Hydrologic Whiplash in the Mississippi River Basin: Mechanisms and Projections

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Volatility and unpredictability of hydroclimate systems stresses planning and risk management. Notably, the rapid transition between periods of high and low streamflow, known as hydrologic whiplash, is gaining attention worldwide. Yet the specific mechanisms driving hydrologic whiplash events, and how they differ from singular events, remain ...

Strategic materials and state capacity in Renaissance Italy: The economic policies of ‘Roman saltpetre’ procurement

open access: yesThe Economic History Review, Volume 79, Issue 2, Page 757-780, May 2026.
Abstract Demonstrating the existence of a soaring demand for strategic materials in fifteenth‐century Rome, the article pioneers research in the late medieval trade in saltpetre, the irreplaceable, rare component of gunpowder, indispensable for waging war following the diffusion of artillery technology.

Numerical simulation of oblique towing test

open access: yesAnnals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2016
During the design of a ship, manoeuvrability performance should be measured in order to ensure course keeping and turning ability. In order to find out these characteristics, the numerical simulation of the Oblique Towing Test (OTT) has been developed ...

From External Governance to Energy Diplomacy: The European Pursuit of Green Hydrogen

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 3, Page 1135-1159, May 2026.
Abstract Following the Russian invasion of Ukraine, the European Union (EU) and its Member States are faced with the double imperative of ensuring energy security whilst reaching decarbonisation goals. A number of authors have suggested that we are observing a geopolitical Commission that is shifting to more active ‘energy diplomacy’, as opposed to its

An Improved A-Star Algorithm Considering Water Current, Traffic Separation and Berthing for Vessel Path Planning

open access: yesApplied Sciences, 2019
A traditional A-Star (A*) algorithm generates an optimal path by minimizing the path cost. For a vessel, factors of path length, obstacle collision risk, traffic separation rule and manoeuvrability restriction should be all taken into account for path ...
