https://en.wikipedia.org/wiki/Signaling%20compression | For data compression, signaling compression, or SigComp, is a compression method designed especially for compression of text-based communication data as SIP or RTSP. SigComp had originally been defined in RFC 3320 and was later updated with RFC 4896. A Negative Acknowledgement Mechanism for Signaling Compression is def... |

https://en.wikipedia.org/wiki/Golomb%E2%80%93Dickman%20constant | In mathematics, the Golomb–Dickman constant arises in the theory of random permutations and in number theory. Its value is
It is not known whether this constant is rational or irrational.
Definitions
Let an be the average — taken over all permutations of a set of size n — of the length of the longest cycle in eac... |
https://en.wikipedia.org/wiki/Zero-overhead%20looping | Zero-overhead looping is a feature of some processor instruction sets whose hardware can repeat the body of a loop automatically, rather than requiring software instructions which take up cycles (and therefore time) to do so. Zero-overhead loops are common in digital signal processors and some CISC instruction sets.

https://en.wikipedia.org/wiki/Step%20response | The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a ver... |
https://en.wikipedia.org/wiki/Hydrogen%20sulfide%20chemosynthesis | Hydrogen sulfide chemosynthesis is a form of chemosynthesis which uses hydrogen sulfide. It is common in hydrothermal vent microbial communities Due to the lack of light in these environments this is predominant over photosynthesis
Giant tube worms use bacteria in their trophosome to fix carbon dioxide (using hydrogen... |
https://en.wikipedia.org/wiki/Transistor%20array | Transistor arrays consist of two or more transistors on a common substrate. Unlike more highly integrated circuits, the transistors can be used individually like discrete transistors. That is, the transistors in the array are not connected to each other to implement a specific function. Transistor arrays can consist of... |
https://en.wikipedia.org/wiki/Software%20Guard%20Extensions | Intel Software Guard Extensions (SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). They allow user-level and operating system code to define protected private regions of memory, called enclaves. SGX is designed to be useful for ... |
