The double bubble sign in neonates is seen on plain abdominal radiographs in a variety of conditions. It represents gas distended dilated stomach and proximal duodenum, and implies congenital proximal bowel obstruction. A newborn with a double bubble and no distal bowel gas can be presumed to have duodenal atresia and in most cases no further imaging is required. If double bubble is present wit...

--Traffic sign recognition usually consists of two parts : detection and classification. In this paper we describe the classification stage using ring partitioned method. In this method, first the RGB image is converted into gray scale image using color thresholding and histogram specification technique. This gray scale image, called as specified gray scale image is invariant to the illuminatio...

A 52-year-old woman with hypertension presented with a sudden, painless and profound loss of vision in the left eye while doing farm work. Visual acuity was 0.08 only in the affected eye. Ophthalmoscopic examination revealed a large dome-shaped subinternal limiting membrane (sub-ILM) haemorrhage and a subhyaloid haemorrhage located anterior to the sub-ILM haemorrhage. The latter also showed a n...

The sign of the 1~ Cotton effects (CEs) at about 250-27D nm of the benzene chromophore of unsubstituted chiral phenylcarbinamines and their salts is determined by vibronic borrowing from the lBb-allowed transition at shorter wavelength. For these chiral phenylcarbinamines and their salts of the same generic absolute configuration, the sign of their lLb CEs is the same. On ring substitution, how...

BACKGROUND Transverse sinus stenosis (TSS) is common among patients with cerebral venous sinus thrombosis. No previous studies have reported on double-track sign detected on axial Gd-enhanced T1WI in TSS. This study aimed to determine the sensitivity and specificity of the double-track sign in the detection of TSS. METHODS We retrospectively reviewed medical records of 383 patients with trans...

PURPOSE To characterize microaneurysms in diabetic retinopathy (DR) depicted by spectral-domain optical coherence tomography (SD-OCT). DESIGN Retrospective, observational case series. METHODS We surveyed a consecutive series of 76 eyes from 60 patients with DR (22 mild nonproliferative diabetic retinopathy [NPDR]; 43 moderate NPDR; 9 severe NPDR; 2 proliferative diabetic retinopathy [PDR]) ...

Coronary computed tomography angiography (CCTA) is used extensively nowa‐ days as a non-invasive imaging method for the evaluation of patients suspected of coronary artery disease, providing data on calcium burden, the presence of coro‐ nary artery stenoses, but also, more recently, on coronary atherosclerotic plaque morphology and composition. Plaque morphology analysis by CCTA aims to accu‐ r...

The backreaction on black holes due to dragging heavy, rather than test, objects is discussed. As a case study, a regular black Saturn system where the central black hole has vanishing intrinsic angular momentum, J = 0, is considered. It is shown that there is a correlation between the sign of two response functions. One is interpreted as a moment of inertia of the black ring in the black Satur...
