Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Hybrid Multiphoton Lithography Scaffolds for Nanoscale Mechanobiological Assessment in Microscale Bone Models

Small, EarlyView.
This work presents a 3D hybrid tissue scaffold inspired by bone, incorporating collagen, fabricated using multiphoton lithography. The mechanical properties of collagen are tunable, and biodegradation allows for time‐dependent changes in geometry. The results demonstrate enhanced osteogenic differentiation of stem cells in our hybrid scaffolds.
