A chronicle describing the historical context and the development of ideas and experiments leading to the discovery of the back-bending phenomenon in rapidly rotating atomic nuclei some 50 years ago is presented. The moment of inertia of some atomic nuclei increases anomalously at a certain rotational frequency, revealing important clues to our understanding of nuclear structure. I highlight the d
Through the influence of neoliberal ideas, many critical infrastructures that used to be under public ownership have been opened up for market competition. Using the Swedish railway system as a case, this paper empirically explores whether such reforms have given rise to common-pool resource problems, and discusses possible implications. The results show that institutional restructuring has create
Pseudomyxoma Peritonei (PMP) and Peritoneal Mesothelioma (PM) are both rare peritoneal malignancies. Currently, affected patients may be treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy offering long-term survival or even cure in selected patients. However, many issues regarding the optimal treatment strategy are currently under debate. To aid physicians involved in
Background: This article examines the impact of parental death in childhood, adolescence, and adulthood on male and female age at marriage in the Netherlands in the period 1850–1940. It follows an interdisciplinary approach as it considers explanations based on social and demographic history and evolutionary biology.Objective: We study the classical historical framework in more detail by controlli
Swedish filmmaker Jan Halldoff's fiction film Korridoren (The Corridor) premiered in 1968 to a mainly positive Swedish reception. Shot at Karolinska Hospital and criticizing the Swedish healthcare system, the film became much debated and can furthermore be seen as a turning point in Swedish film history regarding the portrayal of medical institutions and professionals. In this article, the film an
OBJECTIVES: (1) To assess prognostic factors for patient-reported outcome measures (PROMs) and physical activity 2 to 10 years after anterior cruciate ligament reconstruction (ACLR) or anterior cruciate ligament (ACL) injury, and (2) to assess differences in prognostic factors between patients treated with ACLR and with rehabilitation alone.DESIGN: Prognosis systematic review.LITERATURE SEARCH: Sy
In the media and communications field, research investigating the digital media engagements of very young children at home has largely been restricted to survey methods relying on parental self-reports. Recognizing that qualitative approaches can provide insights in families’ practices, values, and attitudes, we argue for the fruitfulness of an ethnographic perspective, drawing on three cases from
A polymer electrolyte fuel cell (PEFC) is an electrochemical device that converts the chemical energy presents in the hydrogen into electricity and heat having as by product only water. The energy conversion process is carried out in a clean and noiseless manner. Depending on the applications, a PEFC works at different operating temperature. In this study, the internal resistance of a PEFC is eval
During World War II, middle-distance runner Gunder Hägg set 15 world records and became a media sport star of unprecedented magnitude in Sweden. This article turns attention to the role of radio broadcasts in the formation of Swedish “Hägg mania” 1941–45. When analyzed in terms of blindness, liveness and co-presence, radio broadcasts from this era reveal that radio announcers actively engaged with
Shiga toxin is the main virulence factor of non-invasive enterohemorrhagic Escherichia coli strains capable of causing hemolytic uremic syndrome. Our group has previously shown that the toxin can reach the kidney within microvesicles where it is taken up by renal cells and the vesicles release their cargo intracellularly, leading to toxin-mediated inhibition of protein synthesis and cell death. Th
BACKGROUND: Heart rate control in atrial fibrillation (AF) is typically assessed by 24-hour electrocardiography (ECG). There are scarce data on the use of 24-hour ECG parameters to predict mortality in AF.AIMS: We aimed to identify 24-hour ECG parameters that predict mortality in AF.METHODS: We enrolled 280 ambulatory patients (mean [SD] age, 72.0 [8.7] years; 57.9% men) with permanent or persiste
In this paper, we investigate the usefulness of adding a box-constraint to the minimization of functionals consisting of a data-fidelity term and a total variation regularization term. In particular, we show that in certain applications an additional box-constraint does not effect the solution at all, i.e., the solution is the same whether a box-constraint is used or n
IMPACT: The authors recommend that politicians and public managers consider the possible benefits and critical issues connected to the creation of holding companies at the local government level. On the one hand, municipal holding companies can be useful for steering and controlling municipal corporations; on the other hand, they can have the downside of adding another level of governance.
Value-added bioproducts are linked to the expansion of lignocellulosic biorefineries based on agro-industrial waste and local economic growth. Thus, the aim of this study was to pretreat rice hull (RH), a highly recalcitrant biomass, with saturated steam and convert it to lactic acid (LA). Strategically, the individual fractions and the blend of detoxified liquor and water-insoluble solids were us
Proton-γ coincidences from (d,p) reactions between a Ni66 beam and a deuterated polyethylene target have been analyzed with the inverse-Oslo method to find the nuclear level density (NLD) and γ-ray strength function (γSF) of Ni67. The Ni66(n,γ) capture cross section has been calculated using the Hauser-Feshbach model in TALYS using the measured NLD and γSF as constraints. The results confirm that
Tree roots and their fungal symbionts mediate the response of rhizosphere soil organic carbon (SOC) decomposition to climate warming, specifically the temperature sensitivity of soil microbial respiration (Q10), which is a critical parameter for projecting the magnitude of terrestrial soil C-climate feedbacks. However, the intensity of the rhizosphere effects (RE; rhizosphere soils vs. bulk soils)
A perennial issue of survey research is that some participants do not answer all questions. Interactive follow-up requests are a novel approach to this problem. However, research on their effectiveness is scarce. I present the most comprehensive study yet on the effects of interactive requests on item non-responses. Theoretically, I outline different pathways whereby follow-up requests may effecti
We study the problem of computing the Voronoi diagram of a set of.n2 points with.O(log n)-bit coordinates in the Euclidean plane in a substantiallysublinear in . n number of rounds in the congested clique model with . n nodes.Recently, Jansson et al. have shown that if the points are uniformly at random distributed in a unit square then their Voronoi diagram within the square can be computed in.O(
We examine the effect of screen-based activities on obesity and mental well-being for children, using a large survey dataset representative of the UK population and an event study model that exploits exogenous variation in the entry date of the digital television transition in the UK. The digital transition increased the number of available free television channels from 5 to 40, leading to a rise
CONTEXT: Viral/bacterial infection is proposed as a trigger for the autoimmune thyroid diseases (AITD): Graves' disease (GD) and Hashimoto's thyroiditis (HT). Previous studies in European Caucasian AITD subjects found higher birth rates in the autumn/winter, suggesting those born in the autumn/winter experience increased viral/bacterial exposure after birth, impacting upon immune system developmen
