We present exact calculations of the partition function for the q-state Potts model for general q, temperature and magnetic field on strips of the square lattices of width Ly = 2 and arbitrary length Lx = m with periodic longitudinal boundary conditions. A new representation of the transfer matrix for the q-state Potts model is introduced which can be used to calculate the determinant of the tr...

Wepresent an analytically tractable dynamic stochastic general equilibrium model that incorporates micro-level fixed and convex adjustment costs. We provide an explicit characterization of equilibrium dynamics by a system of nonlinear stochastic difference equations. We provide general conditions under which our model features investment lumpiness at the microeconomic level, but aggregate dynam...

Cross-cultural studies suggest that access to a conventional language containing words that can be used for counting is essential to develop representations of large exact numbers. However, cultures that lack a conventional counting system typically differ from cultures that have such systems, not only in language but also in many other ways. As a result, it is difficult to isolate the effects ...

We define a block observable for the q-state Potts model which exhibits an intermittent behaviour at the critical point. We express the intermittency indices of the normalised moments in terms of the magnetic critical exponent β/ν of the model. We confirm this relation by a numerical similation of the q = 2 (Ising) and q = 3 two-dimensional Potts model. LPTB 93-2 Mars 1993 PACS 05.70.Jk 64.60.F...

Q fever, a worldwide zoonosis caused by Coxiella burnetii, has many manifestations in humans. Endocarditis is the most serious complication of Q fever. Animal models are limited to acute pulmonary or hepatic disease and reproductive disorders. An appropriate experimental animal model for Q fever endocarditis does not yet exist. In this study, severe combined immunodeficient (SCID) mice infected...

This paper develops a Tobin’s q model of house prices which shows that changes in interest rates, demography, and income are likely to have only temporary effects on house prices while house prices in the long run are determined by prices of developed land, value added taxes, stamp duties, and construction costs. Empirical estimates show that agricultural land prices are a proxy for urban land ...

Objective. To assess the sources of variability associated with an EMG-assisted model of spine loading. Design. In vivo measurements of trunk dynamics, lifting moments and muscle activities were used as inputs into an EMG-assisted spine loading model. Background. Several types of variability are inherent in biomechanical assessments of risk associated with trunk bending motions during lifting. ...

PMS has existed at least since the beginning of medical writing, and is estimated to affect large proportions of women worldwide. But the etiology remains unknown, diagnostic definition and methods vary tremendously, and treatment is wholly symptom-oriented. This poor state of understanding has been attributed to a lack of theoretical perspective. The current work provides such a theoretical pe...
