Highly pathogenic avian influenza H5N1 virus clades 2.3.4, 2.3.2, and 7 are the dominant cocirculating H5N1 viruses in poultry in China. However, humans appear to be clinically susceptible mostly to the 2.3.4 virus clade. Here, we demonstrated that A549 cells and human macrophages infected with clade 2.3.4 viruses produced significantly more viruses than those infected with the other two clades...

Background Worsened aortic pathology may adversely affect ventricular function over time. Patients requiring the Ross procedure are at risk for aortopathy including worsened aortic stiffness, and are at risk for left ventricular (LV) dysfunction. Early changes in vascular stiffness can be measured with cardiovascular magnetic resonance imaging (CMR) by pulse wave velocity (PWV). Likewise, decre...

In the ever-changing business world, appropriate vendor selection can be crucial in supply chain management. Dynamic models supporting vendors with time axis are not always crisp; rather they involve a high degree of fuzziness and uncertainty in real life situations. This paper proposes a dynamic model with uncertainty based on Fuzzy AHP for long-term strategic vendor selection problems. The se...

(Hetero)aryl bis-acid chlorides and terminal alkynes, or likewise acid chlorides and terminal dialkynes, and ethyl 2-mercaptoacetate can be reacted to give highly luminescent symmetrical terthiophenes and quinquethiophenes in the sense of a consecutive pseudo-five-component reaction in good to excellent yields. Further functionalization of the obtained oligomers can be readily achieved by halog...

We show that the generalized variant of formal systems where the underlying equational specifications are membership equational theories, and where the rules are conditional and can have equations, memberships and rewrites in the conditions is reflective. We also show that membership equational logic, many-sorted equational logic, and Horn logic with equality are likewise reflective. These resu...
