Stem cells are unspecialized cells able to divide and produce copies of themselves and having the potential to differentiate, i.e. to produce other cell types in the body. Because of the latter ability, the scientists investigate their possible use in regenerative medicine. Especially embryonic stem cells have huge therapeutic potential because they can give rise to every cell type in the body as
A search for the decay to a pair of new particles of either the 125 GeV Higgs boson (h) or a second charge parity (CP)-even Higgs boson (H) is presented. The data set corresponds to an integrated luminosity of 20.3 fb(-1) of pp collisions at root s = 8 TeV recorded by the ATLAS experiment at the LHC in 2012. The search was done in the context of the next-to-minimal supersymmetric standard model, i
In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H+, t -> bH(+), in addition to the Standard Model decay t -> bW. Since W bosons decay to the three lepton generations equally, while H+ may predominantly decay into tau nu, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays. T
A new block-oriented language called Friend is proposed. It is designed to support for the implementation of flexible and adaptive embedded control systems. Requirements on a controller are specified using contracts. The use of contracts simplifies the design and implementation of embedded systems that can adapt to altered operating conditions. The contracts allow the system to negotiate about res
Background: High breast density is a risk factor for breast cancer. However, whether density is a prognostic factor is debatable. Also, tumor appearances are related to tumor characteristics. Here we investigate the relationship between breast cancer-specific survival and mammographic breast density and mammographic tumor appearances. Methods: Women in the Malmö Diet and Cancer study with invasive
Primary and secondary bile acids (BAs) influence metabolism and inflammation, and the gut microbiome modulates levels of BAs. We systematically explore the host genetic, gut microbial, and habitual dietary contribution to a panel of 19 serum and 15 stool BAs in two population-based cohorts (TwinsUK, n = 2,382; ZOE PREDICT-1, n = 327) and assess changes post-bariatric surgery and after nutritional
A search for diphoton resonances in the mass range between 10 and 70 GeV with the ATLAS experiment at the Large Hadron Collider (LHC) is presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 138 fb −1 at a centre-of-mass energy of 13 TeV recorded from 2015 to 2018. Previous searches for diphoton resonances at the LHC have explored masses down to 65 GeV,
Whilst research on climatic effects on fungal populations and communities (particularly of soil and litter-specialised species) has been done extensively, empirical examples of the impacts of climate change on airborne fungi are still lacking. Using a hot-air balloon to sample fungal spores during the winters of 2022 and 2023, here, we show the effects of warmer winter temperatures on airborne fun
Leaf area index is an important metric for characterising the structure of vegetation canopies and scaling up leaf and plant processes to assess their influence on regional and global climate. Earth observation estimates of leaf area index have increased in recent decades, providing a valuable resource for monitoring vegetation changes and evaluating their representation in land surface and earth
The extent to which different magnitudes and directions of temperature fluctuations explain long-term trends in aquatic invertebrate body size is largely unknown. Using elevational gradients and paleolimnological reconstructions, we tested the hypotheses that the size of subfossil chironomid (non-biting midges) head capsules (HCs) will covary with temperature changes, with opposite morphometric ch
Objective: To study the impact of tumour necrosis factor-α inhibitor (TNFi) therapy on the use of non-steroidal anti inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) in Iceland. Method: This registry cohort study used data from the nationwide database on biologics in Iceland (ICEBIO) and the Icelandic Prescriptio
Environmental peacebuilding broadly refers to how sustainable management of natural resources can support prevention, mitigation, and resolution of conflict, as well as recovery after conflict. Shared natural resources constitute a common environmental challenge around which cooperation may be fostered. Environmentally damaging fires in conflict areas have received little attention from the peaceb
Carbonyl sulfide (COS) is a promising tracer for the estimation of terrestrial ecosystem gross primary production (GPP). However, understanding its non-GPP-related sources and sinks, e.g., anthropogenic sources and soil sources and sinks, is also critical to the success of the approach. Here we infer the regional sources and sinks of COS using continuous in situ mole fraction profile measurements
This paper studies the impact of land use and land cover change (LULCC) on the climate around 2500 years ago (2.5 ka), a period of rapid transitions across the European landscape. One global climate model was used to force two regional climate models (RCMs). The RCMs used two land cover descriptions. The first was from a dynamical vegetation model representing potential land cover, and the second
Denna magisteruppsats tar upp voice browsing utifrån den nya standarden VoiceXML. Uppsatsen är en undersökning av VoiceXML och XML. Undersökningens fokus ligger främst på de båda teknikerna, vars fördelar såväl som nackdelar presenteras och analyseras. XML ställs även i jämförelse med befintliga kompletterande tekniker som till exempel dess föregångare SGML och HTML. Undersökningen belyser och dis
