https://en.wikipedia.org/wiki/Hilbert%20spectrum | The Hilbert spectrum (sometimes referred to as the Hilbert amplitude spectrum), named after David Hilbert, is a statistical tool that can help in distinguishing among a mixture of moving signals. The spectrum itself is decomposed into its component sources using independent component analysis. The separation of the c... |
https://en.wikipedia.org/wiki/GP5%20chip | The GP5 is a co-processor accelerator built to accelerate discrete belief propagation on factor graphs and other large-scale tensor product operations for machine learning. It is related to, and anticipated by a number of years, the Google Tensor Processing Unit
It is designed to run as a co-processor with another co... |
https://en.wikipedia.org/wiki/Hot-carrier%20injection | Hot carrier injection (HCI) is a phenomenon in solid-state electronic devices where an electron or a “hole” gains sufficient kinetic energy to overcome a potential barrier necessary to break an interface state. The term "hot" refers to the effective temperature used to model carrier density, not to the overall tempera... |
https://en.wikipedia.org/wiki/Multiseat%20configuration | A multiseat, multi-station or multiterminal system is a single computer which supports multiple independent local users at the same time.
A "seat" consists of all hardware devices assigned to a specific workplace at which one user sits at and interacts with the computer. It consists of at least one graphics device (g... |
https://en.wikipedia.org/wiki/Molecular%20risk%20assessment | Molecular risk assessment is a procedure in which biomarkers (for example, biological molecules or changes in tumor cell DNA) are used to estimate a person's risk for developing cancer. Specific biomarkers may be linked to particular types of cancer.

https://en.wikipedia.org/wiki/Copeland%E2%80%93Erd%C5%91s%20constant | The Copeland–Erdős constant is the concatenation of "0." with the base 10 representations of the prime numbers in order. Its value, using the modern definition of prime, is approximately
0.235711131719232931374143… .
The constant is irrational; this can be proven with Dirichlet's theorem on arithmetic progressions or... |
https://en.wikipedia.org/wiki/Connectedness | In mathematics, connectedness is used to refer to various properties meaning, in some sense, "all one piece". When a mathematical object has such a property, we say it is connected; otherwise it is disconnected. When a disconnected object can be split naturally into connected pieces, each piece is usually called a comp... |
https://en.wikipedia.org/wiki/Pulsed-field%20gel%20electrophoresis | Pulsed-field gel electrophoresis (PFGE) is a technique used for the separation of large DNA molecules by applying to a gel matrix an electric field that periodically changes direction. Pulsed-field gel electrophoresis is a method used to separate large segments of DNA using an alternating and cross field. In a uniform ... |
https://en.wikipedia.org/wiki/Circumscriptional%20name | In biological classification, circumscriptional names are taxon names that are not ruled by ICZN and are defined by the particular set of members included. Circumscriptional names are used mainly for taxa above family-group level (e. g. order or class), but can be also used for taxa of any ranks, as well as for rank-le... |
