TL;DR: The standard index of microbial air contamination (IMA) is described, which quantifies the microbial flow directly related to the contamination of surfaces coming from microbes that reach critical points by falling on to them.

TL;DR: In this paper, a search for the standard model Higgs boson decaying to bb¯ when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν), W(τν), H, Z(μμ), Z(ee, H, and Z(νν), where the search is performed in data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at s√=7
Abstract: A search for the standard model Higgs boson (H) decaying to bb¯ when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν)H, W(τν)H, Z(μμ)H, Z(ee)H, and Z(νν)H. The search is performed in data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at s√=7 TeV and up to 18.9 fb−1 at s√=8 TeV, recorded by the CMS experiment at the LHC. An excess of events is observed above the expected background with a local significance of 2.1 standard deviations for a Higgs boson mass of 125 GeV, consistent with the expectation from the production of the standard model Higgs boson. The signal strength corresponding to this excess, relative to that of the standard model Higgs boson, is 1.0±0.5.

TL;DR: It is concluded that the stochastic gravitational-wave background from binary black holes, created from the incoherent superposition of all the merging binaries in the Universe, is potentially measurable by the Advanced LIGO and Advanced Virgo detectors operating at their projected final sensitivity.
Abstract: The LIGO detection of the gravitational wave transient GW150914, from the inspiral and merger of two black holes with masses $\gtrsim 30\, \text{M}_\odot$, suggests a population of binary black holes with relatively high mass. This observation implies that the stochastic gravitational-wave background from binary black holes, created from the incoherent superposition of all the merging binaries in the Universe, could be higher than previously expected. Using the properties of GW150914, we estimate the energy density of such a background from binary black holes. In the most sensitive part of the Advanced LIGO/Virgo band for stochastic backgrounds (near 25 Hz), we predict $\Omega_\text{GW}(f=25 Hz) = 1.1_{-0.9}^{+2.7} \times 10^{-9}$ with 90\% confidence. This prediction is robustly demonstrated for a variety of formation scenarios with different parameters. The differences between models are small compared to the statistical uncertainty arising from the currently poorly constrained local coalescence rate. We conclude that this background is potentially measurable by the Advanced LIGO/Virgo detectors operating at their projected final sensitivity.

TL;DR: This large study has provided additional robust evidence for the existence of neuropsychiatric subsyndromes in AD.
Abstract: Background/Aims: The aim of this study was to identify neuropsychiatric subsyndromes of the Neuropsychiatric Inventory in a large sample of outpatients with Alzheimer's disease (AD). Methods: Cross-sectional data of 2,354 patients with AD from 12 centres from the European Alzheimer's Disease Consortium were collected. Principal component analysis was used for factor analysis. Results: The results showed the presence of 4 neuropsychiatric subsyndromes: hyperactivity, psychosis, affective symptoms and apathy. The subsyndrome apathy was the most common, occurring in almost 65% of the patients. Conclusion: This large study has provided additional robust evidence for the existence of neuropsychiatric subsyndromes in AD.

TL;DR: In this article, a measurement of the cosmic ray positron fraction in the energy range of 1 −30 GeV was presented, based on data taken by the AMS-01 experiment during its 10-day Space Shuttle flight in June 1998.
