High Voltage, Volume 11, Issue 2, Page 351-359, April 2026.ABSTRACT The electromagnetic wave produced by a partial discharge (PD) covers a broad range of frequencies, from a few kHz to several 100 MHz. Because of the nonlinear response of the stator winding, each frequency component of the PD pulse experiences different levels of attenuation as it travels through the winding structure. Consequently, the choice

BMEMat, Volume 4, Issue 1, March 2026.We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐
