Modeling the plasmasphere to topside ionosphere scale height ratio
Journal of Space Weather and Space Climate, 2015 A new model of plasmasphere to topside ionosphere scale heights ratio is developed, based on topside electron density (Ne) profiles deduced from the International Satellites for Ionospheric Studies (ISIS)-1 satellite measurements.

Large-scale age-dependent skewed sex ratio in a sexually dimorphic avian scavenger. [PDF]
PLoS ONE, 2012 Age-dependent skewed sex ratios have been observed in bird populations, with adult males generally outnumbering females. This trend is mainly driven by higher female mortality, sometimes associated with anthropogenic factors.

An estimation method of full scale performance for pulling type podded propellers
International Journal of Naval Architecture and Ocean Engineering, 2014 This paper presents a new estimation method of full scale propulsive performance for the pulling type podded propeller. In order to estimate the drag of pod housing, a drag velocity ratio, which includes the effects of podded propeller loading and ...

Invariant foreground occupation ratio for scale adaptive mean shift tracking
IET Computer Vision, 2015 The mean shift algorithm has been introduced successfully into the field of computer vision to be an efficient approach for visual tracking but the tracker has been awkward in handling the scale change of the object.

Analyzing the rent-to-price ratio for the housing market at the micro-spatial scale
International Journal of Strategic Property Management, 2018 The rent-to-price ratio is one of the popular indicators for monitoring the property market. This study explores micro-scale spatial dynamics of the ratio for houses at the individual property level in Seoul, South Korea. We match the apartment unit sold

, 1996 Recent developments in string duality suggest that the string scale may not be irrevocably tied to the Planck scale. Two explicit but unrealistic examples are described where the ratio of the string scale to the Planck scale is arbitrarily small ...

The Scale Effect Study on the Transient Fluid–Structure Coupling Performance of Composite Propellers
Journal of Marine Science and Engineering, 2022 In order to predict the fluid–structure coupling performance of a full-scale composite propeller under a wake flow field behind a full ship, a bidirectional transient fluid–structure coupling algorithm was established.

Conformal Symmetry as a Template: Commensurate Scale Relations and Physics Renormalization Schemes [PDF]
, 1999 Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the "generalized Crewther relation", which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum ...

Leading logarithmic QCD corrections to the B_s --> \gamma \gamma decays in the two Higgs doublet model [PDF]
, 1997 We calculate the leading logarithmic QCD corrections to the decay B_s --> \gamma \gamma in the two Higgs doublet model (2HDM) including O_7 type long distance effects and estimate the restrictions of the 2HDM parameters, tan\beta and m_H, using the ...
