Affinity propagation clustering (AP) has two limitations: it is hard to know what value of parameter 'preference' can yield an optimal clustering solution, and oscillations cannot be eliminated automatically if occur. The adaptive AP method is proposed to overcome these limitations, including adaptive scanning of preferences to search space of the number of(More)
BACKGROUND Studies from the balloon angioplasty and bare metal stent eras have demonstrated that coronary artery bypass grafting (CABG) is cost-effective compared with percutaneous coronary intervention (PCI) for patients undergoing multivessel coronary revascularization-particularly among patients with complex coronary artery disease or diabetes mellitus.(More)
BACKGROUND Atherothrombosis is the underlying cause of cardiovascular, cerebrovascular, and peripheral arterial disease and is the leading cause of death in the industrialized world. The objectives of the present study are (1) to examine the annual costs associated with vascular events and interventions that require hospitalization, as well as long-term(More)
BACKGROUND Peripheral artery disease (PAD) is common and imposes a high risk of major systemic and limb ischemic events. The REduction of Atherothrombosis for Continued Health (REACH) Registry is an international prospective registry of patients at risk of atherothrombosis caused by established arterial disease or the presence of ≥3 atherothrombotic risk(More)
This work focused on the lactic acid production from acidogenic fermentation of fruit and vegetable wastes treatment. A long term completely stirred tank reactor (CSTR) lasting for 50 days was operated at organic loading rate (OLR) of 11 gVS/(L d) and sludge retention time (SRT) of 3 days with pH controlled at 4.0 (1-24 day) and 5.0 (25-50 day). The results(More)
BACKGROUND Previous studies have shown that among patients undergoing multivessel revascularization, coronary-artery bypass grafting (CABG), as compared with percutaneous coronary intervention (PCI) either by means of balloon angioplasty or with the use of bare-metal stents, results in greater relief from angina and improved quality of life. The effect of(More)
BACKGROUND Despite limited evidence from randomized trials, perioperative treatment with beta-blockers is now widely advocated. We assessed the use of perioperative beta-blockers and their association with in-hospital mortality in routine clinical practice. METHODS We conducted a retrospective cohort study of patients 18 years of age or older who(More)
CONTEXT Cardiovascular complications following major noncardiac surgery are an important source of perioperative morbidity and mortality. Although lipid-lowering medications are considered a key component in the primary and secondary prevention of cardiovascular disease, their potential benefit during the perioperative period is uncertain. OBJECTIVE To(More)
OBJECTIVES This study sought to compare health status and quality-of-life outcomes for patients with severe aortic stenosis (AS) and high surgical risk treated with either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (AVR). BACKGROUND For high-risk patients with severe AS, TAVR has been shown to result in similar(More)
Clay-humic complexes are commonly distributed in natural environments. They play very important roles in regulating the transport and retention of hydrophobic organic contaminants in soils and sediments. This study examined the structural changes of humic acid (HA) after adsorption by clay minerals and determined phenanthrene sorption by clay-humic(More)
