Abstract: Abstract Structural model updating (SMU) by sensitivity analysis is a reliable and successful approach to adjusting finite element models of real structures by modal data. However, some challenging issues, including the incompleteness of measured modal… read more here.

Abstract: Summary Multifocal IOLs are more often responsible for lower contrast sensitivity (CS) than monofocal IOLs, especially in mesopic light conditions. Thus, multifocal IOLs are contraindicated in many ocular diseases, which are characterized by decreased contrast… read more here.
