    Hybrid metamaterials combining pentamode lattices and phononic plates

    We propose a design strategy for hybrid metamaterials with alternating phononic plates and pentamode units that produce complete bandgaps for elastic waves. The wave control relies on the simultaneous activation of two scattering mechanisms in the constituent elements. The approach is illustrated by numerical results for a configuration comprising phononic plates with cross-like cavities. We report complete bandgaps of tunable width due to variations of geometric parameters. We show that the wave attenuation performance of the hybrid metamaterials can be further enhanced through implementation of lightweight multiphase material compositions. These give rise to efficient wave attenuation in challenging low-frequency regions. The proposed design strategy is not limited to the analyzed cases alone and can be applied to various designs of phononic plates with cavities, inclusions or slender elements

The studies were conducted in two groups, which differed according to the method of prolonged thromboprophylaxis. It was found that a dosage of 2500 bemiparin once a day within 28 days after discharging patients from the hospital is a more safe and effective method for correcting disturbances in the RASB system than vitamin K antagonists
