Revealing the temporal dynamics of soil organic carbon (SOC) requires a high-precision and reliability baseline estimate of SOC, but the accuracy of the SOC estimates is largely dominated by the model-calibrating approaches and the sample size used to training the models. In this study, we...

Mismatch between the road system and the spatiotemporal heterogeneity of traffic flow is a key reason for traffic congestion. Existing studies mainly focus on local regions or specific times (morning and evening peak) owing to the limited data source, while the spatiotemporal heterogeneity of...

Metal organic frameworks (MOFs) is a promising adsorbent for the removal of arsenic (As) from wastewater. The removal efficiency of As is influenced by many factors, such as the textural properties of MOFs, adsorption conditions, and As species. Examining all relevant factors through traditional...

Firms with more competitive threats from the product market are less likely to commit violations and pay lower penalties. These findings are robust to alternative measures, specifications, and subsamples, as well as different attempts that mitigate endogeneity concerns. Further analyses reveal...

Regression problems with time-series predictors are common in banking and many other areas of application. In this paper, we use multi-head attention networks to develop interpretable features and use them to achieve good predictive performance. The customized attention layer explicitly uses...

We develop an easily implementable yet effective process to achieve high power conversion efficiency (PCE) in newly-developed flexible single-crystal-like GaAs thin-film photovoltaic solar cells (PVSCs) on cheap metal tape. We study various techniques on the fabricated devices to passivate the...

The carboxyl functionalized ionic liquid ([mim(CH2)3COOH]Cl) was prepared as a linker to combine phosphotungstic acid (HPW) and Zr(IV) ion. The obtained [mim(CH2)3COO]3PW-Zr composite acted as a catalyst for removing DBT from liquid fuel with H2O2 as oxidant. As a result, [mim(CH2)3COO]3PW-Zr...

Co-hydrothermal carbonization (Co-HTC) coupled with co-product aqueous phase (AP) recirculation has huge potential to improve the hydrochar production. In this study, three model compounds, namely wheat straw cellulose (cellulose, Ce), xylan (hemicellulose, He), and soya-protein (protein, Pr)...

It is widely recognized that location is the primary determining factor of housing price. But to what extent the variation of housing price in Shanghai can be explained by the locational factor has not been empirically examined. In this paper, we examine the power of applying the hedonic method...
