ooking back, the signs were there for several years. Grandma Blanche started misplacing her keys and wallet in her early 50s. Having lived through the Great Depression, my grandma would hide money around the house rather than have it all deposited in a bank. The problem was she would forget where she hid it. I can remember my mother going through every inch of Grandma’s house one day and collec...

The language Grace is being proposed for specifying and programming in a graph-centered environment based on graph transformation. Emphasis in the design of Grace is laid on modular structur-ing of programs. In this paper we present a simple kind of modules for the language which encapsulate rules and graph transformation units, and export some of them. The local transformation units deene comp...

the military hopsitals of India. Those whose niemoiies of India carry them hack to the year 1888 will not forget the arrival of the nursing sisters and the difference which they made in the comforts of the station hospitals in India. The little book is edited by Surgeon-General A F. Bradshaw, CB, who will be remembered bv many as P. M. O. in Rawal Pindi, and afterward as P. M. 0., H. M.'s Force...

The vertical motion of the Earth’s surface is dominated by hydrologic cycle on a seasonal scale. Accurate land deformation measurements can provide constructive insight into regional geophysical process. Although Global Positioning System (GPS) delivers relatively accurate measurements, GPS networks are not uniformly distributed across globe, posing challenge to obtaining information in data-sp...

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...
