The Key Informant method (KIM) - a novel means of ascertaining blind children in Bangladesh [PDF]
, 2007 BACKGROUND: Most information on the causes of blindness has come from examining children in special education. To obtain a more representative population-based sample of children, a novel method was developed for ascertaining severe visually impaired ...

Blind Channel Estimation Using Redundant Precoding: New Algorithms, Analysis, and Theory [PDF]
, 2008 Digital signal processing (DSP) techniques have played an important role in channel equalization and estimation in communication systems. While channel equalization and estimation are usually done by pilot-assisted methods in most systems, algorithms for

Blind deconvolution of sparse pulse sequences under a minimum distance constraint: a partially collapsed Gibbs sampler method [PDF]
, 2012 For blind deconvolution of an unknown sparse sequence convolved with an unknown pulse, a powerful Bayesian method employs the Gibbs sampler in combination with a Bernoulli–Gaussian prior modeling sparsity.

Effectiveness and Safety of Heparinized Saline versus Normal Saline in Maintaining Patency of Peripheral Intravenous Locks in Neonates at a Tertiary Care Hospital [PDF]
Journal of Clinical and Diagnostic Research, 2017 Introduction: Heparinized saline is usually used as a regular flush solution to prevent occlusion of peripheral intravenous locks in neonates but the risks associated with the use of heparin cannot be ignored in these patients.

Blinded assessment of treatment effects utilizing information about the randomization block length [PDF]
, 2009 It is essential for the integrity of double-blind clinical trials that during the study course the individual treatment allocations of the patients as well as the treatment effect remain unknown to any involved person.
