objective: the present study compares the efficacy of two most commonly used biofeedback relaxation techniques in the treatment of generalized anxiety disorder. method: 45 individuals with generalized anxiety disorder were randomly assigned to three groups (n=15): group i received electromyographic biofeedback relaxation training, group ii received alpha-electroencephalographic biofeedback rela...

We consider a new problem of designing network with small s - t effective resistance. In this problem, we are given an undirected graph G = (V,E) , two designated vertices s,t ∈ V and budget k . The goal is to choose subgraph at most edges minimize the This interpolation between shortest path minimum cost flow has applications in electrical design. present several algorithmic hardness results f...

In this study, Polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (I-V) characteristics are numerically investigated. Using a tight-binding Hamiltonian model, the methods based on Non-equilibrium Green’s function theory, Landauer formalism and Newns-Anderson model, our calcu...
