Trinidad Novoa - Hydrogen-rich superconductors: efficient estimations of Tc from real-space descriptors

The search for high-temperature superconductors has advanced significantly in the last ten years, with many hydrogen-rich compounds exhibiting superconductivity above 200 K. However, their stability at extreme pressures limits practical applications. Theoretical prediction of new compounds is hindered by expensive calculations of critical temperatures (Tc)...

Andrew Smith – Simple generalizations in stereoselective catalysis enable the algorithmic discovery of new enantioselective solutions

Structure-activity relationships describe trends between chemical features and subsequent function. As the modeled activity becomes more complex, the relationships drawn often rely on more specific features, inhibiting the realization of general chemical intuition. Notably, trends in stereoselective catalysis constitute one such relationship where complex interactions...

Hannes Stärk and Bowen Jing – Dirichlet Flow Matching with Applications to DNA Sequence Design

Abstract: We develop Dirichlet flow matching on the simplex based on mixtures of Dirichlet distributions as probability paths. In this framework, we derive a connection between the mixtures' scores and the flow's vector field that allows for classifier and classifier-free guidance. On DNA sequence generation...
