Search for Higgs and Z Boson Decays to φγ with the ATLAS Detector
A search for the decays of the Higgs and Z bosons to a φ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of 2.7 fb-1 collected at s=13 TeV with the ATLAS detector at the LHC. No significant excess of events is observed above the background, and 95% confidence level upper limits on the branching fractions of the Higgs and Z boson decays to φ
Search for resonances in diphoton events at √s=13 TeV with the ATLAS detector
Searches for new resonances decaying into two photons in the ATLAS experiment at the CERN Large Hadron Collider are described. The analysis is based on proton-proton collision data corresponding to an integrated luminosity of 3.2 fb−1 at s=13 TeV recorded in 2015. Two searches are performed, one targeted at a spin-2 particle of mass larger than 500 GeV, using Randall-Sundrum graviton states as a b
Predictors of early postoperative complications after arterial switch operation of newborns with transposition of the great arteries
Background: Lund is one of the two tertiary referral centers for pediatric cardiac surgery in Sweden, with nearly 350 surgical procedures every year. We performed a retrospective analysis of newborns and infants with transposition of the great arteries (TGA) operated with arterial switch (ASO) during the past 10 years. Methods: a single-institution retrospective analysis of nearly 100 newborns and
Ventricular kinetic energy in young fontan patients
Introduction: Four-dimensional (4D) flow magnetic resonance imaging (MRI) enables kinetic energy (KE) quantification of intraventricular blood flow. In this study we aimed to quantify the KE in in patients with univentricular heart and to assess the change in the KE after different types of interventions. Methods: 4D flow MRI was acquired in patients with Fontan circulation (n=12; median age 12, r
Serum biomarkers of early stages of hypertrophic cardiomyopathy in a young population
Background: Hypertrophic cardiomyopathy (HCM) is the most common monogenic cardiac disorder and the leading cause of sudden cardiac death in the young. Although in a majority of HCM cases there are gene mutations coding for sarcomere proteins, the onset for the clinical consequences of these mutations are difficult to predict, as these mutations do not show any clear relationship to the degree of
Ecosystem model analysis of multi-use forestry in a changing climate
The challenge of multi-use forestry is to fulfil a range of economic, ecologic and social goals in a sustainable way, accounting for synergies and trade-offs among the ecosystem services provided. Climate changes add to the complexity via effects on forest ecosystem processes, such as primary production and respiration, and also by adding a new goal on the agenda: the role of forests in climate mi
Demagogues of hate or shepherds of peace? Examining the threat construction processes of warlord democrats in Sierra Leone and Liberia
How are threat images framed and constructed by the so-called warlord democrats (WDs)? Societies that have suffered from large-scale civil wars are commonly permeated by inter-group fear and hate. In these contexts, former military or political leaders of armed groups sometimes become involved in post-war politics. These WDs can act as reconciliation spoilers by making securitising moves, i.e. the
The evolution of host-symbiont dependence
Organisms across the tree of life form symbiotic partnerships with microbes for metabolism, protection and resources. While some hosts evolve extreme dependence on their symbionts, others maintain facultative associations. Explaining this variation is fundamental to understanding when symbiosis can lead to new higher-level individuals, such as during the evolution of the eukaryotic cell. Here we p

A newly discovered autographed Franz Liszt transcription for the harp
It is well known that Franz Liszt was fond of the harp as an instrument, and his use of the harp in the orchestra is innovative. He also befriended and worked with prominent harpists of his time, such as Elias Parish-Alvars, Wilhelm Posse, Jeanne Pohl and Rosalie Spohr. The transcriptions he once made for harp are now lost. However, a recent finding in a collec- tion in a Swedish museum, Murberget
Evidence for Anisotropic Electronic Coupling of Charge Transfer States in Weakly Interacting Organic Semiconductor Mixtures
We present a comprehensive investigation of the charge-transfer (CT) effect in weakly interacting organic semiconductor mixtures. The donor-acceptor pair diindenoperylene (DIP) and N,N′-bis(2-ethylhexyl)-1,7-dicyanoperylene-3,4/9,10-bis(dicarboxyimide) (PDIR-CN2) has been chosen as a model system. A wide range of experimental methods was used in order to characterize the structural, optical, elect
Impedance Matching for VSC-HVDC and Energy Storage Damping Controllers
The small-disturbance electro-mechanical dynamics of a power system can be translated to an equivalent circuit model with inductances and capacitances. Damping control of active power in proportion to local frequency as with a VSC-HVDC link or an energy storage then corresponds to introducing a resistor in the circuit model. This letter shows that impedance matching can be used to select resistor
Minimization of Antenna Quality Factor
Optimal currents on arbitrarily shaped radiators with respect to the minimum quality factor are found using a simple and efficient procedure. The solution starts with a reformulation of the problem of minimizing quality factor Q as an alternative, so-called dual, problem. Taking advantage of modal decomposition and group theory, it is shown that the dual problem can easily be solved and always res
Top 40 questions in coupled human and natural systems (CHANS) research
Understanding and managing coupled human and natural systems (CHANS) is a central challenge of the 21st century, but more focus is needed to pursue the most important questions within this vast field given limited research capacity and funding. We present 40 important questions for CHANS research, identified through a two-part crowdsourcing exercise within the CHANS community. We solicited members
Measurements of the production cross section of a Z boson in association with jets in pp collisions at √s=13 TeV with the ATLAS detector
Measurements of the production cross section of a Z boson in association with jets in proton–proton collisions at s=13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb- 1 collected by the ATLAS experiment at the CERN Large Hadron Collider in 2015. Inclusive and differential cross sections are measured for events containing a Z boson decaying to electrons or muons
How cube-like must magnetic nanoparticles be to modify their self-assembly?
Systems whose magnetic response can be finely tuned using control parameters, such as temperature and external magnetic field strength, are extremely desirable, functional materials. Magnetic nanoparticles, in particular suspensions thereof, offer opportunities for this controllability to be realised. Cube-like particles are particularly mono-disperse examples that, together with their favourable
Feasibility study for the measurement of πn transition distribution amplitudes at P ANDA in p →j /ψπ0 FEASIBILITY STUDY for the MEASUREMENT of ⋯ B. SINGH et al. SINGH
The exclusive charmonium production process in pp annihilation with an associated π0 meson pp→J/ψπ0 is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through the J/ψ→e+e- decay channel with the AntiProton ANnihilation at DArmstadt (PANDA) experiment is investigated. Simulations on signal reconstruction efficiency as well as the background reject

Experimental investigations of turbulent fragmenting stresses in a rotor-stator mixer. Part 2. Probability distributions of instantaneous stresses
Drop fragmentation in high intensity turbulent emulsification processing equipment-such as rotor-stator mixers (RSMs)-has traditionally been described in terms of a stress balance; between the stabilizing stress of the drop and the time-averaged turbulent stress at the most intense position of the flow. As shown in part 1 of this series, this approach is often a fruitful first approximation. Howev
