We study the existing models for right-censored competing risks data and with masked failure cause. By introducing a new random variable hidden behind the current models, we give a practical interpretation of the symmetry assumption made by almost all researchers in this field. We further point...

The synthesis of long-chain esters in reactive extraction process using bifunctional deep eutectic solvent (DES) demands a wide solvent selection range and optimal solvent choice. In this work, first, novel halogen-free DESs based on triazole and p-toluenesulfonic acid (PTSA) or benzenesulfonic...

Electric unmanned vessels (EUVs) are a necessary part of a zero-carbon future of marine transport. There is significant knowledge of driverless technology on the one hand and on electric power on the other. However, less is known of dynamic evolution of core technologies of EUVs and future...

This article reports the results of an empirical study on summertime environmental performances of a pocket park in Hong Kong. The results suggest that (i) wind condition has a critical impact on outdoor air temperature (Ta), especially in a tropical area like Hong Kong and (ii) building...
