On goodness‐of‐fit testing for self‐exciting point processes

Scandinavian Journal of Statistics, EarlyView.
Abstract Despite the wide usage of parametric point processes in theory and applications, a sound goodness‐of‐fit procedure to test whether a given parametric model is appropriate for data coming from a self‐exciting point process has been missing in the literature.

Multivariate representations of univariate marked Hawkes processes

Scandinavian Journal of Statistics, EarlyView.
Abstract Univariate marked Hawkes processes are used to model a range of real‐world phenomena including earthquake aftershock sequences, contagious disease spread, content diffusion on social media platforms, and order book dynamics. This paper illustrates a fundamental connection between univariate marked Hawkes processes and multivariate Hawkes ...

Variable selection via thresholding

Scandinavian Journal of Statistics, EarlyView.
Abstract Variable selection comprises an important step in many modern statistical inference procedures. In the regression setting, when estimators cannot shrink irrelevant signals to zero, covariates without relationships to the response often manifest small but nonzero regression coefficients.

Beyond Climate Security: Reframing the Climate‐War Nexus Through Bataille's General Economy

Antipode, Volume 58, Issue 2, March 2026.
Abstract The spectre of resource scarcity as a cause of war is dominant in discussions about potential links between climate change and armed conflict. Via engagement with Georges Bataille's theory of a general economy of the biosphere, this article conceptualises the relationship between climate change and war by focusing on resource excess as a ...

Photonic QPU With Coherent States for Reversible Quantum Logic

Annalen der Physik, Volume 538, Issue 2, February 2026.
A photonic Quantum Processing Unit X (QPU X) design leveraging coherent‐state qubits and linear optics probabilistically implements fundamental logical gates‐including AND, OR, C‐NOT, C¯$\bar{C}$‐NOT, Toffoli (C2${\rm C}^2$‐NOT), and Fredkin (C‐SWAP)‐with success probabilities up to 1/4 for simpler gates.
