Abstract: Proposed are a core-satellite micelle containing a tetra-block copolymer and a preparation method thereof. The core-satellite micelle includes a core, a shell surrounding the core, and a plurality of satellite domains positioned inside the shell. The core-satellite micelle contains a tetra-block copolymer represented by Structural Formula 1 below. The shell includes a first-monomer first block A1 and a first-monomer second block A2, and the satellite domain includes a second-monomer first block B1 and a second-monomer second block B2. The core-satellite micelle is foiled through self-assembly of the tetra-block copolymer, thereby having a larger interfacial contact area than existing block-copolymer micelles. Therefore, the core-satellite micelle can be used in next-generation nanotechnology applications such as drug delivery systems, porous catalyst materials, and sensors. A1-B1-A2-B2 [Structural Formula 1] In Structural Formula 1, A1 is a first-monomer first block, B1 is a second-monomer first block, A2 is a first-monomer second block, and B2 is a second-monomer second block.

Abstract: Provided is a method of forming a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions of an object. The method includes: preparing a micro/nanopipette having a tip with an inner diameter which is substantially the same as the diameter of the micro/nanowire to be formed; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; brining the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette from the object at a pulling speed lower than or equal to a predetermined critical speed (νc) to obtain a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip.

Abstract: Provided is a method of fabricating a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions on an object. The method comprises: preparing a micro/nanopipette having a tip with an inner diameter (dpt) which is substantially the same as the diameter of the micro/nanowire to be fabricated; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; bringing the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette apart from the object at a pulling speed lower than or equal to a predetermined critical pulling speed (vc) to fabricate a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip (dpt). The critical pulling speed (vc) is defined by a maximum limit of the pulling speed at which the micro/nanowire to be fabricated has the same diameter as the inner diameter of the micro/nanopipette tip (dpt).

Abstract: A method and a device for transmitting a signal by using a polar code are provided. The method includes generating a first codeword by applying the polar code to an input signal, dividing the first codeword into a plurality of partial vectors, allocating a shaping bit to the input signal when at least one of the plurality of partial vectors does not satisfy a preset Hamming weight condition, generating a second codeword by applying the polar code to the input signal to which the shaping bit is allocated, and transmitting a signal based on the second codeword.

Abstract: The present disclosure provides is a high-speed image recognition method and apparatus using a 3D CNN. The high-speed image recognition method using the 3D CNN includes: inputting each of a first image clips among image clips constituting an input image to the 3D CNN; acquiring softmax function values calculated in the 3D CNN with respect to each of the first image clips; calculating a score margin by using the softmax function values; comparing the score margin with a predetermined threshold value to determine whether to input at least one additional image clip other than the first image clips among the image clips constituting the input image to the 3D CNN. Therefore, a calculation speed for image recognition can be improved.
