Latin American Policy, Volume 16, Issue 4, December 2025.ABSTRACT In recent years, video assistant referee systems have been increasingly used to correct unfair decisions in sports. Similarly, I argue that constitutional referendums play a corrective role in hybrid or competitive authoritarian regimes, where the electoral referee is biased and the government enjoys unfair advantages.

Adiabatic pumping solutions in global AdS
Journal of High Energy Physics, 2017 We construct a family of very simple stationary solutions to gravity coupled to a massless scalar field in global AdS. They involve a constantly rising source for the scalar field at the boundary and thereby we name them pumping solutions.

Quasi‐Constant Time Gap in Multiple Rings of Elves
Earth and Space Science, Volume 12, Issue 10, October 2025.Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

Boletim do Museu Paraense Emílio Goeldi. Ciências Humanas, 2019 Resumo Em Rikbaktsa (Macro-Jê), as partículas constituem uma classe léxica, ao lado de advérbios e posposições. Em geral, as partículas são descritas como elementos invariáveis; nesta língua, entretanto, há dois conjuntos de partículas, um marcando ...

American Anthropologist, Volume 127, Issue 3, Page 517-528, September 2025.ABSTRACT This article examines the contested status of “sign language” in Singapore by exploring deaf people's experiences of the “Mother Tongues”—the state's designation for the official languages of Mandarin, Malay, and Tamil—with a particular focus on the relationships that deaf Chinese Singaporeans have with Mandarin.

FASEB BioAdvances, Volume 7, Issue 7, July 2025.By integrating single‐cell RNA‐seq data, this study reveals dynamic changes in gene expression, alternative splicing, and isoform switching during human early embryonic development (E3–E7). These regulatory layers are complementary and stage‐specific, with sex‐dependent differences especially evident at E3.

Modelo de quarks e sistemas multiquarks [PDF]
Revista Brasileira de Ensino de Física, 2007 A descoberta de muitas partículas, especialmente nos anos 50, com o surgimento de novos aceleradores, causou a busca por um modelo que descrevesse de forma simplificada o conjunto de partículas conhecidas.

Small free field inflation in higher curvature gravity
Journal of High Energy Physics, 2021 Within General Relativity, a minimally coupled scalar field governed by a quadratic potential is able to produce an accelerated expansion of the universe provided its value and excursion are larger than the Planck scale.
