An accelerated framework for high‐resolution X‐ray holographic reconstruction

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 454-466, March 2026.
HiHolo, a high‐performance CUDA‐MPI software framework for X‐ray holographic reconstruction, achieves performance improvement over existing solutions while introducing three enhanced iterative algorithms that effectively reduce artifacts and improve spatial resolution in propagation‐based phase contrast imaging.X‐ray propagation‐based phase contrast ...

High‐energy synchrotron X‐ray multimodal computed tomography: enabling multiscale materials characterization at NSLS‐II

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 531-542, March 2026.
The development of multimodal X‐ray computed tomography capabilities, including imaging, fluorescence, diffraction, and scattering, at the 28‐ID‐2 beamline of the National Synchrotron Light Source II is described.We report the commissioning of a multimodal computed tomography experimental setup at the 28‐ID‐2 (XPD) beamline of the National Synchrotron ...

Why Interest Groups With Divergent Goals Collaborate: Evidence From Climate Regulation

open access: yesEconomics &Politics, Volume 38, Issue 1, Page 46-61, March 2026.
ABSTRACT Why do interest groups with contrasting interests and policy goals work together? I present a theory of collaborative policy production and show that interest groups can achieve higher policy gains through collaboration, even though their ideal policy goals may diverge significantly.

Multivariate representations of univariate marked Hawkes processes

open access: yesScandinavian Journal of Statistics, Volume 53, Issue 1, Page 140-174, March 2026.
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 ...
