Out-of-hospital cardiac arrest: Causes according to autopsy and electrocardiography - Analysis of 781 patients with neither hospital care nor prescribed medication during the preceding two years.

Background: There is a knowledge gap regarding aetiology of and potential for predicting out-of-hospital cardiac arrest (OHCA) among individuals who are healthy before the event.

Aim: To describe causes of OHCA and the potential for predicting OHCA in apparently healthy patients.

Methods: Patients were recruited from the Swedish Register of Cardiopulmonary Resuscitation from November 2007 to January 2011.

Predicting Agent Behaviour and State for Applications in a Roundabout-Scenario Autonomous Driving.

As human drivers, we instinctively employ our understanding of other road users' behaviour for enhanced efficiency of our drive and safety of the traffic. In recent years, different aspects of assisted and autonomous driving have gotten a lot of attention from the research and industrial community, including the aspects of behaviour modelling and prediction of future state. In this paper, we address the problem of modelling and predicting agent behaviour and state in a roundabout traffic scenario.

Intention Estimation Using Set of Reference Trajectories as Behaviour Model.

Autonomous robotic systems operating in the vicinity of other agents, such as humans, manually driven vehicles and other robots, can model the behaviour and estimate intentions of the other agents to enhance efficiency of their operation, while preserving safety. We propose a data-driven approach to model the behaviour of other agents, which is based on a set of trajectories navigated by other agents. Then, to evaluate the proposed behaviour modelling approach, we propose and compare two methods for agent intention estimation based on: (i) particle filtering; and (ii) decision trees.

Changes in medication preceding out-of-hospital cardiac arrest where resuscitation was attempted.

Objective: To describe recent changes in medication preceding out-of-hospital cardiac arrest (OHCA) where resuscitation was attempted.

Methods: OHCA victims were identified by the Swedish Cardiac Arrest Register and linked by means of their unique 10-digit personal identification numbers to the Prescribed Drug Register. We identified new claimed prescriptions during a 6-month period before the OHCA compared with those claimed in the period 12 to 18 months before.
