About Robust Stability of Caputo Linear Fractional Dynamic Systems with Time Delays through Fixed Point Theory
(Hindawi Publishing Corporation, 2011)
This paper investigates the global stability and the global asymptotic stability independent of the sizes of the delays of linear time-varying Caputo fractional dynamic systems of real fractional order possessing internal ...
Time-dependent electron phenomena at surfaces
(US National Academy of Sciences, 2011-01)
Femtosecond and subfemtosecond time scales typically rule electron dynamics at metal surfaces. Recent advance in experimental techniques permits now remarkable precision in the description of these processes. In particular, ...
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 ...
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 ...
Energy and information in Hodgkin-Huxley neurons
(American Physical Society, 2011-03-21)
[EN]The generation of spikes by neurons is energetically a costly process and the evaluation of the metabolic energy required to maintain the signaling activity of neurons a challenge of practical interest. Neuron models ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
(Elsevier, 2011-01)
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens
(MDPI, 2011-01)
This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme ...
Elucidation of Functional Markers from Aspergillus nidulans Developmental Regulator FlbB and Their Phylogenetic Distribution
(Public Library of Science, 2011-03-10)
Aspergillus nidulans is a filamentous fungus widely used as a model for biotechnological and clinical research. It is also used as a platform for the study of basic eukaryotic developmental processes. Previous studies ...
Evaluation of a Programme for Computer-Assisted Learning
(Universidad del País Vasco / Euskal Herriko Unibertsitatea, 2011)
[En] This article lies within the framework of the implementation and use of ICT as a medium of learning in Primary Education. A learning programme was created, implemented and evaluated through using the computer known ...
