Anatase TiO2 nanosheets supported on reduced graphene oxide (RGO) were synthesized via a one-step, solvothermal method. During the solvothermal step, graphene oxide (GO) was reduced to RGO, and, subsequently, anatase TiO2 with 73.7% exposed {001} facets was grown in situ on the surfaces of the RGO nanosheets. Compared with pure TiO2, the RGO/TiO2 hybrid(More)
Event management is imperative for manufacturing enterprises. Manufacturing events have to be captured, categorized, analyzed and acted upon in real-time fashions. This paper presents the concept of anticipative event management (AEM) which is a new approach to manufacturing event management. AEM focuses on predicting the events that are going to happen and(More)
The negative secrecy capacity case is an important problem for secure wiretap channel polar coding, however former polar coding schemes have not considered this negative case because physical layer channel coding cannot achieve a positive secrecy rate under this condition. In this paper, a chaos embedded polar coding scheme is proposed which can achieve a(More)
The migration of vascular smooth muscle cells (VSMCs) is an important process in many physiological events. It is of paramount importance to control the migration rate and direction of VSMCs by biomaterials. In this paper, a density gradient of basic fibroblast growth factor (bFGF) was fabricated using an injection method and the bio-conjugation between(More)
Buffer overflow attacks have been causing serious security problems for decades. While numerous approaches have been proposed to prevent stack overflows, heap overflows remain a security threat and a frequent source of bugs. Embedded systems can be easily attacked by the heap overflow attacks. In this paper, based on analyzing the security of an embedded(More)
Quality of hardware implementation is an important factor in selecting the NIST SHA-3 competition finalists. As a third-round candidate algorithm of SHA-3, BLAKE algorithm achieved excellent performance in software implementation. In order to adapt to the resource-limited and high-speed system, this paper carried out a [4G] hardware architecture based on(More)
