We aimed to describe the mood states and related factors in a sample of adolescents in the city of Barcelona (Spain). Methods: We administered a health survey to a sample of 2,727 students from public,...

We study the impact of quenched random potentials and torques on scalar active matter. Microscopic simulations reveal that motility-induced phase separation is replaced in two dimensions by an asymptotically homogeneous with anomalous long-ranged correlations nonvanishing steady-state currents. Using a combination phenomenological models field-theoretical treatment, we show existence lower-crit...
