Poor Understanding of Radiation Profiles in Deep Space Causes Inaccurate Findings and Misleading Conclusions [PDF]
Journal of Biomedical Physics and Engineering, 2019 The radiation environment in deep space, where astronauts are behind the shelter provided by the Earth’s magnetosphere, is a major health concern. Galactic cosmic rays (GCR) and solar particle events (SPE) are two basic sources of space radiation in the ...

From Proxies to System State: Defining Sustainability Management Against Symbolic Progress
Sustainable Development, EarlyView.ABSTRACT Sustainability in management is often measured through scores, ratings, and disclosure narratives that can reward symbolic progress while leaving underlying social‐ecological conditions unchanged. This perspective paper offers a definition of Sustainability Management as how organizations plan, organize, lead, and control (four management ...

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp
Small, EarlyView.Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.
