We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a point mass. We investigate the effect of such a Yukawa-like term on the dynamics of self-gravitating disks. More specifically, we investigate the consequences of the presence of this term for the local stability of t...

Common to all life on Earth are the mechanisms of genetic encoding, in which specific trinucleotide sequences in DNA and RNA map to specific amino acids in synthesized proteins. The proteins which catalyse the coding are themselves products of that synthesis, posing the question of how the system bootstrapped itself and how it maintains stability. Mechanistic models based on chemical associatio...

This paper introduces a methodology for soil slope stability analysis based on optimization, limit equilibrium principles and method of slices. In this study, the slope stability analysis problem is transformed into a constrained nonlinear optimization problem. To solve that, a Self-Adaptive Genetic Algorithm (GA) is utilized. In this study, the slope stability safety factors are the objective ...
