Indigenous resurgence in the Blue Economy: Relational values to guide kelp mariculture

People and Nature, EarlyView.
Abstract Decisions about how to use ocean spaces are increasingly attuned to issues of social equity, environmental sustainability and climate resilience, yet often bypass local governance, knowledge, values and thus objectives. To inform future decisions about kelp harvest and mariculture activities on the west coast of Canada, we co‐designed research

Status Report on the Chicago-Carnegie Hubble Program (CCHP): Measurement of the Hubble Constant Using the Hubble and James Webb Space Telescopes

The Astrophysical Journal
We present the latest results from the Chicago-Carnegie Hubble Program to measure the Hubble constant, using data from the James Webb Space Telescope (JWST). The overall program aims to calibrate three independent methods: (1) tip of the red giant branch

Towards an Observational Appraisal of String Cosmology

, 2011
We review the current observational status of string cosmology when confronted with experimental datasets. We begin by defining common observational parameters and discuss how they are determined for a given model.

The Apparent Fractal Conjecture [PDF]

, 1999
This short communication advances the hypothesis that the observed fractal structure of large-scale distribution of galaxies is due to a geometrical effect, which arises when observational quantities relevant for the characterization of a cosmological ...

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, EarlyView.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Detecting the 21 cm Signal from the Cosmic Dark Ages

The Astrophysical Journal
The cosmic “dark ages” is the period between the last scattering of the cosmic microwave background and the appearance of the first luminous sources, spanning redshifts 1100 ≳  z  ≳ 30.

The Truncated Lognormal Distribution as a Luminosity Function for SWIFT-BAT Gamma-Ray Bursts

Galaxies, 2016
The determination of the luminosity function (LF) in Gamma ray bursts (GRBs) depends on the adopted cosmology, each one characterized by its corresponding luminosity distance.

Distance Duality Test: The Evolution of Radio Sources Mimics a Nonexpanding Universe

The Astrophysical Journal Letters, 2023
Distance duality relation (DDR) marks a fundamental difference between expanding and nonexpanding universes, as an expanding metric causes angular diameter distance smaller than luminosity distance by an extra factor of (1 + z ). Here we report a test of

Was the Inca Economy Based on “Protomoney”? Or, Why Accounting Systems Should Not Be Conflated With Concepts of Exchange Value

Economic Anthropology, EarlyView.
ABSTRACT The khipu knotted string records in the ancient Andes were accounting systems, but they did not indicate any concepts of commensurability or exchange value. They were not incipient money; instead, monetized commerce appears to have predated the economic organization of the Inca society. The article begins by tracing the emergence of coinage in
