Continuous Autonomous Ship Learning Framework for Human Policies on Simulation

open access: yesApplied Sciences, 2022
Considering autonomous navigation in busy marine traffic environments (including harbors and coasts), major study issues to be solved for autonomous ships are avoidance of static and dynamic obstacles, surface vehicle control in consideration of the ...

Analysis of the Vessels’ Service Time in the Port of Gdańsk, Based on the Time Registration of Ships Entries and Departures, as a Proposition of Multi-aspect Method of Port Monitoring [PDF]

open access: yesTransNav, 2020
The aim of the paper is to analyse the length of time that ships spend in the Port of Gdansk. It is based on the examination of the time when ships come into and leave the port.

LONG-TERM MARINE TRAFFIC MONITORING FOR ENVIRONMENTAL SAFETY IN THE AEGEAN SEA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
The Aegean Sea is characterized by an extremely high marine safety risk, mainly due to the significant increase of the traffic of tankers from and to the Black Sea that pass through narrow straits formed by the 1600 Greek islands.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Stability Analysis of a Bulk Carrier under Damage Scenarios during the Loading of Polymetallic Nodules in the Clarion–Clipperton Zone [PDF]

open access: yesTransNav
A potential consequence of loading polymetallic nodules (PMNs) in a marine environment is liquefaction. During loading operations in the Clarion–Clipperton Zone (CCZ), the ship is exposed to cyclic rolling and pitching, which increases the risk of cargo ...

Ship Strike Risk for Fin Whales (Balaenoptera physalus) Off the Garraf coast, Northwest Mediterranean Sea

open access: yesFrontiers in Marine Science, 2022
Ship strikes are a widespread conservation issue for many cetacean species globally. Population level impacts depend on the occurrence and severity of collisions, which may lead to life altering injuries or fatalities.

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

open access: yesAdvanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.
