Personalised breast cancer screening with selective addition of digital breast tomosynthesis through artificial intelligence

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

Evaluation of a flat fielding method for simultaneous DBT and MI acquisition

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

Adjacent Primary Care May Reduce Less Urgent Pediatric Emergency Department Visits

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

Certification of students in non-technical engineering skills : What do the companies think?

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

The Holmesian logician : Sherlock Holmes’ “Science of Deduction and Analysis” and the logic of discovery

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

For the sake of a liberalized Romanian culture! what about an interdisciplinary and transdisciplinary canon instead of the isolated monopolies with a subscription to the state budget?

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

Deep Situated Listening Among Hearing Heads and Affective Bodies

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

Heat transfer performance and friction factor of various nanofluids in a double-tube counter flow heat exchanger

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

Clinicopathological concordance in cognitive disease diagnostics

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

Incidence of Ischemic Stroke in Individuals with and without Aortic Valve Stenosis : A Danish Retrospective Cohort Study

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

Engineering human hematopoietic environments through ossicle and bioreactor technologies exploitation

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 changing marketing orientation within the business model of an international retailer–IKEA in China over 10 years

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

Investigation on Thermal-Hydraulic Performance in a Printed Circuit Heat Exchanger with Airfoil and Vortex Generator Fins for Supercritical Liquefied Natural Gas

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

Letting rationalizations out of the box

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.

Autoimmune disease is associated with a lower risk of progression in monoclonal gammopathy of undetermined significance

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

Shrinking targets and eventually always hitting points for interval maps

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

Critical performativity in practice : the chronicle as a vehicle for achieving social impact

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 systems with arrayed three-dimensional electrodes for tunable particle sorting

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

Deep Learning Algorithm for Satellite Imaging Based Cyclone Detection

Satellite images are primary data in weather prediction modeling. Deep learning-based approach, a viable candidate for automatic image processing, requires large sets of annotated data with diverse characteristics for training purposes. Accuracy of weather prediction improves with data having a relatively dense temporal resolution. We have employed interpolation and data augmentation techniques fo

Ökande antal övervintrande skogsfåglar i lappland 1986–2017 visar starkare samband med skogens utveckling än lokalt väder

After a long period of decline, the number of forest birds has increased in Sweden in recent decades. Whether this trend is due to an increase in forested area, forest quality, climate change, or a combination of these factors, remains unclear. Here, we compared forest bird data from a local winter point count route around Storuman in Swedish Lapland between 1986 and 2017, with the development of
