Disentanglement Dynamics in Nonequilibrium Environments
Entropy, 2022 We theoretically study the non-Markovian disentanglement dynamics of a two-qubit system coupled to nonequilibrium environments with nonstationary and non-Markovian random telegraph noise statistical properties. The reduced density matrix of the two-qubit system can be expressed as the Kraus representation in terms of the tensor products of the single ...

Hyper-Selection in Dynamic Environments [PDF]
2008 IEEE Congress on Evolutionary Computation (IEEE World Congress on Computational Intelligence), 2008 In recent years, several approaches have been developed for genetic algorithms to enhance their performance in dynamic environments. Among these approaches, one kind of methods is to adapt genetic operators in order for genetic algorithms to adapt to a new environment.

EDEN: evolutionary dynamics within environments [PDF]
Bioinformatics, 2017 AbstractSummaryMetagenomics revolutionized the field of microbial ecology, giving access to Gb-sized datasets of microbial communities under natural conditions. This enables fine-grained analyses of the functions of community members, studies of their association with phenotypes and environments, as well as of their microevolution and adaptation to ...

Mutator dynamics in fluctuating environments [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002 Populations with high mutation rates (mutator clones) are being found in increasing numbers of species, and a clear link is being established between the presence of mutator clones and drug resistance. Mutator clones exist despite the fact that in a constant environment most mutations are deleterious, with the spontaneous mutation rate generally held ...

Reaction Dynamics within a Cluster Environment
Physical Chemistry Chemical Physics, 2022 This perspective article reviews experimental and theoretical works where rare gas clusters and helium nanodroplet are used as nanoreactor to investigate chemical dynamics in a solvent environment. A historical perspective is presented first, then specific considerations on the mobility of reactants within these reaction media.

Dynamical decoupling in common environment [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2012 Dynamical decoupling (DD) sequences were invented to eliminate the direct coupling between qubit and its environment. We further investigate the possibility of decoupling the indirect qubit-qubit interaction induced by a common environment, and sucessfully find simplified solutions that preserve the bipartite quantum states to arbitrary order.

Asset Return Dynamics under Bad Environment-Good Environment Fundamentals [PDF]
SSRN Electronic Journal, 2010 We introduce a "bad environment-good environment" technology for consumption growth in a consumption-based asset pricing model. Using the preference structure from Campbell and Cochrane (1999), the model generates realistic time-varying volatility, skewness and kurtosis in fundamentals while still permitting closed-form solutions for asset prices.

Integration of a failure monitoring within a hybrid dynamic simulation environment [PDF]
, 2008 The complexity and the size of the industrial chemical processes induce the monitoring of a growing number of process variables. Their knowledge is generally based on the measurements of system variables and on the physico-chemical models of the process.

Decoherence induced by a dynamic spin environment (I): The universal regime [PDF]
, 2007 This article analyzes the decoherence induced on a single qubit by the interaction with a spin chain with nontrivial internal dynamics (XY-type interactions). The aim of the paper is to study the existence and properties of the so-called universal regime,
