A search for Higgs boson pair production in the bb¯ WW * decay mode is performed in the bb¯ ℓνqq final state using 36.1 fb −1 of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of events beyond the background expectation is found. Upper limits on the non-resonant pp → HH production cross section of 10 pb a
Sverige kan bli ledande i en radikal omställning av framtidens matproduktion. Genom forskning och utveckling av perenna livsmedelsgrödor kan vi aktivt främja en perenn revolution i jordbruket. Perenna grödor återkommer år efter år utan att behöva sås på nytt, skriver en rad forskare.
How do early-life conditions affect adult mortality? Research has yielded mixed evidence about the influence of infant and child mortality in birth cohorts on adult health and mortality. Studies rarely consider the specific role of mortality within the family. We estimated how individuals’ exposure to mortality as a child is related to their adult mortality risk between ages 18 and 85 in two histo
What can we learn from embryogenesis to increase our understanding of how regeneration of damaged adult lung tissue could be induced in serious lung diseases such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and asthma? The local tissue niche determines events in both embryogenesis and repair of the adult lung. Important constituents of the niche are extrace
Since 2010 when the North American ELKHORN and Baltoscandic PAROVEJA isotope excursions were first described and named, their mutual age relations have remained uncertain, if not controversial. This was at least partly due to the incompleteness of the ELKHORN excursion in its reference section in western Ohio. The unexpected discovery of an apparently complete ELKHORN excursion in a drill core fro
Background: The transcription factor signal transducer and activator of transcription 3 (STAT3) is implicated in cancer drug resistance, metastasis, and immunosuppression and has been identified as a promising therapeutic target for new anticancer drugs. Myeloid-derived suppressor cells (MDSCs) play a major role in the suppression of antitumor immunity and STAT3 is involved in the accumulation, ge
Conservative Voting and the Church: The Religious Dimension in the Electoral Geography of the Conservative (Moderate) Party in Sweden 1921-1998. The geographic patterns of the electoral support for the Conservative (Moderate) party have undergone a profound transformation during the 1921—1998 period studied in this article. Formerly, the party was supported by religious voters to a much higher ext
Aims: To determine the underlying cellular changes and clinical correlates associated with pathology of the hypothalamus in amyotrophic lateral sclerosis (ALS), as hypothalamic atrophy occurs in the preclinical phase of the disease. Methods: The hypothalamus was pathologically examined in nine patients with amyotrophic lateral sclerosis in comparison to eight healthy control subjects. The severity
Arbetet med affischen har gjorts med stöd av Lunds universitet. Ekologen Anna Persson har skrivit informativa texter och Karin Johnson på Biologiska museet har tagit fram humlearter från insektssamlingarna som sedan har illustrerats av Maj Persson, biolog och illustratör. Bilderna visar honan (drottningen) och hanen (drönaren) av varje skånsk humleart.
This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions. Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions. Chap
Systematic data collection in high-income countries has demonstrated a decreasing burn morbidity and mortality, whereas lack of data from low- and middle-income countries hinders a global overview of burn epidemiology. In low- and middle-income countries, dedicated burn registries are few. Instead, burn data are often recorded in logbooks or as one variable in trauma registries, where incomplete o
From November 12th to 13th in 1872, an extreme coastal flood event occurred in the south Baltic Sea. An unusual combination of winds created a storm surge reaching up to 3.5 m above mean sea level, which is more than a meter higher than all other observations over the past 200 years. On the Danish, German, and Swedish coasts, about 300 people lost their lives. The consequences of the storm in Denm
Objective In 2015, new FIGO guidelines for CTG interpretation were presented (FIGO-15). In 2017, the previous Swedish guidelines (SWE-09) were replaced with guidelines adapted to FIGOs (SWE-17). The performance of these three templates had not been scientifically evaluated before its clinical implementation. The objective of this study was to compare the sensitivity and specificity to detect fetal
RelA/SpoT Homologue (RSH) proteins, named for their sequence similarity to the RelA and SpoT enzymes of Escherichia coli, comprise a superfamily of enzymes that synthesize and/or hydrolyze the alarmone ppGpp, activator of the "stringent" response and regulator of cellular metabolism. The classical "long" RSHs Rel, RelA and SpoT with the ppGpp hydrolase, synthetase, TGS and ACT domain architecture
Laminar burning velocities of methylcyclohexane and toluene blended with ammonia have been determined using the heat flux method at atmospheric pressure and initial temperature of 338 K, over equivalence ratios ranging from 0.7 to 1.3 and ammonia blending fractions in the binary fuel mixtures from 0 to 90%. It was observed that the addition of ammonia to methylcyclohexane and toluene leads to a de
Purpose: Cross-sectional studies have shown an association between different coping styles and suicidal behavior. It is unknown whether there is any prospective association between coping behaviors and suicide in the general population. Methods: The study population consisted of participants of the Japanese Public Health Center-based Prospective Study. In the 10-year follow-up questionnaire, subje
Calcite twinning in carbonaceous chondrite meteorites can be used to reconstruct the deformation history and the parent body environment during and/or after aqueous alteration, but the shock pressure threshold at which the twins develop is unknown. Accordingly, the aim of this study is to determine the magnitude of shock pressure that is needed to generate calcite twins. This was done by measuring
