BACKGROUND AND PURPOSE Patients with traumatic brain injury (TBI) and low Glasgow coma scale (GCS) scores may have severe injury associated with cellular disruption that can be studied with whole-brain apparent diffusion coefficient (ADC) histograms. We retrospectively studied this hypothesis and correlated ADC with GCS. METHODS Twenty-one patients (37.81 +/- 41.3 years) with TBI were enrolle...

We investigated the efficiency droop and polarization-induced internal electric field of InGaN blue light-emitting diodes (LEDs) grown on silicon(111) and c-plane sapphire substrates. The efficiency droop of the LED sample grown on silicon substrates was considerably lower than that of the identically fabricated LED sample grown on sapphire substrates. Consequently, the LED on silicon showed hi...

BACKGROUND The aim of this study was to investigate the role of diffusion-weighted MR imaging (DWI) in the diagnosis of gastric tumors by means of measuring the apparent diffusion coefficient (ADC) values of these lesions, and making a comparison with the endoscopic biopsy results. SUBJECTS AND METHODS Seventy patients having gastric tumor constituted the case group. For the control group 30 ...

Digital competence is one of the significant skills to be possessed by teachers as impact rapid technology development in many aspects such economy, education, health, and environment. Various digital measurements frameworks had been developed ensure that someone has an advance skill those DigComp 2.1 European Commission. Many previous studies studied about teachers’ levels influenced some fact...

OBJECTIVE To examine the effectiveness of apparent diffusion coefficient (ADC) values and to compare the reliability of different b-values in detecting and identifying significant liver fibrosis. SUBJECTS AND METHODS There were 44 patients with chronic viral hepatitis (CVH) in the study group and 30 healthy participants in the control group. Diffusion-weighted magnetic resonance imaging (DWI)...

Lumican is a member of a small leucine-rich proteoglycan family and is highly expressed in several types of cancer cells and/or stromal tissue. Lumican expression in the cytoplasm in advanced colorectal cancer correlates with poor patient prognosis. The expression of lumican in stromal tissues is associated with a high tumor grade, a low estrogen receptor expression level, and young age in brea...

Electric grid is vulnerable to power imbalance and inertia the grid's response overcome such disturbance. Augmentation of electronic converter based renewable energy technologies like Photovoltaic Generators (PVG) batteries in utility significantly reduces inertia. Inertia degradation indicated by sharp Rate Change Frequency (ROCOF) events due any component failure or imbalance. Fixed gain feed...

BACKGROUND Limited data are available regarding the role of magnetic resonance imaging (MRI), particularly the new generation 3 Tesla technology, and especially diffusion-weighted imaging (DWI) in predicting liver fibrosis. The aim of our pilot study was to assess the clinical performance of the apparent diffusion coefficient (ADC) of liver parenchyma for the assessment of liver fibrosis in pat...
