Rice is a staple food in Vietnam, and the concern about rice much greater than that for other foods. Preventing fraud against this product has become increasingly important order to protect producers consumers from possible economic losses. The adulteration of done by mixing, or even replacing, high-quality with cheaper rice. This highlights need analytical methodologies suitable its authentica...

Counterfeit integrated circuits (ICs), commonly known as microcircuits, pose a significant threat to the global electronics component supply chain and are becoming more difficult to detect as the counterfeiters increase their level of sophistication. They are of great concern to industry and government [1] because a system malfunction can present situations that cause mission failures, health a...

The medicinal plant Ferula has been widely used in Asian medicine, especially in Uyghur medicine in Xinjiang, China. Given that various substitutes and closely related species have similar morphological characteristics, Ferula is difficult to distinguish based on morphology alone, thereby causing confusion and threatening the safe use of Ferula. In this study, internal transcribed spacer 2 (ITS...

E-commerce has become one of the major consumption patterns currently. Understanding consumer e-commerce shopping behavior helps to improve the competitiveness of enterprises. The purpose of this study is to examine service justice as the antecedent factor of dysfunctional customer behavior (DCB) and how it interacts with negative emotion and service dissatisfaction, which in turn, affect DCB. ...

Logistical management has been advanced rapidly in these years, taking advantage of the broad connectivity of the Internet. As it becomes an important part of our lives, it also raises many challenging issues, e.g., the counterfeits of expensive goods pose a serious threat to supply chain management. As a result, path authentication becomes especially important in supply chain management, as it...

It is very difficult to identify Angelicae sinensis radix (Danggui) when it is processed into Chinese patent medicines. The proposed internal transcribed spacer 2 (ITS2) is not sufficient to resolve heavily processed materials. Therefore, a short barcode for the identification of processed materials is urgently needed. In this study, 265 samples of Angelicae sinensis radix and adulterants were ...

Bile acids as characteristic compounds of human and animal bile are major endogenous products of cholesterol and play very important roles in cholesterol homeostasis, lipid absorption and production of bile flow. At present, bile acids are useful biomarkers and signaling molecules for the diagnosis or treatment of many diseases in clinic. Various analytical methods, from overall to individual, ...

Despite cryptographic breakthroughs in the area of digital cash and the rapid advance of information technology, physical cash remains the dominant currency: it is easy to use and its exchanges are largely independent of computing devices. However, physical cash is vulnerable to rising threats such as high quality, government-mandated forgeries. Can a hybrid of physical and digital cash protect...
