GEO-BLEU: Similarity Measure for Geospatial Sequences
(ACM|The 30th International Conference on Advances in Geographic Information Systems, 2022-11-01) -
Geo-located Twitter as proxy for global mobility patterns
(Cartography & Geographic Information Society, 2014-02)Pervasive presence of location-sharing services made it possible for researchers to gain an unprecedented access to the direct records of human activity in space and time. This article analyses geo-located Twitter messages ... -
Geobiology of the late Paleoproterozoic Duck Creek Formation, Western Australia
(Elsevier BV, 2010-03)The ca. 1.8 Ga Duck Creek Formation, Western Australia, preserves 1000 m of carbonates and minor iron formation that accumulated along a late Paleoproterozoic ocean margin. Two upward-deepening stratigraphic packages are ... -
Geochemical conditions conducive for retention of trace elements and radionuclides during shale–fluid interactions
(Royal Society of Chemistry (RSC), 2019-09)Produced water generated during unconventional oil and gas extractions contains a complex milieu of natural and anthropogenic potentially toxic chemical constituents including arsenic (As), chromium (Cr), and cadmium (Cd), ... -
Geochemical evaluation of the surface erosion for a hidden Cu-Au porphyry deposit using soil samples along with 3D ore-body modeling
(Springer International Publishing, 2022-06-13)Abstract As the exploration process is time-consuming, costly, and risky, determination of the erosion surface of a metallic deposit before geophysical survey and exploration drilling might be very helpful. ... -
Geochemistry of fluids from Earth’s deepest ridge-crest hot-springs: Piccard hydrothermal field, Mid-Cayman Rise
(Elsevier BV, 2018-02)Hosted in basaltic substrate on the ultra-slow spreading Mid-Cayman Rise, the Piccard hydrothermal field is the deepest currently known seafloor hot-spring (4957–4987 m). Due to its great depth, the Piccard site is an ... -
Geodesically Parameterized Covariance Estimation
(Society for Industrial & Applied Mathematics (SIAM), 2021) -
Geodesics and metric ball boundaries in Liouville quantum gravity
(Springer Berlin Heidelberg, 2022-02-11)Abstract Recent works have shown that there is a canonical way to to assign a metric (distance function) to a Liouville quantum gravity (LQG) surface for any parameter ... -
Geodetic Evidence That Mercury Has A Solid Inner Core
(American Geophysical Union (AGU), 2019-04)Geodetic analysis of radio tracking measurements of the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft while in orbit about Mercury has yielded new estimates for the planet's gravity field, tidal ... -
The Geographic Concentration of Enterprise in Developing Countries
(Oxford University Press, 2011)A nation's economic geography can have an enormous impact on its development. In Thailand, we show that a high concentration of enterprise in an area predicts high subsequent growth in and around that area. We also find ... -
Geographic Constraints on Social Network Groups
(Public Library of Science, 2011-04)Social groups are fundamental building blocks of human societies. While our social interactions have always been constrained by geography, it has been impossible, due to practical difficulties, to evaluate the nature of ... -
Geographic max-flow and min-cut under a circular disk failure model
(Institute of Electrical and Electronics Engineers (IEEE), 2012-03)Failures in fiber-optic networks may be caused by natural disasters, such as floods or earthquakes, as well as other events, such as an Electromagnetic Pulse (EMP) attack. These events occur in specific geographical ... -
Geographic patterns of genomic diversity and structure in the C4 grass Panicum hallii across its natural distribution
(Oxford University Press (OUP), 2021)<jats:title>Abstract</jats:title> <jats:p>Geographic patterns of within-species genomic diversity are shaped by evolutionary processes, life history and historical and contemporary factors. New genomic ... -
A geographically-diverse collection of 418 human gut microbiome pathway genome databases
(Nature Publishing Group, 2017-04)Advances in high-throughput sequencing are reshaping how we perceive microbial communities inhabiting the human body, with implications for therapeutic interventions. Several large-scale datasets derived from hundreds of ... -
Geographies of Cuban Abstraction
(Project Muse, 2019-12) -
The geography of taste: analyzing cell-phone mobility and social events
(Springer-Verlag, 2010-05)This paper deals with the analysis of crowd mobility during special events. We analyze nearly 1 million cell-phone traces and associate their destinations with social events. We show that the origins of people attending ... -
The Geography of Trade and Technology Shocks in the United States
(American Economic Association, 2013-05)This paper explores the geographic overlap of trade and technology shocks across local labor markets in the United States. Regional exposure to technological change, as measured by specialization in routine task-intensive ... -
Geological, multispectral, and meteorological imaging results from the Mars 2020 Perseverance rover in Jezero crater
(American Association for the Advancement of Science (AAAS), 2022-11-25)<jats:p>Perseverance’s Mastcam-Z instrument provides high-resolution stereo and multispectral images with a unique combination of spatial resolution, spatial coverage, and wavelength coverage along the rover’s traverse in ... -
Geomechanical Characterization of Marcellus Shale
(Springer Vienna, 2016-04)Understanding the reservoir conditions and material properties that govern the geomechanical behavior of shale formations under in situ conditions is of vital importance for many geomechanical applications. The development ...
