The Stochastic Collection and Replenishment (SCAR) scenario is motivated by mining and agricultural scenarios where a dedicated replenishment agent transports a resource between a centralised replenishment point to agents using the resource in the field.
Existing research has typically approached the problem of scheduling the actions of the dedicated replenishment agent from a short-term and deterministic angle.
The agents in the field typically operate within fixed areas (for example, benches in mining applications, and fields or orchards in agricultural scenarios), and the motion of the replenishment agent may be restricted by a road network.
For the CEUS protocol a destruction-replenishment method was used to calculate the time for 80% replenishment of Definity contrast agent, whilst in DCE-MRI the total time to achieve 80% uptake of Magnevist gadolinium contrast agent was found.
After clearance of microbubbles, the replenishment of the contrast agent in the allograft and the changes in echogenicity can be followed and evaluated in a predefined region of interest (ROI).
These results suggest that the comparatively low level of hexamer-to-trimer conversion in conditioned media is due to the lack of replenishment of the limiting agent(s) secreted by cells.
Extensive numerical experiments suggest that ignoring the possible influence of the agent on the replenishment leadtime can be costly, but that the cost penalty of ignoring agency can be significantly reduced by a simple contract.
Its disruption with depolymerising agents would therefore facilitate vesicle replenishment of the release sites, as shown in a large variety of secretory cells (Malacombe et al., 2006), by increasing the number of available vesicles for docking and priming.
The sentence has been modified (now in the Results and Discussion, fourth paragraph) to read: 'Its disruption with depolymerising agents would therefore facilitate vesicle replenishment of the release sites, as shown in a large variety of secretory cells (Malacombe et al., 2006), by increasing the number of available vesicles for docking and priming.
The mTT is a measure of the time to replenishment after flash destruction of the contrast agent (it decreases with higher levels of perfusion).
