Open AccessErratum to: Search for non-relativistic magnetic monopoles with IceCube
In the analyses, published in Ref. [1], the exclusion limits are calculated in dependence of the mean free path of the magnetic monopole - nucleon catalysis interaction.

Open AccessAll-flavour search for neutrinos from dark matter annihilations in the Milky Way with IceCube/DeepCore
We present the first IceCube search for a signal of dark matter annihilations in the Milky Way using all-flavour neutrino-induced particle cascades. The analysis focuses on the DeepCore sub-detector of IceCube...

Open AccessSearches for relativistic magnetic monopoles in IceCube
Various extensions of the Standard Model motivate the existence of stable magnetic monopoles that could have been created during an early high-energy epoch of the Universe. These primordial magnetic monopoles ...

Cognitive status is a determinant of health resource utilization among individuals with a history of falls: a 12-month prospective cohort study
Falls are a costly public health problem worldwide. The literature is devoid of prospective data that identifies factors among fallers that significantly drive health care resource utilization. We found that c...

Atomic-scale electronic structure of the cuprate d-symmetry form factor density wave state
A detailed scanning tunnelling microscopy study of the cuprate superconductor Bi2Sr2CaCu2O8+x reveals the microscopic origin of the d-symmetry form factor density wave that exists in the pseudogap phase of this m...

Open AccessSearch for dark matter annihilation in the Galactic Center with IceCube-79
The Milky Way is expected to be embedded in a halo of dark matter particles, with the highest density in the central region, and decreasing density with the halo-centric radius. Dark matter might be indirectly...

Open AccessDevelopment of a general analysis and unfolding scheme and its application to measure the energy spectrum of atmospheric neutrinos with IceCube
We present the development and application of a generic analysis scheme for the measurement of neutrino spectra with the IceCube detector. This scheme is based on regularized unfolding, preceded by an event se...

Identifying the 'fingerprint' of antiferromagnetic spin fluctuations in iron pnictide superconductors
The mechanism holding Cooper pairs together in iron-based superconductors is highly debated. Finding the fingerprint of the pairing mechanism would be a leap forward.

Open AccessMultipole analysis of IceCube data to search for dark matter accumulated in the Galactic halo
Dark matter which is bound in the Galactic halo might self-annihilate and produce a flux of stable final state particles, e.g. high energy neutrinos. These neutrinos can be detected with IceCube, a cubic-kilom...

Open AccessSearch for non-relativistic magnetic monopoles with IceCube
The IceCube Neutrino Observatory is a large Cherenkov detector instrumenting \(1\,\mathrm {km}^3\) ...

Enigmatic nematic
Iron pnictide superconductors often feature nematic, symmetry-breaking electronic states. These phenomena are now found to persist into the tetragonal phase of NaFeAs — a new piece of information that may help...

Imaging Cooper pairing of heavy fermions in CeCoIn5
By pushing scanning tunnelling spectroscopy down to millikelvin temperatures, it is now possible to image a heavy fermion superconductor and measure the superconducting gap symmetry, with gap nodes in unexpect...

Anisotropic impurity states, quasiparticle scattering and nematic transport in underdoped Ca(Fe1−xCox)2As2
When CaFe2As2 is lightly doped with Co an electronic liquid-crystalline state emerges, which becomes the ‘parent’ state of high-temperature superconductivity in this ferropnictide. A spectroscopic imaging study s...

Generalized Rotational Susceptibility Studies of Solid 4He
Using a novel SQUID-based torsional oscillator (TO) technique to achieve increased sensitivity and dynamic range, we studied TO’s containing solid 4He. Below ∼250 mK, the TO resonance frequency f increases and it...

Examining the relationship between specific cognitive processes and falls risk in older adults: a systematic review
This systematic review aims to establish which cognitive domains are associated with falls or falls risk. Recent evidence suggests that impaired cognition increases seniors’ risk of falling. The purpose of thi...

Visualization of the emergence of the pseudogap state and the evolution to superconductivity in a lightly hole-doped Mott insulator
Scanning tunnelling microscopy images of the evolution of the pseudogap phase of a hole-doped cuprate superconductor suggest that it emerges in localized clusters that grow with increasing do**. Moreover, th...

SF-6D and EQ-5D result in widely divergent incremental cost-effectiveness ratios in a clinical trial of older women: implications for health policy decisions
Using two instruments (SF-6D and EQ-5D) to estimate quality adjusted life years (QALYs), we conducted an economic evaluation of a 12-month randomized controlled trial with a 12-month follow-up study in older w...

Guidelines for conducting and reporting economic evaluation of fall prevention strategies
Falls in older people result in substantial health burden. Compelling evidence indicates that falls can be prevented. We developed comprehensive guidelines for economic evaluations of fall prevention intervent...

Economic evaluation of dose–response resistance training in older women: a cost-effectiveness and cost-utility analysis
We estimated the incremental cost-effectiveness of a once-weekly or twice-weekly resistance training intervention compared with balance and tone classes in terms of falls prevented and quality-adjusted life ye...

Open AccessSearch for relativistic magnetic monopoles with the AMANDA-II neutrino telescope
We present the search for Cherenkov signatures from relativistic magnetic monopoles in data taken with the AMANDA-II detector, a neutrino telescope deployed in the Antarctic ice cap at the Geographic South Pole. ...
