Subsurface exolife [PDF]

open access: yesInternational Journal of Astrobiology, 2018
AbstractWe study the prospects for life on planets with subsurface oceans, and find that a wide range of planets can exist in diverse habitats with ice envelopes of moderate thickness. We quantify the energy sources available to these worlds, the rate of production of prebiotic compounds, and assess their potential for hosting biospheres. Life on these

Subsurface Texture Mapping [PDF]

open access: yesIEEE Computer Graphics and Applications, 2006
Subsurface scattering within translucent objects is a complex phenomenon. Designing and rendering this kind of material requires a faithful description of their aspects as well as a realistic simulation of their interaction with light. This paper presents an efficient rendering technique of multilayered translucent objects.

Separable subsurface scattering [PDF]

open access: yesACM SIGGRAPH 2012 Computer Animation Festival, 2012
Due to the parallel advances in hardware and software, graphics in games are continuously improving. Still, for a 60-fps game, everything contained in a frame must be computed in just about 16 milliseconds. Given this tight time budget, certain effects cannot be computed and are simply not simulated, sacrificing realism to reallocate resources to other

Physics-Informed Neural Networks for Multiphysics Data Assimilation with Application to Subsurface Transport [PDF]

open access: yesAdvances in Water Resources, 2019
Data assimilation for parameter and state estimation in subsurface transport problems remains a significant challenge due to the sparsity of measurements, the heterogeneity of porous media, and the high computational cost of forward numerical models.

Widespread occurrence of anomalous C-band backscatter signals in arid environments caused by subsurface scattering

open access: yesRemote Sensing of Environment, 2022
Backscatter measured by scatterometers and Synthetic Aperture Radars is sensitive to the dielectric properties of the soil and normally increases with increasing soil moisture content.

Reproducibility in Subsurface Geoscience

open access: yesEarth Science, Systems and Society, 2021
Reproducibility, the extent to which consistent results are obtained when an experiment or study is repeated, sits at the foundation of science. The aim of this process is to produce robust findings and knowledge, with reproducibility being the screening tool to benchmark how well we are implementing the scientific method.

Visualizing Microorganism-Mineral Interaction in the Iberian Pyrite Belt Subsurface: The Acidovorax Case

open access: yesFrontiers in Microbiology, 2020
Despite being considered an extreme environment, several studies have shown that life in the deep subsurface is abundant and diverse. Microorganisms inhabiting these systems live within the rock pores and, therefore, the geochemical and geohydrological ...

Parapatric speciation of Meiothermus in serpentinite-hosted aquifers in Oman

open access: yesFrontiers in Microbiology, 2023
The factors that control the distribution and evolution of microbial life in subsurface environments remain enigmatic due to challenges associated with sampling fluids from discrete depth intervals via boreholes while avoiding mixing of fluids.
