In computer science, particularly in the context of operating systems and concurrent programming, **starvation** refers to a situation where a process or thread is perpetually denied the resources it needs to proceed with its work, primarily due to the scheduling policies of the system. This often occurs when a process is waiting indefinitely for resources that are being monopolized by others.
Circuit quantum electrodynamics (cQED) is a field of research that explores the interaction between light (typically microwave photons) and artificial atoms, such as superconducting qubits, within a controlled environment. It is a hybrid approach that combines elements of quantum optics and condensed matter physics, enabling the study of quantum phenomena in a circuit-based framework.
Entanglement-assisted classical capacity refers to the maximum rate at which classical information can be transmitted over a quantum channel when the sender and receiver share entanglement. This concept is an important aspect of quantum information theory, which explores the transmission and processing of information using quantum systems. In classical information theory, channels can be characterized by their capacity to transmit bits of information.
The Leggett–Garg inequality is a concept in quantum mechanics that addresses the nature of macroscopic realities and the behavior of quantum systems. It was proposed by Anthony Leggett and Anupam Garg in the 1980s as a criterion for distinguishing between classical and quantum behavior in a system that evolves over time. The inequality is framed in the context of a series of measurements performed on a single quantum system at different times.
The No-Deleting Theorem is a concept from computer science, particularly in the context of programming languages and type systems. Specifically, it is most commonly associated with the field of functional programming and the study of certain types of data structures and algorithms.
Knowledge-based engineering (KBE) is an advanced engineering discipline that leverages knowledge-based systems and artificial intelligence techniques to enhance engineering processes, design, and decision-making. KBE integrates information, rules, and expert knowledge into software systems to support a variety of engineering tasks. Here's a more detailed breakdown: 1. **Definition and Purpose**: KBE aims to capture and reuse engineering knowledge, enabling engineers to automate repetitive tasks, make informed decisions, and enhance productivity.
Gestational age is a term used to describe the age of a pregnancy, typically measured in weeks from the first day of a woman's last menstrual period (LMP) to the current date or the date of delivery. It helps healthcare providers assess fetal development and determine expected due dates. Gestational age is usually divided into three trimesters: 1. **First Trimester:** Weeks 1 to 12 2. **Second Trimester:** Weeks 13 to 26 3.
MODELLER is a software tool used for homology or comparative modeling of protein structures. It allows researchers to predict the three-dimensional structures of proteins based on their amino acid sequences and known structures of related proteins (templates) from databases like the Protein Data Bank (PDB). Key features and functionalities of MODELLER include: 1. **Homology Modeling**: MODELLER uses known protein structures to generate models of similar proteins whose structures are not yet known.
Neurotechnology refers to an interdisciplinary field that combines neuroscience, engineering, and technology to develop devices and systems designed to interface with the nervous system. This can involve a range of applications, including the study and manipulation of neural activity, the enhancement of cognitive functions, and the treatment of neurological disorders.
Oja's rule is an unsupervised learning algorithm used in the field of neural networks and machine learning, particularly in the context of learning vector representations. It is a type of Hebbian learning rule, which is based on the principle that neurons that fire together, wire together. Oja's rule is specifically designed to allow a neural network to learn the principal components of the input data, effectively performing a form of principal component analysis (PCA).
Quantum game theory is an extension of classical game theory that incorporates principles of quantum mechanics into the modeling and analysis of strategic interactions among rational decision-makers. In classical game theory, players choose strategies to maximize their payoffs, often in a competitive context. When quantum mechanics is introduced, it introduces new dimensions of behavior and strategy due to phenomena such as superposition, entanglement, and measurement.
Quantum metrology is a field of science that utilizes principles from quantum mechanics to improve the precision and accuracy of measurements. It leverages quantum phenomena, such as superposition and entanglement, to enhance measurement sensitivity beyond what is possible with classical techniques. The core idea of quantum metrology is to use quantum states of light or matter to probe physical systems with greater precision.
In quantum mechanics, a "weak value" is a concept that arises in the context of weak measurements, which are a type of measurement that allows observers to extract information about a quantum system with minimal disturbance to the system itself. Weak values are defined in the context of a quantum measurement scenario involving a pre-selected and post-selected ensemble of quantum states.
The term "reduction strategy" can apply to various fields, including business, mathematics, computer science, and environmental science, among others. Here's a brief overview of what reduction strategies might mean in a few different contexts: 1. **Business/Financial Context**: - A reduction strategy could refer to actions taken by an organization to decrease costs, improve efficiency, or eliminate waste. This might include downsizing, streamlining operations, or adopting lean management practices to enhance productivity.
A swap spread is a financial term that refers to the difference between the fixed rate of a swap contract and the yield on a government bond of a similar maturity. It is commonly used in interest rate swaps, where one party exchanges a fixed interest payment for a floating interest payment, typically linked to an index like LIBOR or SOFR (Secured Overnight Financing Rate).

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.
