Single-file diffusion is a theoretically challenging many-body problem where the calculation of even the simplest observables, e.g. mean square displacement, for a tracer particle requires an elaborate mathematical machinery. There is therefore a need for simple approaches which provide intuitive understandings and predict qualitatively correct behaviours. Here we put forward a scaling-type method

Defocus changes the visual contrast sensitivity function, thereby creating a complex curve with local dips and peaks. Since underwater vision in humans is severely defocused, we used optical theory and the phenomenon of spurious resolution to predict how well humans can see in this environment. The values obtained correspond well with experimental measurements of underwater human acuity from earli

We study the phase behavior of single homopolymers in a simple hydrophobic/hydrophilic off-lattice model with sequence independent local interactions. The specific heat is, not unexpectedly, found to exhibit a pronounced peak well below the collapse temperature, signalling a possible low-temperature phase transition. The system size dependence at this maximum is investigated both with and without

In a few recent papers we introduced the chirality-flow formalism, which was shown to make calculations of tree-level Feynman diagrams simple and transparent. Chirality flow, which is based on the spinor-helicity formalism, allows to often immediately analytically write down a tree-level Feynman diagram in terms of spinor inner products. In this paper, we argue that there is also a significant sim

Kajsa Brolin explores how our genes and environment affect the risk of developing Parkinson’s disease. March 27, she defends her Ph.D. project partly based on MultiPark’s biobank sample collection. Here, she tells about the newly discovered genetic risk factor that might be specific to people in the southern part of Sweden. And is coffee really protective?

This article is over 5 years old, and the information may therefore be outdated. LUCSUS new postdoctoral researcher, Eric Hoddy, aims to develop a better understanding of the governance of climate change adaptation in informal urban settlements. In this short interview, he highlights what sustainability challenges he finds most interesting, what he likes about working at LUCSUS so far, and what he

Denna studie syftar till att undersöka hur den visuella kommunikationen i dagens samhälle kan användas som ett strategiskt kommunikativt verktyg. Mer specifikt ämnar undersökningen att bidra med djupare kunskap kring hur unga kvinnors kroppsaktivistiska stillbilder från Instagram kan tolkas i relation till blick-teori samt om dessa bilders visuella kommunikation kan bidra till att motarbeta den maThis study aims to investigate how visual communication in today´s society can be used as as a strategic communicative tool. More specifically, the study aims to contribute with deeper knowledge of how young women's body activist still images from Instagram can be interpreted in relation to gaze theory, and whether their visual communication can contribute to counteracting the male gaze's

I AM GRATEFUL TO Dien Ho and James Phillips for their comments on my article (Mulinari, 2018). Although they approach the topic from different perspectives, they both seem to find my account of the evolution of monoamine theories into neuroplasticity theories to be compelling. They especially seem to find my principal argument to be persuasive: Until quite recently, the use of drugs to generate an

The finite temperature behaviour of lattice QCD with dynamical quarks for small number of flavours Nf is investigated. Simulations have been performed on lattices of size N3σ·4 with Nσ=8 and 12 and staggered fermions of mass ma=0.1 using a hybrid algorithm. We find that the two state signal at the critical point of the pure gauge theory, which is taken as sign for a fiorst order phase transition,

A brief review is given for the use of feed-back artificial neural networks (ANN) to obtain good approximate solutions to combinatorial optimization problems. The key element is the mean field approximation (MFT), which differs from conventional methods and "feels" its ways towards good solutions rather than fully or partly exploring different possible solutions. The methodology, which is illustra

Parton shower algorithms are key components of theoretical predictions for high-energy collider physics. Work toward more accurate parton shower algorithms is thus pursued along many different avenues. The systematic treatment of subleading color corrections in parton shower algorithms is, however, technically challenging and remains elusive. In this article, we present an efficient and numericall

We consider the central exclusive production of qq̄ pairs and Higgs boson in proton-proton collisions at LHC. The amplitude for the process is derived within the k -factorization approach and considered in different kinematical asymptotics, in particular, in the important high quark transverse momenta and massless quark limits. Quark helicity and spin-projection amplitudes in two different frames

I svensk rätt finns bestämmelser om skadebegräsning 70 § köplagen. Att bedöma huruvida denna skadebegränsningsplikt ska gälla också utomobligatoriskt har genom åren vållat rättsvetenskapsmännen vissa bekymmer. Denna framställning har till syfte att undersöka och klargöra innebörden av skadebegränsningsplikten i svensk rätt. Särskilt fokus ligger här på de lojalitetshänsyn som anses motivera skadebIn Swedish law there are provisions on mitigation in Section 70 of the Sale of Goods act. The assessment of whether this mitigation obligation should also apply non-contractually has caused legal scientists some concerns over the years. The purpose of this paper is to investigate and clarify the meaning of the obligation to mitigate your losses in Swedish law. Particular attention is given to the

Attempts of Magain et al. to detect the host galaxy of the bright quasi-stellar object (QSO) HE0450-2958 have not been successful. We suggest that the supermassive black hole (SMBH) powering the QSO was ejected from the observed ultraluminous infrared galaxy (ULIRG) at the same redshift and at 1.5 arcsec distance. Ejection could have been caused either by recoil due to gravitational wave emission

We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentati
