Drought is a complex natural hazard which can have negative effects on agriculture, economy, and human life. In this paper, the primary goal is to explore the application of the Gravity Recovery and Climate Experiment (GRACE) gravity satellite data for the quantitative investigation of the recent drought dynamic over the arid land of northwestern China, a region with scarce hydrological and met...

BACKGROUND Acute coronary syndrome registries report the use of incomplete guideline therapies, especially among the highest risk patients. Whether this treatment gap results from misperceptions of risk by physicians is uncertain. METHODS AND RESULTS The Perceived Risk of Ischemic and Bleeding Events in Acute Coronary Syndrome Patients (PREDICT) study was a prospective acute coronary syndrome...

BACKGROUND In HIV infection, dynamic marginal structural models have estimated the optimal CD4 for treatment initiation to minimize AIDS/death. The impact of CD4 observation frequency and grace periods (permitted delay to initiation) on the optimal regimen has not been investigated nor has the performance of dynamic marginal structural models in moderately sized data sets-two issues that are re...

This work was produced under the auspices of the SERC funded project GR/G49531. Z, Z Method, OBJ, Abstract Datatypes, Safety Critical Systems, Initiality Z is a rich and expressive speci cation language. It is possible to use Z to produce clear, abstract and elegant speci cations; it is also possible to use Z to produce meaningless speci cations. One of the overall aims of the research work in ...

BACKGROUND Although the TIMI score is the one most frequently used in acute coronary syndromes (ACS) without ST-segment elevation, the GRACE score has potential prognostic superiority, as it was created based on an observational registry, part of the variables is treated in a semi-quantitative form and renal function is taken into account in its calculation. OBJECTIVE To test the hypothesis t...

BACKGROUND The GRACE Score was derived and validated from a cohort in which octogenarians and nonagenarians were poorly represented. OBJECTIVE To test the accuracy of the GRACE score in predicting in-hospital mortality of very elderly individuals with acute coronary syndromes (ACS). METHODS Prospective observational study conducted in the intensive coronary care unit of a tertiary center fr...

OBJECTIVES The Global Registry of Acute Coronary Events (GRACE) registry reported that the in-hospital risk of death from non-ST elevation myocardial infarction (NSTEMI) is 5%, with an 11% mortality by 6 months. Prospective Registry of Acute Ischaemic Syndromes in the UK demonstrated that the overall risk of death from NSTEMI over 4 years is 25%. In GRACE, while 28% of patients received percuta...

BACKGROUND Although cardiovascular disease is the major cause of premature death among Indigenous peoples in several advanced economies, no acute coronary syndrome (ACS) risk models have been validated in Indigenous populations. We tested the validity and calibration of three Global Registry of Acute Coronary Events (GRACE) scores among Aboriginal and non-Aboriginal Australians. METHODS GRACE...

Water storage change has implications not only for the hydrological cycle, but also for sustainable water resource management in especially semi-arid river basins. Satellite/remote sensing techniques have gained increasing application in monitoring basin and regional hydrological processes in recent decades. In this study, the latest version of GRACE (Gravity Recovery and Climate Experiment) is...

AIM To compare the prognostic performance of three major risk scoring systems including global registry for acute coronary events (GRACE), thrombolysis in myocardial infarction (TIMI), and prediction of 30-day major adverse cardiovascular events after primary percutaneous coronary intervention (RISK-PCI). METHODS This single-center retrospective study involved 200 patients with acute coronary...
