Rhodium is currently the metal of choice to achieve high enantioselectivities in the hydroformylation of a relatively wide variety of alkene substrates. The elucidation of the different steps of the catalytic cycle and the characterization of the resting state, together with the discovery of several types of ligands that are able to provide high ...

Asymmetric Research on Asymmetric Wars
International Studies Review, 2015Great Powers, Small Wars: Asymmetric Conflict Since 1945. By Deriglazova Larisa. Baltimore, MD: Johns Hopkins University Press, 2014. 408 pp., $60 hardcover (ISBN 978-1-421-41412-6). The share of international relations (IR) studies that focus on asymmetric relations does not match the share of international interactions that are asymmetric.

Review of Economic Studies, 2000
The paper deals with asymmetric auctions. ``Asymmetries are often important in contract bidding. Each potential contractor has essentially the same information about the nature of the project but a different opportunity cost of completing it. Whenever some aspect of these differences is common knowledge, beliefs are asymmetric. In major art auctions as

Proceedings of the 24th international conference on Machine learning, 2007
A cost-sensitive extension of boosting, denoted as asymmetric boosting, is presented. Unlike previous proposals, the new algorithm is derived from sound decision-theoretic principles, which exploit the statistical interpretation of boosting to determine a principled extension of the boosting loss.

Physical Review E, 2005
The asymmetric diffusion through conical nanopores is described by the diffusional model. Diffusion is several times faster; when the concentration gradient points from the wide towards the narrow opening of the cone than in the opposite direction. The asymmetric diffusion appears either when the diffusion coefficient depends on the concentration or ...

American Journal of Physical Anthropology, 2002
AbstractThe objective of this study was to examine examples of spondylolysis in which the pattern of separation was clearly asymmetrical, in order to learn more about the process of bone separation that produces this condition. Although the primary focus was on unilateral complete separation, examples of asymmetry represented by incomplete separation ...

Asymmetric extractions for an asymmetric malocclusion
Indian Journal of Oral Health and Research, 2016Some patients with Class II subdivision malocclusions have Class I characteristics on one side and Class II characteristics on the other. The resulting asymmetric occlusal relationship complicates orthodontic treatment. Traditionally, four premolars are extracted in such cases to achieve a bilateral Class I molar relation which needs patient compliance
