Using the first-principles calculations based on density functional theory, we investigate the more d-electrons doping effects on the electronic structure and magnetism of the parent inverse Heusler alloy Ti<Subscript>2</Subscript>CoAl by the substitution of Nb and V atoms for Ti(A) and Ti(B) atoms locating at the two...</subscript>

The growth-optimal portfolio optimization strategy pioneered by Kelly is based on constant portfolio rebalancing which makes it sensitive to transaction fees. We examine the effect of fees on an example of a risky asset with a binary return distribution and show that the fees may give rise to an...

The effect of atomic antisite and swap defects on the electronic and magnetic properties of Ti<Subscript>2</Subscript>NiAl inverse Heusler alloy is investigated by the first-principles calculations within density functional theory. In the ordered Ti<Subscript>2</Subscript>NiAl alloy, there are eight antisites and five swaps which are...</subscript></subscript>

One of the challenges facing intermodal integration is that the planning framework needed for it lacks appropriate measures of level of service that cut across the modes involved and the connections between them. In this study we develop a framework and a set of metrics of level of service in a...

Little quantitative research has been devoted to voluntary climate actions at the local level in comparison to those at federal and state levels. It is unclear why some cities act as leaders in the fight against climate change, some act as followers, while others remain laggards. This study...

A sizable empirical literature relates a nation's Olympic performance to socioeconomic factors by adopting linear regression or a Tobit approach suggested by Bernard and Busse (2004). We propose an alternative model where a nation's medal share depends on its competitiveness relative to other...
