Safety verification of a fault tolerant reconfigurable autonomous goal-based robotic control system [PDF]
Fault tolerance and safety verification of control systems are essential for the success of autonomous robotic systems. A control architecture called Mission Data System (MDS), developed at the Jet Propulsion Laboratory, takes a goal-based control ...

Abstract Background and Purpose Alarming trends show that vaping e‐cigarettes containing synthetic cannabinoid receptor agonists, such as JWH‐018, is increasing among youth. However, the effects of these trends are unclear in both sexes. We therefore characterized the neuropharmacological effects of adolescent JWH‐018 inhalation in male and female rats.

A USV-UAV Cooperative Trajectory Planning Algorithm with Hull Dynamic Constraints
Efficient trajectory generation in complex dynamic environments remains an open problem in the operation of an unmanned surface vehicle (USV). The perception of a USV is usually interfered by the swing of the hull and the ambient weather, making it ...

Background and Purpose 3,4‐Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, is a psychostimulant with entactogenic properties and known to induce arousal and euphoria. As an amphetamine derivate, MDMA acts on the monoamine systems in the brain and stimulates release of dopamine (DA), noradrenaline (NA) and serotonin (5‐HT), yet their ...

Ultrasonic vocalization of pup and adult fat-tailed gerbils (Pachyuromys duprasi).
Ultrasonic vocalizations (USVs) of laboratory rodents indicate animal emotional arousal and may serve as models of human disorders. We analysed spectrographically USV calls of pup and adult fat-tailed gerbils Pachyuromys duprasi during 420-s tests ...

Abstract The protection of civilian harbours has received an increasing interest after September 11th. One of the areas currently under major investigation is the use of a team of Unmanned Surface Vehicles (USVs), which could be exploited for patrolling purposes and to investigate suspect situations, increasing the effectiveness of the harbor ...

A DDPG-Based USV Path-Planning Algorithm
Path planning is crucial in the automatic navigation of USVs (unmanned underwater vehicles), which directly affects the operational efficiency and safety of USVs. In this paper, we propose a path-planning algorithm based on DDPG (Deep Deterministic Policy Gradient) and make a detailed comparison with the traditional A-Star algorithm and the recent ...

ABSTRACT The rise in obesity rates in India in the past 3–4 decades is alarming and obesity management needs transformation. A significant barrier is that obesity is often viewed in India as a lifestyle condition rather than a chronic disease, despite broad international recognition of this status.
