Spectral flow for pair compatible equipartitions

We show that a recent spectral flow approach proposed by Berkolaiko–Cox–Marzuola for analyzing the nodal deficiency of the nodal partition associated to an eigenfunction can be extended to more general partitions. To be more precise, we work with spectral equipartitions that satisfy a pair compatible condition. Nodal partitions and spectral minimal partitions are examples of such partitions. Along

Survival, causes of death and recurrence up to 3 years after stroke : A population-based study

Background and purpose: Up-to-date population-based information about long-term survival, causes of death and recurrence after stroke is needed. Methods: Four hundred consecutive individuals in a population-based cohort of first-ever stroke between 2015 and 2016 in Lund, Sweden, were followed up to 3 years regarding (i) survival (Swedish Population Register); (ii) causes of death (Swedish Causes o

MRI Characteristics of Pediatric Renal Tumors : A SIOP-RTSG Radiology Panel Delphi Study

Background: The SIOP-Renal Tumor Study Group (RTSG) does not advocate invasive procedures to determine histology before the start of therapy. This may induce misdiagnosis-based treatment initiation, but only for a relatively small percentage of approximately 10% of non-Wilms tumors (non-WTs). MRI could be useful for reducing misdiagnosis, but there is no global consensus on differentiating charact

Online conferencing in the midst of COVID-19 : an “already existing experiment” in academic internationalization without air travel

Academia, as many other sectors, has faced wide-ranging disruptions due to COVID-19, with teaching and research activity conducted entirely online in many countries. Before the pandemic grounded travel, academics were often hypermobile, some traveling more than 150,000 kilometers per year for conferences, board meetings, collaborations, fieldwork,seminars, and lectures. It is no surprise then that

Testing Self-Adaptive Software with Probabilistic Guarantees on Performance Metrics : Extended and Comparative Results

This paper discusses methods to test the performance of the adaptation layer in a self-adaptive system. The problem is notoriously hard, due to the high degree of uncertainty and variability inherent in an adaptive software application. In particular, providing any type of formal guarantee for this problem is extremely difficult. In this paper we propose the use of a rigorous probabilistic approac

Are structural abnormalities on knee MRI associated with osteophyte development? Data from the Osteoarthritis Initiative

Objective: To assess which structural abnormalities on knee MRI are associated with development of osteophytes in middle-aged subjects without radiographic knee osteoarthritis. Design: We included subjects from the Osteoarthritis Initiative, aged 40–55 years, Kellgren & Lawrence grade 0 in both knees, and knee MRIs from both knees available at baseline, 24, 48 and 72 months. Structural exposur

High cycle fatigue behaviour of autoclave-cured woven carbon fibre-reinforced polymer composite gears

The high cycle fatigue behaviour of autoclave-cured carbon fibre-reinforced polymer (CFRP) composite gears is investigated. The CFRP gears were milled from a composite plate and tested in mesh with a steel drive gear under five torque loads ranging between 0.4 and 0.8 Nm in unlubricated conditions. A detailed gear damage analysis is conducted by employing scanning electron microscopy and high-reso

Internationalisation of higher education: Impacts, challenges and future possibilities

This special issue follows on from a special call for contributions tothe ECER 2016 conference in Dublin on the need to rethink andreconceptualise internationalisation in higher education (HE). Thepapers in this special issue contribute to a critically reflectiveinterdisciplinary discussion on the phenomena ofinternationalisation in terms of the evolution of the structures,systems, and functions o

The micrometeorite flux to Earth through the Phanerozoic Eon : Reconstructed using sediment-dispersed extraterrestrial spinels

The purpose of this thesis is to add an astronomical component to the history and evolution of Earth by reconstructing the micrometeorite flux to Earth at different time intervals during the Phanerozoic Eon, using sediment-dispersed extraterrestrial spinel group minerals as a proxy. Chromite and chrome spinel are common refractory members of the spinel group, occurring in both extraterrestrial and

Strengthening antimicrobial resistance diagnostic capacity in rural rwanda : A feasibility assessment

Introduction: Antimicrobial resistance (AMR) is a global public health threat. Worse still, there is a paucity of data from low-and middle-income countries to inform rational antibiotic use. Objective: Assess the feasibility of setting up microbiology capacity for AMR testing and estimate the cost of setting up microbiology testing capacity at rural district hospitals in Rwanda. Methods: Laborator

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries : a multicentre, international, prospective cohort study

Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anoma

Behavioural Insights into Personal Electronics Repair in Sweden

Sweden is actively seeking to scale up repair activities as part of its strategy to reduce waste, transition to a circular economy, and achieve zero net emissions by 2045. In the last couple of years, several new policies to promote consumer repairs have been adopted or proposed in Sweden. However, very little is known about the socio-cultural factors that shape people's decision to repair their p

Repair in the Circular Economy: Towards a National Swedish Strategy

Extending the lifetime of products is seen as a key objective for realising the vision of a Circular Economy. One way to increase the lifespan of products is to enable more repair activities. However, consumers encounter a variety of barriers for repairs, prompting public authorities in Europe and the US to adopt or propose policies in support of consumer repairs. Sweden has recently adopted a cir

Trust Matters : the Impact of In-group and Outgroup Trust on Nativism and Civicness

ObjectivesThe objectives of this study are threefold: first, we separate trust into a two-dimensional concept: ingroup trust and outgroup trust. Second, we apply both types of trust to two dependent variables: nativism and civicness, hypothesizing that respondents with ingroup trust should display higher degrees of nativism and lower degrees of civicness while the opposite should apply to responde

Anchoring the Experts : Using Vignettes to Compare Party Ideology Across Countries

Expert surveys are a valuable, commonly used instrument to measure party positions. Some critics question the cross-national comparability of these measures, though, suggesting that experts may lack a common anchor for fundamental concepts such as economic left–right. Using anchoring vignettes in the 2010 Chapel Hill Expert Survey, we examine the extent of cross-national difference in expert ideol

The European Common Space : Extending the Use of Anchoring Vignettes

In this article, we combine advances in both survey research and scaling techniques to estimate a common dimension for political parties across the member states of the European Union. Most previous scholarship has either ignored or assumed cross-national comparability of party placements across a variety of dimensions. The 2010 wave of the Chapel Hill Expert Survey includes anchoring vignettes wh

What's Trust Got To Do With It? : The Effects of In-Group and Out-Group Trust on Conventional and Unconventional Political Participation

ObjectiveThis article explores whether there is a systematic variation in conventional and unconventional political participation as a function of in-group versus out-group trust. We postulate that the narrower the moral community is, the more political participation is restricted to conventional activity that is perceived as an obligation, as a political act to be fulfilled, something akin to cit
