Résumé :
Terahertz (THz) spectroscopy has been proven as an effective detection means for the label-free and nondestructive sensing of biochemical molecules based on their unique roto-vibrational transitions. However, the conventional THz spectroscopic system is unsuitable for minute material sensing due to its far-field detection scheme, low sample amount, and lack of spectral characteristics, leading to low absorption cross-sections and sensitivity. In this study, a 3D plasmonic structure based on a metal-coated woven-wire mesh (MCWM) was experimentally and numerically demonstrated for sensing trace amounts of analytes combined with THz spectroscopy. Dual sharp spectral features were exhibited in the transmission spectrum, originating from the resonant excitation of THz surface electromagnetic modes via the aperture and periodicity of the MCWM unit cell. According to the finite element simulation, an enhanced and localized surface field was formed at THz resonant frequencies and was concentrated at the metal gaps near the periodic corrugations of the MCWM, resulting in enormous resonant dip shifts caused by the tiny variations in membrane thicknesses and refractive indices. Different types and quantities of analytes, including hydrophilic biopolymer (PAA) membrane, nonuniformly distributed microparticles to mimic macro-biomolecules or cells, and electrolyte salts of PBS, were successfully identified by the MCWM sensor with the best thickness and refractive index sensitivities approaching 8.26 GHz/μm and 547 GHz/RIU, respectively. The demonstrated detection limit of thickness and molecular concentration could respectively achieve nanometer and femtomolar scales in PAA macromolecular detection, surpassing the available metallic mesh devices. The MCWM-based sensing platform presents a rapid, inexpensive, and simple analysis method, potentially paving the way for a new generation of label-free microanalysis sensors.

Résumé :
Multi-Carrier Waveform (MCW) modeling and design are envisioned as one of the most important and challenging for the 6th generation (6G) communication networks. In oppose to Orthogonal Frequency Division Multiplexing (OFDM) waveforms, new and innovative design techniques for MCWs have been designed and proposed in recent literature because of their performance superiority. The typical OFDM waveforms have dominated the previous generation of communication systems and proven their potential in many real-time communication environments, but it may not be sufficient to meet the ambitious target of 6G communication systems. Hence, need for new solutions like flexible MCWs and relevant technological advancements in waveform design are needed. This paper proposes designing and evaluating a new MCW design to meet the 6G requirements for spectral efficiency, throughput, and overall system capacity. On the transmitter side, the MCW design proposed in this article employs power domain multiplexing, such as Non-Orthogonal Multiple Access (NOMA), and phase-rotations of the input signal to the Universal Filtered Multi-Carriers (UFMC) modulations, where the Base-Station (BS) assigns different power levels to each user while using the same frequency resources. MATLAB® simulations were performed to assess the proposed MCW performance. Detailed simulation data are employed for comparative performance analysis of the proposed MCW. The results have shown the superior performance of the proposed MCW approach compared to the conventional 5th generation (5G) NOMA-UFMC waveform.

Résumé :
The next generation communication network (NGCN) is expected to provide higher spectral efficiency, low latency, large throughput and massive machine-to-machine type communications. In this regard, the design of the multi-carrier waveform (MCW) is posing a major research problem for the NGCN. To overcome the stated problem, a lot of state-of-the-art work exists that proposes various MCW alternative to the standard orthogonal frequency division multiplexing (OFDM) waveform. It is true that OFDM was used in a number of real-time communication systems of fourth generation (4G) networks. However, their use in the upcoming fifth generation (5G) network is not very feasible. This is because of the strict requirements of 5G communication systems, which also extend beyond 5G systems; hence rendering the use of OFDM infeasible for newer communication standards. To satisfy the requirements of upcoming communication networks, there is a dire need for MCWs with better flexibility. In this regard, a precoding-based MCW has been proposed. The proposed MCW fulfills the requirements of the NGCN in terms of low peak-to-average power ratio (PAPR), high spectral efficiency and throughput. The MCW proposed in this work uses power-domain multiplexing such as non-orthogonal multiple access (NOMA) and phase rotation by using the selective mapping (SLM) and generalized chirp-like (GCL) precoding of the input signal to the universal filtered multi-carriers (UFMC) modulations. Statistical analysis of the PAPR is presented by using the complementary cumulative distribution function (CCDF). The MATLAB® simulations have been carried out to implement the CCDF of PAPR and results show that a PAPR gain of 5.4 dB is obtained when the proposed waveform is compared with the standard NOMA-UFMC waveform at clip rate of 10−3, using 4-QAM.

Résumé :
Background: The provision of home-based care for frail older adults in Italy and Israel is predominately provided by live-in migrant care workers (MCWs). However, despite the important role that they play in filling the demand for home care, MCWs often experience labor rights violations. This not only impacts the well-being of MCWs but also leads to lower-quality care being provided to people in need of support. Method: This scoping review used Arksey and O’Malley’s methodological framework to map literature. This article aims to analyze the scope, main topics, themes and gaps in the existing academic literature on how micro and macro level indicators impact the working and living conditions of live-in MCWs in Italy and Israel. Scopus, Pubmed, and Web of Science Core Collection were searched for peer-reviewed articles. Search terms were adapted from the Multilevel Framework of Transnational Care Migration (MFTCM). Themes were developed using Braun and Clarke’s method for conducting reflexive thematic analysis. Articles were included if they focused on Italy and/or Israel, included analysis on the working and living conditions of live-in MCWs at the macro and/or micro levels, were written in English, and were published between 2015 and 2020. Results: Out of the 1088 articles retrieved, 33 met the inclusion criteria. A total of 18 articles focused on Italy and 14 on Israel, and one focused on both Italy and Israel. The majority of articles in Italy (84 per cent) and Israel (53 per cent) included analysis on care regimes. Only 37 per cent of articles in Italy and 20 per cent in Israel included analysis on gender regimes. At the micro level, 80 per cent of articles in Israel discussed Power/Class Asymmetry, compared to 37 per cent in Italy. In total, six themes were developed. At the macro level, these themes included funding care work, MCWs as a pragmatic approach, care in the home, and valuing care work. At the micro level, the themes included being part of the family, and perceptions on class asymmetries. The findings presented in this review show that MCWs in both Italy and Israel face many of the same challenges in accessing decent work opportunities, despite contrasting employment and migration policies in each country. This can be partially attributed to the undervaluing of care work because of racialized and gendered notions of care. At the macro level, this has contributed to a lack of political will to develop long-term sustainable solutions to create or monitor decent work standards for MCWs. At the micro level, this has led to power imbalances between MCWs and people in need of care and their family members, resulting in MCWs being expected to work hours beyond those contractually allowed, having little to no time off, and experiencing emotional, physical, and sexual abuse. Conclusion: This study provides a review of the most recent contributions to the fields of labor migration and health concerning the MCW markets in Italy and Israel. While there have been many studies in each country that detail the labor rights violations experienced by MCWs, this is the first review that develops themes around the underlying causes of these violations. By thematically analyzing the findings of recent studies and current gaps in existing knowledge, this scoping review assists in building the groundwork for the development and implementation of policy, strategies, practice and research to improve the rights and migration experiences of MCWs.

Résumé :
The effects of incubating monocalcium phosphate monohydrate (MCPM) with liquid hog manure (LHM) on P availability and uptake by Italian ryegrass (Lolium multiflorum Lam.) were evaluated in a 99-d growth chamber experiment. Liquid hog manure with (0.738 g P kg−1 fresh LHM) or without MCPM was aerated for a 21-d period at 24 °C. The soils used in this experiment were an Ormstown silty clay loam (Orthic Humic Podzol), and a Ste. Rosalie clay loam (Humic Podzol). Five treatments were applied to each soil: (i) control with no LHM or MCPM additions, (ii) MCPM, (iii) LHM incubated without MCPM, (iv) LHM incubated with MCPM, and (v) the separate applications of MCPM and LHM incubated without MCPM. Rates of MCPM and LHM applications were 513 kg P2O5 ha−1 and 32 t ha−1, respectively. Incubating LHM with MCPM resulted in a loss of 6% of the total manure-N during the 3-wk incubation period, compared with a 67% loss from the unamended LHM. Additions of both MCPM and LHM had the same effect on shoot-P contents and soil P fractions regardless of whether the materials had been incubated together or added to the soil separately. When compared with adding MCPM only, LHM-MCPM mixtures resulted in greater ryegrass shoot-P contents for plants growing on the Ste. Rosalie soil. However, this increase was approximately equal to the response to LHM additions, and thus presumably not due to improved MCPM P availability. Additions of both LHM and MCPM did not affect soil inorganic P forms compared with the lone addition of MCPM, but sodium hydroxide extractable organic P and sodium bicarbonate extractable organic P tended to be higher when just MCPM was added.

Résumé :
Melanoma cell adhesion molecule (MCAM, CD146, MUC18) is a heavily glycosylated transmembrane protein and a marker of melanoma metastasis. It is expressed in advanced primary melanoma and metastasis but rarely in benign naevi or normal melanocytes. More and more evidence has shown that activation of the MCAM on cell surface plays a vital role in melanoma progression and metastasis. However, the natural MCAM binding ligand that initiates MCAM activation in melanoma so far remains elusive. This study revealed that galectin-3, a galactoside-binding protein that is commonly overexpressed in many cancers including melanoma, is naturally associated with MCAM on the surface of both skin and uveal melanoma cells. Binding of galectin-3 to MCAM, via O-linked glycans on the MCAM, induces MCAM dimerization and clustering on cell surface and subsequent activation of downstream AKT signalling. This leads to the increases of a number of important steps in melanoma progression of cell proliferation, adhesion, migration, and invasion. Thus, galectin-3 is a natural binding ligand of MCAM in melanoma, and their interaction activates MCAM and promotes MCAM-mediated melanoma progression. Targeting the galectin-3–MCAM interaction may potentially be a useful therapeutic strategy for melanoma treatment.

Résumé :
Autologous bone marrow cell (BMC) transplantation has been shown as a potential approach to treat various ischemic diseases. However, under many conditions BMC dysfunction has been reported, leading to poor cell engraftment and a failure of tissue revascularization. We have previously shown that skeletal muscle angiogenesis induced by electrical stimulation (ES) is impaired in the SS/Mcwi rats and that this effect is related to a dysregulation of the renin angiotensin system (RAS) that is normalized by the replacement of chromosome 13 derived from the Brown Norway rat (SS-13BN/Mcwi consomic rats). The present study explored bone marrow-derived endothelial cell (BM-EC) function in the SS/Mcwi rat and its impact on skeletal muscle angiogenesis induced by ES. SS/Mcwi rats were randomized to receive BMC from: SS/Mcwi; SS-13BN/Mcwi; SS/Mcwi rats infused with saline or ANG II (3 ng·kg−1·min−1). BMC were injected in the stimulated tibialis anterior muscle of SS/Mcwi rats. Vessel density was evaluated in unstimulated and stimulated muscles after 7 days of ES. BMC isolated from SS/Mcwi or SS/Mcwi rats infused with saline failed to restore angiogenesis induced by ES. However, BMC isolated from SS-13BN/Mcwi and SS/Mcwi rats infused with ANG II effectively restored the angiogenesis response in the SS/Mcwi recipient. Furthermore, ANG II infusion increased the capacity of BM-EC to induce endothelial cell tube formation in vitro and slightly increased VEGF protein expression. This study suggests that dysregulation of the RAS in the SS/Mcwi rat contributes to impaired BM-EC function and could impact the angiogenic therapeutic potential of BMC.

Résumé :
The SS-16BN/Mcwi consomic rat was produced by the introgression of chromosome 16 from the Brown Norway (BN/NHsdMcwi) rat onto the genetic background of the Dahl salt-sensitive (SS/Mcwi) rat by marker-assisted breeding. We have previously shown that the normotensive SS-16BN/Mcwi consomic strain is better protected from developing left ventricular dysfunction and fibrosis with aging than the hypertensive SS/Mcwi parental strain; however, the mechanism of this protection was not clear since the SS-16BN/Mcwi had both lowered blood pressure and an altered genetic background compared with SS/Mcwi. Microarray analysis of SS-16BN/Mcwi and SS/Mcwi left ventricle tissue and subsequent protein pathway analysis were used to identify alterations in gene expression in signaling pathways involved with the observed cardioprotection on the SS background. The SS-16BN/Mcwi rats exhibited much higher mRNA levels of expression of transcription factor JunD, a gene found on chromosome 16. Additionally, high levels of differential gene expression were found in pathways involved with angiogenesis, oxidative stress, and growth factor signaling. We tested the physiological relevance of these pathways by experimentally determining the responsiveness of neonatal cardiomyocytes to factors from identified pathways and found that cells isolated from SS-16BN/Mcwi rats had a greater growth response to epidermal growth factor and endothelin-1 than those from parental SS/Mcwi. We also demonstrate that the SS-16BN/Mcwi is better protected from developing fibrosis with surgically elevated afterload than other normotensive strains, indicating that gene-gene interactions resulting from BN chromosomal substitution confer specific cardioprotection. When combined with our previous findings, these data suggest that that SS-16BN/Mcwi may have an increased angiogenic potential and better protection from oxidative stress than the parental SS/Mcwi strain. Additionally, the early transient idiopathic left ventricular hypertrophy in the SS-16BN/Mcwi may be related to altered myocyte sensitivity to growth factors.

Résumé :
Retention of nitrogen in manure to be used for crop production and to reduce environmental pollution is an essential management component. The effects of monocalcium phosphate monohydrate (MCPM) and aeration on N retention in liquid hog (Sus scrofa domesticus) manure (LHM) were investigated under laboratory conditions. The manure received 0, 20 or 40 g of MCPM kg−1 of LHM (0, 250 or 500 g MCPM kg−1 manure solids) and was incubated over a 15-d period with and without aeration. Manure pH decreased with added MCPM and then remained constant, but pH increased with time when MCPM was not added. Losses of NH3 from hog manure were significantly reduced by added MCPM, but increased significantly with aeration where MCPM was not added to the manure. The NH4-N content of LHM was higher where MCPM was added to the manure. Conversely, the NH4-N content tended to decrease with aeration in the absence of MCPM. Total N content of LHM was significantly decreased where MCPM was not added to the manure. Aeration had no significant effect on total N. It was concluded that addition of MCPM can increase the NH4-N content of LHM by decreasing NH3-N losses through acidification of the manure. Key words: Aeration, Ca(H2PO4)2∙H2O, hog manure, pH reduction, NH3 loss

Résumé :
L’approccio Bayesiano alle tecniche di machine-learning consente di integrare in un modello le informazioni a priori per evitare problemi di overfitting, cercando di approssimare la distribuzione a posteriori. Fornisce inoltre una metodologia coerente per la scelta fra diversi modelli alternativi, e richiede tipicamente uno sforzo computazionale considerevole, tale da rendere alcuni problemi intrattabili. Questa tesi propone una famiglia di metodologie di tipo Variational Bayes per approssimare la complessità computazionale dell’approccio Bayesiano tramite l’utilizzo di variabili latenti, minimizzando la distanza di Kullback-Leibler tra la distribuzione a posteriori esatta e quella approssimata. Il primo capitolo riepiloga i concetti chiave dell’inferenza bayesiana e gli algoritmi di propagazione. Il secondo capitolo introduce il metodo Variational Bayes, il quale generalizza gli algoritmi di Expectation Maximization (EM) per la stima dei parametri tramite un approccio a massima verosimiglianza. Vengono inoltre discusse le approssimazioni fattorizzate per i metodi di Expectation Propagation (EP). Nei capitoli da 3 a 5 vengono derivate e testate diverse varianti dei metodi Variational Bayes per la famiglia dei Cluster Weighted Models (CWMs) e, partendo da un breve cenno storico, vengono proposte diverse nuove classi di CWM. Inizialmente viene analizzato il problema della riduzione di dimensionalità nei CWM, introducendo una nuova classe basata su t-distributed stochastic neighbor embedding (tSNE). Nel secondo lavoro viene proposto un Multinomial CWM per la classificazione multinomiale ed un Zero-inflated Poisson CWM per dati di tipo zero-inflazionato. Vengono derivati ed applicati gli algoritmi EM per la stima dei parametri, considerando tre diverse alternative per il passo di massimizzazione: Minimi Quadrati Ordinari (OLS), Minimi Quadrati Pesati Iterati (IRLS), e Discesa Stocastica del Gradiente (SGD). Per concludere, vengono testate le performance classificative dei modelli CWM utilizzando otto criteri diversi e vari Adjusted Rand Index (ARI). Nel sesto capitolo vengono proposte due varianti del metodo di Expectation Propagation per inverse models denominate EP-MCMC e EP-ADMM, applicandole a modelli bayesiani per image-reconstruction e confrontandone le performance con i metodi MCMC. Il settimo capitolo chiude la tesi, traendo le conclusioni dei lavori svolti e riassumendo i possibili sviluppi futuri.<br>The Bayesian framework for machine learning allows the incorporation of prior knowledge into the system in a coherent manner which avoids overfitting problems but rather seeks to approximate the exact posterior and provides a principled basis for the selection of model among alternative models. Unfortunately, the computation required in Bayesian framework is usually intractable. This thesis provides a family of Variational Bayesian (VB) framework which approximates these intractable computations with latent variables by minimizing the Kullback-Leibler divergence between the exact posterior and the approximate distribution. Chapter 1 presents background materials on Bayesian inference, and propagation algorithms. Chapter 2 discusses the family of variational Bayesian theory. It generalizes the expectation maximization (EM) algorithm for learning maximum likelihood parameters. Finally, it discusses factorized approximation of Expectation propagation. Chapter 3 - 5 derive and apply the variants of Variational Bayesian to the family of cluster weighted models (CWMs). It investigates the background history of CWM and proposes new different members into the family. First, the dimensionality of CWM is explored by introducing the t-distributed stochastic neighbor embedding (tSNE) for dimensionality reduction which leads to CMWs based on tSNE for high-dimensional data. Afterwards, we propose a Multinomial CWM for multiclass classification and Zero-inflated Poisson CWM for zero-inflated data. This work derives and applies the Expectation Maximization algorithm with three different maximization step algorithms: Ordinary Least Squares (OLS), Iteratively Reweighted Least Squares (IRLS), and Stochastic Gradient Descent (SGD) to estimate the models' parameters. It finally examines the classification performance of the family of CWM by eight different information criteria and varieties of Adjusted Rand Index (ARI). Chapter 6 proposes a variant of Expectation Propagation: EP-MCMC, EP-ADMM algorithms to the inverse models. It demonstrates EP-MCMC and EP-ADMM on complex Bayesian models for image reconstruction and compares the performance to MCMC. Chapter 7 concludes with a discussion and possible future directions for optimization algorithms.

Résumé :
Discovery of mesoporous materials by Mobil researchers in 1992 opened a new field in catalytic applications. The materials designated as M41S family are MCM-41 with one-dimensional hexagonal structure, MCM-48 with three-dimensional cubic structure and MCM-51 with unstable lamellar structure. This family of materials have high surface areas up to 1500 m2/g, narrow pore size distributions with pore sizes varying from 20 to 100 &Aring<br>. These materials can be activated by incorporation of metals or active compounds into their structures. In this study, copper and nickel incorporated MCM-41 type catalytic materials were synthesized via different methods namely, impregnation, high temperature and low temperature direct synthesis methods. The Cu-MCM-41, and Ni-MCM-41, as well as synthesized MCM-41 were characterized by using XRD, TEM, N2 sorption, SEM, XRF, EDS, AAS and TPR. MCM-41 was synthesized with high temperature direct synthesis method. High surface area values up to 1400 m2/g of MCM-41 mesoporous materials were obtained with high pore volumes up to 1.17 cc/g. Cu-MCM-41 type catalytic materials were synthesized with three different methods. Impregnation and high temperature direct synthesis methods gave better results than those of low temperature direct synthesis method. In impregnation, relatively high surface area values (730 m2/g) were obtained with Cu/Si mole ratio as high as 0.3 in the product. For the case of high temperature direct synthesis products, Cu/Si mole ratios as high as 0.26 were obtained with somewhat smaller surface areas (400 m2/g). Low temperature direct synthesis method is the least favorable method in metal loading. Ni-MCM-41 type of catalytic materials were synthesized by impregnation and high temperature direct syntheses methods. Ni incorporation by high temperature direct synthesis method gave high surface area values (560-930 m2/g) having Ni/Si mole ratios of 0.12-0.28.

Nesta pesquisa foram sintetizadas as seguintes estruturas porosas: Inicialmente foi obtido o percussor lamelar MCM22-(P) com razão molar SiO2\Al2O3 = 30 e ativada para obter sua forma zeólítica MCM-22 a 550 0C por 5 horas. Em seguida, foi realizada a síntese do material micro-mesoporoso do tipo MCM-22/MCM-41, tratando 2 g da zeólita MCM-22, com uma solução de 25 mL de brometo de cetiltrimetilamônio (CTABr) a 10 % em massa, onde o material permaneceu em estufa a 1100C por 7 dias. Com o intuito de obter um novo material com melhor organização estrutural, utilizou-se a MCM-22 nas seguintes proporções (5%, 10% e 15%), permanecendo em estufa a 300C por 24 horas, sendo ativado em corrente de ar por 5500C por 5 horas. Os resultados das caracterizações de difratometria de raios-X, evidenciaram a formação do precursor MCM-22 (P) e sua forma zeólítica MCM22, com os picos da topologia MWW. A curvas obtidas por meio da análise termogravimétrica (TG/DrTG), demostraram as perdas de massa da água e demais adsorvatos. As micrografias (MEV), apresentou formato toroidal com depreciamento na região central para a MCM-22. Por meio dos resultados de adsorção física de N2, verifica-se que as zeólitas MCM-22, com isotermas do tipo I e loop de histerese do tipo H4. A partir dos difratogramas de raios - X para os materiais micro-mesoporosos foi possível observar a formação das estruturas porosas, com a identificação dos picos de reflexão pertinentes a fase microporosa da MCM-22 e da peneira molecular MCM-41, coexistindo em uma única fase estrutural. As imagens obtidas por MEV, detectam a formação de aglomerados de partículas da fase mesoporosa sendo constituída em torno da fase microporosa. A análise textural mostraram uma diminuição do volume de microporos e um aumento do volume de mesoporos, com isotermas do tipo IV e histereses 2. Demonstrando assim que as caracterizações foram eficazes na elucidação das estruturas porosas. Foi possível obter os materiais micromesoporosos para ambas as metodologias adotadas, sendo o teor de 5% de zeólita MCM-22 a melhor condição de síntese para obtenção desse novo material.<br>The research on the development of micro-mesoporous structures has the purpose of obtaining porous materials with superior characteristics, once it seeks to join the high acidity of MCM-22 zeolite with the mesoporous system of MCM41 molecular sieve, consequently improving the diffusion of bulky molecules. In this research, the following porous structures were synthesized: Initially, the MCM-22-(P) lamellar precursor was obtained with molar ratio of SiO2\Al2O3 = 30 and was activated to obtain its MCM-22 zeolite form at 550 °C for 5 hours. Then, MCM-22/MCM-41 micro-mesoporous material was synthesized by treating 2 g of MCM-22 zeolite with a solution of 25 mL of 10% wt cetyltrimethylammonium bromide (CTABr), where the material remained in an incubator at 110 °C for 7 days. In order to obtain a new material with better structural organization, the MCM-22 was used in the following proportions (5%, 10% and 15%), remaining in an incubator at 30 °C for 24 hours, being activated in air stream at 550 °C for 5 hours. The results of the X-ray diffraction characterization demonstrated the MCM-22 (P) precursor formation and its MCM-22 zeolite form, with MWW topology peaks. The curves obtained by means of the thermogravimetric analysis (TG/DrTG), showed the losses of water mass and other adsorbates. The micrographs (SEM) presented toroidal format with depreciation in the central region for MCM-22. By means of the results of physical adsorption of N2, it was verified for MCM-22 zeolites: type I isotherms and hysteresis loops of type-IV. From the X-ray diffractograms for the micro-mesoporous materials, it was possible to observe the formation of the porous structures, with the identification of the reflection peaks pertinent to the microporous phase of MCM-22 and the MCM-41 molecular sieve, coexisting in a single structural phase. The SEM images detected the formation of particle agglomerates of the mesoporous phase being constituted around the microporous phase. The textural analysis showed a decrease in the volume of micropores and an increase in the volume of mesopores, with type IV isotherms and hysteresis loops of type-II. Thus demonstrating that the characterizations were effective in elucidating the porous structures. It was possible to obtain the micro-mesoporous materials for both methodologies, being the 5% content of MCM-22 zeolite the best synthesis condition to obtain this new material.

Résumé :
[Truncated abstract] Melanoma cell adhesion molecule (MCAM) is highly expressed in more than 70% of metastatic melanoma and is correlated with invasive potential. However, the specific contribution MCAM makes to invasion and metastasis in melanoma is not clear. In this study, I have demonstrated that transfection of MCAM into MCAM-negative melanoma and CHO cells leads to changes in cell shape, and the modulation of cell-to-cell and cell-matrix interactions. MCAM positive cells were slower to spread on collagen type I, collagen type IV and laminin 1 than MCAM negative cells, although these differences were not apparent on vitronectin, fibronectin and laminin 10. In contrast, MCAM expression had little effect on cell adhesion to any of the matrices tested. MCAM positive (compared to negative) cells also showed morphological changes and a rearrangement of the actin cytoskeleton when plated on a matrix containing laminin 5. Taken together, these data suggest that MCAM expression modulates β1-integrinmediated spreading on matrix, but has little effect on αvβ3-mediated cell-matrix interactions. As this study provided little evidence to suggest that MCAM transfection altered β1 integrin expression levels on melanoma cells, it is proposed that a competitive interaction between the cytoplasmic domains of MCAM and β1 integrin may affect mature focal adhesion assembly. MCAM expression in melanoma cells was also associated with decreased cell movement over matrix into a scratch-wound site and an increased tendency to form cell cords on Matrigel. These two assays gauge the propensity of a cell to engage in cell-cell versus cell-matrix interactions, and suggest that MCAM positive cells favour cell-cell adhesion. Interestingly, MCAM transfection was also associated with an increased ability of melanoma cells to migrate through a basement membrane towards a chemoattractant. ... Analysis of the intracellular domain of MCAM revealed the presence of tyrosine and dileucine endocytosis signals. Interestingly, disruption of these two motifs did not seem to impair the internalization of MCAM from the cell surface. The di-leucine motif, however, was necessary for the recycling of MCAM back to the surface following endocytosis. Lastly, MCAM was found to exists as dimers within the cell membrane in the absence of ligand, although the exact location of the dimerization motif is not yet clearly defined. Collectively, findings from my study suggest: MCAM expression in melanoma cells facilitates cell-cell interactions, whilst concomitantly modulating cell-matrix interactions. MCAM transfection also leads to enhanced migration of melanoma cells through a basement membrane. Thus, MCAM expression may increase the ability of melanoma cells to migrate as a collective, a feature of highly invasive cancer. The intracellular domain of MCAM interacts with ApxL2, a novel member of the Shroom family of actin-binding proteins. It is likely that ApxL2 links a proportion of MCAM within the cell to the actin cytoskeleton, contributing to cell shape determination and other processes, such as migration. MCAM exists as dimers on the cell surface and is internalized at least partially by a clathrin-mediated mechanism.

Résumé :
Tutkielmassa tutkitaan suurimman uskottavuuden menetelmään perustuvaa Expected Maximization-algoritmia (EM-algoritmi). Työn pääpaino on algoritmin ominaisuuksien teoreettisessa tarkastelussa eikä siinä käsitellä todellisia tutkimusongelmia tai empiirisiä aineistoja. Aluksi tarkastellaan algoritmia matemaattisesti SU-menetelmän tavoin. Tämä teoriaosuus perustuu pääsääntöisesti McLachlanin ja Krishnanin kirjaan The EM Algorithm and Extensions (1997). Algoritmin avulla tutkitaan kahden normaalijakauman sekoitusta ja tähän liittyviä parametreja. Tämä esimerkki perustuu pääsääntöisesti Louisin (1982) artikkeliin. EM-algoritmin lisäksi tutkitaan Monte Carlo EM-algoritmia (MCEM-algoritmi). Algoritmia sovelletaan yksinkertaisen yleistetyn lineaarisen sekamallin parametrien analysoinnissa. Aineistona käytetään McCullochin artikkelin esimerkin mukaan simuloitua binääristä dataa. Tässä osuudessa lähteinä on pääsääntöisesti käytetty McCullochin artikkelia Maximum likelihood algorithms for generalized linear mixed models (1997) ja Robertin ja Casellan kirjaa Introducing Monte Carlo Methods with R (2010). Lopuksi vertaillaan muodostetulla MCEM-algoritmilla laskettuja estimaatteja toiseen Markovin ketju Monte Carlo-menetelmään. Tätä varten simuloitua aineistoa analysoidaan myös bayesiläisittäin soveltamalla Gibbsin otantaa parametrien posteriorien simuloimisessa. Pääasiallisena lähteenä on käytety Läärän kirjoittamaa luentomonistetta Johdatus bayesiläiseen tilastotieteeseen (2013). EM-algoritmilla saatiin normaalijakaumien sekoituksessa erittäin hyviä SU-estimaatteja. Algoritmi on herkkä alkuarvojen valinnalle ja kaukana SU-estimaateista valituilla alkuarvoilla algoritmia on ajettava kauan uskottavuuden maksimoimiseksi. MCEM-algoritmin tapauksessa Monte Carlo otoskoon valitseminen liian suureksi lähinnä hidastaa algoritmia kohtuuttomasti eikä millään tavalla edistä algoritmin stabiloitumista. Tutkielmassa ei saatu MCEM-algoritmilla estimaatteja, jotka olisivat maksimoineet uskottavuusfunktion arvon. Laskemalla aineistosta bootsrap-estimaatit saatiin paremmat tulokset, joilla uskottavuusfunktion arvo on MCEM-estimaatteja suurempi.

Résumé :
The minichromosome maintenance (MCM) proteins are essential for the initiation and progression of DNA replication. MCMs are believed to function as the replicative helicase in archaea and eukaryotes. In the present studies, human MCM and archaeal MCM from Methanococcus maripaludis were purified from E.coli and assembled as complexes. The six MCMs from human eo-purified over multiples steps including three chromatographic steps when eo-expressed in E. coli suggesting that they form a heterohexamer complex. Reconstitution of in vitro helicase activity of the human complex and individual subunits of M maripaludis were described. Furthermore the effect of phosphorylation on human MCM complex and M maripaludis MCM A were also tested and the effect of phosphorylation was shown to be inhibitory on helicase activities. Different reaction conditions were monitored on MCM helicase activity and the most interesting was the effect of salts on helicase assays which showed that glutamate has a significant positive effect while chloride ions inhibit helicase activity. Putative kinases were purified from M maripaludis and Methanocaldococcus jannaschii and trials were conducted to assign them a role in regulating the DNA initiation process.

Résumé :
Abstract Multi-Criteria Decision Methods (MCDM) as a complement to current practices for identifying an initial compromise solution to the problem of wind turbine micro-siting are proposed. MCDM deals with multiple objectives in decision-making. The main goal of these methods is to choose among several alternatives using decision criteria previously defined. The use of MCDM guarantees the identification of the alternative that better performs than all the others according to the selected criteria. After a literature review on available methods for micro-siting of offshore wind turbines in a specific location, and an introduction to the MCDM, the usefulness and potential of MCDM in siting floating wind turbines is highlighted. The MCDM methods can add new parameters to the floating wind farms’ layout process. The results of this study support the potential role of these methods as crucial tools to technology developers and decision-makers.

Résumé :
MCM-41 consists of a hexagonal array of long, unconnected cylindrical pores with diameters that can be tailored within the range 1.6–10nm. As a porous silica nano-material, MCM-41 is thought to have a special thermal conductivity and is a promising porous substrate for mesoporous composites with high or low thermal conductivity. The Equilibrium Molecular Dynamics numerical simulations of thermal conductivity of MCM-41 are performed in this paper. FB potential equation and procedure of annealing are employed to get the structure of MCM-41. The Green-Kubo method is used to calculate the thermal conductivity of MCM-41. At the same time, the kinetic method is used to predict the thermal conductivity of MCM-41 for comparison. It turns out that the shell thermal conductivities of MCM-41 distribute within a reasonable range and increases linearly as porosity decreases, approaching the thermal conductivity of aerogels.

Résumé :
Multi-Criteria Decision Making (MCDM) aims at modelling expert preferences and assisting decision makers in identifying options best accommodating expert criteria. An instance of MCDM model, the Choquet integral is widely used in real-world applications, due to its ability to capture interactions between criteria while retaining interpretability. Aimed at a better scalability and modularity, hierarchical Choquet integrals involve intermediate aggregations of the interacting criteria, at the cost of a more complex elicitation. The paper presents a machine learning-based approach for the automatic identification of hierarchical MCDM models, composed of 2-additive Choquet integral aggregators and of marginal utility functions on the raw features from data reflecting expert preferences. The proposed NEUR-HCI framework relies on a specific neural architecture, enforcing by design the Choquet model constraints and supporting its end-to-end training. The empirical validation of NEUR-HCI on real-world and artificial benchmarks demonstrates the merits of the approach compared to state-of-art baselines.

Résumé :
Abstract The composite of organophosphorus groups loaded on MCM-41(MCM-Zr-TBP) was prepared by multi-steps impregnation method to develop a novel adsorbent for radioactive lanthanides extraction from the secondary contaminated water. The synthesized hybrid material was characterized by SEM and TG. Dy(III) was taken as the representative of trivalent lanthanides. The adsorption performance of Dy(III) on MCM-Zr-TBP composite was systematically studied as the functions of solution pH, initial concentration, interaction time and aqueous temperature. The results showed that Dy(III) adsorption on MCM-Zr-TBP composite was highly dependent on aqueous pH and initial metal ion concentration. Compared with the Freundlich and pseudo-first order models, the Langmuir and pseudo-second order models presented better fitting for the adsorption data. These results indicated that MCM-Zr-TBP was found to be an effective and competent adsorbent, which could be used for the effective removal of lanthanides from the wastewater.

Résumé :
An effective method for performing the thermal optimization of stationary and rotating MCM disks with an unconfined round-jet impingement under space limitation constraint has been successfully developed. The design variables of stationary and rotating MCM disks with an unconfined round-jet impingement include: the ratio of jet separation distance to nozzle diameter (H/d), steady-state Grashof number (Grs), jet Reynolds number (Rej), rotational Reynolds number (Rer). The total experimental cases for stationary and rotating MCM disks are statistically designed by the Central Composite Design (CCD) method. In addition, a sensitivity analysis, the so-called ANOVA, for the design factors has been performed. In the stationary MCM disk with an unconfined round-jet impingement, the contribution percentage of jet Reynolds number on the thermal performance is 95.86%. The effect of jet Reynolds numbers on chip temperature distribution is more significant than that of the H/d ratio and steady-state Grashof number. In rotating MCM disk with an unconfined round-jet impingement, the effect of jet Reynolds number, which has the contribution percentage of 91.81%, dominates the thermal performance. Furthermore, the comparisons between the predictions by using the quadratic Response Surface Methodology (RSM) and the experimental data are made. The maximum deviations for transient stagnation Nusselt number and transient average Nusselt number for the cases of stationary MCM disk are 10.05% and 11.82%, respectively; and 9.41% and 12.44% for the cases of rotating MCM disk, respectively. Finally, with the Sequential Quadratic Programming (SQP) technique, a series of thermal optimal designs under space limitation constraint H/d≤12 has been efficiently performed. Comparisons between the numerical optimization results and the experimental data are made with a satisfactory agreement.
