Quarantine hotels have been established by governments to accommodate COVID-19 infected or potentially infectious guests. The employees of these hotels, despite the high-risk environment, must provide services to guests. However, limited research is conducted on the impacts of the pandemic on their psychological well-being and health. This study investigates the protection motivation of quarantine

In this letter, we deal with evolutionary game-theoretic learning processes for population games on networks with dynamically evolving communities. Specifically, we propose a novel mathematical framework in which a deterministic, continuous-time replicator equation on a community network is coupled with a closed dynamic flow process between communities, in turn governed by an environmental feedbac

In this article, we propose a novel solution to detect multiple targets using a distributed multiple-input multiple-output (MIMO) radar under the so-called 'defocused transmit-defocused receive' operating mode. The proposed method employs a grid-based data matching algorithm, aiming to associate the target responses to potential target locations, solving the resulting data puzzle that evaluates th

The stability and activity of a model protein, lysozyme, in 1 : 2 choline chloride : glycerol was characterised across a wide range of protein concentrations, i.e., between 4 and 143 mg ml−1, where the protein is soluble and physically stable. Lysozyme folds into a globular conformation in this deep eutectic solvent like that in the native state, but with subtle variations in its internal structur

Cell-free massive multiple-input multiple-output (MIMO) consists of a large set of distributed access points (APs) serving a number of users. The APs can be far from each other, and they can also have a big number of antennas. Thus, decentralized architectures have to be considered so as to reduce the interconnection bandwidth to a central processing unit (CPU) and make the system scalable. On the

In this work, we describe a new Monte Carlo (MC) simulation method to investigate highly coupled fluids in confined geometries at a constant chemical potential. This method is based on so-called multi-scale Hamiltonian methods, wherein the chemical potential is determined using a more amenable Hamiltonian for a fluid in an "outer"region, which facilitates standard methods, such as grand canonical

Modelling has been a mainstay of conventional planning support tools (PSTs) since the 1960s and is instrumental in transport and land use planning decision-making. Numerous studies have been conducted to model the potential impacts of emerging vehicle automation and sharing technologies. A systematic review of recent modelling studies of autonomous and shared vehicles in the research literature ex

Distributed Acoustic Sensing (DAS) is a recent technology that acquires acoustic vibrations via fiber optics sensors. The utilization of such technique for near-surface geotechnical applications has great potential, especially for the characterization and verification of artificially stabilized ground. A popular procedure to stabilize the superficial ground (for example, for the preparation of inf

Musculoskeletal tissues are complex hierarchical materials where mechanical response is linked to structural and material properties at different dimensional levels. Therefore, high-resolution three-dimensional tomography is very useful for assessing tissue properties at different scales. In particular, Synchrotron Radiation micro-Computed Tomography (SR-microCT) has been used in several applicati

För att att minska städernas koldioxidutsläpp relaterat till val av byggmaterial, byggprocess samt energianvändningen i våra boenden skulle fler hus behöva byggas i trä, renovering i högre grad väljas i stället för rivning, husen skulle behöva göras mer energieffektiva och vi skulle behöva bo fler på mindre yta, menar Johanna Alkan Olsson, docent i miljövetenskap vid Lunds universitet och speciali

Background/Aims Sociodemographic factors are associated with perceived overall health status or ‘self-rated health’. However, research using data from the comprehensive population register in Sweden to examine self-rated health in pregnant women is limited. This study aimed to examine sociodemographic factors associated with self-rated health before, during and after pregnancy in low-risk pregnant

A comprehensive understanding of local HIV epidemiology is essential for monitoring transmission, designing, implementing, and evaluating HIV intervention strategies. In paper I, we used a total of 1276 HIV-1 subtype C pol sequences and employed state-of-art phylogenetic and phylodynamic tools to describe the molecular epidemiology of HIV in Ethiopia. Our results showed that the HIV epidemic in Et

Objectives: The aim of this study was to develop a model that can discriminate between different etiologies of abnormal uterine bleeding. Design: The International Endometrial Tumor Analysis 1 study is a multicenter observational diagnostic study in 18 bleeding clinics in 9 countries. Consecutive women with abnormal vaginal bleeding presenting for ultrasound examination (n = 2,417) were recruited.

Several pathologies related to the atrial electrical activity can be detected in the electrocardiogram P-wave. A study on the beat-to-beat P-wave morphology changes of 89 ECG signals is performed in this article. An algorithm based on the embedding space techniques has been used to extract the P-wave information of the ECG. The P-waves obtained in several of these ECGs exhibit intermittent morphol

Aims: Renal dysfunction in patients with heart failure (HF) has traditionally been attributed to declining cardiac output and renal hypoperfusion. However, other central haemodynamic aberrations may contribute to impaired kidney function. This study assessed the relationship between invasive central haemodynamic measurements from right-heart catheterizations and measured glomerular filtration rate

Permafrost degradation poses serious threats to both natural and human systems through its influence on ecological–hydrological processes, infrastructure stability, and the climate system. The Arctic and the Third Pole (Tibetan Plateau, TP hereafter) are the two northern regions on Earth with the most extensive permafrost areas. However, there is a lack of systematic comparisons of permafrost char

BACKGROUND: The distribution of retroperitoneal lymph node metastases for patients with nonseminoma and a residual tumour of 10-49 mm in a population-based setting is unknown. This information is needed to justify selection of patients for a unilateral template resection. OBJECTIVE: To describe the location of retroperitoneal metastases and recurrences in patients with nonseminoma germ cell tumour

The study of exoplanets and especially their atmospheres can reveal key insights on their evolution by identifying specific atmospheric species. For such atmospheric investigations, high-resolution transmission spectroscopy has shown great success, especially for Jupiter-type planets. Towards the atmospheric characterization of smaller planets, the super-Earth exoplanet 55 Cnc e is one of the most

The vulnerability of gender nonconforming young people is all too well documented. Arguably, “trans issues” in schools are not restricted to transphobic comments, and need to be analyzed intersectionally. Guided by Lugones’ discussion of the politics of purity read together with the analysis of cisnormativity, this article draws on interviews with Rakel, Robin and Mika, who were part of a larger s
