Crystal structural stability of V<Subscript>2</Subscript>O<Subscript>3</Subscript> under high pressure has been investigated by first-principles calculations. Our results demonstrate that the phase-transition sequence of V<Subscript>2</Subscript>O<Subscript>3</Subscript> is from corundum structure to Gd<Subscript>2</Subscript>S<Subscript>3</Subscript>-type structure at 30 GPa, then to the Th<Subscript>2</Subscript>S<Subscript>3</Subscript>-type structure at 52 GPa, finally to...</subscript></subscript></subscript></subscript></subscript></subscript></subscript></subscript>

Constructing a theoretical framework and using a survey data of 294 customers from 25 supermarkets in Beijing, this paper studies the willingness to pay (WTP) for additive-free Mooncakes in Beijing and finds that age and income are important for WTP for “food safety” in China. Income is...

We consider Poisson’s equation for discrete-time single-birth processes, and we derive its solutions by solving a linear system of infinitely many equations. We apply the solution of Poisson’s equation to obtain the asymptotic variance. The results are further applied to birth–death...

Consumers are facing a trade-off between the benefits of an increase in the length of the shelf life of food, such as low food costs, and the potential health damages caused by food preservatives. However, few studies in the current literature place emphasis on food preservatives, neither from a...

Accurate estimation of the state of charge (SOC) of batteries is one of the key problems in a battery management system. This paper proposes an adaptive SOC estimation method based on unscented Kalman filter algorithms for lithium (Li)-ion batteries. First, an enhanced battery model is proposed...

This paper investigates how different corporate associations may influence consumer evaluations and purchase intention in response to cause-related marketing (CRM) and whether this impact is contingent on congruence between the cause and the company. Our experimental study, based on 660...

Estimation errors or uncertainities in expected return and risk measures create difficulties for portfolio optimization. The literature deals with the uncertainty using stochastic, fuzzy or probability programming. This paper proposes a new approach to treating uncertainty. By assuming that the...

Society calls for customers to participate in carbon offset programs and purchase carbon offset products in response to the threats currently posed by severe environmental pollution. To promote these products, companies often use carbon emission calculators. However, the effectiveness of this...
