Disentangling the Information in Species Interaction Networks

Entropy, 2021
Shannon’s entropy measure is a popular means for quantifying ecological diversity. We explore how one can use information-theoretic measures (that are often called indices in ecology) on joint ensembles to study the diversity of species interaction ...

Forecasting SARS-CoV-2 epidemic dynamic in Poland with the pDyn agent-based model

Epidemics
We employ pDyn (derived from “pandemics dynamics”), an agent-based epidemiological model, to forecast the fourth wave of the SARS-CoV-2 epidemic, primarily driven by the Delta variant, in Polish society.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Video-based Word Problems or Modelling Projects—Classifying ICT-based Modelling Tasks [PDF]

, 2021
Mathematical modelling tasks increasingly feature the use of digital tools and media. In this chapter, we discuss the wide variety of these. Until now, classifications for modelling tasks did not consider the use of tools and media.
