Frontiers in Research Metrics and Analytics, 2022 The technology driven post-scarcity society is upon us. Ubiquitous technologies are eradicating scarcity in many industries. These macroscopic system trends are causing our economy to transition from relative scarcity to relative abundance. For many people in the world however, in both developed, developing, and underdeveloped countries, the notion of ...

Magellanic Clouds Cepheids: Thorium Abundances [PDF]
Journal of Astronomy and Space Sciences, 2018 The analysis of the high-resolution spectra of 31 Magellanic Clouds Cepheid variables enabled the identification of thorium lines. The abundances of thorium were found with spectrum synthesis method. The calculated thorium abundances exhibit correlations

The Record-Warm Barents Sea and 0-Group Fish Response to Abnormal Conditions
Frontiers in Marine Science, 2020 The Barents Sea is a nursery area for many commercially and ecologically important fish stocks, and this whole region is presently subject to rapid climatic change from a cold period in the 1980s to a record warm period in the latest decade, with a peak ...

Solar Elemental Abundances [PDF]
Oxford Research Encyclopedia of Planetary Science, 2019 Solar elemental abundances, or solar system elemental abundances, refer to the complement of chemical elements in the entire Solar System. The Sun contains more than 99% of the mass in the solar system and therefore the composition of the Sun is a good ...

Measuring Abundance with Abundancy Index
, 2021 A positive integer $n$ is called perfect if $ σ(n)=2n$, where $σ(n)$ denote the sum of divisors of $n$. In this paper we study the ratio $\frac{σ(n)}{n}$. We define the function Abundancy Index $I:\mathbb{N} \to \mathbb{Q}$ with $I(n)=\frac{σ(n)}{n}$.

Indirect Measurements of n- and p-Induced Reactions of Astrophysical Interest on Oxygen Isotopes
Frontiers in Astronomy and Space Sciences, 2020 Observations of abundances and isotopic ratio determinations in stars yield powerful constraints on stellar models. In particular, the oxygen isotopic ratios are of particular interest because they are affected not only by nucleosynthesis but also by ...

Accuracy and Precision of Industrial Stellar Abundances [PDF]
Annual Review of Astronomy and Astrophysics, 2018 There has been an incredibly large investment in obtaining high-resolution stellar spectra for determining chemical abundances of stars. This information is crucial to answer fundamental questions in astronomy by constraining the formation and evolution ...

On Generalised Abundance, II [PDF]
Peking Mathematical Journal, 2019 The goal of this paper is to make a striking connection between several central conjectures in algebraic geometry: the Nonvanishing Conjecture, the Abundance Conjecture and the Semiampleness Conjecture for nef line bundles on K -trivial varieties.
