Recent experimental results show a large enhancement of the 2π emission on the scalar isoscalar channel, which had been predicted by some theoretical estimates. We present here a detailed calculation of the A(π, 2π)X process incorporating a microscopic model for the elementary reaction in vacuum, pion-pion final state interaction in the nuclear medium, and other nuclear medium effects.

We propose a combined spatial and non-spatial probabilistic modeling methodology motivated by an inspection task performed by a group of miniature robots. Our models explicitly consider spatiality and yield accurate predictions on system performance. An agent’s spatial distribution over time is modeled by the Fokker–Planck diffusion model and complements current non-spatial microscopic and macr...

Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of complicated traffic facilities and Intelligent Trans...

s2 1 1d-dimensional anti–de Sitter (AdS) gravity is quantized in the presence of an external scalar field. We find that the coupling between the scalar field and gravity is equivalently described by a perturbed conformal field theory at the boundary of AdS3. This allows us to perform a microscopic computation of the transition rates between black hole states due to absorption and induced emissi...

The number of scintillons, which are cellular organelles responsible for light emission in the marine alga Gonyaulax, were counted by both immunofluorescence and electron microscopic methods and found to vary tenfold between subjective day and subjective night. The number of scintillons peaks during the subjective night, as does stimulated bioluminescence (flashing). Furthermore, the number dro...
