The Political Is Profitable: Political Controversy and Litigation Crowdfunding Outcomes

Politics &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 ...

Study of Angular Resolution Using Imaging Atmospheric Cherenkov Technique

Universe
Angular resolution is crucial for the detailed study of gamma-ray sources and current Cherenkov telescopes (e.g., HESS, MAGIC, and VERITAS) that operate below tens of TeV.

Atmospheric Monitoring for the MAGIC Telescopes

, 2014
The monitoring of the atmosphere is very relevant for Imaging Atmospheric Cherenkov Telescopes. Adverse weather conditions (strong wind, high humidity, etc.) may damage the telescopes and must therefore be monitored continuously to guarantee a safe operation, and the presence of clouds and aerosols affects the transmission of the Cherenkov light and ...

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

Reading 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

Small 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.

Artificial Intelligence and Creativity

Philosophy 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 ...

Lorentz Invariance Violation from Gamma-Ray Bursts

The Astrophysical Journal
Lorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energy scale as E _LV ≃ 3.60 × 10 ^17 GeV using Fermi Gamma-ray Space Telescope

Pre-burst neutrinos of gamma-ray bursters accompanied by high-energy photons

Physics Letters B, 2021
Previous researches on high-energy neutrino events from gamma-ray bursters (GRBs) suggest a neutrino speed variation v(E)=c(1±E/ELVν) with ELVν=(6.4±1.5)×1017 GeV, together with an intrinsic time difference Δtin=(−2.8±0.7)×102 s, which means that high ...

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

Astronomische 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 ...
