Truss structures composed of members that work exclusively in tension or compression appear several problems science and engineering, e.g., the study resisting mechanisms masonry structures, as well design spider web-inspired web structures. This generalizes previous results on existence cable webs are able to support assigned sets nodal forces under tension. We extend such a problem limit anal...

In 1995, Allen Fisher published a poem entitled ‘Mummers’ Strut’ in an issue of the magazine West Coast Line,[1] accompanied by a statement of poetics. The poem is organised into twentyseven short numbered sections, mostly in couplets, ranging from two to twenty lines in length. The predominant impression is of a fragmented discourse that is hard to read as constructing a consistent speaking vo...

Struts as an important structure in the combustion chamber of hypersonic flight vehicles to inject fuel into main flow face a severe thermal environment. Transpiration cooling is considered potential method provide protection for struts. This paper presents numerical investigation on transpiration strut based Darcy–Forchheimer model and local non-equilibrium analyzes mechanism cooling. A coolan...

BACKGROUND Peri-stent coronary evaginations may disturb flow and have been proposed as possible risk factor for late stent thrombosis. We describe incidence, predictors, and possible mechanisms of coronary evaginations 12 months after implantation of bioresorbable vascular scaffolds (BVS). METHODS AND RESULTS One hundred and two BVS implanted in 90 patients (age 63 ± 13 years, 71 males, 14 di...

A major consequence of stent implantation is restenosis that occurs due to neointimal formation. This patho-physiologic process of tissue growth may not be completely eliminated. Recent evidence suggests that there are several factors such as geometry and size of vessel, and stent design that alter hemodynamic parameters, including local wall shear stress distributions, all of which influence t...

AIMS The first generation of the everolimus-eluting bioresorbable vascular scaffold (BVS 1.0) showed an angiographic late loss higher than the metallic everolimus-eluting stent Xience V due to scaffold shrinkage. The new generation (BVS 1.1) presents a different design and manufacturing process than the BVS 1.0. This study sought to evaluate the differences in late shrinkage, neointimal respons...

AIMS Optimizing stent deployment is important for both acute- and long-term outcomes. High-pressure balloon inflation is the standard for coronary stent implantation. However, there is no standardized inflation protocol. We hypothesized that prolonged high-pressure balloon inflation until stabilization of inflation pressure is superior to a rapid inflation/deflation sequence for both stent expa...
