Native Americans are characterized by specific and unique patterns of genetic and cultural/linguistic diversities, and this information has been used to understand patterns of geographic dispersion, and the relationship between these peoples. Particularly
Attack graphs compute potential attack paths from a system configuration and known vulnerabilities of a system. Evidence graphs model intrusion evidence and dependencies among them for forensic analysis. In this paper, we show how to map evidence graphs to
One can take advantage of the striking similarity of ignitable liquid vaporization (or weathering) patterns and the separation observed during distillation to predict the composition of residual compounds in fire debris. This is done with the advanced
Attack graphs are used to compute potential attack paths from a system configuration and known vulnerabilities of a system. Attack graphs can be used to eliminate known vulnerability sequences that can be eliminated to make attacks difficult and help

This specification defines Extended Feature Set (EFS) Profiles - sets of features to be used in latent friction ridge (fingerprint, palmprint or plantar) searches of automated friction ridge identification systems (AFIS). The EFS Profiles are designed to
A number of organizations exist around the world that work on a national or international level to aid quality assurance and to promote accurate forensic DNA testing. These organizations are made up primarily of working scientists who coordinate their

The SE33 locus is one of the most polymorphic markers used in human identification. However, it also possesses multiple microvariants both within the repeat and in the flanking regions. Such flanking region mutations can generate discordant allele calls

Precision micro-dispensing is a growing technique that has many applications in the scientific and additive manufacturing communities. Piezoelectric inkjet printing is capable of accurately dispensing exceedingly small volumes of low-viscosity solutions
This study provides an evaluation of DNA extraction methods when tasked with identifying unknown microorganisms. Research, public health, and clinical laboratories frequently turn to DNA-based molecular methods to identify and quantify unknown

Ten (10) pistol slides with consecutively manufactured breech faces, were obtained from Sturm, Ruger Co, Inc. A total of nine (9) test fires from each pistol, for a total of ninety (90) test fired cartridge cases, were compared using comparison microscopy
This article describes the ANSI/NIST-ITL standard: its origin, contents, and how it is used and updated. It is the principal standard used for the formatting and encoding of biometric data and related textual information for law enforcement, homeland
Matcher fusion is a recognized approach for improving biometric system performance. Our interest in fusion was largely to determine how much performance "headroom" exists with current matcher technology. We employed five latent fingerprint matchers, having

Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for more than 100 years. The examination of fingerprints left at crime scenes, generally referred to as latent prints, consists of a
Short tandem repeats (STRs) are accordion-like regions of the human genome that vary in length (through expansion or contraction) with a core repeated DNA sequence. Forensic laboratories commonly use tetranucleotide repeats, containing a four base pair
