Early Clinical Experience with a Polymer-Free Biolimus A9 Drug-Coated Stent in DES-Type Patients Who Are Poor Candidates for Prolonged Dual Anti-Platelet Therapy.
Tim Kinnaird,Mehmood Butt,Fairoz Abdul,Khaled Yazji,Ahmed Hailan,Sean Gallagher,Nicholas Ossei-Gerning,Alexander Chase,Anirban Choudhury,David R. Smith,Richard Anderson +10 more
TL;DR: This early experience using polymer-free BA9 drug-coated stents in drug-eluting stent type patients at risk of bleeding are encouraging and rates of disease fitting NICE criteria for DES placement are encouraging.
Proceedings ArticleDOI
Mechanical improvement of the interim LMT/GTM primary surface actuators
TL;DR: In this article, the actuator design of the Large Millimeter Telescope/Gran Telescopio Milimetrico (LMT/GTM) first light program is described.
Proceedings ArticleDOI
Experiences with global laser tracker alignment of the 32.5-m LMT primary surface
Andrea Leon-Huerta,Maribel Lucero Álvarez,Emilio Hernández Rios,Lizeth Cabrera Cuevas,David Castro Santos,Carlos Tzile Torres,Josefina Lázaro Hernández,David M. Gale,Gopal Narayanan,David R. Smith,Grant W. Wilson +10 more
TL;DR: First results using a tracker located near the antenna vertex, and mechanical adjusters in place of actuators are presented, and an RMS error of around 100μm was achieved.
Patent
Tunable metamaterials using microelectromechanical structures
TL;DR: A metamaterial comprises a support medium, such as a planar dielectric substrate and a plurality of resonant circuits supported thereby as discussed by the authors, which can be adjusted using an electrical control signal.
Journal ArticleDOI
Performance of four CVD diamond radiation sensors at high temperature
TL;DR: In this paper, the alpha particle detectors, based on CVD diamond, operate with high charge collection efficiency and energy resolution at temperatures up to 225 ° C. The potential for thermal neutron detection is discussed.
