Incremental Evaluation of Top-κ Combinatorial Metric Skyline Query
, 2015 In this paper, we define a novel type of skyline query, namely top-κ combinatorial metric skyline (κCMS) query. The κCMS query aims to find k combinations of data points according to a monotonic preference function such that each combination has the ...

Caching Dynamic Skyline Queries [PDF]
, 2008 Given a query tuple q, the dynamic skyline query retrieves the tuples that are not dynamically dominated by any other in the data set with respect to q. A tuple dynamically dominates another, w.r.t. q, if it has closer to q's values in all attributes, and has strictly closer to q's value in at least one.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

MapReduce Algorithm for Variants of Skyline Queries: Skyband and Dominating Queries
Algorithms, 2019 The skyline query and its variant queries are useful functions in the early stages of a knowledge-discovery processes. The skyline query and its variant queries select a set of important objects, which are better than other common objects in the dataset.

Location Selection Query in Google Maps using Voronoi-based Spatial Skyline (VS2) Algorithm
JOIN: Jurnal Online Informatika, 2021 Google Maps is one of the popular location selection systems. One of the popular features of Google Maps is nearby search. For example, someone who wants to find the closest restaurants to his location can use the nearby search feature. This feature only

Ranking Methods for Skyline Queries
Knowledge and Information SystemsAbstract Multi-criteria decision analysis in databases has been actively studied, especially through the Skyline operator. Yet, few approaches offer a relevant comparison of Pareto optimal, or Skyline, points for high cardinality result sets.
