Steady-State Mean-Square Deviation Analysis of the Zero-Attracting CLMS Algorithm With Circular Gaussian Input [PDF]
IEEE Access, 2019 When the complex least mean-square (CLMS) algorithm is used to estimate a complex sparse system, its convergence rate is relatively slow. To make full use of the sparsity of the unknown system to improve convergence rate, a zero-attracting CLMS (ZA-CLMS)

Nonequilibrium chemical potentials of steady-state lattice gas models in contact: A large-deviation approach [PDF]
Physical Review E, 2019 We introduce a general framework to describe the stationary state of two driven systems exchanging particles or mass through a contact, in a slow exchange limit. The definition of chemical potentials for the systems in contact requires that the large-deviations function describing the repartition of mass between the two systems is additive, in the ...

Fluctuation theorems and large-deviation functions in systems not featuring a steady state [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2020 Motivated by the time behavior of the functional arising in the variational approach to the KPZ equation, we have adapted a path-integral scheme to deal with unstable systems. In a simple mesoscopic model and under two scenarios, we define a suitable mean value of (the exponential of) the entropy production between arbitrary initial and final states ...

Oxidation photochemistry in the Southern Atlantic boundary layer: unexpected deviations of photochemical steady state [PDF]
Atmospheric Chemistry and Physics, 2011 Abstract. Ozone (O3) is a photochemical oxidant, an air pollutant and a greenhouse gas. As the main precursor of the hydroxyl radical (OH) it strongly affects the oxidation power of the atmosphere. The remote marine boundary layer (MBL) is considered an important region in terms of chemical O3 loss; however surface-based atmospheric observations are ...

Deviations of cup anemometer rotational speed measurements due to steady state harmonic accelerations of the rotor [PDF]
Measurement, 2016 The measurement deviations of cup anemometers are studied by analyzing the rotational speed of the rotor at steady state (constant wind speed). The differences of the measured rotational speed with respect to the averaged one based on complete turns of the rotor are produced by the harmonic terms of the rotational speed. Cup anemometer sampling periods

Deviations from the Steady-State in Ion Transfer through Perm-selective Membranes [PDF]
Nature, 1961 DURING experiments on polarization phenomena of perm-selective membranes, results were obtained which were inconsistent with the generally accepted idea that during the transfer of ions through such membranes by means of a constant direct current, a steady state is established under given experimental conditions1.

Annales de l'Institut Henri Poincaré, Probabilités et StatistiquesConsider the symmetric exclusion process evolving on an interval and weakly interacting at the end-points with reservoirs. Denote by $I_{[0,T]} (\cdot)$ its dynamical large deviations functional and by $V(\cdot)$ the associated quasi-potential, defined as $V( ) = \inf_{T>0} \inf_u I_{[0,T]} (u)$, where the infimum is carried over all trajectories ...

Large deviations of density in the non-equilibrium steady state of boundary-driven diffusive systems [PDF]
A diffusive system coupled to unequal boundary reservoirs eventually reaches a non-equilibrium steady state. While the full-counting-statistics of current in these non-equilibrium states are well understood for generic systems, results for steady-state density fluctuations remain limited to a few integrable models. By employing an exact solution of the
