To address the huge labeling cost in large-scale point cloud semantic segmentation, we propose a novel hybrid contrastive regularization (HybridCR) framework weakly-supervised setting, which obtains competitive performance compared to its fully-supervised counterpart. Specifically, HybridCR is first leverage both consistency and employ with pseudo an end-to-end manner. Fundamentally, explicitly effectively considers similarity between local neighboring points global characteristics of 3D...
[Reaction: see text]. A Pd(II)-catalyzed conjugate addition of arylboronic acid to alpha,beta-unsaturated ketones, aldehydes, esters, etc. in the presence 2,2'-bipyridine was developed. mechanism involving transmetalation, insertion carbon-carbon double bond into C-Pd bond, and protonolysis resulting is proposed. The reaction conditions are mild yield high. crucial for inhibit beta-hydride elimination.
Cationic Pd(II) complex-catalyzed addition of arylboronic acids to aldehydes with low catalyst loading was developed high yields. One-pot synthesis unsymmetrical triarylmethanes from acids, aryl aldehydes, and electron-rich arenes achieved in
Cationic Pd(II)-catalyzed addition of arylboronic acids to β,β-disubstituted enones in high yields was developed. This method provided an efficient for the construction quaternary carbon centers, and only 0.5 mol % Pd(II) catalyst needed.
A new type of polymer highly resistant to nonspecific protein adsorption is reported. Poly(N-methyl-β-alanine) (PMeA) and poly(N-ethyl-β-alanine) (PEtA) synthesized via cobalt-catalyzed carbonylative polymerization N-methylaziridine N-ethylaziridine were end-functionalized with thiol groups grafted onto Au surfaces. Protein was studied by the surface plasmon resonance (SPR) method. The amounts representative single proteins adsorbed PMeA- PEtA-grafted surfaces below detection limit SPR at...
ABSTRACT A Salen‐Co(III)‐Cl catalyzed copolymerization strategy is developed for the controlled synthesis of polycarbonate‐ b ‐polyester block copolymers through a one‐pot process involving CO 2 , 4‐vinyl‐1‐cyclohexene‐1,2‐epoxy (VCHO), and ε‐caprolactone (ε‐CL). This procedure extended to VCHO, lactide. The catalytic system designed optimized with temperature acting as triggers switch between /epoxide ε‐CL homopolymerization. In addition, introducing water chain transfer agent reduced...
Cobalt-catalyzed cyclization of CO, imine, and epoxide has been developed. A convenient catalyst system composed Co2(CO)8 LiCl is identified, the substrate scope explored. The reaction provides an efficient method for synthesis substituted 1,3-oxazinan-4-ones.
Rutile titanium dioxide (TiO 2 )/poly(methyl methacrylate‐acrylic acid‐butyl acrylate) nanocomposites were synthesized via seeded emulsion polymerization and characterized by Fourier transmission infrared, dynamic light scattering, X‐ray diffraction, ultraviolet–visible (UV–vis) spectroscopy, scanning electron microscopy, thermogravimetric analysis to study their UV‐shielding property.
