Spin-orbit coupling calculations with the two-component normalized elimination of the small component method
TL;DR: A new algorithm for the two-component Normalized Elimination of the Small Component (2cNESC) method is presented and tested in the calculation of spin-orbit (SO) splittings for a series of heavy atoms and their molecules.

A quantitative analysis of calcareous nannofossil bioevents of the Late Cretaceous (Late Cenomanian–Coniacian) Western Interior Seaway and their reliability in established zonation schemes
TL;DR: In this article, the authors analyzed nannofossil assemblages from 8 localities in the Upper Cenomanian-Coniacian strata of central (Colorado and Kansas) and southern (Texas) Western Interior Seaway, USA to produce a new high-resolution biostratigraphic framework for the Greenhorn Formation, Eagle Ford Formation, and basal Austin Chalk.
Journal ArticleDOI
Allocation and architecture in climate governance beyond Kyoto: lessons from interdisciplinary research on target setting.
TL;DR: In this article, the authors identify some of the problems associated with allocation, and its problems interlinked with governance architecture, by examining the case of the allocation of reduction commitments for greenhouse gas emissions in the context of climate governance beyond 2012.
