On Chebyshev's Systems and Non-Uniform Sampling Related to Caputo Fractional Dynamic Time-Invariant Systems
(Hindawi Publishing Corporation, 2010)
This paper is concerned with the investigation of the controllability and observability of Caputo fractional differential linear systems of any real order α. Expressions for the expansions of the evolution operators in ...
Linking Contractive Self-Mappings and Cyclic Meir-Keeler Contractions with Kannan Self-Mappings
(Hindawi Publishing Corporation, 2010)
Some mutual relations between p-cyclic contractive self-mappings, p-cyclic Kannan self-mappings, and Meir-Keeler p-cyclic contractions are stated. On the other hand, related results about the existence of the best proximity ...
Ab initio molecular dynamics on the electronic Boltzmann equilibrium distribution
(IOP Publishing, 2010-08-31)
We prove that for a combined system of classical and quantum particles, it is possible to describe a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium population for the ...
Composition and conservation of the mRNA-degrading machinery in bacteria
(BioMed Central, 2011)
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts. Genetic and biochemical data ...
Impaired dermal wound healing in discoidin domain receptor 2-deficient mice associated with defective extracellular matrix remodeling
(BioMed Central, 2011)
Background
The wounding response relies on tightly regulated crosstalk between recruited fibroblasts and the collagenous extracellular matrix (ECM). Discoidin domain receptor 2 (DDR2) is a tyrosine kinase receptor for ...
Variability of indication criteria in knee and hip replacement: an observational study
(BioMed Central, 2010)
Background
Total knee (TKR) and hip (THR) replacement (arthroplasty) are effective surgical procedures that relieve pain, improve patients' quality of life and increase functional capacity. Studies on variations in medical ...
Noisy-threshold control of cell death
(BioMed Central, 2010)
Background
Cellular responses to death-promoting stimuli typically proceed through a differentiated multistage process, involving a lag phase, extensive death, and potential adaptation. Deregulation of this chain of events ...
Isolation of mineralizing Nestin+ Nkx6.1+ vascular muscular cells from the adult human spinal cord
(BioMed Central, 2011-10-10)
Background: The adult central nervous system (CNS) contains different populations of immature cells that could possibly be used to repair brain and spinal cord lesions. The diversity and the properties of these cells in ...
The Oxidative State of Chylomicron Remnants Influences Their Modulation of Human Monocyte Activation
(Hindawi Publishing Corporation, 2012)
Chylomicron remnants (CMRs) contribute directly to human monocyte activation in vitro, by increasing reactive oxygen species (ROS) production and cell migration. In this study, the effects of the oxidative state of CMR on ...
Aproximación al pintor Epifanio Díaz de Arcaute (1845-1910)
(Fundación Sancho el Sabio, 2010)
[ES]Con este trabajo pretendemos aproximarnos a la figura de Epifanio Díaz de Arcaute (1845-1910), un pintor no demasiado conocido y con una producción artística,
por el momento, escasa. Su formación fue tradicional y ...
