The Distance to the Hercules Supercluster. II. Application of Tertiary Indicators and an Estimate of the Hubble Constant 来自 Semantic Scholar 喜欢 0 阅读量: 18 作者:RJ Buta,HGJ Corwin 摘要: Using data provided in a previous paper, we calculate distances on the zero point of de Vaucouleurs'...
(η=Lγ/E˙) and pulsar parameters for young radio-selected gamma-ray pulsars with known distance information in the first gamma-ray pulsar catalog reported by Fermi/LAT.We have introduced three generation-order parameters to describe the gamma-ray emission properties of pulsars,and find a ...
The detection of radial and non-radial solar-like oscillations in thousands of G-K giants with CoRoT and Kepler is paving the road for detailed studies of stellar populations in the Galaxy. The available average seismic constraints allow a precise and largely model-independent determination of stell...
To capture geographic distance we use a large array of controls, capturing both simple geodesic distance, distance along the longitudinal and latitudinal dimensions, and binary indicators of micro-geography such as whether the countries in a pair are contiguous, are islands, are landlocked, or share...
Measuring geopolitical distance and its limitations Four indicators capture some of the contours of that geometry. Economies vary in how much they trade in comparison to their size; this is their trade intensity. Economies also vary in their patterns of trade partners, in both where they are, or...
Seven of the 12 antibiotics evaluated in this study are critically important to human health and another four of the antibiotics evaluated are highly important to human health, according to World Health Organization (WHO) guidelines. Significant differences existed in amounts of indicators from pre- ...

The use of Geographical Information System (GIS) based on water quality information system and spatial analysis with Inverse Distance Weighted (IDW) interpolation enabled the mapping of water quality indicators in watershed of Wadi El Bey, Tunisia. Using 13 sampling locations, water quality indicators...
In another embodiment, the processing device 532 may develop the non-linear model based on a plurality of position points and a plurality of direction indicators. In another embodiment, the processing device 532 may generate a plurality of correlation models and select one of the models to derive...
