Disease relevance of Markov Chains

 

High impact information on Markov Chains

  • The env V3 and p17gag regions of the genome were sequenced, and genetic distances were estimated by using the true tree and a nucleotide substitution model based on a general reversible Markov process with a gamma distribution to account for differences in substitution rates among sites [4].
  • A Bayesian model/variable selection approach using Markov Chain Monte Carlo computations was applied to these data, and serum CA125 values, to determine the best predictive model [5].
  • The relative intensities of the four methyl 13C peaks cannot be explained by the random process model for inclusion but are successfully reproduced by assuming the first-order Markov process, in which the inclusion probabilities of S and R depend on which enantiomer has precedingly entered the CA channel [6].
  • The first, second, third and fourth order Markov chain analysis on the amino-acid sequence of human dopamine beta-hydroxylase [7].
  • Interaction was coded with the Relational Control Coding System and analyzed as a Markov process [8].

Associations of Markov Chains with chemical compounds

  • Interaction sequences were coded with the Relational Control Coding System, and Markov process characteristics of order (degree of sequential dependency), stationarity, and role homogeneity were assessed with log-linear analysis [13].
  • Furthermore, Markov Chain Monte Carlo (MCMC) simulations of the posterior probability density provide uncertainties in all metabolic parameters from a single patient, thereby allowing comparisons in glucose metabolism from one individual to another [14].
  • The application allows the user to quantify word bias using Markov chain analysis and it allows the user to generate sliding window data for GC-skew, AT-skew, purine excess, keto excess and discrete word counts [15].
  • Using a Markov chain approach, Swedish cost data and a study period of 5 years, we conclude that H. pylori eradication with omeprazole and appropriate antibiotics is a cost-effective alternative compared with both maintenance and episodic treatment [16].
  • The approach is restricted to an analysis of purine and pyrimidine organization using the theory of stationary alternate Markov chains of first order [17].
