BACKGROUND In acute coronary syndrome (ACS), both the Global Registry of Acute Coronary Events (GRACE) score and B-type natriuretic peptide (BNP) predict cardiovascular events. However, it is unknown how BNP compares with GRACE and how their combination performs in ACS. METHODS The authors recruited 449 consecutive ACS patients and measured admission GRACE score and bedside BNP levels. The ma...

Abstract. Total water storage change (TWSC) reflects the balance of all fluxes in a hydrological system. The Gravity Recovery and Climate Experiment/Follow-On (GRACE/GRACE-FO) monthly gravity field models, distributed as spherical harmonic (SH) coefficients, are only means observing this state variable. well-known correlated noise these observations requires filtering, which scatters actual mas...

Fibrinogen (Fib) is considered to be a potential risk factor for the prognosis of patients with acute coronary syndrome (ACS), but it is unclear whether Fib level have synergistic effects to enhance the prognostic value of the GRACE score in patients with ACS. A retrospective analysis was conducted from a single registered database. 2253 consecutive patients with ACS confirmed by coronary angio...

The impact of new geoid height models on estimates of the ocean circulation, now available from the Gravity Recovery and Climate Experiment (GRACE) spacecraft, is assessed, and the implications of far more accurate geoids, anticipated from the European Space Agency’s (ESA) Gravity and Ocean Circulation Explorer (GOCE) mission, are explored. The study is based on several circulation estimates ob...

gravity recovery and climate experiment (grace) satellite gravimetry mission launched in march 2002 based on its twin gravimetric satellites makes application of both high-low (hl) and law-low (ll) gravimetric techniques possible. the ll is based on satellite-to-satellite tracking (sst) via the one way two frequencies k-band-ranging between the two grace satellites. as a result of combination o...

The Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) provided twenty years of data on Earth’s time-varying gravity field. Due to their design, GRACE-FO are inherently limited in spatiotemporal coverage, limiting resolution a few hundred kilometers temporally roughly monthly solutions. To increase the global allow for determination submonthly field signals, constellatio...

In an attempt to solve as much of the AAAI Robot Challenge as possible, five research institutions representing academia, industry and government, integrated their research on a pair of robots named GRACE and GEORGE. This paper describes the second year effort by the GRACE team, the various techniques each participant brought to GRACE, and the integration effort itself.

The Gravity Recovery and Climate Experiment (GRACE) has demonstrated that low–low satellite-tosatellite tracking enables monitoring the time variations of the Earth’s gravity field on a global scale, in particular those caused by mass-transport within the hydrosphere. Due to the importance of long-term continued monitoring of the variations of the Earth’s gravitational field and the limited lif...

Over the past four decades, land use/land cover (LU/LC) change, coupled with persistent drought, has resulted in the decline of groundwater levels in Horqin Sandy Land. Accordingly, this study quantifies changes in LU/LC and groundwater storage (GWS). Furthermore, it investigates the effects of LU/LC changes on GWS. GWS changes are estimated using Gravity Recovery and Climate Experiment (GRACE)...

BACKGROUND In patients with non-ST elevation acute coronary syndrome (NSTE-ACS), identification of the patients with high-risk coronary anatomy (HRCA) who are most likely to require coronary artery bypass grafting (CABG) is crucial. The SYNTAX score (SXscore) is an angiographic grading tool designed to determine the complexity of coronary artery disease. It appears that CABG offers significantl...
