Broken ergodicity in myoglobin
… non-equilibrium states are examples of ""broken ergodicity"". Our experiments at low temperatures and high pressures prove the existence at short times are in broken ergodic states even at room temperature. These broken ergodic states give us a new mechanism for excited states to live long. The …

Ergodicity of Adaptive MCMC and its Applications
… weakest uniform drift conditions to ensure the ergodicity and WLLN of AMCMC. Further we answer the open problem 21 in Roberts and Rosenthal [48] through constructing a counter example and finding out some stronger condition which indicates the ergodic property of AMCMC. We find that the …

Stochastic hypodissipative hydrodynamic equations: well-posedness, stationary solutions and ergodicity
… /> 2. We also study stationary solutions and ergodicity of both anisotropic Navier–Stokes equations and Euler equations with positive damping terms on both the torus T<sup>*2*</sup> and the whole space ℝ<sup>*2*</sup>. We first show the existence of (H<sup>*1*</sup> -valued) martingale …

Product of random stochastic matrices and distributed averaging
… and it will be proven that it is necessary for ergodicity of any stochastic chain. This result will further be extended to ergodic classes, through the development of the concept of the infinite flow graph and $\ell_1$-approximation technique. For the converse implications, the product of …

Solidarity and ergodic properties of semi-Markov transition probabilities
… chapter the solidarity nature of geometric ergodicity within an irreducible class is examined, and necessary and sufficient conditions are derived for geometric ergodicity in the particular case of a process with a finite state space. In chapter three it is shown that the Laplace transforms …

Invariant measures for inner functions
… invariant, measures for inner functions, ergodicity and exactness will be discussed. Moreover, under some conditions, we prove that the restriction of an inner function to [Special characters omitted.] is ergodic if and only if the Julia set is the real line.

Probabilistic Methods In Information Theory
… of entropy theory, we study the concept of ergodicity, which helps us to further analyze the information of the system.</p>

Computer simulation and analysis of production line with two unreliable full batch machines and a finite buffer
… size on the production rate; the conditions of ergodicity; and the differences between the deterministic model and the exponential model are discussed.

ΑΣΥΜΠΤΩΤΙΚΗ ΘΕΩΡΙΑ ΜΗ ΟΜΟΓΕΝΩΝ ΜΑΡΚΟΒΙΑΝΩΝ ΣΥΣΤΗΜΑΤΩΝ
… SUCH AS STABILITY ASYMPTOTIC STABILITY AND WEAK ERGODICITY. IN THE LAST CHAPTER A SENSITIVITY ANALYSIS OF PROMOTION PARAMETERS IN A HIERARCHICAL SYSTEM IS PERFORMED WITH RESPECT TO CHANGES IN THE OTHER PARAMETERS OF THE SYSTEM.

Um modelo markoviano para simulação de vazões diárias
… prevailing that, for both cases, the chain ergodicity is determined and its stationary distribution is observed. A theoretic adjustment for markovian matrix lines is analysed through Pearson's indexes, drying out gama, normal and lognormal distributions. Dry and wet periods of the hydrologic …

Sampling Configurational Energy Landscapes
… systems due to a phenomenon known as broken ergodicity. This problem occurs when the energy barriers between different regions of the energy landscape make it difficult to sample both uniformly. In this work a novel superposition based approach that is embarrassingly parallel, based on the …

Three essays on econometrics
… correct numerical standard errors is geometric ergodicity of the MCMC chain. It is also shown that geometric ergodicity is satisfied under Metropolis Hastings chains with quasi-posterior for the whole class of extremum estimators. The third chapter considers fixed effects estimation and …

Uniform positive recurrence and long term behavior of Markov decision processes, with applications in sensor scheduling
… blanket stability, requiring only geometric ergodicity under the optimal policy. These results form the theoretical basis to apply the value iteration to classes of problems previously unavailable. We then consider a discrete-time linear system with Gaussian white noise and quadratic costs, …

High efficiency luminescent solar concentrator with interconnected gallium indium phosphide micro solar cells
… alternative designs that enhance waveguide ergodicity by geometry and scattering are proposed to improve LSC efficiency beyond what has been achieved. A model for identifying performance bottlenecks is also discussed. As MCRT results predict an optimal QD concentration that is not yet …

X-ray induced temperature dependent amorphous-amorphous transitions in the GeO2 glass
… of XPCS and IXS measurements allows the non-ergodicity factor and density fluctuations to be studied across a broad frequency range, providing new insight into the microscopic mechanisms governing irradiation-induced amorphous-amorphous transitions in oxide glasses.

Slice sampling on Riemannian manifolds
… on compact Riemannian manifolds we show uniform ergodicity with explicit constants for the geodesic slice sampler if the target distribution has a bounded density with respect to the Riemannian measure. As an important building block of this sampler, we provide an explicit expression for the …
