Searches for heavy diboson resonances in pp collisions at √s=13 TeV with the ATLAS detector

Searches for new heavy resonances decaying to WW, WZ, and ZZ bosons are presented, using a data sample corresponding to 3.2 fb−1 of pp collisions at s=13 TeV collected with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting ννqq, ℓνqq, ℓℓqq and qqqq final states are combined, searching for an arrow-width resonance with mass between 500 and 3000 GeV. The discriminating variabl

Heritability of tarsus length in cross-fostered European Starling broods

A cross-fostering experiment demonstrated that tarsus length of European starlings (Sturnus vulgaris) was heritable. The tarsus length of the foster-parent had no effect. A full-sib resemblance analysis showed that sibs were much more similar in tarsus length than explained by heritability alone. This was partly due to an effect of female mating status on offspring tarsus length. When nestling gro

Compact acceleration of energetic neutral atoms using high intensity laser-solid interaction

Recent advances in high-intensity laser-produced plasmas have demonstrated their potential as compact charge particle accelerators. Unlike conventional accelerators, transient quasi-static charge separation acceleration fields in laser produced plasmas are highly localized and orders of magnitude larger. Manipulating these ion accelerators, to convert the fast ions to neutral atoms with little cha

Intrasexual competition among polygynously mated female starlings (Sturnus vulgaris)

In southern Sweden, the starling (Sturnus vulgaris) has a variable mating system with some males mating monogamously and others attracting several females. Mating status affected the reproductive success of females: monogamous and primary females laid larger clutches and fledged more and heavier young than secondary females. This pattern was explained by female competition for male help, with the

Paternal care in the European starling, Sturnus vulgaris: nestling provision

The extent to which male birds in polygynous species with biparental care assist in nestling feeding often varies considerably between nests of different mating status. Both how much polygynous males assist and how they divide their effort between nests may have a profound effect on the evolution of mating systems. In this study we investigated how males in the facultatively polygynous European st

Linking content and technology : on the geography of innovation networks in the Bergen media cluster

This paper deals with the geography of innovation networks and analyses combinatorial knowledge dynamics from a single cluster perspective. Addressing firms in the media cluster in Bergen, Norway, we examine how and from where companies acquire and combine different types of knowledge for their innovation activities. The empirical analysis, which is based on structured interviews with 22 media com

Equilibrium oxygen storage capacity of ultrathin CeO2-δ depends non-monotonically on large biaxial strain

Elastic strain is being increasingly employed to enhance the catalytic properties of mixed ion-electron conducting oxides. However, its effect on oxygen storage capacity is not well established. Here, we fabricate ultrathin, coherently strained films of CeO2-δ between 5.6% biaxial compression and 2.1% tension. In situ ambient pressure X-ray photoelectron spectroscopy reveals up to a fourfold enhan

Geant4-aided Quantum State Selective Decay Spectroscopy of 213Ra

Utilizing the excellent mass resolving power of SHIPTRAP and the charged-particle-g multicoincidence setup TASISpec, the decay path of the 213Ra ground state can be exclusively studied. Based on virtual experiments with Geant4 it is possible to refine the a-branching ratios of the 213Ra ground state as well as g-ray branching ratios in the 209Rn daughter. The present study provides a proof of conc

Measurement of W± and Z-boson production cross sections in pp collisions at s=13 TeV with the ATLAS detector

Measurements of the W±→ℓ±ν and Z→ℓ+ℓ− production cross sections (where ℓ±=e±,μ±) in proton–proton collisions at s=13 TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb−1. The total inclusive W±-boson production cross sections times the single-lepton-flavour branching ratios are σW+ tot=11.83±0.02 (stat

Prolonged stopover duration characterises migration strategy and constraints of a long-distance migrant songbird

Stopover behaviour is a central element of migration strategies. But in recent geolocator studies, despite now being able to track individual songbirds during their entire migration, their stopover behaviour has received little attention. We used light-sensitive geolocators to identify the migratory routes and schedules of 12 northern wheatears (Oenanthe oenanthe) breeding in Sweden. Three geoloca

Is centre-based provision of hearing aids better than community-based provision? A cluster-randomized trial among adolescents in Bangladesh

Purpose: In response to the need for hearing aids in low-income countries, an approach to provide hearing aids through trained community workers was developed. This study compares the effectiveness of the community-based approach with that of a centre-based approach. Methods: One hundred and forty adolescents (56% girls; 12–18 years; mean: 15 years) from eleven sub-districts participated in a clus

Nestling American robins compete with siblings by begging

The evolution of intense begging by dependent nestling birds has recently been the subject of several theoretical papers. The interesting problem here is that nestlings should be able to communicate their nutritional status to parents in ways that are less costly energetically and less likely to attract predators. Thus, conspicuous begging behaviour is thought to have evolved as a result of either
