Critical transport properties of random metals in large magnetic fields.

abstract：:The relative stabilities and structural properties of a representative set of 20 ALS-mutant Cu,Zn-superoxide dismutase apoproteins were examined by using differential scanning calorimetry and hydrogen-deuterium (H/D) exchange followed by MS. Contrary to recent reports from other laboratories, we found that ALS-mutant ...
