(Scientific Reports, 2019-11-07)
Invasive species are recognized as a significant threat to biodiversity. The mathematical modeling of their spatio-temporal dynamics can provide significant help to environmental managers in devising suitable control ...
• #### Clinical correlates of mathematical modeling of cortical spreading depression: Single‐cases study ﻿

(Brain and Behavior, 2019-07-28)
Introduction: Considerable connections between migraine with aura and cortical spreading depression (CSD), a depolarization wave originating in the visual cortex and traveling toward the frontal lobe, lead to the hypothesis ...
• #### A roadmap to integrate astrocytes into Systems Neuroscience ﻿

(Glia, 2019-05-06)
Systems Neuroscience is still mainly a neuronal field, despite the plethora of evidence supporting the fact that astrocytes modulate local neural circuits, networks, and complex behaviors. In this article, we sought to ...
• #### Metastable resting state brain dynamics ﻿

(Frontiers in Computational Neuroscience, 2019-09-06)
Metastability refers to the fact that the state of a dynamical system spends a large amount of time in a restricted region of its available phase space before a transition takes place, bringing the system into another state ...
• #### Modified Hamiltonian Monte Carlo for Bayesian Inference ﻿

(Statistics and Computing, 2019-07-22)
The Hamiltonian Monte Carlo (HMC) method has been recognized as a powerful sampling tool in computational statistics. We show that performance of HMC can be significantly improved by incorporating importance sampling and ...
• #### Opportunities at the Intersection of Synthetic Biology, Machine Learning, and Automation ﻿

(ACS Synthetic Biology, 2019-07)
Our inability to predict the behavior of biological systems severely hampers progress in bioengineering and biomedical applications. We cannot predict the effect of genotype changes on phenotype, nor extrapolate the ...
• #### A concerted systems biology analysis of phenol metabolism in Rhodococcus opacus PD630 ﻿

(Metabolic Engineering, 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, ...
• #### Conductance-Based Refractory Density Approach for a Population of Bursting Neurons ﻿

(Bulletin of Mathematical Biology, 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 ...
• #### Exploring Li-ion conductivity in cubic, tetragonal and mixed-phase Al-substituted Li7La3Zr2O12 using atomistic simulations and effective medium theory ﻿

(Acta Materialia, 2019-08-15)
Garnet Li7La3Zr2O12 (LLZO) is a promising solid electrolyte candidate for solid-state Li-ion batteries, but at room temperature it crystallizes in a poorly Li-ion conductive tetragonal phase. To this end, partial substitution ...
• #### Brain energetics plays a key role in the coordination of electrophysiology, metabolism and hemodynamics: evidence from an integrated computational model ﻿

(Journal of theoretical biology, 2019-06-05)
The energetic needs of brain cells at rest and during elevated neuronal activation has been the topic of many investigations where mathematical models have played a significant role providing a context for the interpretation ...
• #### Patient-specific modelling of cortical spreading depression applied to migraine studies ﻿

(2019-06-17)
Migraine is a common neurological disorder and one-third of migraine patients suffer from migraine aura, a perceptual disturbance preceding the typically unilateral headache. Cortical spreading depression (CSD), a ...
• #### Machine learning framework for assessment of microbial factory performance ﻿

(Plos ONE, 2019-01-01)
