The metropolitan melodramatics recall everything from The Wire to Chinatown (our intrepid bunny-fox double act are drawn into a vast political conspiracy) and turn on a city-wide panic over animals reverting to their predatory old selves.
The idea is to stop the animals reverting to repetitive, compulsive behaviours.
TNFα levels in experimental animals reverted to saline levels by 72 h (GD18), whereas IL-1β gene expression levels were still elevated, although this increase was not statistically significant.
Fraker and colleagues [ 40] reported that reduced food intake, decreased body weight gain, severe interstitial pneumonitis, periportal inflammation in the liver, and increases in the weights of the heart, lungs, kidney and spleen observed in TNF-α-treated animals reverted to normal levels when insulin was administered concurrently.
For most parameter values, the loss of immunity (R animals reverting to S) does not affect the number of secondary infections, but extreme parameter values (long-lived environmental contamination combined with a short period of immunity) may lead to more secondary infections.
Building on the SEIR model [ 8], we introduce two new aspects to the model: (i) a period of latency (L) in which animals are infected but not yet infectious and (ii) loss of immunity so that recovered (R) animals can revert back to susceptible.
As the animals slowly revert to their natural behaviors, the people watching remotely will learn both what those behaviors are and what kind of environment will best foster them.
The SIS model, in which animals can revert to susceptible state, fitted the data best (R2-value of 0.88, Table 4).
For paralyzers, the script calculates the latency to paralyze and several parameters that define the ability of individual animals to revert from paralysis to regular thrashing activity, including reversion probability (total time in reversion/total time after paralysis), time to first reversion, average reversion duration, and reversion strength (area under the curve during all reversion events).
