Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision01:24

Color Vision

1.4K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Changes in Skin Color: Clinical Perspectives

3.4K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Gene Conversion

10.6K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

    Area of Science:

    • Optics and Photonics
    • Computer Graphics
    • Digital Signal Processing

    Background:

    • Generating full-color computer-generated holograms (CGHs) is computationally intensive.
    • Existing methods like look-up tables and fast Fourier transform-based approaches face speed limitations.

    • Developed the WAvelet ShrinkAge-Based superpositIon (WASABI) method.
    • Utilized wavelet transform for light wave superposition, employing 3%, 5%, and 10% of wavelet components.
    • Integrated color space conversion from RGB to YCbCr.

    Main Results:

    • The WASABI method demonstrated a significant speed-up, being 10-33 times faster than the look-up table method.
    • It achieved 2-7 times greater speed than the fast Fourier transform-based depth layer method.
    • Hologram generation in the YCbCr color space was approximately 1.5 times faster than in the RGB color space.
