Heart rate response to apnea in air and water during rest and steady-state exercise was studied in 20 male college students Significant bradycardia (p < 0.05) due to apnea was observed at rest and during exercise A significant increase in bradycardia (P < 0 01 ) due to apneic face immersion in water was observed at rest and during exercise.

Advanced Functional Materials, 2022
Swelling is ubiquitous for conventional hydrogels but is not favorable for many situations, especially underwater applications. In this study, an anti‐swelling and mechanically robust polyacrylic acid (PAAc)/gelatin composite hydrogel is reported with a ...

Non-Uniform Illumination Underwater Image Restoration via Illumination Channel Sparsity Prior
IEEE transactions on circuits and systems for video technology (Print)Underwater image quality is seriously degraded due to the insufficient light in water. Although artificial illumination can assist imaging, it often brings non-uniform illumination phenomenon.

Underwater Image Enhancement Using a Multiscale Dense Generative Adversarial Network
IEEE Journal of Oceanic Engineering, 2020Underwater image enhancement has received much attention in underwater vision research. However, raw underwater images easily suffer from color distortion, underexposure, and fuzz caused by the underwater scene.

Human-Visual-System-Inspired Underwater Image Quality Measures
IEEE Journal of Oceanic Engineering, 2016Underwater images suffer from blurring effects, low contrast, and grayed out colors due to the absorption and scattering effects under the water. Many image enhancement algorithms for improving the visual quality of underwater images have been developed.

Underwater empires [Underwater research]
Engineering & Technology, 2007Alongside the space race, which has been making headlines around the world over the last 50 years, there is another area of superpowers' rivalry that lies beneath the oceans. The author appraises the latest moves of supremacy-driven 'underwater empires' (underwater research) and the technology behind them.
