Compressive algorithms for search and storage in biological data
… present work on filtering empirical base-calling quality scores from Next Generation Sequencing data. By using the sparsity of k-mers of sufficient length in the human genome and imposing a human prior through the use of frequent k-mers in a large corpus of human DNA reads, we are able to quickly …

Empirical accuracy bounds for next-generation sequencing variant calling workflows
… as a function of read lengths, error rates, quality scores, error types, and mutation types. We utilize these results to quantify the performance gains that can be expected by altering these properties of an NGS dataset. Our results highlight the sensitivity of alignment software to read …

Assessing Early Stage Design Sketches and Reflections on Prototyping
… First, it proposes a rubric for assessing the quality of early stage design sketches including line smoothness, proportion, and understandability. Of particular note is the contribution of assessing understandability as a metric for sketches as communication tools. This study also presents a …

Design and characterization of novel immunogens for AIDS vaccine development and evaluation of a sample inference method for NGS Illumina amplicon data
… have been developed, but most ignore the quality scores or compress that data. We developed ampliclust, an error modeling approach using uncompressed sequences and quality scores to infer samples in Illumina amplicon data. Our approach showed better accuracy than the popular denoising tool …

Software systems for a DNA sequencer
… is a software filter that allows us to generate quality scores from data processed by Trout using Phred. I present the algorithm used to perform the filtering and show that the results are comparable to the processing of data with the Plan- Phred processing package.

Scalable methods for storage, processing and analysis of sequencing datasets
… we describe a lossy compression method for quality scores within sequencing datasets that strikingly improves the downstream accuracy for genotyping. Third, we introduce a Bayesian framework for accurate diploid and polyploid haplotype reconstruction of an individual genome using NGS …

The effects of writing ability and mode of discourse on cognitive capacity engagement
… engaged when writing narrative essays. Analytic quality scores and engagement were related and results were interpreted in the context of schema theory to estimate the learning potential of a given mode of discourse. Also, engagement and syntactic complexity treasures were related. It was found …
