Optimal Foraging00:48

Optimal Foraging

13.2K
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.

Mechanistic Models: Compartment Models in Individual and Population Analysis

202
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Mechanistic Models: Overview of Compartment Models

297
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Multicompartment Models: Overview

441
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Distribution Reliability and Automation

439
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Protein Networks02:26

Protein Networks

4.4K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Area of Science:

  • Food Science
  • Public Health
  • Computer Simulation

Background:

  • The food supply chain is vulnerable to bioterrorist attacks.
  • Current crisis management lacks integrated response programs for food defense.
  • Computer simulations offer valuable training and analysis tools for various industries.

Purpose of the Study:

  • To describe an agent-based simulation for food defense training and analysis.
  • To evaluate the impact of decision-making on economic and public health outcomes during a food supply bioterrorist attack.
  • To identify key learning points for improving food defense strategies.

Main Methods:

  • Collected production, consumption, morbidity/mortality, and recall cost data.
  • Developed a data-driven, agent-based simulation model.
  • Conducted a case study with 40 industry representatives making simulated recall and testing decisions.

Main Results:

  • Simulated decisions led to over 76,000 illnesses and 45 deaths, with $132 million in recall costs.
  • A no-intervention scenario estimated 91,000 illnesses and 54 deaths, showing improved outcomes from player decisions.
  • Key learnings included the importance of communication, differentiating food safety from food defense, and enhancing security protocols.
