Eugene Newman Parker, the leading figure in heliospheric physics for past half century, died of complications Parkinson’s disease on 15 March 2022 Chicago. Among other distinctions, he was first individual to be honored by having a NASA mission—the Parker Solar Probe—named after him while still living.Eugene ParkerCOURTESY OF ERIC PARKERPPT|High resolutionParker born 10 June 1927 Houghton, Mich...

This project examines a sequence of Tertiary volcanic rocks from the Langidalsfjall mountain range in the Skagi Peninsula of north-central Iceland, formed at about 7-8 Ma. This sequence is composed of basaltic flows, andesitic flows, and rhyolitic rocks (a flow and a dike). The main unit of interest is a 30-40 m thick plagioclase-phyric andesite flow. This flow contains calciumrich (up to An88)...

Less than 1% of the pre-European settlement forest in Ohio currently remains, mostly as small and scattered woodlots. Consequently, few studies have been undertaken to quantify the composition and structure of Ohio’s old-growth forests using a landscape ecosystem perspective. We used an existing multifactor ecosystem classification system developed for the Wayne National Forest in southeastern ...

We present a prediction methodology for reservoir oil production rates which assesses uncertainty and yields confidence intervals associated with its prediction. The methodology combines new developments in the traditional areas of upscaling and history matching with a new theory for numerical solution errors and with Bayesian inference. We present recent results of coworkers and ourselves. Int...

We consider a sequential approach for the solution of an elliptic-hyperbolic system of partial differential equations, which models a flow of two incompressible phases in porous media. The elliptic equation describes the pressure distribution in the domain, and the hyperbolic equation is the mass conservation equation for one of the phases. We propose to estimate an optimal number of the pressu...

The phenomenological possibilities of the Randall-Sundrum non-compact extra dimension scenario with the AdS horizon increased to approximately a millimeter length, corresponding to an effective brane tension of (TeV)4, are investigated. The corrections to the Newtonian potential are found to be the only observationally accessible probe of this scenario, as previously suggested in the literature...
