Different approaches to anion exchange membranes (AEMs) are currently intensively investigated with the aim to develop materials for application in electrochemical energy devices such as alkaline fuel cells and electrolysers.1 One of the major challenges is to identify feasible synthetic strategies to AEM materials with sufficient long-term chemical and thermal stability. Studies of different smal
The application of anion exchange membranes (AEM) in their hydroxide (OH–) form (sometimes denoted by HEM) as separators in low temperature fuel cells is a matter of ongoing research. OH– conductivity close to the proton conductivity of PEMs (such as the well-established Nafion®) are quite common [i] for high levels of hydration, and the reactivity of OH– with CO2 in air (used as oxidant in fuel
The angular distributions of Drell-Yan charged lepton pairs in the vicinity of the Z-boson mass peak probe the underlying QCD dynamics of Z-boson production. This paper presents a measurement of the complete set of angular coefficients A0−7 describing these distributions in the Z-boson Collins-Soper frame. The data analysed correspond to 20.3 fb−1 of pp collisions at s=8 TeV, collected by the ATLA
Abstract: A measurement of the cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of s=8 TeV is presented. The measurement covers the pseudorapidity ranges |ηγ | < 1.37 and 1.56 ≤ |ηγ | < 2.37 in the transverse energy range 25 < ET γ < 1500 GeV. The results are based on an integrated luminosity of 20.2 fb−1, recorded by the
A search for singly produced vector-like Q quarks, where Q can be either a T quark with charge + 2 / 3 or a Y quark with charge - 4 / 3 , is performed in proton–proton collisions recorded with the ATLAS detector at the LHC. The dataset corresponds to an integrated luminosity of 20.3 fb- 1 and was produced with a centre-of-mass energy of s=8 TeV. This analysis targets Q→ Wb decays where the W boson
This paper presents a measurement of the double-differential cross section for the Drell-Yan Z/γ∗ → ℓ+ℓ− and photon-induced γγ → ℓ+ℓ− processes where ℓ is an electron or muon. The measurement is performed for invariant masses of the lepton pairs, mℓℓ, between 116 GeV and 1500 GeV using a sample of 20.3 fb−1 of pp collisions data at centre-of-mass energy of s=8 TeV collected by the ATLAS detector a
This paper describes a measurement of fiducial and differential cross sections of gluon-fusion Higgs boson production in the H → W W∗→ eνμν channel, using 20.3 fb−1 of proton-proton collision data. The data were produced at a centre-of-mass energy of s=8 TeV at the CERN Large Hadron Collider and recorded by the ATLAS detector in 2012. Cross sections are measured from the observed H→ W W∗→ eνμν sig
WNT5A is a secreted signaling protein that promotes migration and invasion of oral squamous cell carcinoma (OSCC) cells through activation of non-canonical WNT signaling. Here, we examined expression of WNT5A, β-catenin, and E-cadherin by immunohistochemistry in 21 human diagnostic incision biopsies that each had regions of oral mucosa with a normal appearance adjacent to the affected tissue, dysp
A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying tau lepton has been performed using 3.2 fb-1 of proton–proton collision data at s=13TeV recorded by the ATLAS detector at the Large Hadron Collider in 2015. Two exclusive final states are considered, with either exactly one or at least two tau leptons. No excess over the Standa
Mercury is a severe pollutant in China. A novel mobile laser spectroscopy laboratory was constructed and used in differential absorption lidar mapping in major Chinese cities, a heavily polluted mining area and an archeological site.
Heterogeneous catalysts for selective oxidation of C-H bonds were synthesized by co-polymerization of new N-heterocyclic carbene-palladium(II) (NHC-PdII) monomers with divinylbenzene. The polymer-supported NHC-PdII-catalysed undirected C-H acetoxylation of simple and methylated arenes as well as polyarenes, with similar or superior efficiency compared to their homogeneous analogues. In particular,
This book probes the relationship between Martin Heidegger and theology in light of the discovery of his Black Notebooks, which reveal that his privately held Antisemitism and anti-Christian sentiments were profoundly intertwined with his philosophical ideas. Heidegger himself was deeply influenced by both Catholic and Protestant theology. This prompts the question as to what extent Christian anti
During the last few years most work done on the task of image segmentation has been focused on deep learning and Convolutional Neural Networks (CNNs) in particular. CNNs are powerful for modeling complex connections between input and output data but lack the ability to directly model dependent output structures, for instance, enforcing properties such as smoothness and coherence. This drawback mot
A fully automatic system for abdominal organ segmentation is presented. As a first step, an organ localization is obtained via a robust and efficient feature registration method where the center of the organ is estimated together with a region of interest surrounding the center. Then, a convolutional neural network performing voxelwise classification is applied. The convolutional neural network co
Development of optical techniques in medical applications can be difficult due to limited access to realistic phantoms. Here a 3-D printed model based on CT-images of the thorax of an infant is developed and tested.
[NiFe] hydrogenases catalyse the reversible conversion of molecular hydrogen to protons and electrons. This seemingly simple reaction has attracted much attention because of the prospective use of H2 as a clean fuel. In this paper, we have studied how H2 binds to the active site of this enzyme. Combined quantum mechanical and molecular mechanics (QM/MM) optimisation was performed to obtain the geo
