Alda, Javier ; Rico García, José María ; Salgado Remacha, Francisco Javier ; Sánchez Brea, Luis Miguel | Elsevier | 2009-06-14We analyze the optical behavior of square Fresnel zones plates. A theoretical analysis and numerical simulations based on the Rayleigh-Sommerfeld approach have been developed analyzing properties such as the depth of focus and the intensity of t[...]texto impreso
The discovery of a dinosaur clutch in Upper Cretaceous tidal flat deposits in the Tremp Formation in Biscarri, Isona (Lleida, Spain), provides insight into the mode of life of some dinosaurs. The clutch occurs in grey marls that were originally [...]texto impreso
Hernando Grande, Antonio ; Garcia, M.A. ; Gálvez Alonso, Fernando ; Guinea, F. | Elsevier | 2020-04-15It is shown that magnetic forces as the force -/+ mu(V) over barB, exerted on electron spins at rest, account for both the transverse spin imbalance typical of spin Hall effect and the transverse charge imbalance associated with pure spin curren[...]texto impreso
The direct correlation function of a Huid of aligned planar hard convex orientable bodies is determined exactly using a simple form for the separation of the centers at contact. An approximate analytical proposal for the direct correlation funct[...]texto impreso
Campano, Cristina ; Miranda, Rubén ; Merayo, Noemí ; Negro, Carlos ; Blanco, Ángeles | Elsevier | 2017-05-17Cellulose nanocrystals (CNC) are high added value products which can be used in many applications. In this research, CNC were directly produced from two recycled papers: old newspapers (ONP) and 100% recycled newsprint (NP). CNC were also obtain[...]texto impreso
Studies assume that socioeconomic status determines individuals’ states of health, but how does health determine socioeconomic status? And how does this association vary depending on contextual differences? To answer this question, our study use[...]texto impreso
Generalist pathogens are capable of infecting a wide range of host species, and may pose serious disease emergence threats if accidentally moved outside their native areas. To date little effort has been devoted to identifying geographic areas t[...]texto impreso
Sequences of discrete Levy and adjoint Levy transformations for multidimensional quadrilateral lattices are studied. After a suitable number of iterations we show how all the relevant geometrical features of the transformed quadrilateral lattice[...]texto impreso
Taenia solium (the pork tapeworm) is present in most developing countries, where it is a frequent cause of seizures and other neurological disease. Parasitic larvae invade the human brain, establish, and eventually resolve, leaving a calcified s[...]texto impreso
This paper complements previous estimations regarding socioeconomic inequalities in obesity for Spanish adults, and provides new evidence about the mechanisms through which socioeconomic status (SES) affects obesity. Microdata from the Spanish N[...]texto impreso

We study several properties of disjointly homogeneous Banach lattices with a special focus on two questions: the self-duality of this class and the existence of disjoint sequences spanning complemented subspaces. Various results around these pro[...]texto impreso
Puell Marín, María Cinta ; Pérez Carrasco, María Jesús ; Hurtado-Ceña, Francisco Javier ; Álvarez-Rementería Fernández, Laureano | Elsevier | 2015-11PURPOSE: To compare disk halo size in response to a glare source in eyes with an aspheric apodized diffractive multifocal intraocular lens (IOL) or aspheric monofocal IOL. SETTING: Rementeria Ophthalmological Clinic, Madrid, Spain. DESIGN: Pro[...]texto impreso
Discrete models of dislocations in cubic crystal lattices having one or two atoms per unit cell are proposed. These models have the standard linear anisotropic elasticity as their continuum limit and their main ingredients are the elastic stiffn[...]texto impreso
Arriaga, Laura R. ; Rodríguez García, Ruddi ; Moleiro, Lara H. ; Prévost, Sylvain ; López-Montero, Iván ; Hellweg, Thomas ; Monroy Muñoz, Francisco | Elsevier | 2017Cholesterol is an intriguing component of fluid lipid membranes: It makes them stiffer but also more fluid. Despite the enormous biological significance of this complex dynamical behavior, which blends aspects of membrane elasticity with viscous[...]
