Is Covid-19 severity associated with ACE2 degradation?
Ugo Bastolla, Patrick Chambers, David Abia +2
Covid-19 is particularly mild with children, and its severity escalates with age. Several theories have been proposed to explain these facts. In particular, it was proposed that th…
Mathematical model of SARS-Cov-2 propagation versus ACE2 fits COVID-19 lethality across age and sex and predicts that of SARS, supporting possible therapy
Ugo Bastolla
The fatality rate of Covid-19 escalates with age and is larger in men than women. I show that these variations correlate strongly with the level of the viral receptor protein ACE2…
The maximum penalty criterion for ridge regression: application to the calibration of the force constant in elastic network models
Ugo Bastolla, Yves Dehouck
Multivariate regression is a widespread computational technique that may give meaningless results if the explanatory variables are too numerous or highly collinear. Tikhonov regula…
Does mutualism hinder biodiversity?
Alberto Pascual-García, Antonio Ferrera, Ugo Bastolla
A recent paper by James et al. finds that mutualistic interactions decrease the biodiversity of model ecosystems. However, this result can be reverted if we consider ecological tra…
Biodiversity in model ecosystems, II: Species assembly and food web structure
Ugo Bastolla, Michael Lässig, Susanna C. Manrubia +1
This is the second of two papers dedicated to the relationship between population models of competition and biodiversity. Here we consider species assembly models where the populat…
Biodiversity in model ecosystems, I: Coexistence conditions for competing species
Ugo Bastolla, Michael Lässig, Susanna C. Manrubia +1
This is the first of two papers where we discuss the limits imposed by competition to the biodiversity of species communities. In this first paper we study the coexistence of compe…
