Back to the future: a simplified and intuitive derivation of the Lotka-Euler equation
Carlos Hernandez-Suarez
The Lotka-Euler equation is a mathematical expression used to study population dynamics and growth, particularly in the context of demography and ecology. The growth rate is th…
What is expected for China's SARS-CoV-2 epidemic?
Carlos Hernandez-Suarez, Efren Murillo-Zamora
Recently, China announced that its "zero-covid" policy would end, which will bring serious challenges to the country's health system. In here we provide simple calculations that al…
The fallacy of herd immunity
Carlos Hernandez-Suarez
Here we show that herd immunity is not a measure we can implement, trust, control or depend on, and that waiting for herd immunity to play a role is tantamount to hope for the best…
A simple and intuitive method to calculate in complex epidemic models
Carlos Hernandez-Suarez, Osval Montesinos Lopez
Epidemic models are a valuable tool in the decision making process. Once a mathematical model for an epidemics has been established, the very next step is calculating a mathematica…
Revised calculation of the coefficient of parentage in plant breeding
Carlos Hernandez-Suarez, Osval Montesinos Lopez
The Coefficient of Parentage (COP) between two individuals is the expected inbreeding of their offspring. Originally exploited by animal breeders, is now a routine calculation amon…
Collective targeted migrations: a balancing act involving aggregation, group size and environmental clues: a simulation study
Carlos Hernandez-Suarez
What is behind the \emph{wisdom of the crowds} described by Simons (2004)? It has been showed that insects may use gravitational fields to travel (Dreyer et al 2018) and we may ask…
The Poisson algorithm: a simple method to simulate stochastic epidemic models with generally distributed residence times
Carlos Hernandez-Suarez, Osval Montsinos Lopez, Ramon Solano-Barajas
Epidemic models are used to analyze the progression or outcome of an epidemic under different control policies like vaccinations, quarantines, lockdowns, use of face-masks, pharmac…
Mean and variance of first passage time in Markov chains with unknown parameters
Carlos Hernandez-Suarez
There are known expressions to calculate the moments of the first passage time in Markov chains. Nevertheless, it is commonly forgotten that in most applications the parameters of…
