ON CONCEPTS AS HISTORICAL FORMS
History and Theory, EarlyView.ABSTRACT What are the consequences of holding fast to the axiom that words are not the same thing as concepts? This article explores some of them in relation to the tensions between two different but overlapping approaches to the history of concepts: philology and computationally informed historical semantics. The methods utilized were developed in the

Detecting supernovae neutrino with Earth matter effect
, 2016 We study Earth matter effect in oscillation of supernovae neutrinos. We show that detecting Earth matter effect gives an independent measurement of spectra of supernovae neutrinos, i.e. the flavor difference of the spectra of supernovae neutrinos.

Molecular Ecology, EarlyView.ABSTRACT Population declines may have long‐term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of ...

An Accelerating Universe without Lambda: Delta Gravity Using Monte Carlo
Universe, 2019 A gravitational field model based on two symmetric tensors, g μ ν and g ˜ μ ν , is studied, using a Markov Chain Monte Carlo (MCMC) analysis with the most updated catalog of SN-Ia.

Hamas's October 7 Attack: Analysis of an “Antagonistic” Crisis
Public Administration Review, EarlyView.ABSTRACT The aim of the article is to interpret the Hamas attack of October 7, 2023 in light of crisis management theories, seeking to draw from this event some general lessons about the nature of crises, their determinants, and how they are managed. More specifically, the article addresses three questions: (1) Why did Israel underestimate the warning ...

Constraining the minimally extended varying speed of light model using time dilations
Frontiers in Astronomy and Space SciencesThe Robertson–Walker (RW) metric, derived from the cosmological principle and Weyl’s postulate, characterizes the ΛCDM cosmological model. Traditionally, in this framework, the assumption of a constant speed of light leads to specific cosmological time ...

Revealing the True Nature of Hen 2-428
Galaxies, 2018 The nucleus of Hen 2-428 is a short orbital period (4.2 h) spectroscopic binary, whose status as potential supernovae type Ia progenitor has raised some controversy in the literature.

The Anatomical Record, Volume 308, Issue 12, Page 3197-3229, December 2025.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.
