A dual-band artificial magnetic material and then a dual-band double-negative metamaterial structure based on symmetric spiral resonators are presented. An approximate analytical model is used for the initial design of the proposed structures. The electromagnetic parameters of the proposed metamaterial structure retrieved using an advanced parameter retrieval method based on the causality princ...
IMPORTANCE The current recommendation is for at least 12 months of dual antiplatelet therapy after implantation of a drug-eluting stent. However, the optimal duration of dual antiplatelet therapy with specific types of drug-eluting stents remains unknown.

AbstractThis study aimed at examining the effect of pictorial presentation of vocabulary on EFL students’ retention relying on Dual Coding Theory and Additivity Hypothesis, both of which emphasize the additive effect of images on recall. To that end, 63 students who were in grade three of high school served as the participants of the study. They were randomly divided into three groups of still ...
