We present a one-parameter family of quantum maps whose spectral statistics are of the same intermediate type as observed in polygonal quantum billiards. Our central result is the evaluation of the spectral two-point correlation form factor at small argument, which in turn yields the asymptotic level compressibility for macroscopic correlation lengths.
natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen that would lower the heating value of natural ...
OBJECTIVE To explore triceps skinfold (TSF) compressibility and its associated factors among hospitalized patients. METHODS A cross-sectional study was conducted among hospitalized adult patients. Evolution of tissue compressibility during two seconds was registered and 120 TSF values were obtained using a digital calliper. Compressibility was determined according to the difference between th...
Modelling anisotropic adsorption-induced coal swelling and stress-dependent anisotropic permeability
To investigate the anisotropy of coal swelling, this study proposes an effective stress model for saturated, adsorptive fractured porous media by considering gas adsorption induced surface change on solid-fluid interface. The can be used to capture anisotropic swelling combining mechanical properties and link with permeability. Direction dependent fracture compressibility is describe evolution ...
Collective diffusion is investigated within the kinetic lattice gas model for systems of particles in one dimension with repulsive long-range interactions which are known to result in a staircaselike phase diagram with an infinite sequence of incompressible crystalline phases separated one from another by unstable compressible liquidlike phases. Using a recently proposed Gortel and Załuska-Kotu...
Thermodynamic properties of liquid bismuth under pressure: New regularities and an equation of state
A new regularity for internal pressure has been introduced based on the suggested potential energy function in liquid bismuth. Both experimental data and calculated quantities from power law equation of state have used to show validity regularity. The quantity X3Z−1 is a linear ln(X) with crossing points all isotherms at high temperature, where X=VVm0, V, Vm0, Z are molar volume, volume melting...
