Manganese oxides occur naturally as minerals in at least 30 different crystal structures, providing a rigorous test system to explore the significance of atomic positions on the catalytic efficiency of water oxidation. In this study, we chose to systematically compare eight synthetic oxide structures containing Mn(III) and Mn(IV) only, with particular(More)
In this paper we describe our participation in the 2015 BioASQ challenge task on question answering (Phase A). Participants need to respond to the natural language questions in the format of documents, snippets, concepts and RDF triplets. In document retrieval, we build a generic retrieval model based on the sequential dependence model, Word Embedding and(More)
Incubation systems were established to investigate the effects of quercetin, kaempferol, isoquercitrin and astragalin in Lysimachia clethroides Duby on the activities of CYP2E1 and CYP3A4 in rat liver microsomes in vitro. Probe substrates of 4-nitrophenol and testosterone as well as flavonoids at different concentrations were added to the incubation(More)
In this paper, we describe our participation in the INEX 2015 Social Book Search(SBS) Track Suggestion Task. We try out all possible groups of XML fields to find out the most effective group for relevance feedback model. We investigate the contribution of user-generated data and construct a social book search system based on several important techniques.(More)
In this paper, we study adaptive finite element discretisation schemes for a class of parameter estimation problem. We propose to use adaptive multi-meshes in developing efficient algorithms for the estimation problem. We derive equivalent a posteriori error estimators for both the state and the control approximation, which particularly suit an adaptive(More)
