TL;DR: On 5 February 2020, in Yokohama, Japan, a cruise ship hosting 3,711 people underwent a 2-week quarantine after a former passenger was found with COVID-19 post-disembarking, and the delay-adjusted asymptomatic proportion of infections, along with the infections’ timeline were derived.

TL;DR: Estimates of the transmissibility and virulence of COVID-19 in Wuhan City, China during January-February, 2020 are derived by reconstructing the underlying transmission dynamics using multiple data sources using an ecological modelling approach.

TL;DR: The delay-adjusted asymptomatic proportion of the positive COVID-19 infections onboard the Princess Cruises ship along with the timeline of infections was estimated at 17.9% (95% CrI: 15.5%-20.2%), with most of the infections occurring before the start of the 2-week quarantine.

TL;DR: This study derives estimates of the transmissibility and virulence of COVID-19 in Wuhan City, China, by reconstructing the underlying transmission dynamics using multiple data sources using an ecological modeling approach suitable to infer epidemiological parameters with quantified uncertainty from partial observations collected by surveillance systems.

TL;DR: The spike activity of brain neurons at the time of spontaneous initiation of walking in the crayfish Procambarus clarkii is investigated and neuronal signals indicative of readiness or preparatory activities in the vertebrate brain that precede the onset of voluntary actions are found.
