BACKGROUND Routine health data can guide health systems improvements, but poor quality of these data hinders use. To address concerns about data quality in Malawi, the Ministry of Health and National Statistical Office conducted a data quality assessment (DQA) in July 2016 to identify systems-level factors that could be improved.

The ovine class II major histocompatibility complex mediates specific immune responses to exogenous antigens in sheep. A number of ovine class II loci have been identified, and most of them appear to be polymorphic. In this study we investigated the DQA1 locus of 520 sheep and the DQA2 locus of over 40,000 sheep, finding 12 sequences and 22 sequences, respectively, using DQA1- and DQA2-specific...

The purpose of this study was to present a Monte Carlo (MC) simulation method based on a virtual source, jaw, and MLC model to calculate dose in patient for helical tomotherapy without the need of calculating phase-space files (PSFs). Current studies on the tomotherapy MC simulation adopt a full MC model, which includes extensive modeling of radiation source, primary and secondary jaws, and mul...
