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 ...

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 $I(n)=\frac{σ(n)}{n}$.

Abundance of Infinite Switching
SIAM Journal on Applied Dynamical Systems, 2023 Abstract. We describe a class of vector fields exhibiting abundant switching near a heteroclinic network: for every neighborhood of the network and every infinite admissible path, the set of initial conditions within the neighborhood that follows the path has positive Lebesgue measure.

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.

Externalities, scarcity, and abundance
Frontiers in Research Metrics and Analytics, 2022 IntroductionDo externalities work and matter differently in a world of scarcity vs. a world of abundance? In this article, we critically examine the economic phenomena of externalities. The concept of externality, an important idea in economics and law, is useful in exploring the complex and dynamic relationships between resource supply and human ...

Frontiers in Research Metrics and Analytics, 2022 With technological advance has come the possibility of a new era of abundance. Technologies like 3D printing and robotics promise to lower the costs of production and distribution of goods and services, presumably making these goods and services readily available to those across income and wealth spectrums. This undoubtedly is a good thing.

Radial Gradients of Abundances [PDF]
Astrophysics and Space Science, 2002 We have computed a set of multiphase chemical evolution models in which the radial mass distribution of each theoretical galaxy is calculated using the Universal Rotation Curve from Persic, Salucci & Steel (1996). We obtain the chemical evolution for galaxies of different masses and morphological types by changing the efficiencies to form molecular

The Interaction Between Accretion from the Interstellar Medium and Accretion from the Evolved Binary Component in Barium Stars [PDF]
Journal of Astronomy and Space Sciences, 2018 The reanalysis of the previously published abundance pattern of mild barium star HD202109 (ζ Cyg) and the chemical compositions of 129 thin disk barium stars facilitated the search for possible correlations of different stellar parameters with second ...

Atomic diffusion in the atmosphere of Feige 86
Open Astronomy, 2017 We have revisited the ultraviolet and optical spectra of the blue horizontal branch star Feige 86. The new analysis finds the star cooler and more compact than previously determined. The IUE spectrum of Feige 86 holds numerous unidentified spectral lines
