Contact Angle01:13

Contact Angle

21.8K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Contact-dependent Signaling01:19

Contact-dependent Signaling

47.6K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
Gap Junctions
In animal cells, gap junctions are formed...

How Data are Classified: Categorical Data

44.8K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

How Data are Classified: Numerical Data

38.1K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Data Validation01:15

Data Validation

2.1K
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

Area of Science:

  • Epidemiology
  • Mathematical Biology
  • Infectious Disease Modeling

Background:

  • Global health discussions emphasize revamping epidemic control and prevention strategies.
  • Integrating diverse data sources is crucial for enhancing epidemic preparedness.
  • Individual-level host-pathogen dynamics can inform population-level epidemic phenomena.

Purpose of the Study:

  • To propose and validate a multiscale approach for epidemic modeling.
  • To demonstrate how within-host pathogen dynamics can reproduce population-level observations.
  • To investigate the role of individual differences and population structure in disease transmission.

Main Methods:

  • Formulated mathematical models of pathogen infection dynamics using experimental data.
  • Simulated pathogen transmission parameters mechanistically.
  • Embedded models within an age-specific contact network framework.
  • Illustrated the approach using Ebola virus (EBOV) as an example.

Main Results:

  • A within-host infection model successfully reproduced EBOV transmission parameters from population data.
  • Population age structure and contact patterns were effectively modeled using a network-generating algorithm.
  • EBOV's reproduction number showed age-group heterogeneity, highlighting the need for contact pattern adjustments.
  • Mass vaccination strategies demonstrated significant epidemic size reduction, even with low coverage (33%).

Conclusions:

  • Within-host infection data can capture key pathogen transmission parameters, improving epidemic preparedness.
  • Age-specific contact networks allow for modeling populations without exhaustive data.
  • The multiscale framework offers opportunities to explore multilevel aspects of infectious disease epidemics.
