We study the influence of tree's depth and nodes' fan-out on the performance of WiMax mesh networks. For a given tree topology, we first analytically obtain per-node delay and per-node throughput. Then among plenty of tree topologies, extractable from a given network's graph, we search feasible trees which fulfil some per-node and network QoS requirements. Since the searching space is potentially
Background and aims: Obesity is on the rise globally, and is a leading risk factor for T2D. However, it is very heterogeneous, with varying degrees of T2D risk within the same levels of BMI. Better classification may lead to improve outcomes of current preventive and therapeutic strategies. Moreover, by elucidating the mechanisms uncoupling obesity from T2D risk, new possible therapeutic targets m
This chapter aims to provide practical evidence-based guidance in the use of generative artificial intelligence (GenAI) for the design and management of authentic assessment tasks and provide a grounding for institutional policy conversations so that decisions can be influenced in a constructive learner-centric way. Drawing on the foundational principles of assessment and feedback, we critically e
Den ökade digitaliseringen av ekonomin har medfört betydande utmaningar för traditionella skattesystem, särskilt i fråga om beskattning av multinationella företag med omfattande digital närvaro men utan fysisk etablering. Detta har lett till rättvisa konkurrensförhållanden mellan den digitala och den traditionella marknaden samt mellan olika staters skattebaser. Mot denna bakgrund har digital beskThe increasing digitalisation of the economy has led to significant challenges to traditional tax systems, particularly with regard to the taxation of multinational enterprises with substantial digital presence but no physical establishment. This has led to unequal competitive conditions between the digital and traditional markets, as well as between different states’ tax bases. Against this backg
Agricultural commercialization is concerned with improving market-oriented production in expectation of maximizing profit. While previous state policies in Ghana favoured commercialization by medium and large scale cultivators, there exists a new national commitment dubbed the Planting for Food and Jobs Policy that seeks to leverage on the cumulative productive potential of small farmers for susta
Dyspnea and chest pain are major and important causes of contact at the emergency department (ED). Dyspnea is associated with high morbidity and mortality, but data on characteristics and outcomes compared with chest pain in the ED are limited. This was a retrospective cohort study of consecutive patients with contact causes of dyspnea or chest pain at two Swedish EDs from 2010 to 2014. Hospital a
The present study aims to describe accelerometer-assessed physical activity (PA) patterns and fulfillment of PA recommendations in a large sample of middle-aged men and women, and to study differences between subgroups of socio-demographic, socio-economic, and lifestyle-related variables. A total of 27 890 (92.5% of total participants, 52% women, aged 50–64 years) middle-aged men and women with at
Organizational ambidexterity has emerged as a research area promoting innovation for both short- and long- term success. Structural ambidexterity proposes dual structures and strategies to differentiate efforts, focusing on one or the other form of innovation. In contrast, contextual ambidexterity relies on behavioral and social means to integrate exploitation and exploration. In this article we h
Although deep neural networks (DNNs) are high-performance methods for various complex tasks, e.g., environment perception in automated vehicles (AVs), they are vulnerable to adversarial perturbations. Recent works have proven the existence of universal adversarial perturbations (UAPs), which, when added to most images, destroy the output of the respective perception function. Existing attack metho
OBJECTIVES: To evaluate the health-related quality of life (HRQL) of patients with head and neck cancer during and after treatment with radiotherapy, surgery, and chemotherapy. STUDY DESIGN: Prospective, descriptive study. METHODS: All new patients in four institutions in Norway and Sweden were asked to participate. Health-related quality of life was assessed at baseline and at 1, 2, 3, 6, and 12
Popular Abstract in Swedish Hållbar utveckling ställer krav på nya riskanalysmetoder Hållbar utveckling bygger på vår förmåga att fatta beslut i dag som avgör vår morgondag. Det låter enkelt, men är en av mänsklighetens största utmaningar då mycket i vår värld hänger samman och framtiden är full av osäkerheter. Givet att osäkerhet tillåts påverka vår syn på vad framtiden har i sitt sköte, kan dSustainable development relies on our ability to make decisions today that will determine our tomorrow. Given that uncertainty is explicitly allowed to influence our view of what the future holds for us, most ex ante analyses of challenges for sustainable development can be viewed as analysing risk. Many frameworks for analysing risk exist today, but analysing risk for sustainable development enta
Macroeconomic fluctuations affect corporations’ performance through demand and cost conditions. Incentive effects of performance-based compensation schemes for management may be weakened or biased by macroeconomic influences if management is unable to forecast macroeconomic fluctuations or unable to adjust operations in response to changes in macroeconomic conditions. In this paper we analyze the
Vad är en kompetensportfölj? En samling arbetsprover som visar upp den egna kompetensen? En elektronisk plattform för dokumentlagring? En övning i reflektion och utveckling? I denna rapport samlas erfarenheter från medarbetare vid Lunds universitet som under perioden 2015–2016 har arbetat med kompetensportföljer – för studenter och lärare. Rapporten redovisar resultat från tre delprojekt: • Utveck
