Methodological review and detailed guidance for the life cycle interpretation phase

Alexis Laurent, Xun Liao

Life cycle interpretation is the fourth and last phase of life cycle assessment (LCA). Being a "pivot" phase linking all other phases and the conclusions and recommendations from an LCA study, it represents a challenging task for practitioners, who miss ha ...

Activity induced synchronization: Mutual flocking and chiral self-sorting

Ignacio Pagonabarraga Mora

Synchronization, the temporal coordination of coupled oscillators, allows fireflies to flash in unison, neurons to fire collectively, and human crowds to fall in step on the London millenium bridge. Here, we interpret active (or self-propelled) chiral micr ...
