The photocurable and thermosetting resin composition of the present invention includes an actinic energy ray-curable resin having at least one structure represented by the following general formula, a photopolymerization initiator, a diluent, and a thermosetting component. The piercing member has a handle with a gripping surface on one end and an inwardly projecting piercing pin on the opposite end. Moreover, sparse codewords can be used to reduce baseband processing complexity on the receiver-side of the network, as sparse codewords can be detected within multiplexed codewords in accordance with message passing algorithms. An open nano-structure, is formed in a substrate. A length of the convex portion between the end portions is larger than an opening width of each of the notches.
