Continuous observations of temporal variations in the Earth's gravity field have recently become available at an unprecedented resolution of a few hundreds of kilometers. The gravity field is a product of the Earth's mass distribution, and these data-provided by the satellites of the Gravity Recovery And Climate Experiment (GRACE)-can be used to study the exchange of mass both within the Earth ...

mediate-risk scores from the Global Registry of Acute Coronary Events (GRACE) revealed little difference in the primary outcome in terms of the strategies (7.7% early, 6.7% delayed; P = 0.43); however, the difference favoring the early strategy was significant for the group with high GRACE risk scores (14.1% early vs. 21.6% delayed; P = 0.0097). There were no significant differences in major bl...

Since March 2002, the GRACE mission provides monthly global maps of geoid time-variations. These new data carry information on the continental water storage, including snow mass variations, with a ground resolution of ~600-700 km. We have computed monthly snow mass solutions from the inversion of the 22 GRACE geoids (04/2002-05/2004). The inverse approach developed here allows to separate the s...

This paper introduces GRACE – the Global Replication and Consistency Environment – a layered architecture deployed on Distributed Hash Tables (DHT), in which the tension between availability, consistency and performance is mitigated both by providing support for relaxed consistency semantics and by the DHT technology. We describe how the benefits of DHTs, such as scalable lookup and ease of man...

A new methodology is proposed to estimate changes in the Earth's dynamic oblateness ([Formula: see text] or equivalently, [Formula: see text]) on a monthly basis. The algorithm uses monthly Gravity Recovery and Climate Experiment (GRACE) gravity solutions, an ocean bottom pressure model and a glacial isostatic adjustment (GIA) model. The resulting time series agree remarkably well with a soluti...

BACKGROUND Comparisons between dedicated risk scores in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) in real-world clinical practice are scarce. The aim of this study was to assess the diagnostic performance of the Global Registry of Acute Coronary Events (GRACE), Primary Angioplasty in Myocardial Infarction (PAMI)...

BACKGROUND When performing coronary angiography in patients with acute coronary syndrome (ACS), the anatomical extent of coronary disease usually prevails in the prognostic reasoning. It has not yet been proven if clinical data should be accounted for in risk stratification together with anatomical data. OBJECTIVE To test the hypothesis that clinical data increment the prognostic value of ana...

[1] Groundwater is a primary hydrological reservoir of the Great Lakes Water Basin (GLB), which is an important region to both Canada and US in terms of culture, society and economy. Due to insufficient observations, there is a knowledge gap about groundwater storage variation and its interaction with the Great Lakes. The objective of this study is to examine the detectability of the groundwate...
