreover, when needed, we were able to recover soluble antimicrobials from IBs using a mild, non-denaturing protocol. Overall, we demonstrated that these constructs have a broad-spectrum antimicrobial action against multi-drug resistant (MDR) bacteria, in both the soluble and IB format, and that they could trigger the release of IL-8 within a range of potential immunomodulatory properties. These outcomes invited us to use our constructs in the biofunctionalization of self-assembled monolayers to avoid biofilm formation. We observed that the chimeric proteins could be anchored to these materials and avoid biofilm growth. In sum, these results reinforce multidomain antimicrobial proteins as potential antimicrobial alternatives with immunomodulatory properties and open up the possibility for many applications of this new generation of antimicrobial protein nanoparticles as well as their soluble analogs.

Full textLos avances recientes en el campo de la microscopía basada en la localización de moléculas únicas ("localization-based microscopy") han permitido visualizar estructuras biológicas y procesos dinámicos dentro de la célula con una resolución espacial sin precedentes. Determinar la organización de estructuras complejas, como la cromatina, bajo condiciones fisiológicas y patológicas es uno de los objetivos más importantes del campo de la biología molecular. En la actualidad, una de las principales limitaciones de esta familia de técnicas experimentales es la dificultad de extenderlas a múltiples colores, de manera que se puedan visualizar simultáneamente múltiples moléculas de interés. En la primera parte de mi doctorado, hemos desarrolado un método que permite la adquisión simultánea de imágenes de microscopía multi-color de súper resolución, basado únicamente en la excitación de fluoróforos, en lugar de en sus propiedades de emisión de fluorescencia. A través de la modulación de la intensidad de los láseres de excitación a diferentes frecuencias, los distintos canales pueden ser identificados en base a la respuesta del fluoróforo. Este método permite reducir el tiempo de adquisición de las imágenes con la técnica "DNA points accumulation in nanoscale topography" (DNA-PAINT), al tiempo que mantiene todas sus ventajas: mínima interferencia entre los distintos canales, mínimo fotoblanqueamiento de los fluoróforos, máximo intensidad de la señal de fluorescencia, capacidad de mantener la densidad de fluoróforos por canal de la imagen y capacidad de utilizar el campo de visión completo de la cámara. Una cuestión biológica pendiente que se beneficiará del desarrollo y aplicación de estas técnicas avanzadas de microscopia es la relación entre la estructura de la cromatina y la actividad genética de una célula. La cromatina es un complejo compuesto por ADN, proteínas e histonas, que ayuda a compactar y organizar el genoma dentro del reducido espacio del núcleo celular. Aplicando microscopía de súper resolución, trabajos previos han demostrado que, dentro de las fibras plegadas de cromatina, los nucleosomas están organizados en grupos heterogéneos llamados "nucleosome clutches". Esto difiere del modelo que aparece en los libros de texto, el cual sugería un plegamiento de los nucleosomas mucho más ordenado y jerárquico. Además, estas observaciones mostraron que los grupos de nucleosomas son más pequeños y menos densos en las células madre embrionarias (ESC) en comparación con las células progenitoras neuronales (NPC), en correlación con el estado de compactación de la cromatina. En este proyecto hemos utilizado modelos computacionales y el método de microscopía avanzada llamado "Single Molecule Tracking" (SMT) para comparar la estructura de fibras sintéticas de cromatina y la dinámica de los nucleosomas, con las imágenes de súper resolución de la fibra de cromatina en el proceso de diferenciacón celular (desde ESCs hasta NPCs). En primer lugar, utilizando un modelo de grano grueso ("coarse-grained model"), hemos generado estructuras de las fibras de cromatina correspondientes a una región de 30kpb alrededor del gen de pluripotencia Oct4. Para ello hemos obtenido las posiciones de los nucleosomas a partir de los datos de MNase-Seq, y la proporción de la histona H1 por nucleosoma y la cantidad de acetilación de la cola de la histonas, a partir de datos experimentales. Las configuraciones de las fibras plegadas resultantes mostraron una mayor compactación total y de los grupos de nucleosomas en las células NPC, en comparación con las ESC, recapitulando los datos de obtenidos de las imágenes de súper resolución. Además, los datos de SMT, tanto en tiempos de exposición de cámara cortos (15ms) como largos (500ms), muestran que la reposición de los nucleosomas en la cromatina y la dinámica local dentro de la fibra se correlacionan con las con las características estructurales observadas en los datos de superresolución y los modelos de polímeros.

Full textIn the next generation of linear particle accelerators, challenging alignment tolerances are required in the positioning of the components focusing, accelerating and detecting the beam over the accelerator length in order to achieve the maximum machine performance. In the case of the Compact Linear Collider (CLIC), accelerating structures, beam position monitors and quadrupole magnets need to be aligned in their support with respect to their reference axes with an accuracy of 10 um. To reach such objective, the PACMAN (Particle Accelerator Components Metrology and Alignment to the Nanometer Scale) project strives for the improvement of the current alignment accuracy by developing new methods and tools, whose feasibility should be validated using the major CLIC components. This Ph.D. thesis concerns the investigation, development and implementation of a new non-destructive intracavity technique, referenced here as 'the perturbative method', to determine the electromagnetic axes of accelerating structures by means of a stretched wire, acting as a reference of alignment. Of particular importance is the experimental validation of the method through the 5.5 mm iris-mean aperture CLIC prototype known as TD24, with complex mechanical features and difficult accessibility, in a dedicated test bench. In the first chapter of this thesis, the alignment techniques in particle accelerators and the novel proposals to be implemented in the future linear colliders are introduced, and a detailed description of the PACMAN project is provided. The feasibility study of the method, carried out with extensive electromagnetic fields simulations, is described in chapter 2, giving as a result, the knowledge of the theoretical accuracy expected in the measurement of the electromagnetic axes and facilitating the development of a measurement algorithm. The conceptual design, manufacturing and calibration of the automated experimental set-up, integrating the solution developed to measure the electromagnetic axes of the TD24, are covered in chapter 3. The future lines of research and developments of the perturbative method are also explored. In chapter 4, the most significant results obtained from an extensive experimental work are presented, analysed and compared with simulations. The proof-of-principle is completed, the measurement algorithm is optimised and the electromagnetic centre is measured in the TD24 with a precision less than 1 um and an estimated error less than 8.5 um. Finally, in chapter 5, the developments undertaken along this research work are summarised, the innovative achievements accomplished within the PACMAN project are listed and its impact is analysed.

En el cas del Colisionador Compacte Lineal (CLIC), accelerant estructures, monitors de posició de fes i imants necessiten ser alineats en el seu suport amb respectar a les seves destrals de referència amb una precisió de 10 um. Per assolir tal objectiu, el PACMAN (Metrologia de Components de l'Accelerador de partícules i Alineament al Nanometer Escala) projecte s'esforça per la millora de l'actual precisió d'alineament per mètodes nous en desenvolupament i eines, la viabilitat dels quals hauria de ser validada utilitzant els components de CLIC importants.

Full textDetta arbete handlar om den produktutveckling som utförts i samarbete med Ericsson –Enclosure & Power och deras utveckling av kabinett för radiobasstationer (RBS). Ericssons expansion på nya marknader ökar mängden krav på deras olika supportsystem. För att kunna vidareutveckla sin verksamhet och samtidigt erbjuda ett stort antal produktlösningar utvecklar de för närvarande en ny modulbaserad produktfamilj. Idag finns ett flertal metoder för produktmodularisering men man saknar erfarenhet av att arbeta med sådana metoder på Ericsson– Enclosure & Power. Detta arbete undersöker vilka metoder som är lämpliga att använda i detta sammanhang, och hur man på bästa sätt ska implementera dem. Objektet för denna studie är Batteribasenheten (BBUn) som är ett fundament för montering av RBS kabinettet med ett utrymme för reservbatterier. Ett övergripande tillvägagångssätt föreslås för att säkerställa att utvecklingen av denna produkt inkluderar en bra modulär uppbyggnad. Delvis består tillvägagångssättet av vanliga produktutvecklingsmetoder såsom Quality Function Deployment (QFD), koncepturval och prototyper. I övrigt består det i modulariseringsmetoderna Function Structure Heuristics och Design Structure Matrix (DSM) som används först på funktionsnivå innan konceptgenereringsfasen och därefter på komponentnivå under detaljutvecklingen av det slutliga konceptet. Detta arbete beskriver hur dessa metoder har implementerats, hur produktenhar utvecklats från idé till prototyp samt den resulterande produktmodulariteten. Den slutliga utformningen utvärderas mot den angivna kravspecificeringen och fördelarna och nackdelarna med att använda en formaliserad metod för produktutveckling på Ericsson – Enclosure & Power diskuteras.

Human head reconstruction becomes an important research topic while the computer graphic technologies developing in past few decades. Because of large amount of the face features are complex, and the needs of the real-time animation of the facial expressions, it is necessary to elaborate the head model. In the past, researchers often selected the features by hands. It is a subjective method. This research uses an objective and automatic method to locate the features on the head. The reconstruction of head model is according to the feature points and lines, and provides different levels of details to fit different requirements. All of these levels of meshes will not lose the features. This article improves the method described in “Feature-based Digital Head Reconstruction.” Systematically and objectively extract features automatically according to the MPEG-4 definition. This research also introduces a method that can rectify the tilt head to enhance the recognition, and a method that can replace the poorly sampled ear data from the body scanner by a better one from the CT image. The extendable feature-based head model can be easily changed the density of the meshes according to the requirement. It is much better suitable for the applications of data transmission across the internet and computer graphics animation.

Currently, Li-ion batteries are the best power source for electric vehicles (EV) because of their outstanding electrochemical performances. Li-ion batteries improve the efficiency of the EVs and increase EV's mileage. The Li-ion batteries own high energy and power densities; however, misusing the batteries sometimes result in disastrous accidents. A battery system required by an EV is usually composed of multiple Li-ion cells connected in series and parallel configuration. Thus, in order to avoid over-charging or over-discharging of any single cell and improve inconsistencies among cells, battery management system is constructed to make sure the battery operating in the safe range. Battery is the core component of an electric vehicle and battery management system is the primary mechanism to balance EV's security and performance. This study develops a set of multi-module battery management system suitable for the 96V32S Li-ion battery packs of the self-developed 96V electric vehicle. The battery management system is composed of the module battery management system and the master control system. The battery management system is developed based on the master-slave structure. 96V32S LiFePO4 batteries are divided into two packs in serials 48V16S. Battery modules are managed by two module battery management systems respectively and the master-control-system receives the module battery data from the module battery management systems. In the master-slave structure of this study, the master-control-system is master, and the two module battery management systems are Slaves. The master-control-system sends corresponding commands to corresponding module battery management systems and module battery management systems answer the requests of master-control-system accordingly. Master-control-system conducts analysis, calculation and alert according to the received data, and then deliver the data to human-machine interface of the vehicle information system, providing for the drivers or researchers to learn the state of the electric vehicle and battery packs, so as to achieve the aims of monitoring and security. The electric vehicle used in the current study is manufactured based on the tricycle structure with two front wheels and one power rear wheel. The body of the used EV is processed and assembled by aluminum materials, and uses the 96V/2500W hub motor as the power source. In addition to the lightweight electric vehicle, the module battery management systems have cell voltage measurement system, current measurement circuit, active balanced system, abnormal warning for module battery and isolated communication function, thus it can manage the 48V16S battery packs separately without master-slave structure. The master-control-system is the coordinator of multi-module battery management systems. The master takes charge of receiving the parameters and states of the two module battery management systems, detects the total voltage, total current of the battery and the driving data by its own measuring system, and calculates and controls the residual electricity and 2-phase charging method according to the data. Vehicle information system conducts intelligent instrumentation, data analysis and storage. HMI system written in the vehicle information system includes the virtual meters, cell data, state of battery pack and data storage, thus the drivers or researchers can know the state of the electric vehicle in real time. The battery management system developed in this study can accurately measure the parameters and state of the battery packs, including single cell voltages with accuracy within 20mV, active balance mechanism with maximum balancing current of 6A, and the multi-module battery management system with the master-slave structure, thus it is suitable for applying in the high-serial and multi-module battery systems. In addition, the 2-phase charging method of this study can guarantee each cell in full charge under the condition of no over-charge, accurately estimate the residual electricity of the battery packs according to the residual electricity, and control error to be less than 5%. This study will be installed and tested on the self-developed 96V electric vehicle. The test items include hill climbing, crusing, starting, accelerating. Test drives show and record the real-time data by the installed vehicle information system. After actual test, the battery management system can normally and stably operate in various road conditions with reliability. The 2-phase charging method can increase the covered mileages of the battery systems. It will more accurately estimate the residual electricity of the battery packs by coordinating with the residual electricity estimation, therefore, the drivers can accurately estimate the remaining runtime to avoid error state of charge estimation.
