Marín, Aguilar Susana. "Local structure and dynamics of dense colloidal systems : from patchy particles to hard spheres." Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPASP052.
Повний текст джерелаThe role played by the structure in determining the dynamics of glassy colloidal systems is still a subject of debate. However, there is compelling evidence of a direct link between changes in the local structure and the dynamical slowdown in glassy systems. Here, we explore the interplay between local structure and dynamics by using patchy particles as glass formers. This is done by making use of molecular dynamics simulations. We show that reinforcing icosahedral geometry causes, the system to exhibit an extreme slowdown in its dynamics. With these results, we provide a route for controlling glassy dynamics through the use of patchy particles. Additionally, an interesting point is whether we can extract information about dynamics from only structural information. In order to explore this point, we simulate a wide variety of hard-sphere mixtures. We show that global dynamics of these systems can be precisely predicted by quantifying the tetrahedrality of the local structure: an order parameter that consists of counting the number of tetrahedra each particle participates in. The predictions of this order parameter maintain their accuracy over a wide variety of densities proving its universality in this family of glass formers. Moreover, it is also capable of capturing the changes in the local dynamics, as regions with high tetrahedrality are strongly correlated with regions with slow dynamics. Finally, we demonstrate that unsupervised machine learning techniques can be used to classify particles with different structural environments, which are strongly correlated to local dynamics

O principal objetivo deste estudo foi avaliar a integridade mecânica após fadiga de coroas de silicato de lítio reforçadas com zircônia cimentadas e conectadas a sistemas de implantes do tipo cone Morse. Quarenta implantes de titânio foram inseridos em bases de poliacetal simulando osso de suporte. Os pilares protéticos correspondentes foram conectados aos implantes usando um torque de 20 N.cm controlado por um torquímetro digital portátil. Estruturas protéticas unitárias foram projetadas por computador para produzir coroas vitrocerâmicas de dissilicato de lítio (LD) ou silicato de lítio e zircônio (LZS) por termo- pressão. Após cimentação e conexão das coroas, os grupos implante-pilar-coroa foram submetidos a testes de fadiga (n = 10) sob uma carga de 200 N em 500.000 ciclos a 5 Hz imersos em solução eletrolítica a 37 °C. Depois dos ensaios de fadiga, as coroas de cada grupo foram removidas para avaliar valores de torque de remoção do pilar protético ao implante (n = 7). Os grupos de coroa-implante-pilar restantes foram seccionadas transversalmente em 90° em relação ao plano da conexão pilar-implante para a inspeção de fraturas e microgaps por microscopia eletrônica de varredura. Grupos controle foram imersos na solução eletrolítica mas não foram submetidos aos testes de fadiga. Após imersão em solução e sem efeito de fadiga, os valores de torque de remoção dos pilares para os grupos LD e LZS estavam em 18,014 ± 1,634 N.cm e 18,214 ± 0,813 N.cm, respectivamente. No entanto, os valores de torque de remoção diminuíram significativamente em ambos os grupos, registrando valores de 12,8 ± 1,6 N.cm e 14,9 ± 1,08 N.cm, para o grupo LD e o grupo LZS, respectivamente (p <0,05). Não houve diferença significativa nos valores de torque de remoção entre os dois grupos não submetidos à fadiga assim como entre os dois grupos teste (após fadiga). A análise microscópica revelou que o tamanho dos microgaps (0,9 ± 0,3 µm) encontrado em conexões implante-pilar aumentou significativamente (4,2 ± 0,9 µm) para os grupos submetidos a testes de fadiga (p<0,05). Além disso, foram detectadas micro-trincas nas interfaces entre coroa-adesivo e adesivo-pilar em ambos os sistemas após testes de fadiga. As coroas vitrocerâmicas à base de silicato de zircônio e lítio cimentadas e aparafusadas aos implantes dentários resistiram aos testes de fadiga simulando um período de seis meses de mastigação. No entanto, os resultados confirmaram uma diminuição do torque nos pilares com o aumento dos microgaps das conexões pilar-implante e a presença de micro-trincas nas interfaces coroa-adesivo como consequência do estímulo mecânico dinâmico.
Abstract : The main aim of this study was to assess the mechanical integrity of zirconium- lithium silicate crowns cement- and screw- retained to a Morse taper titanium implant-abutment system after fatigue. Forty titanium implants were placed in poliacetal to mimic bone support. Abutments were torqued to the implants on 20 N.cm using a digital handheld torque meter. Each implant-abutment received a unit maxillary premolar crown that was computer-designed and hot-pressed. Crowns were divided into two groups: A) lithium disilicate (LD); or B) zirconium-lithium silicate glass-ceramic (LZS). Implant-abutment-crown groups were submitted to mechanical cycling tests (n = 10) on 200 N at 5 Hz for 500,000 cycles in a Ringer?s electrolytic solution (37 °C). After fatigue tests, crowns from each group were removed to evaluate removal torque values on abutment to implant. The remaining crown-implant-abutment assemblies were cross-sectioned at 90° to the implant-abutment joint for inspection of cracks and the microgap by scanning electron microscopy. After immersion in Ringer's solutions, removal torque values without effect of fatigue recorded for LD group were at 18.0 ± 1.6 N.cm while values at 18.2 ± 0.8 N.cm were recorded for LZS group. However, removal torque values after fatigue tests significantly decreased down to 12.8 ± 1.6 N.cm for LD while LZS group revealed values at 14.9 ± 1.1 N.cm for LZS (p < 0.05). There was no significant difference in torque values between the test groups after fatigue. Microscopic analyses revealed that the microgap size found at implant-abutment connections at about 0.9 ± 0.3 µm significantly increased up to 4.2 ± 0.9 µm for the groups subjected to fatigue tests. Also, cracks at the crown-adhesive or at adhesive-abutment interfaces were detected at both systems after fatigue tests. Zirconium-lithium silicate glass-ceramic crowns cement- and screw-retained to dental implants were mechanically successful under fatigue testing in an electrolyte solution. However, the findings confirmed a loosening of mechanical integrity of the crown-adhesive-abutment interfaces as well as decrease in removal torque values on abutment to implant joints after fatigue.

Повний текст джерелаDatasets come in a variety of forms and from a broad range of different applications. Typically, the observed data is noisy or in some other way subject to randomness. The recent developments in machine learning have revived the need for exact theoretical limits of probabilistic methods that recover information from noisy data. In this thesis we are concerned with the following two questions: what is the asymptotically best achievable performance? And how can this performance be achieved, i.e., what is the optimal algorithmic strategy? The answer depends on the properties of the data. The problems in this thesis can all be represented as probabilistic graphical models. The generative process of the data determines the structure of the underlying graphical model. The structures considered here are either sparse random graphs or dense (fully connected) models. The above questions can be studied in a probabilistic framework, which leads to an average (or typical) case answer. Such a probabilistic formulation is natural to statistical physics and leads to a formal analogy with problems in disordered systems. In turn, this permits to harvest the methods developed in the study of disordered systems, to attack constraint satisfaction and statistical inference problems. The formal analogy can be exploited as follows. The optimal performance analysis is directly related to the structure of the extrema of the macroscopic free energy. The algorithmic aspects follow from the minimization of the microscopic free energy (that is, the Bethe free energy in this work) which is closely related to message passing algorithms. This thesis is divided into four contributions. First, a statistical physics investigation of the circular coloring problem is carried out that reveals several distinct features. Second, new rigorous upper bounds on the size of minimal contagious sets in random graphs, with bounded maximum degree, are obtained. Third, the phase diagram of the dense Dawid-Skene model is derived by mapping the problem onto low-rank matrix factorization. The associated approximate message passing algorithm is evaluated on real-world data. Finally, the Bayes optimal denoising mean square error is derived for a restricted class of extensive rank matrix estimation problems
