We have generated a high resolution coral A14C record spanning the last 50 years to document the seasonal and interannual redistribution of surface waters in the western tropical Pacific. Prebomb (1947-1956) A14C values average -63%0 and have a total range of 30%0. Values begin to increase in 1957, reaching a maximum of 137%o in mid-1983. Large interannual variability of up to 80%0 closely foll...
It is widely thought that resting state functional connectivity likely reflects functional interaction among brain areas and that different functional areas interact with different sets of brain areas. A method for mapping areal boundaries has been formulated based on the large-scale spatial characteristics of regional interaction revealed by resting state functional connectivity. In the presen...
During the period 2018–2020, Europe experienced a series of hot and dry weather conditions with significant socioeconomic environmental consequences. Yet, extremity these multi-year is not recognized. Here, we provide comprehensive spatio-temporal assessment drought hazard over by benchmarking past exceptional events during from 1766 to 2020. We identified 2018–2020 event as new benchmark havin...
Rates of hypolimnetic oxygen depletion can be predictedfrom a knowledge of a lake's phosphorus retention, the average hypolimnetic temperature, and the mean thickness of the hypolimnion. Areal oxygen deficits cannot be used to index lake trophic status because areal calculations do not eliminate the influence of hypo-limnetic morphometry.
The National Ignition Facility has been used to compress deuterium-tritium to an average areal density of ~1.0±0.1 g cm(-2), which is 67% of the ignition requirement. These conditions were obtained using 192 laser beams with total energy of 1-1.6 MJ and peak power up to 420 TW to create a hohlraum drive with a shaped power profile, peaking at a soft x-ray radiation temperature of 275-300 eV. Th...
Areal interpolation is the process of transferring data collected over source zones to target zones. One of the applications of areal interpolation is to construct temporally consistent areal units for comparing socioeconomic data over time. Dasymetric modeling is the process of employing ancillary data to spatially refine the distribution of socioeconomic variables. In this paper, three areal ...
Predictive analytics beyond time series: Predicting series of events extracted from time series data
Realizing carbon neutral energy generation creates the challenge of accurately predicting time-series data for long-term capacity planning and short-term operational decisions. The key challenges adopting data-driven decision-making, specifically predictive analytics, can be attributed to volume velocity. Data poses storage retrieval. velocity processing near real time decisions or building. Th...
The spatial prediction of point values from areal data of the same attribute is addressed within the general geostatistical framework of change of support; the term support refers to the domain informed by each datum or unknown value. It is demonstrated that the proposed geostatistical framework can explicitly and consistently account for the support differences between the available areal data...
