Design and Control of Long-Pulse High-Power Klystron Modulators

The European Spallation Source (ESS) is an under-construction material science research facility in Lund, Sweden, and will upon completion host the most powerful superconducting linear accelerator (linac) in the world. The ESS linac is powered by klystron modulators required to deliver long high-power pulses (pulse amplitude 115 kV/100 A, pulse length 3.5 ms, pulse repetition rate 14 Hz) of very h

Clinical application of flow cytometry in patients with unexplained cytopenia and suspected myelodysplastic syndrome : A report of the European LeukemiaNet International MDS-Flow Cytometry Working Group

This article discusses the rationale for inclusion of flow cytometry (FCM) in the diagnostic investigation and evaluation of cytopenias of uncertain origin and suspected myelodysplastic syndromes (MDS) by the European LeukemiaNet international MDS Flow Working Group (ELN iMDS Flow WG). The WHO 2016 classification recognizes that FCM contributes to the diagnosis of MDS and may be useful for prognos

The contest between internal and external-beam dosimetry : The Zeno's paradox of Achilles and the tortoise

Radionuclide therapy, also called molecular radiotherapy (MRT), has come of age, with several novel radiopharmaceuticals being approved for clinical use or under development in the last decade. External beam radiotherapy (EBRT) is a well-established treatment modality, with about half of all oncologic patients expected to receive at least one external radiation treatment over their disease course.

Cryo-EM structure of the trehalose monomycolate transporter, MmpL3, reconstituted into peptidiscs

Mycobacteria have an atypical thick and waxy cell wall. One of the major building blocks of such mycomembrane is trehalose monomycolate (TMM). TMM is a mycolic acid ester of trehalose that possesses long acyl chains with up to 90 carbon atoms. TMM represents an essential component of mycobacteria and is synthesized in the cytoplasm, and then flipped over the plasma membrane by a specific transport

Arthroscopic partial meniscectomy for the degenerative meniscus tear : a comparison of patients included in RCTs and prospective cohort studies

Background and purpose — Concerns exist regarding the generalizability of results from randomized controlled trials (RCTs) evaluating arthroscopic partial meniscectomy (APM) to treat degenerative meniscus tears. It has been suggested that study populations are not representative of subjects selected for surgery in daily clinical practice. There-fore, we aimed to compare patients included in trials

Gene amplification in neoplasia : A cytogenetic survey of 80 131 cases

Gene amplification is a crucial process in cancer development, leading to the overexpression of oncogenes. It manifests cytogenetically as extrachromosomal double minutes (dmin), homogeneously staining regions (hsr), or ring chromosomes (r). This study investigates the prevalence and distribution of these amplification markers in a survey of 80 131 neoplasms spanning hematologic disorders, and ben

Reference standards for gene fusion molecular assays on cytological samples : an international validation study

Aims Gene fusions assays are key for personalised treatments of advanced human cancers. Their implementation on cytological material requires a preliminary validation that may make use of cell line slides mimicking cytological samples. In this international multi-institutional study, gene fusion reference standards were developed and validated. Methods Cell lines harbouring EML4(13)–ALK(20) and SL

Occupational performance problems in people with depression and anxiety

Background: Depression and anxiety often reduce people’s ability to cope with everyday occupations. There is a lack of knowledge about such problems in people of working age with depression and anxiety. Aim: To describe which problems people with depression or anxiety disorders experience when performing everyday occupations and which occupations are affected. Materials and methods: Data based on

The flexible assertive community treatment fidelity scale : description of the development in the Netherlands and adaptation in Denmark and Sweden

Assertive Community Treatment (ACT) is the most common ambulatory service delivery model for people with severe mental illness worldwide. Flexible ACT, a Dutch modification of ACT, provides comprehensive care for the entire population of people with severe mental illness (SMI). FACT combines the principles of individual case management with ACT services. Researchers found an association between mo

Red cell distribution width and its polygenic score in relation to mortality and cardiometabolic outcomes

Introduction: Elevated red cell distribution width (RDW) has been associated with a range of health outcomes. This study aims to examine prognostic and etiological roles of RDW levels, both phenotypic and genetic predisposition, in predicting cardiovascular outcomes, diabetes, chronic kidney disease (CKD) and mortality. Methods: We studied 27,141 middle-aged adults from the Malmö Diet and Cancer s

The management of lupus nephritis as proposed by EULAR/ERA 2019 versus KDIGO 2021

In 2019 and 2021, the European League for Rheumatism (EULAR) jointly with the European Renal Association (ERA) and the Kidney Disease: Improving Global Outcomes (KDIGO), respectively, released updated guidelines on the management of lupus nephritis (LN). The Immunology Working Group of the ERA reviewed and compared both updates. Recommendations were either consistent or differences were of negligi

Dynamic Drivers for Building Carbon Emissions

Carbon emissions from buildings have inherently dynamic characteristics since buildings evolve over time. Most previous studies, however, implemented static building carbon regimes, ignoring the temporal variation of many factors that govern carbon emissions of buildings. This research explores the influences of four dynamic factors acting on building carbon emissions: dynamic climate change data,

RESISTING WHILST COMPLYING? A CASE STUDY OF A POWER STRUGGLE IN A BUSINESS SCHOOL

Business school faculty are frequently faced with management practices they find objectionable. Reactions vary, but compliance and hidden resistance are common responses. In this paper, we seek to understand compliance and hidden resistance as responses to objectionable management practices in business schools. To explore this problem, we present a case study of a business school where a new dean

Mechanical integrity of PVD TiAlN-coated PcBN : Influence of substrate bias voltage and microstructural assemblage

Polycrystalline cubic boron nitrides (PcBN) have been increasingly used together with PVD coatings, mainly for hard turning operations. Within this context, effectiveness of coated PcBN as cutting tool is usually addressed by evaluation of its machining performance. Meanwhile, studies aiming to assess and understand the correlation between microstructural features and mechanical behaviour of the c

Student Notetaking Media in Higher Education

This paper explores the evolution of research methodology in the study of student notetaking in higher education (HE) and its impact on pedagogic approaches. While acknowledging the importance of notetaking for student learning, the paper argues that the overreliance of randomized control trials (RCTs) has led to some potentially misleading conclusions about lectures in HE and the notes students m
