Mean free path and Mean free time

Consider the gas molecules in a cylinder. They move in a random motion as they collide with each other and change speed and direction. The average of all the path lengths between collisions is known as the "mean free path." The mean free path varies inversely with the density of the molecules because when there are more molecules inside a volume, they have a greater chance of colliding with each other, thus reducing the mean free path. Additionally, the mean free path is inversely related to...

Consider the two thermodynamic processes involving an ideal gas that are represented by paths AC and ABC in Figure 1: In the first process for path A to C, the gas is kept at constant temperature T. It undergoes an expansion from volume V1 to V2. The work done by an ideal gas is expressed as Substituting for pressure as nRT/V from the ideal gas equation and integrating the terms, the work done by an ideal gas at constant temperature is obtained as In the second process, for path A to B, the...

Mitochondrial visualization and analysis from mammalian brain tissue is a challenging task. Here, we describe how three dimensional (3D) reconstruction analysis from the serial block-face scanning electron microscopy (SBFSEM) can be used to gain insights on the morphological and volumetric analysis of this critical energy generating organelle.

This paper describes two novel ImageJ plugins for 'Clock Scan' image analysis. These plugins expand the functionality of the original visual basic 6 program and, most importantly, make the program available to a large research community by bundling it with the ImageJ free image analysis software package.
FAQs
Fixation timing shows how long a viewer remains engaged with particular parts of a stimulus, while the order of those fixations indicates how attention unfolds. Longer dwell times may identify areas receiving sustained processing, and earlier or repeated visits can reveal their position in the viewing sequence. Together, these measures help relate gaze behavior to visual information processing.
Saccades connect successive fixations and show how gaze shifts across a scene, image, or interface. Examining transitions between defined areas of interest can identify common movement paths and the relationships among viewed elements. This information helps researchers examine whether attention progresses in an organized sequence or moves between visually relevant regions during a task.
Comparing scan paths allows researchers to examine differences in viewing order, dwell time, and movement between areas of interest. These patterns can show how people allocate attention while reading, searching for visual information, or interpreting a scene. In behavior research, the comparison helps connect observable gaze sequences with variation in processing strategies and decision-related viewing.
A typical workflow begins by presenting a scene, image, interface, or other stimulus while eye-tracking technology records gaze position over time. Researchers then identify fixations and the saccades connecting them, examine viewing order and dwell time, and evaluate transitions among areas of interest. The resulting scan path supports analysis of attention and visual behavior.
Researchers can use the method when the sequence of visual attention matters, including studies of reading, visual search, user interaction, learning, and responses to social or environmental cues. It is especially useful when overall viewing time alone cannot show which elements attracted attention, how gaze moved among them, or how visual processing related to behavior.
Scan paths can provide evidence about how viewers allocate attention, process visual information, and make decisions. In interface or user-interaction studies, they can show movement among relevant regions; in learning or reading studies, they can describe viewing sequences and dwell times. For social or environmental stimuli, the patterns can characterize responses to visual cues.
