Sammanfattning: Den svenska narkotikapolitikens utvecklingen har under lång tid hindrats av en brist på debatt och vetenskaplighet. På den internationella arenan börjar man se viss förändring i debattklimatet. Cannabis har legaliserat i två delstater i USA och i Köpenhamn föreslås en försöksverksamhet med legal försäljning av cannabis. Den svenska regeringen är oroad över denna utveckling med en m

A variety of pathogenic bacteria can infect humans and the increase in bacteria resistant to common antibiotics is a large threat to human health worldwide. This work presents a method, based on optical DNA mapping (ODM) in nanofluidic channels, that can detect the type of bacterial present in a sample by matching the obtained maps of large DNA molecules to a database of fully assembled bacterial

In this study we derive a single-particle equation of motion, from first principles, starting out with a microscopic description of a tracer particle in a one-dimensional many-particle system with a general two-body interaction potential. Using a harmonization technique, we show that the resulting dynamical equation belongs to the class of fractional Langevin equations, a stochastic framework whic

Abstract I would like to thank my mentor Richard Murray at the Control and Dynamical Systems Department of California Institute of Technology (Caltech) for giving me the opportunity of conducting my master's thesis at Caltech and for his support during the project. I would also like to thank my other mentor Anders Rantzer at the Department of Automatic Control of Lund Institute of Technology u

Thomas Malm, Professor of Human Ecology, has published the anthology On Interdisciplinary Paths - Thoughts and Memories. This collection of essays focuses mainly on Oceania, the part of the world where Thomas has traveled and researched the most. The book takes readers on a journey through time and space and in a highly interdisciplinary trajectory. This aligns with Thomas' research career, which

Sammanfattning I Sverige råder fri bevisprövning med fri bevisvärdering. Det innebär att inga formella regler uppställs för hur ett bevis ska värderas eller vilka metoder som ska tillämpas av domstolen vid bevisvärderingen. Således är det teoretiskt möjligt att vid en ord mot ord situation finna det ställt utom rimligt tvivel att den tilltalade gjort som åklagaren gör gällande. Trots detta är det Summary In Sweden there is a free sifting of evidence with a free evaluation of evidence. This means that no formal rules are imposed on how evidence should be valued or the methods to be applied by the court at the evaluation of evidence. It is theoretically possible to find it beyond reasonable doubt that the accused made as the prosecutor alleges in a situation where one word stands against ano

In this work, we consider expressions for the masses and decay constants of the pseudoscalar mesons in SU(3) chiral perturbation theory. These involve sunset diagrams and their derivatives evaluated at p2=mP2 (P=π, K, η). Recalling that there are three mass scales in this theory, mπ, mK and mη, there are instances when the finite part of the sunset diagrams do not admit an expression in terms of e

We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8. The PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV a

In order to understand the initial partonic state in proton-nucleus and electron-nucleus collisions, we investigate the total, inelastic, and (quasi-)elastic cross sections in pA and gamma-A collisions, as these observables are insensitive to possible collective effects in the final state interactions. We used as a tool the DIPSY dipole model, which is based on BFKL dynamics including non-leading

In the field of computational biology, fluorescence microscopy images often constitute the input source of information. The process of binarization of raw images to delineate interesting objects requires image segmentation into signal and background pixels. Several methods to perform image segmentation exist, the Otsu method being a popular unsupervised example. The Otsu method's lack of pro

Previously, Berg and Purcell found an expression for the diffusion current of particles into a set of receptors in their paper Physics of Chemoreception. These receptors were assumed to be uniformly distributed on a spherical cell's surface and the receptors where idealized as circular patches. For their model, the particles' diffusion constant was the same for all points outside of the ce

The known isospin-breaking contributions to the K → ππ amplitudes are reanalyzed, taking into account our current understanding of the quark masses and the relevant non-perturbative inputs. We present a complete numerical reappraisal of the direct CP-violating ratio ∈′/∈, where these corrections play a quite significant role. We obtain the Standard Model prediction Re (∈′/∈) = (14 ± 5) · 10−4, whi
