Abstract Sedimentary structures deposited from dilute pyroclastic currents are largely dominated by the products of metre‐scale dune bedforms containing backset lamination. Since first seminal works in 1970s, vast majority literature called these antidunes and chutes‐and‐pools. This consensus led to a loose terminology, either as descriptive terms for beds or an interpretation hydrodynamic cond...

Although whiplash is typically classified as a minor injury, the economic cost ofwhiplash has been estimated at roughly $4.5 billion per year in the United States. International research efforts have included computational modeling, crash reconstructions, biomechanical testing of animals and human cadavers, and experimental rear impact tests using both anthropomorphic dummies and human subjects...

The study aims to contribute to discussions for the standardization of BioRID-II dummies as an evaluation test tool, which is underway at the UN ECE/WP29/GRSP Head Restraint gtr Informal Meeting. Since it is important that as a test tool, BioRID-II be able to ensure a high repeatability and reproducibility, BioRID-II’s response variations in calibration and sled tests be examined using the foll...
