STUDY OBJECTIVE To determine the most appropriate surrogate indicator and its cut off point for identifying low birthweight babies in northern India. STUDY SETTING A secondary level hospital at Ballabgarh. The patients were from nearby rural and urban areas and mostly belonged to lower and middle socioeconomic strata. PARTICIPANTS These comprised 733 singleton newborns delivered in the hosp...

We study the far-field spatial distribution of the quantum fluctuations in the transverse profile of the output light beam generated by a type-II optical parametric oscillator below threshold, including the effects of transverse walk-off. We study how quadrature field correlations depend on the polarization. We find spatial Einstein-Podolsky-Rosen entanglement in quadrature-polarization compone...

OBJECTIVE The aim of this study was to investigate the correlation between the demineralization depth measured by dental computed tomography (CT) and the measured value from a non-destructive dental caries diagnosis with a laser. METHODS Optimal cut-off points were obtained for enamel and dentin caries, from the measured levels from a dental caries diagnosis with a laser, to investigate the c...

The timing of repair and the utility of spectral-domain optical coherence tomography (SD-OCT) for macula-off retinal detachment remains a controversial issue. Four patients who presented with macula-off retinal detachment underwent repair at various time points after symptom onset. Postoperative SD-OCT of the macula demonstrated correlation with final visual acuity.

Undernutrition and hunger have always formed the foundation of the Food and Agriculture Organisation’s (FAO) mandate. Working in collaboration with the International Dietary Energy Consultative Group (IDECG), FAO began to examine both appropriate cut-off points of the body mass index (BMI) at the lower end of the spectrum and the functional consequences of low BMI (<16.0 = Category III Chronic ...
