Selection Rules Imposed by Charge Conjugation and Charge Symmetry
It is found that the invariance with respect to charge conjugation and charge symmetry combined leads to selection rules, additional to those following from covariance and gauge invariance arguments. Besides rigorous selection rules which hold for certain processes involving neutral particles (mesons and photons} only, there exist weak selection rules according to which certain boson-boson tran...
متن کاملStopping rule reversal for finite Markov chains
Consider a finite irreducible Markov chain with transition matrix M = (pij). Fixing a target distribution τ , we study a family of optimal stopping rules from the singleton distributions to τ . We show that this family of rules is dual to a family of (not necessarily optimal) rules on the reverse chain from the singleton distributions to a related distribution α̂ called the τ -contrast distribut...
متن کاملNEW CRITERIA FOR RULE SELECTION IN FUZZY LEARNING CLASSIFIER SYSTEMS
Designing an effective criterion for selecting the best rule is a major problem in theprocess of implementing Fuzzy Learning Classifier (FLC) systems. Conventionally confidenceand support or combined measures of these are used as criteria for fuzzy rule evaluation. In thispaper new entities namely precision and recall from the field of Information Retrieval (IR)systems is adapted as alternative...
متن کاملFluoroquinolone resistance and plasmid addiction systems: self-imposed selection pressure?
Multi-antibiotic-resistant Gram-negative pathogens are becoming more prevalent and an association exists between chromosomally conferred fluoroquinolone resistance and the presence of plasmid-borne resistances, such as extended spectrum beta-lactamases. This link is not wholly explained by strain spread or the presence of fluoroquinolone-modifying enzymes. Plasmid-encoded toxin-antitoxin addict...
متن کاملImposed cost induced by traffic injuries on society in 2021
Background and Aim: Due to the importance of the cost of traffic injuries, in addition to mental and social suffering, as well as the increasing trend of accident statistics and the lack of information about the cost estimation based on a willingness to pay model, this research was conducted on the findings of traffic injuries in 2021. Materials and Methods: The research was done by descr...
