This disclosure provides systems, methods, and devices related to a metasurface skin cloak. In one aspect, a metasurface skin cloak includes a dielectric layer and a plurality of blocks disposed on the dielectric layer. The dielectric layer is disposed over a surface including a feature on the surface. Each block of the plurality of blocks has a shape that is symmetric about two perpendicular axes. The metasurface skin can render the feature on the surface not optically detectable.

Federating multiple-level master data management systems may include a first set of master data management nodes having one or more common characteristics. A first group master data management node may be assigned to centrally manage the first set of master data management nodes, the first group master data management node maintaining master data management functionalities at a group level and providing a single logical view of master data to the first set of master data management nodes. Each master data management node in the first set has data access link with the first group master data management node based on implementation style of said each master data management node.
摘要:
The chiral compound S-5-substituted-N-2′-(thienyl-2-yl-)ethyl-tetralin-2-amine or its chiral acid salts and preparation method thereof are disclosed, and the method for preparing Rotigotine by using the chiral compound is also disclosed. Racemic 5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine (compound 1) is resolved by using a conventional chiral acid to obtain an optically pure chiral acid salt of S-5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine, which is then dissociated to obtain S-5-substituted-N-2′-(thien-2-yl-)ethyl-tetralin-2-amine (compound 2). The compound 2 or chiral acid salt thereof is alkylated and deprotected to produce rotigotine (compound 5).
