Abstract: The present disclosure relates to ultra-high speed digital signal integrity improving structures. Each structure in the present disclosure includes a first unit structure and a second unit structure of the same or different shapes arranged to face each other on the left and right sides along a longitudinal direction of a balanced line, centered around a coplanar stripline (CPS) or parallel stripline (PSL) formed on a substrate. At least one of the first unit structure and the second unit structure includes a first side close to the balanced line and having a linear or curve shape; a second side facing the first side; and left and right sides connecting the first side and the second side. Here, the width of the first side is less than or equal to that of the second side, the left and right sides have a linear or non-linear slope, and the width from the first side to the second side is configured to change continuously or discontinuously. When the structures of the present disclosure are disposed around a balanced line, it has the advantage of being able to recover the distorted phase autonomously while rejecting a common-mode signal in a frequency band up to 40 GHz or more.

Abstract: The present invention relates to a method of using a recombinant antibacterial protein, termed Ablysin, for effectively killing multidrug-resistant pathogenic bacteria. The recombinant protein Ablysin is administered to prevent or treat infectious diseases caused by the antibiotic-resistant bacteria Acinetobacter baumannii. Ablysin can be widely used in antibiotics, disinfectants, food additives, feed additives, and the like. In particular, the Ablysin protein uses peptidoglycan, a component of the cell wall of bacteria, as a substrate and exhibits bacterial killing ability due to peptidoglycan degradation. The Ablysin of the present invention can be applied in the pharmaceutical industry, food industry, biotechnology, or similar industries, as the protein effectively kills bacteria at a desired place or in a target substance without problems of resistance that occurs in other antimicrobial agents.

Abstract: The present disclosure relates to a membrane filter for water and wastewater treatment including a membrane filter, hydrophilic polymers formed on the membrane filter; and quorum quenching microorganisms cross-linked with the membrane filter by the hydrophilic polymer. The quorum quenching microorganisms are attached to the surface of the membrane filter for water and wastewater treatment, resulting in a higher initial permeation pressure than a conventional membrane, but the quorum quenching microorganisms may effectively prevent the phenomenon of quorum sensing, allowing the formation of a biofilm, thereby improving the life of the membrane filter for water and wastewater treatment.

Abstract: The present invention relates to a composition for inhibiting skin pigmentation through enhanced autophagy activity, comprising procyanidin A2 and quercetin as active ingredients. The combination of procyanidin A2 and quercetin compounds not only inhibits tyrosinase but also increases autophagy activity, thus showing remarkable effectiveness in inhibiting melanin synthesis. Therefore, this composition can be advantageously used in various materials, including food products, cosmetic compositions, and pharmaceutical compositions, associated with skin pigmentation.
