A search for new resonances decaying into jets containing b-hadrons in pp collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 to 7 TeV. The data set corresponds to an integrated luminosity of up to 36.1 fb-1 collected in 2015 and 2016 at s=13 TeV. No evidence of a significant excess of events above the smooth background shape is found. Upper cross-section l

Artikeln behandlar det museala arbetet inom Kongl. Museum från 1790-talet till och med 1850-talet, med omgestaltade rum, förvärv av samlingar, konservatorernas arbete och Konstakademiens utbildning av konstnärer. Under denna period växer museiprofessionen fram, vilket utgör förutsättningen för det nya museet på Blasieholmen på 1860-talet.

Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo-Kobayashi-Maskawa matrix; the corresponding rates for top quark decay processes are experimentally unobservable. Extensions of the Standard Model can generate new flavor-changing neutral current processes, leading to signals which, if observed, w

A search for direct pair production of top squarks in final states with two tau leptons, b-jets, and missing transverse momentum is presented. The analysis is based on proton-proton collision data at s=13 TeV corresponding to an integrated luminosity of 36.1 fb-1 recorded with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. Two exclusive channels with either two hadronically deca

Results from a search for supersymmetry in events with four or more charged leptons (electrons, muons and taus) are presented. The analysis uses a data sample corresponding to 36.1 fb-1 of proton-proton collisions delivered by the Large Hadron Collider at s=13 TeV and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying taus are designed to target a range

We have measured the cross section and single-spin asymmetries from forward W±→μ±ν production in longitudinally polarized p+p collisions at s=510 GeV using the PHENIX detector at the Relativistic Heavy Ion Collider. The cross sections are consistent with previous measurements at this collision energy, while the most forward and backward longitudinal single spin asymmetries provide new insights int

How the brain represents the external world is an unresolved issue for neuroscience, which could provide fundamental insights into brain circuitry operation and solutions for artificial intelligence and robotics. The neurons of the cuneate nucleus form the first interface for the sense of touch in the brain. They were previously shown to have a highly skewed synaptic weight distribution for tactil

Abstract OBJECTIVE To assess the role of four biomarkers of neuroendocrine activation and endothelial dysfunction in the longitudinal prediction of fragility fractures. METHODS We analysed a population-based prospective cohort of 5415 community-dwelling individuals (mean age, 68.9±6.2 years) enrolled in the Malmö Preventive Project followed during 8.1±2.9 years, and investigated the longitudinal Objective To assess the role of four biomarkers of neuroendocrine activation and endothelial dysfunction in the longitudinal prediction of fragility fractures.

INTRODUCTION: Comprehensive geriatric assessment (CGA) is a multidimensional, interdisciplinary diagnostic process used to determine the medical, psychological and functional capabilities of frail older people. The primary aim of our current study is to confirm whether CGA-based outpatient care is superior than usual care in terms of health-related outcomes, resource use and costs.METHODS AND ANAL

Porous silicon with immobilized recognition biomolecules is an attractive platform for many microfluidic chip-based bioanalytical applications. We review the progress in the field since its earliest developments in the 1990s. An improved assay for early detection of prostate cancer has reached clinical evaluation, but there are also exciting developments in both aptamer-based biosensing and mass s

Abstract: The notion of a circular economy (CE) developed out of the work of Kenneth Boulding and others concerned about Earth’s limited resources and its capacity for regeneration. The concept has recently become the heart of an economic perspective influencing governments, companies, and researchers. Core topics examined by those researchers include resource use, economic value, and systems thin

Purpose: The purpose of this paper is to investigate the thermal performance of the cooling plates with conventional straight channel and wavy channel designs. Design/methodology/approach: A three-dimensional model involving coupled fluid flow and heat transfer processes is developed to study the thermal performance of the cooling plates. The effects of wavelength and amplitude on the cooling perf

This book presents, for the first time, the unpublished manuscripts of Lars Hörmander, written between 1951 and 2007. Hörmander himself organised the manuscripts and also wrote the notes explaining their origins, presenting the material in the form he fully intended it to be published in. As his daughter, Sofia Broström, mentions in the Foreword, towards the end of his life, Hörmander "carefully w

Energy efficiency regulations are one of the important policy packages employed for climate mitigation. Recent evaluations from the USA and the European Union (EU) indicate that the setting of minimum mandatory energy performance standards (MEPS) for different products-such as electric motors, TVs, and dishwashers-are among the best-performing climate policies and that these regulations are also c

Volymen gavs ut i samband med utställningen på Deutsches Historisches Museum i Berlin och ger en överblick över de intensiva kulturella kontakterna mellan Tyskland och Skandinavien under "det långa 1800-talet". Forskare från Tyskland, Norge, Sverige och Danmark bidrar med artiklar om politisk kultur, nationalstaternas identitetssökande, växelverkan inom konst, musik och litteratur, konstnärskoloni

Behandlar ett förbisett arkivmatrial som visar vilken roll Oscar (I) och Josephina som kronprinspar i Sverige spelade i de arkitektoniska och konstnärliga förbindelserna mellan Stockholm och München från 1820-talet till och med 1840-talet, däribland kontakterna med Leo von Klenze och Ludwig Schwanthaler.

IntroductionIncreasing oil prices and growing environmental concerns in recent years have driven the development of renewable biofuels. Stimulated by this, the European production of bioethanol, which is produced by fermentation of sugar components in biomass, has nearly doubled in the last two years increasing from 913 million litres in 2005 to 1,565 million litres in 2006. The continuation of th
