We modeled tracer injection through highly fractured media by Random Walk Particle Tracking simulations, and observed that production curves for different R values (distance between injection and production wells) are similar to each other and can be scaled. Hence, if we define P(t) as a...

The study of quenched random systems is facilitated by the idea that the ensemble averages describe the thermal averages for any specific realization of the couplings, provided that the system is large enough. Careful examination suggests that this idea might have a flaw, when the correlation...

The magnetic properties of a cylindrical Ising nanotube with a spin- 1/2 core surrounded by a spin- 3/2 shell system have been studied by means of the effective field theory (EFT). We have investigated the effects of crystal-field coupling at the surface shell and bilinear interactions among the...

With the aim of gaining insight into the notoriously difficult problem of energy and vorticity cascades in high dimensional incompressible flows, we take a simpler and very well understood low dimensional analog and approach it from a new perspective, using the Fourier transform. Specifically,...

Recent research has established log-periodic power law (LPPL) patterns prior to the detonation of the German stock index (DAX) bubble in 1998. The purpose of this article is to explore whether a Langevin equation extracted from real world data can generate synthetic time series with comparable...

It is argued that the process of perception takes origin within physics itself. A simple, physical model of a biological sensory receptor unit, a unit which mediates perception at its most elemental level, is developed. This model will be not just a detector of sensory signals (like a light...

The generalized dispersion relation for warm electrostatic waves in magnetized plasmas is derived in the context of the nonextensive q-distribution of Tsallis statistics. The dispersion relation is expressed as a function of different values of the nonextensive parameter q, which quantifies the...

We investigate the emergence of localized coherent behavior in systems consisting of two populations of social agents possessing a condition for non-interacting states, mutually coupled through global interaction fields. We employ two examples of such dynamics: (i) Axelrod’s model for social...

To simulate car-following behaviors better when the traffic light is red, three successive car-following data at a signalized intersection of Jinan in China were collected by using a new proposed data acquisition method and then analyzed to select input variables of the extended car-following...

In rotational symmetric gel sheets, we study the sheets with in-plane strain and deduce the equilibrium equations and the boundary conditions. The boundary is found to play an important role in the equilibrium configuration of the gel sheet. Compared to the sheet without a boundary, with a...
