Compatibility and Accuracy Verification of CADmesh-Based Complex Geometry Modeling in Geant4
arXiv:2606.06508v1 Announce Type: new Abstract: Geant4 Monte Carlo simulation relies on the Constructive Solid Geometry (CSG) method for complex geometric modeling. This method has low efficiency and a high application threshold. Importing triangular facet formats such as STL/OBJ via CADmesh is a promising alternative, but systematic evaluations of format compatibility, geometric accuracy, and physical simulation deviations are lacking.
Czech MEP’s undeclared think-tank role raises conflict-of-interest questions
BRUSSELS — Alexandr Vondra, a Czech member of the European Parliament, did not disclose his role as honorary chair of an influential think tank in the Czech Republic, despite negotiating files affecting the companies funding the organization. Transparency International argues that Vondra’s failure to disclose his relationship with the Prague Center of Transatlantic Relations may violate the European Parliament’s code of...
Contextual Scenario Generation for Two-Stage Stochastic Programming
arXiv:2502.05349v2 Announce Type: replace-cross Abstract: Two-stage stochastic programs (2SPs) are widely used for decision-making under uncertainty, but their practical deployment is often limited by the large number of scenarios needed to approximate the conditional distribution of uncertain outcomes. We study contextual scenario generation: given contextual information, learn to produce a small, user-specified set of surrogate scenarios that, when used as input into the 2SP, lead to...
