Texte intégralWith the emergence and growth of large databases of information, efficient methods for storage and processing are becoming increasingly important. The existence of a metric distance measure between data entities enables efficient index structures to be applied when storing the data. Unfortunately, this is often not the case. Amino acid substitution matrices, which are used to estimate similarities between proteins, do not yield metric distance measures. Finding efficient methods for converting a non-metric matrix into a metric one is therefore highly desirable. In this work, the problem of finding such conversions is approached by embedding the data contained in the non-metric matrix into a metric space. The embedding is optimized according to a quality measure which takes the original data into account, and a distance matrix is then derived using the metric distance function of the space. More specifically, an evolutionary scheme is proposed for constructing such an embedding. The work shows how a coevolutionary algorithm can be used to find a spatial embedding and a metric distance function which try to preserve as much of the proximity structure of the non-metrix matrix as possible. The evolutionary scheme is compared to three existing embedding algorithms. Some modifications to the existing algorithms are proposed, with the purpose of handling the data in the non-metric matrix more efficiently. At a higher level, the strategy of deriving a metric distance function from a spatial embedding is compared to an existing algorithm which enforces metricity by manipulating the data in the non-metric matrix directly (the triangle fixing algorithm). The methods presented and compared are general in the sense that they can be applied in any case where a non-metric matrix must be converted into a metric one, regardless of how the data in the non-metric matrix was originally derived. The proposed methods are tested empirically on amino acid substitution matrices, and the derived metric matrices are used to search for similarity in a database of proteins. The results show that the embedding approach outperforms the triangle fixing approach when applied to matrices from the PAM family. Moreover, the evolutionary embedding algorithms perform best among the embedding algorithms. In the case of the PAM250 scoring matrix, a metric distance matrix is found which is more sensitive than the mPAM250 matrix presented in a recent paper. Possible advantages of choosing one method over another are shown to be unclear in the case of matrices from the BLOSUM family.

Texte intégralBone substitute more easy to handle are obtained by infiltrating a porous ceramic (alumina, hydroxyapatite-beta tricalcium phosphate or bioglass) with a solution or a nanodispersion based on polycaprolactone. Pores are covered with a layer of polymer and rupture, which is catastrophic for the ceramic, becomes a controlled one in the case of the composite, with a strong increase in energy to break thanks to crack bridging by polymer fibrils. Another kind of composite material, pliable during insertion, is obtained by infiltrating a polyurethane sponge with plaster or a cement based on alpha tricalcium phosphate. After setting, a layer of cement is obtained on the surface of the pores, the Young modulus and the strength at break are increased in compression and rupture of the composite is of controlled type, with a progressive damage of the structure. In-vitro tests showed the cytocompatability of the composite

Texte intégralThe matrix of a substitution is not sufficient to completely determine the dynamics associated with it, even in the simplest cases since there are many words with the same abelianization. In this paper we study the common points of the canonical broken lines associated with two different irreducible Pisot unimodular substitutions σ1 and σ2 having the same incidence matrix. We prove that if σ1 verifies the Pisot conjecture and 0 is an inner point to the Rauzy fractal associated with the substitution σ1 then these common points can be generated with a substitution on an alphabet of so-called balanced pairs, and we obtain in this way the intersection of the interior of two Rauzy fractals

Texte intégralThe main purpose of the present work is to propose a new BaAl2Si2O8 (BAS) composite reinforced with alumina fibers exhibiting similar physical properties but a higher refractoriness than SiO2 / SiO2 composites. The hexagonal crystal form of BAS is the stable one at high temperatures. However, it is metastable below 1590 °C and it is therefore necessary to stabilize it in order to prevent crystalline transformations. The stabilization of the hexagonal form by atomic substitution, including rubidium at 5 atomic % has been chosen. Regarding the matrix BAS composite, the alumina fibers selection has been justified by their low physical and chemical reactivity with this material. Several elaboration methods of the BAS matrix and of the BAS / alumina composite have been investigated. The development by "reactive spark plasma sintering" (R-SPS) brings an important benefit in terms of reduced elaboration time and yield. This saving time thus limits the BAS exposure to high temperatures and the risk of transformation into monoclinic. Nevertheless, the SPS shaping of oxide materials, including the BAS, is confronted with the presence of important thermal gradient within the sample. This is why shaping in a heating mold is currently in progress, as an alternative to the SPS. This system should allow the use the same thermal cycles as for SPS, but with lower thermal gradient

Texte intégralA Engenharia de Tecidos apresenta actualmente soluções comerciais, para o tratamento de lesões provocadas por queimadura com perda total de pele, que não preenchem todos os requisitos para serem denominados de substitutos definitivos de pele. O objectivo deste trabalho consistiu no desenvolvimento e caracterização físico-química e biológica da componente dérmica de um substituto de pele baseada numa matriz de nanofibras, obtida através da técnica de electrofiação. Os polímeros escolhidos foram a gelatina (GEL), o quitosano (CS) e a policaprolactona (PCL), usando como solvente comum o ácido acético. Estes foram depositados individualmente e em mistura, resultando em três tipos de matrizes: unitárias, binárias e ternária. No sistema de matrizes unitárias apenas a de PCL é hidrofóbica. Em termos de propriedades mecânicas a de PCL é a mais elástica e dúctil e a de GEL a mais rígida e frágil. Os testes in vitro revelaram adesão e proliferação celular em todas as matrizes. Porém, apenas nas matrizes de PCL e CS foi observada migração de células em profundidade. Nos testes in vivo constatou-se uma boa integração das matrizes de CS e de GEL nas feridas, resultando numa cicatriz re-epitelizada ao final de 4 semanas. No sistema de matrizes binárias e ternária, a de PCL/GEL é a menos hidrofílica. Relativamente às propriedades mecânicas observou-se um domínio da componente CS nas misturas preparadas com este polímero. Já a matriz de PCL/GEL reflecte a mistura de ambos os componentes. Os testes in vitro apresentaram adesão e proliferação celular em todas as matrizes. Foram encontradas evidências de processos de invasão celular em todas as matrizes, excepto na matriz de PCL/GEL. Finalmente, em termos de testes in vivo destacou-se uma boa integração das matrizes de CS/GEL e de CS/PCL/GEL na lesão, resultando numa cicatriz re-epitelizada ao final de 4 semanas.
