(author)When it comes to storing 3D city models in a database, the implementation of the CityGML data model can be quite demanding and often results in complicated schemas. As an example, 3DCityDB, a widely used solution, depends on a schema having 66 tables, mapping closely the CityGML architecture. In this paper, we propose an alternative (called ...conference paper 2024

Velthoen, J.J. (author), Dombry, Clément (author), Cai, Juan Juan (author), Engelke, Sebastian (author)Extreme quantile regression provides estimates of conditional quantiles outside the range of the data. Classical quantile regression performs poorly in such cases since data in the tail region are too scarce. Extreme value theory is used for extrapolation beyond the range of observed values and estimation of conditional extreme quantiles....journal article 2023

Piergentili, I. (author), Cai, Mao (author), Klemm, B. (author), Xu, B. (author), Luo, Sanzhong (author), Eelkema, R. (author)The redox balance in tumor and diseased cells often leads to the production of reactive oxygen species (ROS). Many ROS-responsive materials based on sulfur oxidation have been reported with the goal of achieving controlled delivery at the tumor. However, these materials often lack responsiveness to low ROS concentrations present in the tumor...journal article 2023

Cai, Z. (author), Wiertlewski, M. (author)The sensation of touching virtual texture and shape can be provided to a touchscreen user by varying the friction force. Despite the saliency of the sensation, this modulated frictional force is purely passive and strictly opposes finger movement. Therefore, it is only possible to create forces along the direction of movement and this...journal article 2023
