Reconfigurable intelligent surface (RIS) can manipulate the electromagnetic (EM) waves in wireless channels and thus is promising for the sixth generation wireless communication systems. However, there exists little research on RIS channel measurements, which are important for the communication system design. In this paper, channel measurements are carried out in anechoic chamber, outdoor, and ind
This paper presents an experimental study on the joint effects of concurrent airflow and sample width on the steady flame spread behaviors. Flame spread parameters, including flame height, preheating length, heat flux distribution, flame spread rate (FSR) and pyrolysis length, were measured and analyzed comprehensively. Results show that the FSR and pyrolysis length increase with sample width and
Background: There is variability in the use of sedatives and analgesics in neonatal intensive care units (NICUs). We aimed to investigate the use of analgesics and sedatives and the management of neonatal pain and distress. Methods: This was a global, prospective, cross-sectional study. A survey was distributed May–November 2022. The primary outcome of this research was to compare results between
Respiratory symptoms are ubiquitous and impair health-related quality of life in people with respiratory disease. This European Respiratory Society (ERS) task force aimed to provide recommendations for symptomatic treatment in people with serious respiratory illness. The ERS task force comprised 16 members, including representatives of people with serious respiratory illness and informal caregiver
The Sensory Processing Measure, second edition (SPM-2), is an American assessment guiding person-centered sensory processing interventions, but it lacks Swedish adaptation for occupational therapists. In eight phases, this study translated the SPM-2 into Swedish and assessed its face validity and preliminary psychometric properties, including internal consistency and inter-scale/item correlations.
Aiming for the sixth generation (6G) wireless communications, distributed massive multiple-input multiple-output (MIMO) systems hold significant potential for spatial multiplexing. In order to evaluate the ability of a distributed massive MIMO system to spatially separate closely spaced users, this paper presents an indoor channel measurement campaign. The measurements are carried out at a carrier
Social exclusion and individuals’ self-sufficiency have been on the public agenda in Sweden recently. One reason is the large influx of immigrants to Sweden in 2016. This paper aims to measure self-sufficiency over time, across the life cycle, depending on geographical origin, and time spent in Sweden to provide information about how self-sufficiency has developed over time and across the life cyc
Battery-free IoT devices are becoming increasingly interesting for environmental and practical reasons, with ambient backscatter as one of the candidate technologies. We present a class of balanced transmission patterns for ambient backscatter communication (BSC) and evaluate their performance under different signal-to-interference ratios and fading conditions. These patterns allow for bit synchro
Prostate Cancer Diagnosis and Treatment Enhancement through the Power of Big Data in Europe (PIONEER) is a European network of excellence for big data in prostate cancer. PIONEER brings together 34 private and public stakeholders from 9 countries in one multidisciplinary research consortium with the aim of positively transforming the field of prostate cancer clinical care by answering pressing que
Outcome under-ascertainment, characterized by the incomplete identification or reporting of cases, poses a substantial challenge in epidemiologic research. While capture-recapture methods can estimate unknown case numbers, their role in estimating exposure effects in observational studies is not well established. This paper presents an ascertainment probability weighting framework that integrates
Bees are essential pollinators of many crops and wild plants, and pesticide exposure is one of the key environmental stressors affecting their health in anthropogenically modified landscapes. Until recently, almost all information on routes and impacts of pesticide exposure came from honey bees, at least partially because they were the only model species required for environmental risk assessments
This article employs a holistic understanding of environmental, social, and economic sustainability to explore the interaction between neoliberalism, climate crisis, digitalization, and academic work with a focus on its everyday aspects. Drawing our experience of organizing an online conference during the Covid-19 pandemic and our dialogue with conference participants, we first problematize the pr
Testing printed circuit boards (PCBs) is an important part of the production process. The development and generation of tests is however a labour-intensive process that requires expertise and deep understanding of the PCB. As generative Artificial Intelligence in form of Large Language Models (LLMs) as evolved, we explore its use for PCBs test generation. The main question is: for a given design s
Diffusion weighted magnetic resonance imaging (DW-MRI) technique probing the microscopic movement of water molecules in tissue, allows for the quantification of water diffusivity and the contribution of perfusion to the total amount of water. In the last decades, its use in organs other than the brain has increased and it has successfully been applied to abdominal organs; otherwise the use of DWI
This paper proposes an alternative semi-analytical Fourier modal method adapted for general periodic anisotropic gratings made of dielectrics with moderate to low index profiles corresponding to materials ranging from conventional dielectric 3D printing materials to ceramic materials. The proposed method is closely related to classical Rigorous Coupled-Wave Analysis built on scattering matrices, h
Current policy approaches addressing climate change have been insufficient. Integrative approaches linking inner and outer factors of behavior change, both at the private and organizational level, have been called for. The aim of the present study was thus to conceptualize and test a model of interlinkages between trainable transformative psychological qualities, meditation practice, wellbeing, st
The study of public transport and tourism, especially domestic tourism, is relatively under-researched, particularly in relation to emerging transport technologies, such as artificial intelligence (AI), and environmental, social, and governance (ESG). To bridge this gap, an integrated research model is created and tested with ESG, air quality, climate change, and AI, applying multi-analysis method
