Binary mass ratios: system mass not primary mass [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Abstract Binary properties are usually expressed (for good observational reasons) as a function of primary mass. It has been found that the distribution of companion masses – the mass ratio distribution – is different for different primary masses. We argue that system mass is the more fundamental physical parameter to use.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Dynamical Masses and Mass-To-Light Ratios for Globular Clusters [PDF]
Symposium - International Astronomical Union, 1975 Dynamical masses have been determined for 10 globular clusters. Comparison of the dynamically determined M/L values with those calculated from extrapolations of the observed upper main sequence/giant branch luminosity functions for M3 and M5 indicate that low mass stars (∼0.2 M⊙) comprise a large fraction of the total number.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

The study on catalytic performance of CuO/CexZr1-xO2 catalyst in carbon monoxide oxidation
上海师范大学学报. 自然科学版, 2017 A series of CuO/CexZr1-xO2 samples were prepared by incipient-wetness impregnation method with CexZr1-xO2 used as the catalyst carrier which was synthesized by co-precipitation method.The influences of the mass ratio of CeO2:ZrO2 and CuO loading were ...

Sampling systems for isotope ratio mass spectrometry of atmospheric ammonia
, 2006 Passive and active ammonia (NH3) sampling devices have been tested for their nitrogen (N) capture potential and 15N fractionation effects. Several sampling techniques produced significantly different 15NH3 signals when sampling the same NH3 source ...

Mass loss and ΔY/ΔZ ratio [PDF]
International Astronomical Union Colloquium, 1981 SummaryThe ΔY/ΔZ abundance ratio is studied taking into account mass loss from intermediate and massive stars, and the Yz vs. Z relation of Peimbert and Serrano (1980a).

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
