PXtal: Learning to Align Powder X-Ray Diffraction and Crystal Structures under Information Asymmetry across Modalities

Zhuoran Yang, Christopher M. Collins, Bei Peng et al. · 2026

Scientific multimodal learning commonly assumes that paired views are comparably informative. Powder X-ray diffraction (PXRD) makes this mismatch explicit: compressing a three-dimensional crystal structure into a one-dimensional diffraction pattern loses information and makes the pattern harder to connect to the crysta …

Robust blind unmixing: A geometric approach to overcoming basis variation

Dumitru Mirauta, Vladimir V. Gusev, Michael W. Gaultois et al. · 2026

Signal separation problems are common in science. A prominent example of this occurs during the use of diffraction or spectroscopy to identify the individual components of a mixture by measuring it. In the simplest case, the measured signal is a linear combination of basis patterns corresponding to the constituent part …
