A global synthesis reveals biodiversity-mediated benefits for crop production
(2019)Science AdvancesHuman land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield–related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for pollination; biological pest control; and ...Journal Article -
Global patterns and drivers of ecosystem functioning in rivers and riparian zones
(2019)Science AdvancesRiver ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater than 1000 river and riparian sites. We ...Journal Article -
Minimal information for studies of extracellular vesicles 2018 (MISEV2018): a position statement of the International Society for Extracellular Vesicles and update of the MISEV2014 guidelines
(2019)Journal of Extracellular VesiclesThe last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and ...Journal Article -
Deep-biosphere methane production stimulated by geofluids in the nankai accretionary complex
(2018)Science AdvancesMicrobial life inhabiting subseafloor sediments plays an important role in Earth’s carbon cycle. However, the impact of geodynamic processes on the distributions and carbon-cycling activities of subseafloor life remains poorly constrained. We explore a submarine mud volcano of the Nankai accretionary complex by drilling down to 200 m below the summit. Stable isotopic compositions of water and carbon compounds, including clumped methane ...Journal Article -

Jet production rates in association with W and Z bosons in pp collisions at root s=7 TeV
(2012)Journal of High Energy PhysicsMeasurements of jet production rates in association with W and Z bosons for jet transverse momenta above 30 GeV are reported, using a sample of proton-proton collision events recorded by CMS at s√=7TeV, corresponding to an integrated luminosity of 36 pb − 1. The study includes the measurement of the normalized inclusive rates of jets σ(V + ≥ n jets)/σ(V), where V represents either a W or a Z. In addition, the ratio of W to Z cross sections ...Journal Article -
Measurement of energy flow at large pseudorapidities in pp collisions at √s = 0.9 and 7 TeV
(2011)Journal of High Energy Physicshe energy flow, dE/dη, is studied at large pseudorapidities in proton-proton collisions at the LHC, for centre-of-mass energies of 0.9 and 7 TeV. The measurements are made using the CMS detector in the pseudorapidity range 3.15 < |η| < 4.9, for both minimum-bias events and events with at least two high-momentum jets. The data are compared to various pp Monte Carlo event generators whose theoretical models and input parameter values are ...Journal Article -
Search for new physics with jets and missing transverse momentum in pp collisions at s√=7 TeV
(2011)Journal of High Energy PhysicsA search for new physics is presented based on an event signature of at least three jets accompanied by large missing transverse momentum, using a data sample corresponding to an integrated luminosity of 36 pb−1 collected in proton-proton collisions at s√=7 TeV with the CMS detector at the LHC. No excess of events is observed above the expected standard model backgrounds, which are all estimated from the data. Exclusion limits are presented ...Journal Article -
Measurement of the t(t)over-bar production cross section and the top quark mass in the dilepton channel in pp collisions at root s=7 Tev
(2011)Journal of High Energy PhysicsThe tt¯ production cross section and top quark mass are measured in proton-proton collisions at s√=7 TeV in a data sample corresponding to an integrated luminosity of 36 pb−1 collected by the CMS experiment. The measurements are performed in events with two leptons (electrons or muons) in the final state. Results of the cross section measurement in events with and without b-quark identification are obtained and combined. The measured value ...Journal Article -
Long-range and short-range dihadron angular correlations in central PbPb collisions at root s(NN)=2.76 TeV
(2011)Journal of High Energy PhysicsFirst measurements of dihadron correlationsfor charged particles are presented for central PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76TeV over a broad range in relative pseudorapidity (∆η) and the full range of relative azimuthal angle (∆ϕ). The data were collected with the CMS detector, at the LHC. A broadening of the away-side (∆ϕ ≈ π) azimuthal correlation is observed at all ∆η, as compared to the measurements ...Journal Article
