MATHEMATICAL MODELLING — AN EXAMPLE FROM AN INTER-SCHOOL MODELLING CHALLENGE

, 2015
The notion of mathematical modelling is not new; however, with the development and access to cheap, powerful calculator and computer technologies, students in schools are able to engage with sophisticated mathematical contexts that have relevance outside

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.

Insights from quantitative and mathematical modelling on the proposed WHO 2030 goal for schistosomiasis [PDF]

, 2019
Schistosomiasis remains one of the neglected tropical diseases (NTDs) impacting millions of people around the world. The World Health Organization (WHO) recently proposed a goal of elimination as a public health problem (EPHP) for schistosomiasis to be ...

Modeling Patterns of Population Exposure With a Multiscale Framework Utilizing LOTOS‐EUROS Chemical Transport Model, Mobility Surveys and Particulate Toxicity

GeoHealth
The present study proposes a high‐resolution, multi‐component framework to estimate human exposure to air pollution in tropical urban environments, addressing complex topography and limited historical mobility and exposure data. This framework is applied

Neurocognitive, School‐Based, and Quality of Life Outcomes for Youth With Sickle Cell Disease and Thalassemia: A Scoping Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

The effect of travel restrictions on the geographical spread of COVID-19 between large cities in China: a modelling study

BMC Medicine, 2020
Background To contain the spread of COVID-19, a cordon sanitaire was put in place in Wuhan prior to the Lunar New Year, on 23 January 2020. We assess the efficacy of the cordon sanitaire to delay the introduction and onset of local transmission of COVID ...
