Protein Complex Assembly02:41

Protein Complex Assembly

16.8K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Spindle Assembly02:50

Spindle Assembly

4.3K
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...

Oligosaccharide Assembly01:24

Oligosaccharide Assembly

3.7K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
Multiple sugar molecules that may or may...

The Fossil Record02:56

The Fossil Record

27.5K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Assembly of Cytoskeletal Filaments01:18

Assembly of Cytoskeletal Filaments

27.9K
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...

Area of Science:

  • Human-Computer Interaction
  • Biometric Sensing
  • Cognitive Load Assessment

Background:

  • Digital assembly instructions can be improved with interactive elements.
  • Gaze-tracking offers potential for hands-free control and data collection.
  • Pupil dilation is a known indicator of cognitive effort and task engagement.

Purpose of the Study:

  • To evaluate a gaze-interactive digital assembly instruction system.
  • To assess the usability of gaze control for children in a realistic setting.
  • To concurrently log pupil data and analyze its correlation with task progression.

Main Methods:

  • Developed a gaze-interactive digital assembly instruction system with head-based controls.
  • Conducted a user study with 72 children in LEGO toy stores.
  • Collected data on usability, view-times, pupil dilation, and head movements.

Main Results:

  • 64 out of 72 children found the system immediately usable.
  • Pupil dilation decreased during building, but increased when backtracking (indicating effort).
  • Gaze-tracking enabled robust interaction and non-intrusive data collection in a real-world environment.

Conclusions:

  • Gaze-tracking technology is effective for interactive assembly instructions and pupil data logging.
  • Pupil data, despite potential confounding factors, can offer insights into cognitive load during tasks.
  • Future applications can leverage this technology for enhanced user understanding and adaptive interfaces.
