This paper investigates the wideband channel characteristics obtained in a classroom and a hall indoor scenarios at 2-4, 9-11 and 27-29GHz. A virtual uniform circular array (UCA) based channel sounding system was utilized to capture wideband spatial channel characteristics. The propagation parameters of multipath components (MPCs) were estimated by using a high resolution parameter estimation (HRP

This paper presents the numerical study of soot formation and oxidation processes across different ambient temperatures (900K, 1000K, and 1100K) and oxygen levels (15% and 21% O2) using large eddy simulation coupled with a two-equation soot model. The predicted ignition delay time, lift-off length and soot distribution show good agreements with the corresponding experimental data. A stronger oxida

Opening remarks – These guidelines are the result of dis-cussions within a diverse group of RSA researchers. They were approved in December 2023 by the board and selected members of the International Radiostereometry Society to update the guidelines by Valstar et al. [1]. By adhering to these guidelines, RSA studies will become more transparent and consistent in execution, presentation, reporting,

Sagarmatha (Everest) has long been recognised as one of the principal goals of global adventure tourism. Supported by high-altitude workers, paying climbers on Sagarmatha have the opportunity to tread in the footsteps of colonial pioneers such as George Mallory and Sir Edmund Hillary. Ever since the first attempt was made to summit Sagarmatha there has been an appreciation amongst the climbing com

Non-metropolitan regions are considered more exposed to external shocks than their metropolitan counterparts, while having lower capacities to change. However, there is considerable variation among non-metropolitan regions. We argue that this variation can be captured theoretically by modelling the dynamic interplay between perceived and real opportunity spaces and agency. We empirically analyse r

This article provides a comprehensive overview of digital technologies for water use and management in agriculture, examining recent applications and future prospects. It examines key water-related challenges - scarcity, pollution, inefficient use and climate change - and shows how various digital technologies such as Remote Sensing, Artificial Intelligence, the Internet of Things, Big Data, Robot

The article intends to show: a) that the modist Martin of Dacia sides with the traditional reading of the first chapter of Aristotle's De interpretatione that we find in masters of arts from the first half of the thirteenth century; and b) that the modist Boethius of Dacia is one of the first thirteenth-century scholars to depart from this reading. In fact, Boethius presents us with an account of

We explore the determinants of term premiums and evaluate the influence of the US market on term premiums in seven developed countries. Our analysis shows that poor economic conditions and high uncertainty lead to increased term premiums. Further, our results highlight the importance of US economic conditions and uncertainty factors as well as the supply of US government bonds as key drivers of in

Drug-resistant bacterial infections are among the most severe physiological challenges facing human health. Therefore, the detection and inactivation of pathogenic bacteria remains a crucial therapeutic goal in modern society. In this study, we design multifunctional nanocomposites aimed at bacterial binding, fluorescence labeling, and synergistic antibacterial treatment. These nanocomposites are

Depressive and anxiety disorders are leading causes of disability globally. Therapist-guided, Internet-delivered cognitive behaviour therapy (ICBT) is an established treatment for depression and anxiety, but a considerable proportion of treated patients do not achieve sufficient improvement. Predicting symptom changes based solely on clinical variables is challenging, and genetic data could offer

Purpose: Abdominal wall complications can be reduced by adhering to guidelines for midline laparotomy closure. However, implementation of guidelines can be challenging. To address this issue, a laparotomy closure device for swift and standardized abdominal closure was developed. The study evaluated the quality of the suture, safety, and speed of the device in a clinical setting. Methods: A prospec

För att främja ett aktivt och hälsosamt åldrande (AHA) är det avgörande att förstå hur olika generationer använder digitala teknologier, då dessa verktyg blir en alltmer integrerad del av vardagen. Detta avhandlingsprojekt undersökte teknikanvändning bland kvinnor och män i tre åldersgrupper som representerar olika generationer (30–39, 50–59 och 70–79 år), med fokus på attityder, användningsmönsteTo promote active and healthy ageing (AHA), it is essential to understand how different generations engage with digital technologies, as these tools are becoming increasingly integral to everyday life. This thesis project explored technology adoption among men and women from three age groups representing different generations (30–39, 50–59 and 70–79 years), focusing on attitudes, usage patterns, a

The metalorganic chemical vapor deposition (MOCVD) dynamics of beta-gallium oxide (β-Ga2O3) growth using trimethylgallium (TMGa) and oxygen as precursors were investigated through both theoretical thermodynamic analysis and experimental validation in a horizontal low-pressure hot-wall reactor. Thermodynamic analysis revealed that high-purity β-Ga2O3 can be grown through the complete combustion of

Gamified virtual reality (VR) environments are increasingly used to enhance engagement and learning, yet most designs still adopt a one-size-fits-all approach that overlooks motivational diversity. The HEXAD framework, which classifies users into six player types, provides a promising lens for addressing this gap, but its predictive validity in immersive VR remains contested. This study investigat

A search for the resonant production of a heavy scalar X decaying into a Higgs boson and a new lighter scalar S, through the process X → S(→bb¯)H(→γγ), where the two photons are consistent with the Higgs boson decay, is performed. The search is conducted using an integrated luminosity of 140 fb−1 of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector
