A Survey on Channel Sounding Technologies and Measurements for UAV-Assisted Communications

Unmanned aerial vehicles (UAVs) have been widely used in both military and civilian applications, where a stable communication link is vital for safe flight control and robust data transmission. To develop a reliable UAV communication system, it is necessary to deeply understand the UAV channel characteristics and establish accurate channel models. Channel sounding is the most effective way to obt

Med det förflutna för ögonen

At a retirement it is natural to have the past in front of you, in particular as a historian. But contrary to what we normally think – that we have the past behind us and the future in front of us – all of us in reality look at the future through the past. What we see is not what will happen but what has happened, and, moreover, as interpreted by our experiences of what has happened earlier. The p

Selection on the joint actions of pairs leads to divergent adaptation and coadaptation of care-giving parents during pre-hatching care

The joint actions of animals in partnerships or social groups evolve under both natural selection from the wider environment and social selection imposed by other members of the pair or group. We used experimental evolution to investigate how jointly expressed actions evolve upon exposure to a new environmental challenge. Our work focused on the evolution of carrion nest preparation by pairs of bu

Lightweight vehicles in indirect structural health monitoring : Current advances and future prospects

Recent research has explored the potential of using the dynamic response of passing vehicles to conduct Structural Health Monitoring (SHM) efficiently. Various types of vehicles, including cars, vans, trucks, and even manually propelled carts, have been employed in this approach, with different configurations of exciters and receivers. A noteworthy development in this field involves the inclusion

Progress of vegetation modelling and future research prospects

Terrestrial vegetation is a crucial component of the Earth system, and its changes not only represent one of the most distinct aspects of climate change but also exert significant feedback within the climate system by exchanging energy, moisture, and carbon dioxide. To quantitatively and mechanistically study climate-vegetation feedback, numerical vegetation models have been developed on the theor

Sociodemographic Inequalities in Student Achievement : An Intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA)

Sociodemographic inequalities in student achievement are a persistent concern for education systems and are increasingly recognized to be intersectional. Intersectionality considers the multidimensional nature of disadvantage, appreciating the interlocking social determinants which shape individual experience. Intersectional multilevel analysis of individual heterogeneity and discriminatory accura

Blood Pressure Regulation in Post–COVID POTS : Beyond Sinus Tachycardia

BACKGROUND:Postural orthostatic tachycardia syndrome (POTS) is a frequently diagnosed cardiovascular disorder after COVID-19 infection. POTS is characterized by the presence of excessive sinus tachycardia on standing without a fall in blood pressure (BP). We investigated the BP profile using 24-hour ambulatory BP monitoring in patients with new-onset POTS after COVID-19 compared with prepandemic p

Preliminary evaluation of an automated autoencoder-UNet pipeline for chemical image segmentation and compression with reference to serial ground truth pathology

The rapid advancement of imaging technologies in pathology has ushered in an era of data-intensive diagnostic workflows, generating large volumes of data that demand sophisticated segmentation and compression techniques. Chemical imaging approaches offer an all-digital objective approach to pathological analysis, though image segmentation is required for efficient computation. Convolutional autoen

Genomic identification of expressed globulin storage proteins in oat

Introduction: Oats, a highly nutritious cereal known for their health benefits, contain various macromolecules of significant biological value, including abundant and highly digestible proteins. Despite their importance, oat proteins have not been extensively studied. Here, we present a complete set of the expressed globulins genes, which code for the main storage protein in oats as well as their

Management of Reflex Syncope : Non-Pharmacological and Pharmacological

Non-pharmacological interventions represent the first-line treatment approach for patients with non-cardiac syncope. These interventions include reassurance of the benign nature of syncope, education about triggers and strategies to avoid them, early recognition of prodromal symptoms, and lifestyle measures to counteract blood pressure falls. Adequate water intake is recommended to avoid hypovolem

The Donovan–Wemyss Conjecture via the Derived Auslander–Iyama Correspondence

We provide an outline of the proof of the Donovan–Wemyss Conjecture in the context of the Homological Minimal Model Program for threefolds. The proof relies on results of August, of Hua and the second-named author, Wemyss, and on the Derived Auslander–Iyama Correspondence—a recent result by the first- and third-named authors.

‘Fighting for our people’: femininity and violence in portrayals of women who use drones in Ukraine

Men outnumber women as military drone operators, both in media narratives and in reality, as prominent Western militaries such as the US and the UK have far more men than women in their ranks. In recent years, Russia’s invasion of Ukraine has brought newfound attention to the use of drone warfare; specifically, how the media overwhelming spotlights male drone operators. However, portrayals of wome

Responders to first-line osteoarthritis treatment had reduced frequency of hip and knee joint replacements within 5 years : an observational register-based study of 44,311 patients

Background and purpose — First-line treatment (education, exercise) for patients with hip and knee osteoarthritis (OA) aims to reduce pain and improve function. We aimed to compare progression to joint replacement within 5 years between responders and non-responders to first-line treatment for hip and knee OA, respectively. Methods — This observational study included data for 30,524 knee OA and 13

MICRO-GEOGRAPHIES OF ADMINISTRATION : A WOLF IN SHEEP’S CLOTHING? THE IMPACT OF TRUST ON A STREET-LEVEL APPROACH TO IMMIGRANT INTEGRATION

Increased global migration to welfare states puts pressure on successful integration. Successful integration is broadly associated with entry into the labour market. Therefore, integration is measured through employment. Attempts to increase migrant involvement in the labour market are often made by street-level organisations, where interactions between individuals from the private and/or public s

Rejecting norms of standing for private blame

We argue that we should be sceptical towards the claim that there is such a thing as the standing to blame someone privately, understood in terms of holding the attitude of blame. Key features of the idea about standing to blame do not apply to private blame. For example, we argue that private blame is not the exercise of some normative power, and it is not even pro tanto wrong for a hypocrite to

Ambulance Travel Time Estimation using Spatiotemporal Data

Ambulance travel time estimations play a pivotal role in ensuring timely and efficient emergency medical care by predicting the duration for an ambulance to reach a specific location. Overlooking factors such as local traffic situations, day of the week, hour of the day, or the weather may create a risk of inaccurately estimating the ambulance travel times, which might lead to delayed emergency re

Effectiveness of R-CHOP versus R-CHOEP for treatment of young patients with high-risk diffuse large B-cell lymphoma : A Danish observational population-based study

Purpose: Etoposide to standard R-CHOP is used for high-risk diffuse large B-cell lymphoma (DLBCL) in some countries. Due to the lack of randomized trials, a real-world data study using matching methods was used to test the potential effectiveness of R-CHOEP over R-CHOP. Patients and Methods: This study included patients from the Danish Lymphoma Register diagnosed between 2006 and 2020 at the age o
