Dimensional Analysis

2020
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Two-dimensional gel electrophoresis (2DGE) is a technique that can resolve thousands of biomolecules from a mixture. This technique involves two distinct separation methods that have been coupled together: isoelectric focusing (IEF) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). This physically separates compounds across two axes of a gel by their isoelectric points (an electrochemical property) and their molecular weights. The procedure in this video covers the main...

Data Reporting and Recording

2023
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...

Triangulation combines observations from multiple viewpoints to reconstruct an organism’s location in space. Calibration provides the spatial reference needed to relate those observations, while synchronized recordings preserve the subject’s position across time. The resulting coordinates allow researchers to analyze movement along the x, y, and z axes rather than inferring depth from a single visual perspective.
Synchronization ensures that observations from different cameras or sensors correspond to the same moment in the behavior. Without temporal alignment, apparent differences between viewpoints could reflect recording delays rather than actual movement. Coordinated timing is therefore important for measuring interactions, comparing positions, and following changes in locomotion or posture across successive observations.
A single viewpoint can obscure movement occurring toward or away from the camera, as well as changes in body position that are difficult to interpret in a flat image. Three-dimensional recordings preserve these spatial relationships, helping researchers examine posture, navigation, locomotion, and interactions with greater precision across individuals or experimental conditions.
Reconstructed coordinates support quantitative measurements of an organism’s location, movement, posture, and spatial pattern over time. Researchers can use these measurements to characterize locomotion, navigation, and interactions, then compare behavioral features across individuals or experimental conditions. This numerical representation also supports more precise analyses than relying only on qualitative visual descriptions.
A typical workflow uses synchronized cameras or sensors positioned to observe the subject from multiple viewpoints. The recording system is calibrated so observations share a spatial reference, after which the subject’s location is reconstructed through triangulation. Researchers then examine the resulting coordinates over time to quantify locomotion, posture, navigation, interactions, or spatial patterns.
Researchers would choose this approach when the behavior depends on depth, changing posture, movement through space, or relationships between individuals. It is especially useful when a single view cannot capture the full movement pattern. The measurements can support comparisons across experimental conditions and help identify behavioral features that remain difficult to detect in two-dimensional video.
In motor control and neuroscience, spatially resolved behavioral measurements connect observable actions with the organization of movement through space. Quantifying posture, locomotion, navigation, and interactions provides a more detailed behavioral outcome for comparing individuals or conditions. These data can therefore strengthen analyses that examine how organisms perform and coordinate behavior in three dimensions.
