Introduction to Joints00:58

Introduction to Joints

The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no movement.
Hierarchy of Motor Control01:18

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Movement Joints in Buildings01:27

Movement Joints in Buildings

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...
Relative Motion Analysis - Acceleration01:10

Relative Motion Analysis - Acceleration

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...
Migration00:53

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
Multicompartment Models: Overview01:14

Multicompartment Models: Overview

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,...

Area of Science:

  • Complex Systems
  • Transportation Science
  • Computational Social Science

Background:

  • Existing human mobility models (gravity, intervening opportunities, radiation) lack a unified framework.
  • Understanding large-scale human movement patterns is crucial for urban planning and network analysis.

Purpose of the Study:

  • To develop a general and unified continuum approach for modeling human mobility.
  • To derive and validate a novel radiation model for human movement.
  • To explore the underlying mechanisms of complex mobility network formation.

Main Methods:

  • Developed a continuum-based probabilistic framework for human mobility.
  • Derived a new form of the radiation model within this framework.
  • Validated the model using US census commuting data and European mobile phone mobility data.

Main Results:

  • The unified framework encompasses existing mobility models as special cases.
  • The new radiation model accurately predicts observed human mobility fluxes.
  • Demonstrated that complex network topology can emerge from simple stochastic processes.

Conclusions:

  • The proposed continuum approach offers a generalized perspective on human mobility.
  • The derived radiation model provides a powerful tool for analyzing real-world mobility data.
  • Complex mobility networks may be explained by stochastic processes on inhomogeneous spatial landscapes.
