Stress-Induced Leakage current (SILC) on ultra-thin SiO2 was measured in-situ by using a high-resolution measurement technique in a special designed chamber at 100°C with temperature stability of 0.002°C. A gate stress voltage range was measured from –3.1V down to –1.5V in steps of 0.2V. Even at these low voltages, no significant change in the degradation mechanism could be observed. Extrapolat...

This research was performed with the objective of evaluating the accuracy of spectral angle mapper (SAM) classification using different reference spectra. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) digital images were applied in the SAM classification in order to map the distribution of hydrothermally altered rocks in the Kerman Cenozoic magmatic arc (KCMA), Iran...

This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...

BACKGROUND AND OBJECTIVE The management of community-acquired pneumonia (CAP) depends, in part, on the identification of the causative agents. The objective of this study was to determine the potential of thin-section computed tomography (CT) in differentiating bacterial and non-bacterial pneumonia. PATIENTS AND METHODS Thin-section CT studies were prospectively examined in hospitalized CAP p...

Since all the image data need in this research were collected from the highly modified AS&E 101ZZ system, it is important to give an overview to this scanning hardware. Section 3.1 gives a system hardware overview. Section 3.2 discusses issues regarding xray detectors and image preprocessing. Section 3.3 discusses the relationship between the x-ray signal intensity and the image gray level. Sec...

Body image dissatisfaction, which is increasing as an issue for women, can diminish quality of life with negative psychological consequences. The relationship between internalizing the thin body ideal and the development of body image dissatisfaction has been studied in psychology. The thin body ideal is aspiring to a perfect female body that is very thin, presented as the ideal in the media. R...

Editorials on a CT slice. Using 10 mm thick CT slices, the diagnostic yield from fiberoptic bronchoscopic procedures (FOB) was 60 percent for SPNs with the positive bronchus sign, and 30 percent for SPNs without this sign. Some SPNs were also scanned using 1.5 mm thick slices (thin-section CT), and the diagnostic yield of SPN without the positive bronchus sign dropped from 30 to 14 percent. Thi...

OBJECTIVE To investigate the correlation between radiologic vascular dilatation and serum nitrite concentration and eNOS expression in the endothelial cell and pneumocyte in a rabbit model of hepatopulmonary syndrome induced by common bile duct ligation (CBDL). MATERIALS AND METHODS Thin-section CT scans of the lung and pulmonary angiography were obtained 3 weeks after CBDL (n = 6), or a sham...

In this study, acetylcholine receptor-rich postsynaptic membranes from electric tissues of the electric rays Narcine brasiliensis and Torpedo californica are negatively contrasted for thin-section electron microscopy through the use of tannic acid. Both outer (extracellular) and inner (cytoplasmic) membrane surfaces are negatively contrasted, and can be studied together in transverse sections. ...

We compared the thin-section CT findings of 11 intrapulmonary lymph nodes with pathological findings and evaluated the possibility of CT scan differential diagnosis from pulmonary metastatic nodules. First, we retrospectively reviewed CT scan and pathological findings of intrapulmonary lymph nodes. The median size of these nodules was 6.2 mm. The nodules appeared round (n=3) or angular (n=8) in...
