- Embedded systems are specialized computers used in larger systems or machines to control equipments such as automobiles, home appliances, communication, control and office machines. Such pervasivity is particularly evident in immersive realities, i.e., scenarios in which invisible embedded systems need to continuously interact with human users, in order to provide continuous sensed information and to react to service requests from the users themselves. The SM4All project investigates an innovative middleware platform for inter-working of smart embedded services in immersive and person-centric environments, through the use of composability and semantic techniques for dynamic service reconfiguration. This is applied to the challenging scenario of private houses and home-care assistance in presence of users with different abilities and needs (e.g., young, able-bodied, aged and disabled). This paper presentes a brief overview of the SM4All system architecture.

- The aim of this study was to investigate factors predictive for ‘death at home’ for patients admitted to an advanced medical home care unit in Stockholm, Sweden, with a focus on possible gender differences. In addition, place of death in relation to the patient’s wishes was studied.MethodA retrospective review of medical records of all 456 deceased patients, 233 men and 223 women, admitted to the unit during 2017 was performed. Data on age, diagnosis, living conditions, Swedish language skills, desired place of death (if stated) and place of death were retrieved from the patients’ charts.ResultsA total of 114 of 456 patients died at home (25%). The probability of ‘death at home’ was independent of gender, age, diagnosis, living conditions and Swedish language skills. In a binary logistic regression model, the only factor significantly associated with death at home was ‘the wish to die at home’ (p<0.001). In the study population, 154 patients (34%) had expressed a preferred place of death, 116 (75%) wanted to die at home and 38 (25%) wanted to die in hospice. Of all patients who expressed a preferred place of death, 80% (n=123) had their wishes fulfilled and there were no differences between the sexes.ConclusionThis study indicates equal opportunities regarding the possibility to die at home for patients admitted to advanced medical home care. It emphasises the importance of asking patients where they want to be at the end of life, as it was the foremost prognostic factor for place of death.

Recent advances in understanding secondary organic aerosol : Implications for global climate forcing
- 2017

In: Reviews of Geophysics. - 8755-1209. ; 55:2, s. 509-559
-
Journal article (peer-reviewed)abstract
- Anthropogenic emissions and land use changes have modified atmospheric aerosol concentrations and size distributions over time. Understanding preindustrial conditions and changes in organic aerosol due to anthropogenic activities is important because these features (1) influence estimates of aerosol radiative forcing and (2) can confound estimates of the historical response of climate to increases in greenhouse gases. Secondary organic aerosol (SOA), formed in the atmosphere by oxidation of organic gases, represents a major fraction of global submicron-sized atmospheric organic aerosol. Over the past decade, significant advances in understanding SOA properties and formation mechanisms have occurred through measurements, yet current climate models typically do not comprehensively include all important processes. This review summarizes some of the important developments during the past decade in understanding SOA formation. We highlight the importance of some processes that influence the growth of SOA particles to sizes relevant for clouds and radiative forcing, including formation of extremely low volatility organics in the gas phase, acid-catalyzed multiphase chemistry of isoprene epoxydiols, particle-phase oligomerization, and physical properties such as volatility and viscosity. Several SOA processes highlighted in this review are complex and interdependent and have nonlinear effects on the properties, formation, and evolution of SOA. Current global models neglect this complexity and nonlinearity and thus are less likely to accurately predict the climate forcing of SOA and project future climate sensitivity to greenhouse gases. Efforts are also needed to rank the most influential processes and nonlinear process-related interactions, so that these processes can be accurately represented in atmospheric chemistry-climate models.
