Control theory in biology and medicine

From September–December 2017, the Mathematical Biosciences Institute at Ohio State University hosted a series of workshops on control theory in biology and medicine, including workshops on control ... of the participants in the MBI workshops. Control theory is a mathematically oriented discipline within engineering that concerns the design and analysis of systems for the regulation of physical

Turning Motion Control Design of a Two-Wheeled Inverted Pendulum Using Curvature Tracking and Optimal Control Theory

This paper presents a control design method for implementing planar turning motion of a two-wheeled inverted pendulum with an input delay. The control task requires that the inverted pendulum is kept ... more widely used in human transporters and humanoid robots. However, the dynamics analysis and motion control design of TWIP systems are still challenging, because a TWIP is an essential nonlinear and

Restriction-modification systems in Mycoplasma spp

repeats within their coding sequences, indicating that their expression is under the control of phase variation mechanisms. Altogether, these data suggest that R-M systems are a remarkable characteristic of ... Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil Send correspondence to     ABSTRACT Restriction and Modification (R-M) systems are present in all Mycoplasma species sequenced so far. The

Optimality theory and historical phonology: an example from nasal harmony in Mundurukú

This paper offers an account of diachronic changes in nasal harmony in Mundurukú, a Tupian language from Brazil. It attempts to show that the Optimality Theory provides new ways of accounting for ... Kuruaya's modern systems points out that the source system, Proto-Mundurukú, had similar properties to those currently observed in Kuruaya. In particular, nasal spread targets were voiced stops and sonorants

Disturbance rejection via iterative learning control with a disturbance observer for active magnetic bearing systems

Although standard iterative learning control (ILC) approaches can achieve perfect tracking for active magnetic bearing (AMB) systems under external disturbances, the disturbances are required to be ... existing approaches, we address the tracking control problem of AMB systems under iteration-variant disturbances that are in different channels from the control inputs. A disturbance observer based ILC

Application of the mammalian glyceraldehyde-3-phosphate dehydrogenase gene for sample quality control in multiplex PCR for diagnosis of leishmaniasis

. Molecular methods to detect Leishmania are considered alternatives to overcome the limitations presented by conventional methods. The aim of this study was to develop multiplex PCR systems able to detect ... multiplex PCR systems. For a preliminary assessment of G3PD gene systems, an experiment was conducted in which the reaction was composed of sample without DNA (negative control), dog blood samples that tested

Asymmetry in reproduction strategies drives evolution of resistance in biological control systems

The success of biological control may depend on the control agent co-evolving with its target pest species, precluding the emergence of resistance that often undermines chemical control. However ... (Fenner 1983), to our knowledge they have not been considered in the context of biological control when pathogens are not the control agent [ 16 ]. In host-parasitoid biological control systems, there

Generation and control of helium-filled soap bubbles for PIV

. This study provides guidelines for operating HFSB generation systems, intended for PIV experiments.Graphical abstract Open image in new window ... regimes have not been included in the research. Proper control of the generation of conventional micrometer oil particles is nowadays guaranteed, where a detailed study of atomizer nozzles (Kähler et al

Systems Theory

Systems Theory has generated a lot of excitement in the last decade. It has also spawned more than its share of pitchmen, enough so that it is in danger of being discredited before its genuine ... most promising, and also the most difficult, aspect of systems theory for the social work practitioner is the topic of "feedback" and its implications for power and social control. Here the organismic

Correction to: Density functional theory studies on PVDF/ionic liquid composite systems

Computational details: Partial atomic charge distribution within the systems under study is demonstrated using two types of charge population analysis schemes, a) Mulliken population analysis (MPA) and b ... orbital (LCAO MO) theory. However, the major disadvantage of this population analysis scheme is its high basis set dependence and therefore less reliability compared to HPA method, which is based on

Constraining quantum fields using modular theory

Abstract Tomita-Takesaki modular theory provides a set of algebraic tools in quantum field theory that is suitable for the study of the information-theoretic properties of states. For every open set

Duality in the optimal control for damped hyperbolic systems with positive control

We study the duality theory for damped hyperbolic equations. These systems have positive controls and convex cost functionals. Our main results lie in the application of duality theorem, that is, inf ... ] introduced optimal control problems of the variety of distributed parameter systems, for example, elliptic, parabolic, and hyperbolic. Here, we see that adjoint state systems are given cost functional and

Asymptotically stable equilibrium points in new chaotic systems

. 2Departamento de Matemática, Facultad de Ingeniería y Tecnologías, Universidad Católica del Uruguay, Uruguay. Abstract In this paper ten new chaotic nonlinear autonomous systems are presented. These ... systems were found by using the Monte Carlo method and they characterized by having one of their equilibrium points asymptotically stable. These new systems does not present chaos in the sense of Shilnikov

Epidemiological investigation on envenomation: from theory to practice

A better understanding of the epidemiology of envenoming would improve care, provided that the survey is representative, reliable and accurate. Several types of surveys could help to clarify the incidence, severity, circumstances, factors and determinants of envenomations. The relevant information may be collected and analyzed from hospital records or case report forms (for...

A theory of reparameterizations for AdS3 gravity

Abstract We rewrite the Chern-Simons description of pure gravity on global AdS3 and on Euclidean BTZ black holes as a quantum field theory on the AdS boundary. The resulting theory is (two copies of ... of the boundary gravitons. This theory respects all of the conformal field theory axioms except one: it is not modular invariant. The coupling constant is 1/c with c the central charge, and
