Error detection of structured workflow definition using set constraint system
No full textA workflow definition containing errors might cause serious problems for an enterprise especially when it involves mission critical business processes or inter-organizational interaction. So workflow definitions should be defined in a strict and rigorous way. In this paper, we develop a workflow definition language and analysis methods for the language to support strict and rigorous workflow definitions. Faults or mistakes causing communication deadlock, access conflicts, and improper exception specification in workflow definitions can be detected and notified automatically using the methods. The proposed workflow definition language borrows structured constructs of conventional programming languages because many good features of conventional programming languages also can be used effectively in expressing workflow processes. With slight modifications and scope restrictions, the developed analysis techniques in this paper can be used in any workflow definition languages and they can help workflow designers define workflow processes in much more safe and reliable manner
Handoff effect on CDMA forward link capacity
No full textIn this letter, an analysis on CDMA forward link capacity with hard and soft handoffs, when a handoff decision is based on filtered pilot signal strengths, is provided. For the soft handoff, capacity based on three different power allocation schemes is investigated: equal power, equal signal to interference ratio and selection diversity. Contrary to previous results that soft handoff provides a capacity decrease in the CDMA forward link, it is concluded that soft handoff mitigates capacity loss due to filtering through diversity gain, and may in fact provide higher capacity

No full textAtherosclerotic cardiovascular disease is a major complication of diabetes, whose progression is significantly accelerated by hyperglycemia. Imeglimin, a novel oral antidiabetic agent, has demonstrated efficacy in glucose control; however, its role in diabetes-related cardiovascular complications has not yet been fully explored. This study aimed to investigate the effects of imeglimin on foam cell formation and atherosclerosis in the context of diabetes. THP-1 macrophages were treated with oxidized low-density lipoprotein (LDL) and high glucose to induce foam cell formation in vitro. Additionally, ApoE−/− mice with streptozotocin-induced diabetes were used to determine the effects of imeglimin in vivo by analyzing metabolic parameters and atherosclerotic plaque formation. Imeglimin inhibited macrophage-derived foam cell formation by promoting the expression of ATP-binding cassette transporters (ABC) A1 and ABCG1 and downregulating the expression of CD36. The effects of imeglimin on ABCG1 and CD36 expression regulation was mediated by AMPK. In diabetic ApoE−/− mice, imeglimin reduced the atherosclerotic plaque area, decreased fasting glucose and LDL cholesterol levels, and upregulated ABCG1 expression in the liver and aorta. These findings suggest that imeglimin may have a preventive effect on foam cell formation and a therapeutic role in atherosclerosis progression in diabetic conditions
