Abstract Doubly robust (DR) estimators are an important class of statistics derived from a theory of semiparametric efficiency. They have become a popular tool in causal inference, including applications to dynamic treatment regimes. The doubly robust estimators for the mean response to a...

The plasma produced by Dielectric Barrier Discharge (DBD) has a very important application in the field of aerodynamics. The plasma generator needs high-voltage and high-frequency power supply. Due to the existence of internal resistance of the power supply, the impedance characteristics of the...

The power frequency high voltage divider is widely used to measure the power frequency high voltage and it is an important measuring instrument for high voltage test. Whether it is accurate or not directly affects the insulation monitoring level of power equipment closely related to the safety...

This study investigates whether and how the perception of carbon abatement pressure affects corporate financing behavior. The results show that carbon abatement pressure increases corporate cash holdings via the channel of financing constraints, and this positive relationship still holds after a...

We present a two-stage scheduling approach including proactive and reactive scheduling to solve the ground resource scheduling problem with uncertain arrival time. In the first stage, an integer programming model is constructed to minimize the delay and transfer costs. After solving this model,...
