Computing the eigenvalues of realistic Daphnia models by pseudospectral methods
(2015-12-31)This work deals with physiologically structured populations of the Daphnia type. Their biological modeling poses several computational challenges. In such models, indeed, the evolution of a size structured consumer described ... -
A concerted systems biology analysis of phenol metabolism in Rhodococcus opacus PD630
(2019-06)Rhodococcus opacus PD630 metabolizes aromatic substrates and naturally produces branched-chain lipids, which are advantageous traits for lignin valorization. To provide insights into its lignocellulose hydrolysate utilization, ... -
Condition-specific mortality risk can explain differences in COVID-19 case fatality ratios around the globe
Aguiar, M.; Stollenwerk, N. (2020-09)
Objectives With COVID-19 infections resulting in death according to a hierarchy of risks, with age and pre-existing health conditions enhancing disease severity, the objective of this study is to estimate the condition-specific ... -
Conductance-Based Refractory Density Approach for a Population of Bursting Neurons
Chizhov, A.; Campillo, F.; Desroches, M.; Guillamon A; Rodrigues, S. (2019)
The conductance-based refractory density (CBRD) approach is a parsimonious mathematical-computational framework for modeling interact- ing populations of regular spiking neurons, which, however, has not been yet extended ... -
Constant pressure hybrid Monte Carlo simulations in GROMACS
Fernández-Pendás, M.; Escribano, B.; Radivojevic, T.; Akhmatskaya, E. (2014-12-31)
Adaptation and implementation of the Generalized Shadow Hybrid Monte Carlo (GSHMC) method for molecular simulation at constant pressure in the NPT ensemble are discussed. The resulting method, termed NPT-GSHMC, combines ... -
