Comment on the paper "Search for oscillation of the electron-capture decay probability of $^{142}$Pm" at arXiv:0807.0649v1 (2008)

Litvinov, Yu. A., Bosch, F., Winckler, N., Boutin, D., Essel, H. G., Faestermann, T., ...

It is argued that orbital electron-capture decays of neutral $^{142}$Pm atoms implanted into the lattice of a solid (LBNL experiment) do not fulfil the constraints of true two-body beta decays, since...

Hess, S, Heidenreich, S, Ilg, P, Goddard, C, Hess, O

Shear thickening, i.e. the increase of the viscosity with increasing shear rate as it occurs in dense colloidal dispersions and polymeric fluids is an intriguing phenomenon with a considerable...

Estimation of value-of-time using Mixed Logit models (2006)

Hess, S., Bierlaire, M., Polak, J.
