Metabolic tumour volume in Hodgkin lymphoma—A comparison between manual and AI-based analysis
Aim: To compare total metabolic tumour volume (tMTV), calculated using two artificial intelligence (AI)-based tools, with manual segmentation by specialists as the reference. Methods: Forty-eight consecutive Hodgkin lymphoma (HL) patients staged with [18F] fluorodeoxyglucose positron emission tomography/computed tomography were included. The median age was 35 years (range: 7–75), 46% female. The t
ML-Enabled Outdoor User Positioning in 5G NR Systems via Uplink SRS Channel Estimates
Cellular user positioning is a promising service provided by Fifth Generation New Radio (5G NR) networks. Besides, Machine Learning (ML) techniques are foreseen to become an integrated part of 5G NR systems improving radio performance and reducing complexity. In this paper, we investigate ML techniques for positioning using 5G NR fingerprints consisting of uplink channel estimates from the physica
Scheduling for Industrial Control Traffic Using Massive MIMO and Large Intelligent Surfaces
Industry 4.0, with its focus on flexibility and customizability, is pushing in the direction of wireless communication in future smart factories, in particular massive multiple-input multiple-output (MIMO), and its future evolution Large Intelligent Surfaces (LIS), which provide more reliable channel quality than previous technologies. As such, there arises the need to perform efficient scheduling
The Role of Optical Phonon Confinement in the Infrared Dielectric Response of III–V Superlattices
Polar dielectrics are key materials of interest for infrared (IR) nanophotonic applications due to their ability to host phonon-polaritons that allow for low-loss, subdiffractional control of light. The properties of phonon-polaritons are limited by the characteristics of optical phonons, which are nominally fixed for most “bulk” materials. Superlattices composed of alternating atomically thin mat
Lost in translation–production, reproduction and transformation of teacher education knowledge in teacher educators’ local practices
European teacher educations today are expected to not only be ‘close to school practices’, but also to equip their students with academic knowledge. This article analyses one year of fieldwork data to discuss how these expectations are produced, reproduced and transformed in local practices by different categories of teacher educators (lecturers/assistant lecturers). The theory of practice archite
Risky Sexual Behaviour and Sexual Victimization among Young People with Risky Substance Use in Europe-Perspectives from Belgium, Sweden, the Czech Republic, and Germany
BACKGROUND: Research indicates that among the risks associated with young people's alcohol and illicit drug use are sexual risks. However, insights into co-occurrence of substance use and sexual risks in adolescent samples and possible differences across countries are limited. METHODS: A sample of 1449 adolescents from Belgium, Sweden, the Czech Republic, and Germany screened positive for risky al
Superconductivity in monolayer and few-layer graphene. II. Topological edge states and Chern numbers
We study the emergence of electronic edge states in superconducting monolayer, bilayer, and trilayer graphene for both spin-singlet and spin-triplet superconducting order parameters. We focus mostly on the gapped chiral p+ip′- and d+id′-wave superconducting states that show a nonzero Chern number and a corresponding number of edge states. For the p+ip′-wave state, we observe a rich phase diagra
Quantification of growth and nutrient consumption of bacterial and fungal cultures in microfluidic microhabitat models
Understanding microbes in nature requires consideration of their microenvironment. Here, we present a protocol for quantifying biomass and nutrient degradation of bacterial and fungal cultures (Pseudomonas putida and Coprinopsis cinerea, respectively) in microfluidics. We describe steps for mask design and fabrication, master printing, polydimethylsiloxane chip fabrication, and chip inoculation an
Superconductivity in monolayer and few-layer graphene. III. Impurity-induced subgap states and quasiparticle interference patterns
We consider the most energetically favorable symmetry-allowed spin-singlet and spin-triplet superconducting pairing symmetries in monolayer and few-layer graphene and for each calculate the energy spectrum in the presence of a scalar or magnetic impurity. We find that two doubly degenerate subgap states exist for scalar impurities for all types of pairing, except for the spin-singlet s-wave state.
Civil Society Boundary Crossing and Elite Integration
This chapter explores elite boundary crossing between civil society and other societal sectors—including the state, party politics, and business—and how this may lead to inter-elite integration. We illustrate how qualitative life-work history interviews provide an important complement to established quantitative approaches to the study of elite integration. Through these interviews, we explore theThis chapter explores elite boundary crossing between civil society and other societal sectors—including the state, party politics, and business—and how this may lead to inter-elite integration.

Rethinking anthropology in light of ‘Muslim worlds’ : Ephemerality, language and relations in field encounters with transcendence

Angular-dependent interatomic potential for large-scale atomistic simulation of W-Mo-Nb ternary alloys
We present a new classical interatomic potential designed for simulation of the W-Mo-Nb system. The angular-dependent format of the potential allows for reproduction of many important properties of pure metals and complex concentrated alloys with good accuracy. Special attention during the development and validation of the potential was paid to the description of vacancies, screw dislocations and
Conceptualizing Scholar-Activism Through Scholar-Activist Accounts
This chapter delves into one of the ways in which scholars strive to make their work matter, namely, through the practice of scholar-activism. It becomes evident that the concept of scholar-activism is multifaceted and lacks a universally established definition. The objective of this chapter is to gain an insider’s understanding of scholar-activism by exploring its conceptualization and intellectu
Real-world effectiveness of fremanezumab for the preventive treatment of migraine : Interim analysis of the pan-European, prospective, observational, phase 4 PEARL study
Background: The ongoing Pan-European Real Life (PEARL) phase 4 study is evaluating fremanezumab effectiveness and safety for the prevention of episodic and chronic migraine. This interim analysis reports primary, secondary and exploratory endpoints from when 500 participants completed at least six months of treatment. Methods: Adults with episodic migraine or chronic migraine maintaining daily hea

Nordic anal cancer (NOAC) group consensus guidelines for risk-adapted delineation of the elective clinical target volume in anal cancer
Background: To date, anal cancer patients are treated with radiotherapy to similar volumes despite a marked difference in risk profile based on tumor location and stage. A more individualized approach to delineation of the elective clinical target volume (CTVe) could potentially provide better oncological outcomes as well as improved quality of life. The aim of the present work was to establish No
Models and software for corrugated board and box design
To design and develop boxes which protect, and at the same time utilize fiber material efficiently, models and software for predicting corrugated board and box properties are needed. The purpose of this research is to provide propositions toward improving the use and development of models and software for corrugated board and box design. By using an abductive approach, 18 models and four software
