    © 2015 American Chemical Society.Near-infrared dye-sensitized upconversion nanoparticles can broaden the absorption range and boost upconversion efficiency of UCNPs. Here, we achieved significantly enhanced upconversion luminescence in dye-sensitized core/active shell UCNPs via the doping of ytterbium ions in the UCNP shell, which bridged the energy transfer from the dye to the UCNP core. As a result, we synergized the two most practical upconversion booster effectors to amplify upconversion eff…Read more

    © 2016, American Society for Biochemistry and Molecular Biology Inc. All rights reserved.Glycyl-tRNA synthetase is the enzyme that covalently links glycine to cognate tRNA for translation. It is of great research interest because of its nonconserved quaternary structures, unique species-specific aminoacylation properties, and noncanonical functions in neurological diseases, but none of these is fully understood. We report two crystal structures of human GlyRS variants, in the free form and in co…Read more

    © 2014 Elsevier B.V.. Nitrogen pollution is a global environmental problem that has greatly increased the risks of both the eutrophication of surface waters and contamination of ground waters. The majority of N pollution mainly comes from agricultural fields, in particular during rice growing seasons. In recent years, a gradual shift from the transplanting rice cultivation method to the direct seeding method has occurred, which results in different water and N losses from paddy fields and leads …Read more

    In the recent decade, increasing costs of labor, water, and fertilizers around the world led to a change in the method of crop establishment from traditional transplanted rice to direct-seeded rice and to a substantial rise in the DSR-managed area. Since water management in areas with DSR is quite different from those with TPR, vertical water movement and water and nutrient losses during the crop season may be different as well. Water flow and water losses in a DSR field in the Taihu Lake Basin …Read more

    Marketing modeling reality and the realities of marketing modeling
    with A. T. Coughlan, S. C. Choi, W. Chu, C. A. Ingene, S. Moorthy, V. Padmanabhan, J. S. Raju, and R. da SobermanStaelin
    This paper shows how analytic modeling research in the Marketing field is focused on answering questions of "How?" and "Why?" It describes the disciplines involved in analytic modeling; examines how the key criteria of parsimony and robustness help to define a good model; and discusses other goodness criteria, including appropriate use of analytic techniques, applicability of the model to institutionally rich, real-world problems, non-obvious results, generalizability, and ability to provide ins…Read more

    The Imparity of the Parity Principle
    Philosophia 49 (5): 2265-2273. 2021.
    Some recent authors suggest that the extended view fails because it does not follow from functionalism. For although functionalism can tell us whether a system is cognitive, it does not show whether such a newly identified cognitive system can be attributed to the very same subject. I argue that Clark and Chalmers can dodge this attack by claiming that the Parity Principle is essentially an analogy. In their crucial thought experiment, it can be argued that Otto’s notebook is similar to Inga’s b…Read more
