A method for estimating the position and direction of a leader of a set of moving objects
Movement patterns can be identified when studying a group of moving entities such as a group of people, a flock of birds, a school of fish, a convoy of vehicles, among others. In this paper, it is analyzed a pattern, known as leadership.

Effects of Flocks Doping on the Dynamic Mechanical Properties of Shear Thickening Gel
Polymethyl methacrylate (PMMA) was used as the dispersed phase and mold silicone was used as the continuous phase to prepare the shear thickening gel (STG) doped with a certain amount of flocks by rotary stirring.

A flock of a quadratic cone is a partition of a quadratic cone minus its vertex (in 3-dimensional projective space) into plane conics. These objects give rise to a lot of other interesting objects such as translation planes, elation generalized quadrangles, (herds of) ovals, ovoids, regular hyperbolic fibrations, etc. If the associated functions of the

Darkling beetles (Alphitobius diaperinus) and their larvae as potential vectors for the transfer of Campylobacter jejuni and Salmonella enterica serovar paratyphi B variant Java between successive broiler flocks [PDF]
Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive ...

Stochastic modelling of bird flocks – accounting for the cohesiveness of collective motion
Collective behaviour can be difficult to discern because it is not limited to animal aggregations such as flocks of birds and schools of fish wherein individuals spontaneously move in the same way despite the absence of leadership. Insect swarms are, for
