Stability analysis of a model for HIV infection with RTI and three intracellular delays.
TL;DR: The stability of the steady states is analyzed and a threshold value for the first delay at which the system exhibits a Hopf bifurcation is determined, which might explain the clinically observed transient elevated viremia called viral blips.

A model of HIV-1 infection with HAART therapy and intracellular delays
Rachid Ouifki,Gareth Witten +1 more
TL;DR: A model of HIV-1 infection with triple drug therapy with three delays and the incorporation of these delays improves the critical efficacy of the treatment, and destabilizes the infected steady state or leads to an infected steadyState with more healthy cells and less infected cells and viruses.

Designing a Mathematics Course for Chemistry and Geology Students.
TL;DR: In this article, the design of a one-semester second year mathematics course, mainly for chemistry and geology students, was described, with three specific objectives: to develop students' ability to quantitatively analyse problems arising in their own field, to illustrate the great utility of mathematical models to provide answers to key chemistry and Geology problems, to develop student's appreciation of the diversity of mathematical approaches potentially useful in the chemical and geological sciences.

Optimal Bespoke CDO Design via NSGA-II
TL;DR: This research concludes that CDO tranche returns at all levels of risk under the Clayton copula assumption performed better than the sub-optimal Gaussian assumption.

Modelling the control of energy partitioning during sub-maintenance feeding in cattle
TL;DR: In this paper, a simulation model was developed to examine the effect that a constant input of energy at four different levels had on the concentration of blood metabolites and the partition of energy in intermediary metabolism.
