A great influx of available computing resources has given rise to a large number of smart devices in everyday life. The functionality of smart devices vary from sensing to computation and are increasingly used for time-critical real-time applications. This Internet-of-Things (IoT) network of a variety of devices needs a robust communication network providing guarantees on system performance.We con
Mammographic sensitivity in breasts with higher density has been questioned. Higher breast density is also linked to an increased risk for breast cancer. Even though digital breast tomosynthesis (DBT) offers an attractive solution, for varied reasons it has not yet been widely adopted in screening. An alternative could be to boost the performance of standard mammography by using computer-aided det
Breast cancer screening is predominantly performed using digital mammography (DM), but higher sensitivity has been demonstrated with digital breast tomosynthesis (DBT). A partial DBT screening in selected groups with a clear benefit from DBT might be more feasible than a full implementation, and using artificial intelligence (AI) to select women for DBT might be a possibility. This study used data
We are developing a prototype system for simultaneous digital breast tomosynthesis (DBT) and mechanical imaging (MI). MI maps the local pressure distribution during clinical exams, to distinguish breast abnormalities from the normal tissue. Both DBT alone, and MI when combined with digital mammography, have demonstrated the ability to reduce false positives; however, the benefit of combining DBT w
Aims: Pediatric emergency department (ED) overcrowding is a challenge. This study was designed to evaluate if a hospital-integrated primary care unit (HPCU) reduces less urgent visits at a pediatric ED. Methods: This retrospective cross-sectional study was carried out at a university hospital in Sweden, where the HPCU, open outside office hours, had been integrated next to the ED. Children seeking
To systematically address non-technical engineering skills (NTES), six mandatory "Engineering Days" (Ing-dagar) were introduced in two bachelor programmes. The students were also allowed to perform voluntary activities leading to a Certification of Non-technical Engineering Competences, a certificate the students can attach to their CVs. To be certified, the student must have performed activities
This paper examines whether Sherlock Holmes’ “Science of Deduction and Analysis,” as reconstructed by Hintikka and Hintikka (in: Eco U, Sebeok TA (eds) The sign of three: Peirce, Dupin, Holmes, Indiana University Press, Bloomington, 1983), exemplifies a logic of discovery. While the Hintikkas claimed it does, their approach remained largely programmatic, and ultimately unsuccessful. Their reconstr
Fake canonizations are prevalent in the former communist countries wherein arts and culture in general may still function as propaganda weaponry at the hands of the sponsoring state. The public is almost eliminated from the process of canonization, as the publishing houses, art galleries, and cultural industries seldom survive and flourish from sales to a real public. As a rule, their rarefied pub
This chapter argues for a new listening practice for electroacoustic music (EAM) that I call “deep situated listening”. “Deep situated listening” builds on existing EAM-theories, aesthetics and practices – which I here collectively refer to as the “hearing heads” approach – but extends this approach by adding an explicitly feminist perspective. “Deep situated listening” combines Donna Haraway’s no
Experimental research was conducted to reveal the effects of nanofluids on heat transfer performance in a double-tube heat exchanger. With nanoparticle weight fraction of 0.5-2.0% and Reynolds number of 4500-14500, the flow resistance and heat transfer were analyzed by using six nanofluids, i.e., CuO-water, Al2O3-water, Fe3O4-water, ZnO-water, SiC-water, SiO2-water nanofluids. Results show that Si
Neurocognitive disorder encompasses many separate diagnoses, such as frontotemporal dementia (FTD), Alzheimer's disease (AD), Lewy body dementia (LBD), vascular dementia (VaD), and mixed dementia (MD). Because of the many variations between and within each subtype, it may be a challenge to clinically diagnose each condition. In a previous study on 176 dementia patients in a university hospital coh
Background and Purpose - Aortic valve stenosis may lead to atrial and ventricular remodeling, predisposes to atrial fibrillation, and may also be an independent risk factor of ischemic stroke. However, information on stroke rates among persons with aortic valve stenosis are sparse. We aimed to determine the incidence rates and relative risks of ischemic stroke in individuals with diagnosed aortic
The bone marrow microenvironment contains cellular niches that maintain the pool of hematopoietic stem and progenitor cells and support hematopoietic maturation. Malignant hematopoietic cells also co-opt normal cellular interactions to promote their own growth and evade therapy. In vivo systems used to study human hematopoiesis have been developed through transplantation into immunodeficient mouse
The paper reports an interview-based study that considers market driving and market-driven activities within the disaggregated components of the business model. The empirical study is of IKEA in China over a 10 year period. Market orientation is considered as a position on a continuum rather than as binary positions. The components of the business model are developed from the Osterwalder and Pigne
In this study, the thermal and hydraulic performances of six different printed circuit heat exchanger (PCHE) configurations with supercritical liquefied natural gas as the working fluid are studied by a numerical method. Firstly, the thermal and hydraulic performances of the PCHE with airfoil fins are investigated at different operating pressures, which indicate that the PCHE with airfoil fins has
We are very happy that someone has finally tried to make sense of rationalization. But we are worried about the representational structure assumed by Cushman, particularly the "boxology" belief-desire model depicting the rational planner, and it seems to us he fails to accommodate many of the interpersonal aspects of representational exchange.
Objectives and methods: We conducted a population-based study including 19 303 individuals diagnosed with MGUS in Sweden from 1985 to 2013, with the aim to determine whether a prior history of autoimmune disease, a well-described risk factor for MGUS is a risk factor for progression of MGUS to multiple myeloma (MM) or lymphoproliferative diseases (LPs). Using the nationwide Swedish Patient registr
We study shrinking target problems and the set of eventually always hitting points. These are the points whose first n iterates will never have empty intersection with the nth target for sufficiently large n. We derive necessary and sufficient conditions on the shrinking rate of the targets for to be of full or zero measure especially for some interval maps including the doubling map, some quadrat
The concept of critical performativity–efforts to make critical research more relevant for groups outside academia and develop and communicate action-relevant critical insights with some potential effect–has received considerable interest. Much of this has focused on debates about the core concept and principles. This paper argues for the need to “do”–more than talk about–critical performativity a
Deterministic Lateral Displacement (DLD) is a passive technique employed for particles sorting. We recently introduced a DLD device composed of arrayed three-dimensional metal-covered pillars that can be used to locally apply an electric field. With our system we can exploit the dielectrophoretic (DEP) effect to exert forces on the bioparticles to be sorted, thus dynamically tuning the critical si
