In this paper, the performance of C-band synthetic aperture radar (SAR) Gaofen-3 (GF-3) quad-polarization Stripmap (QPS) data is assessed for classifying late spring and summer sea ice types. The investigation based on 18 scenes GF-3 QPS acquired in Arctic Ocean 2017. study, floe (FI), brash (BI) between floes open water (OW, ice-free area) were classified a mini residual convolutional network,...

Adaptive cross-region-based guided image filtering (ACR-GIF) is a commonly used cost aggregation method. However, the weights of points in adaptive cross-region (ACR) are generally not considered, which affects accuracy disparity results. In this study, we propose an improved method to address issue. First, orthogonal weight proposed according structural feature ACR, and then each point ACR com...

Crystals of the one-dimensional organic-inorganic lead iodide-based compound catena-poly[bis-(piperazine-1,4-diium) [[tetra-iodido-plumbate(II)]-μ-iodido] iodide monohydrate], (C4N2H12)2[PbI5]I·H2O, were obtained by slow evaporation at room temperature of a solution containing lead iodide and piperazine in a 1:2 molar ratio. Inorganic lead iodide chains, organic (C4N2H12)(2+) cations, water mol...

In this paper, we study inextensible ows in three dimensional Lie groups with a bi-invariant metric. The necessary and sucient conditions for inextensible curve ow are expressed as a partial dierential equation involving the curvatures. Also, we give some results for special cases of Lie groups.

OBJECTIVE To determine the effects of timing of onset of overweight (OW) on childhood anthropometric adiposity levels using long-term serial data from the Fels Longitudinal Study. CLASSIFICATION OW was defined as body mass index (BMI; kg/m(2)) >25, and the age at first measurement of BMI >25 was the age of onset of OW. Early onset of OW (early-OW) and late onset of OW (late-OW) were defined a...

The meshless local radial point interpolation (MLRPI) method is applied to examine the magnetohydrodynamic (MHD) ow of third grade uid in a porous medium. The uid saturates the porous space between the two boundaries. Several limiting cases of fundamental ows can be obtained as the special cases of present analysis. The variations of pertinent parameters are addressed.

Purpose: Overweight or obese children and adolescents face a lack of confidence in their physical abilities, and show poorer motor and fitness performances, compared to healthy weight peers. Therefore, the present study aimed to investigate the relationship between physical self-efficacy and VO2 max in healthy weight versus overweight female adolescents. Methods: This was a cross-sectional cor...
