ENHANCING LITHIC ANALYSIS: INTRODUCING 3D-EDGEANGLE AS A SEMI-AUTOMATED 3D DIGITAL METHOD TO SYSTEMATICALLY QUANTIFY STONE TOOL EDGE ANGLE AND DESIGN.

In stone tool studies, the analysis of different technological and typological features is known to provide distinct but interrelated information on the design and use of artefacts.The selection of these features can potentially influence the understanding and reconstruction of past human technological behaviour across time.One feature frequently p

Quantum chaos in Hermitian systems concerns the sensitivity of long-time dynamical evolution to initial conditions.The skin effect discovered recently in non-Hermitian systems reveals the sensitivity to the spatial boundary condition Bosch GIN81AE30G Freezer A++ Rating in White Built-In/Integrated even deep in the bulk.In this Letter, we show that

Rotational head motion is one of the major contributors to brain tissue strain during head impacts, which damages axons and vessels and leads to traumatic brain injury.Helmet technologies have come to market promising enhanced protection against such rotational head motion.We recently introduced novel air-filled viscoelastic cell arrays and showed
