WHAT ONCE WAS SHALL BE AGAIN: PALAEOLITHIC BIFACES AT THE NEOLITHIC SITE OF GIV'AT RABI EAST
Oxford Journal of Archaeology, EarlyView.Summary Giv'at Rabi East is a Pre‐Pottery Neolithic B site located in northern Israel, interpreted as a flint workshop. One area has been spatially identified as a ‘biface locality’; it is characterized by the presence of finished axes and preforms alongside débitage. Interestingly, Acheulean bifaces have also been recovered from this area.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like
