Foreign Outsourcing: Economic Implications and Policy Responses [PDF]
, 2004 Foreign outsourcing--the importing of some intermediate product (i.e., a portion of a final product or some good or service needed to produce a final product) that was once produced domestically--is not a new phenomenon, nor is it one that is ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Advanced Functional Materials, EarlyView.Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
