How rare are extreme-spin primordial black holes? We show how, from an underlying distribution of PBH spin, extreme-value statistics can be used to quantify the rarity spinning PBHs with Kerr parameter close 1. Using Peaks-Over-Threshold method, we how probability that a forms spin exceeding sufficiently high threshold calculated using Generalised Pareto Distribution. This allows us estimate av...
Background and Objectives: Given the importance of the early detection of any outbreak or change in the trend of meningitis, this study was conducted to estimate the fixed and dynamic alarm threshold levels of meningitis and its outbreak in Iran. Materials and Methods: In this study, the data of all patients from 20¬ March 2016 to 20 March 2019 were extracted from the National Meningitis Di...
The deterministic limit of a Hopfield-type mutation-selection model in the sequence space approach is investigated. Genotypes are identified with two-letter sequences. Mutation is modelled as a Markov process, fitness functions are of Hopfield type, where the fitness of a sequence is determined by the Hamming distances to a number of predefined patterns. Using a maximum principle for the popula...
In this work, a generalized study of the conditions for appearance limit cycle oscillations induced by any kind sampler with multilevel fixed thresholds is presented. These kinds samplers, which will be referred to as Fixed Threshold Samplers (FTS), are characterized series parameters, which, when selected properly, allow obtaining some most used forms quantization in Event-Based Control (EBC)....
