K nearest neighbor equality: giving equal chance to all existing classes
(Elsevier, 2011-07-23)
The nearest neighbor classification method assigns an unclassified point to the class of the nearest case of a set of previously classified points. This rule is independent of the underlying joint distribution of the sample ...
Brillouin spectral scanning using the wavelength dependence of the frequency shift
(IEEE, 2011)
We present a novel Brillouin spectra characterization method based on the Brillouin frequency shift dependence with pump wavelength. It is applied to a Brillouin optical time domain analysis sensor, resulting in a cost ...
Genetic and Environmental Influences on Growth from Late Childhood to Adulthood: A Longitudinal Study of Two Finnish Twin Cohorts
(Wiley, 2011-09-29)
Objectives: Human growth is a complex process that remains insufficiently understood. We aimed to analyze genetic and environmental influences on growth from late childhood to early adulthood.
Methods: Two cohorts of ...
Does forest fragmentation affect the same way all growth-forms?
(Elsevier, 2011-09-15)
Fragmentation of natural habitats is one of the main causes of the loss of biodiversity. However, all plants
do not respond to habitat fragmentation in the same way due to differences in species traits. We studied
the ...
The relationship between store image and store brand equity: A conceptual framework and evidence from hypermarkets
(Elsevier, 2011-09-13)
Retailers are making considerable efforts to improve their brand management. The challenge they face, however, is how best to integrate coherently their stores, as brands, and their various distributor brands (store brands, ...
Evaluation of bioactive sphingolipids in 4-HPR-resistant leukemia cells
(BioMed Central, 2011-10-07)
Background -- N-(4-hydroxyphenyl)retinamide (4-HPR, fenretinide) is a synthetic retinoid with potent pro-apoptotic activity against several types of cancer, but little is known regarding mechanisms leading to chemoresistance. ...
Invariant-Free Clausal Temporal Resolution
(Springer, 2011-12-02)
Resolution is a well-known proof method for classical logics that is well suited for mechanization. The most fruitful approach in the literature on temporal logic, which was started with the seminal paper of M. Fisher, ...
Environmental Taxes and Cross-Ownership
(Universidad de Zaragoza. Facultad de Economía y Empresa, 2011-12-01)
Este artículo analiza el efecto de la propiedad cruzada de las empresas sobre el nivel de protección ambiental que fija un gobierno a través de impuestos medioambientales. Suponemos que hay dos empresas y dos accionistas, ...
Anatomical distribution of lipids in human brain cortex by imaging mass spectrometry
(Springer Verlag, 2011-01-28)
[ES] Las imágenes de masa molecular de los tejidos estarán sesgadas si las diferencias en las propiedades fisicoquímicas del microentorno afectan a la intensidad de los espectros. Para abordar esta cuestión, hemos realizado ...
Conformational Sampling and Nucleotide-Dependent Transitions of the GroEL Subunit Probed by Unbiased Molecular Dynamics Simulations
(Public Library of Science, 2011-03-10)
GroEL is an ATP dependent molecular chaperone that promotes the folding of a large number of substrate proteins in E. coli. Large-scale conformational transitions occurring during the reaction cycle have been characterized ...
