Abstract. We derive critical noise levels for Gallager codes on asymmetric channels as a function of the input bias and the temperature. Using a statistical mechanics approach we study the space of codewords and the entropy in the various decoding regimes. We further discuss the relation of the convergence of the message passing algorithm with the endogenous property and complexity, characteriz...

A growing body of evidence indicates bilateral but asymmetric hemispheric involvement in speech perception. We used magnetoencephalography to record neuromagnetic evoked responses in 10 adults to consonant-vowel syllables that differ in a single phonetic feature, place of articulation. We report differential activation patterns in M100 latency, with larger differences in the right hemisphere th...

We show that a number of problems of modern cosmology may be addressed and solved in the framework of multidimensional gravity with high-order curvature invariants, without invoking other fields. As applications of this approach, we mention primordial inflation and particle production after it; description of the modern accelerated stage of the Universe with stable compact extra dimensions; con...

this work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. the analysis is presented through an extended lagrangian hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. the complete dynamics of asymmetries of rotor system is investigated with a case study. in this work, a mathematical model is ...

BACKGROUND For the past few years, treatment of contusions and associated symptoms, such as bruising, pain, and loss of function, has involved instrument-based therapies, ie, lasers, electromagnetic fields, and electrical stimulation. In this study, tissue optimization (TO) sessions were applied using a radioelectric asymmetric conveyor (REAC) for the treatment of contusions and associated symp...

this paper investigates asymmetric behaviors of income inequality and consumption expenditures inequalities, the relationships between them and sketches their trends in the iranian households’ survey for the period of 1979 to 2006. for this purpose, and to analyze the relationships between variables panel data methodology was employed. results indicate that all the fluctuations of income inequa...

This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...

credence goods market is one of the markets that the asymmetric information has transformed it to a missing market. those goods and services that the applicant cannot determine the exact amount of their expenses due to the asymmetric information are called credence goods. from the economists' perspective, transaction in a market where participants are ignorant about each other is a game wi...

The physical processes in the damping system of salient-pole synchronous machine rotor, which cause gradual destruction its structure, have been studied. In particular, distributions currents, temperatures and thermomechanical stresses rods during operation asynchronous asymmetric modes operation, as well case rotor eccentricity. A field mathematical model has developed that takes into account ...
