A Minimal Model of Metabolism-Based Chemotaxis
(Public Library of Science, 2010-12-02)Since the pioneering work by Julius Adler in the 1960's, bacterial chemotaxis has been predominantly studied as metabolism-independent. All available simulation models of bacterial chemotaxis endorse this assumption. Recent ... -
About the stability and positivity of a class of discrete nonlinear systems of difference equations
(Hindawi Publishing Corporation, 2008)This paper investigates stability conditions and positivity of the solutions of a coupled set of nonlinear difference equations under very generic conditions of the nonlinear real functions which are assumed to be bounded ... -
About the Stabilization of a Nonlinear Perturbed Difference Equation
(Hindawi Publishing Corporation, 2012)This paper investigates the local asymptotic stabilization of a very general class of instable autonomous nonlinear difference equations which are subject to perturbed dynamics which can have a different order than that ... -
Adaptive control of single-input single-output hybrid systems possessing interacting discrete- and continuous-time dynamics
(Hindawi Publishing Corporation, 2005)This paper deals with the problem of synthesizing a robust adaptive controller for a specific class of single-input single-output (SISO) time-invariant hybrid controlled object (plant) which can operate under bounded ... -
Adaptive control of time-invariant systems with discrete delays subject to multiestimation
(Hindawi Publishing Corporation, 2006)This paper deals with a robustly stable adaptive pole-placement-based controller for time-delay linear systems with unknown point delays within known intervals of sufficiently small lengths under unmodeled dynamics and ... -
Common Fixed Points of Generalized Rational Type Cocyclic Mappings in Multiplicative Metric Spaces
(Hindawi Publishing Corporation, 2015)The aim of this paper is to present fixed point result of mappings satisfying a generalized rational contractive condition in the setup of multiplicative metric spaces. As an application, we obtain a common fixed point of ... -
Conformational Sampling and Nucleotide-Dependent Transitions of the GroEL Subunit Probed by Unbiased Molecular Dynamics Simulations
(Public Library of Science, 2011-03-10)GroEL is an ATP dependent molecular chaperone that promotes the folding of a large number of substrate proteins in E. coli. Large-scale conformational transitions occurring during the reaction cycle have been characterized ... -

Fractional hold circuits versus positive realness of discrete transfer functions
(Hindawi Publishing Corporation, 2005)The appropriate use of fractional-order holds(beta-FROH) of correcting gains beta is an element of[- 1,1] as an alternative to the classical zero- and first-order holds(ZOHs, FOHs) is discussed related to the positive ... -
Hyers-Ulam-Rassias Stability of Functional Differential Systems with Point and Distributed Delays
(Hindawi Publishing Corporation, 2015)This paper investigates stability and asymptotic properties of the error with respect to its nominal version of a nonlinear time-varying perturbed functional differential system subject to point, finite-distributed, and ... -
Model-matching-based control of the Beverton-Holt equation in Ecology
(Hindawi Publishing Corporation, 2008)Beverton-Holt equation of Ecology has a prescribed solution. The way used to achieve the tracking objective is the design of a carrying capacity through a feedback law so that the prescribed reference sequence, which defines ... -
Noisy-threshold control of cell death
(BioMed Central, 2010)Background Cellular responses to death-promoting stimuli typically proceed through a differentiated multistage process, involving a lag phase, extensive death, and potential adaptation. Deregulation of this chain of events ... -
Observer-Based Vaccination Strategy for a True Mass Action SEIR Epidemic Model with Potential Estimation of All the Populations
(Hindawi Publishing Corporation, 2011)This paper presents a simple continuous-time linear vaccination-based control strategy for a SEIR (susceptible plus infected plus infectious plus removed populations) propagation disease model. The model takes into account ... -
