Learning to Adapt the Parameters of Behavior Trees and Motion Generators (BTMGs) to Task Variations

The ability to learn new tasks and quickly adapt to different variations or dimensions is an important attribute in agile robotics. In our previous work, we have explored Behavior Trees and Motion Generators (BTMGs) as a robot arm policy representation to facilitate the learning and execution of assembly tasks. The current implementation of the BTMGs for a specific task may not be robust to the ch

Impact of ground plane scattering on performance of reconfigurable intelligent surface

Reconfigurable intelligent surfaces (RISs) are being considered for 6G as they can facilitate favourable radio channels. To rigorously model the characteristics of an array antenna-based RIS, this paper proposes an approach to separately evaluatescatterings from the antenna elements and ground plane of RIS. Simulation results show that, depending on the absolute phases of variable loads in the RIS

Integrering eller exkludering? Svalövs kommuns strategier för bosättning av flyktingar och hemlösa kommuninvånare

Det övergripande syftet med denna studie, som ingick i forskningsprojektet Skånska hem: mottagande, etablering eller exkludering – hemlöshetspolitik och strategier för flyktingars bosättning, var att undersöka och beskriva Svalövs kommuns strategier för mottagande och bosättning av flyktingar och hemlösa kommuninvånare under åren 2018 till och med 2022. Forskningsprojektet ska ses mot bakgrund av

RECO: Resilient Communities by Sustainable Welfare Transformation

Marcus Knutagård, Arne Kristiansen & Cecilia HeuleRECO: Resilient Communities by Sustainable Welfare TransformationHomelessness is an extensive societal problem in Sweden which poses major challenges for the social services in developing sustainable and effective methods that can meet the service user’s needs.

Influenza-associated invasive aspergillosis in patients admitted to the intensive care unit in Sweden : a prospective multicentre cohort study

BACKGROUND: The purpose of this study was to prospectively investigate the incidence of influenza-associated pulmonary aspergillosis (IAPA) in influenza patients admitted to intensive care units in Sweden.METHODS: The study included consecutive adult patients with PCR-verified influenza A or B in 12 Swedish intensive care units (ICUs) over four influenza seasons (2019-2023). Patients were screened

Cardiovascular Outcomes in Adults with Coronary Artery Disease and Obstructive Sleep Apnea with versus without Excessive Daytime Sleepiness in the RICCADSA Clinical Trial

Rationale: Recent randomized controlled trials did not show cardiovascular benefits of continuous positive airway pressure (CPAP) in adults with coronary artery disease (CAD) and obstructive sleep apnea (OSA) in intention-to-treat analyses. It has been argued that exclusion of patients with OSA with excessive daytime sleepiness (EDS), who may be most likely to benefit from CPAP treatment, may be a

Seasonality and competition select for variable germination behavior in perennials

The occurrence of within-population variation in germination behavior and associated traits such as seed size has long fascinated evolutionary ecologists. In annuals, unpredictable environments are known to select for bet-hedging strategies causing variation in dormancy duration and germination strategies. Variation in germination timing and associated traits is also commonly observed in perennial

Making in turbulent times:new insights into late 18th-and early 19th-century ceramic crafts and connectivity in the Magaliesberg region

Among Simon Hall's influential contributions to historical archaeology are two research agendas: The need to focus attention on lower scalar levels of analysis, and broadening the concept of ceramic style to include less visible technological qualities. The latter is of particular importance to the stylistically bland and less decorated assemblages from the 18th and 19th centuries. Combining and d

Gender Representation and Leadership in Local Transport Decision-Making Positions

This paper aims to analyse and further capture nuances of gender representation in local political decision-making bodies, focusing on implications for transport policy. Since gender is highly relevant for both attitudes towards transport policy as well as political votes, data on the gender and political colour of executives (members of presidiums) of transport-related committees, councils, and b

High risk of stroke in ANCA-Associated vasculitis-a population-based study

Objective: To determine the incidence rate, predictors and outcome of stroke in a population-based cohort of individuals with ANCA-Associated vasculitis (AAV). Methods: The study included 325 patients diagnosed with AAV from 1997 through 2016 in a defined geographic area of Sweden. Patients who suffered a stroke were identified from Riksstroke, a national Swedish stroke register established in 199

Native lignin extraction from soft- and hardwood by green and benign sub/supercritical fluid extraction methodologies

Lignin constitutes an impressive resource of high-value low molecular weight compounds. However, robust methods for isolation of the extractable fraction from lignocellulose are yet to be established. In this study, supercritical fluid extraction (SFE) and CO2-expanded liquid extraction (CXLE) were employed to extract lignin from softwood and hardwood chips. Ethanol, acetone, and ethyl lactate wer

Status improvement in water and wastewater fixed facilities : Success and challenges of 11 Swedish water utilities as case studies

Reinvestment in water and wastewater (WW) facilities is a challenge for Swedish water utilities. Nationwide, 4% of 184 organizations meet the requirements for a sustainable WW facility status according to the sustainability index (SI), the Swedish benchmark system. Eleven Swedish municipal WW organizations that had improved the status of their facilities were examined and are presented as good lea

Impact of the Economic Crisis on Body Mass Index in Spain : An Intersectional Multilevel Analysis Using a Socioeconomic and Regional Perspective

The Great Recession hit Spain deteriorating the living conditions of many Spanish people, increasing the prevalence of several chronic health issues, including obesity, and affecting health inequalities. We analyse the impact of this economic crisis on body mass index (BMI) disparities in Spain, from two perspectives: the socioeconomic and the territorial, through the application of an intersectio

Low Load Ignitability of Methanol in a Heavy-Duty Compression Ignition Engine

An increasing need to lower greenhouse gas emissions, and so move away from fossil fuels like diesel and gasoline, has greatly increased the interest for methanol. Methanol can be produced from renewable sources and eliminate soot emissions from combustion engines [1]. Since compression ignition (CI) engines are used for the majority of commercial applications, research is intensifying into the us

A Description of the Yield of Genetic Reinvestigation in Patients with Inherited Retinal Dystrophies and Previous Inconclusive Genetic Testing

In the present era of evolving gene-based therapies for inherited retinal dystrophies (IRDs), it has become increasingly important to verify the genotype in every case, to identify all subjects eligible for treatment. Moreover, combined insight concerning phenotypes and genotypes is crucial for improved understanding of thevisual impairment, prognosis, and inheritance. The objective of this study
