Students struggle to understand many concepts in statistics such as when to use the appropriate inferential statistic to run a statistical analysis. This study was the first of its kind to incorporate interleaved practice, a form of distributed practice, into a Statistics in Psychology course to see if this educational intervention can help students ...

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background In chronic liver disease, fat and fibroinflammatory changes often coexist. However, their biomarkers, proton density fat fraction (PDFF) and T1, are typically assessed separately. Their reproducibility under mutual confounding remains unclear.

Characterization of Pulmonary Functional Abnormalities in Systemic Sclerosis Using Xenon MRI
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Xenon MRI is increasingly used to evaluate patients with interstitial lung disease (ILD) and pulmonary hypertension (PH), both of which are common manifestations of systemic sclerosis (SSc). As such, Xe‐MRI may be suited to interrogate lung function impairment in SSc.

Design and Evaluation of Adaptive (Serial/Parallel) Concatenated Convolutional Codes
Journal of Engineering and Sustainable Development, 2006 In this paper, parallel Concatenated Convolutional Codes (PCCCs) is modeled as a special case of Serial Concatenated Convolutional Code (SCCCs). Consequently, resulting in Adaptive (parallel/serial) concatenated convolutional code in which the same ...

Cerebral Blood Transit in Sickle Cell Anemia
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...
