A search is conducted for a new scalar boson S, with a mass distinct from that of the Higgs boson, decaying promptly into four leptons (ℓ=e, μ) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons Zd: S→ZdZd→4ℓ, where the Zd boson has a mass between 15 and 300 GeV, and the S boson has a mass between either 30 and 115 GeV or 130 and 800 GeV. The search uses proton–
A search for the production of top-quark pairs with the same electric charge (tt or tt¯) is presented. The analysis uses proton-proton collision data at s = 13 TeV, recorded by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. Events with two same-charge leptons and at least two b-tagged jets are selected. Neural networks are employed to define
This paper summarized the efforts performed to understand decay heat estimation from existing spent nuclear fuel (SNF), under the auspices of the Working Party on Nuclear Criticality Safety (WPNCS) of the OECD Nuclear Energy Agency. Needs for precise estimations are related to safety, cost, and optimization of SNF handling, storage, and repository. The physical origins of decay heat (a more correc
Reconstructions and simulations disagree on whether the Holocene exhibited a long-term cooling or warming signal. Anthropogenic land-use could be an important forcing regionally, but available population-based estimates differ widely. We examine transient Holocene climate model simulations forced with three population-based disturbed-land reconstructions and compare this with a fourth scenario der
BACKGROUND: A significant proportion of acute myocardial infarction (AMI) patients have characteristics of high-bleeding -risk (HBR). Their influence on ischaemic and bleeding-events in AMI all-comers is not well described.METHODS: AMI Patients in England and Wales (E&W), and Sweden between 2005 and 2019 were included from MINAP and SWEDEHEART national registries. Patients were categorised acc
The EU Mission on Climate-neutral and Smart Cities aims to enable 100 European cities to become climate-neutral by 2030. However, climate change has the potential to intersect with, exacerbate, and create new patterns of urban injustices, making climate justice a key concern in urban climate governance. Nevertheless, research on the integration of climate justice into urban mitigation strategies a
Wildfires pose hazards for humans through fire proximity and smoke exposure, and are expected to pose increasing risks due to climate change. Existing literature has not extensively inquired how wildfires affect short-term mobility as an adaptive response to these events. We use digital trace mobility data from the Spanish Ministry of Transportation to examine how proximity to wildfires and conseq

This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood-based commodity frontier at the expense of reindeer pastoralists among the Indigenous Sámi people. Through qualitative analysis of a
A case study done in Mbarara, Uganda, investigating to what extent the law about defilement is implemented. Included in the study is also a survey presenting the existing protective structures for young girls in Mbarara who have been subjected for defilement. The focus is on sexual and reproductive health and rights for young women in Mbarara and a holistic gender perspective is used in the analys
Populärvetenskaplig sammanfattning: Sen den industriella revolutionen har koldioxidhalten i atmosfären nästan fördubblats, från 280 ppm till 360 ppm. Detta har skapat stora diskussioner om hur vårt klimat kommer att påverkas. Koldioxid (CO2) är en växthusgas och med detta menas att den absorberar inkommande energi och på så sätt värmer upp vår jord. I denna studie har fokusen lagts på hur vegetatiIncreasing levels of CO2 in the atmosphere may substantially increase net primary productivity (NPP) and thereby increase carbon sequestration by terrestrial ecosystems. Realistic Free Air Carbon Enrichment (FACE) experiments tend to show a NPP enhancement of about 25% if CO2 is elevated by 200 ppm. In this study two generalized vegetation models, the Lund-Postsdam-Jena dynamic generalized vegetat
Sri Lanka has been a leading example among developing nations in the fight against poverty. Human development has been a priority of the Sri Lankan government, and many social indicators are today more in line with those of a developed country. Still poverty is a severe and widespread problem in the country. The economic growth has been under the country’s potential, and the unequal development ha
This thesis examines the legal conformity of Special Tax Zones (STZs) with the principle of non-discrimination under European Union (EU) law, especially when these zones are exempt from State aid rules. STZs are most of the time geographic tax regimes that provide advantages to companies according to their location or their needs in the context of regional development difficulties. Although freque
This thesis investigates the implementation of China’s Solar Energy for Poverty Alleviation Programme (SEPAP), a state-led initiative introduced in 2014 to address rural poverty while supporting the expansion of the domestic photovoltaic (PV) industry. Rather than evaluating outcomes, the study explores how SEPAP was translated from central policy into local practice across two counties in Jiangsu
This thesis investigates the economic consequences of informal sanctions imposed by China on Norwegian salmon exports following the 2010 Nobel Peace Prize awarded to Chinese dissident Liu Xiaobo. Although no formal trade restrictions were announced, Norwegian salmon, a main export item, faced opaque import barriers that significantly disrupted trade flows. Using disaggregated product-level export
Climate change, changing weather patterns, and coastal erosion pose significant risks to the Hebridean isles, which are home to a unique habitat and a cultural landscape known as ‘’machair’. The machair is a coastal landform located exclusively in Scotland, with its majority of existence restricted to the western shore of the Outer Hebrides. This unique habitat, shaped by northern Atlantic winds a
Stormfloder betraktas som ett stort hot mot ekosystem och infrastruktur längs kuster, och hotet ökar på grund av det nuvarande föränderliga klimatet, med alltmer frekventa översvämningshändelser, erosion och sedimentomlagring. I detta sammanhang blir insatser för att identifiera spår av stormfloder i geologiska arkiv allt viktigare för att förstå effekterna av sådana händelser på miljön. Denna stuStorm-surges are considered a major coastal threat to ecosystems and infrastructure in the current changing climate, with increasingly frequent flooding events, erosion and sediment redistribution. In this context, efforts to identify traces of storm-surges in the geological record are becoming increasingly important to understand the impacts of such events on the environment. This project investi
Mobile connectivity is set to change in the coming years due to AI generated data from agents and robotics. How this will develop remains uncertain since this type of data generation is not only a question of connectivity but also compute location and use cases. This creates a need for forward looking scenario analysis for ecosystem players so they can position themselves to win in a new paradigm.
With four years left to fulfill the goals of the UN’s Ocean Decade, it has become increasingly important to find solutions for the threats our oceans are currently facing. French Polynesia has the largest marine protected area in the world and relies heavily on tourism for development. Through semi-structured interviews with stakeholders in the tourism industry in Tahiti, I study their role in mar
