A **synchronizer** in the context of algorithms and computer science generally refers to mechanisms or techniques used to ensure that multiple parallel processes or threads of execution operate in a coordinated manner. The goal of synchronization is to prevent race conditions and ensure data consistency when multiple threads access shared resources. Here are some key concepts related to synchronizers: 1. **Mutexes (Mutual Exclusion)**: A mutex is a locking mechanism that ensures that only one thread can access a resource at a time.
Metastability in the brain refers to a dynamic state where neural systems exhibit a degree of stability while remaining poised between different configurations or states of activity. This concept is often used in the context of brain function, especially concerning how different brain regions interact and process information. Here are some key aspects of metastability in the brain: 1. **Dynamic Balance**: Metastable states involve a balance between stability and flexibility.
Neural decoding is a process in neuroscience and artificial intelligence that involves interpreting neural signals to infer information about the external world, brain activities, or cognitive states. It typically focuses on understanding how neural activity corresponds to specific stimuli, behaviors, or cognitive processes. Here are some key aspects of neural decoding: 1. **Measurement of Neural Activity**: Neural decoding often begins with the collection of raw data from neural activity.
Neurosecurity is an emerging field that focuses on the protection of neural data and the safeguarding of brain-computer interfaces (BCIs), neurotechnology, and cognitive functions from unauthorized access and malicious activities. As neuroscience and technology continue to advance, particularly in the development of BCIs, neurosecurity addresses various concerns related to privacy, ethics, and security in neurotechnological applications.
Ogi Ogas is a neuroscientist and author, known for his work on topics related to neuroscience, artificial intelligence, and behavior. He has co-authored several books, including "A Billion Wicked Thoughts," which explores the sexual preferences of men and women using data from online behavior. Ogas has been involved in research that examines how the brain processes information and how this knowledge can be applied to understand human behavior, including aspects related to sexual attraction and decision-making.
The spike-triggered average (STA) is a method used in computational neuroscience to characterize the relationship between neuronal spike train activity and sensory stimuli. It involves analyzing how specific inputs or stimuli relate to the output of a neuron, particularly the times at which the neuron fires action potentials (or spikes). Here's how it works, step by step: 1. **Data Collection:** A neuron's spiking activity is recorded alongside a sensory stimulus (such as a visual or auditory signal).
Merge sort is a classic, efficient, and stable sorting algorithm that follows the divide-and-conquer strategy. It was invented by John von Neumann in 1945. Here's a breakdown of how it works: ### Key Concepts: 1. **Divide:** - The input array is divided into two halves. This process continues recursively until each subarray has one or zero elements, at which point they can be considered sorted.
The "List of named minor planets: Y" refers to a catalog of minor planets (also known as asteroids) that have been given proper names and whose names begin with the letter "Y." Each entry typically includes the minor planet's designation (number) and its name, along with relevant details such as its discovery, orbit, or other notable information. Minor planets are celestial objects that orbit the Sun and are not classified as comets.
The list of named minor planets, specifically those beginning with the letter "Z," includes various asteroids that have been designated with specific names. However, the complete and up-to-date list of these objects can typically be found in databases maintained by astronomical organizations, such as the International Astronomical Union (IAU) or specialized websites like the JPL Small-Body Database.
The "List of named minor planets (numerical)" is a compilation of minor planets (also known as asteroids) that have been assigned specific numerical designations as well as names. These minor planets are primarily located in the asteroid belt between Mars and Jupiter, but they can also include objects from other regions of the solar system.
The "List of minor planets: 143001–144000" refers to a catalog of minor planets, also known as asteroids, that have been numbered in that specific range by the Minor Planet Center (MPC). Each minor planet is assigned a unique number upon its confirmation of discovery, along with a name or designation.
The List of minor planets 107001–108000 refers to a sequencing of asteroids and other minor planets that have been numbered by the International Astronomical Union (IAU). Each minor planet is given a unique number upon discovery, and this range would include various minor bodies in the solar system, primarily asteroids located in the asteroid belt between Mars and Jupiter, but it can also include trans-Neptunian objects and other minor celestial bodies.
The list of minor planets numbered between 117001 and 118000 consists of various small celestial bodies that orbit the Sun, typically categorized as asteroids. Each of these minor planets is assigned a unique number and often has a name. This list is maintained by the International Astronomical Union (IAU).
The "List of minor planets: 126001–127000" refers to a catalog of numbered minor planets (or asteroids) that have been discovered and observed. Each minor planet is assigned a unique number upon discovery, and these numbers help astronomers track and research these celestial objects. As of my last update, minor planets numbered from 126001 to 127000 include different celestial objects that can range in size, composition, and location within the solar system.
The list of minor planets numbered from 128001 to 129000 includes a variety of small celestial bodies orbiting the Sun. These minor planets are cataloged by their numerical designation, and they include asteroids and sometimes comets. Each entry typically includes the designation number, the name (if one has been assigned), and sometimes additional data like discovery date, orbit information, and size estimates.
The list of minor planets numbered between 13001 and 14000 includes various celestial bodies that have been identified and cataloged in the asteroid belt and beyond. Each minor planet typically has a unique number and often, but not always, a name associated with it.
The list of minor planets numbered between 14,001 and 15,000 includes a range of asteroids that have been assigned permanent numbers by the Minor Planet Center. Each of these minor planets is typically given a provisional designation before being assigned a number and, occasionally, a name.
The list of minor planets numbered between 157001 and 158000 consists of various small celestial bodies in our solar system that have been assigned a unique number by the Minor Planet Center. These minor planets can include asteroids, some of which are found in the asteroid belt between Mars and Jupiter, as well as other small objects in different orbits around the Sun.
The "List of minor planets: 155001–156000" refers to a specific range of numbered minor planets (also known as asteroids) in the Solar System that have been cataloged by the Minor Planet Center. These minor planets are given a number when they are discovered and confirmed as distinct objects.
The "List of minor planets: 256001–257000" refers to a catalog of minor planets (also known as asteroids) that have been assigned numerical designations ranging from 256001 to 257000. Minor planets are small celestial bodies within the Solar System that are not classified as comets. Each minor planet is typically given a unique identifier consisting of a number and a name.

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.
