Abstract: A user equipment assistance information (UAI) negotiation method, for a user equipment (UE) of mobile communication includes receiving a first OtherConfig element of an RRC reconfiguration message comprising a plurality of configuration parameters with SETUP values from a network terminal; sending a first UAI including a first value of a first configuration parameter of the configuration parameters to the network terminal; and receiving a first RRC reconfiguration message corresponding to the first UAI from the network terminal.

Abstract: Provided is a block copolymer composition which contains a block copolymer having a specific molecular structure and has a molecular weight distribution within an appropriate range. A polymerizable composition containing a macromonomer (A) which has a group having a radical-reactive unsaturated double bond at one terminal of a poly(meth)acrylate segment, a vinyl monomer (B), and an organic iodine compound (C), or a polymerizable composition containing a macromonomer (A), a vinyl monomer (B), an azo-based radical polymerization initiator (E), and iodine is polymerized to obtain a block copolymer composition containing a block copolymer in which constitutional units of all blocks are derived from vinyl monomers and at least one block has a branched structure.

Abstract: A two-dimensional data matrix structure includes a first substrate, a first metal layer disposed on the first substrate, a second substrate disposed on the first metal layer, and a second metal layer disposed on the second substrate. The first metal layer has a plurality of sections and a plurality of empty regions formed according to a two-dimensional data matrix pattern. The first substrate, the second substrate, and the second metal layer commonly have a plurality of through holes, and positions of the through holes correspond to positions of the empty regions. The second substrate and the second metal layer commonly have a plurality of blind holes, and positions of the blind holes correspond to positions of the sections. The sections are exposed through the blind holes, and the configuration of the through holes and the blind holes is the two-dimensional data matrix pattern when viewed from above.
