https://en.wikipedia.org/wiki/ST2%20cardiac%20biomarker
The ST2 cardiac biomarker (also known as soluble interleukin 1 receptor-like 1) is a protein biomarker of cardiac stress encoded by the IL1RL1 gene. ST2 signals the presence and severity of adverse cardiac remodeling and tissue fibrosis, which occurs in response to myocardial infarction, acute coronary syndrome, or wor...
https://en.wikipedia.org/wiki/Stream%20restoration
Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development. Stream restoration approaches can be divided into two broad categ...

Network Systems Corporation (NSC) was an early manufacturer of high-performance computer networking products. Founded in 1974, NSC produced hardware products that connected IBM and Control Data Corporation (CDC) mainframe computers to peripherals at remote locations. NSC also developed and commercialized the HYPERcha...
https://en.wikipedia.org/wiki/Pole%20splitting
Pole splitting is a phenomenon exploited in some forms of frequency compensation used in an electronic amplifier. When a capacitor is introduced between the input and output sides of the amplifier with the intention of moving the pole lowest in frequency (usually an input pole) to lower frequencies, pole splitting caus...
https://en.wikipedia.org/wiki/Classical%20modal%20logic
In modal logic, a classical modal logic L is any modal logic containing (as axiom or theorem) the duality of the modal operators that is also closed under the rule Alternatively, one can give a dual definition of L by which L is classical if and only if it contains (as axiom or theorem) and is closed under the rule ...

In modal logic, a regular modal logic is a modal logic containing (as axiom or theorem) the duality of the modal operators: and closed under the rule Every normal modal logic is regular, and every regular modal logic is classical. References Chellas, Brian. Modal Logic: An Introduction. Cambridge University Press, ...

Green hosting or eco-friendly hosting is Internet hosting that involves strategies to reduce the environmental impact of their activities. These may include the increased use of renewable energy, planting trees, plants, and grass around and over data centers, and more day-to-day activities such as energy conservation a...
https://en.wikipedia.org/wiki/Hatley%E2%80%93Pirbhai%20modeling
Hatley–Pirbhai modeling is a system modeling technique based on the input–process–output model (IPO model), which extends the IPO model by adding user interface processing and maintenance and self-testing processing. The five components—inputs, outputs, user interface, maintenance, and processing—are added to a system...
https://en.wikipedia.org/wiki/Isolation%20amplifier
Isolation amplifiers are a form of differential amplifier that allow measurement of small signals in the presence of a high common mode voltage by providing electrical isolation and an electrical safety barrier. They protect data acquisition components from common mode voltages, which are potential differences between ...
