Taxicab Spherical Inversions In Taxicab Space [PDF]

open access: yesJournal of Mahani Mathematical Research, 2020
In this paper, we define an inversion with respect to a taxicab sphere in the three dimensional taxicab space, and prove several properties of this inversion.

Reviews and syntheses: Flying the satellite into your model: on the role of observation operators in constraining models of the Earth system and the carbon cycle [PDF]

open access: yesBiogeosciences, 2017
The vehicles that fly the satellite into a model of the Earth system are observation operators. They provide the link between the quantities simulated by the model and the quantities observed from space, either directly (spectral radiance) or indirectly ...

Assessing the Impact of Atmospheric CO2 and NO2 Measurements From Space on Estimating City-Scale Fossil Fuel CO2 Emissions in a Data Assimilation System

open access: yesFrontiers in Remote Sensing, 2022
The European Copernicus programme plans to install a constellation of multiple polar orbiting satellites (Copernicus Anthropogenic CO2 Monitoring Mission, CO2M mission) for observing atmospheric CO2 content with the aim to estimate fossil fuel CO2 ...

Arctic Mission Benefit Analysis: impact of sea ice thickness, freeboard, and snow depth products on sea ice forecast performance [PDF]

open access: yesThe Cryosphere, 2018
Assimilation of remote-sensing products of sea ice thickness (SIT) into sea ice–ocean models has been shown to improve the quality of sea ice forecasts.

Laurent inversion [PDF]

open access: yesPure and Applied Mathematics Quarterly, 2019
29 pages, 16 figures. This supersedes our earlier preprint with the same name (arXiv:1505.01855 [math.AG]). The new version is much more systematic, and works beyond the toric complete intersection case; it also draws connections to the work of Doran--Harder on amenable collections and Batyrev--Borisov on nef ...

Simultaneous Assimilation of Remotely Sensed Soil Moisture and FAPAR for Improving Terrestrial Carbon Fluxes at Multiple Sites Using CCDAS

open access: yesRemote Sensing, 2018
The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of ...

Mechanics of the Kalabagh Fault, northwest Himalayan fold and thrust belt (convergence zone of India and Eurasia), using SAR interferometry and CFS

open access: yesFrontiers in Earth Science, 2023
The Kalabagh strike–slip fault, which is characterized by right-lateral movement, is part of the northwestern Himalayan foreland fold and thrust belt in Pakistan.

Constraining a land-surface model with multiple observations by application of the MPI-Carbon Cycle Data Assimilation System V1.0 [PDF]

open access: yesGeoscientific Model Development, 2016
We describe the Max Planck Institute Carbon Cycle Data Assimilation System (MPI-CCDAS) built around the tangent-linear version of the JSBACH land-surface scheme, which is part of the MPI-Earth System Model v1.

Implant Straggle Impact on 1.2 kV SiC Power MOSFET Static and Dynamic Parameters

open access: yesIEEE Journal of the Electron Devices Society, 2022
Significant impact of the ion-implant straggle of the P+ shielding region on the static and dynamic characteristics of 1.2 kV 4H-SiC power MOSFETs is demonstrated in this paper by using analytical and TCAD modeling.

Application of Resistivity Method for Mining Tailings Site Selection in Karst Regions [PDF]

open access: yesE3S Web of Conferences, 2020
Disposal of mining wastes (tailings) is one of the most severe issues related to groundwater contamination. Therefore, a properly selected disposal site helps to prevent the leakage of dissolved materials in the tailings to groundwater, especially in the
