PARAMETER EVOLUTION IN THE θ-MODEL

Confinement, Supersymmetry Breaking and θ Parameter Dependence in the Seiberg-Witten Model

By using the standard perturbation theory we study the mass as well as θ parameter dependence of the Seiberg-Witten theory with SU(2) gauge group, supplemented with a N = 1 supersymmetric as well as a smaller nonsupersymmetric gaugino mass. Confinement persists at all values of the bare vacuum parameter θph; as it is varied there is however a phase transition at θph = −π, π, 3π, . . .. At these...

Molecular Evolution of the Primate α-/θ-Defensin Multigene Family

The primate α-/θ-defensin multigene family encodes versatile endogenous cationic and amphipathic peptides that have broad-spectrum antibacterial, antifungal and antiviral activity. Although previous studies have reported that α-/θ-defensin (DEFA/DEFT) genes are under birth-and-death evolution with frequent duplication and rapid evolution, the phylogenetic relationships of the primate DEFA/DEFT ...

Θ ∗ partner to the Θ ( 1540 ) baryon

If the exotic baryon Θ(1540) is udud¯ s with J P = 1 2 + , we predict that there is a Θ * (1540− 1680) with J P = 3 2 +. The width Γ(Θ * → KN) is at least a factor of three larger than Γ(Θ). The possibilities of Θ * → KN π or Θγ via M 1 and E2 multipoles are discussed. A major plank in establishing the constituent quark model was the absence of baryons with strangeness +1. The announcement of s...

On (θ, θ)-Derivations in Semiprime Rings

Online State Space Model Parameter Estimation in Synchronous Machines

The purpose of this paper is to present a new approach based on the Least Squares Error method for estimating the unknown parameters of the nonlinear 3rd order synchronous generator model. The proposed method uses the mathematical relationships between the machine parameters and on-line input/output measurements to estimate the parameters of the nonlinear state space model. The field voltage is...
