A Scalable Algorithm for Maximizing Range Sum in Spatial Databases [PDF]
Proceedings of the VLDB Endowment, 2012 This paper investigates the MaxRS problem in spatial databases. Given a set O of weighted points and a rectangular region r of a given size, the goal of the MaxRS problem is to find a location of r such that the sum of the weights of all the points ...

Land, 2020 Many cities lack complex spatial databases that can answer the question “What does a given green space offer?” This complicates the lives of inhabitants, planners, and local authorities.

New plane-sweep algorithms for distance-based join queries in spatial databases
GeoInformatica, 2016 Efficient and effective processing of the distance-based join query (DJQ) is of great importance in spatial databases due to the wide area of applications that may address such queries (mapping, urban planning, transportation planning, resource ...

The SSP-Tree: A Method for Distributed Processing of Range Monitoring Queries in Road Networks
ISPRS International Journal of Geo-Information, 2017 This paper addresses the problem of processing range monitoring queries, each of which continuously retrieves moving objects that are currently located within a given query range.

Visualization of 3D Survey Data for Strata Titles
ISPRS International Journal of Geo-Information, 2020 Major cities and urban areas are beginning to develop and use 3D properties and public facilities. Consequently, 3D cadastral surveys are increasingly being employed for strata unit ownership registration as a part of land administration services.

The effectiveness of DNA databases in relation to their purpose and content : a systematic review [PDF]
, 2019 Different stakeholders use forensic DNA databases for different purposes; for example, law enforcement agencies use them as an investigative tool to identify suspects, and criminologists use them to study the offending patterns of unidentified suspects ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

A storage and access architecture for efficient query processing in spatial database systems [PDF]
, 1993 Due to the high complexity of objects and queries and also due to extremely large data volumes, geographic database systems impose stringent requirements on their storage and access architecture with respect to efficient query processing.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
FEBS Letters, EarlyView.Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...
