Flickering lights that are detected by the blue cones of the human visual system fuse to yield a steady sensation at much lower rates of flicker than do lights that are detected by the red or green cones. Yet, although blue-cone-detected lights flickering at 30-40 Hz appear to be steady, they are still able to interact with red- or green-cone-detected flickering lights to produce clearly detect...

During braking-to-stop manoeuvres in a fixed-base driving simulator, the paucity of visual and vestibular cues can lead to driver misperception and produce different patterns of braking response between real and simulated driving. For these reasons, drivers must adapt their behaviour in a simulator to affect a comfortable and efficient braking manoeuvre . Such behavioural adaptation is likely t...

OBJECTIVE To assess the nutrient profile of yoghurts and dairy desserts. DESIGN Nutrition information panels and product labels on yoghurts and dairy desserts offered for sale were surveyed in 2005 and 2008 and nutrients analysed by two nutrient profiling systems. SETTING A large supermarket in metropolitan Melbourne, Australia. RESULTS In total, 248 and 140 dairy snacks (yoghurt, fromage...

Since traffic jams are ubiquitous in the modern world, optimizing the behavior of traffic lights for efficient traffic flow is a critically important goal. Though most current traffic lights use simple heuristic protocols, more efficient controllers can be discovered automatically via multiagent reinforcement learning, where each agent controls a single traffic light. However, in previous work ...

OBJECTIVE Early recognition and treatment of febrile children with serious infections (SI) improves prognosis, however, early detection can be difficult. We aimed to validate the predictive rule-in value of the National Institute for Health and Clinical Excellence (NICE) most severe alarming signs or symptoms to identify SI in children. DESIGN, SETTING AND PARTICIPANTS The 16 most severe ("re...

Autonomous driving at intersections is one of the most complicated and accident-prone traffic scenarios, especially with mixed participants such as vehicles, bicycles pedestrians. The policy should make safe decisions to handle dynamic conditions meet requirements on-board computation. However, current researches focuses on simplified considering only surrounding vehicles idealized lights. This...
