(Cambridge Univ., 2020)It is well understood that a supercritical superprocess is equal in law to a discrete Markov branching process whose genealogy is dressed in a Poissonian way with immigration which initiates subcritical superprocesses. The ...
-
(Elsevier, 2020)While collecting data for estimating discrete-choice models, researchers often encounter missing information in observations. In addition, endogeneity can occur whenever the error term is not independent of the observed ...

(Cambridge Univ., 2020)Glacier ice thickness is crucial to quantifying water resources in mountain regions, and is an essential input for ice-flow models. Using a surface velocity inversion method, we combine ice thickness measurements with ...
-
(Elsevier, 2020)COVID-19 pandemic has reshaped our world in a timescale much shorter than what we can understand. Particularities of SARS-CoV-2, such as its persistence in surfaces and the lack of a curative treatment or vaccine against ...
-
(Elsevier, 2020)Natural geysers on Earth are uncommon and most of them are clustered in large basins that share common characteristics, specifically, a magmatic heat source, meteoric water supply, and a set of fractures and/or porous rocks ...
-
(Pergamon-Elsevier, 2020)Fracture opening at low differential stress controls maximum sustainable fluid pressure (lambda) within cohesive brittle crust. Standard Andersonian stress states occur when two conditions are met: (1) one of the principal ...
-
(Soc Exploration Geophysicists, 2020)Understanding and monitoring the seismic responses of rock masses to massive mining are crucial for safety and economic viability of ever larger and deeper underground operations. Seismic monitoring can be used to detect ...
