An energy gap is, in principle, a dominant parameter in superconductivity. However, this view has been challenged for the case of high-Tc cuprates, because anisotropic evolution of a d-wave-like superconducting gap with underdoping has been difficult to formulate along with a critical temperature Tc. Here we show that a nodal-gap energy 2ΔN closely follows(More)
A base-isolated building may sometimes exhibit an undesirable large response to a long-duration, long-period earthquake ground motion and a connected building system without base-isolation may show a large response to a near-fault (rather high-frequency) earthquake ground motion. To overcome both deficiencies, a new hybrid control system of base-isolation(More)
Understanding the overall features of magnetic excitation is essential for clarifying the mechanism of Cooper pair formation in iron-based superconductors. In particular, clarifying the relationship between magnetism and superconductivity is a central challenge because magnetism may play a key role in their exotic superconductivity. BaFe2As2 is one of ideal(More)
A 65-year-old man was admitted with penile tenderness and dysuria due to priapism. Enhanced computed tomography revealed metastatic tumors in the liver, lung, sacrum and lymph nodes. Advanced rectal cancer, detected by colonoscopy as a primary tumor, was treated with chemotherapy (FOLFOX4). Although the rectal cancer showed no change, five months of(More)
