Early crack detection using dis- tributed fiber optics sensing technique is compared to coda wave interferometry technique and other traditional sensors like LVDT and strain

All these results clearly demonstrate that distributed fiber optic sensors based on Rayleigh sensing technique can detect crack initiation and propagation by monitoring the shape of

These first tests demonstrate that distributed fiber optic sensors based on Rayleigh scattering can be used to detect crack initiation and propagation in pavements, by monitoring

In this section, the authors show how the models presented in ‘Homogenization procedure’ and ‘Micro consistutive models’ sections are combined together in an algorithmic procedure

Altogether, our data establish a critical regulatory role of the cytoplasmic domain of CD28 for its ligand binding and provide new insights on the crosstalk between the TCR-
