Animals in groups touch each other, move in paths that cross, and interact in complex ways.
Current video tracking methods sometimes switch identities of unmarked individuals during …

Understanding of animal collectives is limited by the ability to track each individual. We describe
an algorithm and software that extract all trajectories from video, with high identification …

The striking patterns of collective animal behavior, including ant trails, bird flocks, and fish
schools, can result from local interactions among animals without centralized control. Several …

A variety of simple models has been proposed to understand the collective motion of animals.
These models can be insightful but may lack important elements necessary to predict the …

We investigate the transient times for the onset of control of steady states by time-delayed
feedback. The optimization of control by minimizing the transient time before control becomes …

Oxylipins are potent biological mediators requiring strict control, but how they are removed
en masse during infection and inflammation is unknown. Here we show that …

The propagation characteristics of a new coupled fin line structure, with asymetrical,
rectangular, top and bottom housings, is evaluated by using the modal analysis technique. The …

Majority-voting or averaging the estimations made by the individuals in a collective are simple
rules that can effectively aggregate knowledge under some ideal conditions. However, …

Eicosanoids are important mediators of fever, pain, and inflammation that modulate cell
signaling during acute and chronic disease. We show by using lipidomics that thrombin-…

Activated platelets generate an eicosanoid proposed to be 8-hydroxy-9,10-dioxolane A3 (DXA
3 ). Herein, we demonstrate that significant amounts of DXA 3 are rapidly attached to …
