Copper sulfides (Cu x S) have been considered as candidates for sodium ion battery (SIB) anodes because they are environmentally friendly and have large theoretical capacity. Whereas, the cycle stability and capacity of Cu x S are still challenge for their practical applications. Here,...

To estimate Brillouin frequency shift with high accuracy and less computational burden, the mixed moment is used to estimate it for the distributed optical fiber sensor. Its computational burden is much less than that of the typical algorithms. Meanwhile, it is free of curve fitting and...

While the poly(2-hydroxyethyl methacrylate) (PHEMA) hydrogel is highly biocompatible and stable, its actual application for soft-tissue replacement is severely limited due to the poor mechanical properties. Herein, we develop a facile strategy to construct PHEMA-based hydrogels with the highest...

Purpose – The purpose of this paper is to examine chief financial officer (CFO) qualification improvement associated with restatements and restatement characteristics (restatement materiality). The study is motivated by recent high-profile financial scandals and increasing instances of...

We examine the rounding phenomenon (called <i>window dressing</i>) in financial reporting of U.S. high-tech and low-tech firms. By requiring that investments in research and development be expensed as incurred, the generally accepted accounting principles provide low-tech firms with a larger set of...
