We restudy the phase diagram of the 2D-Ising model with competing interactions J<Subscript>1</Subscript> on nearest neighbour and J<Subscript>2</Subscript> on next-nearest neighbour bonds via Monte-Carlo simulations. We present the finite temperature phase diagram and introduce computational methods which allow us to calculate transition...</subscript></subscript>

An analysis of minute-tick data from the Japanese stock index market is reported for a three-year period of 2000/7/4–2003/6/30. Correlation patterns and principal component distributions were determined for 180 constituents of the NIKKEI 225 index, excluding the effects of after-hours trading...

The paper deals with the development of a theory for describing two-dimensional (2D) random lattice networks of resistors with a particular topology. We consider a 2D anisotropic random lattice where each node of the network is connected to a reference node (substrate) through a given random...

In this work, electrical measurements were performed on a polymer-dispersed LC sample so that we could demonstrate the temperature dependent molecular behavior, determined according to the electrical response of the system. Experimental results are found to be in favorable accordance with the...

We consider the Euclidean D-dimensional -λ|ϕ |<Superscript>4</Superscript>+η|ϕ|<Superscript>6</Superscript> (λ,η0) model with d (d ≤ D) compactified dimensions. Introducing temperature by means of the Ginzburg–Landau prescription in the mass term of the Hamiltonian, this model can be interpreted as describing a first-order phase...</superscript></superscript>
