Protein complexes called tight junctions hold adjacent cells of an epithelial monolayer tightly together, creating a physical barrier between apical and basolateral membranes. Vermeer et al. show that in human airway epithelia, tight junctions keep the growth factor heregulin, and its receptor, erbB2, apically and ...

A break in both strands of the DNA double helix is potentially very dangerous for organisms because the free ends can recombine inappropriately with other parts of the genome and cause substantial damage. Eukaryotic cells sense and attempt to repair such breaks very rapidly, through the recruitment of DNA repair proteins to the sites of damage, forming

Damage detection with auxiliary subsystems [PDF]
, 2008 The small sensitivity to local variations of mechanical characteristics turns out to be the major limit of indirect identification techniques based on frequency response measurements. To overcome this limit, the use of sensitivity enhancement techniques has recently proposed: the monitored structure is coupled to an auxiliary system, the constitutive ...

Damage Detection in Flexible Structures
Journal of Sound and Vibration, 1993Abstract A method is developed for the detection of the existence and location of structural damage. Structural damage is considered to be at the macroscopic level. The detection is carried out in two parts. In the first part, the eigensolution of the structure is identified using a modal parameter identification technique and the system response ...

Damage detection using generic elements: Part II. Damage detection
Computers & Structures, 2003This paper proposes the use of generic elements in damage detection, based on the use of an updated baseline finite element model, modal sensitivities and changes in the measured modal quantities arising from structural damage. A companion paper presented the fundamental theory of model updating and generic element or substructure parameterisation. The

Damage detection in a suspension bridge model using the interpolation damage detection method
2012Herein the feasibility of a damage detection and localization method (the Interpolation Damage Detection Method) is investigated for damage detection of long span suspension bridges. Based on the response induced by wind loading, a 'signature' of the structure in the intact state is obtained in terms of the power spectral densities of responses along ...

Creep is an important factor in designing metal structures used at elevated temperatures. Dislocations again play a key role in deformation at elevated temperatures; they multiply, slip, form voids and subgrain boundaries, and annihilate. This chapter shows that the shear wave attenuation is highly sensitive to the dislocation activity in crept metals ...
