Streaming potential is a passive hydrogeophysical method that can be used to monitor water flow in porous media. However, quantitative use of this requires good understanding the streaming generation saturated In work, we Critical Path Analysis (CPA) propose new model estimate coupling coefficient (SPCC) By comparing proposed with 109 experimental data points for both unconsolidated samples suc...

The (2+1) dimensional gauged O(3) nonlinear sigma model with Chern-Simons term is canonically quantized. Furthermore, we study a nonminimal coupling in this model implemented by means of a Pauli-type term. It is shown that the set of constraints of the model is modified by the introduction of the Pauli coupling. Moreover, we found that the quantum commutator relations in the nominimal case is i...

I derive conservative upper bounds on the supersymmetry breaking parameter m1/2 as a function of the strong coupling in the Standard Supersymmetric Model (SSM) using gauge coupling unification. I find that over more than 99% of the parameter space, α3 > 0.120 implies that m1/2 is below 10TeV and α3 > 0.129 implies that m1/2 is below 1TeV. I express the variation of these bounds over the SSM par...

Concerning the fluctuation which is observed in biological sensory systems and cortical neuronal networks, the roles of fluctuations in pulsed neural networks are investigated. As a model of a single neuron, the FitzHugh-Nagumo model is used, and two kinds of couplings of neurons are considered, namely, the electrical coupling which is often observed in sensory systems, and the chemical couplin...

SUMMARY Seismoelectric signals are generated by electrokinetic coupling from seismic wave propagation in fluid-filled porous media. This process is directly related to the existence of an electrical double layer at interface between pore fluid and minerals composing walls. The seismoelectric method attracts interest researchers different areas, oil gas reservoir characterization hydrogeophysics...

Large black holes in an asymptotically AdS spacetime have a dual description in terms of approximately thermal states in the boundary CFT. The reflecting boundary conditions of AdS prevent such black holes from evaporating completely. On the other hand, the formulation of the information paradox becomes more stringent when a black hole is allowed to evaporate. In order to address the informatio...

Unruh [1] demonstrated that black holes have an analogy in acoustics. Under this analogy the acoustic event horizon is defined by the set of points in which the local background flow exceeds the local sound speed. In past work [2], we demonstrated that under a white noise source, the acoustic event horizon will radiate at a thermal spectrum via a classical tunneling process. In this work, I sum...
