Photochemical model of impact-produced lunar atmosphere [PDF]

Proceedings of the Fourth International Conference on the Exploration and Utilisation of the Moon, p. 175 - 178, the Netherlands, Noordwijk, 10-14 July 2000, 2002
The Lunar Prospector mission detected hydrogen-containing compounds in the lunar polar regions. We have considered the comet hypothesis of the origin of polar volatiles on the Moon. In the present paper we use our model of a comet impact with photochemical processes to be included to estimate chemical composition of volatiles which can be captured by ...

Condensation and the Volatility Trend of the Earth [PDF]

arXiv
This article describes condensation of the elements and use of condensation temperatures (Tcond) to interpret the volatility trend of the Earth. Major points are: (1) a listing of updated 50% Tcond for all natural elements and Pu at 1e-2 to 1e-8 bar pressure for solar composition matter.

Prediction of Cryptocurrency Prices through a Path Dependent Monte Carlo Simulation [PDF]

arXiv
In this paper, our focus lies on the Merton's jump diffusion model, employing jump processes characterized by the compound Poisson process. Our primary objective is to forecast the drift and volatility of the model using a variety of methodologies. We adopt an approach that involves implementing different drift, volatility, and jump terms within the ...

Impact of insect herbivory on plant stress volatile emissions from trees: A synthesis of quantitative measurements and recommendations for future research

Atmospheric Environment: X, 2020
Plants, and particularly trees, are the largest source of atmospheric volatile organic compounds globally. Insect herbivory alters plant volatile emission rates and the types of compounds that are emitted.

AtmoSpec -- A Tool to Calculate Photoabsorption Cross-Sections for Atmospheric Volatile Organic Compounds [PDF]

arXiv
Characterizing the photolysis processes undergone by transient volatile organic compounds in the troposphere requires the knowledge of their photoabsorption cross-section - quantities often challenging to determine experimentally, particularly due to the reactivity of these molecules. We present a computational tool coined AtmoSpec, which can predict a
