this last case that is depicted : it is quite clear that the Peierls transition is not a metal-insulator transition : the wave vector of the modulation is
A table of best values for the K shell relative transition probabilities has been formed from recent measurements.. The values are not in agreement with those reported in the
— Ultrasonic measurements in CBOOA near the smectic A-nematic transition show the occurrence of critical absorption and therefore support the second order nature of the
Finally we estimate from the above that the glass transition is well described in the framework of usual scaling theories as a succession of aborted second
The ratio between the RMSEP obtained from the validation and training groups and the RER calculated from the valida- tion group were used to compare the quality of PLSR results
temperature, where fluctuation efTects are expected to be small, our results are fully consistent with a low frequency conventional Drude response (with an additional
