One person can supervise ‘swarm’ of 100 unmanned autonomous vehicles, OSU research shows

A team of researchers at Oregon State University has demonstrated that a swarm of over 100 autonomous ground and aerial robots can be supervised by one person. The study used virtual reality interface I3 to enable high-level control, allowing the commander to deploy systems without manually driving each individual vehicle.

A rare recent case of retrovirus integration: An infectious gibbon ape leukaemia virus is colonising a rodent’s genome in New Guinea

Researchers have discovered a rare case of retrovirus integration in a rodent from New Guinea, revealing a new model for virus colonization. The white-bellied mosaic-tailed rat's genome contains the 'complete Melomys woolly monkey virus', which has characteristics of both exogenous and endogenous viruses.

Dynamic traveling time forecasting based on spatial-temporal graph convolutional networks

A novel dynamic routing planning framework DTT-STG was proposed to address limitations in existing research, integrating map-matching, road speed forecasting, and route planning. The framework captures dynamically changing spatial-temporal dependencies using diffusion convolution and attention mechanisms.
