Well-to-seismic tie and wavelet phase estimation are close and related steps to link geology and seismic data. Usually these processes are solved separately or alternately, diminishing the quality of the well tying procedure. ...

Introduction: The diagnosis of ankyloglossia, or tongue-tie, and the number of frenotomies performed has increased over 10-fold from 1997 to 2012 in the United States. The sharpest increase has been in neonates. For parents ...
