Memory shapes microbial populations [PDF]
PLOS Computational Biology, 2020 AbstractCorrect decision making is fundamental for all living organisms to thrive under environmental changes. The patterns of environmental variation and the quality of available information define the most favourable strategy among multiple options, from randomly adopting a phenotypic state to sensing and reacting to environmental cues.

Shape Memory Photonic Metamaterial [PDF]
Conference on Lasers and Electro-Optics, 2016 We report the first reconfigurable metamaterial based on the shape memory alloy. In the heating cycle structural elements of this metamaterials exhibit a hysteresis-type shape transformation that leads to non-volatile switching of its plasmonic properties.

Materials Today, 2007 Shape-memory polymers are an emerging class of active polymers that have dual-shape capability. They can change their shape in a predefined way from shape A to shape B when exposed to an appropriate stimulus. While shape B is given by the initial processing step, shape A is determined by applying a process called programming.
