La reforma del sistema internacional de cooperación frente al horizonte post-2015: retos, propuestas y realidades
(Sociedad de Economía Mundial, 2014)
Este artículo pretende analizar los principales debates y aportaciones realizados
en el ámbito de los estudios e investigaciones sobre el desarrollo y la
cooperación en las últimas décadas, así como las resoluciones y ...
Robust Adaptive Stabilization of Linear Time-Invariant Dynamic Systems by Using Fractional-Order Holds and Multirate Sampling Controls
(Hindawi Publishing Corporation, 2010-02)
This paper presents a strategy for designing a robust discrete-time adaptive controller for stabilizing linear time-invariant (LTI) continuous-time dynamic systems. Such systems may be unstable and noninversely stable in ...
Mechanistic Insights in the Mode of Action of Bifunctional Pyrrolidine-Squaramide-derived Organocatalysts
(Wiley-VCH, 2016)
The modes of catalytic action of three squaramide-derived
bifunctional organocatalysts have been investigated using DFT
methods. The [5+2] cycloaddition between oxidopyrilium ylides and
enals has been used as model ...
α2,3-Sialyltransferase ST3Gal III Modulates Pancreatic Cancer Cell Motility and Adhesion In Vitro and Enhances Its Metastatic Potential In Vivo
(Public Library of Science, 2010-09-01)
Background: Cell surface sialylation is emerging as an important feature of cancer cell metastasis. Sialyltransferase expression has been reported to be altered in tumours and may account for the formation of sialylated ...
Nueva York, Monterrey y París: tres lógicas contradictorias para enfrentar los retos del desarrollo en la primera década del siglo
(Universidad de Zaragoza, 2012)
Este trabajo analiza las contradictorias lógicas planteadas a lo largo de la primera década del siglo xxi
desde los principales foros internacionales en los que se ha debatido sobre la cooperación al desarrollo.

On the Existence of Equilibrium Points, Boundedness, Oscillating Behavior and Positivity of a SVEIRS Epidemic Model under Constant and Impulsive Vaccination
(Hindawi Publishing Corporation, 2011)
This paper discusses the disease-free and endemic equilibrium points of a SVEIRS propagation disease model which potentially involves a regular constant vaccination. The positivity of such a model is also discussed as well ...
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 ...
Positivity and Stability of the Solutions of Caputo Fractional Linear Time-Invariant Systems of Any Order with Internal Point Delays
(Hindawi Publishing Corporation, 2011)
This paper is devoted to the investigation of the nonnegative solutions and the stability and asymptotic properties of the solutions of fractional differential dynamic systems involving delayed dynamics with point delays. ...
Video Quality Prediction Models Based on Video Content Dynamics for H.264 Video over UMTS Networks
(Hindawi Publishing Corporation, 2010)
The aim of this paper is to present video quality prediction models for objective non-intrusive, prediction of H.264 encoded video for all content types combining parameters both in the physical and application layer over ...
Grafted Human Embryonic Progenitors Expressing Neurogenin-2 Stimulate Axonal Sprouting and Improve Motor Recovery after Severe Spinal Cord Injury
(Public Library of Science, 2010-12-30)
Background: Spinal cord injury (SCI) is a widely spread pathology with currently no effective treatment for any symptom. Regenerative medicine through cell transplantation is a very attractive strategy and may be used in ...
