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)
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)
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)
The degradation of caffeic acid under ultrasound treatment in a model system was investigated. The type of solvent and temperature were important factors in determining the outcome of the degradation reactions. Liquid height, ultrasonic intensity and duty cycle only affected degradation rate, but did not change the nature of the degradation. The degradation(More)
Bullacta exarata is one of the most economically important aquatic species in China, noted for not only its delicious taste and nutritional value, but also for its pharmacological activities. In order to explore its potential in medical applications, a mannoglucan designated as BEPS-IB was isolated and purified from the foot muscle of B. exarata after(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)
