In this paper, the authors present the characterization experiments of a 20 fs vacuum ultraviolet beam from a high harmonic generation source. The beam hits a silicon sample and passes a triple reflection gold polarizer located inside an ultrahigh vacuum chamber. The polarizer's Malus curve was obtained; the total acquisition time for each point of the curve was 30 s. This aims to be the first vac
In light of concerns about adolescent mental health, there is a need to identify and examine potential pathways to wellbeing in their daily lives. Outdoor environments can offer multiple pathways to wellbeing through opportunities for restoration, physical activity and socialising. However, urbanisation and new lifestyles revolving around the home and the internet are changing young people’s acces
A search for the dimuon decay of the Standard Model (SM) Higgs boson is performed using data corresponding to an integrated luminosity of 139 fb−1 collected with the ATLAS detector in Run 2 pp collisions at s=13 TeV at the Large Hadron Collider. The observed (expected) significance over the background-only hypothesis for a Higgs boson with a mass of 125.09 GeV is 2.0σ (1.7σ). The observed upper li
Our global sustainability challenges are complex and require partnerships and collaboration across disciplines and sectors. As such, as a society, we must value interdisciplinary perspectives and work together to address these challenges. In this episode, we discuss the value of interdisciplinary education to address our complex sustainability challenges. We share the experience from our two inter
Vi presenterar skyddsåtgärder som vidtagits som en del av åtgärdsprogrammet ”Projekt Skräntärna” under perioden 2007–2020 i Sveriges största koloni, Stenarna i Björns skärgård, Uppland. En kombination av övervakning, forskning och förvaltningsåtgärder genomfördes enligt en flexibel strategi, där både etablerade och nya tekniker användes. Varje år under häckningssäsongen gjordes fyra besök för att WE PRESENT CONSERVATI ON ACTI ONS during 2007–2020 as part of the national Caspian Tern Hydroprogne caspia species action plan at Stenarna in the Björn archipelago, Uppland, the largest colony in Sweden. We applied a combination of monitoring, research, and management measures conducted within an adaptive approach frame-work, using both established and novel techniques. The implementation of conse
Knowledge of price formation in fisheries is important in understanding effects of fisheries regulations and the support or resistance to regulations from different stakeholders. This article studies how demand can be traced out using wind speed on a fishing trip. Wind speed is strongly correlated with the quantities of Norwegian lobster (Nephrops) available on the market. Using wind variables as
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton–proton collision. Such LLP signatures are distinct from those of promptly decaying particles t
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The objective of this review is to assess benefits and harms of non-invasive respiratory support for themanagement of transient tachypnea of the newborn.
We present the robot developed within the Hobbit project, a socially assistive service robot aiming at the challenge of enabling prolonged independent living of elderly people in their own homes. We present the second prototype (Hobbit PT2) in terms of hardware and functionality improvements following first user studies. Our main contribution lies within the description of all components developed
This study re-examines standard econometric approaches for detecting adverse and advantageous selection in insurance contracts based on variables that are not used for calculating the insurance premium. We formally demonstrate that existing strategies for detecting selection based on such ‘unused characteristics’ can lead to incorrect conclusions if the estimated coefficients of interest are drive
The thesis explores the ‘missing link’ in the study of priority-setting for research, development, and innovation (RDI), namely the processes of implementing RDI priorities, and the consequences of these processes. It does so by focusing on how choices, actions, and motivations of implementers of RDI priorities established elsewhere in the policy system enact, or carry out, the priorities, resulti
Population ageing is a fact of all advanced economies. Fewer people are born all the while current members live longer. The support which old people have come to depend on, for example through elderly care and pensions, thus becomes increasingly expensive. This accentuates an assurance problem. Although it has been and still is the case that the young are willing to support the currently old, this
The ATLAS physics program at the High Luminosity LHC (HL-LHC) calls for a precision in the luminosity measurement of ±1%. A larger uncertainty would represent the dominant systematic error in some precision measurements, including the Higgs sector. To fulfil such requirement in an environment characterized by up to 140 simultaneous interactions per bunch crossing (200 in the ultimate scenario), AT
For many decades the CERN North Area facility at the Super Proton Synchrotron (SPS) has delivered secondary beams to various fixed target experiments and test beams. In 2018, two new tertiary extensions of the existing beam lines, designated "H2-VLE" and "H4-VLE", have been constructed and successfully commissioned. These beam lines have been designed to provide charged particles of both polaritie
The device or the formulation? Which one governs drug dispersibility from the inhaler? To address this question, three budesonide-containing reservoir DPIs: Novopulmon Novolizer®, Giona Easyhaler® and DuoResp Spiromax®, were analyzed using the Next Generation Impactor, NGI. Thereafter, the devices were carefully opened, emptied, and formulations were switched between devices. Finally, three ‘proto
Knowledge inequalities persist between the Global North and the Global South, but also within countries between privileged and underprivileged segments of society. The purpose of this study is to understand the motives of researchers from basic science and technology to investigate on socially demanded issues as well as the obstacles they encounter. The study is based on the experiences from eleve
