The earliest use of the (icosahedral) geodesic grid in geophysical modeling dates back to 1968 and the work by Sadourny, Arakawa, and Mintz and Williamson. Later work expanded on this base.
Construction
A geodesic grid is... |

https://en.wikipedia.org/wiki/Cisco%20Security%20Agent | Cisco Security Agent (CSA) was an endpoint intrusion prevention system software system made originally by Okena (formerly named StormWatch Agent), which was bought by Cisco Systems in 2003.
The software is rule-based, and it examines system activities and network traffic, determining which behaviours are normal and wh... |

https://en.wikipedia.org/wiki/Microtentacle | Microtentacles are microtubule-based membrane protrusions that occur in detached cells. They were discovered by scientists studying metastatic breast cancer cells at the University of Maryland, Baltimore.
These novel structures are distinct from classical actin based extensions of adherent cells, persist for days in b... |

Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses a... |
https://en.wikipedia.org/wiki/Diamond-like%20carbon | Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties.
DLC exists in seven different forms. All seven contain significant amounts of sp3 hybridized carbon ... |
https://en.wikipedia.org/wiki/Exchange%20spring%20media | Exchange spring media (also exchange coupled composite media or ECC) is a magnetic storage technology for hard disk drives that allows to increase the storage density in magnetic recording. The idea, proposed in 2004 by Suess et al., is that the recording media consists of exchange coupled soft and hard magnetic layers... |
https://en.wikipedia.org/wiki/Polymerase%20cycling%20assembly | Polymerase cycling assembly (or PCA, also known as Assembly PCR) is a method for the assembly of large DNA oligonucleotides from shorter fragments. The process uses the same technology as PCR, but takes advantage of DNA hybridization and annealing as well as DNA polymerase to amplify a complete sequence of DNA in a pr... |
https://en.wikipedia.org/wiki/Conservation%20of%20mass | In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so the quantity can neither be added nor be removed. Therefore, ... |
https://en.wikipedia.org/wiki/Non-linear%20preferential%20attachment | In network science, preferential attachment means that nodes of a network tend to connect to those nodes which have more links. If the network is growing and new nodes tend to connect to existing ones with linear probability in the degree of the existing nodes then preferential attachment leads to a scale-free network.... |
https://en.wikipedia.org/wiki/De%20novo%20gene%20birth | De novo gene birth is the process by which new genes evolve from DNA sequences that were ancestrally non-genic. De novo genes represent a subset of novel genes, and may be protein-coding or instead act as RNA genes. The processes that govern de novo gene birth are not well understood, although several models exist that... |
