TL;DR: In this article, the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP.
Journal ArticleDOI
Collaborative care for depression: a cumulative meta-analysis and review of longer-term outcomes.
TL;DR: Collaborative care is more effective than standard care in improving depression outcomes in the short and longer terms.
Journal ArticleDOI
The half-lives of uranium-234 and thorium-230
Hai Cheng,Richard Lawrence Edwards,J.A. Hoff,Christina D. Gallup,David Richards,Yemane Asmerom +5 more
TL;DR: In this article, the authors used high precision thermal ionization mass spectrometric (TIMS) methods to determine the half-life of zircons with concordant 238 U/ 238 U and 230 Th / 238 U atomic ratios.
Journal Article
