The data-driven nature of deep learning (DL) models for semantic segmentation requires a large number pixel-level annotations. However, large-scale and fully labeled medical datasets are often unavailable practical tasks. Recently, partially supervised methods have been proposed to utilize images with incomplete labels in the domain. To bridge methodological gaps (PSL) under data scarcity, we p...

The regioselectivity of the conjugate nucleophilic addition amines to vicinal di-acceptor-substituted alkenes has been studied. A set results obtained with standard primary and secondary gives some clues on relative acceptor character classical electron-withdrawing groups (EWG). We have shown in that computed inverse local nucleophilicity index can be used predict attack.

An environmentally benign procedure for the synthesis of vicinal nitrohydrins via the regioselective ring opening reaction of epoxides with nitrite anion using silica-bound 3-{2-[poly(ethylene glycol)]ethyl}-substituted 1-methyl-1H-imidazol-3-ium bromide as an effective heterogeneous phase transfer catalyst was described. Short reaction time, high yield of products, simple work-up proc...

The optical anisotropy of Au protected Fe layers grown on a vicinal W(110) surface has been investigated using reflectance anisotropy spectroscopy (RAS). Iron nanostripes formed at submonolayer coverage, as well as Fe layers up to 3 ML coverage, were protected by 12 and 16 nm gold caps and measured ex situ under ambient conditions. The RAS is dominated by structures originating in the interfaci...

Z-Enediynes are prepared by a vicinal dialkynylation of triaryl(arylethynyl)phosphonium cations. The method, which proceeds under mild transition metal-free conditions, can be conducted on multigram scale as a one-pot, phosphine-mediated synthetic cycle giving enediyne products with excellent control of configuration.
