Systems of branching, annihilating, and coalescing particles

and subject to annihilation, binary branching, coalescence, and deaths. In the case without annihilation, such systems have been studied in our 2005 paper ?Branching coalescing particle systems. The case with ...

Voter models with heterozygosity selection

This paper studies variations of the usual voter model that favour types that are locally less common. Such models are dual to certain systems of branching annihilating random walks that are parity preserving. For both the voter mod...

Measurement of the branching ratio related to the internal pair production of Y-90

the number of 511 keV photons originating from positron annihilation corrected for the annihilation of positrons in flight. Emission of annihilation photons was determined from. In both cases, the annihilation of ...

Duals and thinnings of some relatives of the contact process

This paper considers contact processes with additional voter model dynamics. For such models, results of Lloyd and Sudbury can be applied to find a self-duality, as well as dualities and thinning relations with systems of random walks with <...

Dynamics of excitable reactions in branched arrays of mass couppled reaction cells

as a cascade of several reaction cells with branched topology wherein an excitable reaction cell(s) and allowed to spread through the array. Due to the branched topology of the array, the waves can meet and interact. Upon interacti...

Common explanation of the behavior of some e+e- annihilation processes around sqrt s =1.9 GeV

We show that the behavior of the excitation curves of some e+ e- annihilation processes close to the nucleon-antinucleon threshold can be explained either by the rho(1900) resonance itself or by its interference with other resonance...

Characterization of lattice defects in metallic materials by positron annihilation spectroscopy: A review

on the atomic scale. Positron lifetime and Doppler broadening of annihilation photo-peak are the most common observables related to positron annihilation process. Positron lifetime, dislocations, grain boundaries etc. Posi...
