Small extracellular vesicles (sEVs) are closely associated with physiological and pathological processes of a variety of diseases, such as osteosarcoma. Developing a simple and sensitive sEVs detection strategy is crucial to the in-deep study and clinical diagnosis of many disease. We developed...

To meet the requirements of efficient adsorption of atmospheric pollutant SO 2 and low energy consumption regeneration of adsorbent, biomass carbon materials modified by metal oxides were prepared under microwave heating and the effects such as microwave power, loading of iron oxides, and...

Using a unique dataset based on daily and hourly high-yield bond transaction prices, we find the informational efficiency of corporate bond prices is similar to that of the underlying stocks. We find that stocks do not lead bonds in reflecting firm-specific information. We further examine price...

The properties of variance ratio tests across trading and non-trading periods are examined using the generalized method of moments. For the case of opening and closing return variances, the joint tests indicate that the null hypothesis that the variance of opening returns equals the variance of...
