Evaluation of Topological Consistency in CityGML

open access: yesISPRS International Journal of Geo-Information, 2019
Boundary representation models are data models that represent the topology of a building or city model. This leads to an issue in combination with geometry, as the geometric model necessarily has an underlying topology.

Thematic Geovisualization of the Data Profile of Kaligesing, Purworejo, Central Java

open access: yesForum Geografi, 2019
The scientific field has a variety of purposes, one of which is the presentation of data and information which can be used by other parties to support their decision making. Moreover, the information is presented spatially.

Approximate MaxRS in spatial databases [PDF]

open access: yesProceedings of the VLDB Endowment, 2013
In the maximizing range sum (MaxRS) problem, given (i) a setPof 2D points each of which is associated with a positive weight, and (ii) a rectanglerof specific extents, we need to decide where to placerin order to maximize the covered weight ofr- that is, the total weight of the data points covered byr.

Fast Mining of Spatial Frequent Wordset from Social Database [PDF]

open access: yesSpatial Information Research, 25(2), 271-280 (2017), 2019
In this paper, we propose an algorithm that extracts spatial frequent patterns to explain the relative characteristics of a specific location from the available social data. This paper proposes a spatial social data model which includes spatial social data, spatial support, spatial frequent patterns, spatial partition, and spatial clustering; these ...

Towards a Scalable Dynamic Spatial Database System [PDF]

open access: yes, 2012
With the rise of GPS-enabled smartphones and other similar mobile devices, massive amounts of location data are available. However, no scalable solutions for soft real-time spatial queries on large sets of moving objects have yet emerged.

Molecular insights into the modulation of the 5HT2A receptor by serotonin, psilocin, and the G protein subunit Gqα

open access: yesFEBS Letters, Volume 599, Issue 6, Page 876-891, March 2025.
We explore 5HT2A receptor activation, a key target for psychedelic drugs, using molecular dynamics simulations. Without Gqα, the active receptor collapses to an inactive conformation, underscoring the G‐protein's role. Discovery of an intermediate “partially‐open” state and the higher affinity of ligands to the orthosteric binding site provides ...
