COVID-19 is characterized by a dysregulated and excessive inflammatory response and, in severe cases, acute respiratory distress syndrome. We have recently demonstrated a previously unknown high-affinity interaction between the SARS-CoV-2 spike (S) protein and bacterial lipopolysaccharide (LPS), leading to the boosting of inflammation. Here we present a mouse inflammation model employing the coadm
The inclusive J/ψ meson production in Pb–Pb collisions at a center-of-mass energy per nucleon–nucleon collision of sNN=5.02 TeV at midrapidity (|y|<0.9) is reported by the ALICE Collaboration. The measurements are performed in the dielectron decay channel, as a function of event centrality and J/ψ transverse momentum pT, down to pT=0. The J/ψ mean transverse momentum 〈pT〉 and rAA ratio, defined as
The Swedish gender-inclusive pronoun hen can be used generically (referring to anyone), or specifically (referring to non-binary gender identities). Three studies tested evaluations and use of hen, and individual-level predictors. In Study 1 (N = 2145), specific hen was slightly favoured over generic hen. In Study 2 (N = 297), hen was more negatively evaluated than binary pronouns, and generic hen
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of s=13 TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding
Different signal frequencies from body tissues, muscles fat etc affects the EMG signals. The signal frequencies from body organ can considered as noise which affects the output and hence for better signal output noised should be minimised. Traditional EMG machines supports analogue filtering while residual noises carried by signal channels. For good and better signal aggregation and useful data ga
Nedstängningar har liten smittskyddseffekt och stora ekonomiska och sociala kostnader. Pandemilagen står inte på stabil vetenskaplig grund utan är ett oroväckande tecken på vad som rimligen bör diagnostiseras som pandemipopulism, skriver Fredrik NG Andersson och Lars Jonung vid Ekonomihögskolan i Lund.
Students' understanding of forces in circular motion is often incomplete. The problems are not limited to confusions about centripetal acceleration and centrifugal forces. This paper considers possible effects of different interventions by a teacher who has discovered the many types of free-body diagrams drawn by students for circular motion in a vertical plane. Students' free-body diagrams often
I report on the opening ceremony of the International Year of Light and Light-based Technologies 2015 (IYL2015), which took place at the UNESCO headquarters in Paris, France, on 19-20 January 2015. Over the two days, more than 1000 participants from all over the world learned more about the fundamental properties of light and advanced photonics applications, the history of optics and its applicati
Det finns i princip två vägar för att öka den sociala och dämpa smittspridningen: antingen en strategi byggd på tvång eller att ansvarstagande medborgare av fri vilja anpassar sitt beteende. Frihet under ansvar har visat sig fungera bra, skriver nationalekonomerna Fredrik NG Andersson och Lars Jonung.
Purpose: The purpose of this article is to offer new insights into crisis communication in service ecosystems. The authors present a framework to conceptually categorize service crises and then analyze key aspects of crisis communication among different stakeholders in a service ecosystem. Design/methodology/approach: Building on crisis communication and service ecosystems research, we propose a f
Ekonomin befinner sig i snabb uppgång. Nu krävs stram stabiliseringspolitik och reformer som höjer tillväxten under lång tid – inte expansiv politik med 74 miljarder i ökade utgifter. Det skriver nationalekonomerna Fredrik N G Andersson och Lars Jonung.
A search for magnetic monopoles and high-electric-charge objects is presented using 34.4 fb-1 of 13 TeV pp collision data collected by the ATLAS detector at the LHC during 2015 and 2016. The considered signature is based upon high ionization in the transition radiation tracker of the inner detector associated with a pencil-shape energy deposit in the electromagnetic calorimeter. The data were coll
The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity (| y| < 0.5) are measured in proton-proton collisions at s = 13 TeV as a function of the charged particle multiplicity, using the ALICE detector at the LHC. The production rates of KS0, Λ , Ξ , and Ω increase with the multiplicity faster than what is reported for inclusive charged particles. The increa
Midrapidity production of π±, K±, and (p¯)p measured by the ALICE experiment at the CERN Large Hadron Collider, in Pb-Pb and inelastic pp collisions at sNN=5.02 TeV, is presented. The invariant yields are measured over a wide transverse momentum (pT) range from hundreds of MeV/c up to 20 GeV/c. The results in Pb-Pb collisions are presented as a function of the collision centrality, in the range 0-
This paper presents results of searches for the electroweak production of supersymmetric particles in models with compressed mass spectra. The searches use 139 fb-1 of s=13 TeV proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider. Events with missing transverse momentum and two same-flavor, oppositely charged, low-transverse-momentum leptons are selected, and
