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 ...
Modeling of inherent SO2 capture in coal particles during combustion in fluidized bed
(Chemical Engineering Science, 2006)
The process of inherent sulfur capture in coal particles during combustion in fluidized bed was modeled. The significance of the process is in fact that a part of sulfur may be retained in ash, decreasing emission of sulfur ...
Canonical approach to 2D supersymmetric WZNW model coupled to supergravity
(Modern Physics Letters A, 2002)
Starting from the known representation of the Kac-Moody algebra in terms of the coordinates and momenta, we extend it to the representation of the super Kac-Moody and super Virasoro algebras. Then we use general canonical ...
Centering of the ion trajectory in the cyclotron
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
In this paper we present the theory of the horizontal motion ions through the acceleration gap in the case of a static magnetic field and time-varying electric field. It also describes the motion of the center of the ion ...
Comment on Theory of the central ion trajectory in the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2003)
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 ...
