, 2009 Databases are computer systems designed to store information in a systematic way so that their contents can be easily accessed, managed, changed, and augmented. Spatial databases are such systems designed specifically to include data with spatial attributes, such as geographical location, distance, and extent.

Capacity constrained assignment in spatial databases [PDF]
Proceedings of the 2008 ACM SIGMOD international conference on Management of data, 2008 Given a point set P of customers (e.g., WiFi receivers) and apoint set Q of service providers (e.g., wireless access points),where each q 2 Q has a capacity q.k, the capacity constrainedassignment (CCA) is a matching M Q × P such that (i)each point q 2 Q (p 2 P) appears at most k times (atmost once) in M, (ii) the size of M is maximized (i.e ...

Decoding multicellular interaction networks–a new horizon in tumor microenvironment research
Molecular Oncology, Volume 19, Issue 4, Page 957-960, April 2025.Cells in the tumor microenvironment influence tumor establishment and progression through an elaborate array of cellular interactions. Integrating transcriptomic, spatial, and intercellular crosstalk data at single‐cell resolution unveil complex, functionally distinct multicellular circuits.

Consistent Query Answering under Spatial Semantic Constraints [PDF]
arXiv, 2011 Consistent query answering is an inconsistency tolerant approach to obtaining semantically correct answers from a database that may be inconsistent with respect to its integrity constraints. In this work we formalize the notion of consistent query answer for spatial databases and spatial semantic integrity constraints.

Molecular Oncology, EarlyView.Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

OpenGeoBase: Information Centric Networking meets Spatial Database applications - Extended Version [PDF]
arXiv, 2016 This paper explores methodologies, advantages and challenges related to the use of Information Centric Networking (ICN) for realizing distributed spatial databases. Our findings show that the ICN functionality perfectly fits database requirements: routing-by-name can be used to dispatch queries and insertions, in-network caching to accelerate queries ...
