China's Export Surge and the Persistence of Machinery Competitiveness: Panel Evidence From 25 Countries

open access: yesThe World Economy, EarlyView.
ABSTRACT China's rapid ascent as a global machinery exporter raises fundamental questions about competitive resilience of incumbent economies. This paper examines whether China's gains in revealed comparative advantage (RCA) are associated with declining competitive positions among 24 incumbent economies and whether such changes coincide with ...

Uncertainty Quantification and Attribution for Resilient Infrastructure Systems

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Infrastructure resilience is critical for maintaining the delivery of essential services to society. However, although computational modelling is integral to infrastructure management, infrastructure model outputs are conditional on a range of uncertain assumptions, both in the present day and under future climate change.

Pump as Turbine - Symmetry Prediction Method for Pump as Turbine Characteristics

open access: yes, 2018
As a cheap and available source of renewable energy, regular centrifugal pumps may be run in reverse to act as hydro turbines. Pumps as turbines (PAT) are especially relevant for isolated rural areas, or in developing countries, where efficiency is not necessarily the highest priority.

From Mine to Meal: How Critical Minerals Shape the Future of Food

open access: yesFood and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Food systems are increasingly recognised as material‐intensive socio‐technical systems rather than solely biological or land‐based systems. Yet, critical minerals, which underpin both agricultural inputs and emerging clean energy technologies, remain an under‐recognised determinant of modern food security.
