Hand stencils with and without narrowed fingers at two new rock art sites in Sulawesi, Indonesia
, 2016 The rock art at Gua Andomo and Gua Lampetia, two newly described sites in the Indonesian island of Sulawesi, is dominated by hand stencils. The Gua Andomo stencils include a variant focused on Sulawesi which involves narrowed fingers.

Rock art, mining and Indigenous well-being in the Lower Hunter Valley: the outlook from Baiame Cave
, 2019 In the Hunter Valley of New South Wales, Australia, a deeply worrying trend hasn emerged where the approval of major mining projects is predicated on the rescinding of areas previously set aside to conserve environmental, including heritage, values. Here,

Deep Underground Science and Engineering, EarlyView.Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

, 2009 Rock art, basically being non-utilitarian, non-textual anthropic markings on natural rock surfaces, was an extremely widespread graphical practice in ancient Egypt. While the apogee of the tradition was definitely the Predynastic Period (mainly fourth millennium BCE), examples date from the late Palaeolithic (c.
