Unretouched triangular microlithic projectile points have been identified from their impact traces in the oldest occupation layers of the Obi-Rakhmat site in Uzbekistan, dating to 80,000 years ago.

Abstract: A fast linear solver for electromagnetic finite element analysis with electric circuit using a deflation technique with Proper Orthogonal Decomposition (POD) is discussed. The authors have ...

Abstract: This study proposes a universal shape sensing strategy to reconstruct the shape of structures with complex geometries by introducing solid elements into the inverse finite element method ...

The right amount of oxygen being present when the Earth’s core was formed meant that there was sufficient phosphorus and nitrogen available in the mantle and crust. This means the Earth was the ...
