MolRec: Chemical Structure Recognition at CLEF 2012

Performance evaluation of MolRec at the CLEF 2012 competition reveals a large performance gap between the automatic evaluation set (94-96% accuracy) and the manual evaluation set of complex patent structures (46-59% accuracy), with systematic analysis of failure modes including character grouping bugs, touching characters, and four-way junction vectorization.

The Surface of Venus: Stratigraphy and Resurfacing History

Basilevsky and Head’s comprehensive synthesis reveals a planet that undergoes catastrophic global resurfacing events. We explore the “stagnant lid” model, the synchronous stratigraphy, coronae, and the divergence of Venus’s geological history from Earth’s.

Dark Side of Forces: Non-Conservative ML Force Models

ICML 2025 analysis rigorously quantifying when non-conservative force models (which predict forces directly) fail in molecular dynamics, demonstrating simulation instabilities and proposing hybrid architectures that capture speed benefits without sacrificing physical correctness.
