Epstein-Barr virus (EBV), a human herpesvirus, affects up to 95% of adults. Diagnosis of acute EBV infection can be challenging and often relies on the serologic antibody pattern to 3 distinct antigens, most often determined by indirect fluorescent antibody (IFA), enzyme-linked immunosorbent assays (ELISAs), and, more recently, multiplex assays. We compared a multiplex assay for the simultaneou...

CONTEXT Almost 70% of young children in India are anemic. Current policy recommends routine iron-folic acid (IFA) supplementation to all under 5 children. A potential risk of this approach is an increase in infectious diseases in general, and malaria in particular. EVIDENCE ACQUISITION An extensive literature search including PubMed, the World Health Organization (WHO) document library, and t...

BACKGROUND The study objective was to understand community preparedness for iron and folic acid (IFA) supplementation early in pregnancy and to inform the design of a large-scale trial of early introduction of IFA supplementation in rural Bangladesh. METHODS 66 in-depth interviews (pregnant women, husbands, and older women in the household), 20 key-informant interviews, 3 focus-group discussi...

background: nowadays, analyzing human facial image has gained ever-increasing importance due to its various applications. image segmentation is required as a very important and fundamental operation for significant analysis and interpretation of images. methods: among the segmentation methods, image thresholding technique is one of the most well-known methods due to its simplicity, robustness a...

Interaction increases flexibility of segmentation but it leads to undesirable behavior of an algorithm if knowledge being requested is inappropriate. In region growing, this is the case for defining the homogeneity criterion, as its specification depends also on image formation properties that are not known to the user. We developed a region growing algorithm that learns its homogeneity criteri...

In order to develop velocimetry methods for confined geometries, we propose to combine image registration and volumetric reconstruction from a monocular video of the draining of a Hele-Shaw cell filled with water. The cell’s thickness is small compared to the other two dimensions (e.g. 1 400 800 mm). We use a technique known as molecular tagging which consists in marking by photobleaching a pat...

Least Squares (LS) estimation is a classical problem, often arising in practice. When the dimension of the problem is large, the solution may be difficult to obtain, due to complexity reasons. A general way to reduce the complexity is that of breaking the problem in smaller sub-problems. Following this approach, in the paper we introduce an Alternating Least Squares (ALS) algorithm that finds t...

This paper deals with an absolute mobile robot selflocalization algorithm in an artificial indoor environment. Until now, localization methods based on conical omnidirectional vision sensors uniquely used radial segments from vertical environment landmarks projection. The main motivation of this work is to show that primitives other than radial straight lines are usable with a conical vision se...

A number of algorithms have been developed for three-dimensional (3D) deconvolution of fluorescence microscopical images. These algorithms use a mathematical-physics model for the process of image formation and try estimate the specimen function, i.e. the distribution of fluorescent dye in the specimen. To keep the algorithms tractable and computational load practical, the algorithms rely on si...

background: brain tissue segmentation for delineation of 3d anatomical structures from magnetic resonance (mr) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (gm), white matter (wm) and cerebrospinal fluid (csf), but only if the obtained segmentation results are correct. due to image arti...
