Explicit Memories01:27

Explicit Memories

467
Explicit memories, also known as declarative memories, are consciously remembered, recalled, and reported. Studying for a chemistry exam involves material that will become part of explicit memory. There are two types of explicit memory: episodic and semantic.
Episodic memory contains information about personally experienced events and is reported as a story. An example of episodic memory is recalling a birthday celebration. This type of memory includes the what, where, and when of an event, as...

Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Crossing Over

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Crossing Over

6.6K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Area of Science:

  • Mobile communication networks
  • Edge computing
  • Content delivery networks

Background:

  • Next-generation mobile networks will feature increased deployment density and computational power of small base stations (BSs).
  • These BSs form the mobile edge network, a distributed infrastructure supporting edge/fog computing applications.

Purpose of the Study:

  • Propose a novel edge-computing application called explicit caching.
  • Maximize user Quality-of-Experience (QoE) through joint content recommendation, caching, and delivery.

Main Methods:

  • Formulate the explicit caching problem as a joint optimization task.
  • Develop optimal and heuristic algorithms to solve the problem.
  • Derive theoretical performance bounds and conduct simulations.

Main Results:

  • Explicit caching effectively utilizes mobile edge networks for personalized content dissemination.
  • Performance is analyzed considering cache size, BS backhaul, cross-layer information, and user mobility.

Conclusions:

  • Explicit caching offers superior performance over implicit caching schemes.
  • The approach enhances personalized content delivery within mobile edge networks.
