Surface ionization of metastable calcium atoms
AIP Advances, 2021 We report on an experimental study of surface ionization of metastable calcium atoms on a hot polycrystalline tungsten surface in vacuum. We implemented a hollow-cathode discharge to excite a fraction of calcium atoms in an atomic beam to metastable ...

Epilepsy and Nonlinear Dynamics [PDF]
Journal of Biological Physics, 2008 This overview summarizes findings obtained from analyzing electroencephalographic (EEG) recordings from epilepsy patients with methods from the theory of nonlinear dynamical systems. The last two decades have shown that nonlinear time series analysis techniques allow an improved characterization of epileptic brain states and help to gain deeper ...

Nanoscopic imaging of thick heterogeneous soft-matter structures in aqueous solution
Nature Communications, 2016 Integration time limits the capacity of super-resolution microscopy to study dynamics. Here, Bartsch et al. use the 3D scanning of a nanoparticle held in an optical trap, and its thermal noise motion within the trap, to image the local dynamics of soft ...

Neimark-Sacker Bifurcation in a Discrete-Time Financial System
Discrete Dynamics in Nature and Society, 2010 A discrete-time financial system is proposed by using forward Euler scheme. Based on explicit Neimark-Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal form method and center manifold theory, the system's existence, stability ...

Complex Dynamics of an Adnascent-Type Game Model
Discrete Dynamics in Nature and Society, 2008 The paper presents a nonlinear discrete game model for two oligopolistic firms whose products are adnascent. (In biology, the term adnascent has only one sense, “growing to or on something else,” e.g., “moss is an adnascent plant.” See Webster's Revised ...

Nonlinear Dynamics in Psychology
Discrete Dynamics in Nature and Society, 2001 This article provides a survey of the applications of nonlinear dynamical systems theory to substantive problems encountered in the full scope of psychological science. Applications are organized into three topical areas – cognitive science, social and organizational psychology, and personality and clinical psychology.

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]
, 2011 In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.

Nonlinear Drillstring Dynamics Analysis [PDF]
SIAM Journal on Applied Dynamical Systems, 2009 This paper studies the dynamical response of a rotary drilling system with a drag bit, using a lumped parameter model that takes into consideration the axial and torsional vibration modes of the bit. These vibrations are coupled through a bit-rock interaction law.
