Additives and Fillers in Concrete01:29

Additives and Fillers in Concrete

359
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

Gap Junctions01:37

Gap Junctions

57.3K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Gap Junctions01:27

Gap Junctions

9.6K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

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.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Drug Dependence01:17

Drug Dependence

1.7K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Area of Science:

  • Psycholinguistics
  • Developmental Psychology
  • Computational Linguistics

Background:

  • Children's sentence interpretation relies on bottom-up cues.
  • Limited understanding exists on children's use of top-down information from language input.
  • Distributional regularities in language input may guide comprehension.

Purpose of the Study:

  • Investigate incremental interpretation of ambiguous wh-questions in 5- and 6-year-olds.
  • Examine the role of top-down information in children's sentence processing.
  • Determine the developmental emergence of adult-like filler-gap dependency formation.

Main Methods:

  • Visual world eye-tracking experiment with children and adults.
  • Corpus analysis of filler-gap dependency structures in adult and child language.
  • Assessing interpretation of temporarily ambiguous wh-questions.

Main Results:

  • Adults showed active dependency formation at the verb region.
  • 6-year-olds exhibited a bias spill-over effect in the NP region.
  • 5-year-olds showed no such bias; vocabulary size modulated interpretation speed.

Conclusions:

  • Adult-like filler-gap dependency processing emerges around age 6.
  • Distributional regularities may not be utilized by 5-year-olds in real-time comprehension.
  • Language experience and cognitive constraints shape incremental sentence processing development.
