Anisotropic low-temperature magnetoresistivity in the normal state of L2−xCexCuO4 single crystals
(1994)We report in-plane ρab(T, H) and c-axis ρc(T, H) electrical magnetoresistivity measurements on several L2−x CexCuO4 (L=Pr, Sm, Nd) superconducting single crystals. It is found that in the normal state ... -
Influence of the g conformation of Ser and Thr on the structure of transmembrane helices
(2010)In order to study the influence of Ser and Thr on the structure of transmembrane helices we have analyzed a database of helix stretches extracted from crystal structures of membrane proteins and an ... -
The invention of lustre: Iraq 9th and 10th centuries AD
(2008)In this paper the study of four significant lustre samples covering 9th century AD polychrome and 10th century AD monochrome lustre from Iraq is presented. The samples selected are representative of ... -
Early Islamic lustre from Egypt, Syria and Iran (10th to 13th century AD)
(2008)This paper presents a study of a representative selection of lustre ceramics dating from the last quarter of the 10th century AD to the second half of the 13th century AD from Egypt, Syria and Iran. ... -
Efecto de 24 semanas de entrenamiento de fuerza a moderada-alta intensidad en ancianos
(2014)Introducción: Los programas de fuerza han demostrado ser beneficiosos para minimizar los efectos de lasarcopenia, aunque los protocolos de intervención presentan características y contenidos en ocasionesmuy ... -
Synchrotron radiation micro-XRD in the study of glaze technology
(2010)The production of glass represented an important technological achievement, and it was the starting point for the invention of a large variety of materials, produced by processes involving melting, ... -
Temperature resolved reproduction of medieval luster
(2008)Luster is a golden metallic-like decoration produced on glazed ceramics since early Islamic times (Iraq, 9th AD). Luster is obtained by the reaction of a luster paint and the glaze surface over which ... -
Two Families of Radix-2 FFT Algorithms With Ordered Input and Output Data
(2009)Two radix-2 families of fast Fourier transform (FFT) algorithms that have the property that both inputs and outputs are addressed in natural order are derived in this letter. The algorithms obtained ... -
On the central configurations of the planar 1 + 3 body problem
(2011)We consider the Newtonian four-body problem in the plane with a dominat mass M. We study the planar central configurations of this problem when the remaining masses are infinitesimal. We obtain two ... -
Risk of HIV infection as a function of the duration of intravenous drug use: a non-parametric Bayesian approach
(2000)We analyse the elapsed time between intravenous (IV) drug initiation and HIV infection in a cohort of 972 injecting drug users attending a hospital detoxi cation unit. We use the time of seroconversion ... -
Model-Based Multifactor Dimensionality Reduction for detecting epistasis in case–control data in the presence of noise
(2011)Analyzing the combined effects of genes and/or environmental factors on the development of complex diseases is a great challenge from both the statistical and computational perspective, even using a ... -
mbmdr: an R package for exploring gene–gene interactions associated with binary or quantitative traits
(2010)Summary: We describe mbmdr, an R package for implementing the model-based multifactor dimensionality reduction (MB-MDR) method. MB-MDR has been proposed by Calle et al. as a dimension reduction method ... -
A Semiparametric hierarchical method for a regression model with an interval-censored covariate
(2005)A Bayesian framework is proposed for analysing regression models in which one of the covariates is interval-censored. Such a situation was encountered in an AIDS clinical trial in which the goal was ... -
Respirometric screening of several types of manure and mixtures intended for composting
(2011)The viability of mixtures from manure and agricultural wastes as composting sources were systematically studied using a physicochemical and biological characterization. The combination of different parameters ... -
Color and Golden Shine of Silver Islamic Luster
(2010)Golden-like luster decorations on glazed ceramics from early Islamic times (9–12th centuries AD) consist of a nanocomposite submicrometric layer made of silver metal nanoparticles. The color and ... -
AUC-RF: A New Strategy for Genomic Profiling with Random Forest
(2011)Objective: Genomic profiling, the use of genetic variants at multiple loci simultaneously for the prediction of disease risk, requires the selection of a set of genetic variants that best predicts ... -
Nonparametric Bayesian estimation from interval-censored data using Monte Carlo methods
(2001)We study the estimation of the survival function based on interval-censored data from a nonparametric Bayesian point of view. Interval censoring arises when the time variable of interest cannot be ... -
Soil water regime through contrasting pasture communities in a Submediterranean landscape
(2007)Submediterranean landscape around Vic includes, scattered over intensively farmed ground, a number of hills holding diverse mosaics of natural and seminatural communities. We chose two contrasting ... -
Influence of storage temperature on the quality of beef liver; pH as a reliable indicator of beef liver spoilage
(1999)The development of the microbial flora specifically involved in the spoilage of sliced beef livers packaged and stored under aerobic conditions at 0 and 3 °C for 14 days was studied. Changes in the pH ...
