Liquid fuel such as bio-gasoline derived from biomass is widely recognized as a potential substitution for the diminishing fossil fuels due to its abundance of raw materials and lower greenhouse gas emissions. In this work, Ni/HZSM-5 catalysts were developed by incipient impregnation method and...

In this paper we demonstrate that a higher-ranking principal component of the predictor tends to have a stronger correlation with the response in single index models and sufficient dimension reduction. This tendency holds even though the orientation of the predictor is not designed in any way to...

This study investigates whether an auditor's experience of litigation in the recent past affects subsequent financial reporting quality. At the audit firm level, we find accounting misstatements occur significantly less (more) often after audit firms are sued (not sued). At the audit office...

Along with the sequent completion of Manwan and Dachaoshan Dam, the river continuum of the middle and lower reaches of the Lancang River was separated into three types of segments: reservoir, below-dam segment and downstream flowing segment. The long-term series of water quality and river flow...

Purpose The purpose of this study is to designed a robot odometry based on three dimensional (3D) laser point cloud data, inertial measurement unit (IMU) data and real-time kinematic (RTK) data in underground spatial features and gravity fluctuations environment. This method improves the mapping...

In the current literature, fiscal policy is usually characterized by a singleequation rule, in which primary surplus is generally dened as a function of lagged government debt and other controlled variables. To apply Ordinary Least Squares (OLS) method on the single-equation rule has been one of...
