Stability Analysis of a Slurry Trench in Cohesive-Frictional Soils
Open Geosciences, 2019 The slurry trench has become increasingly common in underground engineering and the stability of a slurry trench has been an important design issue. Although many studies have focused on the overall stability of a slurry trench, few of that are related ...

Dynamical Analysis and Solutions of Nonlinear Difference Equations of Thirty Order
Universal Journal of Mathematics and ApplicationsDiscrete-time systems are sometimes used to explain natural phenomena that happen in nonlinear sciences. We study the periodicity, boundedness, oscillation, stability, and certain exact solutions of nonlinear difference equations in this paper. Using the

Mathematical modelling and analysis of stochastic malaria and COVID-19 co-infection model
Applied Mathematics in Science and EngineeringIn this article, we construct and analyse a stochastic mathematical model to study the co-infection dynamics of malaria and COVID-19 in a population. We derive the basic reproduction number associated with the disease-free equilibrium of the stochastic ...

A short proof of stability of topological order under local perturbations
, 2010 Recently, the stability of certain topological phases of matter under weak perturbations was proven. Here, we present a short, alternate proof of the same result. We consider models of topological quantum order for which the unperturbed Hamiltonian $H_0$

The impact of obesity on chronic diseases: type 2 diabetes, heart disease, and high blood pressure
Applied Mathematics in Science and EngineeringObesity is a risk factor for several chronic diseases, including type 2 diabetes, heart disease, and high blood pressure. Developing models of obesity and its complications allows for close monitoring of these epidemics, informing the creation of ...

Local stability of an open-access anchovy fishery model [PDF]
Computational Ecology and Software, 2015 In this paper, we study the qualitative behavior of following open-access anchovy fishery model: xn+1=axnb-d α xvnyn, yn+1=yn(η(pαxvn-c)+1), where a,b,c,d,v,p,α, η, and the initial conditions x0, y0 are positive real numbers.

Groups, Geometry, and DynamicsWe introduce a notion of “local stability in permutations” for finitely generated groups. If a group is sofic and locally stable in our sense, then it is also locally embeddable into finite groups. Our notion is weaker than the “permutation stability” introduced by Glebsky–Rivera and Arzhantseva–Paunescu, which allows one to upgrade soficity to ...
