Bridging the gap between remotely sensed phenology and the underlying ecophysiological processes: The SWELL model
Published 2025-07-01“…However, current methods for extracting phenological metrics from NDVI data often fail to capture their biological and physiological significance, as they are predominantly based on statistical fitting functions. This study presents SWELL (Simulated Waves of Energy, Light, and Life), a process‐based phenology model that simulates the temporal NDVI profile, from leaf unfolding to dormancy release, based on species‐specific photothermal response functions. …”

Engineered single‐ and multi‐cell chemotaxis pathways in E. coli
Published 2009-06-01“…In addition, by taking advantage of a ‘hitchhiker’ effect in which cells producing the ligand can induce chemotaxis of neighboring cells lacking enzymatic activity, we were able to design a more complex system that functions as a simple microbial consortium. The result effectively introduces a logical ‘AND’ into the system so that the population only swims towards the combined gradients of two attractants.…”
