Probing the Quantum Interference between Singly and Doubly Resonant Top-Quark Production in pp Collisions at s =13 TeV with the ATLAS Detector

This Letter presents a normalized differential cross-section measurement in a fiducial phase-space region where interference effects between top-quark pair production and associated production of a single top quark with a W boson and a b-quark are significant. Events with exactly two leptons (ee, μμ, or eμ) and two b-tagged jets that satisfy a multiparticle invariant mass requirement are selected

Evidence against Anomalous Compositions for Giants in the Galactic Nuclear Star Cluster

Very strong Sc i lines have recently been found in cool M giants in the Nuclear Star Cluster (NSC) in the Galactic center. Interpreting these as anomalously high scandium abundances in the Galactic center would imply a unique enhancement signature and chemical evolution history for NSCs, and a potential test for models of chemical enrichment in these objects. We present high resolution K-band spec

Nutritional modulation of AMPK-impact upon metabolic-inflammation

Nutritional status provides metabolic substrates to activate AMP-Activated Protein Kinase (AMPK), the energy sensor that regulates metabolism. Recent evidence has demonstrated that AMPK has wider functions with respect to regulating immune cell metabolism and function. One such example is the regulatory role that AMPK has on NLRP3-inlflammasome and IL-1β biology. This in turn can result in subsequ

Retinal Cryo-sections, Whole-Mounts, and Hypotonic Isolated Vasculature Preparations for Immunohistochemical Visualization of Microvascular Pericytes

Retinal pericytes play an important role in many diseases of the eye. Immunohistochemical staining techniques of retinal vessels and microvascular pericytes are central to ophthalmological research. It is vital to choose an appropriate method of visualizing the microvascular pericytes. We describe retinal microvascular pericyte immunohistochemical staining in cryo-sections, whole-mounts, and hypot

Marginal-Zone B-Cells are main producers of IgM in humans, and are reduced in patients with autoimmune vasculitis

In mice, B1 and marginal zone (MZ) B-cells play an important role in prevention of autoimmunity through production of regulatory cytokines and natural antibodies. There is limited knowledge about the human counterparts of these cells. We therefore investigated functions of MZ-like B-cells and the frequency of circulating MZ-like and B1-like B-cells in healthy controls (HC), as well as in patients

Darriwilian (Middle Ordovician) chemostratigraphy linked to graptolite, conodont and trilobite biostratigraphy in the Fågelsång-3 drill core, Scania, Sweden

A recent core drilling in the geologically classical Fågelsång area resulted in a 58.70-m-long drill core through the lowermost Sandbian Sularp Shale, the Darriwilian Almelund Shale and Komstad Limestone, and part of the late Tremadocian to earliest Darriwilian Tøyen Shale. The shales contain zone index graptolites that are used for an update of the standard Darriwilian graptolite zone succession

PalCom MIST: a Metaprotocol for Internet Systems of Things

Future applications of internet of things (IoT) will go far beyond connecting sensors to the internet. The real challenge lies in how to easily build well working systems of things: well integrated distributed applications that support users, yet built from a variety of devices running on a variety of networks and protocols, and including services that were not designed to interoperate.Based on ou

Macro- and microvascular complications of diabetes: Studies on NFAT (Nuclear Factor of Activated T-cells) as a novel target for the treatment of atherosclerosis and vascular dysfunction in diabetes.

Diabetes is associated with devastating chronic complications including coronary heart disease and stroke (macrovascular complications) as well as microvascular disorders leading to damage of the small vessels and the development of retinopathy, nephropathy and neuropathy. The underlying pathogenesis is not clear, but hyperglycemia has been identified as an important risk factor. Previous work fro

High prevalence of undiagnosed COPD among patients evaluated for suspected myocardial ischaemia

Objective: Chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD) are leading causes of global morbidity and mortality. Despite the well-known comorbidity between COPD and CAD, the presence of COPD may be overlooked in patients undergoing coronary evaluation. We aimed to assess the prevalence of undiagnosed COPD among outpatients evaluated due to suspected myocardial ischem

Can Euroscepticism Contribute to a European Public Sphere? : The Europeanization of Media Discourses about Euroscepticism across Six Countries

This study compares the media discourses on euroscepticism in 2014 in six countries (the UK, Ireland, France, Spain, Sweden and Denmark). We assessed the extent to which the mass media's reporting of euroscepticism indicates the Europeanization of public spheres. Using a mixed-methods approach combining latent Dirichlet allocation (LDA) topic modelling and qualitative coding, we find that approxim

Physical and virtual spaces among the Palestinian diaspora in Malmö

Through the construction of a Palestinian diasporic topography of Malmö, this chapter focuses on the interrelationship of multiple spaces of action and interaction of Palestinians, locally and transnationally. In addition, given the different identifications and migration trajectories of Malmö Palestinians (originating in the West Bank, Gaza but also Syria, Lebanon, Jordan, and beyond, as well as

Shrunken Pore Syndrome Is Associated With Increased Levels of Atherosclerosis-Promoting Proteins

Introduction: Shrunken pore syndrome (SPS), originally defined by cystatin C-based estimated glomerular filtration rate (eGFRcystatin C) being less than 60% of creatinine-based estimated glomerular filtration rate (eGFRcreatinine) in the absence of extrarenal influences on the plasma levels of cystatin C or creatinine, is associated with a high increase in mortality, even in the absence of reduced

Relating aerosol mass spectra to composition and nanostructure of soot particles

The composition and carbon nanostructure of soot are important parameters influencing health and climate effects, and the efficacy of soot mitigation technologies. We used laser-vaporization, electron-ionization aerosol mass spectrometry (or SP-AMS) to systematically investigate relationships between aerosol mass spectra, carbon nanostructure (HRTEM), and composition (thermal-optical carbon analys

Streaming instability of multiple particle species in protoplanetary disks

The radial drift and diffusion of dust particles in protoplanetary disks affect both the opacity and temperature of such disks, as well as the location and timing of planetesimal formation. In this paper, we present results of numerical simulations of particle-gas dynamics in protoplanetary disks that include dust grains with various size distributions. We have considered three scenarios in terms

The Angantyr model for heavy-ion collisions in Pythia8

We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti

Differences in spatial resolution and contrast sensitivity of flight control in the honeybees Apis cerana and Apis mellifera

Visually guided behaviour is constrained by the capacity of the visual system to resolve detail. This, in turn, is limited by the spatial resolution and contrast sensitivity of the underlying visual system. Because these properties are interdependent and vary nonuniformly, it is only possible to fully understand the limits of a specific visually guided behaviour when they are investigated in combi
