This paper explores the racial differences in politicians’ persistence in elections. Empirical data from California city council elections and a close election regression dis- continuity design (CERDD) suggest that losing an election causes 70% attrition in rerunning for office. After a loss,...

Hot workability of a forged beta gamma Ti-44Al-6Nb-1Mo-0.3 (B, Y, La, Ce) alloy was studied on a Gleeble-3800 thermal simulation machine under variable conditions. The flow stress and microstructural evolution were analyzed carefully after deformed at variable strain and holding time. All true...

Porous CoAl 3 intermetallic is a candidate material in the field of catalytic and filtration due to its high porosity, good thermostability and quasicrystal structure. However, its rapid and reliable preparation are still a challenge, and the high-temperature antioxidant mechanism need to be...
