A material that is capable of sustaining a reaction front that moves through the unreacted material at a speed equal to or greater than that of sound in that medium [typically 1000 m/sec (3000 ft/sec)]; a material capable of sustaining a detonation. (See also detonation.)

An impression with observed data that are unambiguous and self-evident due to high clarity and quantity.

In this document, it refers to a MS instrument that can give at least 10,000 nominal mass resolving power at full width of the peak at half its maximum height (FWHM) for the compound of interest.

A rapid pressure rise or high-force explosion characterized by a shattering effect on the confining structure or container and long missile distances.

acquisition of data using a mass spectrometer that can give at least 10,000 nominal mass resolving power at the full width of the peak at half its maximum height (FWHM) for the compound of interest

Cellular level assessment of skeletal, cartilaginous, and dental materials.

A confirmed match that aids an investigation as one or more of the case(s) involved in the match are unsolved.

Sequence(s) returned from GenBank® when performing a BLAST search. Also known as a “subject sequence.”

Homemade Explosives.

The removal of the outer layers of the outsole or tread materials, resulting in openings/gaps with irregular edges.

Death as a result of a volitional act or act of omission (e.g., injury, poisoning, gross neglect of a child) committed by another person to cause fear, harm, pain, or death. Intent to cause death is a common element but is not required for use of the manner of homicide. The classification of homicide for the purposes of death certification is a "neutral" term and neither indicates nor implies criminal intent, which remains a determination within the province of legal processes. 

NOTE There may be cases, such as acts of serious neglect (e.g., firing a bullet into the air) or application of force (e.g., restraint) that, in the opinion of the certifier, warrant the classification of homicide..

A region of DNA made up of a single repeated base.

A segment of DNA consisting of repeats of a single nucleotide; may cause slippage during amplification and sequencing.

The angle in a horizontal plane between the path of a bullet and an object that was struck, measured at the point of impact, also known as azimuth angle.

Autopsy requested by a medical caretaker or healthcare facility, usually authorized by the next of kin.

A base or region of DNA that mutates more frequently than areas around it.

Non-target person placed within a search area.

analysis of specimens for driving while impaired cases, drug-facilitated crimes, and other impairment cases to determine the presence (or absence) of chemical substances and their effects on the average individual

The way in which human scent moves or reacts in a given environment. Factors that influence the dispersion of scent may include wind, temperature, air currents, and topography. An example would be a plume of scent that a canine has been trained to follow to its target.

A particular person's scent collected for use for investigative purposes.

A canine trained to locate and indicate items in question by means of detecting human scent.

Individual that laid a track/trail for a canine to follow to the exclusion of all other trails

recruitment, transportation, transfer, harboring, or receipt of persons by improper means (such as force, abduction, fraud, or coercion) for an improper purpose including forced labor or sexual exploitation). 

Search determinedly for someone or something

The science of providing for the needs of an animal including housing, daily care, feeding, exercise, and meeting the behavioral/mental/emotional needs of the animal.

An explosible heterogeneous mixture, comprising gas with suspended solid or liquid particulates, in which the total flammable gas concentration is 10 percent of the lower flammable limit (LFL) and the total suspended particulate concentration is 10 percent of the minimum explosible concentration (MEC). [68, 2018]

Interbreeding between two taxa that are considered to have diverged in their genetic makeup and taxonomic relationship (e.g., between members of different families, genera, or species). Hybridization commonly occurs between subspecies or closely related species.

Any substance that will spontaneously ignite or explode upon exposure to an oxidizer.

A segment of DNA that often contains polymorphisms and thus is useful for differentiating taxa or unrelated individuals.

A section of the human mtDNA control region spanning nucleotide positions 16024-16365, that often differs among non-maternally related individuals.

A section of the human mtDNA control region spanning nucleotide positions 16024-16365, that often differs among non-maternally related individuals.

A section of the human mtDNA control region spanning nucleotide positions 73-340, that often differs among non-maternally related individuals.

A section of the human mtDNA control region spanning nucleotide positions 73-340, that often differs among non-maternally related individuals.

Abbreviation for Hertz, which is the measure of the frequency of oscillations. It is thefundamental property of sound that determines pitch.

Hertz is the international unit of measurement of frequency. One hertz corresponds to one cycle per second.

Acronym for the Integrated Automated Fingerprint Identification System of the FBI.

Acronym for Iris Acquisition Profile. It is a series of sets of progressively morestringent parameters and requirements relevant to iris acquisition. [2015a>] In theMobile ID Best Practices Recommendations Version 1, face, finger and iris applicationprofiles were all referred to as SAP. They are referred to separately in this standard.This was changed in Mobile ID Best Practices Recommendations Version 2 to beconsistent with this standard.
