Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Spectral distribution of a double-well Duffing oscillator subject to a random force.
No full textThe power spectral density Q(w) for an electronic circuit model of the double-well Duffing oscillator, driven by Gaussian white noise, has been measured in the limit of very low damping. Three distinct maxima and a plateau region are found in Q(w), in excellent qualitative agreement with a recent theoretical prediction by Dykman and co-workers
Noise in Nonlinear Dynamical Systems. Volume 2. Theory of noise induced processes in special applications
No full textNature is inherently noisy and nonlinear. It is noisy in the sense that all macroscopic systems are subject to the fluctuations of their environments and also to internal fluctuations. It is nonlinear in the sense that the restoring force on a system displaced from equilibrium does not usually vary linearly with the size of the displacement. To calculate the properties of stochastic (noisy) nonlinear systems is in general extremely difficult, although considerable progress has now been made, particularly during the past two decades. The three volumes that make up Noise in nonlinear dynamical systems comprise a collection of specially written authoritative reviews on all aspects of the subject, representative of all the major practitioners in the field. It is anticipated that this work will help to stimulate new research, and that it will be of value to all those entering or already working in the field by bringing together all the experimental and theoretical tools needed. The books will be of interest not only to researchers in statistical physics, but also to those people working in relevant areas of chemistry, engineering and biology. and many other branches of science and technology. The second volume applies the theory of Volume 1 to the calculation of the influence of noise in a variety of contexts. These include quantum mechanics, condensed matter, noise induced transitions, escape processes and transition probabilities, systems with periodic potentials, discrete nonlinear systems, symmetry-breaking transition, and optics
Postponed bifurcations of a ring-laser model with a swept parameter and additive colored noise.
Full text linkWe present measurements of the time evolution of the statistical densities of both amplitude and field intensity obtained from a colored-noise-driven electronic circuit model of a ring laser, as the bifurcation parameter is swept through its critical values. The time-dependent second moments (intensities) were obtained from the densities. In addition, the individual stochastic trajectories were available from which the distribution of bifurcation times was constructed. For short-correlation time (quasiwhite) noise our results are in quantitative agreement with the recent calculations of Boggi, Colombo, Lugiato, and Mandel [Phys. Rev. A 33, 3635 (1986)]. New results for long noise correlation times are obtained

The third volume deals with experimental aspects of the study of noise in nonlinear dynamical systems. It covers noise-driven phenomena in superfluid helium, liquid crystals, lasers and optical bistability as well as the solution of stochastic equations by digital simulation and analogue experiment
