In a general traffic network under some widely used assumptions, this paper proves that the level of service, represented by the volume-capacity (v/c) ratio, offered by a profit-maximizing private firm on a private toll road is independent of another competitor's choice of capacity and toll rate...

The quality of reclaimed land not only relates to the way of reclamation, but also has close relations to farmers’ living standard and households’ behaviors. Taking the farmland in the reclamation region of the Liuxin County, Tongshan Town, Xuzhou as the survey objects, we conduct...

We present a new approach for content analysis to quantify document tone. We find a significant relation between our measure of the tone of 10-Ks and market reaction for both negative and positive words. We also find that the appropriate choice of term weighting in content analysis is at least...

This paper sets forth a family of models of light-duty plug-in electric vehicle (PEV) fleets, appropriate for conducting long-term national-level planning studies of the energy and transportation sectors in an integrated manner. Using one of the proposed models, three case studies on the...

This paper develops an equilibrium modeling framework that captures the interactions among availability of public charging opportunities, prices of electricity, and destination and route choices of plug-in hybrid electric vehicles (PHEVs) at regional transportation and power transmission...

For each S&P 500 stock, I calculate the rolling correlation between the VIX and the premium of butterfly at different strikes. The butterfly that co-moves most positively with VIX reveals the expectation of the stock’s return in the future market crash. I call this return the Butterfly Implied...

The geometric structures, energetic and electronic properties of global minima of the AlBe n ( n = 1–12) clusters have been systemically studied by using the hybrid density functional theory [B3LYP] and coupled cluster [CCSD(T)] methods. It is found that the impurity Al atom is externally...
