IR Frequency Region: Fingerprint Region01:03

IR Frequency Region: Fingerprint Region

1.5K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

Imprinting01:22

Imprinting

10.4K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Methods of Classification and Identification

660
Bacterial identification relies on a diverse array of techniques to classify and understand microorganisms, each tailored to uncover specific characteristics. Traditional morphological approaches, while still valuable, are limited for closely related or structurally simple organisms. Modern methods integrate biochemical, serological, genetic, and advanced molecular tools to achieve greater accuracy.Morphological and Biochemical TechniquesMorphological characteristics, such as cell shape and...

    Area of Science:

    • Biometrics
    • Public Health
    • Pediatrics

    Background:

    • Infant mortality remains high in developing countries due to vaccine-preventable diseases and malnutrition.
    • Lack of identification hinders tracking of infant vaccinations and nutritional supplement delivery.
    • Accurate infant identification is crucial for timely healthcare interventions.

    Purpose of the Study:

    • To introduce Infant-Prints, a novel, low-cost infant fingerprint recognition system.
    • To evaluate the accuracy and reliability of Infant-Prints for infant identification over time.
    • To enable effective tracking of infant healthcare interventions, including vaccinations and nutritional supplements.

    Main Methods:

    • Development of a custom, compact, low-cost (85 USD), high-resolution (1,900 ppi) infant fingerprint reader.
    • Implementation of a high-resolution infant fingerprint matcher.
    • Collection of a longitudinal infant fingerprint database from 315 infants over 12 months in India.

    Main Results:

    • Demonstrated accurate and reliable recognition of infants over a 12-month period.
    • Achieved a True Acceptance Rate (TAR) of 95.2% at a False Acceptance Rate (FAR) of 1.0% for infants aged 8-16 weeks at enrollment, authenticated 3 months later.
    • Validated the system's efficacy for infants enrolled between 2-3 months of age.

    Conclusions:

    • Infant-Prints provides a viable solution for accurate infant identification in resource-limited settings.
    • The system facilitates timely delivery of critical healthcare and nutritional support to infants.
    • This technology has the potential to significantly reduce infant suffering and mortality globally.
