C60 films were fabricated by vacuum sublimation and studied with dielectric spectroscopy regarding glass transition. With annealing, the dielectric loss peaks decreased in height, and the apparent activation energy deduced from their frequency dependence dropped in magnitude. The peaks, broad...

In this paper, a discrete time series of stock price process is modeled by the two-dimensional lattice-oriented bond percolation system. Percolation theory, as one of statistical physics systems, has brought new understanding and techniques to a broad range of topics in nature and society....

Rice can potentially pose serious health risks due to its highly efficient arsenic (As) uptake. Sulfur (S) is not only an essential macronutrient, but it also has the ability to decrease As accumulation. In the present study, a hydroponic experiment was conducted to investigate the mechanisms...

We examine whether and how the exercising of rights by the regulatory minority shareholder impacts firms' cost of equity. Using a hand-collected sample from the CSISC, a novel regulatory investor protection institution controlled by the China Securities Regulatory Commission, we find that the...

An audit committee (AC) report is the primary channel through which investors learn about the responsibilities and activities of an AC. AC members may use personal language (“we”) or impersonal language (“the audit committee”) in an AC report. Psychology research suggests that personal...

Section 404 of the Sarbanes-Oxley Act requires management to assess and disclose the effectiveness of their internal controls over financial reporting (ICFR). However, the regulation does not provide specific guidance regarding the communication style to be used in these reports. Our analysis of...

Recently, rare-earth doped phosphors have been newly developed and applied in hot issues such as phosphor-converted light-emitting diodes (pc-LEDs)，anti-counterfeiting, and fingerprint visualization. Herein, an Eu 3+ -activated CaGdSbWO 8 (CGSW) red phosphor was synthesized by a...
