A measurement of the tt¯ Z and tt¯ W production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. The analysis uses a data sample of proton–proton collisions at s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb- 1. The inclusive cross se
This paper reports inclusive and differential measurements of the tt̄ charge asymmetry ACin 20.3 fb−1of √s = 8 TeV pp collisions recorded by the ATLAS experiment at the Large Hadron Collider at CERN. Three differential measurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the tt̄ system. The tt̄ pairs are selected in the single-lepton channel
The energy-converting organelles mitochondria and chloroplasts are tightly embedded in cellular metabolism and stress response. To appropriately control organelle function, extensive regulatory mechanisms are at play that involve two-way exchange between the nucleus and mitochondria/chloroplasts. In recent years, our understanding of how mitochondria and chloroplasts provide â € retrograde' feedba
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √S13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb−1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons
The description of ultrafast nonadiabatic chemical dynamics during molecular photo-transformations remains challenging because electronic and nuclear configurations impact each other and cannot be treated independently. Here we gain experimental insights, beyond the Born-Oppenheimer approximation, into the light-induced spin-state trapping dynamics of the prototypical [Fe(bpy) 3 ] 2+ compound by t
Objective: We aimed to summarize key articles published between 2011 and 2015 on the treatment of (recurrent) acute otitis media, otitis media with effusion, tympanostomy tube otorrhea, chronic suppurative otitis media and complications of otitis media, and their implications for clinical practice. Data Sources: PubMed, Ovid Medline, the Cochrane Library, and Clinical Evidence (BMJ Publishing). Re
In recent years, newly arrived students have been in focus in Swedish education, for example, because of the large number of asylum seekers to Sweden which has become a challenge for the Swedish school system (Swedish Schools Inspectorate, 2015). But also because of recent changes in the Education act whereby time spent in reception classes was to be reduced for newly arrived students and they sha
Somatic cells acquire mutations throughout the course of an individual's life. Mutations occurring early in embryogenesis are often present in a substantial proportion of, but not all, cells in postnatal humans and thus have particular characteristics and effects. Depending on their location in the genome and the proportion of cells they are present in, these mosaic mutations can cause a wide rang
This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive blu
The major histocompatibility complex (MHC) encodes proteins that are central for antigen presentation and pathogen elimination. MHC class I (MHC-I) genes have attracted a great deal of interest among researchers in ecology and evolution and have been partly characterized in a wide range of bird species. So far, the main focus has been on species within the bird orders Galliformes and Passeriformes
The Article is by Christa Salamandra and it's about the Nabil Maleh, Giant of Syrian Cinema. Maleh's relationship with the Syrian authorities deteriorated after Fragments, which the director sees as the end of an era in his professional life. A pivotal incident occurred on his birthday in September 1981.
Graphitic nitrogen-doped graphene is an excellent platform to study scattering processes of massless Dirac Fermions by charged impurities, in which high mobility can be preserved due to the absence of lattice defects through direct substitution of carbon atoms in the graphene lattice by nitrogen atoms. In this work, we report on electrical and magnetotransport measurements of high-quality graphiti
The European species of Diglyphus Walker are reviewed. Fifteen species are included. One of these, D. clematidis sp. n., is described as new, and one, D. anadolucus Doganlar, is recorded as new to Europe. Several of the species have their geographical distribution increased as many new country records are introduced. New host records and compilation of host records from the literature are presente
We present a nonperturbative analysis of the power spectrum of energy level fluctuations in fully chaotic quantum structures. Focusing on systems with broken time-reversal symmetry, we employ a finite-N random matrix theory to derive an exact multidimensional integral representation of the power spectrum. The N→ limit of the exact solution furnishes the main result of this study - a universal, par
