Phase Transitions

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Phase Transitions: Sublimation and Deposition

Phase Transitions: Sublimation and Deposition

Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Common Ion Effect

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Properties of Transition Metals

Properties of Transition Metals

Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Fates of Pyruvate

Fates of Pyruvate

Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Cooperative Allosteric Transitions

Cooperative Allosteric Transitions

Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Summary

This summary is machine-generated.

Gestalt psychology's common fate extends beyond motion to include coordinated changes in luminance and size. Dynamic motion is the strongest visual grouping factor, followed by dynamic size and luminance, impacting data visualization design.

Area of Science:

Cognitive Psychology
Human-Computer Interaction
Data Visualization

Background:

Gestalt psychology's Law of Common Fate posits that objects moving together are perceived as a group.
This study expands the concept of common fate beyond motion to include dynamic changes in luminance and size.

Purpose of the Study:

To investigate how coordinated changes in luminance and size influence visual grouping, extending the Law of Common Fate.
To rank the perceptual grouping strengths of various static and dynamic visual factors.

Main Methods:

A crowdsourced graphical perception study involving perceptual judgments on visual grouping.
Experiments utilized static and dynamic visual factors (position, size, luminance) in conflicting scenarios.
A follow-up experiment used an animated scatterplot and a thematic map for ecological validity.

Main Results:

Motion was the strongest visual grouping factor, followed by dynamic luminance, dynamic size, and static luminance.
Dynamic size was a stronger grouping cue than dynamic luminance or position.
Dynamic luminance was a stronger grouping cue than static size.

Conclusions:

The relative strength of visual grouping factors in data visualization depends on visualization characteristics and data.
Findings offer design implications for effective animated transitions in data visualization.
Coordinated changes in luminance and size are significant contributors to the perception of common fate.
