Geometric persistence and distributional trends in worldwide terrorism
Nick James, Max Menzies, James Chok +2
This paper introduces new methods for studying the prevalence of terrorism around the world and over time. Our analysis treats spatial prevalence of terrorism, the changing profile…
Distributional trends in the generation and end-use sector of low-carbon hydrogen plants
Nick James, Max Menzies
This paper uses established and recently introduced methods from the applied mathematics and statistics literature to study trends in the end-use sector and capacity of low-carbon…
Dual-domain analysis of gun violence incidents in the United States
Nick James, Max Menzies
This paper applies new and recently introduced approaches to study trends in gun violence in the United States. We use techniques in both the time and frequency domain to provide a…
Collective infectivity of the pandemic over time and association with vaccine coverage and economic development
Nick James, Max Menzies
This paper uses new and existing methods to study collective trends across countries throughout the pandemic, with a focus on the multivariate time series of reproduction numbers a…
Global and regional changes in carbon dioxide emissions: 1970-2019
Nick James, Max Menzies
We introduce new frameworks to study spatio-temporal patterns in carbon dioxide emissions, demographic trends and economic patterns across 50 countries over the past 50 years. Our…
Estimating a continuously varying offset between multivariate time series with application to COVID-19 in the United States
Nick James, Max Menzies
This paper introduces new methods to track the offset between two multivariate time series on a continuous basis. We then apply this framework to COVID-19 counts on a state-by-stat…
Spatio-temporal trends in the propagation and capacity of low-carbon hydrogen projects
Nick James, Max Menzies
This paper uses established and recently introduced methods from the applied mathematics and statistics literature to study trends in the propagation and capacity of low-carbon hyd…
In search of peak human athletic potential: A mathematical investigation
Nick James, Max Menzies, Howard Bondell
This paper applies existing and new approaches to study trends in the performance of elite athletes over time. We study both track and field scores of men and women athletes on a y…
Comparing the dynamics of COVID-19 infection and mortality in the United States, India, and Brazil
Nick James, Max Menzies, Howard Bondell
This paper compares and contrasts the spread and impact of COVID-19 in the three countries most heavily impacted by the pandemic: the United States (US), India and Brazil. All thre…
Understanding spatial propagation using metric geometry with application to the spread of COVID-19 in the United States
Nick James, Max Menzies, Howard Bondell
This paper introduces a novel approach to spatio-temporal data analysis using metric geometry to study the propagation of COVID-19 across the United States. Using a geodesic Wasser…
Efficiency of communities and financial markets during the 2020 pandemic
Nick James, Max Menzies
This paper investigates the relationship between the spread of the COVID-19 pandemic, the state of community activity, and the financial index performance across 20 countries. Firs…
Trends in COVID-19 prevalence and mortality: a year in review
Nick James, Max Menzies
This paper introduces new methods to study the changing dynamics of COVID-19 cases and deaths among the 50 worst-affected countries throughout 2020. First, we analyse the trajector…
COVID-19 second wave mortality in Europe and the United States
Nick James, Max Menzies, Peter Radchenko
This paper introduces new methods to analyze the changing progression of COVID-19 cases to deaths in different waves of the pandemic. First, an algorithmic approach partitions each…
COVID-19 in the United States: Trajectories and second surge behavior
Nick James, Max Menzies
This paper introduces a mathematical framework for determining second surge behavior of COVID-19 cases in the United States. Within this framework, a flexible algorithmic approach…
Association between COVID-19 cases and international equity indices
Nick James, Max Menzies
This paper analyzes the impact of COVID-19 on the populations and equity markets of 92 countries. We compare country-by-country equity market dynamics to cumulative COVID-19 case a…
