Sub-THz frequencies are tomorrow's hot research area in mobile communication. However, in this range of frequencies the systems are complex, and it is hard to explore various system architectures and correlate the system-level solutions with circuit-level performances and requirements. This paper presents a scalable testbench in MATLAB/Simulink for sub-THz hybrid beamforming receivers. The testben
Globally, there is a widespread consensus that the transition to circular economy (CE) within the construction industry represents a crucial pathway to achieve the decarbonization of the industry by 2050 while fostering economic growth. At the European level, policies and legislations are progressively promoting the use of circular building products and encouraging higher levels of energy and reso
Background: Despite newer treatments with immunosuppressive agents, there still exists a considerable morbidity and mortality risk among patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Since 1994 the European Vasculitis Society (EUVAS) has aimed for an improved outcome for patients with AAV, conducting several prospective randomized controlled trials (RCTs).
Earth's life support systems depend on biodiversity and healthy ecosystems. Without radical transformations, staying within safe planetary boundaries becomes impossible. While the inequalities between Global North and Global South are increasingly acknowledged, the agency and rights of people often placed in the category of 'vulnerable' -women, youth, indigenous peoples and local communities- are
This paper discusses Netsourcing strategies for vendors, a little explored area of outsourcing research, using both a resource-based (RBV) perspective and a transaction cost economics (TCE) perspective. Using both theories and an infrastructural view of Information Technology service, we present a conceptual model of vendor sourcing decisions. We then present a number of propositions based on case
Petrochemical producers both rely upon and generate some of the most problematic substances in the current age of socioecological crisis: fossil fuels and plastics. With mounting calls to cap fossil fuel extraction as well as plastics production, the industry appears to be caught between a rock and a hard place. Nonetheless, betting on continuously increasing global plastic demand, petrochemical p
We present a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized. The method is based on fabrication of high aspect ratio silicon microstructures using deep reactive ion etching (Bosch technique) of dense grating arrays and followed by conformal electroplating
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-field tomography exploits scattering to probe sub-resolution features, promising to overcome this trade-off. In this work, we present a quantific
Metal microstructured optical elements for grating-based X-ray phase-contrast interferometry were fabricated by using an innovative approach of microcasting: hot embossing technology with low melting temperature (280 °C) metal alloy foils and silicon etched templates. A gold-tin alloy (80 wt% Au/20 wt% Sn) was used to cast micro-gratings with pitch sizes in the range of 2 to20 μm and depth of the
Digital practices in later life are not yet well understood. Therefore, this paper discusses the framework for a research design project that aims at tracing differences and similarities in how older adults use their smartphones in circumstances in and outside their homes in Spain, the Netherlands, Sweden, and Canada. The research questions of this international research project focus on the exten
Glucagon-like peptide 1 receptor agonist exenatide (exendin-4) has potential protective capabilities against diabetic kidney disease (DKD). However, the underlying mechanism has not been fully elucidated. The expression of thioredoxin-interacting protein (Txnip) is upregulated during DKD progression by histone acetylation. Sirtuin 1 (SIRT1) is a deacetylase and is decreased in DKD, which indicates
Importance: Despite some promising preclinical and clinical data, it remains uncertain whether remote ischemic conditioning (RIC) with transient cycles of limb ischemia and reperfusion is an effective treatment for acute stroke. Objective: To evaluate the effect of RIC when initiated in the prehospital setting and continued in the hospital on functional outcome in patients with acute stroke. Desig
Background: Despite improvements in hemophilia care, challenges remain, including treatment burden and impaired quality of life. Gene therapy may overcome these. However, its introduction presents a challenge. Objectives: To outline a function-based gene therapy working model describing critical milestones associated with gene therapy handling, administration, and follow-up to facilitate and imple
The classical model selection criteria, such as the Bayesian Information Criterion (BIC) or Akaike information criterion (AIC), have a strong tendency to overestimate the number of regressors when the search is performed over a large number of potential explanatory variables. To handle the problem of the overestimation, several modifications of the BIC have been proposed. These versions rely on su
One example of a PET exam that suffers from noise problems is [68Ga]Ga-DOTA-TOC, where patients are generally administered between 100 and 200 MBq [68Ga]Ga-DOTA-TOC, irrespective of size. However, a fixed activity can result in low signal-to-noise ratios (SNRs) in larger patients. This study aimed to evaluate the impact on image quality with respect to injected activity and patient habitus through
Background: Information and communication technology (ICT) provides one solution to meet increasing demands for occupational therapy for older adults. Aims/Objectives: To examine if and how municipality-based occupational therapists (OTs) include ICT in their work, and which factors are associated with use of occupational therapy at a distance. Material and Methods: Survey study including 167 OTs.
In the field of sociophysics, concepts and techniques taken from statistical physics are used to model and investigate some social and political behavior of a large group of humans: their social network is given by a simple graph and neighboring individuals meet and interact in pairs or small groups. Although most of the established models feature rather simple microscopic interaction rules, the m
In ‘Alfred Nobel’s Karlskoga’, Sweden, the municipality has placed its most famous former resident at the heart of its economic development strategy. Through an in-depth qualitative case study, we examine the tensions and complexities surrounding this process and fill an existing research gap around personality-based place branding for regional development purposes. The findings suggest that even
