Stage and continuum approaches in prehistoric biface production: A North American perspective.
PLoS ONE, 2017 North American lithic analysis often assigns biface preforms to discrete, successive stages defined in Callahan's influential study. Yet recent research questions the stage concept, emphasizing instead a continuous view of the reduction process.

From Rigid to Soft Robotic Approaches for Neuroendoscopy
Advanced Robotics Research, EarlyView.Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
