Global trait–environment relationships of plant communities

Verified

Helge Bruelheide, Jürgen Dengler, Oliver Purschke, Jonathan Lenoir et al.

Journal: Nature Ecology & EvolutionYear: 2018Citations: 714

Plant functional traits directly affect ecosystem functions. At the species level, trait combinations depend on trade-offs representing different ecological strategies, but at the community level trait combinations are expected to be decoupled from these trade-offs because different strategies can f...

Improved limits on dark matter annihilation in the Sun with the 79-string IceCube detector and implications for supersymmetry

Verified

M. G. Aartsen, K. Abraham, M. Ackermann, J. Adams et al.

Journal: Journal of Cosmology and Astroparticle PhysicsYear: 2016Citations: 139

We present an improved event-level likelihood formalism for including neutrino telescope data in global fits to new physics. We derive limits on spin-dependent dark matterproton scattering by employing the new formalism in a re-analysis of data from the 79-string IceCube search for dark matter annih...

An interaction between basement membrane and Alzheimer amyloid precursor proteins suggests a role in the pathogenesis of Alzheimer's disease.

Verified

Suree Narindrasorasak, Richard Altman, Patricia A. Gonzalez‐DeWhitt, B. D. Greenberg et al.

Journal: PubMedYear: 1995Citations: 74

BACKGROUND: Extracellular matrix proteins (ECMPs) of the basement membrane type, such as the heparan sulfate proteoglycan perlecan, laminin, entactin, collagen IV, and fibronectin are present in and have been implicated in the genesis of amyloids. As in many forms of amyloid, perlecan, laminin, coll...

Development of a general analysis and unfolding scheme and its application to measure the energy spectrum of atmospheric neutrinos with IceCube

Verified

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et al.

Journal: The European Physical Journal CYear: 2015Citations: 54

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 selection which uses a Minimum Redundancy Maximum Relevance algorithm to select the relevant ...

Validation of a Dish-Based Semiquantitative Food Questionnaire in Rural Bangladesh

Verified

Pi‐I D. Lin, Sabri Bromage, Md. Golam Mostofa, Joseph Allen et al.

Journal: NutrientsYear: 2017Citations: 40

A locally validated tool was needed to evaluate long-term dietary intake in rural Bangladesh. We assessed the validity of a 42-item dish-based semi-quantitative food frequency questionnaire (FFQ) using two 3-day food diaries (FDs). We selected a random subset of 47 families (190 participants) from a...
