Process programming is regarded as a critical approach in many cooperative process related areas including software engineering, workflow management, business process management, etc. Many process models, languages, and corresponding runtime support systems have been developed. We argue that a comprehensive library for process programming is essential for(More)
Process modeling is a central topic of research on Computer Supported Cooperative Work (CSCW). Uniformity and flexibility in work representation and process enactment are two primary goals. We develop a novel meta-model capable of modeling uniformly a wide range of cooperation scenarios. We will discuss the key elements of the model and its computerized(More)
Tetrabromobisphenol A (TBBPA) is a widely used brominated flame retardant. A sensitive and selective indirect competitive biotin-streptavidin-amplified enzyme-linked immunosorbent assay (BA-ELISA) was developed for detecting TBBPA. The optimal hapten of TBBPA was 2-(2,6-dibromo-4-(2-(3,5-dibromo-4-hydroxyphenly)propan-2-yl)) acetic acid. Several(More)
Tris(2,3-dibromopropyl) isocyanurate (TBC) is a novel brominated flame retardant (BFR) that is widely used to substitute the prohibited BFRs throughout the world. With the development of research, the potential environmental and ecological harms of TBC have been revealed. For sensitive and selective detecting TBC, an indirect competitive(More)
Process technologies play an increasingly important role as the world is being digitalized in nearly every corner. The major obstacles to their massive deployment include reusability and adaptivity. This paper addresses the two crucial problems with one single solution: process inheritance. We discuss what process inheritance is, what mechanisms are needed(More)
Pyrethroid insecticide modulation of the voltage-gated sodium channel (VGSC) is proposed to underlie their effects on neuronal excitability by inhibiting channel inactivation and increasing channel open time. However, some in vitro evidences indicate that target sites other than VGSCs could contribute to pyrethroid disruption of neuronal activity.(More)
Concurrency control has always been one of the most important issues in the design of synchronous groupware systems with fully-replicated architecture. An ideal strategy should be able to support natural and flexible human-to-computer and human-to-human interactions while maintaining the consistency of the system. This paper summarizes previous researches(More)
Friction stir lap welding of 7B04 aluminum alloy was conducted in the present paper, and the effect of welding speed on the defect features and mechanical performance of lap joints was investigated. The results indicate that the hook defect at the advancing side (AS) can reduce the effective thickness of the top sheet, and the sheet thinning level is(More)
