Coral-bacterial communities before and after a coral mass spawning event on Ningaloo Reef. [PDF]

open access: yesPLoS ONE, 2012
Bacteria associated with three coral species, Acropora tenuis, Pocillopora damicornis and Tubastrea faulkneri, were assessed before and after coral mass spawning on Ningaloo Reef in Western Australia.

WiFiPi: Involuntary tracking of visitors at mass events [PDF]

open access: yes2013 IEEE 14th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM), 2013
To simulate crowds at mass events, realistic movement data of people is required. Despite their limited capacity for approximating real human mobility, synthetic movement models are traditionally used for this purpose. More realistic simulations can be achieved by using real-life movement data, gathered by observing people in the desired context.

COVID-safe behaviour before, during and after a youth mass gathering event: a longitudinal cohort study

open access: yesBMJ Open, 2022
Objective As mass gathering events resume in the wake of the COVID-19 pandemic, there is a pressing need to understand (a) engagement in COVID-safe behaviour at these events and (b) how attending a mass gathering impacts subsequent behaviours. This study

Constraint on the maximum mass of neutron stars using GW170817 event [PDF]

open access: yesPhysical Review D, 2019
We revisit the constraint on the maximum mass of cold spherical neutron stars coming from the observational results of GW170817. We develop a new framework for the analysis by employing both energy and angular momentum conservation laws as well as solid ...

Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A ∗ [PDF]

open access: yesClassical and quantum gravity, 2022
Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime.

Gastropods underwent a major taxonomic turnover during the end-Triassic marine mass extinction event.

open access: yesPLoS ONE, 2022
Based on an exhaustive database of gastropod genera and subgenera during the Triassic-Jurassic transition, origination and extinction percentages and resulting diversity changes are calculated, with a particular focus on the end-Triassic mass extinction ...

First Sagittarius A* Event Horizon Telescope Results. VI. Testing the Black Hole Metric [PDF]

open access: yesAstrophysical Journal Letters, 2022
Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies Einstein’s equations and does not have pathologies outside of the event ...

INFLUENCE OF ACQUAINTANCESHIP WITH A MASS EVENT RULES AND REGULATIONS ON THE PERCEPTION OF THE SELECTED ASPECTS OF SAFETY BY PARTICIPANTS [PDF]

open access: yesModern Management Review, 2017
Each and every mass event is an enormous logistics undertaking. The principal task of the organizers of a mass event is to make sure that those who participate in it are safe.

Foraging trip duration of honeybee increases during a poor air quality episode and the increase persists thereafter

open access: yesEcology and Evolution, 2021
Increased concentration of airborne particulate matter (PM) in the atmosphere alters the degree of polarization of skylight which is used by honeybees for navigation during their foraging trips.

Event-Triggered Adaptive Dynamic Programming Consensus Tracking Control for Discrete-Time Multiagent Systems

open access: yesComplexity, 2022
This paper proposes a novel adaptive dynamic programming (ADP) approach to address the optimal consensus control problem for discrete-time multiagent systems (MASs).
