A search for four-top-quark production, tttt, is presented. It is based on proton-proton collision data with a center-of-mass energy s=13 TeV collected by the ATLAS detector at the Large Hadron Collider during the years 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb-1. Data are analyzed in both the single-lepton and opposite-sign dilepton channels, characterized by the presenc

The Global Stratotype Section and Point (GSSP) defining the base of the Jurassic System Lower Jurassic Epoch and Hettangian Stage is situated at the Kuhjoch pass, Karwendel Mountains, Northern Calcareous Alps, Austria (47°29'02"N/11°31'50"E). The Triassic-Jurassic (T-J) boundary is exposed at Kuhjoch West and at Kuhjoch East, and corresponds to the first occurrence (FO)

Stimulated by a recent controversy regarding pressure drops predicted in a giant aneurysm with a proximal stenosis, the present study sought to assess variability in the prediction of pressures and flow by a wide variety of research groups. In phase I, lumen geometry, flow rates, and fluid properties were specified, leaving each research group to choose their solver, discretization, and solution s

Objective: The purpose of this study was to determine whether ease of access to alcohol at the neighborhood level moderates the impact of familial liability and marital status on risk for alcohol use disorder (AUD). Method: Individuals in Sweden were divided into those residing in a neighborhood with (n = 14.1%) versus without (n = 85.9%) an alcohol outlet (bars/nightclubs or government stores). A

Objective: The aim of this study was to prospectively determine the incidence of medication-related osteonecrosis of the jaw (MRONJ) and define risk factors in patients with metastatic breast cancer treated with zoledronic acid and/or denosumab. Study Design: In a prospective cohort study performed in Region Skåne, Sweden, from January 1, 2012, until December 31, 2015, all patients with breast can

Background and aims: Although aortic stenosis is the most common valvular heart disease requiring intervention in Europe, the role that diet plays in development of the disease is largely unknown. The pathophysiology of aortic stenosis is however similar to other cardiovascular diseases that fiber intake has been associated with. The aim of this study was consequently to investigate the associatio

With the identification of novel antibiotics from nature being pivotal in the fight against human pathogenic bacteria, there is an urgent need for effective methodologies for expedited screening of crude extracts. Here we report the development and validation of a simple and dye-free antimicrobial assay in 96-well microplate format, for both determination of IC50 values and high-resolution inhibit

OBJECTIVE: To determine whether probiotic prophylaxes reduce the odds of Clostridium difficile infection (CDI) in adults and children. DESIGN: Individual participant data (IPD) meta-analysis of randomized controlled trials (RCTs), adjusting for risk factors. METHODS: We searched 6 databases and 11 grey literature sources from inception to April 2016. We identified 32 RCTs (n=8,713); among them, 18

A search for strongly produced supersymmetric particles is conducted using signatures involving multiple energetic jets and either two isolated leptons (e or μ) with the same electric charge or at least three isolated leptons. The search also utilises b-tagged jets, missing transverse momentum and other observables to extend its sensitivity. The analysis uses a data sample of proton–proton collisi

ClpP functions as the proteolytic subunit of the ATP-dependent Clp protease in eubacteria, mammals and plant chloroplasts. We have cloned a clpP gene, designated clpP1, from the cyanobacterium Synechococcus sp. PCC 7942. The monocistronic 591 bp gene codes for a protein 80% similar to one of four putative ClpP proteins in another cyanobacterium, Synechocystis sp. PCC 6803. The constitutive ClpP1 c

A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks into the lightest neutralino (χ˜10) is reported. It uses LHC proton-proton collision data at a centre-of-mass energy s=13 TeV with an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector in 2015 and 2016. The search is performed in events containing large missing transverse mom

The application of remote sensing methods to assess crop vigor and yields has had limited applications in Sub-Saharan Africa (SSA) due largely to limitations associated with satellite images. The increasing use of unmanned aerial vehicles in recent times opens up new possibilities for remotely sensing crop status and yields even on complex smallholder farms. This study demonstrates the applicabili

Background: Late effects induced by radiotherapy (RT) are of great concern for mediastinal Hodgkin’s lymphoma (HL) patients and it is therefore important to reduce normal tissue dose. The aim of this study was to investigate the impact on the normal tissue dose and target coverage, using various combinations of intensity modulated proton therapy (IMPT), volumetric modulated arc therapy (VMAT) and

In the remedial phase following an accidental radioactive release, it is important that soil decontamination measures are carried out on the areas that contribute most to the radiation dose. In this study, the newly developed concept of isodose lines was applied to the area around typical Swedish dwellings to identify these areas. The influence of the most common building materials in Sweden, wood

Purpose: The aim of the study was to compare overall survival (OS) and disease-free survival (DFS) after open and robotic radical hysterectomy for early-stage cervical cancer. Patients and methods: This was a nationwide population-based cohort study on all women with cervical cancer stage IA1-IB of squamous, adenocarcinoma or adenosquamous histological subtypes, from January 2011 to December 2017,

Islet cell antibodies (ICA) are a specific marker for Type 1 (insulin-dependent) diabetes mellitus. ICA are found in the serum of over 80% of newly diagnosed patients and the levels of ICA are directly of prognostic value. Standardisation of ICA and the uniform reporting of ICA levels in international units is critical to preclinical/clinical research and the development of assays for ICA as diagn
