Semi-strong Efficient Market of Bitcoin and Twitter: an Analysis of Semantic Vector Spaces of Extracted Keywords and Light Gradient Boosting Machine Models
Fang Wang, Marko Gacesa
This study extends the examination of the Efficient-Market Hypothesis in Bitcoin market during a five year fluctuation period, from September 1 2017 to September 1 2022, by analyzi…
Elastic and inelastic cross sections for C+CO and C+CO scattering at superthermal energies
Marko Gacesa
We report elastic and inelastic cross sections for fast superthermal C() and C() atoms scattering on CO. The cross sections were computed using q…
A quantum-mechanical investigation of O() + CO scattering cross sections at superthermal collision energies
Sanchit Chhabra, Marko Gacesa, Malathe S. Khalil +2
The kinetics and energetic relaxation associated with collisions between fast and thermal atoms are of fundamental interest for escape and therefore also for the evolution of the M…
Photoassociation of ultracold long-range polyatomic molecules
Marko Gacesa, Jason N. Byrd, Jonathan Smucker +2
We explore the feasibility of optically forming long-range tetratomic and larger polyatomic molecules in their ground electronic state from ultracold pairs of polar molecules align…
O()+CO scattering cross sections at superthermal collision energies for planetary aeronomy
Marko Gacesa, Robert J. Lillis, Kevin J. Zahnle
We report new elastic and inelastic cross sections for O()+CO scattering at collision energies from 0.03 to 5 eV, of major importance to O escape from Mars, Venus, and CO$…
Impacts of Quantum Chemistry Calculations on Exoplanetary Science, Planetary Astronomy, and Astrophysics
Der-you Kao, Marko Gacesa, Renata M. Wentzcovitch +26
Several of NASA missions (TESS, JWST, WFIRST, etc.) and mission concepts (LUVOIR, HabEx, and OST) emphasize the exploration and characterization of exoplanets, and the study of the…
Strange messenger: A new history of hydrogen on Earth, as told by Xenon
Kevin J. Zahnle, Marko Gacesa, David C. Catling
Atmospheric xenon is strongly mass fractionated, the result of a process that apparently continued through the Archean and perhaps beyond. Previous models that explain Xe fractiona…
Charge transfer in ultracold gases via Feshbach resonances
Marko Gacesa, Robin Côté
We investigate the prospects of controlling charge-exchange in ultracold collisions of heteroisotopic combinations of atoms and ions of the same element. The treatment, readily app…
