RESUMEN
We present two cases of patients undergoing secondary surgery due to Baker III and IV contracture, with detailed sonoelastography evaluation before and after the surgery. It is probably the first case where the use of sonoelastography has enabled plane colour-coded analysis of regions with different stiffness (Young moduli, kPa). The obtained results have been compared with applanation tonometry.

We report on the nondestructive observation of Rabi oscillations on the Cs clock transition. The internal atomic state evolution of a dipole-trapped ensemble of cold atoms is inferred from the phase shift of a probe laser beam as measured using a Mach-Zehnder interferometer. We describe a single color as well as a two-color probing scheme. Using the latter, measurements of the collective pseudospin projection of atoms in a superposition of the clock states are performed and the observed spin fluctuations are shown to be close to the standard quantum limit.
