Background Workplace transmission is a significant contributor to severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2) outbreaks. Previous studies have found that …

We describe the basic properties and consequences of introducing active stresses, with
principal direction along the local director, in cholesteric liquid crystals. The helical ground state …

Background The emergence of SARS-CoV-2 triggered a chain of public health responses
that radically changed our way of living and working. Non-healthcare sectors, such as the …

We consider two minimal models of activefluid droplets that exhibit complex dynamics including
steady motion, deformation, rotation and oscillating motion. First we consider a droplet …

One mechanism for airway closure in the lung is the surface-tension-driven instability of the
mucus layer which lines the airway wall. We study the instability of an axisymmetric layer of …

Repeat asymptomatic testing in order to identify and quarantine infectious individuals has
become a widely-used intervention to control SARS-CoV-2 transmission. In some workplaces, …

This paper introduces a linear operator for the purposes of quantifying the spectral properties
of transport within resistive trees, such as airflow in lung airway networks. The operator, …

Objective We aimed to use mathematical models of SARS-COV-2 to assess the potential
efficacy of non-pharmaceutical interventions on transmission in the parcel delivery and logistics …

To assess how the presence of surfactant in lung airways alters the flow of mucus that leads
to plug formation and airway closure, we investigate the effect of insoluble surfactant on the …

We have developed a computational model of gas mixing and ventilation in the human lung
represented as a bifurcating network. We have simulated multiple-breath washout (MBW), a …
