RNA molecules whose secondary structures contain similar substructures often have similar functions. Therefore, an important task in the study of RNA is to develop methods for discovering substructures in RNA secondary structures that occur frequently (also referred to as motifs). In this paper, we consider the problem of computing an optimal local(More)
In this paper we study a Lotka-Volterra predator-prey system with prey logistic growth under the telegraph noise. The telegraph noise switches at random two prey-predator models. The aim of this work is to determine the subset of omega-limit set of the system and show out the existence of a stationary distribution. We also focus on persistence of the(More)
The kinematic characteristic and energy of the conformations of a protein determine its motion and structure. Different conformations of the same protein have different amounts of energy. The protein favors the conformations whose energy levels are low because in that case, the conformations would be more stable. The energy level can be modelled as a(More)
