Global stability in large economies

open access: hybridEconomic Theory Bulletin, 2023
Abstract A result is obtained showing how global stability of equilibrium, under the standard tâtonnement dynamic, arises in large economies having a continuous, diffuse distribution of consumers, as well as many goods.

The effect of PrEP uptake and adherence on the spread of HIV in the presence of casual and long-term partnerships

open access: yesMathematical Biosciences and Engineering, 2022
A model with both casual and long-term partnerships is considered with respect to the impact of a pre-exposure prophylaxis (PrEP) on the spread of HIV. We consider the effect of the effectiveness of PrEP, the rate that susceptible individuals choose to ...

Dynamic analysis of a cytokine-enhanced viral infection model with infection age

open access: yesMathematical Biosciences and Engineering, 2023
Recent studies reveal that pyroptosis is associated with the release of inflammatory cytokines which can attract more target cells to be infected. In this paper, a novel age-structured virus infection model incorporating cytokine-enhanced infection is ...

The Global Stability of M33 in MOND [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract The dynamical stability of disk galaxies is sensitive to whether their anomalous rotation curves are caused by dark matter halos or Milgromian dynamics (MOND). We investigate this by setting up a MOND model of M33. We first simulate it in isolation for 6 Gyr, starting from an initial good match to the rotation curve (RC).

Global stability analysis and stabilization of power amplifiers [PDF]

open access: yes2008 Microwaves, Radar and Remote Sensing Symposium, 2008
Power amplifiers often exhibit undesired behavior from certain input power value which cannot be predicted with a small-signal stability analysis. Among the commonly observed undesired phenomena are spurious oscillations, frequency divisions, hysteresis or chaos.
