Constrained tensor models - Applications to MIMO wireless communication systems
No full textConférence invitéeNational audienceAu cours de la dernière décennie, les modèles tensoriels du type CP, appelés aussi décompositions PARAFAC, ont fait l’objet de très nombreuses applications en traitement du signal et de l’image. Depuis les travaux de pionnier de Sidiropoulos, Giannakis et Bro, en 2000 [1], les communications numériques constituent un domaine d’application privilégié des outils tensoriels. Cet exposé a pour objectif de montrer comment la conception de différents systèmes de communication MIMO a abouti au développement de nouveaux modèles tensoriels avec contraintes. Dans une première partie, différents modèles tensoriels seront présentés de façon unifiée, i.e. les modèles de types Tucker, PARALIND/CONFAC et PARATUCK [2]. Puis, dans une deuxième partie, nous décrirons quatre exemples de systèmes MIMO conduisant à de nouveaux modèles tensoriels contraints pour les tenseurs de signaux reçus: Systèmes CDMA/TST avec codage spatio/temporel tensoriel et allocation de ressources [3]; Systèmes OFDM/STF avec codage/étalement spatio/temporel/fréquentiel et allocation de ressources [4]; Systèmes NL-CDMA avec codage non linéaire [5]; Systèmes coopératifs avec antennes relais et codage spatio/temporel à la source [6].Nous montrerons comment ces modèles tensoriels permettent d’estimer de façon conjointe et semi-aveugle les symboles transmis et les canaux de communication. Des résultats de simulations seront présentés pour illustrer les performances de ces systèmes de communication.[1] SIDIROPOULOS N., GIANNAKIS G., BRO R.

Total plasma carotenoids and mortality in the elderly: results of the Epidemiology of Vascular Ageing (EVA) study
No full textCarotenoids are pigments found in fruits and vegetables. While high intakes of fruits and vegetables have been found to be associated with lower mortality, our objective is to investigate if total plasma carotenoids, via their antioxidant properties. are associated with mortality risk in a free-living elderly population. The 'Epidemiology of Vascular Ageing' (EVA) study (n 1389 59-71 years) is a 9-year longitudinal study with six waves of follow-up. The association between baseline total plasma carotenoids and mortality was determined by Cox proportional hazards regression analyses. Low total plasma carotenoid level was significantly associated with all-cause mortality in men but not in women. After controlling for potential confounding factors, mortality risk increased significantly in men (P=0.03) with plasma carotenoids in the lowest quintile compared with men with plasma carotenoids in the highest (relative risk 2.94 (95 % CI 1.21, 7.17)). A significant association between mortality by cancer and low plasma carotenoid level variable was also found in men (unit = 1 mu mol/l; relative risk 1.72 (95 % CI 1.02, 2.86); P=0.01). Associations between total plasma carotenoids and mortality risk remained statistically significant after taking into account: (1) plasma Se level, which previously was found associated with mortality in this population and (2) thiobarbituric acid-reactive substances level considered as an indicator of oxidative stress. By showing, prospectively, in a general healthy elderly population, that total plasma carotenoid levels were independently associated with mortality risk in men, the present study suggests that total plasma carotenoid levels could be a health indicator in elderly populations
Tensor Coding For Cdma-mimo Wireless Communication Systems
No full textIn this paper, we propose a tridimensional tensor coding for multiple-inputmultiple-output (MIMO) communication systems. This coding allows spreading and multiplexing the transmitted symbols in both space and time domains, owing the use of two allocation matrices. Assuming flat Rayleigh fading channels, the signals received by K receive antennas during P time blocks, composed of N symbol periods each, with J chips per symbol, forma fourth-order tensor that satisfies a new constrained tensor model. A two-step alternating least squares (ALS) algorithm is proposed for blindly and jointly estimating the channel and the transmitted symbols. The performance of the proposed blind receiver is evaluated by means of computer simulations. © EURASIP, 2011.101105De Almeida, A.L.F., Favier, G., Mota, J.C.M., A constrained factor decomposition with application to mimo antenna systems (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2429-2442De Almeida, A.L.F., Favier, G., Mota, J.C.M., Constrained tensor modeling approach to blind multipleantenna cdma schemes (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2417-2428De Almeida, A.L.F., Favier, G., Mota, J.C.M., Multiuser mimo system using block space-time spreading and tensor modeling (2008) Signal Processing, 88 (10), pp. 2388-2402De Almeida, A.L.F., Favier, G., Mota, J.C.M., Space-time spreading-multiplexing for mimo wireless communication systems using the paratuck-2 tensor model (2009) Signal Processing, 89 (11), pp. 2103-2116De Baynast, A., De Lathauwer, L., Aazhang, B., Blind parafac receivers for multiple access-multiple antenna systems (2003) Proc.

Polimorfismos do gene HLA-G em pacientes com psoríase
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Biológicas. Programa de Pós-Graduação em Biologia Celular e do Desenvolvimento.A psoríase é uma doença inflamatória crônica, de etiologia desconhecida, que afeta a pele e as articulações. Nessa doença, assim como em outras doenças inflamatórias, tem sido observada a indução da expressão do gene HLA-G e a molécula produzida é sugerida como um possível mecanismo de proteção tecidual às respostas imunes pró-inflamatórias. O HLA-G possui na sua 3#UTR oito sítios polimórficos descritos: um polimorfismo de presença ou ausência de um fragmento de 14pb (14pb InDel) e sete SNPs (+3003 T/C, +3010 C/G, +3027 A/C, +3035 C/T, +3142 G/C, +3187 A/G e +3196 G/C). A partir disso, o objetivo deste estudo foi genotipar os polimorfismos da 3#UTR, em 100 pacientes e 100 controles (pareados por idade e gênero) e verificar a influência desses polimorfismos na patogênese da doença. Para isso, foi realizado um levantamento de dados epidemiológicos relacionados ao desenvolvimento e gravidade da doença (presença de sintomas de artrite psoriásica, história familial para a psoríase e idade de manifestação dos primeiros sintomas da doença) e estes foram testados como fatores de risco. O DNA foi extraído de sangue total e a genotipagem feita por PCR e visualizada em PAGE 7% corado com nitrato de prata, no qual o polimorfismo de 14pb foi identificado, e por sequenciamento os outros sete SNPs. Do total de pacientes, 57 eram mulheres, 44 indivíduos apresentaram casos na família, 43 manifestaram a doença antes dos 30 anos e 16 manifestaram artrite psoriásica. Foram realizados cálculos das frequências alélicas e genotípicas, análises de associações e a inferência de haplótipos. Após as análises foram encontradas associações, para pacientes que apresentam sintomas de artrite psoriásica, com o alelo *Del (OR=2,929; p=0,019) e o genótipo *DelDel (OR=4,398; p=0015) do polimorfismo de 14pb, assim como o genótipo +3142*CC (OR=6,02; p=0,015) e para aqueles que apresentaram sintomas antes dos 30 anos de idade o genótipo +3003*CT (OR=0,046; p=0,013). Em conclusão, os polimorfismos da 3#UTR do HLA-G são associados à doença bem como aos dados epidemiológicos considerados neste trabalh
