And yet too many American's are missing out on what Bach calls the greatest investment opportunity of our lifetime. The time to change this is now. Today's game changing times demand a game changing plan--and The Automatic Millionaire continues to offer that plan for millions of Americans\"-- Provided by publisher.

Effect of Race on Echocardiographic Measures of Cardiac Structure and Function
The relations between race and cardiac structure and function are incompletely understood. We hypothesized that race-specific differences in echocardiography measurements exist. We compared the relation between echocardiography measurements and race among 12,429 nonobese adults without known cardiovascular disease who underwent echocardiography. We compared measurements between whites (n = 10,508), blacks (n = 792), Asians (n = 628), Hispanics (n = 315), Native Americans (n = 34), and multiracial/other (n = 152) cohorts. Multivariate analysis compared measurements indexed to body surface area (BSA) between races and adjusted for variables including age, gender, and mean blood pressure. Mean age was 46.9 ± 17.4 years and 60.5% were women. After multivariable adjustment and using whites as a baseline, there were significant differences (p <0.05) in left ventricular end-diastolic diameter/BSA for blacks (−0.5 mm/m2), Asians (0.4 mm/m2), Hispanics (0.2 mm/m2), and multiracial/others (0.1 mm/m2); septal wall thickness/BSA for blacks (0.4 mm/m2) and Asians (0.1 mm/m2); posterior wall thickness/BSA for blacks (0.4 mm/m2), Asians (0.1 mm/m2), Hispanics (0.04 mm/m2), and multiracial/others (0.03 mm/m2); left atrial diameter/BSA for Asians (0.2 mm/m2), Hispanics (0.3 mm/m2), and multiracial/others (0.1 mm/m2); septal and lateral e’ for blacks (−0.7 cm/s; −0.9 cm/s); and peak tricuspid regurgitation gradient for blacks (4.3 mm Hg) and Asians (−0.9 mm Hg). Race is associated with significant differences in left ventricular size, left atrial size, mitral annular velocity, and tricuspid regurgitation gradient. Normal reference ranges for echocardiography measurements should utilize racially diverse cohorts to prevent misclassification of echocardiography findings based on race.

Differences in Echocardiographic Measures of Aortic Dimensions by Race
It is not clear whether there are differences in aortic dimensions by race. Our hypothesis was that race-specific differences in aortic size exist. We compared the relation between race and aortic dimensions among 15,295 adults without known risk factors for cardiovascular disease or aortic dilatation, who underwent clinically indicated transthoracic echocardiography. We compared inner edge-to-inner edge measurements between whites (n = 12,932), blacks (n = 958), Asians (n = 827), Hispanics (n = 366), Native Americans (n = 38), and others (n = 174). Multivariate analysis compared measurements indexed with body surface area (BSA) between races and adjusted for variables including age, gender, and mean blood pressure. Mean age was 49.9 ± 17.6 years, and 58.7% were female. On gender-specific comparisons, there were significant differences in aortic size between races (p <0.001 for each). Using whites as a baseline, multivariable analysis demonstrated that blacks had smaller BSA-indexed aortic sinus (−0.34 mm/m2, p <0.001) and ascending aorta (−0.43 mm/m2, p <0.001) dimensions; Asians had larger BSA-indexed aortic sinus (0.36 mm/m2, p <0.001), ascending aorta (0.41 mm/m2, p <0.001), and aortic arch (0.20 mm/m2, p = 0.002) dimensions; Hispanics had larger BSA-indexed aortic arch dimensions (0.15 mm/m2, p = 0.01); Native Americans had increased BSA-indexed aortic arch dimensions (0.32 mm/m2, p = 0.01); and other races had increased BSA-indexed aortic arch dimensions (0.11 mm/m2, p = 0.03). In a cohort without known risk factors for aortic dilatation, race is associated with significant differences in aortic dimensions. In conclusion, these findings suggest that reference ranges for aortic size should be established using racially diverse cohorts to prevent misdiagnosis of aortic dilatation based on race.

Modeling of an Elastocaloric Cooling System for Determining Efficiency
When it comes to covering the growing demand for cooling power worldwide, elastocalorics offer an environmentally friendly alternative to compressor-based cooling technology. The absence of harmful and flammable coolants makes elastocalorics suitable for energy applications such as battery cooling. Initial prototypes of elastocaloric systems, which transport heat by means of thermal conduction or convection, have already been developed. A particularly promising solution is the active elastocaloric heat pipe (AEH), which works with latent heat transfer by the evaporation and condensation of a fluid. This enables a fast and efficient heat transfer in a compression-based elastocaloric cooling system. In this publication, we present a simulation model of the AEH based on MATLAB-Simulink. The model showed very good agreement with the experimental data pertaining to the maximum temperature span and maximum cooling power. Hereby, non-measurable variables such as efficiency and heat fluxes in the cooling system are accessible, which allows the analysis of individual losses including the dissipation effects of the material, non-ideal isolation, losses in heat transfer from the elastocaloric material to the fluid, and other parasitic heat flux losses. In total, it can be shown that using this AEH-approach, an optimized system can achieve up to 67% of the material efficiency.

Phenomenological Material Model for First-Order Electrocaloric Material
Caloric cooling systems are potentially more efficient than systems based on vapour compression. Electrocaloric cooling systems use a phase transformation from the paraelectric to the ferroelectric state by applying or removing an electric field to pump heat. Lead scandium tantalate (PST) materials show a first-order phase transition and are one of the most promising candidates for electrocaloric cooling. To model caloric cooling systems, accurate and thermodynamically consistent material models are required. In this study, we use a phenomenological model based on an analytical equation for the specific heat capacity to describe the material behaviour of bulk PST material. This model is fitted to the experimental data, showing a very good agreement. Based on this model, essential material properties such as the adiabatic temperature change and isothermal entropy change of this material can be calculated.

Usefulness of Echocardiography/Doppler to Reliably Predict Elevated Left Ventricular End-Diastolic Pressure in Patients With Pulmonary Hypertension
The ability of echocardiography (echo)/Doppler to predict elevated left ventricular (LV) end-diastolic pressure (EDP) specifically among patients with pulmonary hypertension is not well defined. This was a retrospective analysis of 161 patients referred to a specialized pulmonary hypertension clinic. A model based on an American Society of Echocardiography (ASE)/European Association of Echocardiography (EAE) joint statement was evaluated, and a new model was developed using univariate linear regression and multivariable logistic regression for potentially better prediction of elevated LVEDP. The study cohort had a median pulmonary arterial pressure was 34.0 mm Hg and pulmonary vascular resistance was 3.7 Wood units; 81 patients (51%) had LVEDP >15 mm Hg on invasive testing. Doppler E/A, E/e′ (septal, lateral, and average), e′/a′ (lateral and average), and left atrial volume and diameter all had significant correlation with LVEDP (p <0.05). The ASE/EAE model performed poorly (sensitivity 54% and specificity 66%) for detecting elevated LVEDP. Only echo/Doppler grade 3 diastolic dysfunction had an LVEDP significantly different from other grades (grade 0 to 2, median 15 mm Hg, interquartile range 13 to 22 mm Hg; grade 3, median 22 mm Hg, interquartile range 19 to 32 mm Hg; p <0.01). An experimental model was statistically significant in its prediction of elevated LVEDP (area under the receiver operating characteristic curve 0.7, p <0.001) but demonstrated poor performance (sensitivity 67% and specificity 61%). In conclusion, numerous echo/Doppler measurements correlate with elevated LV filling pressure. However, both the ASE/EAE model and our experimental model had poor test performance that did not permit confident identification of elevated LVEDP.
