A dynamical model of cancer chemotherapy with disturbance

Proceedings of the 14th annual conference companion on Genetic and evolutionary computation, 2012
This work proposes a controlled stochastic difference equation model of scheduling, with quadratic cost criteria, for cancer chemotherapy. By reducing the problem to quadratic control optimization and introducing a random search algorithm, we seek an optimal chemotherapy schedule.

Landscape Disturbance Dynamics

2015
Disturbances are integral to ecological systems and affect landscapes across a wide range of scales. The causes of disturbance, the patterns and dynamics they produce, their ecological consequences are major research topics in landscape ecology. Interest stemmed initially from recognition that disturbance was a conspicuous agent of pattern formation ...

Disturbed mitochondrial dynamics and neurodegenerative disorders

Nature Reviews Neurology, 2014
Mitochondria form a highly interconnected tubular network throughout the cell via a dynamic process, with mitochondrial segments fusing and breaking apart continuously. Strong evidence has emerged to implicate disturbed mitochondrial fusion and fission as central pathological components underpinning a number of childhood and adult-onset ...

Disturbance impacts on forest temporal dynamics

Water, Air, & Soil Pollution, 1995
Contagious disturbances are widespread and an important component of the life-cycle of the Canadian boreal forest. Models which simulate the dynamics of these forests must include a representation of disturbance influences. Spatial models differ from non-spatial models in the use of area-based rather than point-based sampling designs.

Disturbance and landscape dynamics in a changing world

Ecology, 2010
Disturbance regimes are changing rapidly, and the consequences of such changes for ecosystems and linked social‐ecological systems will be profound. This paper synthesizes current understanding of disturbance with an emphasis on fundamental contributions to contemporary landscape and ecosystem ecology, then identifies future research priorities ...

Microgravity environment dynamic disturbances

Acta Astronautica, 1993
Abstract The microgravity environment on-board an Earth orbiting spacecraft provides various opportunities in utilization of experimental and application fields of fluid, materials and life sciences. The design of such spacecraft shall maintain a quality of the microgravity environment in terms of limit acceleration levels. The residual accelerations

Transience after disturbance: Obligate species recovery dynamics depend on disturbance duration

Theoretical Population Biology, 2017
After a disturbance event, population recovery becomes an important species response that drives ecosystem dynamics. Yet, it is unclear how interspecific interactions impact species recovery from a disturbance and which role the disturbance duration (pulse or press) plays.

Western Disturbances – Dynamics and Thermodynamics

2016
To further expand our knowledge of the weather systems called western disturbances (WDs), in this chapter we present the dynamical basis of WDs. The mechanism of WD formation with details on the evolution of such storms are discussed, and a detailed explanation of the energetics and thermodynamics of the winter storms provided.

Rejection of disturbance with nonlinear dynamics

Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999
Linear feedback control based on internal model principle achieves asymptotic tracking for linear system with known linear exogenous signal dynamics. This paper investigates the case of rejecting exogenous chaotic signals with known nonlinear dynamics for linear systems in the discrete time domain.
