Self-Similarity and helical symmetry in vortex generator flow simulations
(IOP Publishing, 2014)
According to experimental observations, the vortices generated by vortex generators have previously been observed to be self-similar for both the axial (u(z)) and azimuthal (u(circle minus)) velocity profiles. Further, the ...
Viability Conditions for a Compartmentalized Protometabolic System: A Semi-Empirical Approach
(Public Library Science, 2012-06)
In this work we attempt to find out the extent to which realistic prebiotic compartments, such as fatty acid vesicles, would constrain the chemical network dynamics that could have sustained a minimal form of metabolism. ...
Rhythm Analysis during Cardiopulmonary Resuscitation: Past, Present, and Future
(Hindawi, 2014-01)
Survival from out-of-hospital cardiac arrest depends largely on two factors: early cardiopulmonary resuscitation (CPR) and early defibrillation. CPR must be interrupted for a reliable automated rhythm analysis because chest ...
Intracellular Ca2+ release through ryanodine receptors contributes to AMPA receptor-mediated mitochondrial dysfunction and ER stress in oligodendrocytes
(Nature Publishing Group, 2010-07)
Overactivation of ionotropic glutamate receptors in oligodendrocytes induces cytosolic Ca2+ overload and excitotoxic death, a process that contributes to demyelination and multiple sclerosis. Excitotoxic insults cause ...
1-42 beta-Amyloid peptide requires PDK1/nPKC/Rac 1 pathway to induce neuronal death
(Nature Publishing Group, 2013-01)
1-42 beta-Amyloid (A beta(1-42)) peptide is a key molecule involved in the development of Alzheimer's disease. Some of its effects are manifested at the neuronal morphological level. These morphological changes involve ...
Identification of the main allergen sensitizers in an Iran asthmatic population by molecular diagnosis
(Biomed Central, 2014-08-05)
Background: There has been a significant growth in the prevalence of allergy, mainly associated to IgE-mediated disorders such as asthma and rhinitis. The identification of atopy in asthmatic patients through the measurement ...
Digital Quantum Rabi and Dicke Models in Superconducting Circuits
(Nature Publishing Group, 2014-12-15)
We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in ...
The Forbidden Quantum Adder
(Nature Publishing Group, 2015-07-08)
Quantum information provides fundamentally different computational resources than classical information. We prove that there is no unitary protocol able to add unknown quantum states belonging to different Hilbert spaces. ...
Specific Interaction with Cardiolipin Triggers Functional Activation of Dynamin-Related Protein 1
(Public Library Science, 2014-07-18)
Dynamin-Related Protein 1 (Drp1), a large GTPase of the dynamin superfamily, is required for mitochondrial fission in healthy and apoptotic cells. Drp1 activation is a complex process that involves translocation from the ...
Evaluation of Fentanyl Disposition and Effects in Newborn Piglets as an Experimental Model for Human Neonates
(Public Library Science, 2014-03-04)
Background: Fentanyl is widely used off-label in NICU. Our aim was to investigate its cerebral, cardiovascular and pulmonary effects as well as pharmacokinetics in an experimental model for neonates.
Methods: Fentanyl ...
