In this paper we explore a principled, integrated approach to the process of creating complex planning applications and introduce and evaluate a new hybrid task-reduction planner called HyHTN. In the short term our work is leading to an experimental research platform for investigating the synergy of integrated tools. The approach is centred around the use(More)
We have demonstrated the neuroprotection of hydrogen sulfide (H2S) against chemical hypoxia-induced injury by inhibiting p38MAPK pathway. The present study attempts to evaluate the effect of H2S on chemical hypoxia-induced inflammation responses and its mechanisms in PC12 cells. We found that treatment of PC12 cells with cobalt chloride (CoCl2, a hypoxia(More)
In this paper we discuss and describe preliminary results of integrating two strands of planning research-that of using plan graphs to speed up planning, and that of using object representations to better represent planning domain models. To this end we have designed and implemented OCL-graph, a plan generator which builds and searches an object-centred(More)
Hydrogen sulfide (H2S) protects cardiomyoblasts against high glucose (HG)-induced injury by inhibiting the activation of p38 mitogen-activated protein kinase (MAPK). This study aims to determine whether the leptin–p38 MAPK pathway is involved in HG-induced injury and whether exogenous H2S prevents the HG-induced insult through inhibition of the leptin–p38(More)
Recent successful applications of AI planning technology have highlighted the knowledge engineering of planning domain models as an important research area. We describe a prototype implementation of a translation algorithm between two languages used in planning representation: PDDL, a language used for communication of example domains between research(More)
