Physical Review E, 2004
Dripping from a faucet is studied, where by cutting diagonally the tip breaks the cylindrical symmetry. We measured long dripping time series recorded with a laser-beam apparatus and continuous change in drop position using a high-speed camera. It is found that the added degree of freedom produces a transversal oscillation of a pending drop, which ...

The direct addition of amine N-H bonds across an unsaturated carbon-carbon linkage gives fast and highly atom-economical access to amines. This review provides an overview of the most effective stereoselective methods using various catalyst systems based on alkali, alkaline earth, and transition metals, as well as enzymatic and organocatalytic ...

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

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 ...

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

SSRN Electronic Journal, 2011 We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such expressive law' we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations) in a repeated public goods experiment.

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.

Angewandte Chemie, 2000
While nonracemic catalysts can generate nonracemic products with or without the nonlinear relationship in enantiomeric excesses between catalysts and products, racemic catalysts inherently give only a racemic mixture of chiral products. Asymmetric catalysts, either in nonracemic or racemic form, can be further evolved into highly activated catalysts ...
