An Investigation of Downstream Processing Methods for Challenging Skeletal Samples

Abstract: While skeletal remains are known for their resilience and often serve as the final source of information for unidentified human remains (UHRs), the traditional downstream processing of these samples is challenging due to their low template nature, DNA degradation, and the presence of PCR inhibitors, typically resulting in limited...

Sample mixtures and the ability to deconvolute SNP profiles present a challenge for investigations using FGG. These mixtures are common in forensics, however, database search algorithms utilized for FGG only accommodate single-source SNP profiles. To address this gap, NBFAC and Signature Science have collaborated to implement a workflow which enables... MORE

PLANES: Plausibility Analysis of Epidemiological Signals

Abstract: Methods for reviewing epidemiological signals are necessary to building and maintaining data-driven public health capabilities. We have developed a novel approach for assessing the plausibility of infectious disease forecasts and surveillance data. The PLANES (PLausibility ANalysis of Epidemiological Signals) methodology is designed to be multi-dimensional and flexible, yielding an overall score based... MORE

MixDeR: A SNP Mixture Deconvolution Workflow for Forensic Genetic Genealogy

Abstract: The generation of forensic DNA profiles consisting of single nucleotide polymorphisms (SNPs) is now being facilitated by wider adoption of next-generation sequencing (NGS) methods in casework laboratories. At the same time, and in part because of this advance, there is an intense focus on the generation of SNP profiles... MORE
