Abstract A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca.8.2 ka.High frequency, large amplitude variations in carbon isotopes during the Vehicle Lights 8.2 ka event, couple
Architected composite metastructures can exhibit a subwavelength ultrawide bandgap (BG) with prominent emerging applications in the structural vibration and noise control and, elastic wave manipulation.The present study implemented both forward and inverse design methods based on numerical simulations and machine learning (ML) methods, respectively
