Industrial Biotechnology Conservation Processes: Similarities with Natural Long-Term Preservation of Biological Organisms

Philippe Abdel Sayed, Corinne Scaletta, Lee Ann Laurent-Applegate, Nathalie Hirt-Burri, Laurent Alexis Clément Vannay, Alexis Laurent

Cryopreservation and lyophilization processes are widely used for conservation purposes in the pharmaceutical, biotechnological, and food industries or in medical transplantation. Such processes deal with extremely low temperatures (e.g., -196 degrees C) a ...

Surprise-based model estimation in reinforcement learning: algorithms and brain signatures

Vasiliki Liakoni

Learning how to act and adapting to unexpected changes are remarkable capabilities of humans and other animals. In the absence of a direct recipe to follow in life, behaviour is often guided by rewarding and by surprising events. A positive or a negative o ...

Photonic Nanojet Array for Fast Detection of Single Nanoparticles in a Flow

Martinus Gijs, Matteo Cornaglia, Hui Yang

We detect by optical microscopy Au and fluorescent nanopartides (NPs) during their motion in water based medium, using an array of dielectric microspheres that are patterned in a microwell array template. The Microspheres act as lenses focusing the light o ...

Emerging predictable features of replicated biological invasion fronts

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...
