Implementing a Central Bank Issued Digital Currency with Economic Implications Considerations

International Journal of Islamic Economics and Finance, 2020
A central bank-issued digital currency (CBDC) could solve the volatility of a privately-issued cryptocurrency as well as keep intact its potential benefits.

The γ Dor stars as revealed by Kepler: A key to reveal deep-layer rotation in A and F stars

EPJ Web of Conferences, 2017
The γ Dor pulsating stars present high-order gravity modes, which make them important targets in the intermediate-and low-mass main-sequence region of the Hertzsprung-Russell diagram. Whilst we have only access to rotation in the envelope of the Sun, the

LATIS: The Stellar Mass–Metallicity Relation of Star-forming Galaxies at z ∼ 2.5

The Astrophysical Journal, 2023
We present the stellar mass–stellar metallicity relation for 3491 star-forming galaxies at 2 ≲ z ≲ 3 using rest-frame far-ultraviolet spectra from the Ly α Tomography IMACS Survey (LATIS).

Stellar coronae [PDF]

Symposium - International Astronomical Union, 1997
The last two decades have seen the emergence of a new field in stellar astrophysics, the study of stellar coronae mostly in X-ray domain. With the advent of soft X-ray imagery X-ray emission was found from many thousands of solar-like stars. I will summarize the most important findings of X-ray surveys of late type stars and put the results in the ...

RNP interfaces as regulatory “active sites”: a repurposing strategy for small molecules targeting viral 5′-untranslated regions

Frontiers in Molecular Biosciences
RNA-protein (RNP) complexes regulate nearly every stage of gene expression and play central roles in viral infection and human disease. Despite decades of research, relatively few small molecules (SMs) have been shown to modulate RNP assemblies with ...

PLATO: PSF modelling using a micro-scanning technique

EPJ Web of Conferences, 2015
The PLATO space mission is designed to detect telluric planets in the habitable zone of solar type stars, and simultaneously characterise the host star using ultra high precision photometry. The photometry will be performed on board using weighted masks.

Stellar Chromospheres [PDF]

International Astronomical Union Colloquium, 1980
Important progress in our understanding of stellar chromospheres has occurred in the past few years as a result of new observations, developments in spectral line formation theory, and the application of that theory to the construction of detailed model chromospheres.

Stellar Chromospheric Variability

, 2021
Cool stars with convective envelopes of spectral types F and later tend to exhibit magnetic activity throughout their atmospheres. The presence of strong and variable magnetic fields is evidenced by photospheric starspots, chromospheric plages and ...

A Few Years Later: Revisiting Period Variations of Eclipsing Binaries in the Northern Continuous Viewing Zone of TESS

Universe
In our previous analysis of the eclipse timing variation patterns of eclipsing binaries located in and near the Northern Continuous Viewing Zone (NCVZ) of the TESS space telescope, 135 hierarchical triple star candidates were found.

Early assembly of the most massive galaxies [PDF]

, 2009
The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).
