Challenges and ongoing initiatives towards better integrated EU scientific advice by Iordanis Gravanis, Michael Berntgen, Spiros Vamvakas, Pierre Demolis, Paolo Foggi

“…There are multiple avenues for seeking scientific advice in the EU with partially overlapping scope which creates room for divergence and contradictions; simplification and better integration among them could help harmonize EU regulators’ requirements. Interaction with other decision makers providing advice along the lifecycle of medicines and other healthcare solutions reduces development uncertainties. …”

An Electrostatically Actuated MEMS Arch Band-Pass Filter by Hassen M. Ouakad

“…The arches are actuated by a DC electrostatic load superimposed to an AC harmonic load. The dynamic response of the arch is studied analytically using a Galerkin-based reduced-order model when excited near its fundamental and third natural frequencies. …”
