At present, workflow management systems have not sufficiently dealt with the issues of time, involving time modelling at build-time and time management at run-time. They are lack of the ability to support the checking of temporal constraints at run-time. Although some approaches have been devised to tackle this problem, they are limited to a single workflow(More)
A workflow specification is a formal description of business processes in the real world. Its correctness is critical to the workflow execution and hence the realisation of business objectives. In addition to structural and temporal constraints, resource constraints are also implied in workflow specifications. Therefore, they should be analysed to ensure(More)
BACKGROUND The most practical serum biomarker AFP is negative in 80% patients with small tumor in the early stage of primary hepatocellular carcinoma (PHC). OBJECTIVE To investigate significance of combined tests of serum golgi glycoprotein 73 (GP73), lens culinaris agglutinin-reactive alpha-fetoprotein (AFP-L3), glypican 3 (GPC3), des-gamma-carboxy(More)
BACKGROUND p21-activated protein kinase (PAK) 6 is a serine-threonine kinase belonging to the PAK family. Previous studies have indicated that abnormal expressions of PAK1, PAK2, and PAK5 played critical roles in hepatocellular carcinoma (HCC). Recent studies suggested that deregulation of PAK6 expression played an important role in oncogenesis. To explore(More)
Objectives: Impairments in interpersonal relationships in depression present as irritability, pessimism, and withdrawal, and play an important role in the onset and maintenance of the disorder. However, we know little about the neurological causes of this impaired interpersonal function. This study used the event-related brain potential (ERP) version of the(More)
Extrahepatic bile duct stones, a relatively common disease, mainly occurs in the bile duct, commonly hepatic duct stone. Extrahepatic bile duct stones can be divided into primary and secondary. Primary accounts for the majority, which refers to primary bile duct stones, mainly bile pigment stones or mixed stones (Figure 1); secondary refers to gallbladder(More)
