This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for e+μ− and e−μ+ pairs to constrain physics processes beyond the Standard Model. It uses 139fb−1 of proton–proton collision data recorded at s=13 TeV at the LHC. Targeting sources of new physics which prefer final states containing e+μ− to e−μ+, the search contains two broad signal regions wh

Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links

Utilizing building blocks derived from lignocellulose is an attractive strategy towards biobased aromatic polyesters. Here, we present the straightforward synthesis of three new asymmetric di-aromatic diester monomers by one-step reactions of lignin-derived hydroxybenzoates (methyl paraben, methyl vanillate and methyl syringate, respectively) with potentially sugar-based methyl 5-chloromethyl-2-fu

Since the 1970s, environment and energy-related problems have moved to centre stage on many political, business and research agendas. The notion of sustainable development has emerged as the dominant global discourse to adapt societies and economies to novel modes of production and consumption in areas such as transport, energy, housing, agriculture and food. For such shifts, new technology and te

Business angels are a vital source of capital for innovative start-up firms. However, many potentially attractive investment opportunities are rejected during the angel's decision-making process. Information asymmetry, risk and distrust in the relationship between the investor and the entrepreneur result in investment barriers. The concept of proximity has been proposed as a conceptual foundation

This paper has two objectives: first, to estimate the size of informal venture capital market in Sweden, and second, to explore the heterogeneity of informal investing behaviour. Based on quantitative data on 278 informal venture capital investors and 422 investments, this paper provides an estimation of the size of the informal venture capital market in Sweden and an analysis of its structure by

Introduction: While there has been a reduction in specific homicide categories in Sweden, the last decade has witnessed an increase in the overall rate. The escalation is predominantly linked to heightened gun violence associated with criminal gangs. As a result, Sweden faces an extreme rate of shootings and firearm-related homicides, constituting one of the most severe instances across Europe. Ho

Edition of a special issue in the NJEL on the principle of solidarity in EU law - compilation of eight articles

Krönika om mode, smuts och hemlöshet.

Over the past three decades, numbers, particularly those that can be expressed in financial terms, have come to be presented as a form of truth. Today, numbers guide and govern us, and shape and influence who we are, or who we should try to become (Kurunmäki et al., 2016). A few decades ago, this quantifying movement was restricted to a few fields. Today, however, it appears as if no one can escap

This article conceptualizes evolutionary theory as a bridge between existing theorizing in strategic communication on the one hand, the mind sciences on the other. It discusses six core concepts of evolutionary psychology that have a bearing on strategic communication theory: a) the human as a highly flexible social species; b) the regulation of individually-minded vs. collectively-minded behavior

En populärvetenskaplig artikel om Paul Gabriel Ahnfelts spöklika upplevelser som kyrkoherde i Bosarp på 1840-talet.

Mixing in ice covered lakes is caused by through-flow currents, oscillations of the ice cover and by convective currents induced by heat flow from the sediments or by solar radiation penetrating the ice. Mainly from studies in Swedish lakes, current velocities and mixing coefficients are quantified for the different processes generating water movement. Seiche movement caused by wind induced oscill

Within the Anabar shield in the northern part of the Siberia, Late Precambrian mafic igneous units are widespread, which form dyke swarms of different ages of different trends. This paper presents new data on the composition, structure and U-Pb dating of the E-W trending Kengede dyke swarm. Three new U-Pb ID-TIMS baddeleyite ages (1496±7, 1494±3 and 1494±5 Ma) were obtained from three dykes, indic

Emotional and behavioral problems during childhood raise the risk of subsequent developmental of mental disorders. Our aim was to study the association between maternal metal and trace element concentrations during gestation and these problems in 9 year-old children. The study sample comprised Spanish mother-child pairs in the INMA project (n = 1003). Metals and trace elements (As, Cd, Co, Cu, Mo,
