Species traits shape the relationship between local and regional species abundance distributions
Ecosphere, 2019 The species abundance distribution (SAD) depicts the relative abundance of species within a community, which is a key concept in ecology. Here, we test whether SADs are more likely to either follow a lognormal‐like or follow a logseries‐like distribution

Time Integrals Under the Black–Scholes–Merton and Margrabe Economies
Journal of Futures Markets, EarlyView.ABSTRACT The problem of integrating the Black, Scholes, and Merton (BSM) formula with respect to the time variable is paramount for an economist. Inspired by the real options literature, Shackleton and Wojakowski offer analytic formulae for valuing finite maturity (profit) caps and floors that are contingent on continuous flows following a lognormal ...

Finding Most Reliable Path With Extended Shifted Lognormal Distribution
IEEE Access, 2018 Travel time uncertainty may cause late arrival and impose a high penalty on travelers. There is a growing interest in modeling travel time uncertainty to optimize the reliability of travel time at the path and network level. Real data analysis finds that

Density PDFs of diffuse gas in the Milky Way
, 2011 The probability distribution functions (PDFs) of the average densities of the diffuse ionized gas (DIG) and the diffuse atomic gas are close to lognormal, especially when lines of sight at |b|5 degree are considered separately. Our results provide strong
