Background and Aim: It remains unknown how and where the mitral valve leaks in functional mitral regurgitation.The objective of the current study was to quantify ackermans lace curtains the geometry and position of the leaflet free edges in order to reveal gapping mechanism of the mitral valve, and develop a plug technique to prevent mitral regurgi

The opacity of clouds is the main problem for optical and thermal space-borne sensors, like the Moderate-Resolution Imaging Spectroradiometer (MODIS).Especially during polar nighttime, the low thermal contrast between clouds and the underlying snow/ice results in deficiencies of the MODIS cloud mask and affected products.There are different approac

Texture classification algorithms using local binary pattern (LBP) and its variants usually can achieve attractive results.However, the selected rotation invariant structural patterns in numerous LBP gewehr 91 variants are not absolutely continuous invariant to any rotation angle.To improve the classification effectiveness on this occasion, in this
