García Martín, Elena Salobrar ; Hoyas, Irene ; Leal, Mercedes ; Hoz Montañana, María Rosa de ; Rojas López, María Blanca ; Ramírez Sebastián, Ana Isabel ; Salazar Corral, Juan José ; Yubero Pancorbo, Raquel ; Gil, Pedro ; Triviño Casado, Alberto ; Ramirez Sebastian, Jose Manuel | Hindawi Publising Corp. | 2015-06-08Decreased thickness of the retinal nerve fiber layer (RNFL) may reflect retinal neuronal-ganglion cell death. A decrease in the RNFL has been demonstrated in Alzheimer’s disease (AD) in addition to aging by optical coherence tomography (OCT). Tw[...]texto impreso
In this paper we deal with the problem of axiomatizing the preference relations modeled through Choquet integral with respect to a k-additive capacity, i.e. whose Mobius transform vanishes for subsets of more than k elements. Thus, k-additive ca[...]texto impreso
In this paper we study the relations between divergence measures of two fuzzy sets and other well-known functions, namely aggregation operations and measures of fuzziness. We will show that these functions can be related. Therefore, we study som[...]texto impreso
Non-additive measures are a valuable tool to model many different problems arising in real situations. However, two important difficulties appear in their practical use: the complexity of the measures and their identification from sample data. F[...]texto impreso
In this paper we propose a generalization of the concept of the local property for divergence measures. These new measures will be called g-local divergence measures, and we study some of their properties. Once this family is defined, a characte[...]texto impreso
García Martín, Elena Salobrar ; Rojas López, Blanca ; Ramírez Sebastián, Ana Isabel ; Hoz Montañana, Rosa de ; Salazar Corral, Juan José ; Yubero Pancorbo, Raquel ; Gil, Pedro ; Triviño Casado, Alberto ; Ramirez Sebastian, Jose Manuel | Elsevier / American Academy of Ophthalmology | 2014-03-18Although several postmortem findings in the retina of patients with Alzheimer's disease (AD) are available, new biomarkers for early diagnosis and follow-up of AD are still lacking. It has been postulated that the defects in the retinal nerve fi[...]texto impreso
Fernández, Alberto ; Turrero, Agustín ; Zuluaga Arias, Pilar ; Gil, Pedro ; Maestú, Fernando ; Campo, Pablo ; Ortiz, Tomás | American Medical Association | 2006-03Background: Subjects with mild cognitive impairment (MCI) are at a higher risk of experiencing Alzheimer disease (AD). Magnetoencephalographic temporoparietal dipole densities of low-frequency activity are good predictors of individuals' cogniti[...]texto impreso
García Martín, Elena Salobrar ; Méndez Hernández, Carmen D. ; Hoz Montañana, Rosa de ; Ramírez Sebastián, Ana Isabel ; López Cuenca, Inés ; Fernández Arrabal, José A. ; Rojas Lozano, Pilar ; Wang, Surina ; García Feijoo, Julián ; Gil, Pedro ; Salazar Corral, Juan José ; Ramirez Sebastian, Jose Manuel | MDPI | 2020In Alzheimer’s disease (AD), vascular changes could be caused by amyloid beta (A?) aggregates replacing the contractile smooth musculature of the arteriole walls. These changes happen in the brain vascular network, but also in the eye, and are r[...]texto impreso
In this paper we propose a generalization of the concept of symmetric fuzzy measure based in a decomposition of the universal set in what we have called subsets of indifference. Some properties of these measures are studied, as well as their Cho[...]texto impreso
García Martín, Elena Salobrar ; Ramírez Sebastián, Ana Isabel ; Hoz Montañana, Rosa de ; Rojas, Pilar ; Salazar Corral, Juan José ; Rojas López, Blanca ; Yubero Pancorbo, Raquel ; Gil, Pedro ; Triviño Casado, Alberto ; Ramirez Sebastian, Jose Manuel | Intech | 2016-09-28Over the last few decades, the importance of ophthalmic examination in neurodegenerative diseases of the CNS has reportedly increased. The retina is an extension of the CNS and thus should not be surprising to find abnormal results in both the t[...]
