The influence of scuba diving experience on divers' perceptions, and its implications for managing diving destinations.

open access: yesPLoS ONE, 2019
Scuba diving experience-which can include accumulated diving experience and familiarity with a diving location-is an important descriptor of diver specialisation and behaviour.

Diving into traversable wormholes [PDF]

open access: yes, 2017
We study various aspects of wormholes that are made traversable by an interaction beween the two asymptotic boundaries. We concentrate on the case of nearly‐ AdS2 gravity and discuss a very simple mechanical picture for the gravitational dynamics.

Flow, satisfaction and storytelling: a causal relationship? Evidence from scuba diving in Turkey

open access: yesCurrent Issues in Tourism, 2020
The popularity of activity-based tourism is often explained by experiential concepts such as flow. By using a mixed-methods approach, this study investigates how the storytelling intentions of scuba diving tourists are influenced by their flow experience.

Extreme diving in mammals: first estimates of behavioural aerobic dive limits in Cuvier's beaked whales

open access: yesJournal of Experimental Biology, 2020
We analysed 3680 dives from 23 satellite-linked tags deployed on Cuvier's beaked whales to assess the relationship between long duration dives and inter-deep dive intervals and to estimate aerobic dive limit (ADL).

Attentive Spatio-Temporal Representation Learning for Diving Classification [PDF]

open access: yes2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2019
Competitive diving is a well recognized aquatic sport in which a person dives from a platform or a springboard into the water. Based on the acrobatics performed during the dive, diving is classified into a finite set of action classes which are ...

Primal Heuristics for Branch and Price: The Assets of Diving Methods

open access: yesINFORMS journal on computing, 2019
Primal heuristics have become an essential component in mixed integer programming (MIP) solvers. Extending MIP based heuristics, our study outlines generic procedures to build primal solutions in the context of a branch-and-price approach and reports on ...

Benefits of Escin for Decompression Sickness in Bama Pigs by Endothelial-Targeting Protection

open access: yesFrontiers in Physiology, 2019
Endothelial dysfunction has been considered as pivotal in the pathogenesis of decompression sickness (DCS) and contributes substantively to subsequent inflammatory responses.

A practical primer for image-based particle measurements in microplastic research

open access: yesMicroplastics and Nanoplastics, 2023
Microplastics have been detected in large numbers around the world. Not only their sheer number threatens ecosystems, their biodiversity, and human health, but risks are also posed by particle characteristics such as size and shape.

Diving behaviour of Cuvier's beaked whales (Ziphius cavirostris) off Cape Hatteras, North Carolina

open access: yesRoyal Society Open Science, 2019
Cuvier's beaked whales exhibit exceptionally long and deep foraging dives. The species is little studied due to their deep-water, offshore distribution and limited time spent at the surface.

Shining new light on mammalian diving physiology using wearable near-infrared spectroscopy

open access: yesPLoS Biology, 2019
Investigation of marine mammal dive-by-dive blood distribution and oxygenation has been limited by a lack of noninvasive technology for use in freely diving animals.
