Abstract: A method and a system for setting health monitoring warning thresholds of long-span arch bridges based on reliability criteria are provided. The method includes establishing a performance function based on structural ultimate responses and warning thresholds of the long-span arch bridge; determining target reliability indices, setting initial values of random variables and warning thresholds, and defining convergence tolerance errors; calculating gradient values of the performance function, computing scaling factors based on the gradient values, obtaining failure points of the performance function through the scaling factors combined with a conjugate search strategy, and updating warning thresholds at the failure points; iterating until errors become less than or equal to the convergence tolerance errors to establish reliability criteria for warning threshold configuration; and deriving warning thresholds corresponding to target reliability indices according to the reliability criteria.

Abstract: A reagent for extracting immunosuppressant drugs from a whole blood sample for immunoassay includes protein denaturant, proteolytic enzyme, surfactant and pH buffer. A method and an immunoassay kit for detection of the immunosuppressant concentration in a whole blood sample uses the extraction reagent. The extraction reagent doesn't need the use of organic solvent as that in the traditional extraction methods, therefore the adverse effects of the organic solvent on the antibody activity in a detection system and the other relative defects associated to its use are obviated. The drug extraction process doesn't need centrifugation, as the processed sample can be directly applied for immunoassay. The operation for drug extraction is simple, and the detection result based on this extraction method is accurate.

Abstract: A method for growing a crystal boule includes the steps of: periodically pulling upwardly a seed crystal dipped into a melt in a crucible to grow a first neck of the crystal boule below the seed crystal; and continuously pulling upwardly the seed crystal and the first neck of the crystal boule to grow a second neck of the crystal boule below the first neck.
