In a spatial data analysis problem, usually we build a hierarchical model with spatial structure described though random effects using a Gaussian process. If the sample size is very large, exact likelihood based inference becomes unstable and, eventually, infeasible since it involves computing quadratic forms and determinants associate with a large(More)
We tackle the problem of maintaining materialized top-k views in this paper. Top-k queries, including MIN and MAX as important special cases, occur frequently in common database workloads. A top-k view can be materialized to improve query performance, but in general it is not self-maintainable unless it contains all tuples in the base table. Deletions and(More)
NGAL is a promising novel biomarker for acute kidney injury (AKI) and chronic kidney disease (CKD). More rapid and user-friendly methods are needed for the timely monitoring of NGAL in human urine and serum. UCP technology-based lateral flow assay (UPT-LFA) was developed for rapid, user-friendly and quantitative detection of the NGAL in human serum(More)
