Abstract

fetched live from OpenAlex

In this paper, we propose and analyze a delayed diffusive viral dynamic model incorporating cell-mediated immunity and both cell-free and cell-to-cell transmission. After discussing the well-posedness, we provide some preliminary results on solutions. Then we study the existence and uniqueness of homogeneous steady states, which turned out to be completely determined by the basic reproduction number of infection <i>R</i><sub>0</sub> and the basic reproduction number of immunity <i>R</i><sub>1</sub>. Note that when <i>R</i><sub>1</sub> is defined, it is necessary that <i>R</i><sub>0</sub> &gt; 1. The main result is a threefold dynamics. Roughly speaking, when <i>R</i><sub>0</sub> &lt; 1 the infection-free steady state is globally asymptotically stable; when <i>R</i><sub>1</sub> ≤ 1 &lt; <i>R</i><sub>0</sub> the immunity-free infected steady state is globally asymptotically stable; when <i>R</i><sub>1</sub> &gt; 1 the infected-immune steady state is globally asymptotically stable. The approaches are linearization technique and the Lyapunov functional method. The theoretical results are also illustrated with numerical simulations.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
