Algae is a very promising source for renewable energy production since it can fix the greenhouse gas (CO2) by photosynthesis and does not compete with the production of food. Compared to microalgae, researches on biofuel production from macroalgae in both academia and industry are at infancy for...

Recently spectral perturbations, involving eigenvalue and eigenvector perturbations, which have attracted more attentions than conventional topological perturbations, are used to analyze and promote the robustness of complex networks. However, to the best of our knowledge, the study of...

In this work, an Al2O3-coated SiC foam monolith was used as the support of a Ni-based catalyst, which was applied for coupling partial oxidation and steaming reforming of methane to produce syngas or hydrogen. This monolithic catalyst showed excellent structural stability in a 900h endurance...

The receiver operating characteristic (ROC) curve may be used to evaluate the performance of a biomarker measured on continuous scale to predict disease status or clinical condition. Motivated by the need for novel study designs with better estimation efficiency and reduced study cost, we...

The area under a ROC curve (AUC) and partial area under a ROC curve (pAUC) are important summary measures useful in assessing the accuracy of a diagnostic test or a biomarker in discriminating true disease status. We consider nonparametric estimation of AUC and pAUC under a test-result-dependent...

Due to the expected importance of unconventional oil in China's domestic oil supply, this paper first investigates the four types of China's unconventional oil resources comprehensively: heavy and extra-heavy oil, oil sands, broad tight oil and kerogen oil. Our results show that OIP...

As the world's second largest oil importer, China has been one of the important factors which affect the global oil market. In recent years, China has attained great international trade surplus through exporting a large number of “Made in China” products even during the global economic...

As China’ largest oilfield, Daqing is of great importance to China, this paper analyzes the status of the Daqing oilfield and forecasts its ultimate recoverable reserves by use of the URR model. The forecast results are presented for three scenarios which show that the ultimate recoverable...
