Primordial black holes formed through the collapse of cosmological density fluctuations have been hypothesized as contributors to the dark matter content of the Universe. At the same time, their mergers could contribute to the recently observed population of gravitational-wave sources. We investigate the scenario in which primordial black holes form binaries at late times in the Universe. Specific
Purpose: The purpose of this paper is to review the Russian Federation Government Quality Award (RFGQA) over its 25-year existence. Design/methodology/approach: This paper looks into the evolution, model and key provisions of RFGQA, based on the authors’ long-time experience as an Award assessor. Apart from that, methodologically, this study uses the desktop research method, comparative literature
Data-independent acquisition-mass spectrometry (DIA-MS) is the method of choice for deep, consistent, and accurate single-shot profiling in bottom-up proteomics. While classic workflows for targeted quantification from DIA-MS data require auxiliary data-dependent acquisition (DDA) MS analysis of subject samples to derive prior-knowledge spectral libraries, library-free approaches based on in silic
Free electron lasers or FELs, have transformed the way science has been done in the last decades by providing coherent, highly brilliant radiation at wavelengths not achievable with conventional lasers. Their most important characteristic, along side brightness, is their coherence, which allows users to perform experiments that rely on precise phase characteristics of the probing radiation.The FEL
Smartphones have become one of the main tools for travel information search, especially on site, during the trip. The use of mobile technologies and ubiquitous internet connectivity do not only allow tourists to access information anywhere, at any time, but have deep impacts on tourists’ behaviours and on their whole tourist experience.The study suggests an interpretation of tourists’ information
Scarce water resources present a major hindrance to ensuring food security. Crop water productivity (WP), embraced as one of the Sustainable Development Goals (SDGs), is playing an integral role in the performance-based evaluation of agricultural systems and securing sustainable food production. This study aims at developing a cloud-based model within the Google Earth Engine (GEE) based on Landsat
BACKGROUND: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers.AIMS: In an 11-week intervention programme, speech-language therapists (SLTs) presented the participating teachers with whole-class teaching techniques aimed at creating a language and communication-supporting classro
BACKGROUND: The long-term outcome after local excision of T1 colorectal cancer (CRC) remains unknown. The aim of this study was to examine clinical and histopathological risk factors for recurrence in patients with T1 CRC undergoing endoscopic resection.METHODS: This was a retrospective registry-based population study on prospectively collected data of all patients with nonpedunculated T1 CRC unde
Low- and middle-income countries (LMICs) are significantly affected by SARS-CoV-2, partially due to their limited capacity for local production and implementation of molecular testing. Here, we provide detailed methods and validation of a molecular toolkit that can be readily produced and deployed using laboratory equipment available in LMICs. Our results show that lab-scale production of enzymes
OBJECTIVE: To report the mid-term outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) following a failed previous endovascular aneurysm repair (pEVAR) or previous open aneurysm repair (pOAR).METHODS: Data from consecutive patients who underwent F-BEVAR for pEVAR or pOAR from 2006-2021 from 17 European vascular centres were analyzed. Endpoints included technical success, major a
In this paper we look at the adaption of SI-PASS programmes during the COVID-19 pandemic drawing from four Higher Education Institutions (HEIs) as case studies: The National University of Ireland (NUI) Galway in Ireland, Nord University in Norway, Lund University in Sweden and the University of Manchester in the UK. The paper also focuses on the role of SI-PASS in student engagement in an extraord
Warming in the Arctic accelerates thawing of permafrost-affected soils, which leads to a release of greenhouse gases to the atmosphere. We do not know whether permafrost thaw also releases non-methane volatile organic compounds that can contribute to both negative and positive radiative forcing on climate. Here we show using proton transfer reaction–time of flight–mass spectrometry that substantia
Since the 1990s, social work has been subject to requirements for monitoring and quality assurance. Here we examine one of the monitoring systems: Open Comparisons (OC). Gradually expanded and published online by a national agency, the OC now has around 350 indicators that cover major areas within social work in Sweden. We use program theory to clarify the operational idea in which OC is based. To
Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people’s answers are not very consistent and represent statements without any strong b
Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long-term land cover-climate feedbacks. Observation-based reconstructions of past land cover are rare, and commonly used model-based reconstructions exhibit considerable differences. Recently, Pirzamanbein et al. (2018, 10.1016/j.spasta.2018.03.005, Spati
Over the last few decades, the African Sahel has become thefocus of many studies regarding vegetation dynamics and theirrelationships with climate and people. This is because rainfalllimits the production of biomass in the region, a resource onwhich people are directly dependent for their livelihoods. In thisstudy, we utilized a remote-sensing approach to answering thefollowing two questions: (1)
Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were co
Many industries, which are producing sludge in large quantities, depend on sludge dewatering technology to reduce the corresponding water content. A key design parameter for dewatering equipment is the capillary suction time (CST) test, which has, however, several scientific flaws, despite that the test is practical and easy-to-perform. The standard CST test has a few considerable drawbacks: its l
BACKGROUND: Axillary staging via sentinel lymph node biopsy (SLNB) is performed for clinically node-negative (N0) breast cancer patients. The Skåne University Hospital (SUS) nomogram was developed to assess the possibility of omitting SLNB for patients with a low risk of nodal metastasis. Area under the receiver operating characteristic curve (AUC) was 0.74. The aim was to validate the SUS nomogra
INTRODUCTION: The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA).METHOD: A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years p
