Synthetic Aperture Radar Coherent Change Detection (SAR CCD) images are highly sensitive change maps produced by multiple SAR images. The noise and characteristics of SAR and CCD result in SAR CCD images being challenging to interpret, making human analyst training essential. Simulating a SAR and CCD dataset with realistic noise is an unsolved problem, and collecting real data with a wide varie...

Congenital cardiac disease (CCD) is one of the most common developmental anomalies in children. Affected children require special care in dentistry because of their susceptibility to infective endocarditis from oral infections, yet little information is available on the oral health of children with CCD. The present study, which investigated 39 children with CCD and 33 healthy control siblings, ...

The structure and catalytic properties of the enzyme (E) chlorocatechol dioxygenase (CCD) adsorbed on a citrate-reduced silver colloid are analyzed by surface-enhanced resonance Raman spectroscopy (SERRS). This is the first SERRS study of a non-heme metalloenzyme. It is demonstrated that the native conformation of CCD is retained in the adsorbed state by comparison of resonance Raman scattering...

Conclusion IgE anti-CCD should not be able to connect mast cells and basophils and release inflammatory mediators. Patients with IgE restricted to CCD have not clinical symptoms. CCD can be considered as a potential interference in atopic diagnosis; especially in polisensitized. It ‘s important to provide clinical information to laboratory test. IgE -anti CCD create a misdiagnosis of allergies ...

Little documentation of the correlation between MR imaging findings in isolated cerebellar cortical dysplasia (CCD) and its neuropathologic characteristics exists in the recent literature. We documented a postmortem neuropathologic study of a clinically and radiologically well-documented case of CCD in a neonate with severe hypotonia and status epilepticus. MR imaging revealed a global vermian ...

This report to outlines the work done by the Eta Carinae HST Treasury Project to determine the properties of the cross-dispersion point spread function for the HST Space Telescope Imaging Spectrograph (STIS) CCD. In this document we will refer to the cross-dispersion point spread function by the abbreviation: XSF. The goal of this work is to give a model for the STIS/CCD XSF which can be calcul...

Objectives: Several methods of image acquisition are accessible in dentistry. There is no overall acceptable method for image digitization so all different types of images can be comparable. The objective of this study was to compare the diagnostic accuracy of different methods of image digitization. Methods: This accuracy diagnostic test study used perceptibility curve test which first intr...
