Root trait dynamics of historical canola varieties under low and high nitrogen supply
The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Nitrogen fertilizer is a major input cost in crop production, making it crucial to enhance nitrogen use efficiency (NUE) to reduce fertilizer dependence without compromising yields. Root system architecture (RSA) is a key determinant of nutrient acquisition, particularly under nutrient‐limited conditions.

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI
Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3608-3615, June 2026.ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+ field profiles were conceptualized and constructed.

NMR in Biomedicine, Volume 39, Issue 6, June 2026.Electromagnetic interference (EMI) is a significant challenge for low‐field MRI. Traditional EMI mitigation approaches either limit portability or demand advanced hardware. We present FENCE (Flexible Electromagnetic Noise reduCtion Endo‐shield), a novel approach for EMI mitigation using flexible PCBs placed inside the RF coil.

Refusal and Aporia: At the Limits of Anthropological Knowledge
American Anthropologist, Volume 128, Issue 2, Page 339-348, June 2026.ABSTRACT As anthropologists increasingly take up refusal, opacity, and other forms of resistance to surveillance and subjugation, this paper questions what implications this has for the discipline in practice. Considering anthropology's enduring centrality in defining what it means to be human, including the various ways that this category has been ...
