simulation of the solar wind dynamic Pressure Increase in 2014 and its effect on energetic neutral atom fluxes from the heliosphere
The Astrophysical Journal, 2018Co-Authors: E J Zirnstein, J Heerikhuisen, D J Mccomas, N V Pogorelov, D B Reisenfeld, J R SzalayAbstract:In late 2014, the solar wind dynamic Pressure Increased by ~50% over a relatively short time (~6 months). In early 2017, the Interstellar Boundary Explorer (IBEX) observed an Increase in heliospheric energetic neutral atom (ENA) fluxes from directions near the front of the heliosphere. These enhanced ENA emissions resulted from the Increase in SW Pressure propagating through the inner heliosheath (IHS), affecting the IHS plasma Pressure and emission of ~keV ENA fluxes. We expand on the analysis by McComas et al. on the effects of this Pressure change on ENA fluxes observed at 1 au using a three-dimensional, time-dependent simulation of the heliosphere. The Pressure front has likely already crossed the termination shock (TS) in all directions, but ENA fluxes observed at 1 au will change over the coming years, as the TS, heliopause, and IHS plasma Pressure continue to change in response to the SW Pressure Increase. Taken in isolation, the Pressure front creates a "ring" of increasing ENA fluxes projected in the sky that expands in angular radius over time, as a function of the distances to the heliosphere boundaries and the ENA propagation speed. By tracking the position of this ring over time in our simulation, we demonstrate a method for estimating the distances to the TS, heliopause, and ENA source region that can be applied to IBEX data. This will require IBEX observations at 4.3 keV up through ~2020, and longer times at lower ENA energies, in order to observe significant changes from the heliotail.

High-stakes testing and student achievement: Does accountability Pressure Increase student learning?
Education Policy Analysis Archives, 2006Co-Authors: Sharon L. Nichols, Gene V. Glass, David C. BerlinerAbstract:This study examined the relationship between high-stakes testing Pressure and student achievement across 25 states. Standardized portfolios were created for each study state. Each portfolio contained a range of documents that told the “story” of accountability implementation and impact in that state. Using the “law of comparative judgments,” over 300 graduate-level education students reviewed one pair of portfolios and made independent evaluations as to which of the two states’ portfolios reflected a greater degree of accountability Pressure. Participants’ judgments yielded a matrix that was converted into a single rating system that arranged all 25 states on a continuum of accountability “Pressure” from high to low. Using this accountability Pressure rating we conducted a series of regression and correlation analyses. We found no relationship between earlier Pressure and later cohort achievement for math at the fourth- and eighth-grade levels on the National Assessment of Educational Progress tests. Further, no relationship was

Effect of atrial Pressure Increase on sinus node automaticity.
Heart and vessels, 2004Co-Authors: Michael Efremidis, Antonios Sideris, Gerasimos Filippatos, Dimitrios Manolatos, Sotiris Xydonas, Dimitrios Ikonomou, Dimitrios Evangelou, Ilias Sioras, Michael Argyriou, Fotis KardarasAbstract:There is evidence suggesting that atrial electrophysiological properties may be changed by an acute Increase in atrial Pressure. The aim of the present study was to investigate the effect of alteration, in atrial Pressure on sinus node recovery time. Twelve patients (8 men and 4 women, mean age 61.3 ± 14.1 years) were included in this study. None of the patients had organic heart disease. Sinus node recovery time (SNRT) was measured following atrial pacing and atrioventricular (AV) pacing at sequential cycle lengths of 600, 545, 500, 461, 428, and 400 ms with two different AV intervals (150, 0 ms). Peak and minimal atrial Pressure Increased significantly from 8.5 ± 2.8 to 20.1 ± 2.9 mmHg (11.56 ± 3.8 to 27.3 ± 3.9 cmH2O) (P = 0.001) and from 2.06 ± 1.69 to 5.33 ± 2.9 mmHg (2.8 ± 2.29 to 7.2 ± 3.9 cmH2O), respectively (P = 0.002) during AV interval modification. Sinus node recovery time did not change despite the Increase in atrial Pressure. Autonomic blockade had no effect on SNRT. This study demonstrates that atrial Pressure Increase does not significantly affect sinus node automaticity expressed by SNRT.
