Figure 3: Myocardial signal (mean ± SEM) as function of echo-time (TE based on effective TE (circles) or preparation time (stars)) for n = 0-6 blocks, τ = 2.3ms (filled) and interleaved series (n = 2 or 4) with adjusted τ (open). The dashed line indicates the fit of the first 3 points of the effective TE data. Figure 2: A) T2-weighted short-axis images with varying echo times (n = 0, 3 and 6). ...

We obtained ZnO Nanowires films deposited on two types of substrate (Si (100) and glass) with 12 wt % PbS as dopant by simple thermal evaporation technique. High Resolution Transmission Electron Microscopy (HRTEM) Energy-dispersive X-ray spectroscopy(EDX) images have confirmed the formation (NWs). EDX technique was used to investigate elements content (standard analysis mapping modes). Morpholo...

S U M M A R Y Mapping the elastic and anelastic structure of the Earth’s mantle is crucial for understanding the temperature, composition and dynamics of our planet. In the past quarter century, global tomography based on ray theory and first-order perturbation methods has imaged longwavelength elastic velocity heterogeneities of the Earth’s mantle. However, the approximate techniques upon whic...

Degassing is a common preparation technique for rhenium filaments used for thermal ionization mass spectrometric analysis of actinides, including plutonium. Although optimization studies regarding degassing conditions have been reported, little work has been done to characterize filament aging after degassing. In this study, the effects of filament aging after degassing were explored to determi...

BACKGROUND Physical inactivity is one of the modifiable risk factors for hippocampal atrophy and Alzheimer's disease. We investigated the relationship between physical activity, hippocampal atrophy, and memory using structural equation modeling (SEM). MATERIALS AND METHODS We examined 213 community-dwelling elderly subjects (99 men and 114 women with a mean age of 68.9 years) without dementia...
