Calcifying Fibrous Tumor of the Pleura: A Rare Case with an Unusual Presentation on CT and MRI
Calcifying fibrous tumors (CFTs) are rare benign mesenchymal tumors consisting of hyalinized collagenous fibrotic tissue with a lymphoplasmacytic infiltrate and dystrophic calcifications. Radiographic features have seldom been described, and there are no

Giant Magnetoresistance Effect in the Metal-Insulator Transition of Pyrochlore Oxide Nd2Ir2O7 [PDF]
We investigated the magnetoresistance (MR) effect of the pyrochlore oxide Nd2Ir2O7, which shows a metal-insulator transition at T_MI =33 K. A small positive MR effect was observed in the metallic state above T_MI, while a large negative MR effect was ...

Magnetoresistance behavior of a ferromagnetic shape memory alloy: Ni_1.75Mn_1.25Ga [PDF]
A negative-positive-negative switching behavior of magnetoresistance (MR) with temperature is observed in a ferromagnetic shape memory alloy Ni_1.75Mn_1.25Ga. In the austenitic phase between 300 and 120 K, MR is negative due to s-d scattering. Curiously,

Case report: Acute calcific discitis with intravertebral disc herniation in the dorsolumbar spine
Acute calcific discitis is a rare but well-known condition of unknown etiology. In symptomatic cases, the most common site is the cervical spine. We describe the CT scan and MRI findings in a symptomatic patient, with a lesion in the dorsolumbar spine.
