The Shannon capacity of a graph is a concept in information theory that relates to the maximum rate at which information can be transmitted over a noisy channel represented by the graph, while ensuring that the probability of error in the transmission approaches zero as the number of transmitted messages increases. Specifically, the Shannon capacity \( C(G) \) of a graph \( G \) is defined as the supremum of the rates at which information can be reliably transmitted over the channel represented by the graph.
The Pentagonal Number Theorem is a result in number theory associated with the generating function for partition numbers. Specifically, it relates to the representation of integers as sums of pentagonal numbers.
Genocidal intent refers to the intention behind acts that aim to destroy, in whole or in part, a national, ethnic, racial, or religious group. It is a key element in the legal definition of genocide, as established by international law, particularly the 1948 Convention on the Prevention and Punishment of the Crime of Genocide.
A moral imperative is a principle or rule that compels individuals to act in a way that is deemed ethically necessary or required. It represents a strong, often universal obligation to act in accordance with moral values or ethical standards, usually suggesting that there is a "right" course of action that should be followed in a given situation.
A Letter of Intent (LOI) is a document that outlines the preliminary understanding between two or more parties who intend to enter into a formal agreement or contract. It is commonly used in various business contexts, including mergers and acquisitions, partnerships, real estate transactions, and academic programs. The purpose of an LOI is to clarify the intentions of the parties involved and to outline the key aspects of the proposed agreement.
Moral agency refers to the capacity of an individual or entity to make moral decisions and judgments based on ethical principles. It involves the ability to act with understanding of right and wrong and the capability to be held accountable for one’s actions. A moral agent possesses the following key characteristics: 1. **Autonomy**: The ability to make choices freely and independently, without coercion.
Probe electrospray ionization (PESI) is a technique used in mass spectrometry for the ionization of samples, particularly in the analysis of biomolecules, drugs, and other complex mixtures. It is a variant of electrospray ionization (ESI), which is a widely used ionization method. In PESI, a probe is used to directly sample the analyte from a solid or liquid surface.
An isoscape is a spatial representation of the variability of isotopic compositions across a given landscape or environment. The term combines "iso," referring to isotopes, and "scape," which implies a landscape or geographical area. Isoscapes are often constructed using geostatistical methods and can illustrate how isotopic signatures, such as those from carbon, nitrogen, oxygen, or hydrogen, vary spatially. Isoscapes are useful in various scientific fields, including ecology, geology, and archaeology.
Transferred intent is a legal doctrine in tort law that allows for a defendant's intent to harm one person to be transferred to another person who is actually harmed. This principle operates under the assumption that if an individual intended to commit a wrongful act against one party but accidentally harmed a different party, the intent can be "transferred" to the actual victim.
Differential Optical Absorption Spectroscopy (DOAS) is a remote sensing technique used to measure the concentrations of trace gases in the atmosphere. The method is based on the analysis of the absorption spectrum of light as it passes through a volume of air containing the target gases. Here are key components and concepts associated with DOAS: 1. **Optical Absorption**: Different gases absorb light at specific wavelengths.
Electrical Resistivity Tomography (ERT) is a geophysical imaging technique used to investigate subsurface structures and properties by measuring the electrical resistivity of the ground. This method is based on the principle that different materials (such as water, minerals, and soil) have varying levels of electrical resistivity. ### Key Components and Principles of ERT: 1. **Electrode Configuration**: ERT involves the use of multiple electrodes (usually metal) that are inserted into the ground in a specific configuration.
Inverse dynamics is a computational method used in biomechanics and robotics to calculate the forces and moments acting on a system based on its motion. Specifically, it refers to the process of determining the internal and external forces (such as muscle forces, joint reactions, and ground reaction forces) that produce observed motion when the kinematics (positions, velocities, and accelerations of the system) are known.
Optimal estimation is a statistical method used to infer the values of unknown parameters or state variables based on observed data, minimizing estimation errors. This approach is commonly applied in various fields such as engineering, statistics, economics, and environmental science. The main goal is to produce the most accurate estimates possible by integrating various sources of information while considering uncertainties.
Californium (Cf) has several isotopes, of which the most notable are: 1. **Californium-252 (Cf-252)**: This isotope is one of the most prominent, with a half-life of about 2.645 years. It is a powerful neutron emitter and is used in various applications, including neutron radiography, chemotherapy, and as a neutron source in scientific research.
Actinium (Ac) has several isotopes, with the most notable being Actinium-227 and Actinium-228. Here are some details about its isotopes: 1. **Actinium-227 (Ac-227)**: - Half-life: About 21.77 years. - Decay mode: It decays to radium-223 via alpha decay.
Arsenic has several isotopes, with the most notable being: 1. **Arsenic-75 (As-75)**: This is the only stable isotope of arsenic and is the most abundant, making up about 100% of naturally occurring arsenic. 2. **Radioactive Isotopes**: Arsenic has several radioactive isotopes, which are not stable and decay over time.
Bromine has several isotopes, but the two most notable ones are: 1. **Bromine-79 (Br-79)**: This is the most stable and abundant isotope of bromine, making up about 50.5% of naturally occurring bromine. It has a half-life that is stable (not radioactive), and it consists of 35 protons and 44 neutrons.
Cobalt has several isotopes, but the most notable ones are: 1. **Cobalt-59 (^59Co)** - This is the only stable isotope of cobalt, making up nearly 100% of naturally occurring cobalt. It has 27 protons and 32 neutrons. 2. **Cobalt-60 (^60Co)** - This is a radioactive isotope with a half-life of about 5.27 years.
Europium (Eu) has a number of isotopes, but the most significant ones are Europium-151 and Europium-153, which are the only naturally occurring isotopes. 1. **Europium-151 (Eu-151)**: This isotope has an atomic mass of approximately 150.9198 u and has a natural abundance of about 47.8%. It is stable and does not undergo radioactive decay.

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.
