In the present Letter, we study in the framework of the Friedrichs model the evolution of a two-level system coupled to a continuum. This unitary evolution possesses a non-unitary component with a non-Hermitian effective ...

This study focuses on the potential of Pectobacterium carotovorum subsp. carotovorum (Pcc) strains

producing bacteriocin as a tool to control potato soft rot disease. Thirty out of 48 purified

bacterial strains ...

plant), various concentrations of aqueous extract and decay durations were employed as study factors under completely randomized design (CRD) with factorial arrangement by three replications in this study. The results indicated that germination...

We study the decay probability distribution and the survival probability of unstable quantum systems using an explicit formula of the spectral projections of the time operator in the statistical Liouville description for solvable Hamiltonians. We...

The quantum description of the unstable systems is investigated starting from the Schrödinger equation and using Hamiltonian describing discrete levels interacting with a continuum. This approach is applied to kaons decay processes by using a simple...

During visiting different greenhouses in Mahalat (Markazi province, Iran) in 2012-2013, bacterial soft rot

symptoms were observed on Opuntia and Haworthia spp. These consisted of small brown to black water-soaked ...
