Wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. To remove this problem, prediction of wax disappearance temperature (WDT) seems necessary. In this study, the pressure influence on the wax disappearance temperatu...

Self-consistent dynamics of the multi-component, N -field quintessence and gravity is formulated as relativistic N -body dynamics, embedded in a static viscous flat space and under the forces given by the interacting Lorentz scalar potential via exchanges of field bosons. The Ratra-Peebles power-law potential of effective single-field quintessence can be derived from this ”microscopic” perspect...

We use resurgent analysis to study non-perturbative aspects of the one-dimensional, multicomponent Hubbard model with an attractive interaction and arbitrary filling. In two-component case, we show that leading Borel singularity perturbative series for ground-state energy is determined by gap, as expected superconducting systems. This turns out be renormalon type, identify a class diagrams corr...

We examine how the location of weak electrical coupling affects phase-locking in a pair of model fast-spiking interneurons. Each model neuron consists of a somatic compartment and a passive dendritic compartment. At relatively low frequencies, the phase-locking structure for somatic and dendritic coupling is qualitatively the same: below a critical frequency, stable synchronous and anti-phase a...
