Entropic nonextensivity as a measure of time series complexity
(Physica A: Statistical Mechanics and Its Applications, 2004)
Information entropy is applied to the analysis of time series generated by dynamical systems. Complexity of a temporal or spatio-temporal signal is defined as the difference between the sum of entropies of the local linear ...
Gamma irradiation processing of hydroxyapatite/poly-L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2003)
Effects of gamma irradiation on structure and physicochemical properties of the hydroxyapatite/poly-L-lactide (HAp/PLLA) composite were studied in this paper. Since the morphology of HAp/PLLA is very sensitive to gamma ...
Anti-IgG antibodies from sera of healthy individuals neutralize HIV-1 primary isolates
(Current HIV Research, 2007)
Immunoglobulins (Ig) of pooled healthy human sera were purified by affinity chromatography based on their reactivity with human IgG. This Ig fraction represent connected, natural antibodies (NAbs) and here are denoted as ...
Investigation of the projectile atomic number influence to the total sputtering yield in the keV energy region
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
The non-monotonous dependence of the total sputtering yield on the projectile atomic number, which is unexpected in the frame of the Sigmund linear cascade theory, is investigated using Monte Carlo simulations (program ...
Closed-form evaluation of some families of cotangent and cosecant integrals
(Integral Transforms and Special Functions, 2008)
Several families of integrals involving the cotangent or cosecant function have been evaluated in closed form by making use of elementary arguments. Some of them are expressible in terms of the values of the (generalized) ...
Bifurcations in nonlinear models of fluid-conveying pipes supported at both ends
(Journal of Fluids and Structures, 2006)
Stationary bifurcations in several nonlinear models of fluid conveying pipes fixed at both ends are analyzed with the use of Lyapunov-Schrnidt reduction and singularity theory. Influence of the gravitational force, curvature ...
Nanoengineering of inorganic and hybrid composites
(Materials Science Forum, 2000)
The engineering of materials and devices on the nanometer scale is of considerable current interest in electronics, optics, catalysis, ceramics and magnetic storage. Different methodologies of processing that lead to the ...
Optical properties of Hg1-xMnxTe1-ySey
(Infrared Physics and Technology, 2005)
Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared ...
Thermodynamic limit for the Ising model on the Cayley tree
(Physica A: Statistical Mechanics and Its Applications, 2005)
While the Ising model on the Cayley tree has no spontaneous magnetization at nonzero temperatures in the thermodynamic limit, we show that finite systems of astronomical sizes remain magnetically ordered in a wide temperature ...
The CMS high level trigger
(European Physical Journal C. Particles and Fields, 2006)
At the Large Hadron Collider at CERN the proton bunches cross at a rate of 40 MHz. At the Compact Muon Solenoid experiment the original collision rate is reduced by a factor of O (1000) using a Level-1 hardware trigger. A ...
