Exposure to some polycyclic aromatic hydrocarbons (PAH) increases the risk of cancer and is common, particularly for workers in occupations such as chimney sweeping. In exposed workers, screening of early cancer-related markers provides important information to identify individuals at risk. Here, we aimed to elucidate the associations between PAH exposure and serum levels of cancer-related protein
A search for Higgs boson pair production in the bb¯ bb¯ final state is carried out with up to 36.1 fb−1 of LHC proton-proton collision data collected at s=13 TeV with the ATLAS detector in 2015 and 2016. Three benchmark signals are studied: a spin-2 graviton decaying into a Higgs boson pair, a scalar resonance decaying into a Higgs boson pair, and Standard Model non-resonant Higgs boson pair produ
Results of a search for the pair production of photon-jets - collimated groupings of photons - in the ATLAS detector at the Large Hadron Collider are reported. Highly collimated photon-jets can arise from the decay of new, highly boosted particles that can decay to multiple photons collimated enough to be identified in the electromagnetic calorimeter as a single, photonlike energy cluster. Data fr
The essay gives a brief account of Brecht’s years of exile in Denmark, Sweden and Finland. Central to this story were his close relations with a number of cultural figures in the Nordic countries. The essay also discusses the way Brecht’s writing was transformed during his Nordic exile. It focuses on the fact that he wrote some of his best-known plays and developed his famous theory of Verfremdung
A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying τ-lepton is presented. Two exclusive final states with either exactly one or at least two τ-leptons are considered. The analysis is based on proton-proton collisions at s=13 TeV corresponding to an integrated luminosity of 36.1 fb-1 delivered by the Large Hadron Collider and re

Fredrik N G Andersson diskuterar i bokens sjätte kapitel den gemensamma valutan eurons problem och framtid. Andersson påpekar att utmaningen för euron inte är nationalstatens återkomst utan att nationalstaten aldrig försvann. För att vinsterna med en gemensam valuta skall överstiga kostnaderna måste euroländerna förenas i en politisk union som gemensamt utformar regler för bland annat skatter, arb
We investigate the fragmentation dynamics of adamantane dications produced after core-ionization at the carbon edge followed by Auger decay. The combination of high-resolution electron spectroscopy, energy-resolved electron-ion multi-coincidence spectroscopy and different theoretical models allows us to give a complete characterization of the processes involved after ionization. We show that energ
In this paper, I put forward an argument that sustainability science can make objectively grounded normative claims about what courses of action society should pursue in order to achieve sustainability. From a survey of the philosophy of science, social theory and sustainability science literature, I put forward an approach to justifying these normative arguments. This approach builds on the insig
The IEEE 802.11 standard, often referred to as Wi-Fi, underpins wireless networking applications around the world that impact our daily lives, such as wireless access to the Internet from offices, homes, airports, hotels, restaurants, trains, and aircraft. Today's laptops, tablets, and smartphones are typically equipped with at least one IEEE 802.11 radio. IEEE 802.11 standards have enabled a whol
Engaging students in active participation and collaborative learning is an important pedagogical component of teaching and learning in higher education. Teachers use a variety of activities to engage students, such as interactive lectures, presentations, group activities, and projects. A metaphorical understanding of the teaching-learning process may help in the implementation of innovative and gr
Wooden casks were used extensively to transport goods in medieval Europe but have beenlargely overlooked in Scandinavian marine archaeological studies. We present a study ofcasks recovered from the Danish-Norwegian royal flagship Gribshunden, which sank inthe summer of 1495 outside Stora Ekö Island in southeastern Sweden. Duringexcavations in 2020–2021, archaeologists recovered 135 wooden staves a
Study objectives: Following traumatic events, people frequently experience distressing, involuntary memories of them (i.e., intrusions). Accumulating evidence suggests that sleep facilitates voluntary memory retrieval by supporting memory consolidation, but it is less clear what effect sleep has on intrusions. Recent research has used distressing film clips as a proxy for traumatizing events and e
Interactions between biomolecules are ubiquitous in nature and crucial to many applications including vaccine development; environmentally friendly textile detergents; and food formulation. Using small angle X-ray scattering and structure-based molecular simulations, we explore protein–protein interactions in dilute to semi-concentrated protein solutions. We address the pertinent question, whether
Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. The evaluation of medical images including PET/CT is challeng
