- In donor-acceptor mechanically interlocked molecules that exhibit bistability, the relative populations of the translational isomers-present, for example, in a bistable [2] rotaxane, as well as in a couple of bistable [2...
- Nonlinear detection of paleoclimate-variability transitions possibly related to human evolution
[作者:Donges, JF; Donner, RV; Trauth, MH; Marwan, N; Schellnhuber, HJ; Kurths, J,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:20422-20427 , 文章类型: Article,,卷期:2011年108-51]
- Potential paleoclimatic driving mechanisms acting on human evolution present an open problem of cross-disciplinary scientific interest. The analysis of paleoclimate archives encoding the environmental variability in East...
- Economic and energetic analysis of capturing CO(2) from ambient air
[作者:House, KZ; Baclig, AC; Ranjan, M; van Nierop, EA; Wilcox, J; Herzog, HJ,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:20428-20433 , 文章类型: Article,,卷期:2011年108-51]
- Capturing carbon dioxide from the atmosphere ("air capture") in an industrial process has been proposed as an option for stabilizing global CO(2) concentrations. Published analyses suggest these air capture systems may c...
- Electronic dynamics and plasmons of sodium under compression
[作者:Mao, HK; Ding, Y; Xiao, YM; Chow, P; Shu, JF; Lebegue, S; Lazickif, A; Ahuja, R,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:20434-20437 , 文章类型: Article,,卷期:2011年108-51]
- Sodium, which has long been regarded as one of the simplest metals, displays a great deal of structural, optical, and electronic complexities under compression. We compressed pure Na in the body-centered cubic structure ...
- Estimation of 3D shape from image orientations
[作者:Fleming, RW; Holtmann-Rice, D; Bulthoff, HH,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:20438-20443 , 文章类型: Article,,卷期:2011年108-51]
- One of the main functions of vision is to estimate the 3D shape of objects in our environment. Many different visual cues, such as stereopsis, motion parallax, and shading, are thought to be involved. One important cue t...
