Price of stability
The Price of Stability (PoS) is a concept in game theory and algorithmic social choice that measures the efficiency of equilibria in games, particularly in the context of strategic interactions among multiple agents or players. Specifically, it quantifies how much the performance of the best Nash equilibrium (a stable state where no player has anything to gain by changing only their own strategy) deviates from the optimal outcome that could be achieved with cooperation.
Adverse inference
Adverse inference is a legal principle that allows a court to infer that evidence which is not presented or is withheld by a party would have been unfavorable to that party's case. This principle often applies in situations where a party fails to produce evidence that is relevant and within their control, raising the presumption that the evidence would have been detrimental to their position.
Isotopes of caesium
Caesium (Cs) has several isotopes, with the most stable and commonly known ones being: 1. **Cs-133**: This is the most stable isotope of caesium and is used as the standard for the definition of the second in the International System of Units (SI). Cs-133 has a half-life of stable, meaning it does not undergo radioactive decay.
The correlation between relatives under Mendelian inheritance can be understood through the concept of genetic relatedness, which quantifies the probability that two individuals share alleles inherited from a common ancestor. Mendelian inheritance describes how genes are transmitted from parents to offspring, primarily through dominant and recessive alleles. The degree of genetic relatedness can be expressed as the coefficient of relationship (r), which reflects the probability that two individuals share a certain allele due to their kinship.
The Computerized Approach to Residential Land Analysis refers to the utilization of computer technology and software to evaluate, analyze, and manage residential land for various purposes, such as urban planning, real estate development, property appraisal, and environmental assessment. This approach often involves the integration of Geographic Information Systems (GIS), remote sensing, and data analytics to gather, analyze, and visualize spatial data related to land use, zoning, demographics, infrastructure, and environmental features.
