A search is presented for the production of a single top quark via left-handed flavour-changing neutral-current (FCNC) interactions of a top quark, a gluon and an up or charm quark. Two production processes are considered: u+ g→ t and c+ g→ t. The analysis is based on proton–proton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. The data set correspond
Antennas are one of the key components that empower a new generation of wireless technologies, such as 5G and new radar systems. It has been shown that antenna design strategies based on modal theories represent a powerful systematic approach to design practical antenna systems with high performance. In this thesis, several innovative multi-antenna systems are proposed for wireless applications in
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in th
The monoclonal gammopathies are a group of disorders associated with monoclonal proliferation of plasma cells. The characterization of specific entities is an area of difficulty in clinical practice. The International Myeloma Working Group has reviewed the criteria for diagnosis and classification with the aim of producing simple, easily used definitions based on routinely available investigations
We propose the Positive Resampler to solve the problem associated with event samples from state-of-the-art predictions for scattering processes at hadron colliders typically involving a sizeable number of events contributing with negative weight. The proposed method guarantees positive weights for all physical distributions, and a correct description of all observables. A desirable side product of
Thermoresponsive structures in the 5'-untranslated region of mRNA are known to control translation of heat shock and virulence genes. Expression of many rhizobial heat shock genes is regulated by a conserved sequence element called ROSE for repression of heat shock gene expression. This cis-acting, untranslated mRNA is thought to prevent ribosome access at low temperature through an extended secon
Background: The EsPhALL2004 randomised trial showed a 10% advantage in disease-free survival for short, discontinuous use of imatinib after induction compared with no use of imatinib in patients with Philadelphia chromosome-positive acute lymphoblastic leukaemia receiving Berlin-Frankfurt-Münster chemotherapy and haemopoietic stem-cell transplantation (HSCT). Other contemporary studies showed an a
An audio paper on H e (a) r; a soundscape connected to ecology, acoustics and embodiment, drawing on encounters and what happens in the connection. A fluctuation between hear-here-hér*-her. Originating in a work for the ensemble Nordic Affect’s concert at Nordic Music Days 2016, the piece has now been developed into both a quadrophonic and stereo version of H e (a) r (2017/18). The work has been r
During the last decades, coherent anti-Stokes Raman spectroscopy (CARS) has been an important tool in combustion research. The focus of this thesis is the improvement of the capability of the pure rotational CARS (RCARS) technique for this type of applications. The technique is used to measure temperatures and relative species concentrations in the gas phase and thermometry is performed by fitting
Qualitative and quantitative visualizations of transonic turbomachinery flows provide essential information on compressibility and Mach number effects on boundary layer development, shock-boundary layer interactions, and trailing edge flows. Background oriented Schlieren (BOS) is a relatively new optical technique that allows capturing unsteady density gradient fields through turbomachinery cascad
Purpose: To evaluate patients with central retinal vein occlusion (CRVO) and neovascular glaucoma (NVG) using electrophysiology in order to gain better understanding of visual outcome and risk factors, such as previously diagnosed primary open-angle glaucoma (POAG). Methods: Eighty-three patients (83 eyes) initially presenting with CRVO and examined with full-field electroretinography (ERG) within
This paper investigates the confluence of artificial intelligence (AI), the performing arts, and emotion communication, focusing on how generative AI and social robotics – today’s forefront disruptive technologies – can facilitate an exploration of emotional dynamics across artistic mediums. Drawing on the intermedial and multimodal capacities of opera, this paper presents AI-enhanced opera as a p
The Hidden Conference is a film in three parts. Each projection investigates the storage facilities of a European museum, where artworks are kept while not on display. About the Discontinuous History of Things We See and Don’t See, projected in the first room, was filmed at the stores of the Neue Nationalgalerie in Berlin in 2010. About the Shelf and Mantel, shown in the following gallery, was sho
Popular Abstract in English A large variety of microorganisms are present in nature and have indispensable roles in recycling carbon, remediation of the environment, agriculture, and also in providing health benefits to humans. Microorganisms are microscopic versatile living factories that can consume several different natural as well as synthetic compounds for their growth and also produce differA shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chem
We present a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized. The method is based on fabrication of high aspect ratio silicon microstructures using deep reactive ion etching (Bosch technique) of dense grating arrays and followed by conformal electroplating
The catalytic oxidation of HCl by molecular oxygen (Deacon process) over ceria allows the recovery of molecular chlorine from the omnipresent HCl waste produced in various industrial processes. In previous density functional theory (DFT) model-calculations by Amrute et al. [ J. Catal. 2012, 286, 287−297.], it was proposed that the most critical reaction step in this process is the displacement of
Von Economo neurons (VEN) are bipolar neurons located in the anterior cingulate cortex (ACC) and the frontoinsular cortex (FI), areas affected early in behavioural variant frontotemporal dementia (bvFTD), in which VEN may constitute a selectively vulnerable cellular population. Aim A previous study has shown a selective loss of VEN in FTD above other neurons in the ACC of FTD. The aim of this stud
In most genres of fiction representations of a profession, discipline or calling must broadly resonate with the conceptions of that role held by audiences. But very few represenations of PR practice to be found in novels written by UK-based writers draw a picture of PR activity that sits comfortably with the ”idealised” models offered by organisations such as the Chartered Institute of Public Re
