The Political Is Profitable: Political Controversy and Litigation Crowdfunding Outcomes

open access: yesPolitics &Policy, Volume 53, Issue 3, June 2025.
ABSTRACT Little research has been conducted on litigation crowdfunding, including how links to politically controversial causes may influence fundraising success. This study collected 500 crowdfunding campaigns for legal expenses initiated between December 27, 2022, and June 1, 2023, and 50 litigation campaigns with the highest fundraising totals on ...

AGN Observations with the MAGIC Telescope [PDF]

open access: yesScience with the New Generation of High Energy Gamma-Ray Experiments, 2007
MAGIC is presently the imaging atmospheric Cherenkov telescope with the largest reflecting surface and the lowest energy threshold. MAGIC concluded its first year of regular observation in April 2006. During this period and the preceding commissioning phase, 25 Active Galactic Nuclei have been observed and VHE gamma-ray emission has been confirmed by 4

Blueprint for a Universal Theory of Learning to Read: The Combinatorial Model

open access: yesReading Research Quarterly, Volume 60, Issue 2, April/May/June 2025.
The Reading Tree. Abstract In this essay, I outline some of the essential ingredients of a universal theory of reading acquisition, one that seeks to highlight commonalities while embracing the global diversity of languages, writing systems, and cultures.

Characterization of Deformation and Failure of Fomes fomentarius Hymenium by Synchrotron Phase‐Contrast Enhanced Micro‐Computed Tomography, In situ Compression Testing and Three‐Dimensional Optical Flow

open access: yesSmall Structures, Volume 6, Issue 4, April 2025.
In situ compression tests on the honeycomb structure of Fomes fomentarius hymenium under parallel and transverse loading show that parallel loading results in small and uniform displacements due to hyphae orientation along the honeycomb. Damage occurs through plastic buckling and delamination of tube walls in dry samples.

Sub-GeV Gamma Rays from Nearby Seyfert Galaxies and Implications for Coronal Neutrino Emission

open access: yesThe Astrophysical Journal Letters
Recent observations of high-energy neutrinos by IceCube and gamma rays by the Fermi Large Area Telescope (LAT) and the MAGIC telescope have suggested that neutrinos are produced in gamma-ray opaque environments in the vicinity of supermassive black holes.

Artificial Intelligence and Creativity

open access: yesPhilosophy Compass, Volume 20, Issue 3, March 2025.
ABSTRACT The question of whether machines can be creative has been at the centre of debates among scholars and practitioners well before the inception of artificial intelligence (AI) as a recognised field of research. This paper reviews how some of the key thinkers in the fields of creativity and AI have approached this question, contextualising their ...

Cloud Detection and Prediction with All Sky Cameras

open access: yesEPJ Web of Conferences, 2017
Atmospheric monitoring is a field of special importance for astroparticle physics, especially for Imaging Atmospheric Cherenkov Telescopes (IACTs) as clouds will absorb and scatter the Cherenkov photons of air showers.

The Meaning of Quasi‐Simultaneous X‐Rays and Gamma‐Ray Observations of RS Oph in Outburst

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Shocks in novae outbursts are ubiquitous, but in symbiotic novae, they are particularly powerful, probably because of the surrounding red giant wind. The recurrent nova RS Oph is the best example of this phenomenon. The presence of shocked plasma in outburst was inferred from optical spectra, and it was confirmed by X‐ray observations since ...
