We point out that the effective action of hot Yang–Mills theories has semiclassical solutions, which are naturally identified with monopole world lines, “frozen” into the short imaginary time dimension. The solutions look like wall junctions: lines along which N electric ZN domain walls come together. They are instrumental in reconciling explicit perturbative calculations at high temperature wi...

Background and Aim: Renal cell carcinoma (RCC) is the 13th most common cancer worldwide and accounts for 4% of all adult malignancies. Herein the state of the art and recent advances in cross-sectional radiological imaging applied to RCC are reviewed, including ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography. Methods: Literature search of peer-...
