Dynamically Optimized Sequential Experimentation (DOSE) for Estimating Economic Preference Parameters
No full textWe introduce DOSE—Dynamically Optimized Sequential Experimentation—to elicit preference parameters. DOSE starts with a model of preferences and a prior over the parameters of that model, then dynamically chooses a customized question sequence for each participant according to an experimenter-selected information criterion. After each question, the prior is updated, and the posterior is used to select the next, informationally-optimal, question. Simulations show that DOSE produces parameter estimates that are approximately twice as accurate as those from established elicitation methods. DOSE estimates of individual-level risk and time preferences are also more accurate, more stable over time, and faster to administer in a large representative, incentivized survey of the U.S. population (N = 2,000). By reducing measurement error, DOSE identifies a stronger relationship between risk aversion and cognitive ability than other elicitation techniques. DOSE thus provides a flexible procedure that facilitates the collection of incentivized preference measures in the field

century, with a special focus on the problem of transfering medical definitions into the colloquial language. In the next paragraph, the author presents results of her research and compares them with those made by Sławomira Sadowska in 2004, placing them in the context of general cultural changes in Poland, which concern the situation of disabled people
Enhanced lattice boltzmann modelling of axisymmetric flows
No full textAn enhanced axisymmetric Lattice Boltzmann fluid simulation model developed by the second author involves no calculation for velocity gradients and has the feature that all external force terms can simply be added to the model. In this paper, the model is extended and applied to investigate the characteristics of two complex axisymmetric flows for further assessment of its capability. First of all, Taylor-Couette flow for Newtonian and non-Newtonian fluids is considered. The combined effects of the Reynolds number, the radius ratio and the power-law index n on the flow characteristics are analysed for an annular space of finite aspect ratio. Different forced axisymmetric laminar coldflow jets are then taken into account with different values of forcing amplitudes in the jets. The numerical results are compared with existing numerical results and experimental data reported in the literature to demonstrate the accuracy of the model

Designing role-based view for object-relational databases
Full text linkIn a federated database system, a view mechanism is crucial since it is used to define exportable subsets of data ; to perform a virtual restructuring d ataset; and to construct the integrated schema. The view service in federated databa se systems must be capable of retaining as much semantic information as possible. The object-oriented ( 0 - 0 ) model was considered the suitable canonical data model since it meets the original criteria for canonical model selection. However, with the emergence of stronger object-relational (0 -R ) model, the re is a clear argument for using an 0 - R canonical model in the federation. Hence, research should now focus on th e development of semantically powerful view mechanism for th e newer model. Meanwhile, the availability of real 0 -R technologies offers researchers the opportunity to develop different forms of view mechanisms.
The concept of roles has been widely studied in 0 - 0 modelling and development. The role model represents some characteristics that the traditional 0-0 model lacked, such as object migration, multiple occurrences and context-dependent access. While many forms of 0-0 views were designed for the 0-0 canonical model, one option was to extend the 0-0 model to incorporate a role model. In a role model, the real entity is modelled in the form of a role rather than an object. An object represents the permanent properties of an entity is a root object; and an object represents the temporary properties of an entity is a role object.
The contribution of this research is to design a view system that employees the concept of roles for the 0 -R canonical model in a federated database system. In this thesis, an examination of the current 0 -R metamodel is provided first in order to provide an environment for recognising the roleview metadata and measuring the view performance; then a Roleview Definition Language (RDL) is introduced, along with the semantics for defining virtual classes and generating virtua l extents; finally, a working prototype is provided to prove th e role-based view system is implementable and the syntax is semantically correct
Sublytic complement C5b-9 complexes induce thrombospondin-1 production in rat glomerular mesangial cells via PI3-k/Akt: association with activation of latent transforming growth factor-beta1
No full textMesangial cell proliferation is a common cellular response to a variety of different types of glomerular injury. Complement C5b‐9 is a prime candidate to mediate mesangial cell proliferation, especially sublytic C5b‐9, which can induce the production of multiple inflammatory factors and cytokines. Transforming growth factor (TGF)‐β1 plays a major role in the accumulation of extracellular matrix (ECM), while thrombospondin (TSP)‐1 has been identified as an activator of latent TGF‐β1 in an in vitro system. Using rat glomerular mesangial cells (GMCs) as a model system, we assessed the effect of sublytic C5b‐9 on the expression of TSP‐1 and TGF‐β1 and explored the relevant pathway of signal transduction. First, we ensured the concentrations of anti‐Thy1 antibody and complement, which were regarded as a sublytic C5b‐9 dose, and examined whether the sublytic C5b‐9 induced expression of TSP‐1 in rat GMCs which, in turn, activated latent TGF‐β1 by real‐time polymerase chain reaction (PCR) and enzyme‐linked immunosorbent assay (ELISA), respectively. Then, we investigated the role of the PI3‐k/Akt pathway in sublytic C5b‐9‐induced TSP‐1 production in rat GMCs by Western blot analysis. The addition of sublytic C5b‐9 (5% anti‐Thy1 antibody and 4% normal serum) to rat GMCs induced activation of latent TGF‐β1 via TSP‐1. The addition of sublytic C5b‐9 apparently increased the protein of Akt phosphorylation, whereas PI3‐k inhibitor LY294002 could clearly reduce the increase of TSP‐1 induced by sublytic C5b‐9. These results indicate that TSP‐1 is an activator of latent TGF‐β1 in sublytic C5b‐9‐induced rat GMCs; furthermore, the PI3‐k/Akt signal transduction pathway may play a key role in sublytic C5b‐9‐induced TSP‐1 production
Supporting data for Temperature-dependent thermal conductivity of MBE-grown epitaxial SrSnO₃ films
No full textA single excel file containing all raw data for plots (outputs), including the main paper and the Supplementary Material, following the order of figure numbers. Archive of data included in .csv format.This work studies the temperature-dependent thermal properties of a single crystalline SSO thin film prepared with hybrid molecular beam epitaxy. By combining time-domain thermoreflectance and Debye–Callaway modeling, physical insight into thermal transport mechanisms is provided. At room temperature, the 350-nm SSO film has a thermal conductivity of 4.4 W m¯¹ K¯¹ , ∼60% lower than those of other perovskite oxides (SrTiO₃, BaSnO₃) with the same ABO₃ structural formula. This difference is attributed to the low zone-boundary frequency of SSO, resulting from its distorted orthorhombic structure with tilted octahedra. At high temperatures, the thermal conductivity of SSO decreases with temperature following a ∼T ¯⁰∙⁵⁴ dependence, weaker than the typical T¯¹ trend dominated by the Umklapp scattering.
