Overlap‐Kernel EPI: Estimating MRI Shot‐to‐Shot Phase Variations by Shifted‐Kernel Extraction From Overlap Regions at Arbitrary k‐Space Locations

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2131-2152, April 2026.
ABSTRACT Purpose In multi‐shot EPI, shot‐dependent phase fluctuations can introduce ghost artifacts, undermining advantages for enhancing resolution or reducing distortion, particularly in diffusion scans. Here, a novel self‐navigation strategy based on shift‐invariant kernel extraction is proposed, enabling robust estimation of phase inconsistencies ...

NMR‐Based Structural Analysis of Highly Substituted Pyridines From Kondrat'eva Aza‐Diels–Alder Cycloadditions

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 3, Page 324-332, March 2026.
We report the results from a kinetic and mechanistic investigation of an inverse‐electron‐demand Diels–Alder (IEDDA) cycloaddition involving an oxazole‐type diene synthesized via an Ugi–Zhu multicomponent reaction (UZ‐3CR). ABSTRACT Pyridines are a crucial class of heterocycles with widespread applications in natural products, pharmaceuticals, and ...

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

open access: yesAntipode, Volume 58, Issue 2, 2026.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...

Excluding Ascites From the GEMA‐Na Score Does Not Impact Outcome Predictions in Liver Transplant Candidates

open access: yesLiver International, Volume 46, Issue 3, March 2026.
ABSTRACT Background and Aims Although GEMA‐Na outperforms MELD 3.0 for liver allocation, concerns about the subjectivity of its ascites component persist. We compared the performance of a GEMA‐Na iteration that excludes ascites with other allocation scores.
