Martínez Matos, Óscar ; Torchia, Gustavo Adrián ; Lencina, Alberto Germán ; Tocho, Jorge Omar | Springer-Verlag | 2008-05Volume grating formation by spatially-selective defect bleaching is demonstrated in coloured KCl:CO_3K_2 crystals. The sample is coloured by a train of pulses with a wavelength of ?=?266 nm and bleached with a cw Ar-laser with a wavelength of ?=[...]texto impreso
Cano Sevilla, Francisco Jose ; Lázaro, L. ; Luna, G. ; Marin, E. ; Martín, J. ; Rio del, A. ; Santesmases , J. G. ; Yurramendi, Y. | Springer-Verlag | 1988This paper shows the steps we have taken in order to define and design a first prototype of an expert system aimed at the general practitioner. The first part is devoted to analyze the systemic approach we gave to the definition problem. Also ar[...]texto impreso
Minuesa Asensio, Álvaro ; Barrio Asensio, María del Carmen ; González Gómez, Ignacio ; Murillo González, Jorge Alfonso | Springer-Verlag | 2016-07The different approaches used in arthroscopic stabilisation of the acromioclavicular joint are well known. However, and despite a great incidence of ectopic pectoralis minor insertion, an alternative choice for the use of arthroscopic portal has[...]texto impreso
In this note we prove that the uniformity of a complete metric space X is characterized by the vector lattice structure of the set U(X) of all uniformly continuous real functions on X.texto impreso
Villarino, Guillermo ; Gómez, Daniel ; Rodríguez, Juan Tinguaro ; Montero, Javier | Springer-Verlag | 2018Most supervised classification algorithms produce a soft score (either a probability, a fuzzy degree, a possibility, a cost, etc.) assessing the strength of the association between items and classes. After that, each item is assigned to the clas[...]texto impreso
Llanes Estrada, Felipe José ; Cotanch, Stephen R. ; Szczepaniak, Adam P. ; Swanson, Eric S. | Springer-Verlag | 2004-03We review theoretical calculations for the pseudoscalar vector meson hyperfine splitting with no open flavor and also report a many body field theoretical effort to assess the impact of chiral symmetry in the choice of effective potentials for r[...]texto impreso
Symmetry exists in nature and art. The rotational symmetry of a simple daisy must have at one time or another stirred geometric thoughts in the least mathematical mind. On a higher scale, the florets of Helianthus maximus naturally arrange thems[...]texto impreso
We show how to enlarge the covariance groups of a wide variety of classical field theories in such a way that the resulting “covariantized” theories are éssentially equivalent to the originals. In particular, our technique will render many class[...]texto impreso
Bonet Fernández, Juan Manuel ; Aroca Aguilar, José Daniel ; Corton Pérez, Marta ; Ramírez Sebastián, Ana Isabel ; Alexandre Moreno, Susana ; García Antón, María Teresa ; Salazar Corral, Juan José ; Ferre Fernández, Jesús José ; Atienzar Aroca, Raquel ; Villaverde Montero, Cristina ; Iancu, Ionut ; Tamayo Durán, Alejandra ; Méndez Hernández, Carmen D. ; Morales Fernández, Laura ; Rojas López, Blanca ; Ayuso García, Carmen ; Coca Prados, Miguel ; Martínez de la Casa, Jose Maria ; García Feijoo, Julián ; Escribano, Julio | Springer-Verlag | 2020-04-09Abnormal development of the ocular anterior segment may lead to a spectrum of clinical phenotypes ranging from primary congenital glaucoma (PCG) to variable anterior segment dysgenesis (ASD). The main objective of this study was to identify the [...]texto impreso
Magnini, Bernardo ; Romagnoli, Simone ; Vallin, Alessandro ; Herrera, Jesús ; Peñas, Anselmo ; Peinado, Víctor ; Verdejo, Felisa ; de Rijke, Maarten | Springer-Verlag | 2004This paper describes the procedure adopted by the three coordinators of the CLEF 2003 question answering track (ITC-irst, UNED and ILLC) to create the question set for the monolingual tasks. Despite the few resources available, the three groups [...]texto impreso
Gallego Rodrigo, Francisco Javier ; González Andrés, Miguel ; Purnaprajna, Bangere P. | Springer-Verlag | 2010-06-05In this article we study the deformation of finite maps and show how to use this deformation theory to construct varieties with given invariants in a projective space. Among other things, we prove a criterion that determines when a finite map ca[...]texto impreso
Organista, Elia ; Domínguez-Rodrigo, Manuel ; Egeland, Charles P. ; Uribelarrea del Val, David ; Mabulla, Audax ; Baquedano, Enrique | Springer-Verlag | 2016-09New research and excavations at Bell Korongo (BK, Olduvai Gorge, Upper Bed II) have uncovered a dense concentration of megafauna that contributes to our understanding of Homo erectus subsistence strategies around 1.34 Ma. Recent work has yielded[...]texto impreso
The time dependence of deviations from the Gaussian state in a freely cooling homogeneous system of smooth inelastically colliding spheres is investigated by kinetic theory. We determine the full time dependence of the coefficients of an expansi[...]texto impreso
We introduced previously an on-line resource, RANKPEP that uses position specific scoring matrices (PSSMs) or profiles for the prediction of peptide-MHC class I (MHCI) binding as a basis for CD8 T-cell epitope identification. Here, using PSSMs t[...]texto impreso

Ventre-Lespiaucq, Agustina B. ; Escribano Rocafort, Adrián Gaspar ; Delgado Sáez, Juan Antonio ; Jiménez Escobar, María Dolores ; Rubio de Casas, Rafael ; Granado Yela, Carlos ; Balaguer Núñez, Luis | Springer-Verlag | 2016-06The light environment within a tree crown can be characterized by specific variation patterns arising from the structural features of the crown. Within-crown light variation patterns can be important for plant productivity, but this has yet to b[...]texto impreso
Supervised classification in remote sensing is a very complex problem and involves steps of different nature, including a serious data preprocessing. The final objective can be stated in terms of a classification of isolated pixels between class[...]texto impreso
García Quintana, Álvaro ; Martín Duque, José Francisco ; González Martín, Francisco Javier ; García Hidalgo, J.F. ; Pedraza Gilsanz, Javier de ; Herranz Araújo, Pedro ; Rincón, R. ; Estévez Martín, Hugo | Springer-Verlag | 2005Methods commonly used in regional geological analysis were employed to study the visual landscapes of the Sigüenza–Molina de Aragón area (Spain). Landscape data were compiled to produce a landscape map and a photograph catalogue. Lithological co[...]texto impreso

Barrio Asensio, María del Carmen ; Murillo González, Jorge Alfonso ; Peña Melián, Ángel ; Puerta Fonollá, Javier | Springer-Verlag | 1999-10The ontogenic development of the sphincter iris has been studied by immunocytochemistry and standard staining on chick embryos from stage 25 HH to the time of hatching. We have used the monoclonal antibody 13F4, a highly specific marker of muscu[...]texto impreso
The continuous Hopfield network (CHN) can be used to solve, among other combinatorial optimization problems, the traveling salesman problem (TSP). In order to improve the performance of this heuristic technique, a divide-and-conquer strategy bas[...]texto impreso
López Alonso, Covadonga ; Fernández-Pampillón Cesteros, Ana María ; De Miguel García, Elena ; Pita Puértolas, Gustavo | Springer-Verlag | 2008Learning is the basis for research and lifelong training. The implementation of virtual environments for developing this competency requires the use of effective learning models. In this study we present an experiment in positive learning from t[...]texto impreso

Minimung-divergence functionals and their associated estimators are defined. The estimators are based on a non-parametric density estimator. Existence and robustness of the functional and convergence of the estimator are proved. (Spanish:Se intr[...]
