Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

Civility, honour and male aggression in early modern English jestbooks

open access: yesGender &History, EarlyView.
Abstract This article discusses the comical representation of inter‐male violence within early modern English jestbooks. It is based on a rigorous survey of the genre, picking out common themes and anecdotes, as well as discussing their reception and sociable functions. Previous scholarship has focused on patriarchs, subversive youths and impoliteness.

A (2 + 1)-Dimensional Integrable Breaking Soliton Equation and Its Algebro-Geometric Solutions

open access: yesMathematics
A new (2 + 1)-dimensional breaking soliton equation with the help of the nonisospectral Lax pair is presented. It is shown that the compatible solutions of the first two nontrivial equations in the (1 + 1)-dimensional Kaup–Newell soliton hierarchy ...

Dynamic Keynesian Model of Economic Growth with Memory and Lag

open access: yesMathematics, 2019
A mathematical model of economic growth with fading memory and continuous distribution of delay time is suggested. This model can be considered as a generalization of the standard Keynesian macroeconomic model.

Abel's Integral Equation as a Convolution Transform [PDF]

open access: yesProceedings of the American Mathematical Society, 1956
the first equation to be treated and solved as an integral equation, has an extensive literature, dealing on the one hand with properties of the functions involved, and on the other hand with the solution, and conditions for solubility of the equation. In the first category one might cite, in the modern spirit, the memoirs of Hardy [1, pp.

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

On the composition conjectures

open access: yesElectronic Journal of Differential Equations, 2003
We describe a class of polynomials that satisfy the composition conjecture for the moments. We also show that the composition conjecture for the moments is not weaker than the composition conjecture for a center.

Multiplying Elements of Fragmentation? Polycentrism, the Launcher Crisis and the Future of Europe in Space

open access: yesGlobal Policy, EarlyView.
ABSTRACT This article explores the current controversies surrounding the European Ariane launcher and its implications for the future of European space governance. The Ariane program, historically a symbol of European technopolitical integration, faces mounting challenges due to delays, rising costs and increasing competition from private actors like ...

Comparing Movement Patterns and Physical Function Between Chronic Low Back Pain Patients With Nociplastic and Nociceptive Pain Categories. [PDF]

open access: yesJOR Spine
Are differences in perceived disability between nociceptive and nociplastic cLBP patients reflected in actual movement patterns or in patients' perceived functional ability? Despite worse patient‐reported disability, primarily nociplastic patients did not exhibit worse biomechanical function when compared to primarily nociceptive patients.
