In 2000, the thematic network ENTRANSFOOD was launched to assess four different topics that are all related to the testing or assessment of food containing or produced from genetically modified...
Striking Oil: Another Puzzle (2003)
Driesprong, G., Jacobsen, B., Maat, B.
We find that changes in oil prices strongly predict future stock market returns in many countries in the world. In our thirty year sample of monthly data for developed stock markets, we find...
An Optical Ultra-High-Resolution Cross-dispersed Echelle Spectrograph with Adaptive Optics (2002)
Ge, Jian, Angel, J. R. P., Jacobsen, B., Woolf, N., Fugate, R. Q., Black, J. H.
A prototype cross-dispersed optical echelle spectrograph of very high resolution has been designed and built at Steward Observatory and tested at the Starfire Optical Range (SOR) 1.5 m telescope. It...
Simultaneous measurements of propagation characteristics on noncontiguous HF channels (2001)
Smith, O. J., Angling, M. J., Cannon, P. S., Jodalen, V., Jacobsen, B., Gronnerud, O. K.
An experiment to investigate the relationship between channel characteristics on noncontiguous HF channels has been run on an HF path in Norway. Initial results from a limited 3 kHz bandwidth data...
(In)accuracy of a political stockmarket: the influence of common value structures (2000)
Jacobsen, B., Potters, J.J.M., Wit, J.
This paper presents the results of a political stock market in the Netherlands: PAM94. The exchange covered three consecutive elections, allowing trade on five different markets. The predictions at...
Konstantinidis, N P, Calvet, D, Jacobsen, B, Kim, H, Litke, A M, Taylor, G
Exclusive reconstruction of $B^{**}\rightarrow B\pi^{\pm}$, with a mass resolution of only a few $MeV/c^2$, is an important tool for the study of $B^{**}$ spectroscopy. Therefore, with the \Aleph\...
