Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
(IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ...
Beta-Glucans Improve Growth, Viability and Colonization of Probiotic Microorganisms
(MDPI, 2012-05-18)
Probiotics, prebiotics and synbiotics are frequently-used components for the elaboration of functional food. Currently, most of the commercialized probiotics are limited to a few strains of the genera Bifidobacteria, ...
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. ...
Stability and Limit Oscillations of a Control Event-Based Sampling Criterion
(Hindawi Publishing Corporation, 2012)
This paper investigates the presence of limit oscillations in an adaptive sampling system. The basic sampling criterion operates in the sense that each next sampling occurs when the absolute difference of the signal amplitude ...
The cross layer RMPA handover: a reliable mobility pattern aware handover strategy for broadband wireless communication in a high-speed railway domain
(Springer, 2012)
Enhancing the handover process in broadband wireless communication deployment has traditionally motivated many research initiatives. In a high-speed railway domain, the challenge is even greater. Owing to the long distances ...
Analytical efficiency evaluation of a network mobility management protocol for Intelligent Transportation Systems
(Springer, 2012)
One of the major concerns in an Intelligent Transportation System (ITS) scenario, such as that which may be found on a long-distance train service, is the provision of efficient communication services, satisfying users' ...
ICGE: an R package for detecting relevant clusters and atypical units in gene expression
(BioMed Central, 2012-02)
Background: Gene expression technologies have opened up new ways to diagnose and treat cancer and other diseases. Clustering algorithms are a useful approach with which to analyze genome expression data. They attempt to ...
Robust Sliding Mode Control for Tokamaks
(Hindawi Publishing Corporation, 2012)
Nuclear fusion has arisen as an alternative energy to avoid carbon dioxide emissions, being the tokamak a promising nuclear fusion reactor that uses a magnetic field to confine plasma in the shape of a torus. However, ...
A quantitative witness for Greenberger-Horne-Zeilinger entanglement
(Nature Publishing Group, 2012-12)
Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for ...
Optimally robust shortcuts to population inversion in two-level quantum systems
(IOP Publishing LTD, 2012-09-21)
We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by ...
