The importance of Monte Carlo event generation for future super colliders is discussed and a brief overview of available programs is given. To emphasize the need for different models of the hadronization process, an example of a measurement is presented where fragmentation effects ‘destroys’ an effect predicted by perturbative QCD also at very high energies. Finally the use of modern programming t
We present preliminary results of a Monte Carlo algorithm that provides a faithful representation of the BDMPS-Z formalism for highly energetic partons interacting in dense QCD matter. In the incoherent limit, the evolution is governed by the probabilities for elastic and inelastic scattering of the highly energetic parton with target constituents in the dense QCD matter. A dynamically evolving fo
In this paper the current bounds on the CKM matrix elements |V td|, |Vts| and |Vtb| from direct measurements are discussed and an improved "model-independent" analysis is proposed.

BackgroundIn light of the opioid epidemic in the United States, there is growing concern about the use of opioids in Sweden as it may lead to misuse and overuse and, in turn, severe public health problems. However, little is known about the distribution of opioid use across different demographic and socioeconomic dimensions in the Swedish general population. Therefore, we applied an intersectional
This paper discusses modern organizational meetings in the public sector, with a focus on time, specifically the planning and scheduling of time among managers. In this qualitative analysis, data were gathered through an ethnographic study of managers in several public organizations, all in Sweden. During interviews and field observations, managers told about their time work involving strategies f
Jet quenching is one of the major discoveries of the heavy-ion program at Rhic. While there is a wealth of data from Rhic that will soon be supplemented with measurements at the Lhc, on the theoretical side the situation is less clear. A thorough understanding of jet quenching is, however, beneficial, as it is expected that medium-induced modifications of jets allow one to characterise properties
A thorough understanding of jet quenching on the basis of multi-particle final states and jet observables requires new theoretical tools. This talk summarizes the status and prospects of the theoretical description of jet quenching in terms of Monte Carlo generators.
Extending the use of Monte Carlo (MC) event generators to jets in nuclear collisions requires a probabilistic implementation of the non-abelian LPM effect. We demonstrate that a local, probabilistic MC implementation based on the concept of formation times can account fully for the LPM-effect. The main features of the analytically known eikonal and collinear approximation can be reproduced, but we
The Monte Carlo model JEWEL 1.0 (Jet Evolution With Energy Loss) simulates parton shower evolution in the presence of a dense QCD medium. In its current form medium interactions are modelled as elastic scattering based on perturbative matrix elements and a simple prescription for medium induced gluon radiation. The parton shower is interfaced with a hadronisation model. In the absence of medium ef
Digitalization has been incorporated into nearly all levels of life in Sweden, including the provision of healthcare service. Accompanied by political strategies that incorporate liberal market logic into public sectors, medicines are made accessible through multiple purchasing channels, especially on the Internet. In this presentation, Rui Liu gives an account of the emergence of a grey health ma

The crisis in fisheries, both in Sweden, Europe and globally, has for decades been a central topic for discussion among stakeholders with different perspectives. However, to regulate a problem and give the policy-making a proper target, there is a need for a common understanding of the problem. Inspired by Maarten Hajer, it is argued that discourses on environmental problems include story-lines an
A strong suppression of non-photonic electrons in Au+Au collisions is observed at Rhic. This is in disagreement with the expected dominance of the energy loss via gluon radiation, which predicts a much weaker suppression of heavy flavours due to the dead cone effect. However, collisional energy loss is also important, as demonstrated recently by the Soft Colour Interaction Jet Quenching model. Bas
We discuss three implementations of the CCFM evolution equations in event generator programs. We find that some of them are able to describe observables such as forward jet rates in DIS at HERA, but only if the so-called consistency constraint is removed. We also find that these results are sensitive to the treatment of non-singular terms in the gluon splitting function.
Background: Incidence and long-term outcomes of choledochal malformations (CMs) in children remain unclear. Methods: Clinical characteristics, operative details, complications, and follow-up data were collected from eight pediatric surgical centers in Sweden, Norway, Denmark, and Finland, which also answered a questionnaire addressing management practices. Results: During 2000–2017, 126 pediatric
Background: The surgical repair of long-gap esophageal atresia (LGEA) is still a challenge and there is no consensus on the preferred method of reconstruction. We performed a systematic review of the surgical treatment of LGEA Gross type A and B with the primary aim to compare the postoperative complications related to the different methods within the first postoperative year. Methods: Systematic
Nitrogen availability often restricts primary productivity in terrestrial ecosystems. Arbuscular mycorrhizal fungi are ubiquitous symbionts of terrestrial plants and can improve plant nitrogen acquisition, but have a limited ability to access organic nitrogen. Although other soil biota mineralize organic nitrogen into bioavailable forms, they may simultaneously compete for nitrogen, with unknown c
