Multi-scale Analysis of MEMS Sensors Subject to Drop Impacts
Sensors, 2007 The effect of accidental drops on MEMS sensors are examined within the frame-work of a multi-scale finite element approach. With specific reference to a polysilicon MEMSaccelerometer supported by a naked die, the analysis is decoupled into macro-scale ...

Stability Test of PACAP in Eye Drops [PDF]
Journal of Molecular Neuroscience, 2020 AbstractPACAP is a neuropeptide with widespread distribution and diverse biological functions. It has strong cytoprotective effects mediated mainly through specific PAC1 receptors. Experimental data show protective effects of PACAP in the retina and cornea in several pathological conditions.

A Preliminary Assessment of an FBG-Based Hard Landing Monitoring System
Photonics, 2021 In aeronautics, hard landing is a critical condition as the aircraft approaches the runway with a vertical velocity that exceeds 2 m/s. Beyond that level, the energy that should be then absorbed by the whole structure could cause severe damage to the ...
