The disease Rhizoctonia leaf and sheath spot (RLSS), caused by zeae Voorhees, is problematic in ultradwarf bermudagrass (UDBG) [Cynodon dactylon (L.) Pers. × C. transvaalensis (Burtt-Davy)] putting greens. Typically, RLSS symptoms are most severe late summer appear as frog-eye patches 10 to 40 cm diameter. In UDBG, often called “mini-ring” because of the small brown rings that produced when pro...

We report both numerical and experimental constructions of a tunnel structure with low-frequency low-reflection bidirectional sound insulation (BSI). The designed was constructed from pair lossy acoustic metasurfaces (AMs), which consists six ultrathin coiled unit cells, attached on sides. Based the generalized Snell?s law phase modulations for AMs, BSI based reflections blind areas created by ...
