let x be a random variable from a normal distribution with unknown mean θ and known variance σ2. in many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. as the usual estimator of θ, i.e., x under the linex loss function is inadmissible, finding some competitors for x becomes worthwhile. the only study in the literature considered the problem of min...

The high-dimensional search space involved in markerless full-body articulated human motion tracking from multiple-views video sequences has led to a number of solutions based on metaheuristics, the most recent form of which is Particle Swarm Optimization (PSO). However, the classical PSO suffers from premature convergence and it is trapped easily into local optima, significantly affecting the ...

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...
