Abstract—We propose a novel joint probabilistic model that correlates a new probabilistic shape model with the corresponding global intensity distribution to segment multiple abdominal organs simultaneously. Our probabilistic shape model estimates the probability of an individual voxel belonging to the estimated shape of the object. The probability density of the estimated shape is derived fr…
Abstract—Memory bandwidth is critical to GPGPU performance. Exploiting locality in caches can better utilize memory bandwidth. However, memory requests issued by excessive threads cause cache thrashing and saturate memory bandwidth, degrading performance. In this paper, we propose adaptive cache and concurrency allocation (CCA) to prevent cache thrashing and improve the utilization of bandwid…
The ground-state properties of even–even nuclei from Z = 10 to Z = 20 are systematically studied in covariant density functional theory with the point-coupling interaction PC-PK1. The triaxiality effect on nuclear binding energy, including the mean-field part and rotational correction energy, is examined.We find that 38Si, 46S, and 48S exhibit considerable triaxial deformation. The result…
Abstract. A soft-phase intercalating process to synthesize mesostructured plasticine by using amphiphilic triblock copolymer F127 as a structure-directing agent, reverse triblock copolymer 25R4 as an intercalating soft matter, and soluble phenolic resin as a carbon source is demonstrated. The ‘‘plasticine” has interlayer organic–organic hybrid structure, which is emplastic, sticky, …
Abstract. Sodium montmorillonite (Na-MMT) was modified with various amounts of aminopropylisooctyl polyhedral oligomeric silsequioxane (POSS) and a second surfactant (alkyl ammonium based) via ionexchange reactions. Interlayer spacing, interlamellar structure, and thermal and surface properties of these organoclays were characterized by wide angle X-ray diffraction, thermogravimetric analys…
Abstract The inhibition behavior of low carbon steel in 1 M HCl by L-tryptophan was investigated with weight loss experiment and Tafel polarization curve in the used temperature range (298–328 K). All the experimental results show that L-tryptophan has excellent corrosion inhibition performance and the most effective concentration of inhibitor is 1 x 10-2 mol L-1. The Tafel polarization cu…
ABSTRACT Three new fused-ring pyrazine derivatives end-functionalized with trifluoromethylphenyl groups have been synthesized. The effect of a fused-ring pyrazine core on the thermal, electronic, optical, thin film morphology, and organic field-effect transistor (OFET) properties was investigated both experimentally and theoretically. Electrochemistry measurements and density functional theor…
We demonstrate, for the first time, the application of ordered mesoporous carbons with large pore sizes prepared from the surfactant-templating approach in efficient disposal of wastewater containing bulky dye molecules. The adsorption amount for the bulky dye (methylthionine chloride, fuchsin basic, rhodamine B, brilliant yellow, methyl orange, or Sudan G) is almost twice that of the activa…
