Abstract The proliferation of key marine ecological engineers and carbonate producers often relies on their association with photosymbiotic algae.Evaluating stress responses of these organisms is important to predict their fate under future climate projections.Physiological approaches are limited in their ability to resolve the involved molecular m

Abstract Based on the transformation acoustics methodology, the design principle for achieving an arbitrary shape magnifying lens (ASML) is proposed.Contrary to the previous works, the presented ASML is competent of realizing far-field high resolution images shot glass and breaking the diffraction limit, regardless of the position of the utilized s
