BACKGROUND: Recent research indicates long-term survival benefits of minimally invasive esophagectomy (MIE) compared with open esophagectomy (OE) for patients with esophageal and gastroesophageal junction (GEJ) cancers, but there is a need for more population-based studies.METHODS: We conducted a prospective population-based nationwide cohort study including all patients in Sweden diagnosed with e
We propose a generalisation of a behaviour tree and motiongenerator based robot arm policy representation for learning and solving tasks such as contact-rich tasks like peg insertion or pushing an object. We use planning to generate skill sequences needed to execute these tasks and rely on reinforcement learning to obtain parameters of the policy. We assume gaussian processes as a suitable method
We propose a pipeline to setup up robot systems for new tasks using symbolic planning, reasoning and reinforcement learning. Furthermore, we
Nickel (Ni)-promoted Molybdenum (Mo)-based catalysts are used for hydrotreatment processes in the chemical industry where the catalysts are exposed to high-pressure H2 at elevated temperature. In this environment, the catalyst transforms into the active phase, which involves the reduction of the oxide. Here, we report on the first in situ study on the reduction of alumina supported Ni- and Mo-base
In this paper we present some results on model based force estimation and how these estimates can be integrated in a common robot force control scheme. A generalization of the force estimation method proposed in [Hacksel and Salcudean, 1994] is done and a force observer able to follow ramp environmental forces is introduced. An extension of this method for robotic manipulators is also experimental
Emissions of biogenic volatile organic compounds (BVOCs) are a crucial component of biosphere-atmosphere interactions. In northern latitudes, climate change is amplified by feedback processes in which BVOCs have a recognized, yet poorly quantified role, mainly due to a lack of measurements and concomitant modeling gaps. Hence, current Earth system models mostly rely on temperature responses measur
Through reflections about a case study concerning an unfeasible, planned research study on nurses’ working days during the COVID-19 pandemic, the article aims to describe and discuss legal and ethical challenges when conducting European-based research together with nurses in third countries. The article highlights how the General Data Protection Regulation challenges EU and non-EU research collabo
BACKGROUND: Globally, 700 000 people die every year by suicide. Health care consultation patterns the period before suicide could be one potential way to identify people at risk for suicide. Therefore, this study examines health care patterns up to one year prior to the suicide by age, sex and prior diagnoses and specifically investigates if and how this differs from the general population of Skån
Background: Communication with patients and families about serious illness impacts quality of life and helps facilitate decision-making.Objective: To elucidate the pattern of communication about serious illness for patients who have died in an inpatient setting.Design: Three hundred patients from the Swedish Registry of Palliative Care 2015-2017 were randomly selected for manual chart review.Setti
Administrative law in the Swedish understanding forms the field of law regulating the activities of public authorities and others carrying out activities within the public sector. As in other Nordic and continental legal systems, the field is commonly divided into two parts. General administrative law (allmän förvaltningsrätt) covers the common principles and legal provisions applicable as default
Background: Cognitive reserve and resilience are terms used to explain interindividual variability in maintenance of cognitive health in response to adverse factors, such as brain pathology in the context of aging or neurodegenerative disorders. There is substantial interest in identifying tractable substrates of resilience to potentially leverage this phenomenon into intervention strategies. One
