KCNH3 is a gene that encodes a protein belonging to the family of voltage-gated potassium channels. These channels are critical for the repolarization phase of action potentials in neurons and other excitable cells, playing a vital role in maintaining the electrical activity of cells, regulating heart rhythms, and contributing to various physiological processes. The KCNH3 protein is particularly associated with the regulation of neuronal excitability and has been implicated in certain neurological functions.
Just tuning is a musical tuning system that is based on a series of simple frequency ratios for the intervals between notes. This approach to tuning emphasizes pure intervals that align with the harmonic series, which is the natural overtone series produced by vibrating strings or air columns. In just tuning, intervals are derived from whole-number ratios, which results in consonant and harmonically pleasing sounds.
Key pre-distribution is a method used in cryptography, particularly in the context of wireless sensor networks and other distributed systems, to establish secure communication among nodes without relying heavily on a centralized key management system. In key pre-distribution, a set of cryptographic keys is distributed to network nodes before they are deployed. This process typically involves the following steps: 1. **Key Generation**: A large pool of keys is generated beforehand.
The Quantum Counting algorithm is a quantum computing algorithm that combines elements of Grover's Search algorithm with quantum phase estimation to count the number of marked items in an unstructured search space efficiently. The main focus of the algorithm is to count how many solutions (or marked items) exist in a given set, where the solutions can be identified using a specific oracle function.

Lavizan-Shian is a location in Iran, specifically as part of the broader Tehran metropolitan area. It is known for its residential neighborhoods and has been the site of various developments over the years. The area has gained attention partly due to its proximity to important urban and suburban infrastructure, including educational institutions and parks.
A light pillar is an atmospheric optical phenomenon that appears as a vertical beam of light extending above or below a light source, usually in cold weather conditions. It occurs due to the refraction of light through ice crystals suspended in the atmosphere, such as those found in cirrus or other high-altitude clouds. Light pillars can be observed near the horizon from streetlights, the Sun, or other bright light sources.
Lipid-gated ion channels are a type of ion channel that opens or closes in response to changes in the lipid composition of the surrounding membrane rather than being directly activated by voltage changes (as is the case with voltage-gated ion channels) or ligand binding (as seen in ligand-gated ion channels).
Anti-nuclear power groups are organizations or movements that oppose the use of nuclear power for electricity generation due to concerns about safety, waste management, environmental impacts, and the potential for nuclear accidents or proliferation. Here's a list of some notable anti-nuclear power groups: 1. **Greenpeace** - An international environmental organization that campaigns against nuclear power due to concerns over safety and environmental impacts.

The Jupiter trojans are a group of asteroids that share an orbit with Jupiter, located at stable Lagrange points (L4 and L5) ahead of and behind the planet in its orbit around the Sun. The Greek camp refers to one of the two main groups of Jupiter trojans, named after figures from Greek mythology associated with the Trojan War.
The list of minor planets numbered 150001 to 151000 includes various small celestial bodies that orbit the Sun. These minor planets, often referred to as asteroids, have been cataloged by the Minor Planet Center and are officially designated with their designated numbers.
The list of minor planets numbered 207001 to 208000 includes various small celestial bodies (typically asteroids) found in the solar system. These objects are cataloged by the Minor Planet Center and are designated with unique numerical identifiers.
The list of minor planets named after rivers includes celestial objects designated as asteroids that have been named to honor various rivers around the world. While I can’t provide an exhaustive or current list due to my last update being in October 2023, here are a few notable examples of minor planets named after rivers: 1. **1370 Acheron** - Named after the Acheron River, which is associated with Greek mythology and often referred to as the river of woe.
The list of minor planets numbered from 233001 to 234000 includes a variety of objects in the asteroid belt and beyond, which have been assigned a number by the Minor Planet Center after their discovery. Each minor planet is typically named following certain conventions, which may include names of individuals, places, or mythological references. However, specific information about each individual minor planet, like their physical characteristics, orbital parameters, and discovery details, can be found through astronomical databases or observatory records.
The list of minor planets numbered 238001 to 239000 includes a collection of small celestial bodies, primarily asteroids, that have been cataloged by the Minor Planet Center. Each of these minor planets has been assigned a unique number, typically consisting of numerical identifiers, along with other details such as their discovery date and sometimes their names.
Group isomorphism is a concept in the field of abstract algebra, particularly in the study of group theory. Two groups \( G \) and \( H \) are said to be isomorphic if there exists a bijective function (one-to-one and onto mapping) \( f: G \to H \) that preserves the group operation.
The list of minor planets numbered from 264001 to 265000 includes a range of small celestial bodies, often referred to as asteroids, that are orbiting the Sun.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
