Cohesion01:07

Cohesion

44.9K
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

First Law: Particles in Two-dimensional Equilibrium

14.3K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.

Stability of Equilibrium Configuration

1.0K
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Lattice Centering and Coordination Number

13.8K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Optimal Foraging00:48

Optimal Foraging

11.8K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Coplanar Forces01:25

Coplanar Forces

5.4K
Consider an object upon which multiple forces are acting. If the lines of action of each force lie within the same plane, the system can be considered coplanar. The Cartesian vector form can be used to resolve each force into its respective components. For a coplanar system, the system will be in equilibrium if each component of the resultant force equals zero and the resultant force on the system is zero. If the sum of the forces is not equal to zero, then the object will not be in equilibrium...

Summary

Topological models of self-propelled particles (SPPs) are more stable than metric models for collective animal behavior. Spatially balanced topological interactions, like those in starling flocks, enhance this stability.

Area of Science:

  • Physics
  • Biology
  • Complex Systems

Background:

  • Self-propelled particle (SPP) models are crucial for studying collective animal behavior.
  • Traditional SPP models use metric interactions (fixed radius).
  • Recent experiments suggest bird flocks use topological interactions (fixed number of neighbors).

Purpose of the Study:

  • To compare the stability of metric versus topological SPP models in 3D.
  • To investigate the impact of neighbor selection rules on model stability.
  • To assess the evolutionary advantage of topological interactions against perturbations.

Main Methods:

  • Simulated 3D self-propelled particle models.
  • Compared stability metrics for metric and topological interaction rules.
  • Analyzed spatially balanced topological neighbor selection.

Main Results:

  • Topological SPP models demonstrate greater stability than metric models.
  • Spatially balanced topological rules significantly enhance model stability.
  • The minimal neighbors for stability in balanced models match starling flock observations.

Conclusions:

  • Topological interactions offer a more robust framework for modeling collective animal behavior.
  • Spatially balanced neighbor selection is key to achieving stable collective motion.
  • Findings support the evolutionary advantage of topological interactions in dynamic environments.
