Phase transformations in Ti-Nb-Ta and Ti-Nb-Ta-Zr alloys

Abstract: Phase transformations in solution treated and quenched Ti-(13-26) Nb-(22-38) Ta (wt.%) and Ti-(13-35.5) Nb-(5-22) Ta-(4-7.2) Zr alloys have been studied. It has been observed that phase transformations in these alloys are sensitive to both composition and cooling rate. In ternary alloys, water and oil quenching resulted in the formation of orthorhombic martensite (α′′) in a retained β + ωathermal matrix, whereas slower cooling showed evidence of fine α and ωisothermal formation within the β matrix. Increase of Nb + Ta content decreases the volume percentage of martensite. Moreover, addition of Zr stabilized the β phase, lowered the martensite start temperature and suppressed ω formation. Finally, dynamic moduli of air cooled quaternary alloys showed that the modulus was sensitive to the composition, a minima at Nb/Ta ratio of 12.0 and 5 at% Zr being observed, this minimum in dynamic modulus being consistent with ω phase suppression.

A brief survey of Cryptocurrency systems

Abstract: Cryptocurrencies have emerged as important financial software systems. They rely on a secure distributed ledger data structure; mining is an integral part of such systems. Mining adds records of past transactions to the distributed ledger known as Blockchain, allowing users to reach secure, robust consensus for each transaction. Mining also introduces wealth in the form of new units of currency. Cryptocurrencies lack a central authority to mediate transactions because they were designed as peer-to-peer systems. They rely on miners to validate transactions. Cryptocurrencies require strong, secure mining algorithms. In this paper we survey and compare and contrast current mining techniques as used by major Cryptocurrencies. We evaluate the strengths, weaknesses, and possible threats to each mining strategy. Overall, a perspective on how Cryptocurrencies mine, where they have comparable performance and assurance, and where they have unique threats and strengths are outlined.

Explaining Real-Life Events: How Culture and Domain Shape Attributions

Abstract: Several lines of experimental research have shown that attributional styles are affected by the attributor's culture, inferential goals, and level of cognitive processing. Can these findings be replicated in natural settings? This study compared the attributions made in two domains (sports articles and editorials) of newspapers published in two culturally distinct countries (Hong Kong and the United States). Consistent with the cross-cultural research, attributions were less dispositional in the East than in the West. This cultural difference was weaker in editorials than in sports articles. The authors argue that the higher level of complexity, accountability, and uncertainty in editorials increased the cognitive effort expended to make attributions, which, in turn, attenuated their extremity. Implications for the mixed model of social inference are discussed.
