The 1978 English boarding school influenza outbreak: where the classic SEIR model fails Open
Previous work has failed to fit classic SEIR epidemic models satisfactorily to the prevalence data of the famous English boarding school 1978 influenza A/H1N1 outbreak during the children’s pandemic. It is still an open question whether a …

Quantifying indirect and direct vaccination effects arising in the SIR model Open
Vaccination campaigns have both direct and indirect effects that act to control an infectious disease as it spreads through a population. Indirect effects arise when vaccinated individuals block disease transmission in any infection chain …

Assessing the impact of Australia’s mass vaccination campaigns over the Delta and Omicron outbreaks Open
Background The Australian Government implemented a national vaccination campaign against COVID-19 beginning February 22, 2021. The roll-out was criticised for being delayed relative to many high-income countries, but high levels of vaccina…

Modelling the unexpected dynamics of COVID-19 in Manaus, Brazil Open
In late March 2020, SARS-CoV-2 arrived in Manaus, Brazil, and rapidly developed into a large-scale epidemic that collapsed the local health system and resulted in extreme death rates. Several key studies reported that ∼76% of residents of …

A comparison of centrality measures and their role in controlling the spread in epidemic networks Open
The ranking of nodes in a network according to their centrality or ``importance'' is a classic problem that has attracted the interest of different scientific communities in the last decades. The COVID-19 pandemic has recently rejuvenated …

Resolving the enigma of Iquitos and Manaus: A modeling analysis of multiple COVID-19 epidemic waves in two Amazonian cities Open
The two nearby Amazonian cities of Iquitos and Manaus endured explosive COVID-19 epidemics and may well have suffered the world’s highest infection and death rates over 2020, the first year of the pandemic. State-of-the-art epidemiological…

Rapid global spread of variants of concern of SARS-CoV-2 Open
The Omicron variant has much higher transmission potential compared with the Delta variant, and the Delta variant has higher transmission potential compared with the pre-Delta VOCs.

Switching Checkerboards Open
In order to study $\mathbf{M}(R,C)$, the set of binary matrices with fixed row and column sums $R$ and $C$, we consider sub-matrices of the form $\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}$ and $\begin{pmatrix} 0 & 1 \\ 1 & 0 \end{pmatri…

Modelling COVID-19 vaccine breakthrough infections in highly vaccinated Israel—The effects of waning immunity and third vaccination dose Open
In August 2021, a major wave of the SARS-CoV-2 Delta variant erupted in the highly vaccinated population of Israel. The transmission advantage of the Delta variant enabled it to replace the Alpha variant in approximately two months. The ou…

Rapid global spread of Variant of Concern of SARS-CoV-2 Open
In this work, we show the spatiotemporal spread and replacement of different Variant of Concern (VOC) of SARS-COV-2. We define a metric to quantify the spread speed of each COV. We discuss the basic reproductive number of these VOC’s and p…

Evaluation of Effectiveness of Global COVID-19 Vaccination Campaign Open
To model estimated deaths averted by COVID-19 vaccines, we used state-of-the-art mathematical modeling, likelihood-based inference, and reported COVID-19 death and vaccination data. We estimated that >1.5 million deaths were averted in 12 …

The immune evasion ability of Delta variant is comparable to that of Beta variant in South Africa Open
Background The high immune evasion ability of SARS-COV-2 Omicron variant surprised the world and appears to be far stronger than any previous variant. Previous to Omicron it has been difficult to assess and compare immune evasion ability o…

A machine learning method for estimating the probability of presence using presence‐background data Open
Estimating the prevalence or the absolute probability of the presence of a species from presence‐background data has become a controversial topic in species distribution modelling. In this paper, we propose a new method by combining both s…

Percolation of heterogeneous flows uncovers the bottlenecks of infrastructure networks Open
Whether it be the passengers’ mobility demand in transportation systems, or the consumers’ energy demand in power grids, the primary purpose of many infrastructure networks is to best serve this flow demand. In reality, the volume of flow …
