Data fusion of gamma and x‐ray spectra via Common Dimensions for soil erosion characterization

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study explores the synergistic application of energy dispersive x‐ray fluorescence (EDXRF) and gamma‐ray spectrometry (GRS) raw spectra to characterize soil redistribution. The evaluation employs Common Dimensions (ComDim), a multiblock non‐supervised machine‐learning technique, to identify shared latent patterns across nuclear and atomic

Hydrogen‐State‐Engineered Oxide Semiconductor Channels Enabling Reliable 2T0C DRAM Operation

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
We introduce a three‐step hydrogen annealing method for oxide semiconductor devices that modulates hydrogen incorporation and its passivation behavior. Consequently, interface traps are suppressed, whereas the mobility, reliability, and data retention of the IGO‐based 2T0C DRAM are simultaneously improved.
