Deep learning for gamma map prediction in breast IMRT verification
Medical Physics, Volume 53, Issue 11, November 2026.Abstract Background Patient‐specific quality assurance (PSQA) in radiotherapy commonly relies on global gamma passing rate (GPR) metrics, which summarize delivery agreement as a single scalar value and therefore provide limited information about the spatial location of dose delivery discrepancies.

New Phytologist, Volume 252, Issue 4, Page 1376-1395, November 2026.Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

New Phytologist, Volume 252, Issue 4, Page 1545-1564, November 2026.Identification of new regulators of Arabidopsis IRT1 endocytosis and metal transport using TurboID. TurboID proximity labeling of the Arabidopsis IRT1 root metal transporter identified new IRT1‐interacting proteins upon different metal regimes. Among validated candidates, the endosome‐localized NHX5 Na+ (K+)/H+ antiporter and the plasma membrane ...
