It provides a valuable resource for researchers studying the brain and neurological diseases.

BCM theory, or Bardeen-Cooper-Schrieffer theory, is a theoretical framework that describes superconductivity in many materials. Developed in 1957 by John Bardeen, Leon Cooper, and Robert Schrieffer, this theory explains how certain materials can conduct electricity without resistance when cooled to very low temperatures. Key concepts of BCM theory include: 1. **Cooper Pairs**: At low temperatures, electrons in a superconductor can form pairs known as Cooper pairs.

A biological neuron model is a representation of the structure and function of neurons, which are the fundamental units of the brain and nervous system. Neurons transmit information throughout the body via electrical and chemical signals. While there are various ways to model neurons, the most common approaches include simplified models that emphasize their essential characteristics and more detailed biophysical models that capture the complexity of neuronal behavior.

Bible code refers to a purported set of secret messages encoded within the Hebrew text of the Bible, particularly the Torah (the first five books of the Old Testament). Proponents of Bible code theories claim that by using various methods of letter skipping or equidistant letter sequences, one can find hidden predictions or prophecies about future events, names of people, and other significant occurrences.

It is possible that he may be a private individual or a professional in a specific field that has not gained significant public attention. If you have more context or specific details about who Gašper Tkačik is or the relevant domain (such as science, art, sports, etc.

Spin polarization refers to the distribution of electron spins in a material or a system, which can result in a net magnetic moment due to an imbalance in the populations of spin-up and spin-down states. In quantum mechanics, electrons possess an intrinsic angular momentum known as "spin," which can be thought of as a kind of internal magnetic moment. When a material exhibits spin polarization, it means that there is a preference for one of the spin states over the other.

A spin valve is a type of device that exploits the phenomenon of spin-dependent electrical resistance, which is related to the spin of electrons. It consists generally of two ferromagnetic layers separated by a non-magnetic metal or semiconductor layer. The key principle behind a spin valve is that the electrical resistance of the device changes depending on the relative magnetization orientations of the two ferromagnetic layers.

Stuart Parkin is a notable physicist and engineer, best known for his contributions to the field of nanotechnology and information storage. He has made significant advancements in magnetic storage technologies, including the development of the concept of spin electronics (or spintronics), which exploits the intrinsic spin of electrons in addition to their charge for storage and information processing.

In physics, a "trion" refers to a quasiparticle that consists of three charge carriers, typically two electrons and a "hole," which is a missing electron in a semiconductor. Trions can behave like particles with fractional charges and are often studied in the context of two-dimensional materials, particularly in systems like transition metal dichalcogenides (TMDs).

The term "Biosphere model" could refer to various concepts across different disciplines, but it is commonly associated with ecological modeling and systems that represent the interactions within the biosphere, which includes all living organisms and their environments on Earth. Here are some general aspects of what a Biosphere model might involve: 1. **Ecological Modeling**: Biosphere models are often used to simulate the interactions between biological organisms and their environment.

The Climate Forecast Applications Network (CFAN) is an organization that focuses on the application of climate forecasts to support decision-making in various sectors, such as agriculture, water management, disaster response, and public health. CFAN aims to bridge the gap between climate science and practical applications by providing tools and resources that help users understand and utilize climate information effectively.

Nukemap is an interactive online tool created by historian Alex Wellerstein that simulates the effects of nuclear detonations. Users can select different types of nuclear weapons, choose a location on a map, and then see the potential impact of a nuclear explosion in terms of blast radius, thermal radiation, and fallout patterns. The tool allows users to explore various scenarios, such as the effects of different yields of nuclear weapons and the geographic consequences of detonating them in populated areas.

The Earth System Modeling Framework (ESMF) is a software architecture and computational framework designed to facilitate the development, coupling, and execution of Earth system models. This framework is particularly important for researchers and scientists who work in the domains of climate modeling, weather forecasting, and environmental science.

EdGCM, or the Educational Global Climate Model, is a user-friendly version of a climate modeling tool designed for educational purposes. It allows students and educators to explore climate change and its effects through hands-on experimentation with climate simulations. EdGCM enables users to run experiments that model the Earth's climate system, including factors like greenhouse gas concentrations, solar radiation, and other climate-related variables.

The Exner function, often denoted as \( \psi \), is a scalar function used in the field of fluid mechanics, especially in the study of rivers, lakes, and other open channel flows. It is particularly important in understanding sediment transport and the dynamics of riverbed profiles. In the context of sediment transport, the Exner function describes the change in elevation of the sediment bed over time as a function of sediment supply, transport capacity, and the flow conditions.
