Exploring the high dimensional parameter space using numerical simulations has been a frequently used technique in the last years in many areas of computational neuroscience. This makes the development of tools and strategies to efficiently find these regions of high importance to advance brain research. Neuroscience models commonly have a high number of degrees of freedom and only specific regions within the parameter space are able to produce dynamics of interest. To minimize the risk of transmission inside the classroom setup considered, it is vital to control these factors by adhering to mitigation efforts such as increased testing and symptoms checking, limiting the maximum number of students, and redefining breaks and class rotations. Results also showed that factors including maximum number of students and number of initially infected individuals, significantly affect the likelihood of infection apart from the seating arrangement itself. Furthermore, in three of the four seating arrangements, allowing in-class mobility and class rotations can pose significant increases in CPI averaging from 40 to 70%. Also, varying transmission rates between 5 and 20% does not pose any significant effect on CPI. Results show that the highest value of cumulative proportion of infected individuals inside the classroom (CPI) is achieved when the total allowable seating capacity in the classroom is increased from 25 to 50%. In this study, we implemented an agent-based model in Netlogo that followed common classroom layouts to assess the effects of human interactions to virus transmission. ![]() This forced millions of learners to adapt with new modes of instruction that may not be optimal for their learning. Onsite classes in the Philippines have been prohibited since March 2020 due to the SARS-CoV-2 which causes the COVID-19. Furthermore, in accordance with experimental evidence our model showed that shorter oxic/anoxic periods exhibit a faster increase of total Fe ³⁺ reduction rate than longer periods. Efficient iron-nanoparticle reduction is confined to pH around 6, being twice as high than at pH 7, whereas at pH 5 negligible reduction takes place. We predicted that the beneficial effect of a high number of iron-nanoparticles on the total Fe ³⁺ reduction rate of the system is not only due to the faster reduction of these iron-nanoparticles, but also to the nanoparticles’ additional capacity to bind Fe ²⁺ on their surfaces. We compared (i) combinations of different Fe ³⁺ -reducing/Fe ²⁺ -oxidizing modes of action of the bacteria and (ii) system behaviour for different pH values. By including the key processes of reduction/oxidation, movement, adhesion, Fe ²⁺ -equilibration and nanoparticle formation, we derive a core model which enables hypothesis testing and prediction for different environmental conditions including temporal cycles of oxic and anoxic conditions. and the microaerophilic ferrous iron (Fe ²⁺ )-oxidizing bacteria Sideroxydans spp. ![]() In this paper, we present the first computational agent-based model of microbial iron cycling, between the anaerobic ferric iron (Fe ³⁺ )-reducing bacteria Shewanella spp. Such bacteria often co-occur at oxic-anoxic gradients in aquatic and terrestrial habitats. Iron-reducing and iron-oxidizing bacteria are of interest in a variety of environmental and industrial applications.
